Passage Three 3
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 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 the orbits of some of the comets that had been observed by scientists. He made a surprising discovery. The comets that appeared in the years 1531,1607, and 1682 all had the same orbit. Yet their appearances had been 75 to 76 years apart.
This seemed very strange to Halley. Three different comets followed the same
A. Halley and other scientists
B. the orbit of a comet
C. Newton and Halley
D. Halley and his discovery

Passage Three
Most English people have three names: a first name, a middle name and the family name. Their family name comes last. For example, my full name is Jim Allan Green. Green is my family name. My parents gave me both of my other names.
People don’t use their middle names very much, So "John Henry Brown" is usually called "John Brown". People never use Mr. , Mrs. or Miss before their first names. So you can say John Brown, or Mr. Brown; but you should never say Mr. John. They use Mr. , Mrs. or Miss with the family name but never with the first name.
Sometimes people ask me about nay name. "When were you born, why did your parents call you Jim" they ask. "Why did they choose that name" The answer is they didn’t call me Jim. They called me James. James was the name of nay grandfather. In England, people usually call me Jim for short. That’s because it is shorter and easier than James.
A. one
B. two
C. three
D. four
Passage Two
Most English people have three names: a first name, a middle name and the family name. Their family name comes last. For example, my full name is Jim Allan Green. Green is my family name. My parents gave me both of my other names.
People don’t use their middle names very much. So" John Henry Brown" is usually called "John Brown". People never use Mr.; Mrs. or Miss before their first names. So you can say John Brown, or Mr. Brown; but you should never say Mr. John. They use Mr. , Mrs. or Miss with the family name but never with the first name.
Sometimes people ask me about my name. "When were you born, why did your parents call you Jim" they ask. "Why did they choose that name The answer is they didn’t call me Jim. They called me James. James was the name of my grandfather’. In England, people usually call me Jim for short. That’s because it is shorter and easier than James.
