You cannot see any object unless light from that object gets into your eyes. Some of the things you see give off light of their own. The sun, the stars, a lighted lamp are examples that can be ssen by their own light. Such things are luminous. Most of the things you see are not giving off light of their own. They are simply reflecting light that falls on them from the sun or some other luminous bodies. Then moon , for example , does not give off any light of its own. It is non-luminous. You see it because sunlight falls on it and some of it reflects in your direction. So moonlight is only secondhand sunlight.

When you look at a book, it sends your eyes some of the light that falls on it, and you see the book. If light could be kept out from where you are so that there would be no light for the book to reflect, then you could not see the book even with your eyes wide open.

Light travels so fast that the time in which it travels from the book you are reading to your eyes is so short as if it took no time at all. Light reaches us form the moon , which is about 380,000 kilometers away, in only a little more than a second.

1.You can see the book because___________.

2.The word “ reflects”  means____________.

3.    ___________ have light of their won.

Strong winds, sand in the air, poor visibility (能见度), we all know the characteristics of a sandstorm. But what else do you know about them?

Did you know, for example, that the first sandstorm of 2009 hit north China’s Inner Mongolia autonomous region late February?

Sandstorms are today a feature of life in northern China because of desertification (沙漠化) and the retreat (退化) of the northern grasslands. They usually occur between February and May.

Fortunately, sandstorms this year should be fewer than in past years in north China, according to the National Meteorological Center (中央气象台).

And the chances of sandstorms hitting Beijing are small, because recent rain has stopped drought and reduced dry dirt and dust. Tree planting, and other measures taken by the government, has also helped decrease the chance of sandstorms in the city.

Sandstorms can be dangerous. However, there are measures you can take to protect yourself from harm.

﹡Wear a mask. Cover your nose and mouth with a mask that can keep out sand, or use a damp handkerchief.

﹡If you are driving and the storm is at a distance, it may be possible to outrun (超过) it. If it looks like you will be caught in the storm, stop and wait it out.

﹡Take a cover. If there is no shelter, then lie down. Keep eyes, nose and mouth covered. Cover your head with your arms or a backpack to protect yourself against flying objects.

If you are caught in a desert sandstorm, take the following actions.

﹡Mark your direction before lying down. It is easy to get lost in a desert.

﹡Keep plenty of water at hand. If you get lost, you need water to survive until you find your way or help arrives.

﹡Stay together if traveling in a group. Lock arms if caught in a sandstorm. The most useful measure would actually be to make sandstorms disappear forever. To make this goal come true, people should plant trees, and stop desertification.

Today, the straight-line distance between Tiananmen Square and a desert called Tianmo in Hebei province is only about 80km. If desertification is not stopped, environmental protection experts say, it will probably not be long before Beijingers can catch a camel to work.

1.According to the passage, which of the following statements is true?

A. So far in 2009 no sandstorm has happened.

B. Sandstorms usually happen in spring.

C. Sandstorms are a feature of life in China.

D. In sandstorms in cities, what you need to protect yourself from is just the sand in the air.

2.Which may not be the right action to take to protect yourself from harm in a sandstorm?

A. Finding a shelter.

B. Covering your head with a bag.

C. Lying down.

D. When driving, speed up and rush through the sandstorm.

3.What can we infer from the passage ?

A. North China has been suffering from sandstorms for several years.

B. The distance between Beijing and the desert has made the chances of sandstorms hitting Beijing small this year.

C. Planting trees can help make sandstorms disappear.

D. It is more dangerous to be caught in sandstorms in cities because there are more flying objects.

4.What’s the best title of the passage?

A. The realities of sandstorm                          B. The cause of sandstorm.

C. The influences of sandstorm                      D. The future of sandstorm.

When we see well, we do not think about our eyes very often. It is only when we cannot see perfectly that we realize how important our eyes are.

People who are near-sighted can only see things that are very close to their eyes. Everything else seems blurry. Many people who do a lot of work, such as writing, reading and sewing become near-sighted. People who are far-sighted suffer from just the opposite problem. They can see things that are far away, but they have difficulty in reading a book unless they hold it at arm’s length. If they want to do much reading, they must get glasses, too.

