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.

解析

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。

Oil is so important that it is sometimes called “black gold”. Almost half of our energy comes from oil. We use it to run our cars and factories and to heat our homes, offices and schools. Many everyday things are made from oil. Your shirt may have oil in the material. The soap you wash your hands with might also be made from oil. Your favorite plastic toy is made from oil.
Oil is hard to find, because it is trapped deep under the earth. Once the only way people knew there was oil someplace if it leaked（渗漏）out of the ground. Today, however, we have many ways of finding oil. One tool measures（测量）the pull of gravity. Places where gravity is weaker are more likely to have oil. Another tool is sound waves（声波）. Sound waves travel through different kinds of rocks at different speeds. We can use them to find the rocks that have oil in them.
We need a lot of oil, and we are using up the oil wells we know about. Soon we must find new ways of looking for this “black gold”.
小题1:Which of the following isn’t the way to help find oil?

A．Sound waves travel through different kinds of rocks at different speeds.

B．People measure the pull of gravity to know if there is oil.

C．Sound waves tell us where the oil has leaked out of the ground.

D．People know there is oil if it leaks out of the ground.

小题2:Which of the following does the passage lead you to believe?

A．Oil was firstly found by measuring gravity.

B．Many things are made from oil.

C．We will never run out of oil.

D．Our lives would not be different if we didn’t have oil.

小题3:The main idea of the whole story is that ________________.

A．many things are made from oil

B．we must find new ways of looking for oil

C．people spend a lot of time looking for oil

D．oil is important for us but hard to find

"Here"s the advance payment(预期款) of 10,000 dollars. You will get the other half when we get those papers," the agent told Mike. "But sir, Mr. Smith has been very suspicious (怀疑) since last week," Mike replied.
"In that case, be careful and don"t worry. You are very clever," the agent said." Take 5,000 dollars more," Mike looked around uneasily but took the money.
Mike was a clerk in a large company. A few years ago he started to get very worried because it was very hard for him to support his family. He wanted to give his child an excellent education and a bright future, but the future looked rather hopeless.

Carmen Arace Middle School is situated in the pastoral town of Bloomfield, Conn., but four years ago it faced many of the same problems as inner-city schools in nearby Hartford: low scores on standardized tests and dropping enrollment（入学注册）. Then the school’s hard-driving headmaster, Delores Bolton, persuaded her board to shake up the place by buying a laptop computer for each student and teacher to use, in school and at home. What’s more, the board provided wireless Internet access at school. Total cost: $2.5 million.
Now, an hour before classes start, every seat in the library is taken by students who cannot wait for getting online. Fifth-grade teacher Jen Friday talks about different kinds of birds as students view them at a colorful website. After school, students on buses pull laptops from backpacks to get started on homework. Since the computer arrived, enrollment is up 20%. Scores on state tests are up 35%.
Indeed, school systems in rural Maine and New York City also hope to follow Arace Middle School’s example. Governor Angus King had planned using $50 million to buy a laptop for all of Maine’s 17,000 seventh-graders – and for new seventh-graders each fall.
In the same spirit, the New York City board of education voted on April 12 to create a school Internet portal（入口）, which would make money by selling ads and licensing public school students. Profits（盈利）will also provide e-mail service for the city’s 1.1 million public school students. Profits will be used to buy laptops for each of the school system’s 87,000 fourth-graders. Within nine years, all students in grades 4 and higher will have their own computers.
Back in Bloomfield, in the meantime, most of the kinks have been worked out. Some students were using their computers to visit unauthorized（非法的）websites. But teachers have the ability to keep an eye on where students have been on the Web and to stop them. “That is the worst when they disable you,” says eighth-grade honors student Jamie Bassell. The habit is rubbing off on parents. “I taught my mom to use e-mail,” says another eighth-grader, Katherine Hypolite. “And now she’s taking computer classes. I’m so proud of her!”
小题1:The example of Carmen Arace Middle School in the passage is used to ______.

A．show the problems schools are faced with today

B．prove that a school without high enrollment can do well

C．express the importance of computers in modern education

D．tell that laptops can help improve students’ school performance

A．enjoy e-mail service in the near future

B．make money by selling ads on websites

C．all have their own laptops within nine years

D．become more interested in their studies with laptops

小题3:The underlined word “kinks” in the last paragraph most probably means ______.

A．plans

B．projects

C．problems

D．products

小题4:From the passage we learn that ______.

A．a school Internet portal is the key to a laptop program

B．the laptop program also has a good influence on parents

C．students slowly accept the fact their online activities controlled

D．the laptop program in public school is mainly for the eighth-graders

“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 Travel	B．Cheap Space Travel
C．Going into Space in an Elevator	D．Space Travel — Impossible
