三、阅读理解(共20小题，每题2分，满分40分)
阅读下列短文，从每题所给的四个选项(A、B、C、D)中，选出最佳选项。
A
The year is 2094. It has been announced that a comet (彗星) is heading towards the Earth. Most of it will miss our planet, but two pieces will probably hit the southern half of the Earth.
On 17 July , a piece four kilometers wide enters the Earth’s atmosphere with a massive explosion. About half of the piece is destroyed, but the remaining part hits the South Atlantic at 200 times the speed of sound. The sea boils and a huge hole is made in the sea bed. Huge waves are created and spread outwards from the hole. The wall of water, a kilometer high, rushes towards southern Africa at 800 kilometers an hour. Cities on the African coast are totally destroyed and millions of people are drowned.
Before the waves reach South America, the second piece of the comet lands in Argentina. Earthquakes and volcanoes are set off in the Andes Mountains. The shock waves move north into
10
California and all around the Pacific Ocean. The cities of Los Angeles, San Francisco and Tokyo are completely destroyed by earthquakes. Millions of people in the southern half of the earth are already dead, but the north won’t escape for long. Because of the explosions, the sun is hidden by clouds of dust, temperatures around the world fall to almost zero . Crops are ruined. The sun won’t
be seen again for many years. Wars break out as countries fight for food. A year later, no more than 10 million people remain alive.
Could it really happen? In fact, it has already happened more than once in the history of the Earth. The dinosaurs were on the Earth for over 160 million years. Then 65 million years ago they suddenly disappeared. Many scientists believe that the Earth was hit by a piece of object in space. The dinosaurs couldn’t live through the cold climate that followed and they died out. Will we meet the same end?
36．What is mainly described in the passage?
A．A historic discovery. B．An event of imagination.
C．A research on space. D．A scientific adventure.
37．When the first piece hits the South Atlantic, it causes .
A．an earthquake B．damages to cities
C．an Earth explosion D．huge waves
38．Why can’t the northern half of the earth escape for long?
A．Because the land is covered with water
B．Because the light and heat from the sun can not reach the earth.
C．Because people there can not live at the temperature of zero.
D．Because wars break out among countries .
39．By giving the example of dinosaurs, the author tries to prove .
A．animals could not live in the cold climate
B．what happened 65 million years ago was an invented story
C．the human beings will die out in 2094
D．the Earth could be hit by other objects in space
B
We often think of future. We often wonder what the world would be like in a hundred years’ time.
Think of space， perhaps a permanent(永久的) station on the moon will have been set up. Perhaps people will be able to visit the moon as tourists. Cheap rockets for space travel will have been developed，permitting long journeys throughout the solar system(太阳系). When that time comes， people will be taking holidays in space and visiting other planets. Great progress will have been made in medicine， too. Perhaps a cure will have been discovered for the most terrible
of all diseases—cancer. Pollution is a problem we must solve. In hundred’s years’ time it will have been controlled.
10
All the world will have been developed — even Antarctica. There will be large cities in Antarctica. We already have supersonic(超音速的) flight， but in a hundred years’ time we will have supersonic land travel as well.
We will have used up most of earth’s land to build our cities， so floating cities will have been built. The Japanese already have plans for cities of this kind. And there will be cities under the sea. The first of these will have been completed.
40. We will have developed ______ in a hundred years’ time， permitting long journeys all over the solar system.
A. cheap rockets for space travel B. a plane
C. a spaceship D. a satellite
41. Man will also have supersonic land travel ______ .
A. in a year B. about half a century later
C. in the year 2050 D. about a century later
42. The last paragraph mainly talks about ______ .
A. we’ll make good use of space on the earth
B. cities under the sea
C. Japan will first build floating cities
D. earth’s land is in danger
43. The best title for the passage is ______ .
A. Travel in the Future B. Future Life
C. Where to Live in the Future D. Space Travel
C
Some people are pessimistic(悲观的) when they think about the future. They say that，a hundred years from now， we will have used most of the earth’s resources. We will have polluted our seas badly，and be unable to eat fish from them. We will have made the air so dirty that we will need to wear masks. The world’s population will have doubled， and we will have used all the countryside for housing; there will be no farmland left.
Other people believe that Man adapts very easily. They have a different idea of the future. How， in their views，will people be living in a hundred years’ time？
One architect believes that Man will move off the land. He suggests that the city of the future will be a huge， pyramid-shaped building， which will be floating on the surface of the sea. About 5，000 families will be living there，and the building will contain shops and schools as well as homes. By living on the sea，we will give the farmers more land to grow crops.
As for oil，people will no longer need it: we will be heating our homes with power from the sun. And we will not be short of minerals， because there are plenty under our oceans. At the moment， we do not have the technology to get them out. But， in a hundred years’ time， the optimists say， the new sea cities will be using these resources.
What will be in the shops in the year 3000？ What will people be wearing？ How will people be traveling？
10
Scientists who make predictions about the future suggest that， by the year 3000， shops will no longer exist. Computers will have replaced them; and people will order goods from home.
People will be wearing very light, thin clothes. By this time, scientists will have invented a fabric that keeps us cool in hot weather and warm in cold weather.
As for travel， the experts say that most people will be using public transport. Electric cars will be traveling through the streets day and night. Anybody will be able to stop one and use it.
An interesting picture. Unfortunately, we will not be there to see if these predictions come true.
