As much as 80 percent of premature heart disease is preventable by making specific lifestyle choices.____1____But others may not have crossed your mind. “A small change in your everyday routine can potentially have a big impact in the long run,” says preventive cardiologist Dr. Beth Abramson.
●Get eight hours of sleep.
“When you're not rested, everything that happens in your life is a lot more stressful,” says Dr. Arya Sharma, a professor of medicine at the University of Alberta. If we're sleep deprived, our bodies also have more difficulty controlling blood pressure, inflammation and glucose levels.____2____
●____3____
Doing good for others helps your self-esteem and relieves stress. Research published in Psychosomatic Medicine in 2016 showed that a feeling of purpose in life is linked to a lower likelihood of heart attack and stroke. “We know that loneliness is a risk factor for heart health,” adds Sharma. “Volunteering gets you out of the house and creates a social network.”
●Avoid polluted air.
Exposure to this kind of pollution over time raises your risk of heart disease. Inhaling contaminants formed from chemicals like Sulphur (硫) dioxide, carbon and nitrogen oxides may irritate arteries (动脉) and increase inflammation.____4____Try to get your outdoor exercise far away from highways and industrial districts, and spend more time indoors when the air quality index is poor.
●Eat breakfast.
A recent study in the Journal of the American College of Cardiology found that healthy people who skipped breakfast were almost three times more likely to have heart disease six years later than those who partook in a substantial morning meal. According to Abramson, you need to eat a balanced diet as part of a healthy lifestyle.____5____If you're eating a proper breakfast, you’re less likely to be hungry later and make poor food choices.

Nearly 60% of people report experiencing loneliness at some point in their lives. Loneliness can happen to anyone. It can happen in short bursts throughout someone’s life or become a lasting condition. Lasting loneliness can cause someone to think negatively about themselves and increase their risk for depression and anxiety. Long term, it can disturb someone’s cognition(认知), such as problem solving and concentration. While it’s a journey to get through, you can cope and come out of loneliness.____11____
Acknowledge what you’re feeling
It might seem small, but naming what you’re feeling is one of the most important things you can do when coping with loneliness.____12____You can’t find a solution to something if you don’t know what you’re dealing with. Once you accept that you’re feeling lonely, you can step back and see how it’s impacting your life. Then you can decide what to do next.
Make connections with others
____13____One of the best ways to cope with loneliness would be to be intentional about meeting people and cultivating relationships. How you choose to put yourself out there is entirely up to you. It can be anything —volunteering, joining a class or hanging out with your family.
Use peer(伙伴) support groups
Meeting others is great._______14_______There are various online support groups that will allow you to share experiences and build relationships with people who have similar interests.
Consider therapy(治疗)
There’s no exact cause for loneliness.____15____You sometimes need help with loneliness beyond self-help strategies, and that’s okay. Sometimes, the root problem needs to be addressed in therapy. Working with a therapist through cognitive behavioral therapy will help you challenge negative thinking and direct your thoughts, emotions and actions more constructively. Start looking for the best therapist through your healthcare provider, online resources or local groups. Loneliness can feel incredibly isolating, but you’re not alone.

F．It may take a while to feel comfortable and shake off negative feelings.
G．Actually, the deepest connection comes from people who understand what you’re going through.

Learning how to care for a sad person will help you be there for your loved ones and friends when they are down. However, knowing how to care for a sad person is not something an individual is born with. ____16____ Here are a few tips that will eventually help you lift the spirit of a sad person.
Give a hug. Hugging someone shows your affection and care. ____17____ This can make them feel relaxed and open to you. This can also help them recognize that you are there to help them go through this moment. With no kind and loving words, your actions have already said a lot.
____18____ Now, go on and say some kind words. Words like “I’m here”, “we are in this together”, “you’ll get over this”, “lean on me” and so on, can help a sad person feel better and know that you’re there to take him/her through the sad moment.
Use the right tone of voice. ____19____ They go along with tone to convey a meaning to the listener. To convey your words with faith that would create a positive effect on the sad person, you would need to say it with the right tone of voice.
Listen patiently. People ask lots of questions but they end up paying little attention to getting the feedback (反馈) that they wanted. Don’t be that person. After asking the questions, listen patiently to know what the sad person would appreciate at that time. ____20____

