閱讀下列短，從每題所給的四個(gè)選項(xiàng)(A、B、C、D)中，選出最佳選項(xiàng)。
A
The year is 2094. It has been announced that a coet (彗星) is heading towards the Earth. ost of it will iss our planet, but two pieces will probably hit the southern half of the Earth.
On 17 July , a piece four kiloeters wide enters the Earth’s atosphere with a assive explosion. About half of the piece is destroyed, but the reaining part hits the South Atlantic at 200 ties the speed of sound. The sea boils and a huge hole is ade in the sea bed. Huge waves are created and spread outwards fro the hole. The wall of water, a kiloeter high, rushes towards southern Africa at 800 kiloeters an hour. Cities on the African coast are totally destroyed and illions of people are drowned.
Before the waves reach South Aerica, the second piece of the coet lands in Argentina. Earthquakes and volcanoes are set off in the Andes ountains. The shock waves ove north into California and all around the Pacific Ocean. The cities of Los Angeles, San Francisco and Tokyo are copletely destroyed by earthquakes. illions 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, teperatures around the world fall to alost zero . Crops are ruined. The sun won’t
be seen again for any years. Wars break out as countries fight for food. A year later, no ore than 10 illion people reain alive.
Could it really happen? In fact, it has already happened ore than once in the history of the Earth. The dinosaurs were on the Earth for over 160 illion years. Then 65 illion years ago they suddenly disappeared. any scientists believe that the Earth was hit by a piece of object in space. The dinosaurs couldn’t live through the cold cliate that followed and they died out. Will we eet the sae end?
56．What is ainly described in the passage?
A．A historic discovery. B．An event of iagination.
C．A research on space. D．A scientific adventure.
57．When the first piece hits the South Atlantic, it causes .

C．a(chǎn)n Earth explosion D．huge waves
58．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 fro the sun can not reach the earth.
C．Because people there can not live at the teperature of zero.
D．Because wars break out aong countries .
59．By giving the exaple of dinosaurs, the author tries to prove .

B．what happened 65 illion years ago was an invented story
C．the huan 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’ tie.
Think of space， perhaps a peranent(永久的) station on the oon will have been set up. Perhaps people will be able to visit the oon as tourists. Cheap rockets for space travel will have been developed，peritting long journeys throughout the solar syste(太陽(yáng)系). When that tie coes， people will be taking holidays in space and visiting other planets. Great progress will have been ade in edicine， too. Perhaps a cure will have been discovered for the ost terrible
of all diseases—cancer. Pollution is a proble we ust solve. In hundred’s years’ tie it will have been controlled.
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’ tie we will have supersonic land travel as well.
We will have used up ost 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 copleted.
60. We will have developed ______ in a hundred years’ tie， peritting long journeys all over the solar syste.

Soe people are pessiistic(悲觀的) when they think about the future. They say that，a hundred years fro now， we will have used ost of the earth’s resources. We will have polluted our seas badly，and be unable to eat fish fro the. We will have ade the air so dirty that we will need to wear asks. The world’s population will have doubled， and we will have used all the countryside for housing; there will be no farland left.
Other people believe that an adapts very easily. They have a different idea of the future. How， in their views，will people be living in a hundred years’ tie？
One architect believes that an will ove off the land. He suggests that the city of the future will be a huge， pyraid-shaped building， which will be floating on the surface of the sea. About 5，000 failies will be living there，and the building will contain shops and schools as well as hoes. By living on the sea，we will give the farers ore land to grow crops.
As for oil，people will no longer need it: we will be heating our hoes with power fro the sun. And we will not be short of inerals， because there are plenty under our oceans. At the oent， we do not have the technology to get the out. But， in a hundred years’ tie， the optiists 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？ Hoill people be traveling？
Scientists who ake predictions about the future suggest that， by the year 3000， shops will no longer exist. Coputers will have replaced the; and people will order goods fro hoe.
People will be wearing very light, thin clothes. By this tie, scientists will have invented a fabric that keeps us cool in hot weather and war in cold weather.
As for travel， the experts say that ost 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 coe true.
64. Pessiists 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 fro the seas
D. we will have polluted the air so badly that it will be ipossible for us to breath
65. Optiists suggest that ______ .
A. all the land will be too polluted to be cropped on

C. people will be using the power fro the sun instead of oil
D. we will be short of aterials even though we get the fro under the oceans
66. Scientists have ade the predictions EXCEPT ______ .