44. Pessimists believe that in the future ______ .
A. the seas and oceans will be full of houses
B. we’ll have used up all the resources
C. we will not have enough fish to eat from the seas
D. we will have polluted the air so badly that it will be impossible for us to breath
45. Optimists suggest that ______ .
A. all the land will be too polluted to be cropped on
B. pyramids will be the most commonly-used houses
C. people will be using the power from the sun instead of oil
D. we will be short of materials even though we get them from under the oceans
46. Scientists have made the predictions EXCEPT ______ .
A. electric cars will be going along the streets continuously
B. the resources under the oceans will never be used up
C. people will order from home
D. people won’t suffer from cold any longer
D
The new model is the highly interactive（互动的）learning model. We could also call it the conversational model, or the tutorial model. It is computer based, with the interaction between the student, or a small group of students, and learning programs are like the conversation between a student and a skilled tutor. Distance learning will be the main delivery method.
Student interaction with the learning material on the computer will use the student's natural language; it will seem like a conversation between a student and a human tutor. This is the key point of highly interactive, or conversational, learning units. Programs will ask questions in the student’s native language, and respond reasonably to free-form student input. Multiple choice and pointing will seldom be used; they often do not allow individualization (个体化) of education.
An important aspect of this model is that the computer will frequently store information about the student, about problems and about how far individual students have progressed. These records will be used often within the programs. Thus when a student returns to the learning activity, the computer knows about that student and knows where to begin the new part.
10
Global education is critical for the future, to get rid of poverty, corruption (腐败), violence and war, to solve major problems such as the lack of drinkable water, and to insure a happy life for all. Education should no longer be limited to the wealthy of the world, but should be available to everyone.
In the new distance learning environment learning can take place in markets, libraries, public buildings, learning centers, and the home. Gradually schools and universities will play a smaller role in learning, both because better learning can be delivered through such highly interactive material, and because such learning will be less costly for the individual student. Motivation (动机)is particularly important in a mastery-based distance learning, as the usual threats of traditional classrooms such as that of low grades are no longer possible,
Voice input will probably be the mode for this interaction. The new voice input systems from several companies are useful, cheap, and speaker independent in highly interactive learning. Keyboards may not be needed. Speech is a natural way for humans to communicate.
Students will work in small peer groups, about four. Other contacts with people, learning circles, will be possible, directly or electronically.
47. What is not the new model also called?
A. interactive model B. conversational model
C. tutorial model D. linguistic model
48. What does the model often use?
A. individualization of education
B. multiple choice and pointing
C. questions in students’ native language
D. fixed-form student input
49. What do computers detect students about?
A. Their future achievements B. Their intelligences
C. Their problems D. Their families
50. According to the passage, distance learning is ______ .
A. still expensive for ordinary students
B. will take place mainly in classrooms.
C. will play more role in students’ learning.
D. will still affect badly on the low-graded students
51. What is the Chinese for the underlined word “tutorial” in the firsr paragraph?
A. 辅导 B. 教具 C. 学费 D. 奖学金
E
Olaf Stapledon wrote a book called First and Last Men, in which he looked millions of years ahead. He told of different men and of strange civilizations, broken up by long 'dark ages' in between. In his view, what is called the present time is no more than a moment in human history and we are just the First Men . In 2, 000 million years from now there will be the Eighteenth or Last Men.
10
However, most of our ideas about the future are really very short-sighted. Perhaps we can see some possibilities for the next fifty years. But the next hundred? The next thousand? The next million? That's much more difficult.
When men and women lived by hunting 50, 000 years ago, how could they even begin to picture modern life? Yet to men of 50, 000 years from now, we may seem as primitive in our ideas as the Stone-Age hunters do to us. Perhaps through the spundels and ballalators, these words, which I have just made up, have to stand for things and ideas that we simply can't think of.
So why bother even to try imagining life far in the future? Here are two reasons. First unless we remember how short our own lives are compared with the whole human history, we are likely to think our own interests are much more important than they really are. If we make the earth a poor place to live, because we are careless or greedy or quarrelsome, our grand-children will not bother to think of excuses for us. Second, by trying to escape from present interests and imagine life far in the future, we may arrive at quite fresh ideas that we can use ourselves. For example, if we imagine that in the future men may give up farming, we can think of trying it now. So set you imagination free when you think about the future.
52. A particular mention made of Stapledon's book in the opening paragraph ______ ______
A. serves as a description of human history
B. serves an introduction to the discussion
C. shows a disagreement of views
D. Shows the popularity of the book
53. The text discusses men and women 50, 000 years ago and 50, 000 years from now in
order to show that ______ ___.
A. human history is extremely long
B. life has changed a great deal
C. it is useless to plan for the next 50 years
D. it is difficult to tell what will happen in the future
54. Spundels and ballalators are used in the text to refer to ______ ___.
A. tools used in farming
B. ideas about modern life
C. unknown things in the future
D. hunting skills in the Stone Age
55. According to the writer of the text , imagining the future will ______ ___.
A. serve the interests of the present and future generations
B. enable us to better understand human history
C. help us to improve farming
D. make life worth living

Dear Editor,
I’m a middle school student. I hear that a power station will be built near Mt. Yunxia, a place of interest. We know the power station will provide us with plenty of power and as a result, the local economy will develop rapidly, but many citizens and I are against the plan. To build the power station, many people will have to move away and a great number of trees will have to be cut
down. What’s worse, once the scenery of Mt. Yunxia is destroyed, it can never be restored. Therefore, this plan is not good for protecting the environment. We suggest the city government should think over this plan.
Yours faithfully,
Li Ping