Pets should not be left alone for too long during the day. But our busy lifestyles will sometimes tear us away. ____21____ Here are some tips to keep your pets content.
Cats don’t simply curl up and sleep when you leave. ____22____ If they have a friend or sibling they will create games and comfort one another but if they are alone they will need more stimuli (刺激物). Leaving the TV or radio on can help, and while you work out their favorite channel, you can’t go far wrong with classical music.
____23____ They will keep your cat physically and mentally busy, which will lessen the separation anxiety. Some of the toys are also practical for your home, such as scratching posts to prevent the furniture from being scratched.
It’s not just cats that suffer from separation anxiety. Dogs also dislike being left alone and unfortunately they can’t tell whether it’s been ten minutes or ten hours: the displeasure felt is very similar.
____24____ Background noise from the TV or radio can help them to feel less alone. There is even a dog TV channel designed to create happy and calm thoughts in dogs, showing idyllic scenes of fields, beaches and other dogs.
You can also gradually lengthen the distance and time of your separation until your dogs can be left alone for 20 minutes without showing their usual symptoms of sadness and stress. ____25____

John Myatt is an artist. He may not be the greatest artist in the world, but he is possibly the world’s greatest forger (伪造者). He is able to paint pictures in the style of famous artists like Monet and Matisse.
___26___ This unusual skill got Myatt into a lot of trouble in the 1990s. For many years he taught art at a secondary school, but then he got divorced (离婚) and he gave up his job to spend more time with his children. In order to make some money he started painting pictures in the style of famous artists and selling them.
___27___ He was honest about his work—he wrote his name on the back, and he sold them for ￡150 each. However, one of his customers, John Drewe, started to resell Myatt’s paintings as genuine, original works. Drewe had sold one of Myatt’s paintings for￡25,000. He contacted Myatt and suggested that they go into business together. Myatt agreed. He continued to paint and Drewe sold his paintings to art collectors around the world. ___28___
The amazing thing is that Myatt painted his pictures with decorator’s paint. ___29___ But it soon came to an end. Drewe was divorced too, and his ex-wife found out about the forgeries. She went to the police and they arrested Dewe and Myatt. At their trial Drewe was sent to prison for six years and Myatt for less than one year.
___30___ When he came out he started to produce pictures in the style of famous artists again. But he put his name on the back, as he’d done before he met Drewe. Myatt is now famous and instead of charging￡150 for a painting, he can charge￡40-50,000.
A．It wasn’t illegal.
B．Then he decided to stop copying famous paintings.
C．It was the same paint that people use to paint houses!
D．Myatt only spent four months in prison for good behavior.
E．That’s more than Drewe gave him for his ‘genuine’ paintings!
F．His pictures are so good that experts can’t tell that they are not originals.
G．Between 1986 and 1994 they sold about 200 paintings and made over a million pounds.

The teenage years are probably the most unsettled and stressful years in a person’s life. Teens experience significant physical, emotional, social and cognitive changes. And teens of today face more challenges as they go through more uncertain times of the 21st century. ____31____
As teens experience massive physical, social and emotional changes, the challenges are managing social expectations of ideal body images, developing their identity and finding their place in the world. In the past, a teen who was criticized for his or her larger figure or pimpled (有粉刺的) face, might feel embarrassed and dejected in school. ____32____ Constant comparison and endless posts of picture — perfect images and lives give teens greater pressure to follow current fashion trends. The Wall Street Journal reported that Instagram made body images worse for one in three teenage girls.
____33____ Statistics show that most cases of cyber bullying take place on popular social media sites such as Facebook, Instagram, Snapchats and Twitter, where cyber bullies make emotionally scarring comments. These can be made publicly on a teen’s social media account. ____34____ As a result, cyber bullying can be more threatening than traditional bullying because it can be shared and viewed repeatedly on social media. In this age of social media, it is also important for teens to learn to cultivate positive, and healthy relationships with people.
There have been many discussions about new technologies and ways of working, such as artificial intelligence (AI) and automation, which will impact future jobs. ____35____. Unlike in the past, the situation is different today as AI and automation are causing some jobs to disappear. Teens will have to meet this challenge by adopting an attitude of lifelong learning, and keeping paces with technology.

B．Furthermore, social media has taken bullying to a new level.
C．The future has always been a dreamland for teens to anticipate.

