題目列表(包括答案和解析)

Agence Rrance-Presse--- French doctors this week carried out the world’s first operation on a human in zero gravity, using a specially adapted aircraft to create conditions in space.

During a three-hour flight from Bordeaux in southwest France, the team of surgeons and anesthetists (麻醉師) successfully removed a benign tumor (良性瘤) from the forearm of a 46-year-old volunteer. The experiment was part of a program backed by the European Space Agency to develop techniques for performing robotic surgery aboard the International Space Station or at a future Moon base.

“Now we know that a human being can be operated on in space without too many difficulties,” says the team leader Dr. Dominique Martin.

Under normal ground conditions, the operation would be performed under a local anesthetic. Without gravity, the surgeon’s work is harder and the patient’s body reacts differently. Blood doesn’t pump in the same way.

The custom-designed Airbus 300 aircraft performed a series of parabolic swoops (拋物線飛行), each creating between 20 seconds of weightlessness. The process was repeated 32 times.

Fixed inside a custom-made operating block, three surgeons and two anesthetists worked during these periods, with their instruments held in place with magnets around the patient’s bed. The next part of the program is to carry out a remote-controlled operation using a robot controlled from the ground by satellite. This experiment should take place within a year, Martin says.

Anesthetist Dr. Laurent de Coninek says that zero-gravity surgery offers huge promise for space exploration, although it would at first be limited to treating simple injuries. Today more than 400 people have already traveled into space. The chances of injuries occurring during missions will become even greater and to bring a wounded person back to the earth for treatment is both risky for them and expensive.

67. What would be the best title for the test?

A. A Special Operation for Doctors            B. First Operation on the Moon

C. World’s First Operation in Zero Gravity      D. An Important Experiment for Doctors

68. What’s the purpose of the operation?

A. To have an experiment on space operation.    B. To cure the patient.

C. To do it at the request of the patient.               D. To reduce the danger of operation on earth.

69. It is difficult for doctors to do operations in space because________________.

A. the patient’s illness will be more serious           B. the patient has no feeling about pain

C. the patient’s body reacts differently               D. the patient’s flood will stop flowing

70. The last paragraph mainly wants to tell readers________________.

A. there are many people injured in space           B. it is necessary to do the experiment

C. it is risky to travel in space                             D. there is no need to bring patients in space to the earth

Brenda Bongos was a happy, artistic girl. She had one big ambitionto play the drums in a band. But one big obstacle lay in her way. To be good enough to play in a band, Brenda had to practice a lot, but she lived next-door to a lot of old people. Many of them are sick. She knew that the sound of beating drums would really get on their nerves. So, she had tried playing in the strangest places: a basement, a kitchen, and even in a shower. But there was always someone it would annoy.

One day, while watching a science documentary on TV, she heard that sound cannot travel in space, because there's no air. At that moment, Brenda Bongos decided to become a sort of musical astronaut.

With the help of a lot of time, books and work, Brenda built a space bubble. This was a big glass ball connected to a machine which sucked out all the air inside. All that would be left inside was a drum kit (成套設(shè)備)and a chair. Brenda got into the space suit she had made, entered the bubble, turned on the machine, and played those drums like a wild child.

It wasn't long before Brenda Bongos came very famous. Many people came to see her play in her space bubble. Shortly afterwards she came out of the bubble and started giving concerts. Her fame spread so much that the government suggested that she be part of a unique space journey. Finally, Brenda was a real musical astronaut, and had gone far beyond her first ambition of playing drums in a band.

Years later, when asked how she had achieved all this, she thought for a moment, and said: "If those old people next - door hadn't mattered so much to me, I wouldn't have found a solution, and none of this would have ever happened."

1.Why did Brenda try to play in the strangest places?

A. Because she didn't mean to disturb others.

B. Because she didn't want others to hear her play.

C. Because she didn't have her own room.

D. Because she didn’t like her neighbors.

2.Brenda started to give concerts _______.

A. when people came to see her in the space bubble

B. when she became part of the unique space journey

C. after she became a real musical astronaut

D. after she practiced in her space bubble

3.Brenda became famous because _______.

A. she was good at music and science

B. she invented a special way of practice

C. she became a real musical astronaut

D. she played well and had a talent

4.Which of the following can be used to describe Brenda?

A. Lovely, brave and kind.

B. Brave, kind and hardworking.

C. Kind, hardworking and clever.

D. Nervous, kind and clever.

I love science and science fiction. Like many science fiction fans, I am fascinated by the possibility of time travel. However, one must combine romance with reasoning and look into the chances of time travel critically.

First of all, we must remember the whole universe is in motion. If we want to go back to yesterday, our "time machine" has to move back in time and space. If someone claimed he was at home when he suddenly travelled 200 years back in time, he either had an illusion or made the story up. Two hundred years ago, Earth was in a different place in space, so how can you travel back 200 years without moving in space? Don't get me wrong. I am not knocking the genius of science fiction writers. H.G. Wells's "The Time Machine" is a great work of fiction, but that’s all. I have read many other time travelling science fiction stories since reading H.G. Wells, but none address this problem of displacement.

My own argument for the impossibility of time travel is that physical states of the past no longer exist and those of the future are not here yet. To be able to move back and forth in time requires everything that has happened, is happening, and will happen everywhere in the whole universe at every single moment in time-past, present, and future-to be stored as a "reality" somewhere-like the save game file of a computer game that contains every single byte of information of the game at the point it was saved, but you would need an almost extremely large file and almost extremely many of them-so it can be re-entered and communicated with, and not just light signals for viewing. To me, I don’t buy it.

1.Which of the following can be the best title?

    A. How to make time travel possible?

    B. Why am I fascinated by time travel?

    C. Why do I think time travel is not possible?

    D. How to explain the possibility of time travel?

2.What’s the meaning of the underlined word “illusion”?

