The winter holiday is usually a good time to sleep in． But Gao Yuqi， a 14﹣year﹣old boy from Anhui， got up at 7： 00 am to run at least 2 kilometers every day during the holiday． In fact，this exercise was part of this homework．

Gao was not alone． Many schools across the country required students to exercise during the winter holiday． Part of the reason is that physical education test scores are now worth more on the senior high school entrance examination （ 中考）． And the score is now worth up to 60 points．

Because of this， Gao's school now asks students to run when the weather is nice， and exercise indoors if it is bad． Students have to post（公布）exercise photos in their classes' QQ groups． At the Golden Apple Jincheng No． 1 Middle School in Chengdu， students have daily exercise plans． For example， they have to skip rope（跳绳） for two minutes and do three sets of sit﹣ups（仰卧起坐） each day． Their parents sign off（签名）on their plans when they finish exercising．

This has been a big challenge for many students， but has also helped to make exercise a bigger part of their lives． Many students like Gao used to hate running， but now they are able to run for over half an hour every day． They fell in love with exercise during the holiday．

"Mom， "said Trevor， as he watched his mother washing the old cans （罐）， "why are you washing these old cans？"

   "I'm getting them ready for being put into the recycling box，" said Mom．

   "Well， they are rubbish to us， because we don' t need them anymore． I wash the cans out so that they won't attired insects，" said Mom． "We don' t use some things， but it doesn't mean they have no value． These cans can be melted （熔化） down to make new cans or other things．"

   "I didn't think of that，" said Trevor． "Is that why you save all the cardboard（纸板） or newspapers too？"

   Mom nodded， "That is also why I save all those vegetable bits， I use them all in our garden．"

   "Our teacher told us about projects other classes had done for Earth Day， and she asked for suggestions for our class projects． I can't think of anything． Do you have any good ideas， Mom？" asked Trevor．

March 16 is International Sleep Day． Studies have shown that a good night's rest helps us stay healthy， both mentally（精神地） and physically（身体地）． Sleep is probably the best tool we have for memory and learning． A good night's sleep helps to learn better．

   But what about getting rest during the middle of the day？ Short periods of sleep after a mid﹣day meal， we call it napping（午睡）， may help our brains work better．

   Past studies have shown that napping can help babies and young children learn better． And napping can help brain performance in older adults． Taking a nap may also help this group of peoplefight off age﹣related memory loss． As we all know， the older we are， the more memory we will lose．

   The study found that people who took an hour﹣long nap did much better on mental tests than those who did not nap． The hour﹣long nappers also did better on the tests than those who napped for shorter and longer periods． In this study， it seems that the most effective（有效地） nap lasted for about an hour， but not much longer． Keep in mind， however， that these are the findings for those over the age of 65．

And there is a little difference between the old and young people． Doctor Michael Twery notes that an hour long nap may be too long for young， healthy adults． And 30 minutes is enough to remove the pressure to sleep and will help them feel more awake（清醒的）． If they nap longer， they will get trapped into（受困于） deep sleep， which can be hard to get out of．

If you have trouble falling asleep at night， limit（限制） your daytime nap to under 45 minutes． Also nap before 3 p．m． in the afternoon．

（1）When is the International Sleep Day？

A new study finds that plants communicate with one another to warn of danger.
We often consider plants as the furniture of the natural world. They don’t move; they don’t make sounds, they don’t seem to act on anything. But as is often the case, plants talk to each other all the time. And the language is chemical.
Over the years, scientists have reported that different types of plants, from trees to tomatoes, give out chemicals into the air to help neighboring plants. These chemical warnings can spread information about one plant’s disease or infestation(虫害), so other plants can protect themselves. But how plants receive and act on many of the information exactly is still mysterious.
In this week’s Science Magazine, researchers in Japan offered some explanations. They have found out one chemical message and traced it all the way from beginning to end.
The scientists looked at tomato plants infested by a common pest(害虫). To start out, they grew plants in two separate plastic spaces connected by a tube(管子). One plant was infested and placed upwind and the other was uninfested and placed downwind. The downwind plants were later exposed(暴露) to the pest. The results showed that plants near sick neighbors before were able to protect themselves better against the pest.
They found one chemical appeared more often in the exposed plants. The chemical is called HexVic. The scientists discovered where HexVic come from, and put it over healthy plants. Those plants were then able to produce HexVic. Researchers made sure that uninfested plants could fight off bugs and diseases. How do they know when to protect themselves? They are warned first by their friendly plant neighbors.
It is not a simple story, and it may be happening in more plant species than tomatoes. It may also be happening with more chemical signals that are still unknown to us. In a word, we know that plants not only communicate, but also look out for one another.
The underlined “traced” in the fourth paragraph probably means _________ here.

A．reported	B．followed
C．doubted	D．developed

For scientists, which are the right steps to watch tomato plants infested by a pest?
①  Place the infested plant upwind.
②  Place the uninfested plant downwind.
③  Expose the downwind plants to the pest.
④  Grow plants in two separate plastic spaces connected by a tube.

A．③①②④	B．①④③②
C．④①②③	D．④②①③

You can put the sentence “The researches also studied leaves from exposed plants and unexposed plants.” At the beginning of

A．Paragraph 3	B．Paragraph 4
C．Paragraph 5	D．Paragraph 6

Which of the following can be the best title of this passage?

