However,people in China began to use paper money in the 10th century. 34     was invented by a Chinese about 2 000 years ago. His name was Cai Lun. He then  35 these pieces of paper together and made them into a 36 .

Now paper mainly comes from trees. We use it every day. 37 we waste a lot of it. If we keep on doing so, people 38 cut down many more trees. Then there will not be any trees left. If there are no 39 , there will be no paper.

So how can we 40 paper? When we mak­ing notes,we can use 41 sides of each piece of paper. We  can  buy  drinks  in bottles instead of 42  in paper packets. We can also use cotton handkerchiefs ( ??????) and not the paper ones.

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.

     We humans are only born with one set of eyes, so it's our job to take care of them for our whole lives. The good news is that if we do a few simple things every day, we can maintain (保持) our eyesight and reduce (减少) the risk of ever hurting our eyes.

     Almost all doctors agree that we can improve and maintain good eyesight by eating lots of fresh fruits and vegetables. It is especially important for us to eat vegetables like carrots and sweet potatoes.  Besides, we need to protect our eyes when we spend a long time in bright sunlight. The best way to do. this is by wearing sunglasses that have 100% UV (紫外线)  protection. What's more, it is necessary to protect our eyes when we work with dangerous chemicals (化学物质).  For this reason we should always wear goggles in chemistry labs at work or at school. Finally, we should not spend too much time in front of the computer or television screen. That is why doctors advise if we have to use a computer for a long time, we should take a short break every fifteen or thirty minutes.

     Maintaining good eyesight is important. If we do these few simple things we can protect our eyes and reduce the chances of losing our eyes.
