2022年新高考I卷之B篇
Like most of us, I try to be mindful of food that goes to waste. The arugula (芝麻菜)was to make a nice green salad, rounding out a roast chicken dinner. But I ended up working late. Then friends called with a dinner invitation. I stuck the chicken in the freezer. But as days passed, the arugula went bad. Even worse, I had unthinkingly bought way too much; I could have made six salads with what I threw out.
In a world where nearly 800 million people a year go hungry, “food waste goes against the moral grain,” as Elizabeth Royte writes in this month’s cover story. It’s jaw-dropping how much perfectly good food is thrown away — from “ugly” (but quite eatable) vegetables rejected by grocers to large amounts of uneaten dishes thrown into restaurant garbage cans.
Producing food that no one eats wastes the water, fuel, and other resources used to grow it. That makes food waste an environmental problem. In fact, Royte writes, “if food waste were a country, it would be the third largest producer of greenhouse gases in the world.”
If that’s hard to understand, let’s keep it as simple as the arugula at the back of my refrigerator. Mike Curtin sees my arugula story all the time — but for him, it's more like 12 bones of donated strawberries nearing their last days. Curtin is CEO of DC Central Kitchen in Washington, D.C., which recovers food and turns it into healthy meals. Last year it recovered more than 807,500 pounds of food by taking donations and collecting blemished (有瑕疵的) produce that otherwise would have rotted in fields. And the strawberries? Volunteers will wash, cut, and freeze or dry them for use in meals down the road.
Such methods seem obvious, yet so often we just don’t think. “Everyone can play a part in reducing waste, whether by not purchasing more food than necessary in your weekly shopping or by asking restaurants to not include the side dish you won’t eat,” Curtin says.
24. What does the author want to show by telling the arugula story?
A. We pay little attention to food waste. B. We waste food unintentionally at times.
C. We waste more vegetables than meat. D. We have good reasons for wasting food.
25. What is a consequence of food waste according to the test?
A. Moral decline. B. Environmental harm.
C. Energy shortage. D. Worldwide starvation.
26. What does Curtin’s company do?
A. It produces kitchen equipment. B. It turns rotten arugula into clean fuel.
C. It helps local farmers grow fruits. D. It makes meals out of unwanted food.
27. What does Curtin suggest people do?
A. Buy only what is needed. B. Reduce food consumption.
C. Go shopping once a week. D. Eat in restaurants less often.

2022年新高考I卷之C篇
The elderly residents (居民) in care homes in London are being given hens to look after to stop them feeling lonely.
The project was dreamed up by a local charity (慈善组织) to reduce loneliness and improve elderly people’s wellbeing, It is also being used to help patients suffering dementia, a serious illness of the mind. Staff in care homes have reported a reduction in the use of medicine where hens are in use.
Among those taking part in the project is 80-year-old Ruth Xavier. She said: “I used to keep hens when I was younger and had to prepare their breakfast each morning before I went to school. ”
“I like the project a lot. I am down there in my wheelchair in the morning letting the hens out and down there again at night to see they’ve gone to bed.”
“It’s good to have a different focus. People have been bringing their children in to see the hens and residents come and sit outside to watch them. I’m enjoying the creative activities, and it feels great to have done something useful.”
There are now 700 elderly people looking after hens in 20 care homes in the North East, and the charity has been given financial support to roll it out countrywide.
Wendy Wilson, extra care manager at 60 Penfold Street, one of the first to embark on the project, said: “Residents really welcome the idea of the project and the creative sessions. We are looking forward to the benefits and fun the project can bring to people here.”
Lynn Lewis, director of Notting Hill Pathways, said: “We are happy to be taking part in the project. It will really help connect our residents through a shared interest and creative activities.”
28. What is the purpose of the project?
A. To ensure harmony in care homes. B. To provide part-time jobs for the aged.
C. To raise money for medical research. D. To promote the elderly people’s welfare.
29. How has the project affected Ruth Xavier?
A. She has learned new life skills. B. She has gained a sense of achievement.
C. She has recovered her memory. D. She has developed a strong personality.

2022年新高考I卷之D篇
Human speech contains more than 2,000 different sounds, from the common “m” and “a” to the rare clicks of some southern African languages. But why are certain sounds more common than others? A ground-breaking, five-year study shows that diet-related changes in human bite led to new speech sounds that are now found in half the world’s languages.
More than 30 years ago, the scholar Charles Hockett noted that speech sounds called labiodentals, such as “f” and “v”, were more common in the languages of societies that ate softer foods. Now a team of researchers led by Damián Blasi at the University of Zurich, Switzerland, has found how and why this trend arose.
They discovered that the upper and lower front teeth of ancient human adults were aligned (对齐), making it hard to produce labiodentals, which are formed by touching the lower lip to the upper teeth. Later, our jaws changed to an overbite structure (结构), making it easier to produce such sounds.
The team showed that this change in bite was connected with the development of agriculture in the Neolithic period. Food became easier to chew at this point. The jawbone didn’t have to do as much work and so didn’t grow to be so large.
Analyses of a language database also confirmed that there was a global change in the sound of world languages after the Neolithic age, with the use of “f” and “v” increasing remarkably during the last few thousand years. These sounds are still not found in the languages of many hunter-gatherer people today.
This research overturns the popular view that all human speech sounds were present when human beings evolved around 300,000 years ago. ”The set of speech sounds we use has not necessarily remained stable since the appearance of human beings, but rather the huge variety of speech sounds that we find today is the product of a complex interplay of things like biological change and cultural evolution,“ said Steven Moran, a member of the research team.
32. Which aspect of the human speech sound does Damián Blasi’s research focus on?
A. Its variety. B. Its distribution. C. Its quantity. D. Its development.
33. Why was it difficult for ancient human adults to produce labiodentals?
A. They had fewer upper teeth than lower teeth.
B. They could not open and close their lips easily.
C. Their jaws were not conveniently structured.
D. Their lower front teeth were not large enough.
34. What is paragraph 5 mainly about?
A. Supporting evidence for the research results.
B. Potential application of the research findings.
C. A further explanation of the research methods.
D. A reasonable doubt about the research process.
35. What does Steven Moran say about the set of human speech sounds?
A. It is key to effective communication. B. It contributes much to cultural diversity.
C. It is a complex and dynamic system. D. It drives the evolution of human beings.

