The world is divided into    1    parts. One half of the world is rich and the other is poor. In the poor part, a lot of people have   2   got enough to eat. When they are ill,   3   of the hospital can receive them because they have   4   money. In the rich part, a lot of people eat too much. For example, a dog    5    a cat in North America eats    6   than a child in the poor countries.

The poor countries have some difficult problems. Sometimes the land is too poor to grow   7    on. People there have   8   rich land   9   enough water. The land can be made better, but a lot of things must be done. The people   10   be taught and water must be found.

But rich countries have problem, too. There are not always good places to  11  . Sometimes the air is not clean and the rivers are   12   dirty to swim in or drink. The roads and streets are full of people and buses. Cars and buses have to move    13  . Noise is too much. Some people don’t have houses. Something must be done about these problems. The air and the rivers must be cleaned and be   14   clean. More houses have to be built.   15   these can’t be done easily.

Did you know that each day one person in the US throws away 4.4 pounds of rubbish? Almost every month, we throw away our own rubbish in packaging alone. Packaging ( including boxes, bags, etc) comes to our homes with the things we have bought. Several weeks ago, the TV news said that in a city in Italy tons of rubbish were piled up in the streets, and the smell was rather terrible. What can we do to help? We should get to know the following Rs.

    Reduce  To reduce means to make less rubbish. That is one of the first things we all should do for the environment. Reduce your rubbish by doing things like packing your lunch in reusable containers(可在利用的容器), taking smaller potions(份) at dinner so you don’t waste food when you have had enough, writing on both sides of paper, and using less water when taking a shower.

   Reuse   To reuse is to use things again. Think about the bags you get from the store. They can be reused to carry your lunch, to hold your rubbish, or to collect used cans. You can even take them back to the store the next time to carry your things instead of getting a new bag!

Recycle (回收利用)  Recycling is an important part of keeping our planet clean and green. It can also save energy. Be sure that you don’t throw things in the rubbish that can be recycled to make something else. Paper, plastic, cans and bottles can all be recycled, but food, electrical waste and mobile phones can’t. When you are not sure whether something can be recycled, go to your parents and teachers for advice.

   Follow the three Rs, and every one of us can do something to save the earth. It is also the best way to save ourselves.
