题目内容

     Habits, whether good or bad, are gradually formed. When a person does a certain thing again, he is driven by some unseen force to do the same thing repeatedly, then a habit is formed. Once a habit is formed, it is difficult, and sometimes impossible, to get rid of. It is therefore very important that we should pay great attention to the formation of habits. Children often form bad habits, some of which remain with them as long as they live. Older persons also form bad habits lasting as long as they live, and sometimes become ruined by them.

　　There are other habits which, when formed in early life, are of great help. Many successful men say that much of their success has something to do with certain habits in early life, such as early rising, honesty and so on.

　　Among the habits which children should not form are laziness, lying, stealing and so on. These are all easily formed habits. Unfortunately older persons often form habits which could have been avoided(避免).

　　We should keep away from(远离) all these bad habits, and try to form such habits as will be good for ourselves and others.

What do you hear? Sounds all around you! You can hear the sound of traffic, the wind in the trees, a dog barking, your own breathing and lots of other things.

But what is sound? Sound happens when something vibrates(振动)or shakes. We can make something vibrate by hitting it. Try this experiment. Put your ruler on your desk so that part of it sticks out(伸出)over the edge . Put your hand on the part of the ruler that is on the desk. Now pull the part that is sticking out over the edge down, and then let it go. The part you let go will vibrate. It will move up and down very quickly, and give out sound.

The part of the ruler sticking out over the edge of the desk produced the sound. If you make that part longer, you will hear a lower sound. When you shorten it, you will hear a higher sound. Why does this happen?

When you shorten the ruler, it will vibrate more quickly. When something vibrates more quickly it produces a higher sound. If you lengthen the ruler, it will vibrate more slowly. When something vibrates more slowly, it produces a lower sound.

A. When something vibrates.                          B. When something shakes.
