Dear John,

I was very happy to receive your e- mail in that you asked me about my life. As a Senior 3 student, I was now working very hard to preparing for the National College Entrance Examination. In class, I listen to the teachers attentively and take notes careful. Out off class, I take an active part in various sport to keep healthy, which, I believe, is very important for my study.

Both my teachers and parents give me many support. With their help and encouragement, I have been made great progress and been able to build up our confidence. I have decided to attend medical university.

Best wishes,

Yours，

Mary

Muzak

The next time you go into a bank, a store, or a supermarket, stop and listen. What do you hear? 1.. It's similar to the music you listen to, but it's not exactly the same. That's because this music was especially designed to relax you, or to give you extra energy. Sometimes you don't even realize the music is playing, but you react to the music anyway.

Quiet background music used to be called "elevator (电梯) music" because we often heard it in elevators. But lately we hear it in more and more places, and it has a new name "Muzak". About one-third of the people in America listen to "Muzak" every day. The music plays for 15 minutes at a time, with short pauses in between. It is always more lively between ten and eleven in the morning, and between three and four in the afternoon, when people are more tired. 2..

If you listen to Muzak carefully, you will probably recognize the names of many of the songs. Some musicians or songwriters don't want their songs to be used as Muzak, but others are happy when their songs are chosen. Why? 3..

Music is often played in public places because it is designed to make people feel less lonely when they are in an airport or a hotel. It has been proven that Muzak doeswhat it is designed to do. Tired office workers suddenly have more energy when they hear the pleasant sound of Muzak in the background. 4.. Supermarket shoppers buy 38 percent more groceries.

5.. They say it's boring to hear the same songs all the time. But other people enjoy hearing Muzak in public places. They say it helps them relax and feel calm. One way or another, Muzak affects everyone. Some farmers even say their cows give more milk when they hear Muzak!

A.Some people don't like Muzak.

B.The music gives them extra energy.

C.Music is playing in the background.

D.Factory workers produce 13 percent more.

E.Muzak tends to help people understand music better.

F.They get as much as $4 million a year if their songs are used.

G.Muzak is played in most of the big supermarkets in the world.

    A new study shows that rising levels of planet-warming gases may reduce important nutrients（营养物质）in food crops

Researchers studied the effects of carbon dioxide on rice， In the experiment， scientists grew 18 kinds of rice in fields in China and Japan．They set carbon dioxide levels to what scientists are predicting for our planet by the end of the century．Rice grown under high carbon dioxide conditions had，on average，13 t0 30 percent lower levels of four B vitamins and 10 percent less protein（蛋白质）The crops also had 8 percent less iron and 5 percent less zinc than rice grown under normal conditions However， vitamin E leveLs increased by about 13 percent on average．

The researchers said the effects of planet-warming gases would be most sevcre for the poorest citizens in some of the least developed countries．These people generally eat the most rice and have the least complex diets．That includes abour 600 million people in Indonesia， Cambodia，Myanmar，Bangladesh，Laos and other nations，mainly in Southeast Asia．

Other studies have shown that higher temperatures from climate change and weather extremes will reduce food production．But scientists are finding that rising levcls of carbon dioxide and other planet-warming gases threaten food quality．

Earlier studies showed that wheat，rice，field peas and soybeans grown under high carbon dioxide conditions all had Iower levels of protein and mincrais．Scientists predicted that almost 150 million people might be at risk of having too little protein or zinc in their diet by 2050．

The new study suggests a way to lower the nutritional harm of climate change．That is to grow different forms of rice that can adapt to higher carbon dioxide levels．

1.Growing rice under high carbon dioxide conditions may____．

A.increase iron in the rice

B.make it less nutritious

C.cause losses of Vitamin E

D.make it more delicious

2.How can people reduce the nutritional harm of climate change？

A.By importing rice from China and Japan．

B.By taking other kinds of food instead of rice．

C.By avoiding eating rice from Southeast Asia．

D.By growing rice suitable for the environment．

3.What’s the author’s purpose of writing the text？

A.To infom readers what nurrients food crops contain．

B.To call on people to care for the planet they live on．

C.To share the results of some studies on people’s diets．

D.To tell readers where food crops are mainly produced．

4.In which part of a magazine can you read the text？

A.Advertisements． B.Arts and culture．

C.Science report． D.Business news．

    Whether in the home or the workplace, social robots are going to become a lot more common in the next few years. Social robots are about to bring technology to the everyday world in a more humanized way, said Cynthia Breazeal, chief scientist at the robot company Jibo.

