It’s important to learn things about protecting environment. Here’s a 4Rs rule for us.

·Reduce

If you want to reduce waste, you should use things wisely (明智的). A large number of trees are being cut down to make paper. If everyone uses paper carelessly and then throws it away, soon we would not have any trees left. Some other things are also being wasted, and people don’t know what to do with waste in big cities, so it’s necessary to reduce waste.

·Reuse

You should always think of reusing the usable (可用的) things before throwing them away. Give your clothes or things you don’t use to the poor. In a family, you may pass such clothes on to your younger brothers or sisters.

·Recycle

Bottles, cans and paper can easily be recycled. By doing so we save lots of time and money, for example, cola cans are sent to a factory, where they’re smashed flat（压平）and smelted (熔化), and the metal things are made into new cola cans.

·Repair

If one of the legs of your table is broken, you can repair it. If you want to change for better ones, it’s better for you to sell the old ones or give them to other people who can use them after doing some repair.

从方框中选出所给句子的恰当答语。 （一个答案只能使用一次）

You and your parents can stop worrying- Edison, Pasteur, Darwin and many others were far from being "bright boys " when they were under twenty. Some of them, in the eyes of their teachers, were day- dreamers or slow pupils. So, young men or women, if you have the same experience, don' t fed disappointed.

It is always the case that parents prefer giving mere inspiring examples to encourage their children. If you take piano lessons and are not practicing hard, your parents might justly complain and show you the famous picture of little Mozart in his night- shirt, playing the piano at midnight. But the fact is that he didn’t appear to have much talent(才干)for music when he was quite young. It was not until 22 that Mozart suddenly became fired with a great liking(爱好)for music.

In the sciences, there have been thousands of people who showed great interest in certain subjects from their earliest years, and hundreds who had no idea of what they would do in the future. The well-known French chemist Pasteur displeased his parents because Louris did nothing but drew pictures and went fishing. Pasteur was twenty years old before he showed any interest in science. You have the Wright brothers, who showed great talent in engineering when they were quite young. And you have Thomas Edi-son, whose teacher tried to get him out of the class because his brain was often confused. You have the Nobel Prize Physicist Enrico Fermi, who at 17, had read enough mathematics for a doctor's degree. But there is also Charles Darwin, who hated to go to school when he was young. His farther was once so angry and shouted, "You care for nothing but shooting dogs and rat - catching. You will put your parents to shame."

So who knows what might happen in the future? It is, of course, better for the young people to know what they want to do in life . But they needn’t despair if they don ' t . There is still plenty of time and it’s never too later for success.