F．Additionally, social media is a strong tool for a teen to defend himself.
G．The challenge for a teen today is preparing for a largely unknown future.

How to accept change in life and embrace it positively
Change is the only constant in life. ____36____ Because whether we want it or not, change is inevitable. It is “change” that makes our life move forward. It’s “change” that makes life exciting and worth living. Let’s see how to stay strong when we face changes in life.
Accept the situation
Changes happen expectedly and unexpectedly. ____37____ But there can be changes that happen so suddenly that you might have to experience painful days and have a tough time coping with them. Give yourself sometime to come to terms with it. You may have to go through a mourning period where you have to experience all kinds of emotions. Let the emotions come out and make space for them. It’s normal to feel sad and a sense of loss when you think about your old life. Seek support and if possible, take a few days off to find your strength. It’s important to learn to deal with the transition phase before you fully start living the new reality.
Embrace the unknown
Most of us are afraid of the unknown and therefore are resistant to change. ____38____ Even if it is for good, we hesitate to accept change because human beings love structure and routine. But I have often experienced in my life that the “unknown” I feared so much was not that scary at all, once I went through it. And that my worries were something that my mind made up. Truth be told, most of the things I worried about didn’t happen anyway. If we are not willing to embrace the unknown, we may miss out on lots of good things that life has kept in store for us.
____39____
One of the reasons change is difficult to accept is because of the range of emotions we feel when we confront change. ____40____ Acknowledge your fears, but stop yourself from being tunnel-visioned. Our mind has away of bringing up possible scenarios and fear them. But I have learned over the years that most of the things we fear don’t happen and usually, something good comes from change. I recently learned how to embrace emotions from one of my spiritual teachers. She would say, “When you feel emotions, give them a name and acknowledge that they have come to ‘visit’.”
A．Acknowledge your fears.
B．Look at how far you have come.
C．The sooner we learn to make peace with this fact, the better.
D．We fear the unknown because anything can happen to us there.
E．Expected or planned changes can buy us sometime for preparation.
F．It’s important to embrace your feelings and accept that they are there.
G．People who have experienced the loss of loved ones often talk about how that experience changed them.

Tears can ruin make-up, bring conversation to a stop, and give you a runny nose. ____41____However, crying is a fact of life, and tears are very useful. Even when you’re not crying, your eyes produce tears. These create a film (薄膜) over the eye’s surface. This film contains a substance that protects your eyes against infection.
Tears reduce stress, but we tend to fight them for all sorts of reasons. “____42____ They’re afraid that once they lose control, they’ll never get it back,” explains psychologist Dorothy Rowe.
Almost any emotion—good or bad, happy or sad—can cause tears. ____43____ Tears help you when you feel you are ready to explode because of very strong feelings. It may explain why people who are afraid to cry often suffer more heart attacks than people who cry more freely.
When some people become very stressed, however, they can’t cry. They may be feeling shock, anger, fear or grief, but they control the emotion. “Everyone has the need to cry,” says psychotherapist (精神治疗医师) Vera Diamond. ____44____ They practice crying so that they can get used to expressing emotion.
____45____ It’s good to hold back tears during a tense business discussion. “But once you are safely behind closed doors, don’t just cry,” Diamond says. She suggests that you act out the whole situation again and be as noisy and angry as you like. It will help you feel better. “And,” she adds, “once your tears have released the stress, you can begin to think of logical ways to deal with the problem.”
Tears are a sign of our ability to feel. You should never be afraid to cry.
A．People worry about showing their emotions.
B．The more you cry, the healthier you will become.
C．Crying is a way that we release built-up emotions.
D．Sometimes patients participate in crying exercises.
E．They can leave you embarrassed and without energy.
F．In certain situation, such as at work, tears are not appropriate.
G．Many people get uncomfortable when others cry in front of them.

