家风及其影响英语作文【三】
Why Are Trees Important?
Trees are very important to us. Do you know why? Let me tell you.
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 insects 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 beautiful.
Trees are our good friends. We should plant more trees and take good care of them.

It's Our Duty To Protect Our Environment
It's our duty to protect our environment. Where we live? The earth. The earth is the only one place we live in. So you know how important the environment is. But now, some people are harming the environment, like cutting down trees, drawing pictures on public walls, littering onto the ground. It's terrible if we still do it. Now, it's time for all the people in the society to protect the environment. It's our duty. It needs each of us to make a contribution to improving the environment. We should make our environment more and more beautiful.
点评：作者多用学过的'词语不但保证了正确，还巩固了所学的知识，并且注意句型的多样化，如长句，短句，疑问句，使用了“if，so, now, but”等词，整篇文章读起来朗朗上口。实际上，写文章就像串珠子，连接词就在于把一个个单词串起来。
