题目内容

At the beginning of this century, medical scientists made an interesting discovery(发现): we are built not just of flesh (肌肉) and blood but also of time. They were able to show that we all have a ‘body clock’       us, which controls the       and fall of our body energies. It can       us different from one day to the next.
The idea of a ‘body clock’ should not be too       because the lives of most living things are controlled by the 24-hour night-and-day cycle (循环). We feel       and fall asleep at night. We become       and energetic during the day. Most people will have a bad feeling if the 24-hour cycle is      . For example, people who are not used to working at night can find that lack (缺少) of sleep causes them to     badly at work.
      the daily cycle of sleeping and waking, we also have other cycle which lasts longer than one day. Most of us would       that we feel good on some days and not so good on others; sometimes our ideas seem to be so active and at other times, they are not.

Yesterday and Today
Life in the twenty-first century will be different from life today. Between then and now many changes will take place, but what will the changes be?
The population is growing fast. There will be many people in the world and most of them will live longer than people live now.
Computers will be much smaller and more useful, and there will be at least one in every home. And computer studies will be one of the important subjects in schools then.
People will work fewer hours than they do now and they will have more free time for sports, watching TV and travel. Traveling will be much cheaper and easier. And many more people will go to other countries for holidays.
There will be changes in our food, too. More land will be used for building new towns and houses for all the people. Then there will be less room for cows and sheep, so meat will be more expensive. Maybe no one will eat it every day. Instead they will eat more fruit and vegetables. Maybe people will be healthier.

The World's Largest Insect
This giant insect can be used as a toy. A child ties one end of a string to a stick and the other end around the "neck" of an insect. Holding the stick, the child lets the insect go. With a loud whirring sound, the insect takes off, pulling the string in a large curve over the child's head. The child laughs as the stick jumps around. The child is African, and the toy is the African Goliath beetle, the largest insect in the world. 
The Goliath is a true insect because it has six legs and a body that is divided into three parts. Like all beetles, it has two pairs of wings. The front pair are thick and stiff and protect the back pair, which are soft. It is these soft back wings that make the beetle fly forward. They also cause the loud whirring sound the beetle makes when it flies. To steer, the beetle twists and turns its legs the same way you steer a bike by turning its front wheel. 
African children often use the Goliath beetle as a toy. Although it is over 15 centimeters long, it is quite harmless.

小题5: Where is the passage probably from ?
A.A story book .B.A newspaper.C.A student’s articleD.A science magazine .
English is very important in the modern world. Many people want to learn it well. Here are some things that I want to say about learning it.
To learn English well, you need two things-passion and good learning methods (方法). Passion is the more important one. Why? Because passion makes you want to learn English. Learning methods only tell you how to learn it better and faster.
If you love learning English, you will learn it regularly (有规律地) and spend much time on it. It will also be easy for you to remember new words and grammar rules. ________ For example, some people like history and know a lot about World War II. If you ask a person who doesn’t like history to memorize all the facts, he probably can’t do it.
When you don’t want to learn English, you can do the following things.
First, imagine that you can talk to native speakers just as you talk in your mother language. Imagine yourself to be a manager in a foreign company. Imagine you’re living in an English-speaking country.
Second, use English as much as possible. This is very important. The more you use English, the better you’ll learn it. English is very popular, so you can use it everywhere. You can watch American cartoons, write English diaries, and read interesting books written in English.
小题1:The underlined word “passion” means “______” in Chinese.
A.态度B.热情C.步骤D.情绪
小题2:The missing part in the Paragraph 3 can be ______.