Over the last seven years, most states have banned texting by drivers, and public service campaigns have tried a wide range of methods to persuade people to put down their phones when they are behind the wheel.
Yet the problem, by just about any measure, appears to be getting worse. Americans are still texting while driving, as well as using social networks and taking photos. Road accidents, which had fallen for years, are now rising sharply.
That is partly because people are driving more, but Mark Rosekind, the chief of the National Highway Traffic Safety Administration, said distracted（分心）driving was "only increasing, unfortunately. "
"Big change requires big ideas. " he said in a speech last month, referring broadly to the need to improve road safety. So to try to change a distinctly modern behavior, lawmakers and public health experts are reaching back to an old approach: They want to treat distracted driving like drunk driving.
An idea from lawmakers in New York is to give police officers a new device called the Textalyzer. It would work like this: An officer arriving at the scene of a crash could ask for the phones of the drivers and use the Textalyzer to check in the operating system for recent activity. The technology could determine whether a driver had just texted, emailed or done anything else that is not allowed under New York's hands-free driving laws.
"We need something on the books that can change people's behavior,” said Félix W. Ortiz, who pushed for the state's 2001 ban on hand-held devices by drivers. If the Textalyzer bill becomes law, he said, "people are going to be more afraid to put their hands on the cell phone. "
8. Which of the following best describes the ban on drivers' texting in the US?
A. Ineffective. B. Unnecessary.
C. Inconsistent. D. Unfair.
9. What can the Textalyzer help a police officer find out?
A. Where a driver came from. B. Whether a driver used their phone.
C. How fast a driver was going. D. When a driver arrived at the scene.
10. What does the underlined word "something" in the last paragraph refer to?
A. Advice. B. Data. C. Tests. D. Laws.
11. What is a suitable title for the text?
A. To Drive or Not to Drive? Think Before You Start
B. Texting and Driving? Watch Out for the Textalyzer
C. New York Banning Hand-Held Devices by Drivers.
D. The Next Generation Cell Phone: The Textalyzer-

2022年新高考II卷之D篇
As we age, even if we’re healthy, the heart just isn’t as efficient in processing oxygen as it used to be. In most people the first signs show up in their 50s or early 60s. And among people who don’t exercise, the changes can start even sooner.
“Think of a rubber band. In the beginning, it is flexible, but put it in a drawer for 20 years and it will become dry and easily broken,” says Dr. Ben Levine, a heart specialist at the University of Texas. That’s what happens to the heart. Fortunately for those in midlife, Levine is finding that even if you haven’t been an enthusiastic exerciser, getting in shape now may help improve your aging heart.
Levine and his research team selected volunteers aged between 45 and 64 who did not exercise much but were otherwise healthy. Participants were randomly divided into two groups. The first group participated in a program of nonaerobic (无氧) exercise—balance training and weight training—three times a week. The second group did high-intensity aerobic exercise under the guidance of a trainer for four or more days a week. After two years, the second group saw remarkable improvements in heart health.
“We took these 50-year-old hearts and turned the clock back to 30-or 35-year-old hearts,” says Levine. “And the reason they got so much stronger and fitter was that their hearts could now fill a lot better and pump (泵送) a lot more blood during exercise. ” But the hearts of those who participated in less intense exercise didn’t change, he says.
“The sweet spot in life to start exercising, if you haven’t already, is in late middle age when the heart still has flexibility,” Levine says. “We put healthy 70-year-olds through a yearlong exercise training program, and nothing happened to them at all. ”
Dr. Nieca Goldberg, a spokeswoman for the American Heart Association, says Levine’s findings are a great start. But the study was small and needs to be repeated with far larger groups of people to determine exactly which aspects of an exercise routine make the biggest difference.
12. What does Levine want to explain by mentioning the rubber band?
A. The right way of exercising. B. The causes of a heart attack.
C. The difficulty of keeping fit. D. The aging process of the heart.
13. In which aspect were the two groups different in terms of research design?
A. Diet plan. B. Professional background.
C. Exercise type. D. Previous physical condition.
14. What does Levine’s research find?
A. Middle-aged hearts get younger with aerobic exercise.
B. High-intensity exercise is more suitable for the young.
C. It is never too late for people to start taking exercise.
D. The more exercise we do, the stronger our hearts get.
15. What does Dr. Nieca Goldberg suggest?
A. Making use of the findings. B. Interviewing the study participants.
C. Conducting further research. D. Clarifying the purpose of the study.


2022年1月浙江卷之B篇
The United States rose to global power on the strength of its technology, and the lifeblood that technology has long been electricity. By providing long-distance communication and energy, electricity created the modem world. Yet properly understood, the age of electricity is merely the second stage in the age of steam, which began a century earlier.
"It is curious that no one has put together a history of both the steam and electric revolutions." writes Maury Klein in his book The Power Makers, Steam, Electricity, and the Men Invented Modem America. Klein, a noted historian of technology, spins a narrative so lively that at times it reads like a novel.
The story begins in the last years of the 18th century in Scotland, where Watt perfected "the machine that changed the world". Klein writes, "America did not invent the steam engine, but once they grasped its passwords they put it to more uses than anyone else. "
Meanwhile, over the course of 19th century, electricity went from mere curiosity to a basic necessity. Morse invented a code for sending messages over an electromagnetic circuit. Bell then gave the telegraph a voice. Edison perfected an incandescent bulls that brought electric light into the American home.
Most importantly, Edison realized that success depended on mass electrification, which he showed in New York City. With help from Tesla, Westinghouse's firm developed a system using alternating current, which soon became the major forms of power delivery.
To frame his story, Klein creates the character of Ned, a fictional witness to the progress brought about by the steams and electric revolutions in America during one man's lifetime. It's a technique that helps turn a long narrative into an interesting one.
4. What is Klein's understanding of the age of electricity?
A. It is closely linked to the steam age.
B. It began earlier than proper thought.
C. It is a little-studied period of history.
D. It will come to an end sooner or later.
5. What can be inferred about Ned?
A. He was born in New York City. B. He wrote many increasing stories,
C. He created an electricity company. D. He lived mainly in the 19th century.
6. What is the text?
A. A biography. B. A book review. C. A short story. D. A science report.

