How much sleep do we need? We are all different. Some people need only three hours of sleep a night. Others need ten hours of sleep a night. Most Americans sleep an average (平均) of seven to eight hours a night. After the age of fifty, the average sleeping time goes down to 6.5 hours a night.
Most people have a bad night when they can’t fall asleep (入睡). The name of this problem is called insomnia.
This isn’t a new problem. Many famous people in history had insomnia, too. Some of these people had special ideas to make them sleep. Benjamin Franklin, the famous inventor, had four beds. He moved(移动) from one to another to fall asleep. King Louis XI V (国王路易十四) of France had four hundred and thirteen beds and hoped to fall asleep in one of them. Mark Twain, the famous American writer, had a different way. He lay on his side across the end of his bed.

解析
试题分析：本文讲述我们需要多少时间的睡眠，很多人会患有失眠症很多名人也不例外。
小题1:C细节理解题。根据第一段提到After the age of fifty, the average sleeping time goes down to 6.5 hours a night.可知50之后每晚睡6.5个小时。故选C项。
小题2:B 细节理解题。根据第三段中提到King Louis XI V (国王路易十四) of France had four hundred and thirteen beds and hoped to fall asleep in one of them他是法国人可得知A错误。根据第三段提到Many famous people in history had insomnia, too.许多名人也会失眠故B项正确。Benjamin Franklin, the famous inventor, had four beds. He moved(移动) from one to another to fall asleep.他是个著名的发明家，而不是作家，故C项错误。根据第一段提到Benjamin Franklin, the famous inventor, had four beds. He moved(移动) from one to another to fall asleep.50岁以后才会睡眠6.5小时故D项错误。
小题3:A 细节推断题。根据最后一段提到King Louis XI V (国王路易十四) of France had four hundred and thirteen beds and hoped to fall asleep in one of them他有四百三十多张床，希望能在某张床上快速睡着。.故选A项。
小题4:C 猜测词意。根据第二段Most people have a bad night when they can’t fall asleep (入睡). The name of this problem is called insomnia 许多人晚上不睡不着，这个问题的名字叫失眠，故选C项。
小题5:B 段落大意。第一段首先通过发问的形式提到我们需要多少的睡眠，这是不同的，有的人长有的人短，美国人平均7个小时，而等待50岁后是6.5个小时，可知在讲我们需要多少时间睡眠。故B项符合题意。

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.
根据短文内容，选择正确答案。

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．