In recent years, cotton bags have risen to popularity as an eco-friendly alternative to single-use bags. Many supermarkets have made the change. ___46___
As a study by the Ministry of Environment and Food of Denmark shows, a cotton bag needs to be used 20,000 times to offset (抵消) its overall impact of production on the environment. ___47___ According to this measure, for Venetia Berry, an artist in London who found she had at least 25 cotton bags, she would have to live for more than 1,000 years to offset her current bags.
According to the Circular Laboratory, it requires between 10,000 and 20,000 liters of water to produce one kilogram of cotton. And only 15 percent of the 30 million tons of cotton produced every year actually makes its way to textile (纺织品) warehouses. Even when a cotton bag does make it to a treatment plant, most logos printed on them are not recyclable. ___48___ .
That’s not to say cotton is worse than plastic. They both have disadvantages. ___49___ And plastic bags use fossil fuels that produce greenhouse gases, never biodegrade (生物降解) and block the oceans.
Buffy Reid, of the British knitwear label & Daughter, stopped production of her cotton bags in April 2021. ___50___ For example, British designer Ally Capellino replaced cotton with hemp (麻纤维). In fact, the simplest solution may be the most obvious: Not every product needs a bag.
A．Cotton has dried up rivers for water use.
B．Some companies are turning to other textile solutions.
C．They’re extremely difficult to break down chemically.
D．We are hardly aware of the overuse of plastic in packaging.
E．That is equal to daily use for 54 years for just one cotton bag.
F．However, the production process requires using much more water.
G．But the increase in the use of cotton bags may have created a new problem.

When raindrops fall to the ground in summer, a familiar scent always follows. Many people call this the “smell of rain”. However, rain is made up of odorless (无味的) water. So, where does this smell come from?
___51___ But it actually comes from wet soil. This special odor even has its own name: petrichor (潮土油), which comes from a pair of chemical reactions.
The pleasant smell has long been an interest of scientists since Australian scientists first documented the formation of petrichor in 1964. According to scientists, some plants produce oils during dry periods. ___52___
Yet, it’s the second reaction that creates the most petrichor. It occurs when chemicals produced by bacteria in soil are released. ___53___ These bacteria break down and change into simple chemical compounds, providing nutrition for plants. Meanwhile the process also produces geosmin (土臭素), a compound with a distinct earthy aroma (香味).
Lots of animals are sensitive to geosmin but human beings are extremely sensitive to it. When it rains after a long period of dryness, drops of water hit the ground. Geosmin is then released from the surfaces. ___54___ And it finally gives raindrops their familiar scent. If it rains heavily enough, geosmin will be spread downwind, warning others of coming rain.
___55___ And the next time someone mentions how much they love the smell of rain, you can prove your intelligence by explaining where that smell comes from.
A．And when it rains, these oils are released into the air.
B．The smell of petrichor is quite pleasant to the human nose.
C．There are a group of microorganisms widely found in soils.
D．Rain can refresh the soil specially when it rains heavily.
E．Scientists found the distinctive smell doesn’t come from rain.
F．The pleasant smell always comes into being with the flow of air.
G．It is further spread around its surroundings with the aid of wind and rain.

Making Your Memories Last
“My father wrote me a lovely letter before he died. It is the most cherished thing I own.” Have you ever heard someone say so?
As you all know,your houses, cars, jewels or even money are your financial properties, which are relatively easy to pass along because they are in a physical form. But don’t let your possessions become the only representations of your life. Your thoughts and life journey are equally valuable. ____56____
Studies have shown that kids who know about their family’s past are more empathetic,have better coping skills and higher self-esteem.____57____So how can you turn those feelings, thoughts, and insights into something that can be passed on? These tips can help get you started.
Create a catalogue
Before you begin, check what you’ve got. If you want to pass along family stories or wisdom, list everything available to you, such as photos and letters from your parents.____58____ You could, for example, interview your parents about their lives or write an article about your academic progress.
Make a plan
Once you know what you’ve got and what you need, make a list that details how you’re going to produce what you’re missing and how to record it. ____59____You don’t want the book of your life stories lost in an attic!
____60____
You can’t possibly get everything done at once. By taking active steps and starting with the easiest-to-create projects, you can bring memories to life. For example,you can write a short article about your childhood or film a two-minute video about your wedding day. When you see the results of these smaller projects, you may well be inspired to create more.
A．Take simple steps
B．Get more specific
C．And it’s also significant to consider how to keep it.
D．Then figure out what you still need to add to your collection.
E．For older adults, passing on their life stories helps decrease depression.
F．They become the foundation on which family members build their lives.
G．But they can always get a head start equipped with those precious memories.

