Two of them are【C2】______while the other six【C3】______from the sun than the earth is. The farther they are, the longer【C4】______they【C5】______around the sun. People noticed long ago that these traveling bodies moved around in the sky【C6】______definite paths. It is a【C7】______called gravity that【C8】______them in their paths. We know that every little bit of matter in the【C9】______pulls upon every other bit of mater. The pull between two bodies is【C10】______to the product of their masses. Because the sun is so large that pulls【C11】______the sun and the planets are thus great. If it【C12】______not for these pulls, the planets【C13】______off into space. In the same way【C14】______exists a pull between the earth and the moon, which keeps the moon【C15】______in its orbit around our planet, the earth. The gravity holds you to its surface, and pulls back to it the ball which you【C16】______into the air. Of course the ball also pulls【C17】______the larger earth, but the earth is so much larger that the pull【C18】______.

And they travel through a universe so large that one star seldom comes near to another. For the most part each star makes its journey in complete loneliness, like a ship on an empty ocean. The ship will be well over a million miles from its nearest neighbor. From this it is easy to understand why a star seldom finds another anywhere neat it. We believe, however, that some two thousand million years ago, another star wandering (漫游) through space, happened to come near our sun, Just as the sun and the moon raise tides (潮汐) on the earth, so this star must have raised tides on the surface of the sun. But they were very different from the small tides that are raised in our oceans; a large tidal wave must have travelled over the surface of the sun, at last forming a mountain so high that we cannot imagine it. As the cause of the disturbance (动荡) came nearer, so the mountain rose higher and higher. And before the star began to move away again, its tidal pull had become so powerful that this mountain was torn to pieces and threw off small parts of itself into space. These small pieces have been going round the sun ever since. They are the planets (行星). 第47题：Millions of stars are ________. [A] following a regular path in space [B] moving about without a fixed course [C] seldom wandering about in the universe [D] always travelling together

A．mustn't have B．haven't got C．don't need D．needn't

“In my opinion,” the first man said, “the Egyptian pyramids(埃及金字塔)are the world’s greatest wonder. Although they were built thousands of years ago, they are still standing. And remember: the people who built them had only simple tools. They did not have the kind of machinery that builders and engineers have today.” “I agree that the pyramids in Egypt are wonderful,” the second man said, “but I do not think they are the greatest wonder. I believe computers are more wonderful than the pyramids. They have taken people to the moon and brought them back safely. In seconds, they carry out mathematical calculations that would take a person a hundred years to do.” He turned to the third man and asked, “What do you think is the greatest wonder in the world？” The third man thought for a long time, and then he said, “Well, I agree that the pyramids are wonderful, and I agree that computers are wonderful, too. However, in my opinion, the most wonderful thing in the world is this thermos.” And he took a thermos out of his bag and held it up. The other two men were very surprised. “A thermos？” they exclaimed. “But that’s a simple thing.” “Oh, no, it’s not,” the third man said. “In the winter you put in a hot drink and it stays hot. In the summer you put in a cold drink and it stays cold. How does the thermos know whether it’s winter or summer？” 1. The underlined word “thermos” in Chinese means “_______”. A. 电冰箱 B. 洗衣机 C. 电风扇 D. 保温瓶 2. That the three men could not agree on what the world’s greatest wonder was because _______. A. they could not think of anything very wonderful B. they all had different ideas C. they could not prove that their opinions were right D. the journey ended too soon 3. The first man thought the pyramids were the most wonderful things in the world because ____. A. they were very beautiful B. they were Egyptian C. they had been built with very simple tools D. they could do mathematical calculations 4. The third man thought a thermos was the most wonderful thing in the world because _____. A. it lasted longer than the pyramids B. it cost less than a computer C. he thought it knew whether it was winter or summer D. the other two men were surprised when he told them about it 5. The third man was not very clever because ______.

The motorcar will undoubtedly change significantly over the next 30 yearn. It should become smaller, safer, and more economical, and should not be powered by the gasoline engine. The car of the future should be far more pollution-free than present types. Regardless of its power source, the auto in the future will still be the main problem in mi)an traffic congestion. One proposed solution to this problem is the automated highway system. When the auto enters the highway system, a retractable arm will drop from the auto and make contact with a mil, which is similar to those powering subway trains electrically. Once attached to the rail, the car will become electrically powered from the system, and control of the vehicle will pass to a central computer. The computer will then monitor all of the car's movements. The driver will use a telephone to dial instructions about his destination into the system. The computer will calculate the best mute, and reserve space for the car an the way to the correct exit from the highway. The driver will then be free to relax and wait for the buzzer that win warn him of his coming exit. It is estimated that au automated highway will be able to handle 10,000 vehicles per hour, compared with the 1,500 to 2,000 vehicles that can be carried by a present-day highway. One significant improvement in the future car will probably be ______ A．its power source B．its driving system C．its monitoring system D．its seating capacity
