1. C

解析：本题问的是第一自然段的主旨大意，根据原文最后两句话：“Every living thing is different from each other. Every living thing is a unique combination of characteristics”可知，答案应选C。 2. D 解析：本题问的是为什么Gregor Mendel的工作尤其重要。根据文章第二自然段中“The work of Gregor Mendel was especially important to help us to answer these questions.”这句话及第三自然段对Gregor Mendel研究的介绍，我们可知Gregor Mendel发现了基因学说，这对人类来说非常重要，所以答案为D。 3.C 解析：本题问的是Gregor Mendel专门研究植物的原因。根据文章第二自然段中“Mendel was especially interested in the differences. He wondered why each plant was of certain color, shape, size.”这句话，我们可以得知他对植物具有不同的颜色、形状、大小很感兴趣，所以对其进行了研究，所以答案为C。 4. B

5

解析：本题问的是通过实验，Gregor Mendel证明了什么。根据文章第二自然段最后一句话“Mendel decided that pea plants carried factors, and the parents passed these factors onto their offspring.”我们可以得出他实验的结果，即豌豆拥有一些“因素”，而这些“因素”可以通过父母传给子女，所以答案选B。 5. A

解析：此题可用排除法来完成。B讲的是“基因只在植物中存在，动物没有”，很明显不正确。C讲的是“虽然世界上有很多不同的人，但是存在一些完全相同的人”，这与文章反复强调的“every person is unique”不符，所以不正确。D讲的是“在Gregor Mendel之后，一些生物学家发现基因不能够决定人的眼睛的颜色”，这在文章中没有提到，所以不正确。因此，正确答案只能是A，即“每一个人都是不同的，因为他们具有不同的基因”。

Unit 3

If you judge by the number of people who go to see the games and by the number of those who actually play it, basketball is probably the most popular sport in the United States today. It is mainly an indoor game, and the season extends from late autumn, through the winter, to early spring. There are many professional teams; but for the most part, basketball is a school sport. There is hardly a high school or college in the country that does not have its team.

In spring and summer, the most popular sport is baseball. During the warm weather, you can see young men and boys playing this game in any part of the country. Radio and television bring the details of the big games to every corner of that land, and the activities of the professional teams are a subject of conversation for Americans everywhere.

In autumn, the most popular sport is football. As you know, this is not the same kind of game that is so popular in other parts of the world. Like basketball and baseball, it is typically American, and those who have never seen it before have difficulty in seeing any sense in it. But for most people the game itself is not so important as the music and the cheering that go with it. On a cool bright autumn afternoon, there is nothing so colorful and exciting as a football game.

Pat O?Burke was a poor Irishman with a large family, and one morning, waking up very early from cold and hunger, he decided to go shooting in a wood near his cottage.

Suddenly he saw the owner, with a group of friends, coming towards him in the wood. There was a look of anger on Lord Northwood?s face as he caught sight of the gun in Pat?s hands. Pat?s heart sank with fear, but he saw there was no hope of escape, so he walked boldly up to the company and said to Lord Northwood, “Good morning, sir, and what has brought you out so early this morning?” Lord Northwood, rather surprised, said he and his friends were taking a little exercise to get an appetite for their breakfast. Then, looking at Pat with suspicion, he said, “But why are you out so early in the morning?” “Well, sir,” said Pat, “I just came out to see if I could
