　　It isn't strictly true that one half of the world is rich and the other half is poor. It is one-third that is very rich and two-thirds that are very poor.

　　People in the rich countries don't understand the great difference between them and those in the poorer countries. A very simple example is that a dog or a cat in north America eats better than a child in the poorer countries. A fisherman in South America may be catching fish which is processed into pet food, and his own children are not getting enough to eat for their bodies to grow properly.

　　Although a lot of the world's natural resources like oil come from these poorer countries, people in the richer countries are using about sixty times as much of these resources as people in Asia or Africa. And it's the richer countries that decide what kind of prices they are ready to pay for these resources. And the prices the richer countries get for their own exports, however, are always rising. So they are getting richer and richer and the poorer countries are getting poorer.

1．________ of the world is very rich and ________ very poor.

[　　]

A．One half, the other half is

B．One-third, two-thirds are

3．A lot of the world's natural resources come from ________.

Water is the most important in our lives. Not Many people understand this but it’s quite true. The human body can go without food for a long time. We’ve got many examples for this. Yet two or three dayswithout water can usually make people die. Man can’t live without water.
Many people don’t understand how much water the human body needs to work well, and many people, especially young people, do not drink enough water, even in very hot weather. About two thirds of our body is water. When we do sports, some of the water will get away from our body. If we don’t drink some water, our body won’t have enough water. And if we don’t have enough water, we’ll feel tired and many of us will get ill. So you know how important water is to us.
But at present we face water crisis(危机). Water is becoming less and less. So， we should protect water resources(资源) and try our best to save water in our daily life. Here are some tips for saving water:
1. Turn off the tap(水龙头) in lime.
2. Take shorter showers.
3. Don’t let water run while washing your face and reuse the water after we finish washing.
4. Encourage your friends and neighbors to join in the action of saving water.
【小题1】 Nobody can live without water.
【小题2】 About one third of our body is water
【小题3】 If one doesn't have enough water, he’ll feel tired and may get ill.
【小题4】 We’d better take longer showers and let water run while washing.
【小题5】 It’s our duty to protect water resources and save water.

In Britain, some people say they will do anything if a famous person they love asks them to. One in three people in Britain have a new kind of disease(病)—they love a famous person too much.

Some people love famous stars like Britney Spears, David Beckham or even Tony Blair. It is not just the young, grown-ups have the same problem. One in four people are so interested in their heroes that it affects their life.

There are two ways of worshipping(崇拜) famous people. One way is just to follow them or talk about them with friends for fun. The other is a more serious way. People have very strong feelings for them and think they are their friends. People who do so for fun are found to be happier. But those who have strong feelings for a famous person are perhaps to feel more lonely and worried.

“Worshipping famous people is not certainly a bad thing,” Dr.John, an expert said, “But like many things, overdoing it may not always be good for you.”

Children can spend hours a day looking at computer screens and other digital devices(数码设备). Some eye doctors say this leads to an increase in “computer vision syndrome(电脑视力综合症).”

Nathan Bonilla-Warford is an optometrist（验光师）in Tampa, Florida. He has seen an increase in problems in children. “A lot more children come into the office either because their parents have noticed that they have headaches or red or watery eyes or discomfort, or because their nearsightedness appears to be increasing and they’re worried,” he says.

Dr. Bonilla-Warford says part of the problem is that children may be more likely to pay no attention to early warning signs than adults. “Even if their eyes start to feel uncomfortable or they start to get a headache, they’re less likely to tell their parents, because they don’t want to have the game or the computer or whatever taken away,” he explains.

He says another part of the problem is that people blink（眨眼）less often when they use digital devices. He says, “A person who uses an electronic device blinks about one third as much as we normally do in everyday life. And so that can result in the front part of the eye drying and not staying protected like normal.”

Eye doctors offer suggestions like following which is known as the 20/20/20 rule. That means every twenty minutes look away twenty feet or more for at least twenty seconds from whatever device you’re using.

Other suggestions include putting more distance between you and the device and using good lighting. Of course, another way is to spend less time looking at screens. Many experts say children should spend no more than two hours a day using digital devices—with no screen time for children under two.

But not all eye doctors have noticed an increase in problems in children. Dr. David Hunter, from Children’s Hospital Boston, has not seen an increase in his practice. “While it is possible to develop fatigue looking at screens for a long period of time, there’s certainly no proof that it actually causes any damage（伤害）to the eyes.” he says.

1.Which of the following is true according to the passage?

A．Dr. Bonilla-Warford thinks using computers causes nearsightedness.

B．People keep their eyes protected against drying by blinking normally.

C．Children under two can watch TV for less than two hours a day.

D．Dr. David Hunter says headache causes an increase in eye problems.

2.What does the underlined word “fatigue” mean?

A．Interest.

B．Ability.

C．Tiredness.

D．Difficulty.

3.What can be the best title for the passage?

A．Looking at Screen: Two Hours or More

B．How Can Children Use Their Eyes Properly

C．Using Digital Devices: Advantages and Disadvantages

D．How Much Screen Time Is Too Much for Children
