I think there are several reasons that suggest developing robots is a waste of money.

In San Diego recently $325,000 was spent on inventing a robotic squirrel to do some scientific experiments. The research proved that squirrels are able to scare away snakes by wagging (摇动) their tails. Do you need a robotic squirrel to work this out?

What about AIBO, a robotic pet, developed in Japan? In Japanese aibou means “buddy”. These pets have been developed at huge cost mainly to provide entertainment. They've been used in movies and music videos. Universities have used them for educational purposes. However, in 2006 the company stopped producing these robotic pets in order to save money. Was it worth a lot of money?

Then there’s NAO, a robot which has been developed by a French company. Its main purpose is to make life easier for humans. It speaks 19 languages and has its own personality. It can tell children a story, help in the classroom or the home, or act as a companion to those people who need someone to be with. A fully developed one costs $16,000. Is that value for money? Who can afford it anyway?

There may be good reasons why it is worth developing robots, but so far I haven’t thought of any.

1.What does the underlined word “companion” in Paragraph 4 mean in Chinese?

A.公司 B.机构 C.对手 D.伙伴

2.What is the true fact about the robots mentioned?

A.The robotic squirrel is needed by every scientist to do some research.

B.AIBO wasn’t made any more because it only provided entertainment.

C.A fully developed NAO may tell kids stories in different languages.

D.All the three types of robots used to be produced at a very low cost.

3.What does the writer think of developing robots?

A.It can help bring people a lot of fun. B.It has advantages in many ways.

C.It may be useful but costs too much. D.It is worth a great deal of money.

Not all teenagers do well at school but why is that? There are plenty of theories—poverty, IQ., family background. 1.

A recent study in the U．S. found that over half of all high school students do not study hard. 2. A report from the U．K. shows that nearly a third of students do not complete their education because they don’t think their schooling is collected to the kind of work they will do in the future.

How can teenage students study harder? 3. His research suggested that a new model of schooling was needed—a model that connects what students are learning to their own plans for their future.

4. About 80 percent of the courses in the Studio School are done not through sitting in classrooms but through real­life.

Studio schools are smaller than traditional schools. Each student has a “personal coach” who helps him or her make a plan to achieve their learning goals. By having more practical goals, students become more determined to do well at school.

Mulgan says Studio Schools are based on a simple idea. 5. This simple idea is spreading. From just one school in 2010, Studio Schools had grown to more than 40 by 2014.

A.Mulgan helped create the Studio School.

B.Researchers also discovered some other reasons.

C.Researchers think some students are not active in schools.

D.They put teamwork and practical projects at the heart of learning.

E.Geoff Mulgan believes the solution lies in making learning more practical.

A new study suggests that the more teenagers watch television, the more likely they are to develop depression (抑郁症) as young adults.

The researchers used a national long-term survey of healthy young teenagers of about 13—16 to find out the relationship between media(媒体) use and depression. They based their findings on more than 4000 young teenagers who were not depressed when the survey began in 1995.

As part of the survey, the young people were asked how many hours of television or videos they watched daily. They were also asked how often they played computer games and listened to the radio. Here was the result. The young people spent five and a half hours a day using media and more than 2 hours of that was spent watching TV.

Seven years later, in 2001, more than 7% of the young people had signs of depression. The average age at that time was 21. Brian Primack at the University of Pittsburgh medical school was the lead author of the new study. He says every extra hour of television meant an 8% increase in the chances of developing signs of depression.

The researchers say they did not find any such relationship with the use of other media such as movies, video games or radio. But the study did find that young men were more likely than young women to develop depression given the same amount of media use.

Doctor Primack says the study did not find out if watching TV causes depression directly. But one possibility, he says, is that it may take time away from activities that could help prevent depression, like sports and social activities. It might also prevent a person from sleeping well, he says, and that could have an influence.

The study was just published in the Archives of General Psychiatry.

In December, the journal Social Indicators Research published a study of activities that help lead to happy lives. Researchers from the University of Maryland found that people who describe themselves as happy spend less time watching television than unhappy people. The study found that happy people are more likely to be socially active, to read, attend social services and to vote.

Experts in nutrition suggest that we should eat at least five different kinds of vegetables and fruit a day. They are very necessary for our health and help our bodies work well. They can help reduce the risk of getting ill. There are a lot of vegetables and fruit to choose from and they taste delicious. 1.

