Passage Three
Many theories about the origin of the ocean have been proposed by scientists. The most widely accepted one is that the earth at some time in its very early history became hot enough to melt the materials from which it was formed. While in this molten state, lighter rock-forming materials (造岩材料) floated on the surface of the heavier ones. Then, between four and a half four billion (十亿) years ago, the molten earth cooled sufficiently to form. a crust of rock that was many miles thick.
Surrounding the earth was an unbroken canopy of clouds miles thick and made up mostly of water vapor. Rain falling toward the still-hot earth was heated to steam and rose to the clouds again. After many millions of years, as the earth continued to cool, its surface temperature fell below the boiling point of water. Rainwater could now remain on the earth, covering its whole surface except for the higher places on earth that had been formed from the lighter rock materials.
In 1970, scientists had pieced together evidence that the lighter rock materials had formed one huge continent by a vast ocean. Then, about 200 million years ago, the great continent began to break up, the pieces moving slowly apart.
The onrushing waters of the single huge ocean now entered and filled the spaces between the separating continents--and became the several oceans and seas we know today.

Passage Five
In order to learn a foreign language well, it is necessary to overcome the fear of making mistakes. If the primary goal (目标) of language use is communication (交际), then mistakes are secondary considerations that may be dealt with gradually. On the other hand, students should not ignore their mistakes. The language learner may observe how native speakers express themselves, and how native expressions differ from the way the learner might say them. For example, a Spanish speaker who has been saying "I do it" to express willingness to do something in the immediate future, could, by communicating with native speakers of English, observe that native speakers actually say "I'll do it". The result can serve as a basis for the student to change his way of using the present tense in English. But a student who is unwilling to communicate in the first place would lose this opportunity to learn by trial and error.
52. According to the passage, the present tense in English is ______.
Ⅳ. Reading Comprehension (60 points)
Directions: There are five reading passages in this part. Each passage is followed by four questions. For each question there are four suggested answers marked A, B, C and D. Choose one best answer and blacken the corresponding letter on the Answer Sheet.
Passage One
There was a nasty (肮脏的，卑鄙的) accident in our town not long ago, and I saw it happen. I was standing near a road which was under repair, not doing anything special—just watching the men at work. It was not far from the new motorway (高速公路) that runs past the town. It was an old road that used to be very busy—and dangerous before the motorway was built. Today, most cars use the new "superhighway" and the old road is pretty quiet, although cars do often come off the motorway into the town faster than they should.
Anyway, the men were repairing part of the road and there were signs up for at least 200 meters, telling everybody that the road was narrower than usual. Most of the drivers in both directions saw the signs and slowed down.
Then three cars came along close together, the third one moving at a very high speed. The first one pas sed the workmen and wanted to turn left. Meanwhile the third car came flying past the second one. The sec and car stopped. I think the driver knew something was going to happen. It did. The third car had no chance of stopping. Its driver braked (刹车) and pulled over to miss the first car and went right off the road.
There were four people in that car: a man, two women and a child. The child was a boy of nine. I read later that they were going shopping—just shopping, nothing more important than that. The driver was badly hurt. The little bay was hurt too. Both the women were killed immediately. One of them was the driver's wife and the other was the mother of the little boy. They never got to the shops.
36. The old road ______.
Passage Two
When we see well, we do not think about our eyes very often. It is only when we cannot see perfectly that we realize how important our eyes are.
People who are nearsighted can only see things that are very close to their eyes. Everything else is not so clear. Many people who do a lot of close work, such as writing, reading and sewing, become near sighted. Then they have to wear glasses in order to see distant (远处的) things clearly'.
People who are nearsighted suffer from just the opposite problem. They can see things that are far away, but they have difficulty in reading a book unless they hold it at arm's length. If they want to do much reading, they must get glasses, too.
Other people do not see clearly because their eyes are not exactly the right shape. They have what is called astigmatism (散光). This, too, can be corrected by glasses. Some people's eyes become cloudy because of cataracts (白内障). Long ago these people often became blind. Now, however, it is possible to operate on the cataracts and remove them.
Having two good eyes is important for judging distances. Each eye sees things from a slightly different angle (角度). To prove this to yourself, look at an object out of one eye; then look at the same object out
of the other eye. You will find the object's relation to the background (背景) and other things around it has changed. The difference between these two different eye views helps us to judge how far away an object is. People who have only one eye cannot judge distance as people with two eyes.
40. We should take good care of our eyes ______.
