It's important to learn about protecting our environment. Here is a 5R rule for us:

1．Reduce

If you want to reduce waste, you should use things wisely. Millions of trees are being cut down to make paper. If everyone uses a little paper carelessly and throw it out, soon we would not have any trees left. Other things are also being wasted, and people don't know what to do with the waste in big cities. So it is necessary to reduce the waste

2．Reuse

You should always think of reusing the usable things before throwing them out. Give your clothes you do not use or the ones which are too small to the poor. With a family, you may pass on such clothes to younger brothers or sisters.

3. Recycle

Bottles, cans and paper can easily be recycled. By doing so, we save lots of time and money. For example, coke cans are sent to a factory, where they are smashed flat（压平）and melted（融化）and the melted things are made for new coke cans.

4．Recover

When you buy a box of apples, there may be a few rotten（腐烂的）apples, You have two choices: one is to throw the whole apple away, or you could cut off the rotten parts and eat the good parts. In this way, you are recovering the eatable parts of food.

5. Repair

If one of the legs of your table is broken, you can repair it instead of throwing it away. If you want to change for better ones, It is better for you to sell the old things or give them to other people who can use them after doing some repair. It is true that North America is a "throw－away" society(社会).But the time has come to change our way of life so that we can protect our environment. Every one of us should try our best.

In the sea there are many islands. In its warm waters there are some little ones. We call them coral(珊瑚) islands.
A coral island is very nice to look at. It looks like a ring of land with trees, grass, and flowers on it. One part of the ring is open to the water. There is a little round lake inside the island.
If you look into this lake, you will see beautiful coral. You may think they are flowers.
If you look at a piece of coral, you will see many little holes in it. In each of these holes a very small sea animal has lived. These sea animals make the coral.
They began to build under the water. Year after year, the coral grew higher and higher. At last it grew out of the water.
Then the sea brought to it small trees and something else. After some years, these things changed into earth. Sometimes the wind brought seeds to this earth. Sometimes birds flew over it and brought seeds to the island. The little seeds grew. In a few years there were plants all over the island. In a few more years there were trees growing there.
So you see, these islands were built little by little. The workers were very small. Don’t they teach us a lesson? Can you think what the lesson is?
