A
It is the season for long lines and frayed nerves. Here’s how to deal.
Lighten up
Do yourself a favor and ship your presents. Nearly every U.S. airline charges a fee to check a bag, so shipping gifts is now cheaper and more convenient than carrying them in your luggage.
Weigh your options
Now knowing what you’re going to pay for your luggage is annoying. So calculate your overweight-luggage fees at home. You can find the fees out in advance by visiting new site Luggage Limits, which provides the latest information on more than 90 airlines.
Leave amateurs in the dust
Trust us and get to the airport an extra half-hour early. The check-in and security lines are filled with inexperienced fliers, and it’s a hard walking. Plus, if you decide to cut it close, you may not get onto the flight at all. To reduce costs, airlines have reduced on flights and routes. The remaining flights are more likely to be oversold, especially on busy travel days. Fliers who check in early are the least likely to get bumped from oversold flights.
Take it public
The rates for renting a car at the airport have more than doubled over the past year because rental lot inventories (财产) have increased dramatically. True, renting at the airport is convenient, but it’s just not worth it anymore. Unless you really need a car, take public transportation, hop a cab, or beg a friend to pick you up at the airport instead.
Say no to bumper cars
Tell the people picking you up to avoid parking their car. They can hang out in their car for free while waiting to get a call from you when you land. Many airports, including JFK and LAX, now feature this sensible choice.
1. Airlines have reduced flights to .
A. lower the cost B. deal with crisis
C. reduce the time for leave D. provide more job chances
2. We can learn from the passage that .
A. many airports like JFK provides free parking service
B. shipping presents is more expensive than carrying them in luggage
C. taking a cab at the airport is less expensive than renting a car
D. Luggage Limits can give a discount on overweight luggage fees
3. What’s the best title for the passage?
A. Cars at the Airport B. Good Seasons for Flight
C. How to Board a Flight D. 5 Ways to Survive a Holiday Flight.
B
It was once common to regard Britain as a society with class distinction. Each class had unique characteristics.
In recent years, many writers have begun to speak the ‘decline of class’ and ‘classless society’ in Britain. And in modern day consumer society everyone is considered to be middle class.
But pronouncing the death of class is too early. A recent wide-ranging society of public opinion found 90 percent of people still placing themselves in particular class; 73 percent agreed that class was still a vital part of British society; and 52 percent thought there were still sharp class differences. Thus, class may not be culturally and politically obvious, yet it remains an important part of British society. Britain seems to have a love of stratification.
One unchanging aspect of a British person's class position is accent. The words a person speaks tell her or his class. A study of British accents during 1970s found that a voice sounding like a BBC newsreader was viewed as the most attractive voice. Most people said this accent sounded ‘educated’
and ‘soft’. The accents placed at the bottom in this study, on the other hand, were regional city accents. These accents were seen as ‘common’ and ‘ugly’. However, a similar study of British accents in the US turned these results upside down and placed some regional accents as the most attractive and BBC English as the least. This suggests that British attitudes towards accent have deep roots and are based on class prejudice.
In recent years, however, young upper middle-class people in London, have begun to adopt some regional accents, in order to hide their class origins. This is an indication of class becoming unnoticed. However, the 1995 pop song ‘Common People’ puts forward the view that though a middle-class person may ‘want to live like common people’ they can never appreciate the reality of a working-class life.
4. A recent study of public opinion shows that in modern Britain . A．people regard themselves socially different
B. most people belong to middle class
C. it is easy to recognize a person’s class
D. it is time to end class distinction
5. The word “stratification” underlined in Paragraph 3 is closest in meaning to . A．variety B．qualification C．authority D．division
6. British attitudes towards accent .
A. are based on regional status B．have a long tradition
C．are shared by the Americans D．have changed in recent years
7. What is the main idea of the passage?
A. The middle class is expanding. B．A person’s accent reflects his class. C．Class is a key part of British society D．Each class has unique characteristics.
C
On September 11, 2001, I was in the second week of the new school year with my senior English class at T. C. Williams High School just a few miles south of the Pentagon.
Suddenly that morning, a colleague who grew up in New York, opened the classroom door and said, "Turn on the TV the World Trade Center has just been hit by a plane." I've always believed in never letting school get in the way of my students' education. I switched on the TV in front of the room, and my students and I listened to the announcers making a guess about what had happened
—only to see the second plane hit. At first, the sight of the towers burning didn't seem to have much more immediacy than a TV action movie. Soon, however, things in that classroom would get far too immediate.
In what seemed like about a half-hour after the second plane hit, we heard a loud explosion outside the school. Several students were shocked and I told them not to worry, saying that "it was just a car backfiring". A moment later a boy sitting near the windows said, "That's no car; look at that black smoke." We could see an enormous plume of smoke rising in the distance, but didn't know where it was coming from until, a few seconds later, the NBC reporter stationed at the Pentagon broke into the New York coverage to say that he felt the ground shake beneath him as he heard an explosion—obviously the same one that had just surprised my students. It was several minutes before it was announced that the explosion came from a plane hitting the Pentagon.
At that point, a boy, a football player suddenly came undone and had to be comforted by the girls in the class. His mom worked in the Pentagon, and when he tried to get her on his cellphone he could not get through.
Reports vastly overestimated the number of deaths in the Pentagon. Some reports were estimating over 800 dead when the actual death toll at the Pentagon was 125.
8. The author was working as on September 11, 200.
A. a security guard B. an officer in the Pentagon
C. a TV reporter for NBC D. a teacher in a school
9. What can be inferred from the second paragraph?
A. Another plane hit the Pentagon before the author turned on the TV.
B. The author believed that there exists something deserving attention besides school.
C. The author's colleague forced him and his students to watch the TV report.
D. The author thought the hit got in the way of his students' education.
10. Which of the following is TRUE based on the third paragraph?
A. The loud explosion was caused by the plane hitting the Pentagon.
B. The author tried to comfort his students by telling them the truth.
C. The author realized the Pentagon was hit immediately he heard the loud explosion.
D. The boy sitting near the windows witnessed the hit.
11. What does the author mean by mentioning the football player suddenly came undone?
A. The football player was terrified when a car crashed against the school gate.
B. The football player felt at a loss as his mum left without saying good-bye.
C. The football player lost self-control as he was unable to contact his mum.
D. The football player exploded with anger since he was forbidden to use his cell phone.
D
When Omar Yaghi was growing up in Jordan, his neighborhood received water for only about
5 hours once every 2 weeks. If Yaghi wasn’t up at dawn to turn on the taps to store water, his family, their cow, and their garden had to go without. At a meeting last week, Yaghi, now a chemist at the University of California, reported that he and his colleagues have created a solar-powered device that could provide water for millions in water-stressed regions. At its heart is a porous crystalline (多孔晶体) material, known as a metal-organic framework (MOF), which acts like a sponge: It
sucks water vapor out of air, and then releases it as liquid water.
Yaghi and his colleagues first developed a zirconium( 锆 )-based MOF in 2014 that could harvest and release water. But at $160 per kilogram, zirconium is too expensive for massive use. So, last year, his team came up with an alternative called MOF-303, based on aluminum, which costs just $3 per kilogram, but the harvest was only about 0.2 liters per kilogram of MOF per day.
In July 2019, Yaghi reported that his team has designed a new and far more productive water harvester. Supported by a solar panel to power a fan and heater, which speed the cycles, the new device produces up to 1.3 liters of water per kilogram of MOF per day from desert air. Yaghi expects further improvements to increase that number to 8 to 10 liters per day. And his company plans to release a microwave-size device able to provide up to 8 liters per day this fall. The company promises an enlarged version next year that will produce 22,500 liters per day, enough to supply a small village.
However, it needs to be shown that Yaghi’s MOFs can be produced cheaply on a large scale. Each potential commercial MOF needs to prove itself in stability, efficiency, and life span. But if MOFs can pass those tests, they could offer a solution to some of the world’s most pressing problems.
12. Why is Omar Yaghi’s childhood mentioned at the beginning?
A. To show how serious water problem is. B. To lead in the topic.
C. To introduce the chemist. D. To arouse reader’s interest.
13. What is the problem of MOF-303?
A. It costs too much. B. It can’t last long.
C. It is hard to operate. D. It is low in efficiency.
14. According to Yaghi, how much water will a large water harvester produce per day?
A. 1.3 liters. B. 10 liters.
C. 22,500 liters. D. 8 liters.
15. What can be concluded from the last paragraph?
A. Yaghi’s MOFs are in great demand now.
B. Yaghi’s MOFs may help solve water shortage.
C. Yaghi’s MOFs have already entered the market.
D. Mass production of Yaghi’s MOFs is impossible.
第二节 短文选句（共 5 小题；每小题 2 分，满分 10 分）
根据短文内容，从短文后的选项中选出能填入空白处的最佳选项，选项中有两项为多余选项。
Scientists don’t know yet whether cell phones are bad for the brain. 16
In the experiment, the 47 participants may have looked a little strange. Each of them had two Samsung cell phones tied to his or her head—one on each ear. 17 The phone on the right ear played a message for 50 minutes, but the participants couldn’t hear it because the sound was off. After 50 minutes with two phone attached to their heads, the participants were given PET scans. The PET scan is a way to take a three-dimensional picture of how the inside of the body works.
The PET scan showed that the left side of each participant’s brain hadn’t changed from the way it was before the experiment. 18 These right-side brain cells were using almost as much glucose as the brain uses when a person is talking. This suggests that brain cells there were active even without the person hearing or talking anything. This activity, the scientists say, was probably touched off by radiation from the phone.
19 They release different amounts of radiation depending on whether a person is talking or listening, the type of phone, the number of people using phones nearby, and the distance to the nearest cell phone tower. All of these changes make it difficult to collect evidence about any health risks of cell phones, since exposure to radiation can vary.
So for those who don’t want to wait to find out for sure whether cell phones are bad for the brain, there are ways to talk more safely. 20
A. The phone on the left ear was off.
B. So an experiment was done to attempt to find it out.
C. People should avoid having a long conversation by using cell phones.
D. Cell phones do not always give out the same amount of energy.
E. You can have short conversations, use a speakerphone to keep the phone away from your head.
F. The right side of the brain, however, had used more glucose, which provided fuel to brain cells.
G. From the PET scan the differences between the two sides of the brain were observed.

