九年级英语单选题困难题查看答案及解析

When we can see well, we do not think about our eyes often. It is only when we can not see perfectly that we come to see how important our eyes are.

People who are nearsighted can only see things that are very close to their eyes. Many people who do a lot of close work, such as writing and reading, become nearsighted. Then they have to wear glasses in order to see distant things clearly.

People who are farsighted face just the opposite problem. They can see things that are far away, but they have difficulty 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. This, too, can be corrected by glasses. Some people’s eyes become cloudy because of cataracts. Long ago these people often became blind. Now, however, it is possible to operate on the cataracts and remove them.

When night falls, colors become fainter to the eyes and finally disappear. After your eyes have grown used to the dark, you can see better if you use the side of your eyes rather than the centers. Sometimes, after dark, you see a small thing to one side of you, which seems to disappear if you turn your head in its direction. This is because when you turn your head, you are looking at the thing too directly. Men on guard duty sometimes think they see something moving to one side of them. When they turn to look straight at it, they can not see it any more, and they believe they were mistaken. However, this mistake happens because the center of the eye, which is very sensitive in daylight, is not as sensitive as the sides of the eye after dark.

1.We don’t know that our eyes are of great importance until ________.

A. we think about our eyes

B. we cannot see clearly

C. we wear glasses

D. we have to do much reading

2.According to the passage, a ________ is more likely to be nearsighted.

A. tailor　　 B. doctor　　 C. guard　　 D. painter

3.People who are farsighted ________ .

A. cannot do a lot of close work without glasses

B. can only see things that are very close to their eyes

C. have difficulty reading a book if they hold it at arm’s length

D. have the same problem as the nearsighted people

4.To see a small thing at night, it is better to look ________ .

A. with wide open eyes

B. with half shut or narrowed eyes

C. straight at it

D. in a slightly different direction

When we can see well, we do not think about our eyes often: It is only when we cannot see perfectly that we come to see how important our eyes are.

People who are nearsighted（近视的） can only see things that are very close to their eyes. Many people who do a lot of close work, such as writing and reading, become nearsighted. Then they have to wear glasses in order to see distant things clearly.

People who are farsighted face just the opposite problem. They can see things that are far away, but they have difficulty reading a book if they don't 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. 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.

When night falls, colors become fainter（更模糊） to the eyes and finally disappear. After your eyes have grown used to the dark, you can see better if you use the side of your eyes rather than the centers. Sometimes, after dark, you see a small thing to one side of you. It seems to disappear if you turn your head in its direction. This is because when you turn your head, you are looking at the thing too directly. Men on guard duty sometimes think they see something moving to one side of them. When they turn to look straight at it, they cannot see it anymore, and they believe they were mistaken. However, this mistake happens because the center of the eye, which is very sensitive (敏感的) in daylight, is not as sensitive as the sides of the eye after dark,

九年级英语单选题中等难度题查看答案及解析

We don’t know how different our future will be in the future. We can only try to imagine it.

At first we think about human relationship. In the year 2050, we will use computers almost every day we will be making new friends through the Internet—even our husbands or wives will be met in this way. It will be much faster and easier for us. On the other hand, our relationships with people won’t be as important as they are today—we will feel a little lonely.

Computers will also help us in many other activities in 2050. For example, they will be used by the children at school to make their learning easier. In addition, there will be much more other machines which will play a similar role as computers, like robots which will do the homework for us.

Spending holidays will also be completely different. Traveling to other planets or to the moon will be available for everyone. Means(方式) of transport will, of course, change, too. We will be using solar-powered cars, which will be much cleaner.

We could expect that the faster technological progress would lead to a more polluted environment. But it isn’t true. We will pay more attention to protecting the environment. And, scientists will probably find cures for many dangerous diseases, like cancer or AIDS. Therefore, our surroundings as well as health will be in better condition.

Although we can’t predict(预测) the exact changes which will be made in the world, we often think about them. We worry about our and our children’s future; we have expectations, hopes as well as fears. But I think we should be rather sanguine(乐观的) about our future. We should be happy and believe good things will happen.

1.Why will people probably feel a little lonely in 2050?

A. Because the number of people will become much smaller．

B. Because there will be less face-to-face communication

C. Because people won’t like making friends with each other

D. Because people won’t communicate with each other much often．

2.According to the passage, which of the following will happen in 2050?

A. The relationship between people will be more important than today.

B. The way of spending holidays will be the same as that of today.

C. It won’t be difficult for people to travel to other planets.

D. Our environment will be much more polluted with a growing number of cars.

3. What does the passage mainly talk about?

A. How people will communicate in the year 2050.

B. What our life will be like in the year 2050.

C. How people will travel and spend their holidays in the year 2050.

D. What high technology will appear in the year 2050.