Other people do not see clearly because their eyes are not exactly the right shape. They have what is called astigmatism (散光). This, too, can be corrected by glasses. Some people’s eyes become cloudy because of cataracts (白内障). Long ago these people often became blind. Now, however, it is possible to operate on the cataracts and remove them.

Having two good eyes is important for judging distances. Each eye sees things from a slightly different angle. To prove this to yourself, look at an object out of one eye; then look at the same object out of your other eye. You will find the object’s relation to the background and other things around it has changed. The difference between these two different eye views helps us to judge how far away an object is. People who have only one eye cannot judge distances as people with two eyes.

1.We should take good care of our eyes________.     .

2.When things far away seem indistinct(模糊不清) , one is probably________.     .

3.The underlined word blurry in the second paragraph probably means_______.

4.Having two eyes instead of one is particularly useful for_______

If you are in a town in a western country, you'll often see people walking with their dogs. It is still true that a dog is the most useful animal in the world. But the reason why one keeps a dog has changed Once upon a time, a man met a dog and wanted it to help him in the fight against other animals, and he found that the dog listened to him and did what he told him to. Later people used dogs for  hunting other animals, and the dogs didn't eat what they got until their master agreed. So dogs were used for driving sheep and guarding chicks. But now the people in the towns and cities do not need dogs to fight other animals. Of course they keep them to frighten thieves, but the most important reason is that people feel lonely in the city. For a child, a dog is his best friend when he has no friends to play with. For a young wife, a dog is her child when she doesn’t have her own. For old people, a dog is also a child when their real children have grown up and left. Now people do not have to use a dog, but they keep it as a friend, just like a member of the family.

Imagine this situation. You pass a group of people. The people are talking to each other. You cannot hear what they are saying. But suddenly they start laughing. What would you think? Would you think they were laughing at something funny that one of them said? Or—be honest with yourself—would you think they were laughing at you? Yes, you.

Being laughed at is a common fear. But a major study published in two thousand and nine found that this fear is not the same around the world. It differs from culture to culture.

People in Finland were the least likely to believe that people laughing in their presence were making fun of them. Less than ten percent of Finns in the study said they would think that, compared to eighty percent of people in Thailand.

Some people in the study said they felt unsure of themselves in social situations but hid their feelings of insecurity. Others said they avoided social situations where they had been laughed at before.

The study found that people in Turkmenistan and Cambodia were more likely to be in the first group. They would hide their feelings of insecurity if they were around other people’s laughter. But people in Iraq, Egypt and Jordan were more likely to try to avoid such situations if they felt they had been laughed at before.

Shy people often avoid situations that would force them into close contact with other people. They worry that something they say or do will make other people laugh at them. But some people worry much more than others. They may have a disorder called gelotophobia. Gelos is a Greek word. It means laughter. Phobia means fear. This fear of laughter can be truly sad for those who live with it. It can affect how they lead their lives.

In the study, a team from the University of Zurich led more than ninety researchers from around the world. They wanted to understand the difference between normal shyness and true gelotophobia. Another purpose of the study was to compare the levels of fear of being laughed at in different cultures. The researchers surveyed more than twenty-two thousand people in forty-two different languages. The findings appeared in the scientific journal Humor.

1.People in Finland don’t believe other people are making fun of them if________.

A. they suddenly start to laugh

B. they keep on laughing

C. they laugh in their presence

D. they stop laughing suddenly

2.What’s FALSE of the study led by a team from the University of Zurich?

A. They wanted to study the difference between normal shyness and true gelotophobia.

B. They wanted to compare the levels of fear of being laughed at in different cultures.

C. They did such a survey in order to prevent people from being laughed at in public.

D. They surveyed more than 22 thousand people coming from different cultures.

3.The passage is likely to occur in________.

A. an advertisement  B. a science magazine

C. a science fiction    D. a storybook

4.According to the passage, people who suffer from gelotophobia________.

A. care more about being laughed at by others

B. shouldn’t hide their feelings of insecurity

C. should avoid having close contact with other people

D. will lead a happy life so long as they care