While household robots today do the normal housework, social robots will be much more like companions than mere tools. For example, these robots will be able to distinguish when someone is happy or sad. This allows them to respond more appropriately to the user.

The Jibo robot, arranged to ship later this year, is designed to be a personalized assistant. You can talk to the robot, ask it questions, and make requests for it to perform different tasks. The robot doesn’ t just deliver general answers to questions; it responds based on what it learns about each individual in the household. It can do things such as reminding an elderly family member to take medicine or taking family photos.

Social robots are not just finding their way into the home. They have potential applications in everything from education to health care and are already finding their way into some of these spaces.

Fellow Robots is one company bringing social robots to the market. The company’ s “ Oshbot” robot is built to assist customers in a store, which can help the customers find items and help guide them to the product’ s location in the store. It can also speak different languages and make recommendations for different items based on what the customer is shopping for.

The more interaction the robot has with humans, the more it learns. But Oshbot, like other social robots, is not intended to replace workers, but to work alongside other employees. “ We have technologies to train social robots to do things not for us, but with us,” said Breazeal.

1.How are social robots different from household robots?

A.They can control their emotions.

B.They are more like humans.

C.They do the normal housework.

D.They respond to users more slowly.

2.What can a Jibo robot do according to Paragraph 3?

A.Communicate with you and perform operations.

B.Answer your questions and make requests.

C.Take your family pictures and deliver milk.

D.Obey your orders and remind you to take pills.

3.We can learn from the last paragraph that social robots will ______.

A.train employees

B.be our workmates

C.improve technologies

D.take the place of workers

4.What does the passage mainly present?

A.A new design idea of household robots.

B.Marketing strategies for social robots.

C.Information on household robots.

D.An introduction to social robots.

    Papa, as a son of a dirt-poor farmer, left school early and went to work in a factory, for education was for the rich then. So, the world became his school. With great interest, he read everything he could lay his hands on, listened to the town elders and learned about the world beyond his tiny hometown. "There's so much to learn," he'd say. "Though we're born stupid, only the stupid remain that way.” He was determined that none of his children would be denied an education.

Thus, Papa insisted that we learn at least one new thing each day. Though, as children, we thought this was crazy, it would never have occurred to us to deny Papa a request. And dinner time seemed perfect for sharing what we had learned. We would talk about the news of the day; no matter how insignificant, it was never taken lightly. Papa would listen carefully and was ready with some comment, always to the point. Then came the moment—the time to share the day's new learning. Papa, at the head of the table, would push back his chair and pour a glass of red wine, ready to listen. "Felice," he'd say, "tell me what you learned today.” "I learned that the population of Nepal is ....”  Silence.

Papa was thinking about what was said, as if the salvation of the world would depend upon it. “The population of Nepal. Hmm. Well . . . . ” he’d say. “Get the map; let's see where Nepal is.” And the whole family went on a search for Nepal.

This same experience was repeated until each family member had a turn. Dinner ended only after we had a clear understanding of at least half a dozen such facts.

As children, we thought very little about these educational wonders. Our family, however, was growing together, sharing experiences and participating in one another's education. And by looking at us, listening to us, respecting our input, affirming our value, giving us a sense of dignity, Papa was unquestionably our most influential teacher.

Later during my training as a future teacher, I studied with some of the most famous educators. They were imparting what Papa had known all along—the value of continual learning. His technique has served me well all my life. Not a single day has been wasted, though I can never tell when knowing the population of Nepal might prove useful.

