    Why Are Trees Important樹為什么重要

    Trees are very important to us. Do you know why？ Let me tell you.樹對于我們非常重要，你知道為什么嗎？讓我來告訴你吧。

    Trees take in carbon dioxide from the air and make oxygen. That's important. People and animals need oxygen to live. Many small animals and inserts live in the trees. Some of them also get food from trees. Trees can also stop water and soil from going away. If we have a lot of trees， we stop deserts from being large. I think this is very important. You know， trees are green. They can make our country even more beautuful.樹木可以吸收二氧化碳，并釋放氧氣，這非常重要。人類和動物需要依靠氧氣生存。很多小動物和昆蟲居住在樹里，有些從樹里獲取食物。樹木還可以防止水土流失。如果我們有很多樹就可以阻止沙漠擴大。我認為這非常重要。眾所周知，樹是綠色的，它們能使我們的國家更加美麗。

    Trees are our good friends. We should plant more trees and take good care of them.樹是我們的好朋友。我們應該種更多的樹，并好好照料它們。