I developed a crush (热爱) on a cute girl I met in a pet store. She led a very 21 lifestyle and we did not have much to talk about. But somehow none of this seemed to 22 . I enjoyed being with her and I felt a sparkle in her presence. And it seemed to me that she enjoyed my 23 as well.
When I learned her birthday was coming up, I decided to ask her out. On the threshold (门槛) of calling her, I sat and looked at the phone for about half an hour. Then I dialed and hung up 24 it rang. I felt like a high school boy, bouncing between 25 anticipation and fear of rejection. A voice from hell kept telling me that she would not like me and that I had a lot of 26 asking
her out. But I felt too enthusiastic about being with her to let the 27 stop me. 28 I got up the nerve to ask her. She thanked me for calling and told me she already had 29 .
I felt shot down. The 30 voice that told me not to call advised me to give up before I was
31 embarrassed. 32 there was more inside of me that wanted to come to 33 . I had feeling for this woman, and I had to express them.
So I bought her a pretty birthday card on which I wrote a 34 note. I walked around the corner to her pet shop. As I approached the door, that same disturbing voice 35 me, "What if she doesn't like you? What if she 36 you?" Feeling vulnerable, I stuffed the 37 under my shirt. I decided that if she showed me 38 of affection, I would give it to her; if she was cool to me, I would leave the card 39 . This way I would not be 40 and would avoid rejection or embarrassment.