I will never forget the moment when we returned to school. Because the outbreak of COVID-19, we had to stay home and study from home in depression. I was touching when I stepped into the school, which everything was thoughtfully-arranged. The staff must have worked hard to keep it tidy and safe but we could study in a comfortable environment. There were sign telling us to wash hands frequently and wearing masks. Ms. Chen, our headteacher, greeted us warm in the classroom. A mask was covered most of her face, but her eyes were shining.

    Forgiveness comes from a positive attitude and a friendly nature. The process of it can be a releasing experience. In truth, forgiveness can only occur when we have been given the gift of the ability to make choices. 1.

The choice of offering forgiveness develops along three steps.

At step one you are filled with self-justified anger. At some point in your life you have been hurt and you are mad at the person who you feel has wronged you. You blame the person committing the wrong. 2. You have forgotten that you have a choice as to how you will react.

The second step toward forgiveness emerges (出现) when after feeling angry with someone for a while you realize that the anger does not make you feel good. 3. So you take steps to forgive. You may begin to see the problem from the other person’s point of view or you may simply decide to let the problem go. 4.

The third step of forgiveness comes after you have seen the beneficial results of forgiveness and you don’t want to waste your precious life in discomfort. In this step the choice is to work to either repair the relationship or let go of seeing the situation as a problem. 5. At this step you are aware that the length of time you experience the situation as a sorrow is primarily up to you.

A.If you want to forgive someone,no one can stop us.

B.We have the choice to forgive or not to forgive and no one can force us to do either.

C.In either case you decide to forgive because you have had some practice with it and seen the benefit in your life.

D.It is their action and not your choice of response that you feel causes your anger.

E.In either case you are no longer angry or you have forgiven the person.

F.This could emerge in a situation where you are cut off by another car on the road.

G.It may hurt your emotional balance or your physical health.

    “This has gone as well as I could have dreamed, and I can fly in the near future!” Yes, Alyssa Carson, a now-18-year-old astronaut from Baton Rouge, Louisiana is capable. For her, riding the most aggressive roller coaster in the park is not a big deal. If all goes according to her plans, NASA will send her to Mars in 2033, making her the first human to step foot on the planet. She will spend two to three years living there, growing food, performing science experiments and searching for signs of life. “The Martian is actually very accurate,” she said. “A lot of things that happened in the movie are similar to what is going to happen.” She has devoted her entire life to preparing for her journey.

Her love for space started when she watched a cartoon called The Backyardigans at the age of 3. Five animal pals on imaginary adventures in their backyard, including one part-a mission to Mars. “I thought ‘This red planet is so cool!’” she said. “I started watching videos of rovers’ landing on Mars. I had a large map of Mars in my room which I would look at every day. I started getting telescopes so I could look at space.

At 7, her father took her to space camp in Huntsville, Alabama. “That was the weekend of my life.” she said. I got to learn everything I had been wanting to know and I got to see a life-size rocket.” She cherished the rocket so much that she returned 18 times. At 12, she became the first person in history to attend all three NASA space camps in Huntsville, Alabama; Quebec, Canada and Izmir, Turkey.

At first she mastered the basics of space and how humans have explored it throughout time. As she got older she simulated (模拟) missions, trying to reach a destination in gravity-free, weightless zones.

When she was 9, she met NASA astronaut Sandra Magnus. The experienced explorer told her she was her age when she decided to go to space. At that moment Alyssa knew her love of space was not a hobby. “I did the same thing as other kids, like switching my mind about careers, wanting to be a teacher or the president one day,” she said. “But the way I always thought about it was I would become an astronaut, go to Mars, come back, and then be a teacher or the president.”

1.Which of the following about Alyssa Carson is right?

A.She has created model missions to Mars.

B.She is the youngest one who has completed astronaut training.

C.She is likely to be the first human to perform different tasks on Mars.

D.She has visited the space camp in Huntsville,Alabama for nearly 30 times.

2.What’s supposed to be stressed by referring to NASA astronaut Sandra Magnus?

A.The power of space dreams.

B.The popularity of space travel.

C.The importance of career choices

D.The excitement of her space experiences.

3.What can’t be inferred from the article?

