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.
1.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
2.Halley made his discovery ____.
A. by doing experiments
B. by means of his own careful observation
C. by using the working of other scientists
D. by chance
3.Halley made a surprising, but correct prediction in the year____.

4.This passage in general is about ____.
A. Halley and other scientists B. the orbit of a comet

Rich as a King
William 1, who conquered England some 930 years ago, had wealth, power and an army. Yet although William was very rich by the standard of his time, he had nothing like a flush toilet (抽水马桶), paper towels, or riding lawn mower (除草机). How did he get by?
History books are filled with wealthy people who were poor compared to me. I have storm windows, Croesus did not. Entire nations trembled before Alexander the Great, but he couldn’t buy cat food. Czar Nicholas lacked an electric saw.
Given how much better off I am than so many famous dead people, you’d think I’d be content. The trouble is that, like most people, I compare my wealth with that of living person: neighbors, school classmates, famous TV people. The greed I feel toward my friend Howard’s new kitchen is not reduced by the fact that no kings ever had a refrigerator with glass doors,
There is really no rising or falling standard of living. Over the centuries people simply find different things to feel sad about. You’d think that simply not having disease would put us in a good mood, but no we want a hot bath too.
Of course, one way to achieve happiness would be to realize that even by today’s standards the things I own are pretty nice. My house is smaller than the houses of many investment bankers, but even so it has a lot more rooms than my wife and I can keep clean.
Besides, to people looking back at our era from a century or two in the future, these bankers’ fancy counter tops and my awn worn Formica will seem equally shabby, I can’t keep up with my neighbors right now. But just wait.
1.What docs the underlined phrase “get by” in the first paragraph mean?
A. Succeed as a king.
B. Deal with complains.
C. Get some extra money.
D. Live in a satisfactory way.
2.How many historical figures are mentioned to compare lives in the past and present?
A. 3. B. 4.
C. 5. D. 6.
3.According to the passage, the author intends to .
A. tell us to be content with life
B. warn us to live in a simple way
C. leach us to learn lessons from life
D. encourage us lo struggle for wealth
4.What’s the author’s attitude towards life?
