五、本讲重点知识讲解：
Dinosaurs are extinct now. Scientists are always wondering about the cause of their extinction. This proves to be difficult, but scientists are still working on it.
It is reported that there is a huge hole in the ground in eastern Mexico. This hole was believed to be caused by a large object that fell from space sixty-five million years ago. At about the same time, dinosaurs living on the ground disappeared. Though it is proved that this large object had a close relation with the death of dinosaurs and other animals, scientists have different opinions upon how the large object led to the death of the ancient animals.
译文：
恐龙现在已经绝迹了。科学家们一直想搞清楚它们绝迹的原因。这不是一件容易的事情，但是科学家们依然在努力。
据说在墨西哥东部有个巨大的坑，人们认为这个坑是由6500万年前从外太空中陨落的巨大物体造成的。在那时候，生活在陆地上的恐龙就绝迹了。因此，人们认为那个巨大的物体可能是导致恐龙死亡的原因。尽管已证实这个巨大的物体和恐龙及其他动物的灭绝有密不可分的关系，但科学家们对这一物体如何导致这些远古动物的灭绝仍持有不同的意见。
Twenty years ago, scientists discovered that a large cloud of dust was created by the crash of the large object. They reasoned that sunlight was stopped from reaching the earth by the cloud. As a result, the weather became very cold. The cold weather and less sunshine killed many plants which were the food of dinosaurs and other animals. Because of no food the animals soon died.
译文：
20年前，科学家们发现这个巨大的物体与地面碰撞后会产生一个巨大的尘雾团，从而阻碍了太阳光照射地面。因此，天气变得非常冷。寒冷的天气和缺少阳光使很多植物死亡，而这些植物正是恐龙和其他生物赖以生存的食物。因为没有食物，这些动物很快就死亡了。
About ten years ago, when scientists from the United States and Mexico found that the large object caused a huge hole in Mexico, some scientists raised another theory. They said that the object was not big enough to create a deadly cloud of dust, but it hit with such great force that poisonous chemicals were released. Dinosaurs and other ancient animals were poisoned by the chemicals and then died.
译文：
大约10年前，美国和墨西哥的科学家们发现这个巨大的物体在墨西哥砸出的一个大坑。一些科学家又提出了另一种理论。他们说这个物体还没有大到能够产生致命的尘雾团的地步，但认为物体的强烈撞击致使其散发出有毒的化学物质。恐龙和其他的生物就是被这些有毒的化学物质毒死的。
Which of the two views is more reasonable, the first or the second? Maybe both. In order to test their discoveries, scientists are preparing to make a study of the rocks that remain after the large object hit. They hope that in the future we will have a better understanding of any chemical reactions which have influenced the environment.
译文：
这两种观点哪一种更有道理呢？是第一种还是第二种？可能两个都有道理。为了验证他们的发现，科学家们准备研究巨石撞击地面后保留下来的岩石。他们希望未来我们能够对损害环境的化学反应有更多的了解。

【典型例题】
阅读与表达
阅读短文，根据其内容回答问题
Gone are the days when men and women couldn’t associate (交往) with each other. When we are asked whether boys and girls can associate with each other, most of us will say, “Yes, of course. Why not?”
If we want to deal with the association between boys and girls properly, here are some “dos and don’ts” for you to follow.
①Keep a normal and healthy state of mind（心态）. Our schools and classes are made up of boys and girls. It is very natural for boys and girls to contact each other and build up the friendship with the students of the other sex. Generally speaking, we should broaden the circle of the association. We should make as many friends as possible. We should have more friends of the other sex instead of one or two. We should contact the students in public instead of in secret.
②Contact students of the other sex warmly, generously and sincerely. Don’t be too nervous or too shy in contact with a person of the other sex. In that case it is very difficult for you to make a lot of friends, as no one likes a person who is too shy to say a word. If you are too shy a person, you can also find a way out. First of all, you can contact the students with the same interest and hobby with you. As both of you have much in common, you may have much to talk about. If you keep doing like that, little by little, you will gladly find you are also as free to express yourself as others.
③Don’t fall into the ditch（泥潭）of early love. The boys and girls at adolescence (青春期) are rich in feeling and full of imagination. They are easy to regard the friendship as a sign of love and fall in love with each other at an early age. In my opinion, boys and girls at middle school are too young and too tender to shoulder the heavy duty of love. Early love is a green apple that can’t be eaten. An apple won’t taste sweet until it is fully ripe (成熟). Do keep out of early love.
1. Should boys and girls contact each other in public or in secret?
______________________________________________________________________
2. What does the underlined sentence in the 3rd paragraph mean?
_________________________________________________
3. Does the writer think the boys and girls at adolescence should have early love?
______________________________________________________________________
4. How many tips does the writer give us?
______________________________________________________________________
5. What’s the purpose of writing this passage?
_____________________________________________________________________

In the United States, when you become rich you want people to know about it. And even if you do not become very rich you want people to think that you are. That is what “keeping up with the Joneses” is about. It is the story of someone who tried to look as rich as his neighbors.
The expression was first used in 1913 by a young American called Arthur Momand. He told this story about himself. He began earning $125 a week at the age of 23. That was a lot of money in those days. He got married and moved with his wife to a very wealthy neighborhood outside New York City. When he saw that rich people rode horses, Momand went horseback riding every day. When he saw that rich people had servants, Momand and his wife also hired a servant and gave big parties for their new neighbors.
It was like a race, but one could never finish this race because one was always trying to keep up. The race ended for Momand and his wife when they could no longer pay for their new way of life. They moved back to an apartment in New York City.
Momand looked around him and noticed that many people do things just to keep up with the rich lifestyle of their neighbors. He saw the funny side of it and started to write a series of short stories. He called it “Keeping up with the Joneses” because “Jones is a very common name in the United States. “Keeping up with the Joneses” came to mean keeping up with the rich lifestyle of the people around you. Momand’s series appeared in different newspapers across the country for over 28 years.
People never seemed to get tired of keeping up with the Jonese