Soon you’ll be done with the stresses of high school. You might think college will be a breeze — studying your favorite courses and hanging out with your friends all day. ____61____ Creating good habits can help you settle in faster and make the most of college life. Here are some habits you might need to work on.
•Manage your time. No more sitting in the classroom from dawn till dusk. You’ll have a unique class timetable and more free time. Parents or teachers won’t be around to help plan your schedule. Spend some time working out what study routine and schedules work best for you. ____62____
•____63____College is a crucial time in life for personal development, so make sure you stay on track and always feel positive. Don’t hesitate to reach out for help if you face problems you don’t know how to deal with. Colleges offer many wonderful student services, including academic tutoring, mental health counseling (咨询) and career advice. It’s a great free resource that helps you both in the long and short run. ____64____ This will save you a lot of stress.
•Be kind to yourself. There may be expectations for you or others to do really well at college. If you don’t reach this expectation, you might feel upset. ____65____ You may get stressed in the first semester of college if your grades are lower than expected.

When starting college, most students enjoy a week’s stay on campus before classes actually begin. ___66___ Below are several tips to ease yourself into college life.
Participating in campus welcome activities.
Most universities host welcome events before the academic year officially begins, including freshmen orientations (迎新会), campus picnics, and entertainments like concerts. Participating in such events is a great way to learn about school facilities and understand campus culture: ___67___ What are their favorite classes? What is the history of your university? It can help you observe campus life outside the classroom.
Exploring campus.
Getting to know where essential campus resources are — such as the student advising center, psychological services, and the tutoring center will make your first few weeks on campus a lot easier. Take some time to check out the buildings where your classes will be held. This will prevent you from getting lost in the first few days of classes. ___68___ .
___69___
Starting classes means being in different places at different times, so it’s a great idea to start getting used to that routine right this week. ___70___ Following the planned time will ensure you have enough sleep to get to those early classes and stay wide awake. If you have other daily routines, such as exercising or talking on the phone with family, work those into your day-to-day life before classes start so that you get a better idea of how they fit in with your schedule.
A．Starting a routine.
B．Scheduling your life.
C．What do students do for fitting in?
D．What should you do with that time?
E．What helps you most is to schedule your sleep.
F．What can you do to adapt to the new high school life?
G．It also familiarizes you with how long it takes to get from place to place.

Museums can be overwhelming. With thousands of pieces there, how do you know which to focus on? And once you see a piece you like, how do you interact with it? Here is some advice on how to have a meaningful connection when you look at art.
Get up close and personal.____71____ Therefore, take your time to observe qualities about a work that may not come through on a computer screen. That includes its look and the feel of its surface, the marks made by the brush and the path your eyes take when viewing the work.
Stand back. Next, take a few steps back, stand in the center — and observe what’s happening in the big picture. What’s going on in the piece? ____72____ What are they doing? How are they related?
Look at it from an angle. Then try looking at an artwork from its sides, because you might catch something you might not have seen straight on. If it’s something like The Ambassadors by Holbein at The National Gallery in London, if you stand to the side, you’ll see something that from front on looks very different. ____73____ That’s called anamorphic art.
Move your body. If you’re looking at a painting, you can take a finger to the air and trace the outline of the figure or the movement of the brushstrokes. ____74____ This can help you see and feel what it might be like to make this artwork from the artist’s perspective.
Consider the subject of the art. That can have a profound effect on how you feel about the work-and perhaps you can learn something from it. Take the example of Andrew Wyeth’s famous painting, Christina’s World, which depicts (描绘) a girl with a muscle disease crawling across a field to get to her home in the distance. The painting personifies (体现) determination.____75____
A．So just keep an open mind.
B．What have they gone through?
C．When you stand to the side, it changes.
D．How are the figures in the piece arranged?
E．We have the luxury of seeing the real thing at a museum.
F．When looking at sculptures, try the poses with your body.
G．It can in a way relieve your stress to know we have this inner strength.