The benefits of regular exercise are well documented but there’s a new bonus to add to the ever-growing list. New researchers found that middle-aged women who were physically fit could be nearly 90 percent less likely to develop dementia in later life, and as they did, it came on a decade later than less sporty women.
Lead researcher Dr. Helena Horder, of the University of Gothenburg in Sweden, said: "These findings are exciting because it’s possible that improving people's cardiovascular （心血管）fitness in middle age could delay or even prevent them from developing dementia. "
For the study, 191 women with an average age of 50 took a bicycle exercise test until they were exhausted to measure their peak （最大值的） cardiovascular capacity. The average peak workload was measured at 103 watts.
A total of 40 women met the criteria for a high fitness level, or 120 watts or higher. A total of 92 women were in the medium fitness category; and 59 women were in the low fitness category, defined as a peak workload of 80 watts or less, or having their exercise tests stopped because of high blood pressure, chest pain or other cardiovascular problems.
These women were then tested for dementia six times over the following four decades. During that time, 44 of the women developed dementia. Five percent of the highly fit women developed dementia, compared to 25 percent of the women with medium fitness and 32 percent of the women with low fitness.
"However, this study does not show cause and effect between cardiovascular fitness and dementia, it only shows an association. More research is needed to see if improved fitness could have a positive effect on the risk of dementia and also to look at when during a lifetime a high fitness level is most important. " She also admitted that a relatively small number of women were studied, all of whom were form Sweden, so the results might not be applicable to other groups.
7. What is on the ever-growing list mentioned in the first paragraph?
A. Positive effects of doing exercises.
B. Exercises suitable for the middle-aged.
C. Experimental studies on diseases.
D. Advantages of sporty woman over man
8. Why did the researchers ask the woman to do bicycle exercise?
A. To predict their maximum heart rate.
B. To assess their cardiovascular capacity
C. To change their habits of working out
D. To detect their potential health problems
9. What do we know about Dr Horder's study?
A. It aimed to find a cure for dementia.
B. Data collection was a lengthy process.
C. Some participants withdrew from it.
D. The results were far from satisfactory.
10. Which of the following is the best title for the text?
A. More Women Are Exercising to Prevent Dementia
B. Middle-Aged Women Need to Do More Exercise
C. Fit Women Are Less Likely to Develop Dementia
D. Biking Improves Women's Cardiovascular Fitness

When the explorers first set foot upon the continent of North America, the skies and lands were alive with an astonishing variety of wildlife. Native Americans had taken care of these precious natural resources wisely. Unfortunately, it took the explorers and the settlers who followed only a few decades to decimate a large part of these resources. Millions of waterfowl ( 水 禽 ) were killed at the hands of market hunters and a handful of overly ambitious sportsmen. Millions of acres of wetlands were dried to feed and house the ever-increasing populations, greatly reducing waterfowl habitat.
In 1934, with the passage of the Migratory Bird Hunting Stamp Act (Act), an increasingly concerned nation took firm action to stop the destruction of migratory ( 迁徙的) waterfowl and the wetlands so vital to their survival. Under this Act, all waterfowl hunters 16 years of age and over must annually purchase and carry a Federal Duck Stamp. The very first Federal Duck Stamp was designed by J.N. “Ding” Darling, a political cartoonist from Des Moines, lowa, who at that time was appointed by President Franklin Roosevelt as Director of the Bureau of Biological Survey. Hunters willingly pay the stamp price to ensure the survival of our natural resources.
About 98 cents of every duck stamp dollar goes directly into the Migratory Bird Conservation Fund to purchase wetlands and wildlife habitat for inclusion into the National Wildlife Refuge System — a fact that ensures this land will be protected and available for all generations to come. Since 1934, better than half a billion dollars has gone into that Fund to purchase more than 5 million acres of habitat. Little wonder the Federal Duck Stamp Program has been called one of the most successful conservation programs ever initiated.
28. What was a cause of the waterfowl population decline in North America?
A. Loss of wetlands. B. Popularity of water sports.
C. Pollution of rivers. D. Arrival of other wild animals.
29. What does the underlined word “decimate” mean in the first paragraph?
A. Acquire. B. Export.
C. Destroy. D. Distribute.
30. What is a direct result of the Act passed in 1934?
A. The stamp price has gone down. B. The migratory birds have flown away.
C. The hunters have stopped hunting. D. The government has collected money.
31. Which of the following is a suitable title for the text?
A. The Federal Duck Stamp Story B. The National Wildlife Refuge System
C. The Benefits of Saving Waterfowl D. The History of Migratory Bird Hunting

2021年新高考I卷之D篇
Popularization has in some cases changed the original meaning of emotional (情感的) intellingence. Many people now misunderstand emotional intelligence as almost everything desirable in a person's makeup that cannot be measured by an IQ test, such as character, motivation, confidence, mental stability, optimism and “people skills.” Research has shown that emotional skills may contribute to some of these qualities, but most of them move far beyond skill-based emotional intelligence.
We prefer to describe emotional intelligence as a specific set of skills that can be used for either good or bad purposes. The ability to accurately understand how others are feeling may be used by a doctor to find how best to help her patients, while a cheater might use it to control potential victims. Being emotionally intelligent does not necessarily make one a moral person.
Although popular beliefs regarding emotional intelligence run far ahead of what research can reasonably support, the overall effects of the publicity have been more beneficial than harmful. The most positive aspect of this popularization is a new and much needed emphasis (重视) on emotion by employers, educators and others interested in promoting social well-being. The popularization of emotional intelligence has helped both the public and researchers re-evaluate the functionality of emotions and how they serve people adaptively in everyday life.
Although the continuing popular appeal of emotional intelligence is desirable, we hope that such attention will excite a greater interest in the scientific and scholarly study of emotion. It is our hope that in coming decades, advances in science will offer new perspectives (视角) from which to study how people manage their lives. Emotional intelligence, with its focus on both head and heart, may serve to point us in the right direction.
32. What is a common misunderstanding of emotional intelligence?
A. It can be measured by an IQ test. B. It helps to exercise a person’s mind.
C. It includes a set of emotional skills. D. It refers to a person’s positive qualities.
33. Why does the author mention “doctor” and “cheater” in paragraph 2?
A. To explain a rule. B. To clarify a concept.
C. To present a fact. D. To make a prediction.
34. What is the author’s attitude to the popularization of emotional intelligence?
A. Favorable. B. Intolerant.
C. Doubtful. D. Unclear.
35. What does the last paragraph mainly talk about concerning emotional intelligence?
A. Its appeal to the public. B. Expectations for future studies.
C. Its practical application. D. Scientists with new perspectives.

