Dearsirs,
I am Li Hua, a student from Xin Hua Middle School. I often visit your website. I am very glad to know that you will make a new round of courses and are collecting topics facing the middle school students. As a student, I really want to recommend a topic to you wholeheartedly. It is that we should be thankful. Living in this world, we have many people that we should be thankful to. We should be thankful to our parents because it was they that brought us into this world; we should be thankful to our teachers because they taught us everything we know and we should be thankful to our friends because when we meet difficulties, they always give us a hand. So I can say we live in a grateful world. I hope that the activity will be a great success.
Yours
Li Hua

这是一篇命题巧妙地书写体半开发性提纲式作文。话题树有教育意义，符合中学实际引导学生思考问题。在写作中应注意如下几点：
1. 紧紧围绕话题“我们应该感恩”。
2. 但自我简介、写信目录、推荐的理由、预祝活动成功都是围绕话题展开。
3. 注意分清段落层次，上下文的过渡。