Now more than ever, libraries have become a center for community learning. No two libraries are the same. One could be a center of students doing projects, while another could be a center for the homeless and people seeking jobs. ___76___ It used to be an unwelcome place for children, but now it has become a hub(活动中心)for community activity.
Holly Jackson, a library consultant, says that year by year, library checkouts are going up, and activities are well-attended. ___77___ When you arrive, there will be someone there to help you and your children set up library cards, sign up for programs, and show you where the books are.
Jackson advises parents visiting the library when lots of activities are going on, as well as when it is quiet time. ___78___ It helps builds confidence in children to talk to librarians, participate in book selection, and share stories with others.
___79___ When there are a lot of activities, Jackson says some children can feel stressed. But going during quiet times gives children a chance to explore at their own pace and allows you the opportunity to meet different people.
“So often people say. ___80___ Go find out what’s going on,“ says Jackson. It could be for filling out a job application, or just finding a book. ”Go find out what it is and find what is there for you and your family.“
A．However, the library provides more books than you expect.
B．Jackson says all you need to do to visit a library is show up!
C．The activities are what librarians design on purpose to attract readers.
D．Quiet time is also an important time to take your children to the library.
E．Parents can set a good example by using the library themselves as a resource.
F．Still, the focus of a library remains as a place for information and knowledge.
G．I haven’t stepped foot in a library in years because I don’t need to know it anymore.

The idea that red means stop and green means go affects more than just traffic light colors. We have been taught from a young age that red means danger, while green means safety. __81__For something we have to look at every day, why couldn’t they have been prettier colors? You’re about to find out.
Before there were traffic lights for cars, there were traffic signals for trains. At first, railroad companies used red to mean stop, white to mean go and green to mean caution. But train conductors ran into a problem with the color white meaning go — bright white could easily be mistaken for stars at night. ___82___ It has been that way ever since.
___83___ That means that as it travels through the air, it gets diffused (分散) less than other colors, so it can be seen from a greater distance. For example, think about how the light turns red as the sun sets. Even though the human eye is most sensitive to a yellowish-green highlighter color, it can see red from further away. But this could happen by chance. It’s not clear whether that was chosen based on wavelength, contrast against green nature or natural connection of red with things like blood. __84__
Yellow has a shorter wavelength than red but a longer wavelength than green. This means that red is noticeable the furthest away, yellow in the middle and green the least distance away — a helpful advanced warning for needing to slow or stop.
However, believe it or not, yellow was once used to mean stop. Back in the 1900s, some stop signs were yellow because it was too hard to see a red sign in a poorly lit area. __85__ Since yellow can be seen well at all times of the day, school areas, some traffic signs and school buses continue to be painted the color. Keep these safe driving tips in the back of your mind whenever you see a yellow light.
A．Railway companies eventually moved to the color green for go.
B．It could be a mix of all three!
C．But why were those particular colors chosen for traffic lights?
D．Employ these driving rules and know that traffic lights have certainly come a long way.
E．Red is the color with the longest wavelength.

An escape game, is a game in which a team of players discover clues, solve puzzles, and accomplish tasks in one or more rooms in order to accomplish a specific goal in a limited amount of time. The goal is often to escape from the site of the game. ____86____
Keep it simple
For most escape games, even the very challenging ones with very high difficulty ratings, the puzzles and clues are surprisingly simple. They are just cleverly hidden and worded to make them appear difficult to solve. Don’t make things difficult by looking for complex solutions. ____87____
____88____
Sometimes, the escape game creators add a puzzle to confuse players, but this hardly happens. As usual, every puzzle is important and each clue has the potential for revealing the key. Carefully analyze every puzzle you come across. Don’t ignore any, as it may be central to achieving your goal of breaking out. If worse comes to worst, ask for a clue from the game master.
Think like a 4th grader
Escape games can get really challenging. To break out, you need to totally bury yourself in the game. Think outside the box and motivate all your creative juices. Remember when you were a kid and you would think up all these imaginative stories and situations. ____89____. Think like a 4th grader and you’ll find the game more enjoyable and the puzzles easier to solve.
Experiment with use

How to Quiet a Complainer(抱怨者)
Have you ever suffered your mother’s complaints about her aches and pains? Lengthy complaints will ruin the quality of your time together. ____91____ Actually there are some ways to get a complainer to stop without starting an argument.
Change the subject. Some complainers will switch topics if you shift the conversation in a direction that interests them. If your neighbor is complaining about the phone company, tell her about an unexpected call you received from an old friend. If your coworker is complaining about your boss, ask whether he met the new employee. ____92____
Summarize the complaint. If your complainer keeps repeating himself, he may stop if you show that you’re listening. ____93____ Using “I” statements rather than “you” statements show that you’re interested rather than trying to shut the person down.