2021年新高考II卷之D篇
An Australian professor is developing a robot to monitor the health of grazing cattle, a development that could bring big changes to a profession that's relied largely on a low-tech approach for decades but is facing a labor shortage.
Salah Sukkarieh, a professor at the University of Sydney, sees robots as necessary given how cattlemen are aging. He is building a four-wheeled robot that will run on solar and electric power. It will use cameras and sensors to monitor the animals. A computer system will analyze the video to determine whether a cow is sick. Radio tags (标签) on the animals will measure temperature changes. The quality of grassland will be tracked by monitoring the shape, color and texture (质地) of grass. That way, cattlemen will know whether they need to move their cattle to another field for nutrition purposes.
Machines have largely taken over planting, watering and harvesting crops such as com and wheat, but the monitoring of cattle has gone through fewer changes.
For Texas cattleman Pete Bonds, it's increasingly difficult to find workers interested in watching cattle. But Bonds doesn't believe a robot is right for the job. Years of experience in the industry - and failed attempts to use technology - have convinced him that the best way to check cattle is with a man on a horse. Bonds, who bought his first cattle almost 50 years ago, still has each of his cowboys inspect 300 or 400 cattle daily and look for signs that an animal is getting sick.
Other cattlemen see more promise in robots. Michael Kelsey Paris, vice president of the Oklahoma Cattlemen's Association, said a robot could be extremely useful given rising concerns about cattle theft. Cattle tend to be kept in remote places and their value has risen, making them appealing targets.
12. What is a problem with the cattle-raising industry?
A. Soil pollution. B. Lack of workers.
C. Aging machines. D. Low profitability.
13. What will Sukkarieh's robot be able to do?
A. Monitor the quality of grass. B. Cure the diseased cattle.
C. Move cattle to another field. D. Predict weather changes.
14. Why does Pete Bonds still hire cowboys to watch cattle?
A. He wants to help them earn a living. B. He thinks men can do the job better.
C. He is inexperienced in using robots. D. He enjoys the traditional way of life.
15. How may robots help with cattle watching according to Michael Kelsey?
A. Increase the value of cattle. B. Bring down the cost of labor.
C. Make the job more appealing. D. Keep cattle from being stolen.

2021年1月浙江卷之B篇
At the start of the 20th century, an American engineer named John Elfreth Watkins made predictions about life today. His predictions about slowing population growth, mobile phones and increasing height were close to the mark. But he was wrong in one prediction: that everybody would walk 10 miles a day.
Today, in Australia, most children on average fall 2, 000 steps short of the physical activity they need to avoid being overweight. In the early 1970s, 40 per cent of children walked to school, while in 2010, it was as low as 15 per cent.
The decline is not because we have all become lazy. Families are pressed for time, many with both parents working to pay for their house, often working hours not of their choosing, living in car-dependent neighborhoods with limited public transport.
The other side of the coin is equally a deprivation: for health and well-being, as well as lost opportunities（机会）for children to get to know their local surroundings. And for parents there are lost opportunities to walk and talk with their young scholar about their day.
Most parents will have eagerly asked their child about their day, only to meet with a “good”, quickly followed by "I'm hungry". This is also my experience as a mother. But somewhere over the daily walk more about my son's day comes out. I hear him making sense of friendship and its limits. This is the unexpected and rare parental opportunity to hear more.
Many primary schools support walking school-bus routes（路线）, with days of regular, parent-accompanied walks. Doing just one of these a few times a week is better than nothing. It can be tough to begin and takes a little planning-running shoes by the front door, lunches made the night before, umbrellas on rainy days and hats on hot ones-but it's certainly worth trying.
41．Why does the author mention Watkins' predictions in the first paragraph?
A．To make comparisons. B．To introduce the topic.
C．To support her argument. D．To provide examples.
42．What has caused the decrease in Australian children's physical activity?
A．Plain laziness. B．Health problems.
C．Lack of time. D．Security concerns.
43．Why does the author find walking with her son worthwhile?
A．She can get relaxed after work. B．She can keep physically fit.
C．She can help with her son's study. D．She can know her son better.

Researchers say they have translated the meaning of gestures that wild chimpanzees (黑猩猩) use to communicate. They say wild chimps communicate 19 specific messages to one another with a "vocabulary" of 66 gestures. The scientists discovered this by following and filming groups of chimps in Uganda, and examining more than 5,000 incidents of these meaningful exchanges.
Dr Catherine Hobaiter, who led the research, said that this was the only form of intentional communication to be recorded in the animal kingdom. Only humans and chimps, she said, had a system of communication where they deliberately sent a message to another group member.
"That's what's so amazing about chimp gestures," she said. "They're the only thing that looks like human language in that respect. ”
Although previous research has shown that apes and monkeys can understand complex information from another animal's call, the animals do not appear to use their voices intentionally to communicate messages. This was a significant difference between calls and gestures, Dr Hobaiter said.
Chimps will check to see if they have the attention of the animal with which they wish to communicate. In one case, a mother presents her foot to her crying baby, signaling:" Climb on me. " The youngster immediately jumps on to its mothers back and they travel off together. "The big message from this study is that there is another species (物种) out there. that is meaningful in its communication, so that's not unique to humans," said Dr Hobaiter.
Dr Susanne Shultz, an evolutionary biologist from the University of Manchester, said the study was praiseworthy in seeking to enrich our knowledge of the evolution of human language. But, she added, the results were "a little disappointing".
"The vagueness of the gesture meanings suggests either that the chimps have little to communicate, or we are still missing a lot of the information contained in their gestures and actions," she said. "Moreover, the meanings seem to not go beyond what other animal convey with non-verbal communication. So, it seems the gulf remains. "
44．What do chimps and humans have in common according to Dr Hobaiter?
A．Memorizing specific words. B．Understanding complex information.
C．Using voices to communicate. D．Communicating messages on purpose.
45．What did Dr Shultz think of the study?
A．It was well designed but poorly conducted.
B．It was a good try but the findings were limited.
C．It was inspiring but the evidence was unreliable.
D．It was a failure but the methods deserved praise.
46．What does the underlined word "gulf" in the last paragraph mean?
A．Difference. B．Conflict. C．Balance. D．Connection.
47．Which of the following is the best title for the text?
A．Chimpanzee behaviour study achieved a breakthrough
B．Chimpanzees developed specific communication skills
C．Chimpanzees: the smartest species in the animal kingdom
D．Chimpanzee language: communication gestures translated