The new odel is the highly interactive（互動(dòng)的）learning odel. We could also call it the conversational odel, or the tutorial odel. It is coputer based, with the interaction between the student, or a sall group of students, and learning progras are like the conversation between a student and a skilled tutor. Distance learning will be the ain delivery ethod.
Student interaction with the learning aterial on the coputer will use the student's natural language; it will see like a conversation between a student and a huan tutor. This is the key point of highly interactive, or conversational, learning units. Progras will ask questions in the student’s native language, and respond reasonably to free-for student input. ultiple choice and pointing will seldo be used; they often do not allow individualization (個(gè)體化) of education.
An iportant aspect of this odel is that the coputer will frequently store inforation about the student, about probles and about how far individual students have progressed. These records will be used often within the progras. Thus when a student returns to the learning activity, the coputer knows about that student and knows where to begin the new part.
Global education is critical for the future, to get rid of poverty, corruption (腐敗), violence and war, to solve ajor probles such as the lack of drinkable water, and to insure a happy life for all. Education should no longer be liited to the wealthy of the world, but should be available to everyone.
In the new distance learning environent learning can take place in arkets, libraries, public buildings, learning centers, and the hoe. Gradually schools and universities will play a saller role in learning, both because better learning can be delivered through such highly interactive aterial, and because such learning will be less costly for the individual student. otivation (動(dòng)機(jī))is particularly iportant in a astery-based distance learning, as the usual threats of traditional classroos such as that of low grades are no longer possible,
Voice input will probably be the ode for this interaction. The new voice input systes fro several copanies are useful, cheap, and speaker independent in highly interactive learning. Keyboards ay not be needed. Speech is a natural way for huans to counicate.
Students will work in sall peer groups, about four. Other contacts with people, learning circles, will be possible, directly or electronically.
67. What is not the new odel also called?
A. interactive odel B. conversational odel
C. tutorial odel D. linguistic odel
68. What does the odel often use?
A. individualization of education
B. ultiple choice and pointing
C. questions in students’ native language
D. fixed-for student inputwwxkb1.co
69. What do coputers detect students about?
A. Their future achieveents B. Their intelligences
C. Their probles D. Their failies
70. According to the passage, distance learning is ______ .
A. still expensive for ordinary students
B. will take place ainly in classroos.
C. will play ore role in students’ learning.
D. will still affect badly on the low-graded students
71. What is the Chinese for the underlined word “tutorial” in the firsr paragraph?
A. 輔導(dǎo) B. 教具 C. 學(xué)費(fèi) D. 獎(jiǎng)學(xué)金

Olaf Stapledon wrote a book called First and Last en, in which he looked illions of years ahead. He told of different en and of strange civilizations, broken up by long 'dark ages' in between. In his view, what is called the present tie is no ore than a oent in huan history and we are just the First en . In 2, 000 illion years fro now there will be the Eighteenth or Last en.
However, ost of our ideas about the future are really very short-sighted. Perhaps we can see soe possibilities for the next fifty years. But the next hundred? The next thousand? The next illion? That's uch ore difficult.
When en and woen lived by hunting 50, 000 years ago, how could they even begin to picture odern life? Yet to en of 50, 000 years fro now, we ay see as priitive in our ideas as the Stone-Age hunters do to us. Perhaps through the spundels and ballalators, these words, which I have just ade up, have to stand for things and ideas that we siply can't think of.
So why bother even to try iagining life far in the future? Here are two reasons. First unless we reeber how short our own lives are copared with the whole huan history, we are likely to think our own interests are uch ore iportant than they really are. If we ake the earth a poor place to live, because we are careless or greedy or quarrelsoe, our grand-children will not bother to think of excuses for us. Second, by trying to escape fro present interests and iagine life far in the future, we ay arrive at quite fresh ideas that we can use ourselves. For exaple, if we iagine that in the future en ay give up faring, we can think of trying it no So set you iagination free when you think about the future.
72. A particular ention ade of Stapledon's book in the opening paragraph ______ ______
A. serves as a description of huan history
B. serves an introduction to the discussion
C. shows a disagreeent of views
D. Shows the popularity of the book
73. The text discusses en and woen 50, 000 years ago and 50, 000 years fro now in
order to show that ______ ___.
A. huan history is extreely 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
74. Spundels and ballalators are used in the text to refer to ______ ___.
A. tools used in faring
B. ideas about odern life
C. unknown things in the future
D. hunting skills in the Stone Age
75. According to the writer of the text , iagining the future will ______ ___.
A. serve the interests of the present and future generations
B. enable us to better understand huan history
C. help us to iprove faring
D. ake life worth living

六、One possible version:
Dear Editor,
I’ a iddle school student. I hear that a power station will be built near t. Yunxia, a place of interest. We know the power station will provide us with plenty of power and as a result, the local econoy will develop rapidly, but any citizens and I are against the plan. To build the power station, any people will have to ove away and a great nuber of trees will have to be cut
down. What’s worse, once the scenery of t. Yunxia is destroyed, it can never be restored. Therefore, this plan is not good for protecting the environent. We suggest the city governent should think over this plan.
Yours faithfully,
Li Ping