A.The Backyardigans is a cartoon for kids.

B.Alyssa will have many tasks to complete if she lands on Mars successfully.

C.Alyssa was forced to learn the basics of space science by her father.

D.Alyssa enjoys riding roller coasters like many other young people.

4.What does the author intend to do in writing the passage?

A.To introduce American space industry.

B.To promote the values of American teens.

C.To encourage tours to Mars.

D.To present a rising American space star.

    Modern agriculture and its beauty to feed billions of people may be one of humanity’s greatest achievements. However, it comes with hidden costs. For example, have you ever considered how much water is needed to provide you with a steak or a salad? It may surprise you.

In a recent study published in the journal Nutrients, scientists from the Commonwealth Scientific and Industrial Research Organization (CSIRO), Australia’s national science organization, took a close look at the diets of 9,341 adult Australians-specifically, their “water-scarcity footprints (水消耗足迹)”.

It turns out that a sweet tooth not only adds to our waistlines but also stresses our water resources.

The water-scarcity footprint is a widely recognized measurement of water consumption. First, it counts the liters of water you used. Then, it looks at the place where the water was used. Using a liter of water in the desert is not the same as using a liter of water in a tropical rainforest. The more scarce water is in your area, the larger your water-scarcity footprint.

The scientists found that the average Australian’s diet had a water-scarcity footprint of 362 liters per day. Snacks and beverages-cookies, cakes, sodas and alcohol-accounted for 25 percent of the water-scarcity footprint. The research also included a glass of wine (41 liters), a single serving of potato chips (23 liters), and a small bar of milk chocolate (21 liters).

Not surprisingly, cutting out snacks would be the top priority if you wanted to lower your own water-scarcity.

Earth’s surface is 70 percent water, but only 2.5 percent of that can be used for drinking or farming. While humanity faces an uphill battle to feed its growing population, climate change is causing droughts and extreme weather in agricultural centers like California and eastern Australia.

Cities aren’t safe, either. In 2018, Cape Town, South Africa, nearly ran out of water due to drought. Its freshwater reservoir (水库) stayed at just about 13.5 percent of full capacity.

By 2030, a world of about 8.6 billion people will need 35 percent more water, 40 percent more energy, and 50 percent more food, according to the United States National Intelligence Council.

So, we need to watch what we eat, not just for our personal health but for the health of our societies.

1.What did the recent study from CSIRO find?

A.There are many hidden places like lacking water.

B.The foods we consume could cause our water-scarcity footprints to be bigger.

C.Climate change is the leading reason for larger water-scarcity footprints.

D.Eating sweets leads to a smaller water-scarcity footprint.

2.What do we know about water-scarcity footprints?

A.They show how much a person affects their local water supply.

    As we know it, it’s not unusual to find such private message on Facebook: “Hey, girl. Wanted to invite you to join my next challenge group-we’ll be focusing on fitting in 30 minutes of exercise and balanced nutrition.”

It was all becoming too much. Facebook was running my life, not me.

But what killed Facebook for me was when I posted a photo, and five minutes later my son asked me how much “likes” it had got. His question was a wake-up call.

“Likes” are signs of acceptance and approval. I had forgotten that acceptance and approval need to come from within and had unknowingly set him a bad example.

Before Facebook, surfing the Internet was an occasional distraction and I spent a lot more time reading books and magazines. I checked in with friends through texts, emails and phone calls.

To recreate the simplicity of those days and set a healthier example for my son, I deactivated my Facebook account.

I’d been in the habit of checking Facebook many times a day, so I had to come up with some new habits. I carried a novel and a crossword puzzle book around with me. I rediscovered knitting. I started taking yoga classes.

I started to remember a few things. My body is fine just the way it is. I have friends who will help me out when I’m in trouble, and I’ll help them out. I do my best to be a good mother, and our son is happy and healthy. We are lucky to be able to afford two vacations a year.

I stopped looking at the world through my cellphone. I felt completely present in the moment.

The break left me feeling better about myself, my family, my home and my life.