It's easy to buy our food from the local supermarket, so why do we go to the trouble of growing our own? Here are several good reasons：

2. You can pick and eat it at once. When you have tried it, you will agree that vegetables and fruit that are eaten straight from the garden taste better than anything you can buy in a supermarket.

You may want to cut down on your “food miles”—the distance that a product has travelled before it reaches your kitchen. Many food packages are flown halfway across the earth. 3.

Homegrown food is likely to be healthier. Food producers often use fertilizers and pesticides which can end up in your food. If you grow your own, things are different. 4. You might also choose to grow some traditional vegetables and fruit. These often have more important things that keep you healthy.

5. And you can grow your own even if you only have a small backyard. Some food can grow well in pots, including tomatoes, potatoes and carrots. You can recycle plastic bottles and cups to grow something. Just make sure there are holes for drainage and a small plate under them to catch drops of water.

A.Best of all, you can grow your own!

B.That's not so good for you, or for the planet.

C.Food that you grow yourself is always fresh.

D.If you have a large garden, growing your own is easy.

E.You can control what goes on and into the food you eat.

New research shows the number of suicide（自杀）is increasing among young people. Between 2007 and 2015, the number of U. S. teenagers who visited hospitals because of suicidal thoughts or ideas doubled. In 2007, the number of visits was 580,000; by 2015, that number had increased to 1.12 million, reports CNN.

The fact that so many young people fight with depression （沮丧） and suicidal thoughts every day is shocking. But new research may allow us to look into the differences between the development of depression in boys and girls.

Researchers found that there are big differences between the development of depression for boys and girls. Girls seemed to develop depression at a faster speed and hit the highest levels of depression at an earlier age. For boys, the most rapid increase of depression happened at age 16. 4, while girls' biggest increase came at 13. 5 years.

There's no exact answer for these differences. But expert Arash Emamzadeh says that a general increase in depression during teenage time is possibly "because teenagers face many changes during this period such as puberty(青春期) , school transition(过渡) and forming friendships. "

As for girls experiencing depression at an earlier age, Emamzadeh writes, "One possible explanation for this difference is the earlier puberty in girls compared with boys. "

Finding a solution is not easy. However, if schools, parents and teenagers make efforts at the same time, things will certainly be better. Students in schools need to be helped to deal with problems both in their daily lives and study. Less stress is supposed to be put on teenagers' shoulders by parents. Proper communication between teenagers and parents is necessary. Teenagers should keep optimistic and look on the bright side of life.

1.How many teenagers with suicidal thoughts are there in the U. S. by 2015?

A.1.120,000. B.1, 700,000. C.580,000. D.540,000.

Every 14 days, another language dies. There are many reasons for this. Some people think more common languages have more economic(经济的)power. Because of this, young people choose to learn a common language as they think it is more useful. Another reason is that some languages aren't written down. Guujaaw is a leader of the Haida Nation, whose people have lived on the Queen Charlotte Islands, Canada, for more than 10, 000 years. Their language is endangered. Traditionally, it wasn’t written down, and, as a result, some people are worried that it will die one day. Guujaaw replies to this, "We talk to each other, listen, visit, and believe in the spoken word. Expressing yourself without writing is natural." However, if Guujaaw's language and others like it are going to stay alive, writing may have to become part of their lives.

When a language dies, a lot of knowledge dies with it. To begin with, language is a huge part of the culture of the people who speak it. Language allows speakers to say certain things: words that describe a cultural idea may not translate exactly into another language. Furthermore, many endangered languages have rich spoken cultures, Stories, songs and histories are passed on from older people to younger generations(一代), Elizabeth Lindsey, an expert in languages, emphasizes(强调) this. “When an elder dies, a library is burned,” she says.

Also, language death affects our knowledge about nature. Local people often have a deep understanding of plants, animals, and the relationship between them. David Harrison, a researcher on endangered languages, reflects, “80% of plant and animal species(物种)have been undiscovered by science. But that doesn’t mean they're unknown to humans.”

Many languages are endangered. However, it s not too late. Children often grow up speaking two languages. "No one ..becomes richer by giving up… one language to learn another,” Harrison said. If children feel both languages are important, they will use both. So, it is necessary that children realize how useful their local language is.

1.How many reasons are mentioned for endangered languages in Paragraph 1?