If you ever get the impression that your dog can "tell" whether you look content or annoyed, you may be onto something. Dogs may indeed be able to distinguish between happy and angry human faces, according to a new study
Researchers trained a group of 11 dogs to distinguish between images(图像)of the same person making either a happy or an angry face. During the training stage, each dog was shown only the upper half or the lower half of the person's face. The researchers then tested the dogs' ability to distinguish between human facial expressions by showing them the other half of the person's face on images totally different from the ones used in training. The researchers found that the dogs were able to pick the angry or happy face by touching a picture of it with their noses more often than one would expect by random chance.
The study showed the animals had figured out how to apply what they learned about human faces during training to new faces in the testing stage. "We can rule out that the dogs simply distinguish between the pictures based on a simple cue, such as the sight of teeth," said study author Corsin Muller. "Instead, our results suggest that the successful dogs realized that a smiling mouth means the same thing as smiling eyes, and the same rule applies to an angry mouth having the same meaning as angry eyes."
"With our study, we think we can now confidently conclude that at least some dogs can distinguish human facial expressions," Muller told Live Science.
At this point, it is not clear why dogs seem to be equipped with the ability to recognize different facial expressions in humans. "To us, the most likely explanation appears to be that the basis lies in their living with humans, which gives them a lot of exposure to human facial expressions," and this exposure has provided them with many chances to learn to distinguish between them, Muller said.
8. The new study focused on whether dogs can_________.
A. distinguish shapes B. make sense of human faces
C. feel happy or angry D. communicate with each other
9. What can we learn about the study from paragraph 2?
A. Researchers tested the dogs in random order.
B. Diverse methods were adopted during training.
C. Pictures used in the two stages were different
D. The dogs were photographed before the lest.
10. What is the last paragraph mainly about?
A. A suggestion for future studies. B. A possible reason for the study findings.
C. A major limitation of the study D. An explanation of the research method.

Returning to a book you’ve read many times can feel like drinks with an old friend. There’s a welcome familiarity - but also sometimes a slight suspicion that time has changed you both, and thus the relationship. But books don’t change, people do. And that’s what makes the act of rereading so rich and transformative.
The beauty of rereading lies in the idea that our bond with the work is based on our present mental register. It’s true, the older I get, the more I feel time has wings. But with reading, it’s all about the present. It’s about the now and what one contributes to the now, because reading is a give and take between author and reader. Each has to pull their own weight.
There are three books I reread annually The first, which I take to reading every spring is Emest Hemningway’s A Moveable Feast. Published in 1964, it’s his classic memoir of 1920s Paris. The language is almost intoxicating (令人陶醉的)，an aging writer looking back on an ambitious yet simpler time. Another is Annie Dillard’s Holy the Firm, her poetic 1975 ramble (随笔) about everything and nothing. The third book is Julio Cortazar’s Save Twilight: Selected Poems, because poetry. And because Cortazar.
While I tend to buy a lot of books, these three were given to me as gifs, which might add to the meaning I attach to them. But I imagine that, while money is indeed wonderful and necessary, rereading an author’s work is the highest currency a reader can pay them. The best books are the ones that open further as time passes. But remember, it’s you that has to grow and read and reread in order to better understand your friends.
24. Why does the author like rereading?
A. It evaluates the writer-reader relationship.
B. It’s a window to a whole new world.
C. It’s a substitute for drinking with a friend.
D. It extends the understanding of oneself.
25. What do we know about the book A Moveable Feas!?
A. It’s a brief account of a trip.
B. It’s about Hemingway’s life as a young man.
C. It’s a record of a historic event.
D. It’s about Hemingway’s friends in Paris.
26. What does the underlined word ＂currency＂ in paragraph 4 refer to?
A. Debt
B. Reward.
C Allowance.
D. Face value.
27. What can we infer about the author from the text?
A. He loves poetry.
B. He’s an editor.
C. He’s very ambitious.
D. He teaches reading.

Race walking shares many fitness benefits with running, research shows, while most likely contributing to fewer injuries. It does, however, have its own problem.
Race walkers are conditioned athletes. The longest track and field event at the Summer Olympics is the 50-kilometer race walk, which is about five miles longer than the marathon. But the sport’s rules require that a race walker’s knees stay straight through most of the leg swing and one foot remain in contact (接触) with the ground at all times. It’s this strange form that makes race walking such an attractive activity, however, says Jaclyn Norberg, an assistant professor of exercise science at Salem State University in Salem, Mass.
Like running, race walking is physically demanding, she says, According to most calculations, race walkers moving at a pace of six miles per hour would burn about 800 calories(卡路里) per hour, which is approximately twice as many as they would burn walking, although fewer than running, which would probably burn about 1,000 or more calories per hour.
However, race walking does not pound the body as much as running does, Dr. Norberg says. According to her research, runners hit the ground with as much as four times their body weight per step, while race walkers, who do not leave the ground, create only about 1.4 times their body weight with each step.
As a result, she says, some of the injuries associated with running, such as runner’s knee, are uncommon among race walkers. But the sport’s strange form does place considerable stress on the ankles and hips, so people with a history of such injuries might want to be cautious in adopting the sport. In fact, anyone wishing to try race walking should probably first consult a coach or experienced racer to learn proper technique, she says. It takes some practice.
28. Why are race walkers conditioned athletes?
A. They must run long distances.
B. They are qualified for the marathon.
C. They have to follow special rules.
D. They are good at swinging their legs.
29. What advantage does race walking have over running?
A. It’s more popular at the Olympics.
B. It’s less challenging physically.
C. It’s more effective in body building.
D. It’s less likely to cause knee injuries.
30. What is Dr. Norberg’s suggestion for someone trying race walking?
A. Getting experts’ opinions.
B. Having a medical checkup.
C. Hiring an experienced coach.
D. Doing regular exercises.
31. Which word best describes the author’s attitude to race walking?
A. Skeptical. B. Objective.
C. Tolerant. D. Conservative.

The connection between people and plants has long been the subject of scientific research. Recent studies have found positive effects. A study conducted in Youngstown，Ohio，for example, discovered that greener areas of the city experienced less crime. In another，employees were shown to be 15% more productive when their workplaces were decorated with houseplants.
The engineers at the Massachusetts Institute of Technology(MIT)have taken it a step further changing the actual composition of plants in order to get them to perform diverse，even unusual functions. These include plants that have sensors printed onto their leaves to show when they’re short of water and a plant that can detect harmful chemicals in groundwater. ＂We’re thinking about how we can engineer plants to replace functions of the things that we use every day,＂explained Michael Strano, a professor of chemical engineering at MIT.
One of his latest projects has been to make plants grow(发光)in experiments using some common vegetables. Strano’s team found that they could create a faint light for three-and-a-half hours. The light，about one-thousandth of the amount needed to read by，is just a start. The technology, Strano said, could one day be used to light the rooms or even to turn tree into self-powered street lamps.
in the future，the team hopes to develop a version of the technology that can be sprayed onto plant leaves in a one-off treatment that would last the plant’s lifetime. The engineers are also trying to develop an on and off＂switch＂where the glow would fade when exposed to daylight.
Lighting accounts for about 7% of the total electricity consumed in the US. Since lighting is often far removed from the power source(电源)-such as the distance from a power plant to street lamps on a remote highway-a lot of energy is lost during transmission(传输).
Glowing plants could reduce this distance and therefore help save energy.
32. What is the first paragraph mainly about?
A. A new study of different plants.
B. A big fall in crime rates.
C. Employees from various workplaces.
D. Benefits from green plants.
33. What is the function of the sensors printed on plant leaves by MIT engineer?
A. To detect plants’ lack of water
B. To change compositions of plants
C. To make the life of plants longer.
D. To test chemicals in plants.
34. What can we expect of the glowing plants in the future?
A. They will speed up energy production.
B. They may transmit electricity to the home.
C. They might help reduce energy consumption.
D. They could take the place of power plants.
35. Which of the following can be the best title for the text?
A. Can we grow more glowing plants?
B. How do we live with glowing plants?
C. Could glowing plants replace lamps?
D. How are glowing plants made pollution-free?

