教师可结合第71课练习册中的练习2，适当给出一些书面练习，让学生在课后进行操练。
写作建议
教师可以让学生写两封短信一封是介绍自己的病情，一封是回信告诉对方如何保持健康。可以使用下列词语（do more exercise, play ball game, eat less sweets, have good rest, have a cold, have a fever, have a headache, need a good rest ）
学生完成练习后，再读课文，并回答课后问题。
学法指导
1．本单元新出现的词汇比较多，集中记忆比较困难，可以采用分散记忆法。把单词放在课文中去记忆，这样就会减少难度。
2．两篇课文篇幅都比较长，对课文内容能熟读就行了。但对一些常用的短语必须要牢牢掌握。如：be tired, wake up, be good for sb. , as soon as, fall asleep, be busy doing sth., all night long, a terrible storm, stop the ship from going down, sleeping pills, listen to music, be fast asleep, hard work, play the same piece, feel weak and died, rest every five minutes, look over, nothing much wrong with sb. ,What do you mean? rich food, take enough exercise, eat less food, some dry bread, feel much healthier, instead of等等。
3．本单元的语法项目①情态动词have to与②系动词。要掌握他们的用法必须在了解他们基本含义的基础上，通过一定量的口头和书面练习。
词汇辨析
1. too much / much too
too much意为“太多”，常修饰不可数名词或行为动词；而much too意为“太”，常修饰形容词或副词，以加强语气。如：
He always eats too much meat, so he is much too fat. 他总是吃太多的肉，因此他太胖了。
You talked too much at the meeting. 你在会上讲得太多了。
另外，too much也可以单独用，相当于一个名词或代词。如：
He is a kind man and often gives too much but gets too little. 他是个好心人，经常付出的多而得到的回报少。
2. instead / instead of
instead与instead of都有“代替”之意，instead 后不跟其它成分，通常置于句末作状语；而instead of后常跟名词、代词、v-ing形式或介词短语等。如：
Why don’t you come and play volleyball instead? 你们为什么不来改打排球呢？
We can use the USA instead of America. 我们可以用the USA来代替America.
He went to school on foot instead of by bike yesterday. 昨天他步行去上学，没有骑自行车。
Jim likes swimming instead of skating. 吉姆喜欢游泳，而不是滑冰。