After a few weeks, I returned to Facebook. Now I look at the photos of my friends’ kids growing up and treasure how social media allows me to keep in touch with family far and wide. I look in on a daily basis, but no longer with the desire constantly to post updates.

A Room of One’s Own

This essay by English writer Virginia Woolf is based on several lectures given to two women’s colleges at Cambridge University in 1928. In the essay, Woolf describes that it’s circumstance not talent alone, that allows men to be more successful at writing. Women, in other words, spend so much time cooking, cleaning, and tending to their children that they have no time left for art. To write well, therefore, a woman must have a “room of her own”. While on its surface, this essay appears to be only about writing, it is actually about wealth and class, freedom and confinement, and the power struggle between sexes.

The Art of War

Written by ancient Chinese warrior Sun Tzu, The Art of War is widely considered to be one of the best books about military strategies in human history. Consisting of 13 chapters, each dealing with a separate aspect about how to fight a war, the book has been translated into every major language and has thousands of editions. For centuries, it has been used to train world leaders for its detailed study of military strategies and effective leadership.

Letter to My Daughter

This book of essays by Maya Angelou, a respectable African-American poet, is written for “the daughter she never had” — the millions of women, both young and old, that she considers to be her “family”. From the viewpoint of a caring, older relative, this book contains lessons selected from her own life experiences, including the birth of her only child, a son, as well as the development and loss of friendship.

A Brief History of Time

If you’re short of time, then why not read about, well, the creation of time? This book, first published in 1998 from brilliant scientist and mathematician Stephen Hawking, explores mind-bending questions about the creation of the universe, including if and when it will end, and if so, how. Despite its heavy subject matter, Hawking addresses these questions in a way that’s easy to understand, even for those who know little about physics.

    Many adults see rainy days as perfect for relaxing and curling up with a good book or a favorite movie. 1. They want to run, play, and release their pent-up energy. The situation isn’t hopeless, though. There are many rainy day activities that are perfect for children of all ages.

As soon as kids begin to feel frustrated from being trapped in the house, they will become destructive, and the kitchen table and chairs will become jungle gyms. In this case, help them to release their energy in a productive manner. Try turning the music loud and dancing.2.

Rainy days often lead to a desire for sweet treats, so make baking one of kids’ favorite rainy day activities. Grab the kids and make some cookies, cakes or pies. Allow the kids to do most of the work, except for handling sharp objects or touching the stove or oven.3. They will also be content with a stomach full of warm cookies and milk.

4.These give the kids a chance to develop their imagination and improve their fine motor skills. Set the kids up in an area of the house that is easily cleaned up. Allow them to explore their creativity.

Playing dress-up is one of kids’ favorite rainy day activities. Pull out some clothes that aren’t worn often and have the kids dress up.5. If a video camera is handy, record it and let the kids watch it with a bag of popcorn.

A.Try putting together a game of mud football.

B.Rainy day activities often include art projects.

C.Make it even more exciting by putting on plays.

D.On the other hand,many kids see rainy days as boring

E.Rain won’t hurt the kids,and can be a nice change of pace.

F.After their energy is released,the kids can do quiet rainy day activities.

G.The kids will be very proud of themselves for completing such an activity.

    Many studies link music study to academic achievements. But what is it about serious music training that seems to associate with great success in other fields?

I put the question to top-flight professionals in industries from tech to finance to media, all of whom had serious (if often little-known) past lives as musicians, Alan Greenspan, former chairman of the Federal Reserve, was a professional saxophone player. The billionaire Bruce Kovner is a pianist who took classes at Juilliard. Almost all made a connection between their music training and their professional achievements. Mr. Greenspan says, ''I can tell you as a statistician, the probability that that is mere chance is extremely small. That's all that you can judge about the facts. The important question is: why does that connection exist? ''

Paul Allen, the billionaire co-founder of Microsoft, offers an answer. He says music ''builds up your confidence in the ability to create''. The music had the emotional similarity to his day job, with each giving a different type of motivation. The NBC chief White House correspondent Chuck Todd, who attended college on music scholarships, says there is a connection between years of practice and competition and what he calls the ''drive for perfection''. He adds, ''The group playing trains you, quite literally, to play well with others, to know when to solo (独奏) and when to follow. ''

For many of the high achievers I spoke with, music functions as a ''hidden language'', as the former World Bank president James Wolfensohn calls it, one that improves the ability to connect diverse or even contradictory ideas. According to him, music may not make you a genius, or a better person. But it helps train you to think differently, to process different points of view-and most importantly, to take pleasure in listening.

