protect the rainforests?热带雨林对我们很重要。他们是地球的肺。因此对我们来说好好保护它们是必需的。首先，我们应该使人们了解保护它们的原因。接着，我们需要叫他们不要无计划的砍树。对我们来说，我们应该做一些有用的事情。例如，当我们吃饭的时间，我们不准使用一次性筷子（chopsticks for only once). 在我们的生活中，我们最好更少的使用纸（paper）并且一定做到不浪费纸。 Rainforests are very important to us.They are the lungs of the earth. So it is necessary for us to protect them very well. First, we should make people know about the reasons of protecting them. Then we need to ask them not to cut down the trees without plans. For us, we should do something useful. For example,when we have meals, we mustn’t use chopsticks for only once. In our life, we'd better use less paper and be sure not to waste it.