A. 2　　 B. 3.　　 C. 4　　 D. 5.

2.In Paragraph 2, the writer mainly tells us_____.

A. how cultures are passed on　　 B. how cultures are discovered

C. why languages are written down　　 D. why languages are important to cultures

3.The underlined word "affects" in the passage means “_______”.

A. waits for　　 B. depends on

C. is different from　　 D. has an influence on

4.Which of the following is the writer's opinion?

A. People need to use common languages more often.

B. The spoken word is more important than the written word.

C. Children are the hope to stop the local language from dying.

D. Many animals and plants are in danger because of dying languages.

These days, teenagers are heavily influenced by the media. Many of them have watched thousands of hours of TV. That's more time than they spend with teachers at school. And we haven't yet considered the hours they spend using the Internet and reading newspapers.

However, several studies have shown a serious problem: today's teenagers lack media literacy (媒体素养). In other words, they have difficultly critically thinking about the information they see. One study that was done on middle school students showed that more than 80 percent of them couldn't tell the difference between real stories and ads that　　　　　　　　 looked like news.

Standford professor Kevin John teaches a class called Media Effects. He tries to help his students learn media literacy. The professor gave an example that shows why media literacy is important. In the example, two news stations report a snowstorm. One focuses on (关注) the terrible road conditions. The other focuses on kids playing in the snow. "With a news story. news stations tell you what they feel are the important details (细节). These details mostly depend on the opinions of the news director." said John. "A person who has media literacy would realize that each story is about one side at this time. There is more going on."

Some experts think shoe is the best place to teach media literacy. Other believe everyone—form parents to reporters—should help teenagers learn the skills.

As for the best time to start learning media literacy, many experts suggest the age of 12. But some basic ideas can be taught even earlier. "It's never too early to start learning media literacy," John said.

1.From the first paragraph, we can learn that teenagers today spend more time ______.

A.using the Internet than watching TV

B.watching TV than studying at school

C.studying at school than reading newspapers

2.The underlined word "lack" in Paragraph 2 probably means ________.

A.缺乏 B.质疑 C.误解

3.The example shows that a person who has media literacy _______about a news story.

A.should have the same opinions as others

B.could think about is good and bad sides

C.must know about all the important details

4.Professor Kevin John would agree that _______.

A.everyone is supposed to help children learn different skills

B.children should be taught media literacy as early as possible

Have you ever had an experience where you meet someone new, learn their name and think to yourself, "Wow, they really look just like their name!" What does this mean, exactly? Scientists are suggesting that humans tend to associate people's names with their appearance, and can even guess someone's name based on how they look.

Researchers at the Hebrew University of Jerusalem in Israel collected thousands of photos of people faces. They labeled (贴标签)each photo with four names. Then, they asked volunteers to guess which of the four names was correct.

The volunteers were able to guess the right name 38 percent of the time. It seems that humans are able to recognize certain characteristics of faces that can give them clues (线索)about someone's name, Reader's Digest reported.

However, this only works when we're looking at names within our own culture. In addition, the volunteers were not as good at guessing the real names of people who use nicknames (昵称) more often than their real names. This shows that a person's appearance is affected by their name only if they use it often.

This kind of face- -name matching happens because of a process of self-fulfilling prophecy(自我实现预言), as we become what other people expect us to become," Ruth Mayo from the university told science news website EurekAlert.

Previous studies have shown that gender and race (种族)stereotypes (刻板印象)can affect a person's appearance. The researchers believe there are also similar stereotypes about names. For example, people tend to think that men named Bob should have rounder faces because the word itself looks round,people may think that women named rose are beautiful. They expect them to be delicate and feminine, just like the flower they are named for.

1.What does the passage mainly tells?

A.People can guess others' names based on their appearance.

B.A person's appearance can be affected by three factors.

C.There are several ways to guess a stranger's name.

D.It's not polite to ask strangers about their names.

2.Dr. Ruth Mayo thinks some people look like their names because of ________.

A.racial stereotypes B.their unique culture

C.a self-fulfilling prophecy D.their living environment

3.According to the passage, men named Bob are expected to ________.

A.wear glasses B.have big eyes C.look beautiful D.have round faces

4.What do we know from this research?

A.Nicknames have a bigger influence on people's appearance.

B.Gender and race have no influence on a person's appearance.

C.The volunteers guessed nearly four names correctly out often.

D.People are good at recognizing the different characteristics of faces.