Some parents will buy any high-tech toy if they think it will help their child, but researchers said puzzles help children with math-related skills.
Psychologist Susan Levine, an expert on mathematics development in young children the University of Chicago, found children who play with puzzles between ages 2 and 4 later develop better spatial skills. Puzzle play was found to be a significant predictor of cognition(认知) after controlling for differences in parents’ income, education and the amount of parent talk, Levine said.
The researchers analyzed video recordings of 53 child-parent pairs during everyday activities at home and found children who play with puzzles between 26 and 46 months of age have better spatial skills when assessed at 54 months of age.
“The children who played with puzzles performed better than those who did not, on tasks that assessed their ability to rotate(旋转)and translate shapes,” Levine said in a statement.
The parents were asked to interact with their children as they normally would, and about half of children in the study played with puzzles at one time. Higher-income parents tended to have children play with puzzles more frequently, and both boys and girls who played with puzzles had better spatial skills. However, boys tended to play with more complex puzzles than girls, and the parents of boys provided more spatial language and were more active during puzzle play than parents of girls.
The findings were published in the journal Developmental Science.
24. In which aspect do children benefit from puzzle play?
A. Building confidence. B. Developing spatial skills.
C. Learning self-control. D. Gaining high-tech knowledge.
25. What did Levine take into consideration when designing her experiment？
A. Parents’ age. B. Children’s imagination.
C. Parents’ education. D. Child-parent relationship.
26. How do boy differ from girls in puzzle play?
A. They play with puzzles more often.
B. They tend to talk less during the game.
C. They prefer to use more spatial language.
D. They are likely to play with tougher puzzles.
27. What is the text mainly about?

When you were trying to figure out what to buy for the environmentalist on your holiday list, fur probably didn’t cross your mind. But some ecologists and fashion (时装)enthusiasts are trying to bring back the market for fur made from nutria(海狸鼠).
Unusual fashion shows in New Orleans and Brooklyn have(showcased)nutria fur made into clothes in different styles. “It sounds crazy to talk about guilt-free fur-unless you understand that the nutria are destroying vast wetlands every year”, says Cree McCree, project director of Righteous Fur.
Scientists in Louisiana were so concerned that they decided to pay hunters $5 a tail. Some of the fur ends up in the fashion shows like the one in Brooklyn last month.
Nutria were brought there from Argentina by fur farmers and let go into the wild. “The ecosystem down there can’t handle this non-native species(物种).It’s destroying the environment. It’s them or us.” says Michael Massimi, an expert in this field.
The fur trade kept nutria check for decades，but when the market for nutria collapsed in the late 1980s，the cat-sized animals multiplied like crazy.
Biologist Edmond Mouton runs the nutria control program for Louisiana. He says it’s not easy to convince people that nutria fur is green, but he has no doubt about it. Hunters bring in more than 300,000 nutria tails a year, so part of Mouton’s job these days is trying to promote fur.
Then there’s Righteous Fur and its unusual fashion. Morgan says，”To give people a guilt-free option that they can wear without someone throwing paint on them-1 think that’s going to be a massive thing, at least here in New York.” Designer Jennifer Anderson admits it took her a while to come around to the opinion that using nutria fur for her creations is morally acceptable. She trying to come up with a lable to attach to nutria fashions to show it is eco-friendly.
28. What is the purpose of the fashion shows in New Orleans and Brooklyn?
A. To promote guilt-free fur.
B. To expand the fashion market.
C. To introduce a new brand.
D. To celebrate a winter holiday.
29. Why are scientists concerned about nutria?
A. Nutria damage the ecosystem seriously.
B. Nutria are an endangered species.
C. Nutria hurt local cat-sized animals.
D. Nutria are illegally hunted.
30. What does the underlined word “collapsed” in paragraph 5 probably mean?
A. Boomed. B. Became mature. C. Remained stable. D. Crashed.
31. What can we infer abouf wearing fur in New York according to Morgan?
A. It’s formal. B. It’s risky. C. It’s harmful. D. It’s traditional.

I have a special place in my heart for libraries. I have for as long as I can remember. I was always an enthusiastic reader, sometimes reading up to three books a day as a child. Stories were like air to me and while other kids played ball or went to parties, I lived out adventures through the books I checked out from the library.
My first job was working at the Ukiah Library when I was 16 years old .It was a dream job and I did everything from shelving books to reading to the children for story time.
As I grew older and became a mother, the library took on a new place and an added meaning in my life. I had several children and books were our main source(来源) of entertainment. It was a big deal for us to load up and go to the local library, where my kids could pick out books to read or books they wanted me to read to them.
I always read ,using different voices ,as though I were acting out the stories with my voice and they loved it !It was a special time to bond with my children and it filled them with the wonderment of books .
Now, I see my children taking their children to the library and I love that the excitement of going to the library lives on form generation to generation.
As a novelist, I’ve found a new relationship with libraries. I encourage readers to go to their local library when they can’t afford to purchase a book. I see libraries as a safe haven(避风港) for readers and writers, a bridge that helps put together a reader with a book. Libraries, in their own way, help fight book piracy(盗版行为) and 1 think all writers should support libraries in a significant way when they can. Encourage readers to use the library. Share library announcements on your social media. Frequent them and talk about them when you can.
32. Which word best describes the author’s relationship with books as a child?
A. Cooperative. B. Uneasy. C. Inseparable. D. Casual.

