2008年已经悄然到来。新年新气象。今天我们特意请来了一位新朋友——R。他说他的“环保五部曲”可以给我们的环境带来一个崭新的面貌。咱们来看一看吧！

“R”教我学环保——reduce（I）

Hello, boys and girls!I’m your new friend“R”. Everyone knows that it’s very important to protect our environment. How can we do about it? Here are some rules for us. Today let me tell you the first rule.

To protect our environment, the best way is to reduce (减少) the waste. That’s to say, we should use things wisely  (聪明地).

For example, we can use two sides of the paper. Before you leave the room, remember to turn off the light. After we use water, don’t forget to cut off the tap, and so on.

In fact, all kinds of resources (资源) are limited (有限的), so it is necessary to reduce the waste. If not, we will have nothing left one day.

Question:

What does the “reduce” rule mainly require （要求） us to do?

To            things          .
