Save Our Earth
We all live in the earth. The earth is our home. We have only one earth. We must take care of it. It gives us the best environment. If we harm it, it will be angry. And then we will have a terrible end. There are three problems in our earth, they are pollution, disaster and illness.

解析：试题分析：本题要求写一篇保护环境的议论文。要求中已经给出了主要要点，因此要求我们自由发挥的地方较多，只是需要注意不能遗留要求中的要点。动笔前先要注意认真审题，分析体裁，确定时态；分析内容要点，列出一些基本词汇及词组；注意表达的条理性，用好连接词；为丰富文章的文采，可以多用一些复合句。最后，注意不要犯语法、句法以及搭配性错误，写好后反复读几遍，适当修改。
