課本應該被循環再用嗎？Textbooks Should Be Recycled?

　　Now, many primary schools and middle schools are recycling textbooks. In my opinion, its necessary.

　　現在,許多小學和中學都回收課本。在我看來，這是有必要的。

　　As you know, save paper means save trees and money. Trees also have many advantages, like: to produce oxygen, control the climate. Some trees can produce rubber or medicine etc. Trees are a kind of natural resources. We must protect them.

　　如你所知，節省紙張意味著節約樹木和金錢。樹木也有很多優點，比如:生產氧氣，控制氣候。一些樹可以生產橡膠或醫學用途等。樹是一種自然資源。我們必須保護他們。

　　To print books, we must use a lot of time and people. We have to use electricity and water. In China water is rare. So we must save it! Save water is everybodys responsibility.