Gone are the days 41 people were happy to spend their holiday sitting on a beach. Travelling today is more about searching 42 adventures. As shown in the graphic above, 50 percent of the Americans 43 (survey) would like to swim with wildlife in the ocean during their vacation.
But to make 44 clear, adventure holidays don’t have to be about pushing yourself to your physical limit –things like visiting the South Pole, 45 hiking in a desert. They can be anything “experiential”, such as 46 (go) hunting with indigenous (土著的) people in Australia. Even not booking a hotel but just taking 47 flight to a new place is 48 (adventure) enough. As UK explorer Levison Wood once 49 (write) in The Telegraph, “It’s more the sense of
accepting the unknown and embracing the 50 (uncertain).”

One June, I helped my grandma water the freshly planted flowers around the house. She was so gentle with them no wonder they grew so fast. When all the work were finished, I ran to get my bike to ride for a while. As I was getting on it, however, I noticed there was anything new. I got off and kneel down on the walkway leading to our house. I found a single wild flower coming out of a crack by the walkway, without the water, soil or love.
The surprised new life hit me a lot. Sometimes in my own life, I felt my grow looked like grandma’s flowers, that were loved and cared for. At other times I felt as if I were that wild flower, growing by the walkway quiet and having to grow through the solid concrete. I realized that it doesn’t matter where you grow and it just matters that you grow.

However, it needs to be shown that Yaghi’s MOFs can be produced cheaply on a large scale. Each potential commercial MOF needs to prove itself in stability, efficiency, and life span. But if MOFs can pass those tests, they could offer a solution to some of the world’s most pressing problems.
12. Why is Omar Yaghi’s childhood mentioned at the beginning?
A. To show how serious water problem is. B. To lead in the topic.
C. To introduce the chemist. D. To arouse reader’s interest.
13. What is the problem of MOF-303?
A. It costs too much. B. It can’t last long.
C. It is hard to operate. D. It is low in efficiency.
14. According to Yaghi, how much water will a large water harvester produce per day?
A. 1.3 liters. B. 10 liters.
C. 22,500 liters. D. 8 liters.
15. What can be concluded from the last paragraph?
A. Yaghi’s MOFs are in great demand now.
B. Yaghi’s MOFs may help solve water shortage.
C. Yaghi’s MOFs have already entered the market.

