　　From boyhood he had been interested in astronomy(天文学), and while at Cambridge he would sit up at night to watch the stars. But he was not satisfied with the telescopes of those days because they didn't show him a clear picture of things. At first he thought there must be something wrong with the lens. But no matter how hard he tried to improve the lens; the trouble was still there.

　　This set Newton thinking. He began to study the nature of light and colors. In the end he found that sunlight, or white light, is actually made up of a row of colors. He counted seven colors in all. This was of course a great discovery. But Newton still wasn't satisfied His mind was busy with another problem. Before Newton's time, scientists had already discovered that the sun, not the earth, was the centre of the other planets moving round the sun. But they couldn't explain why this was so until Newton gave the answer.

　　One autumn evening while Newton was sitting under an apple tree thinking over these problems, he saw the moon rise in the sky. Why, he asked himself, should the moon go round the earth, never leaving the same path? At that moment, he heard an apple drop from the tree. Why didn't it go sideways or fly up?

　　There seemed to be only one reason：the earth was drawing it－that is the force of gravity. If a stone is tied to the end of a string and whirled around, it will fly round and round in circles because of the string. In the same way, the force of gravity, thought Newton, must be the force that keeps the moon going round the earth and the planets round the sun.

2．Which of the following is NOT true according to the passage?

[　　]

A．Newton made only two discoveries in his lifetime.

B．Finding nothing wrong with the lens, Newton began to study the nature of light and colors.

C．Nobody could explain why the planets moved round the sun before Newton's time.

D．It was by chance that Newton discovered the force of gravity.

3．Give the right order of the events given in the passage.

a．Newton found that the sunlight is made up of a row of colors.

b．Newton wondered why the apples didn't go sideways.

c．Newton concluded that the force of gravity keeps the moon going round the earth.

d．Newton tried every means to improve the lens.

e．Newton counted the number of colors.

[　　]

4．Which of the following is nearest in meaning to “They couldn't explain why this was so until Newton gave the answer.”?

[　　]

A．Newton gave the answer because they couldn't explain why.

B．Newton couldn't explain why unless they gave the answer.

C．It was Newton who gave the answer.

D．Newton was the first to give the answer.

Edmund Halley was an English scientist who lived over 200 years ago. He studied the observations of comets(彗星)which other scientists had made. The orbit（轨道） of one particular comet was a very difficult mathematical problem. He could not figure it out. Neither could other scientists who dealt with such problems.

However, Halley had a friend named Isaac Newton, who was a brilliant mathematician. Newton thought he had already worked out that problem, but he could not find the papers on which he had done it. He told Halley that the orbit of a comet had the shape of an ellipse(椭圆形).

Now Halley set to work. He figured out(解决，计算出)the orbits of some of the comets that had been observed by scientists. He made a surprising discovery. The comets that had appeared in the years 1531, 1607, and 1682 all had the same orbit. Yet their appearance had been 75 to 76 years apart.

This seemed very strange to Halley. Three different comets followed the same orbit. The more Halley thought about it, the more he thought that there had not been three different comets as people thought. He decided that they had simply seen the same comet three times. The comet had gone away and had come back again.

It was an astonishing idea! Halley felt certain to make a prediction(预言)of what would happen in the future. He decided that this would appear in the year 1758. There were 53 years to go before Halley’s prediction could be tested. In 1758 the comet appeared in the sky. Halley did not see it, for he had died some years before. Ever since then that comet had been called Halley’s comet, in his honor.

Edmund Halley figured out the orbit of ____.

A. some different comets appearing several times

B. the same comet appearing at different times

C. three different comets appearing at the same time

D. several comets appearing at the same time

Halley made his discovery ____.

A. by doing experiments

B. by means of his own careful observation

D. The orbit of a comet had the shape of an around.

Edmund Halley（哈雷）was an English scientist who lived over 200 years ago. He studied the observations of comets（彗星）which other scientists had made. The orbit（轨道）of one particular comet was a very difficult mathematical problem. He could not work it out. Neither could other scientists who dealt with such problems.

However, Halley had a friend named Newton, who was a brilliant（有才华的） mathematician. Newton thought he had already worked out that problem, but he could not find the papers on which he had done it. He told Halley that the orbit of a comet had the shape of an ellipse（椭圆）.

Now Halley set to work. He worked out the orbits of some of the comets that had been observed by other scientists. He made a surprising discovery. The comets that had appeared in the years 1531, 1607, and 1682 all had the same orbit. Yet their appearances had been 75 to 76 years apart（相隔）.

This seemed very strange to Halley. The different comets followed the same orbit. The more Halley thought about it, the more he thought that there had not been three different comets, as people thought. He decided that they had simply seen the same comet three times. The comet had gone away and had come back again.

It was an amazing idea! Halley felt certain enough to make a prediction（预言）of what would happen in the future. He decided that this comet would appear in the year 1758. There were 53 years to go before Halley’s prediction could be tested.

In 1758 the comet appeared in the sky. Halley did not see it, for he had died some years before. Ever since then that comet has been called Halley’s comet, in his honor.
