总的来说写的不错的，只有些小地方用词改一下就更贴切了。
1. 例如开头： what should we do to keep healthy? 最好改为“How do we keep healthy？”
2.you should wash your hands before the meal。 可以不改“meals” 。你的用法是对的，这里是特指。
3.We should eat lots of fresh fruit and vegetables。“fruit ”要变为复数，
4.And you and I must drink plenty of boiled water。 “And you and I” 最好还是用你原来的代词“you”，保持与前面代词一致。即：you must drink plenty of boiled water。
5..We should eat lots of fresh fruit and vegetable，and less meat。 最好用“but”，能强调出少吃肉，多吃蔬菜的意思。
6..We mustn’t stay up late。 最好用“shouldn't get up ”。 mustn’t 有中式英语的味道。
7.Becauae it can cause you have a headache。 你这里有两个动词了。所以“Becauae it cause a headache。”就ok了。
8.We had better keep the air fresh。最好是 we'd better keep the favorable environment with fresh air.
应为原文是能感觉出来时按照中文表达方式来描写了，
重新整理后的作文如下。考虑到文章结构，给你增加了点连接词，但基本保留你自己的风格。给你参考下。