Scientists don’t know yet whether cell phones are bad for the brain. 16
In the experiment, the 47 participants may have looked a little strange. Each of them had two Samsung cell phones tied to his or her head—one on each ear. 17 The phone on the right ear played a message for 50 minutes, but the participants couldn’t hear it because the sound was off. After 50 minutes with two phone attached to their heads, the participants were given PET scans. The PET scan is a way to take a three-dimensional picture of how the inside of the body works.
The PET scan showed that the left side of each participant’s brain hadn’t changed from the way it was before the experiment. 18 These right-side brain cells were using almost as much glucose as the brain uses when a person is talking. This suggests that brain cells there were active even without the person hearing or talking anything. This activity, the scientists say, was probably touched off by radiation from the phone.
19 They release different amounts of radiation depending on whether a person is talking or listening, the type of phone, the number of people using phones nearby, and the distance to the nearest cell phone tower. All of these changes make it difficult to collect evidence about any health risks of cell phones, since exposure to radiation can vary.
So for those who don’t want to wait to find out for sure whether cell phones are bad for the brain, there are ways to talk more safely. 20
A. The phone on the left ear was off.
B. So an experiment was done to attempt to find it out.
C. People should avoid having a long conversation by using cell phones.
D. Cell phones do not always give out the same amount of energy.
E. You can have short conversations, use a speakerphone to keep the phone away from your head.
F. The right side of the brain, however, had used more glucose, which provided fuel to brain cells.
G. From the PET scan the differences between the two sides of the brain were observed.

I developed a crush (热爱) on a cute girl I met in a pet store. She led a very 21 lifestyle and we did not have much to talk about. But somehow none of this seemed to 22 . I enjoyed being with her and I felt a sparkle in her presence. And it seemed to me that she enjoyed my 23 as well.
When I learned her birthday was coming up, I decided to ask her out. On the threshold (门槛) of calling her, I sat and looked at the phone for about half an hour. Then I dialed and hung up 24 it rang. I felt like a high school boy, bouncing between 25 anticipation and fear of rejection. A voice from hell kept telling me that she would not like me and that I had a lot of 26 asking
her out. But I felt too enthusiastic about being with her to let the 27 stop me. 28 I got up the nerve to ask her. She thanked me for calling and told me she already had 29 .
I felt shot down. The 30 voice that told me not to call advised me to give up before I was
31 embarrassed. 32 there was more inside of me that wanted to come to 33 . I had feeling for this woman, and I had to express them.
So I bought her a pretty birthday card on which I wrote a 34 note. I walked around the corner to her pet shop. As I approached the door, that same disturbing voice 35 me, "What if she doesn't like you? What if she 36 you?" Feeling vulnerable, I stuffed the 37 under my shirt. I decided that if she showed me 38 of affection, I would give it to her; if she was cool to me, I would leave the card 39 . This way I would not be 40 and would avoid rejection or embarrassment.

Gone are the days 41 people were happy to spend their holiday sitting on a beach. Travelling today is more about searching 42 adventures. As shown in the graphic above, 50 percent of the Americans 43 (survey) would like to swim with wildlife in the ocean during their vacation.
But to make 44 clear, adventure holidays don’t have to be about pushing yourself to your physical limit –things like visiting the South Pole, 45 hiking in a desert. They can be anything “experiential”, such as 46 (go) hunting with indigenous (土著的) people in Australia. Even not booking a hotel but just taking 47 flight to a new place is 48 (adventure) enough. As UK explorer Levison Wood once 49 (write) in The Telegraph, “It’s more the sense of
accepting the unknown and embracing the 50 (uncertain).”

One June, I helped my grandma water the freshly planted flowers around the house. She was so gentle with them no wonder they grew so fast. When all the work were finished, I ran to get my bike to ride for a while. As I was getting on it, however, I noticed there was anything new. I got off and kneel down on the walkway leading to our house. I found a single wild flower coming out of a crack by the walkway, without the water, soil or love.
The surprised new life hit me a lot. Sometimes in my own life, I felt my grow looked like grandma’s flowers, that were loved and cared for. At other times I felt as if I were that wild flower, growing by the walkway quiet and having to grow through the solid concrete. I realized that it doesn’t matter where you grow and it just matters that you grow.