We are the products of evolution, and not just evolution that occurred billions of years ago. As scientists look deeper into our genes (基因), they are finding examples of human evolution in just the past few thousand years. People in Ethiopian highlands have adapted to living at high altitudes. Cattle -raising people in East Africa and northern Europe have gained a mutation (突变) that helps them digest milk as adults.
On Thursday in an article published in Cell, a team of researchers reported a new kind of adaptation - not to air or to food, but to the ocean. A group of sea-dwelling people in Southeast Asia have evolved into better divers. The Bajau, as these people are known, number in the hundreds of thousands in Indonesia, Malaysia and the Philippines. They have traditionally lived on houseboats; in recent times, they’ve also built houses on stilts (支柱) in coastal waters. “They are simply a stranger to the land,” said Redney C. Jubilado, a University of Hawaii researcher who studies the Bajau.
Dr. Jubilado first met the Bajau while growing up on Samal Island in the Philippines. They made a living as divers, spearfishing or harvesting shellfish. “We were so amazed that they could stay underwater much longer than us local islanders,” Dr. Jubilado said. “I could see them actually walking under the sea.”
In201, Melissa Ilardo, then a graduate student in genetics at the University of Copenhagen, heard about the Bajau. She wondered if centuries of diving could have led to the evolution of physical characteristics that made the task easier for them. “it seemed like the perfect chance for natural selection to act on a population,” said Dr. Ilardo. She also said there were likely a number of other genes that help the Bajau dive.
32. What does the author want to tell us by the examples in paragraph 1?
A. Environmental adaptation of cattle raisers. B. New knowledge of human evolution.
C. Recent findings of human origin. D. Significance of food selection.
33. Where do the Bajau build their houses?
A. In valleys. B. Near rivers. C. On the beach. D. Off the coast.
34. Why was the young Jubilado astonished at the Bajau?
A. They could walk on stilts all day. B. They had a superb way of fishing.
C. They could stay long underwater. D. They lived on both land and water.
35. What can be a suitable title for the text?
A. Bodies Remodeled for a Life at Sea B. Highlanders’ Survival Skills
C. Basic Methods of Genetic Research D. The World’s Best Divers

According to a recent study in the Journal of Consumer Research, both the size and consumption habits of our eating companions can influence our food intake. And contrary to existing research that says you should avoid eating with heavier people who order large portions(份), it's the beanpoles with big appetites you really need to avoid.
To test the effect of social influence on eating habits the researchers conducted two experiments. In the first, 95 undergraduate women were individually invited into a lab to ostensibly(表面上)participate in a study about movie viewership. Before the film began, each woman was asked to help herself to a snack. An actor hired by the researchers grabbed her food first. In her natural state, the actor weighed 105 pounds. But in half the cases she wore a specially designed fat suit which increased her weight to 180 pounds.
Both the fat and thin versions of the actor took a large amount of food. The participants followed suit, taking more food than they normally would have. However, they took significantly more when the actor was thin.
For the second test, in one case the thin actor took two pieces of candy from the snack bowls. In the other case, she took 30 pieces. The results were similar to the first test: the participants followed suit but took significantly more candy when the thin actor took 30 pieces.
The tests show that the social environment is extremely influential when we're making decisions. If this fellow participant is going to eat more, so will I. Call it the “I’ll have what she's having” effect. However, we'll adjust the influence. If an overweight person is having a large portion, I'll hold back a bit because I see the results of his eating habits. But if a thin person eats a lot, I'll follow suit. If he can eat much and keep slim, why can't I?
12. What is the recent study mainly about?
A. Food safety. B. Movie viewership.
C. Consumer demand. D. Eating behavior.
13. What does the underlined word “beanpoles” in paragraph 1 refer to?
A. Big eaters. B. Overweight persons.
C. Picky eaters. D. Tall thin persons.
14. Why did the researchers hire the actor?
A. To see how she would affect the participants.
B. To test if the participants could recognize her.
C. To find out what she would do in the two tests.
D. To study why she could keep her weight down.
15. On what basis do we “adjust the influence” according to the last paragraph?
A. How hungry we are. B. How slim we want to be.
C. How we perceive others. D. How we feel about the food.

I am an active playgoer and play-reader, and perhaps my best reason for editing this book is a hope of sharing my enthusiasm for the theater with others. To do this I have searched through dozens of plays to find the ones that I think best show the power and purpose of the short play.
Each play has a theme or central idea which the playwright(剧作家) hopes to get across through dialogue and action. A few characters are used to create a single impression growing out of the theme. It is not my intention to point out the central theme of each of the plays in this collection, for that would, indeed, ruin the pleasure of reading, discussing, and thinking about the plays and the effectiveness of the playwright. However, a variety of types is represented here. These include comedy, satire, poignant drama, historical and regional drama. To show the versatility(多面性) of the short play, I have included a guidance play, a radio play and a television play.
Among the writers of the plays in this collection, Paul Green, Susan Glaspell, Maxwell Anderson, Thornton Wilder, William Saroyan, and Tennessee Williams have all received Pulitzer Prizes for their contributions to the theater. More information about the playwrights will be found at the end of this book.
To get the most out of reading these plays, try to picture the play on stage, with you, the reader, in the audience. The houselights dim(变暗). The curtains are about to open, and in a few minutes the action and dialogue will tell you the story.
21. What do we know about the author from the first paragraph?
A. He has written dozens of plays. B. He has a deep love for the theater.
C. He is a professional stage actor. D. He likes reading short plays to others.
22. What does the author avoid doing in his work?
A. Stating the plays’ central ideas. B. Selecting works by famous playwrights.
C Including various types of plays. D. Offering information on the playwrights.
23. What does the author suggest readers do while reading the plays?
A. Control their feelings. B. Apply their acting skills.
C. Use their imagination. D. Keep their audience in mind.
24. What is this text?
A. A short story. B. An introduction to a book.
C A play review. D. An advertisement for a theater.

The traffic signals along Factoria Boulevard in Bellevue, Washington, generally don't flash the same length of green twice in a row, especially at rush hour. At 9:30am, the full red/yellow/green signal cycle might be 140 seconds. By 9:33am, a burst of additional traffic might push it to 145 seconds. Less traffic at 9:37am could push it down to 135. Just like the traffic itself, the timing of the signals changes.
That is by design. Bellevue, a fast-growing city just east of Seattle, uses a system that is gaining popularity around the US: intersection(十字路口) signals that can adjust in real time to traffic conditions. These lights, known as adaptive signals, have led to significant declines in both the trouble and cost of travels between work and home.
“Adaptive signals can make sure that the traffic demand that is there is being addressed, ” says Alex Stevanovic, a researcher at Florida Atlantic University.
For all of Bellevue’s success, adaptive signals are not a cure-all for jammed roadways. Kevin Balke, a research engineer at the Texas A&M University Transportation Institute, says that while smart lights can be particularly beneficial for some cities, others are so jammed that only a sharp reduction in the number of cars on the road will make a meaningful difference. “It’s not going to fix everything, but adaptive signals have some benefits for smaller cities,” he says.
In Bellevue, the switch to adaptive signals has been a lesson in the value of welcoming new approaches. In the past, there was often an automatic reaction to increased traffic: just widen the roads, says Mark Poch, the Bellevue Transportation Department’s traffic engineering manager. Now he hopes that other cities will consider making their streets run smarter instead of just making them bigger.
25. What does the underlined word “that” in paragraph 2 refer to?
A. Increased length of green lights. B. Shortened traffic signal cycle.
C. Flexible timing of traffic signals. D. Smooth traffic flow on the road.
26. What does Kevin Balke say about adaptive signals?
A. They work better on broad roads.
B. They should be used in other cities.
C. They have greatly reduced traffic on the road.
D. They are less helpful in cities seriously jammed.
27. What can we learn from Bellevue’s success?
A. It is rewarding to try new things. B. The old methods still work today.
C. I pays to put theory into practice. D. The simplest way is the best way.