“Yes, ladies and gentlemen, welcome aboard NASA’s Space Elevator. We’re going to leave soon. The entire ride will take about five hours, so sit back and enjoy the trip. As we rise, be sure to look out the window. You’ll see the sky change from deep blue to black. It is one of the most wonderful views(景色)you will ever see! ”
Does this sound like the Sci-Fi Channel? Well, it’s not. Scientists are thinking that a “space elevator” will be possible toward the end of the 21st century. A space elevator will consist of a long cable (电缆) from the Earth’s surface into space to an altitude(高度) of about 35,786 km. “Elevators” will travel along the cable and move people and loads between Earth and space. One of the greatest advantages is that the cost will be much less. Researchers estimate (估计) that a passenger with baggage at 150 kg might cost only $222! Compare that to today’s cost of around $3.3 million for the same weight. It would make “cheap” space travel possible. Scientists believe carbon nanotubes (纳米管) may be used to make high-strength materials for the cables, although they are still being studied.
It was Arthur C. Clarke who brought this idea to the general public. In his science fiction novel Fountains of Paradise, engineers build a space elevator on top of a mountain peak on an island. One day, Clarke was asked a question by a student during his speech. The student asked when the space elevator would become a reality. Clarke answered, “Probably about 50 years after everybody stops laughing.” He’s got a point. When we stop thinking of something as impossible, then we start working on its development.
小题1:Why should passengers in a space elevator look out the window while they are moving into space?
A.Because the blue sky is very beautiful.
B.Because the view outside is wonderful.
C.Because the sky changes from black to blue.
D.Because the trip will take about seven hours.
小题2:Which of the following is NOT true according to the passage?
A.Scientists haven’t used carbon nanotubes to make the cables.
B.Traveling in space elevators will cost much less in the future.
C.Passengers will be able to travel in space elevators with baggage.
D.Space elevators will travel for 35,786 km around the Earth’s surface.
小题3:What is the best title for this passage?
A.Possible Now: Space TravelB.Cheap Space Travel
C.Going into Space in an ElevatorD.Space Travel — Impossible
If you look at the sky one night and see something moving and shining that you have never seen before, it might be a comet (彗星).
  A comet sometimes looks like a star. Like a planet, a comet has no light of its own. It shines from the sunlight it reflects (反射). Like the earth, a comet goes round the sun, but on a much longer path (轨道) than the earth travels.
If a comet isn’t a star, what is it then?
    Some scientists think that a large part of a comet is water frozen into pieces of ice and mixed with iron and rock dust and perhaps a few big pieces of rock. When sunshine melts (融化) the ice in the comet, great clouds of gas go trailing after it. These clouds, together with the dust, form a long tail.Many people perhaps have seen a comet. However no one knows how many comets there are. There may be millions of comets, but only a few come close enough for us to see.
  An Englishman named Edmund Halley, who lived from 1656 to 1742, found out a lot about the paths that comets take through the sky. Some comets move out of our sight and never come back. Others keep coming back at regular times. A big comet that keeps coming back was named after Halley because he was the one who worked out when it would come back again. Maybe you have ever seen Halley’s Comets because the last time it came close to the sun and the earth was in the year 1986. Then people all over the world were outside at night to look at it. You will probably be able to see Halley’s Comets when it comes near the earth again.

WARNING: Holding a cell phone against your ear or putting it in your pocket may be bad for your health.   

This sentence is a warning that you’d better not put it close to you when a new phone is bought. Apple company, for example, doesn't want IPhones to come closer to you than 1.5 centimeters; Research In Motion, BlackBerry's producer, recommends 2.5 centimeters.
(1)If cell phone use can        health problems, the         will be very serious. Americans spend 2.26 trillion minutes chatting on cell phones every year, which brings $109 billion for the wireless businessmen.
Devra Davis, an epidemiologist(皮肤病专家) who has worked for the University of Pittsburgh, has published a book about mobile phone radiation(辐射)"Disconnect." Davis studies how often brain cancer happens during different age groups. She finds a big increase in brain cancer in the 20-to-29 age group and a drop for the older people.
Children are more easily hurt by radiation than grown-ups, Ms. Davis and other scientists point out. But no studies have yet been finished on cell phone radiation and children, she says.
Henry Lai, a research professor, began lab radiation studies in 1980 and found that mice exposed to(暴露在) radiofrequency(电波频率)radiation had destroyed DNA in their brains.
Ms. Davis recommends using wired earphones(有线耳机)or the phone's speaker. (2)Children should send text messages rather than call, she said, and pregnant(怀孕的) women should keep phones away from their bodies.
小题1:在(1)句空白处填入适当的词使句意完整、上下文通顺。
小题2:将(2)句翻译成中文。

小题4:找出同义句。
Scientists are still carrying on with the studies on cell phone radiation and children
小题5:找出或写出该短文的主题句。
It was a village in India. The people were poor but they were happy. After all, their forefathers had lived in the same way for centuries.
Then one day, some visitors from the city arrived. They told the villagers there were some people elsewhere who liked to eat frog. However, they did not have enough frogs of their own, and so they wanted to buy frogs from other places.
This seemed like money for nothing. There were millions of frogs in the fields around, and they were useless to the villagers. What they had to do was to catch them. Agreement was reached, and the children were sent into the fields to catch frogs. Every week a truck arrived to collect the catch and hand over the money. The villagers were able to dream of a better future. But the dream didn’t last long.
The change was hardly noticed at first, but it seemed as if the crops weren’t doing so well. More worry was that the children fell ill more often, and there were more insects around lately. The villagers decided that they couldn’t just wait to see the crops failing and the children getting weak. They would have to use the money earned to buy pesticides (杀剂) and medicine. Soon there was no money left.
The people realized what was happening. It was the frog. They hadn’t been useless. They had been doing an important job--- eating insects. Now with so many frogs killed, the insects were increasing more rapidly. They were damaging the crops and spreading diseases.
Now, the people are still poor. But in the evenings they sit in the village square and listen to sounds of insects and frogs. These sounds of the night now have a much deeper meaning.