1.How does Alan Greenspan find the connection between music training and professional achievements?

A.It's relatively weak. B.It's not common fact.

C.It's not a coincidence. D.It's widely acknowledged.

2.What quality does music equip Chuck Todd with?

A.Teamwork. B.Confidence.

C.Creativity. D.Tolerance.

3.How does the author mainly develop the text？

A.By comparing different facts. B.By debating and concluding.

C.By self-questioning and answering. D.By offering concrete examples.

4.What can be inferred from the text?

A.Music contributes to success. B.Music is the universal language.

C.Music can change your career. D.Music is linked to academic success.

    Want to get your package delivered via robots? Now there’s an app for that. If you live in Washington D.C., or Redwood, you may have glimpsed a small, boxy robot rolling along a local sidewalk, minding its own business, but attracting the attention of many curious onlookers.

The autonomous machines were part of a pilot program last year by Starship Technologies focusing on delivering meals from local restaurants in dozens of cities around the world. This week, the company unveiled plans to broaden its delivery service beyond food to include package, a move that led it to declare itself “the world’s first robot package delivery service”. The next time you order food, this cute robot might roll up to deliver it. The package delivery service is not available to everyone yet.

The wheeled robots have a top speed of 4mph and can detect obstacles from 30 feet away. “The robot can operate through anything,” Nick Handrick, head of operations for Starship’s D.C. office, sad, “If you had something in the way-a stick –it’s able to climb sticks.”

To sign up for the service, which costs a little more than $10 per month, customers need to download the company’s app. Customers then create a “Starship Delivery Address”, a unique address inside a Starship facility, where they can have package sent from places such as Amazon.com. Once a package is delivered to the Starship address, customers receive a text notification that allows them to schedule a home delivery via robot. The robots are opened by customers via a mobile phone code.

Barriers exist for robotic ground delivery, with many states requiring that humans be in control of delivery robots. Those regulations haven’t stopped Starship Technologies from accumulating experience on streets around the globe ahead of the company’s latest launch. The company says its robots have covered more than 125,000 miles in more than 100 cities in 20 countries.

1.What can we know about the robotic delivery?

A.It is part of a trial project by Starship Technologies.

B.The robotic delivery is available to everyone at present.

C.You can use the service free of charge via smart phones.

D.The robots are opened by customers with a text notification.

2.What does the underlined word“unveiled”in paragraph 2 probably mean?

A.Revised. B.Released. C.Restored. D.Reset.

3.What is the last paragraph mainly about?

A.The good news of the service.

B.How the robotic delivery works.

C.The disadvantages of the robotic delivery.

D.Robotic delivery develops despite challenges.

4.What can be the best title for the text?

A.New Robot Was Invented B.Wheelless Robots Are on the Way

C.How Robots Deliver Packages D.Packages Will Be Delivered by Robots

    Recently Stiles aged 17 took her 3-year-old brother, James, to her high school. A family emergency prevented her parents from being able to pick up James. So they asked Stiles to step in.

“This was a one-time event; we have never had her get him from school other than this day. But it was an emergency,” her mother said. “I figured she had gone to get him and taken him home. Later that day I saw the picture online and realized that she had taken him back to school.”

Recently I took a part in a geography research activity, whose theme was environmental pollution and protection. We took variety pictures showing the present pollution conditions of our city. To our surprise, there are still a great number people doing silly things to our surrounding. Some people often throw rubbish whichever they like. Some cars gave off harmful gases and waste water is pouring into rivers by some factories. Worse still, people sometimes have to make his way through dusty winds as a result of the pollution. Through our research, we have come to realize what everybody must pay more attention to protect our environment and that some measures should be taken to protect it.

