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.

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,

Making friend is a skill. Like most skills, it improves with practice. If you want to meet people and make friends, you must be willing（乐意） to take some action. You must first go where there are people. You won’t make friends staying home alone.

Join a club or group, talking with those who like the same things you do is much easier. Or join someone in some activity.

Many people are nervous when talking to new people. After all, meeting strangers means facing the unknown. And it’s human nature to feel a bit uncomfortable about the unknown.

Most of our fears about dealing with new people come from doubts about ourselves. We imagine other people are giving an opinion about us-finding us too tall or too short, too this or too that. But don’t forget that they must be feeling the same away. Try to accept(接受)yourself as you are, and try to put the other person at ease(不拘束). You’ll both feel more comfortable.

Try to keep self-confident(自信)even when you don’t feel that way when you enter a room full of strangers, such as a new classroom, walk tall(趾高气扬)and straight, look directly at other people and smile.

If you see someone you’d like to speak to, say something. Don’t wait for the other person to start a conversation.

Just meeting someone new does not mean that you will make friends with that person-friendship is based on each other’s liking and “give and take”. They take time and efforts to develop. And there are things that keep a new friendship from growing.