Challenging work that requires lots of analytical thinking, planning and other managerial skills might help your brain stay sharp as you age, a study published Wednesday in the journal Neurology suggests.
Researchers from the University of Leipzig in Germany gathered more than 1, 000 retired workers who were over age 75 and assessed the volunteers’ memory and thinking skills through a battery of tests. Then, for eight years, the scientists asked the same group to come back to the lab every 18 months to take the same sorts of tests.
Those who had held mentally stimulating(刺激), demanding jobs before retirement tended to do the best on the tests. And they tended to lose cognitive(认知) function at a much slower rate than those with the least mentally challenging jobs. The results held true even after the scientists accounted for the participants’ overall health status.
“This works just like physical exercise, ” says Francisca Then, who led the study. “After a long run, you may feel like you’re in pain, you may feel tired. But it makes you fit. After a long day at work-sure, you will feel tired, but it can help your brain stay healthy. ”
It's not just corporate jobs, or even paid work that can help keep your brain fit, Then points out. A waiter’s job, for example, that requires multitasking, teamwork and decision-making could be just as stimulating as any high-level office work. And “running a family household requires high-level planning and coordinating(协调), ” she says. “You have to organize the activities of the children and take care of the bills and groceries. ”
Of course, our brains can decline as we grow older for lots of reasons-including other environmental influences or genetic factors. Still, continuing to challenge yourself mentally and keeping your mind busy can only help.
28. Why did the scientists ask the volunteers to take the tests?
A. To assess their health status. B. To evaluate their work habits.
C. To analyze their personality. D. To measure their mental ability.
29. How does Francisca Then explain her findings in paragraph 4?
A. By using an expert’s words. B. By making a comparison.
C. By referring to another study. D. By introducing a concept.
30. Which of the following is the best title for the text?
A. Retired Workers Can Pick Up New Skills
B. Old People Should Take Challenging Jobs
C. Your Tough Job Might Help Keep You Sharp
D. Cognitive Function May Decline As You Age

Milwaukee, Wisconsin, is road testing a new way to keep winter roads ice-free – by spreading on them cheese brine, the salty liquid used to make soft cheese, like mozzarella.
Wisconsin, also called "America's Dairyland," is famous for its cheese. The state produced 2.8 billion pounds of cheese last year! a result, there was a lot of leftover cheese brine. Disposing of(处置)the brine can be expensive. So what should cheese makers do with the waste?
Normally, towns use rock salt to de-ice streets. The salt lowers waters' freezing point, causing ice to melt(融化). But using cheese brine could help both cheese producers and cities save money, while keeping roads safe. Cheese brine has salt in it, which, like the rock salt, helps lower water's freezing point.
In addition to saving money, cheese brine could also be a more environment-friendly option. Many people suspect that all the rock salt used every winter is harming the environment.
Rock salt is made of sodium chloride, the sane con-pound (化合物)in ordinary table salt. Sounds harmless, right? But while you probably add only a small amount of salt to your food, road crews spread about 20 million tons of salt on U.S. Roads every year!
The chemical washes off roads and goes into the ground. There it can pollute drinking water, harm plants. and eat away soil. By spreading cheese brine on streets before adding a layer of rock salt, Milwaukee may be able to cut its rock salt use by 30 percent.
Cheese brine has a downside too – a shell similar to that of bad milk. "I don't really mind it," Emil Norby told Modern Farmer magazine. He works for one of Wisconsin's county highway commissions and came up with the idea of using cheese brine. "Our roads smell like Wisconsin!" he said.
24. Why can cheese brine help keep winter roads ice-free?
A. It is soft. B. It contains salt. C. It is warm. D. It has milk in it.
25. What is a benefit of using cheese urine on roads?
A. Improving air quality. B. Increasing sales of rock salt.
C. Reducing water pollution. D. Saving the cheese industry.
26. Milwaukee's new way to de-ice streets may be an example of_______________.
A. barking up the wrong tree B. putting the cart before the horse
C. robbing Peter to pay Paul D. killing two birds with one stone

Today's world is not an easy adjustment for young adults. Key skill set for success is persistence (毅力), a characteristic that researchers say is heavily influenced by fathers. Researchers from Brigham Young University discovered that fathers are in a unique position to help their adolescent children learn persistence.
BYU professors Laura Padilla-Walker and Randal Day arrived at these findings after following 325 American families over several years. And over time，the persistence gained through fathers led to higher achievement in school.
"There are relatively few studies that stress the unique role of fathers，"Padilla-Walker said. "This research also helps to prove that characteristics such as persistence-which can be taught-are key to a child's life success.”
Researchers determined that dads need to practice an "authoritative" parenting style. Authoritative parenting is not authoritarian:rigid，demanding or controlling. Rather，an authoritative parenting style includes some of the following characteristics:children feel warmth and love from their father；responsibility and the reasons behind rules are stressed children are given an appropriate level of autonomy(自主权).
In the study，about 52 percent of the dads exhibited above-average levels of authoritative parenting. A key finding is that over time，children raised by an authoritative father were significantly more likely to develop persistence，which leads to better outcomes in school.
This particular study examined 11 to 14-year-olds living in two-parent homes. Yet the researchers suggest that single parents still may play a role in teaching the benefits of persistence，which is an avenue of future research.
27. What is special about the BYU professors' study?
A. It centered on fathers' role in parenting.
B. It was based on a number of large families.
C. It analyzed different kinds of parenting styles.
D. It aimed to improve kids' achievement in school.
28. What would an authoritative father do when raising his children?
A. Ignore their demands. B. Make decisions for them.
C. Control their behaviors. D. Explain the rules to them.
29. Which group can be a focus of future studies according to the researchers?
A. Single parents.
B. Children aged from 11 to 14.
