题型：不详难度：来源：
In the past, there were eight kinds of tigers in the world. But during the 20th century, only five were left. The number of Siberian tigers (东北虎) was about 300, but now it is less than 22. They’re in danger of dying out. If the government does nothing, we won’t be able to see them in ten to twenty years.
In order to stop people from hunting and killing wild tigers, and in order to make wild tigers more, the World Wildlife Fund (世界自然基金会) has started a program (项目) recently (最近). China and twelve other countries joined it.
However, it’s not enough. Remember that nature is a food chain (链). If we hurt and kill too many wild deer and pigs, wild tigers will die out because of hunger (饥饿). So the most important thing is to save the animals that tigers eat. In order to protect the wild tigers, we need call on (号召) more people to stop eating, hunting and killing wild animals.

答案
小题1:A
小题2:C
小题3:D
小题4:B
小题5:A
解析
试题分析：老虎是强大而危险的动物，但现在它们正处于危险之中。他们面临灭绝的危险。记住,自然界是食物链。如果我们伤害和***死太多野生鹿、猪，野生老虎会因为饥饿消亡。所以最重要的是拯救老虎赖以为食的动物。为了保护野生老虎,我们需要停止进食,狩猎和***害野生动物。
小题1:细节理解题。 由“In the past, there were eight kinds of tigers in the world. But during the 20th century, only five were left. （在过去,世界上有八种老虎。但是在20世纪,只剩下五种。）”原来有8种，现在只剩5种了，所以有三种灭绝了，故选A。
小题2:细节理解题。由“The number of Siberian tigers (东北虎) was about 300, but now it is less than 22.（以前西伯利亚虎的数量(东北虎)约为300,但现在还不到22只。）”由此可推算出，有93%的东北虎死去了。故选C。
小题3:细节理解题。由“Remember that nature is a food chain . If we hurt and kill too many wild deer and pigs, wild tigers will die out because of hunger .(记住,自然界是食物链。如果我们伤害和***死太多野生鹿、猪，野生老虎会因为饥饿消亡。)”老虎以食物链中的猪和鹿为食，没有足够的猪和鹿，就会危及老虎的生存，故选D。
小题4:细节理解题。由“the World Wildlife Fund (世界自然基金会) has started a program (项目) recently (最近). China and twelve other countries joined it.”可知，是中国和12个其他国家参与了世界自然基金会组织的某个项目，而不是只有12个国家加入世界自然基金会，故选B。
小题5:主题归纳题。根据文章的介绍可知，作者主要描述了老虎的处境和人们如何采取措施保护老虎，所以选 A（最佳题目是：为何和如何保护老虎）。

This is an old English saying (谚语). It means that we should go to bed early at night and get up early in the morning. If we do, we shall be healthy. We shall also be rich and clever.
Is this true? Perhaps it is. The body must have enough sleep. Children of your age need ten hours’ sleep every night. If you go to bed late, you can’t have enough sleep. Then you can’t think carefully and your homework will be wrong. You will not be wise and you may not become wealthy!
Some people go to bed late at night and get up late in the morning. This is not good for them. We should sleep at night when it is dark. The dark helps us sleep well. When the daylight comes, we should get up. This is the time for exercise. If the body is not used, it will become weak. Exercise keeps it strong.
Exercise helps the blood (血液) to move around inside the body. Blood takes nutrition (营养) to all parts of our bodies. The brains (大脑) in our heads also need blood. We think with our brains. If we keep our bodies healthy, and take exercise, we can think better!
Our bodies also need air to breathe (呼吸). Without air we will die. Get up early in the morning and we can have plenty of clean, fresh air. That will keep us healthy and happy.

Japanese farmers often use seaweed as fertilizer. It makes their plants grow better. Many farmers also find seaweed makes a fine food for their animals.
From seaweed the Japanese also get iodine(碘), which they sell to other countries. Iodine is used in many ways all over the world. It is used in making medicine. It is added to the salt we use at the table. Scientists even use one form of iodine to “seed clouds” when they want rain to fall.

I’m happy as a clam(蛤).
Think of a clam. It doesn’t have to do anything. It just sits on a beach or on the bottom of the ocean all day doing nothing. It never has to work. That sounds like happiness, doesn’t it? If someone asks, “How are you today?” you can answer “I am happy as a clam” to let him or her know what a great mood you are in.
I wouldn’t touch that (or him/her) with a ten-foot pole.
Maybe there is a person who you don’t want to be friends with or even talk to. Well, this saying means that you dislike him or her so much that you don’t want to touch or go near him or her, even within ten feet!
You don’t have a leg to stand on.
This saying doesn’t mean that the person you’re talking to has no legs. It means that his or her argument is incorrect. He or she doesn’t have a leg to stand on because he or she has no facts to support what he or she is saying. This saying is a good way to tell people that you think they’re wrong.
Break a leg!
This saying actually means the opposite of what it sounds like. If you tell this to a person, you’re wishing him or her good luck！The saying comes from a superstition(迷信) that whatever you say aloud, the opposite will come true.

| D．if we say “I am ill” aloud, we will become healthy |
Many Chinese cities now face the same sort of problem with air pollution that London faced 40 or 50 years ago．However, this problem is more difficult for Chinese cities to solve．One reason is that more of the pollution comes from the factories, rather than from coal burnt in people’s houses．If these factories were closed, this would harm the economy and lots of people would lose their jobs．Another reason is that changing from coal to cleaner fuel(燃料), like gas, is quite expensive．
However, the air in many Chinese cities is becoming cleaner and cleaner, as the government and people pay more and more attention to cutting down pollution．As a result, there are fewer “pea-soupers”in Beijing than there used to be．