Try to be honest. When you have things to do, tell the complainer that you must cut the conversation short. ____94____ You can simply be honest, even saying you need to move on so the conversation doesn’t bring you down – especially if it’s someone who’s complained to you many times before.
____95____ When it’s someone very close to you–your partner, sibling, or best friend–who stresses you out with a lot of negativity, it’s important to talk about the problem with an open heart. Otherwise, if you bottle up your feelings and continue listening to repeated complaints, you may grow angry or start avoiding the person.

Popcorn does not refer to the popped kernel alone. ____143____ It was originally grown in Central America and became popular in the U. S. in the mid-1800s. Compared with other snacks at the time, it was super easy to make, and it got easier in 1885 when the mobile steam-powered popcorn maker was invented. In the late 19th century, a large number of independent popcorn suppliers became widely available. ____144____
Since popcorn was cheap to make, it was also cheap to buy, which increased the popularity of this treat during the Great Depression. The Depression increased consumer spending on cheaper luxury items such as popcorn and movies, and the two industries teamed up. ____145____ By the mid-1940s, however, movie theaters began to have their own concession stands (小卖部) in the lobby.

Of course, failing to meet your daily goal can be sad. You might focus on your weaknesses rather than your progress. Another problem is that you might find yourself paying too much attention to the step number rather than how your body feels. ___149___
Therefore, if you’re spending too much time looking at your smartwatch, limit your daily step count to a comfortable level. ___150___ For example, concentrating on your hobbies or socializing with friends can be a great way to keep your mind on other things.

83．空后说“That means that as it travels through the air, it gets diffused (分散) less than other colors, so it can be seen from a greater distance. For example, think about how the light turns red as the sun sets. Even though the human eye is most sensitive to a yellowish-green highlighter color, it can see red from further away.(这意味着当它在空气中传播时，它比其他颜色扩散得更少，所以它可以从更远的地方看到。例如，想想太阳下山时光线是如何变红的。尽管人类的眼睛对黄绿色荧光最敏感，但它可以在更远的地方看到红色。)”，说明本段主要介绍的是红色，E选项“Red is the color with the longest wavelength.(红色是波长最长的颜色。)”描述的是红色，因此符合语境，故选E。
84．空前说“It’s not clear whether that was chosen based on wavelength, contrast against green nature or natural connection of red with things like blood.(目前尚不清楚这种选择是基于波长、与绿色的对比还是与血液等物质的自然联系。)”，既然尚不清楚，那就说明可能这几种都有，B选项“It could be a mix of all three!(它可能是三者的混合！)”说明了空前描述的这几种情况可能都有，因此承接上文，符合语境，故选B。
85．空前说“However, believe it or not, yellow was once used to mean stop. Back in the 1900s, some stop signs were yellow because it was too hard to see a red sign in a poorly lit area.(然而，信不信由你，黄色曾经被用来表示停止。早在20世纪初，一些停车标志是黄色的，因为在光线不足的地区很难看到红色标志。)”，空格处应该解释后来为什么又出现了红色标志，G选项“Eventually, highly reflective materials were developed, and red stop signs were born.(最终，高反射材料被开发出来，红色停车标志诞生了。)”说明了红色停车标志是如何诞生的，因此承接上文，符合语境，故选G。

89．根据空前“Remember when you were a kid and you would think up all these imaginative stories and situations.(记得当你还是个孩子的时候，你会想出所有这些富有想象力的故事和情景。)”与空后的“Think like a 4th grader and you’ll find the game more enjoyable and the puzzles easier to solve.(想像一个四年级的学生，你会发现游戏更有趣，谜题更容易解决。)”并结合本段主题句“Think like a 4th grader(像四年级学生一样思考)”可知，该题应该是与像个4年级孩子一样思考问题，B选项“You need to imagine you to be a 10-year-old child.(你需要想象你是一个10岁的孩子。)”与主题句内容一致，且起到承上启下的作用。故选B项。

140．空格后的句子“You should consider various factors such as if you snore or suffer sleep problems, or if you often have back and neck pain.（你应该考虑各种因素，比如你是否打鼾或有睡眠问题，或者你是否经常背部和颈部疼痛）”是说，你的睡觉姿势可能受各种因素的影响，与个人的具体情况有关，空格处的句子也应该提到相关内容，所以E项“Determining the sleeping position for you is personal preference.（睡姿是个人喜好决定的）”填入空格处，和下文是顺接关系。故选E项。