    Luis Escobar, a coach at St. Joseph High in Santa Maria, was just looking for a fun idea to change the practice for his summer program. _______, he took 14 runners from his school to the local animal shelter, and paired them with 14 dogs.

    As your teacher passes out the math test, your palms turn sweaty. You notice that your heart has begun to race. Glancing down at the page, you suddenly forget those operations on which you had drilled only a few days earlier. Do you perform all additions first in a complex calculation? 1. Suddenly, you start to doubt a lot of things that you know.

If that sounds familiar, you might suffer from math anxiety. Or maybe not Even researchers who study this condition note that it can be surprisingly hard to define (下定义) math anxiety. 2. After all, it's not an officially recognized mental disorder in the way that depression is.

3. It asks things like “how anxious would you feel about being given a set of division problems to solve on paper”. Those who score high on these surveys about stress over making calculations related to numbers will be labeled math anxious.

In general, people who panic over their math skills tend to do worse in math classes than people who don't mind numbers. 4. “Just because you're math anxious, that doesn't always mean you're bad at math,” notes Rose Vukovic, an educational psychologist at the University of Minnesota in Minneapolis.

Math anxiety affects people of all ages. It can lead to poor performance in math classes. 5. Throughout life, this type of stress can stand in the way of mastering skills or projects in a host of areas that rely on calculations. But the good news is that the problem is manageable. Researchers are finding ways people can cope with this stress.

A.But that's not always true.

B.It has an unimaginable impact.

C.And its impacts don't end at graduation.

D.Oh, you know it—well you' re pretty sure, right?

E.To diagnose math anxiety, researchers conduct a questionnaire.

F.It's also hard to identify precisely how many people suffer from it.

G.Math anxiety has also been linked to negative emotions from the past.

    Imagine that you found a wallet in the street containing a stranger 's contact details but no cash. Would you go out of your way to return it to its owner? Now imagine that the same wallet contained a few banknotes. Would that change your response? Alain Cohn of the University of Michigan and his colleagues have taken such behavioral economics around the world.

In different countries Dr. Cohn's research assistants entered public buildings like banks, museums and police stations. They handed in a fake wallet to an employee in the reception area, saying they had found it on the street outside, before making a hurried exit. Each wallet was a see-through plastic card case containing three identical business cards with a unique email address and a fake native's name, a shopping list and a key. Most importantly, some wallets also included $13.45, while some had no cash. Then, the team simply waited to see who would email the “owner” about returning the wallet.

In 38 of the 40 countries, the wallets with money in them were returned more often than those without: 51% compared with 40% for the cashless. While rates of honesty varied greatly between different countries, the difference within individual countries between the two return rates was quite stable around 11 percentage points. In addition, wallets containing a larger sum of money ($94.15) were even more likely (by about another ten percentage points) to be returned than those with less, although the “big money” experiment was done in only three countries.

With greater temptation (诱惑), then, comes greater honesty - at least when it comes to lost wallets and small cash. Interestingly, though, when Dr. Cohn and his team surveyed a sample of 299 volunteers, most of them predicted that the more money there was in a wallet, the more likely it was that it would be kept.

A certain doubt about the motivation of others is probably good for survival, so the response of the general population may be understandable. But is the warm inner satisfaction coming from “doing the right thing” also a powerful reason? As this study shows, such thought is real and universal

1.What does Dr. Cohn's research team try to find out?

A.How long it usually takes before a lost wallet is returned.

B.How people of different occupations react to lost w alts.

C.How people behave differently at public and private places.

D.How people respond to lost wallets of varying amounts of cash.

2.What is the second paragraph mainly about?

A.Work division in the team. B.Detailed arrangements.

C.Contents inside the wallets. D.Preparations made in advance.

3.What does Dr. Cohn's research find about rates of honesty?

A.They drop with bigger money. B.They vary from country to country.

C.They are quite the same globally. D.They are stable, unrelated to money.

4.From which is the text probably taken?

A.A research paper. B.A travel brochure.

C.A psychology magazine. D.An economy newspaper.