    A. success          B. dream                C. switch               D. support

3. According to the author, which of the following is RIGHT?

    A. We can go back to the past by time travel.

    B. People can travel to the future by moving in space.

C. “The Time Machine” is nothing more than a science fiction.

    D. Everything that happened, is happening and will happen can be stored somewhere.

4.In the author’s opinion, time travel might be possible if                            .

    A. people could combine romance with reasoning

    B. people could stop the movement of the whole universe

C. people could use time machine under the instruction of H.G. Wells

    D. people could “save” everything in the past, present and future in a certain space

“Why should I care about the environment?” some people ask. There is a very simple reason: We live on the earth, and it is the only place we can live on right now, as we cannot live in space yet. If we treat the earth like a garbage dump, it will become dirty and unlivable. If we treat it well by being eco-conscious, the earth will stay clean and suitable for living, for ourselves and for our children.
What is “being eco-conscious”?
Being eco-conscious means being aware of your actions, and what you do to the environment. For example, you might think, “Using hairspray is great for fixing my hair.” However, if you are eco-conscious, you would ask, “Does this hairspray have CFCs in it? Could I be destroying the earth by using hairspray?”
How can I be eco-conscious?
You can find many simple ways to help the environment in your everyday life.
When you go shopping, bring a bag or a basket with you. Please try not to use plastic bags as much as you can.
You can go to work by bike or on foot if it is not far from your home.
You can put your rubbish into different bags, which makes it convenient for recycling.
You can eat less chewing gum.
You can use your own chopsticks instead of the disposable ones in your company or in restaurants.
You can put batteries in a special box instead of in garbage bins.
You can use the water which has been used for washing vegetables or fruits to clean the floor and the toilet or to water your garden.
You can turn off the decorative lights in your room when watching TV.
You can turn down your air conditioner by one degree, as this will cause a 10% reduction in energy use.
You can use recycled paper. Every ton of recycled office paper saves 380 gallons of oil. You can also use recycled glass instead of glass made from raw materials. This will reduce the related air pollution by 20%, and the related water pollution by 50%.
Please believe that. If you do a little, it will make a big difference.
【小題1】Human beings should care about the environment because _________ .

A.if we make the earth unlivable, we’ll have to live in space
B.it can help our children live better
C.if we don’t, the earth will become a garbage dump
D.it will help to make the world a good living place
【小題2】If your deskmate is an eco-conscious person, he should __________.
A.be aware of the importance of protecting the environment
B.use plastic bags when he buys something
C.know nothing about CFCs
D.turn his air conditioner to a higher degree
【小題3】If you want to help the environment, you should do all the following EXCEPT ________.
A.share a car with your colleagues
B.use paper bags instead of plastic bags
C.use hairspray containing CFCs
D.use recycled glass instead of glass made from raw materials
【小題4】It can be inferred from the passage that _________.
A.it’s very hard for human beings to keep the earth clean and comfortable
B.protecting the environment is the duty of everybody
C.we should protect the environment together, as it’s no use doing it individually
D.it’s very easy to be eco-conscious
【小題5】According to the author, which of the following statements is WRONG?
A.Being eco-conscious means you should know much about the environment.
B.The more we care, the better the environment will be.
C.If each of us just does a little, we can’t make any difference.
D.If we treat the earth badly, we’ll make a lot of trouble for ourselves.

第二部分 閱讀理解(共兩節(jié),滿分40分)
(共15小題;每小題2分,滿分30分)
閱讀下列短文,從每題所給的四個(gè)選項(xiàng)(A、B、C和D)中,選出最佳選項(xiàng),并在答題卡上將該項(xiàng)涂黑。
A
In 1901, H.G. Wells, an English writer, wrote a book describing a trip to the moon. When the explorers(探險(xiǎn)者)landed on the moon, they discovered that the moon was full of underground cities. They expressed their surprise to the “moon people” they met. In turn, the “moon people” expressed their surprise. “Why,” they asked, “are you traveling to outer space when you don’t even use your inner space?”
H.G. Wells could only imagine travel to the moon. In 1969, human beings really did land on the moon. People today know that there are no underground cities on the moon. However, the question that the “moon people” asked is still an interesting one. A growing number of scientists are seriously thinking about it.
Underground systems are already in place. Many cities have underground car parks. In some cities, such as Tokyo, Seoul and Montreal, there are large underground shopping areas. The “Chunnel”—a tunnel(隧道)connecting England and France, is now complete.
But what about underground cities? Japan’s Taisei Corporation is designed a network of underground systems, called “Alice Cities.” The designers imagine using surface space for public parks and using underground space for flats, offices, shopping, and so on. A solar dome(太陽能穹頂)would cover the whole city.
Supporters of underground development say that building down rather than building up is a good way to use the earth’s space. The surface, they say, can be used for farms, parks, gardens, and wilderness. H.G. Wells’ “moon people” would agree. Would you?
36.. The explorers in H. G. Wells’ story were surprised to find that the “moon people” ____.
A. knew so much about the earth
B. understand their language
C. lived in so many underground cities
D. were ahead of them in space technology
37.. What does the underlined word “it ”(paragraph 2)refer to?
A. Discovering the moon’s inner space.
B. Using the earth’s inner space.
C. meeting the “moon people ”again.
D. Traveling to outer space.
38.. What sort of underground systems are already here with us?
A. Offices, shopping areas, power stations.
B. Tunnels, car parks, shopping areas.
C. Gardens, car parks, power stations.
D. Tunnels, gardens, offices.
39.. What would be the best title for the text?
A. Alice Cities-cities of the future
B. Space travel with H.G. Wells
C. Enjoy living underground
D. Building down, not up
