    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.

    试题分析：这篇短文讲述的是科学家们最近发现了人的身体不仅是由肌肉和血液组成的，在人体里还有一个生物钟。它控制着我们的精力，有时候高涨，有时候低沉。
    小题1:考查介词及语境的理解。句意：科学家能够证明在我们的身体里我们都有一个生物钟。beside 在…旁边；inside 在…里面；outside 在…外面；under 在…下面。根据文意这里说的是在我们每个人的身体内部有一个生物钟，故选B。
    小题2:考查名词及语境的理解。句意：它（生物钟）控制着我们身体能量的起落。life 生活，生命；offer 提供；use 利用；rise上升。这里rise 和后面的fall是反义词，说的是人体里的生物钟控制我们身体能量的起落。故选D。
    小题3:考查动词及语境的理解。句意：它能使我们每天都不一样。show 表明，带领；treat对待； make 制造，制作；使；change 改变。前面提到人体的生物钟控制着人体的能量，所以会影响我们的心情，让我们的心情每天都不一样。故选C。
    小题4:考查形容词及语境的理解。句意：生物钟这个概念并不是太令人惊奇，因为大多数生物的生活都是由24小时的夜以继日的循环所控制的。difficult 困难的；natural 自然的；surprising 令人惊奇的；frightening令人害怕的。这里是说人们早就知道生物体的生活是被控制的，所以听到生物钟这个概念，人们并不会感到惊奇。故选C。
    小题5:考查形容词及语境的理解。句意：晚上我们会感到疲倦然后就睡觉。quiet 安静的；tired 累的，疲倦的；comfortable 舒适的；cheerful欢呼的。这里是说我们的人体都有生物钟来控制，到了晚上人们就会感到累了，要休息了，这是很自然的，故选B。
    小题6:考查形容词及语境的理解。句意：而白天的时候我们就会变得充满活力，精力充沛。regular 有规律的，定期的；serious 严肃的，认真的；lively 活泼的，有活力的；clear清楚的。这里是和上句话形成一个对比。由于有生物钟的控制，晚上我们会想要休息，那么白天则会精力充沛。故选C。
    小题7:考查动词及语境的理解。句意：如果这个24小时的循环被打扰了，大多数人都会感觉不好。disturb 打扰，打乱；push 推；restart 重新开始；trouble烦恼。这里做了一个假设，生物钟控制我们的身体，让它有规律的循环，但是这个循环被打乱的时候，人们就会有不好的感觉。故选A。
    小题8:考查动词及语境的理解。句意：例如，不习惯晚上工作的人可能会发现缺乏睡眠会导致他们在工作的时候表现不好。perform 表现，表演；suffer 遭受；count 数；control控制。这里是说生物钟被打乱的时候会影响人们的日常行为，所以工作的时候表现不好。故选A。
    小题9:考查介词及语境的理解。句意：除了睡觉和醒着这种日常的循环，我们还有另外一个循环，它的时间比一天还要长。with 有，和；as well as 除…之外；except 除了，不放在句首；rather than 不是。这里作者要给我们介绍我们身体里的另一种规律的循环。故选B。
    小题10:考查动词及语境的理解。句意：我们大多数人都会同意有时候我们感觉很好，但有时候又会感觉不好。afford 负担得起；admire 钦佩；advise 建议；agree同意。这里是我们大多数人都会有的体会，我们受人体生物钟的控制，有时候会感觉很好，有时候又感觉不好。故选D。

    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.

    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.
    Work in the future will be different, too. Dangerous and hard work will be done by robots. Because of this, many people will not have enough work to do. This will be a problem.

    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1:The African Goliath beetle is _______.  
    A．the world's largest insect
    B．a toy used in many parts of the world
    C．the only insect found in Africa

    小题2:What made the whirring sound that the child heard?

    A．makes a whirring sound when it flies
    B．has both soft and hard wings
    C．has six legs and a body with three parts
    D．can fly
    小题4: When flying, the Goliath steers by_______.

    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.
    小题1:A comet is like ________.
    A．sunB．moonC．sunlightD．the earth
    小题2:A large part of a comet is ______.
    A．water and rock
    B．water frozen into pieces of ice and mixed with iron
    C．ice, iron and rock dust
    D．only a few big pieces of rock
    小题3:Maybe many people _______.
    A．haven’t seen any cometsB．have seen all comets
    C．have seen a comet at daytimeD．have seen a comet
    小题4:Some comets keep coming back ________.
    A．at any timeB．at noonC．at regular timesD．at daytime
    小题5:Halley’s Comets came back _____.
    A．in 1990B．in 1980C．in 1986D．in 1989

    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.

    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.

    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.
    小题1:From Paragraph l, we learn that the villagers_______.
    A．worked very hard for centuries
    B．dreamed of having a better life
    C．were poor but somewhat happy
    D．lived a different life from their forefathers
    小题2:Why did the villagers agree to sell frogs?
    A．The frogs were easy money.
    B．They needed money to buy medicine.
    C．They wanted to please the visitors.
    D．The frogs made too much noise.
    小题3: What might be the cause of the children’s sickness?
    A．The crops didn’t do well.B．There were too many insects.
    C．The visitors brought in diseases.D．The pesticides were overused.
    小题4:What is meaning of the last sentence of the article?
    A．Happiness comes from peaceful life in the country.
    B．Money is important.
    C．The harmony between man and nature is important.
