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

1 . Reduce

If you want to reduce waste you should use things wisely (明智地）. A large number of trees are being cut down to make paper. If everyone uses a little paper carelessly and throws 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 away. Give your clothes you do not use or the ones which are too small to the poor. In a family you may pass on such clothes to younger brothers or sisters.

3. Recycle

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

4. Recover

When you buy a box of apples there may be a few rotten(腐烂的）apples and you have two choices： one is to throw the whole apples 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. 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 repairing. It is true that North America is a “ throw — away ” society but the time to change our way of life has come so that we can protect our environment. Every one of us should try our best.