A．Communicating Plants and Terrible Diseases

B．Talking Plants and Friendly Warnings

C．Protecting Plants and Clear Information

D．Growing Plants and Mysterious Chemicals

Today almost everyone knows computers and the Internet. If I ask you “What is the most important in your life?” maybe you will say “Computers and the Internet.”
The first computer was made in 1946. it was very big but it worked slowly. Today computers are getting smaller and smaller. But they work faster and faster. What can computers do? A writer has said, “People can’t live without computers today.”
The Internet came a little later than computers. It is about twenty-five years later than computers. But now it can be found almost everywhere. We can use it to read books, writer letters, do shopping, play computer games or make friends.
Many students like the Internet very much. They often go into the Internet as soon as they are free. They make friends on the Internet and maybe they have never seen these friends. They don’t know their real names, ages, and even sex. They are so interested in making the “unreal friends” that they can’t put their hearts into study. Many of them can’t catch up with others on many subjects because of that.
We can use computers and the Internet to learn more about the world. But at the same time, we should remember that not all the things can be done by computers and the Internet.
The Internet can not be used for______.

What do people do with their old, out-of-date but still useful computers? Most people don’t know what to do with them. Many old computers are put away in homes. Many more are simply thrown out with the rubbish.
Finally, some companies are thinking of ways to bring down the number of old computers. Sony has agreed to help recycle old Sony products（产品）. Dell, Hewlett-Packard and other companies now also take back some old computers.
In some countries, laws（法规）are being passed, too. Computer companies will have to pay for collecting and recycling their used products. And 70% of computer waste must be recycled. The idea behind the laws is that computer companies themselves should pay the cost. That will encourage them to make computers that are easier and cheaper to repair and upgrade（升级）.
Yet while many people are throwing away good computers, others cannot afford them at all. Hundreds of organizations（组织）are working to solve this problem. They collect and repair old computers. Some also teach others how to repair computers.
The computers then go to schools, charities（慈善团体）and people who need them. Giving a used computer to one of these organizations can turn one person’s rubbish into someone else’s useful things—and cut down on waste, too.
What do many people do with old computers?

A．They repair them.	B．They sell them.
C．They send them to others.	D．They stop using them.

D．Turn rubbish into useful things.

What is the main idea of this passage?

A．Repairing old computers.	B．Encouraging to make cheap computers
C．Recycling old computers.	D．Helping those who need computers.

Why do we need to throw less away? There are two reasons. One is that some resources （资源） are nonrenewable （不可再生的） That means there is only a certain amount of that resource in the world . One example of this is oil. When we use up all the oil in the world, there will be no more.
There is another reason for throwing less away. All of our trash has to be put somewhere. Often , it is put into garbage dumps （垃圾场）. Much of that trash will be there for hundreds of years. The dumps will be filled up with all this trash.
There are three ways to cut down on trash.
One way is to recycle. When you recycle something, it means it is made into another shape and used again. Old newspaper may become paper bags. A glass jar can be melted（熔化）and made into a bottle .
Another way to cut down on trash is to reuse things. You can wash and use again a bottle that can hold mustard （芥末酱）or something else .
The third way to cut down on trash is to reduce the amount of trash you make, stop buying thing that you don’t need in the first place. That reduce the amount of the earth’s resources that you use.

More than 50,000,000 people live in the rainforests of the world and most of them do not hurt the forest they live in. They eat the fruits that grow on the forest trees, but they do not cut them down. They kill some animals to eat, but they do not destroy them.
When we cut down the rainforests, we destroy these forest people, too. In 1900, there were 1,000,000 forest people in the Amazon forest. In 1980, there were only 200,000.
The Yanomami live along the rivers of the rainforest in the north of Brazil. They have lived in the rainforest for about 10,000 years and they use more than 2,000 different plants for food and for medicine. But in 1988, someone found gold in their forest, and suddenly 45,000 people came to the forest and began looking for gold. They cut down the forest to make roads. They made more than a hundred airports. The Yanomami people lost land and food. Many died because new diseases came to the forest with the strangers.
The Yanomami people tried to save their forest, because it was their home. But the people who wanted gold were stronger.
Many forest people try to save their forests. Chico Mendes was famous in Brazil because he wanted to keep the forest for his people. “I want the Amazon forest to help all of us-forest people Brazil, and all the Earth,” he said. A few months later, in December 1988, people who wanted to cut down the forest killed Chico Mendes.
In Borneo, people were cutting down the forest of the Penan people to sell the wood. The Penan people tried to save their rainforest. They made blockades across the roads into the forest. In 1987, they closed fifteen roads for eight months. No one cut down any trees during that time.
In Panama, the Kuna people saved their forest. They made a forest park which tourists pay to visit.
The Gavioes people of Brazil use the forest, but they protect it as well. They find and sell the Brazil nuts(坚果) which grow on the forest trees.
The number of the people living in the Amazon forest in 1980 was _______ of that in1900.

A．half

B．one-third

C．two-fifths

D．one-fifth

The people who _______ have destroyed the rainforest of the Yanomami.

D．made the roads and the airports

Those people built roads and airports in order to ________.

A．carry away the gold conveniently
