Health is very important for us. But how can we keep healthy? I think we should do three things.
First, we should eat healthy food. For example, we should eat more fruits and vegetables every day. They give us vitamins. We should eat less junk food, like hamburgers and chips. Drinking enough water is also important.
Second, we need to do more exercise. We can run, swim, or play ball games. Exercise makes our bodies strong. I often play basketball with my classmates after school. It is fun and good for my health.
Third, we must have enough sleep. It is important to go to bed early and get up early. We need about nine hours of sleep every night. It helps us have enough energy for the next day’s study.
If we do these things, we can be healthy and happy.
介绍： 这篇文章的题材是“说明方法或建议”，属于说明文，是考试中另一种常见且重要的文体，能体现学生的逻辑思维能力。本文结构极其清晰，采用了“总-分-总”的经典说明文结构。开头开门见山，提出“健康很重要”以及“我们应该做什么”的中心问题。主体部分使用了“First”, “Second”, “Third”三个逻辑词，条理分明地从饮食、锻炼和睡眠三个方面给出了具体建议，每一条建议都配有简单的举例说明（“For example…”, “like hamburgers and chips”, “run, swim, or play ball games”），让建议内容具体化，易于理解。语言上，大量使用了情态动词“should”和“can”，以及祈使句的表达方式，这是提出建议类文章的典型特征，用法规范。结尾部分（“If we do these things, we can be healthy and happy.”）总结全文，重申了观点，干净利落。这篇范文对于如何写好一篇条理清晰的说明文给出了极佳的示范，学生可以轻松模仿其框架来应对“如何做某事”的同类话题。
