试题分析：这是一篇给材料作文。但本文所给材料比较笼统，我们要做的就是用正确的英语把有关表示健康的内容表达出来。动笔前要认真阅读材料，认真想我们课本中所学的有关健康的要点，并适当发挥。根据材料内容可知本文主要是一般现在时态，注意时态语时间状语的搭配及主谓一致问题。写作中适当使用连词，注意上下文联系紧密，符合逻辑关系。
【亮点说明】这篇短文使用了大量的固定句式和短语，为文章增色不少.如: keep a balanced diet保持均衡饮食；too much food and sugar 太多的食物和糖；We had better not smoke .我们最好不要吸烟等。学习中注意总结,牢记一些固定句式及短语,写作时就可以适当引用,使文章的表达更有逻辑性,更富有条理.
