Unit 18 Seeing the doctor,
第72课的阅读短文讲的是一个胖女士请医生看病的故事。在组织学生阅读前老师首先问学生第一个问题：Is the woman fat or thin？然后问第二个问题：Why did the woman go to see the doctor？让学生围绕这些问题去阅读。等学生阅读完以后，老师可以用一些最简单的一般问句问学生，例如：Is the woman feeling very well？／Did the woman have to sit down and rest every five minutes when she worked yesterday？等。然后让学生听录音，加深印象。最后，教师可以让学生做课文改写以后的填空练习。这样能使阅读、听力、书面训练有机地结合在一起，使教学效果更趋于完美。
语法教学
1．情态动词have to
（l）情态动词have to和must在意义上基本相同，在很多情况下二者可以互换使用。但must是强调说话人的主观看法，而have to强调的是客观需要。从形式上看must适用于所有的人称，没有时态的变化；而have to有第三人称单数has to，还有时态的变化：had to（过去时），will have to（一般现在将来时）等。例如：
①There must be some students in the classroom now.
②We must learn English well.
③He must stay at home and look after his brother.
④There is no bus, we have to go to school on foot.
⑤Lucy’s mother is ill in hospital, she has to look after her.
⑥She couldn’t find her pen, she had to buy a new one.
⑦The students will have to know how to use the computers．
（2）含有情态动词have to的各种句型
①陈述句
I/We/You/They have to/had to. . . .
take this medicine three times a day
clean the classroom once a day
②主语是第三人称单数
She/He has to/had to. . . .
take more exercise
drink more water
③疑问句（借助助动词do/does/did／will等）
Do I have to. . .? Yes, you do./No,you don't.
Does she/he have to. . . ? Yes, she/he does. /No. she/he doesn t.
Did she/he have to. . .? Yes, she/he did./No, she/he didn't.
④特殊疑问句
What do they have to do now?
What does he/she have to say at the meeting?
Why did he/she have to see a doctor?
Which book do we have to read?
教师可通过两人一组的形式操练有关内容，最后叫几个小组到教室前面表演。
2．系动词
系动词本身有一定的词义，但不能独立作谓语，必须和后面的由名词（短语）、形容词（短语）副词或介词短语构成的表语一起使用。最常用的系动词是be，另外还有look，become，get，seem，turn，grow，take，feel，soled，small筹。如：
(1) Twins usually look the same.
(2) The teacher became angry.
(3) His uncle is an English teacher.
(4) They look very happy/sad.
(5) This kind of apple tastes sweet.
(6) After he left school, he became a doctor.
(7) This food smells good.
(8) His face goes red.
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。
疑难解析
1. What’s the trouble？你怎么了？
这是口语中常用的句子，常用于询问对方身体哪里不舒服或发生了什么不幸的事。类似的句子还有：What’s the matter (with you)? 或What’s wrong (with you)?
trouble名词，意思是“烦恼，苦恼，忧虑，困难”。常见的搭配有：go to the trouble“不辞辛劳地做某事”；get into trouble“陷入困境，惹麻烦”；be in trouble“处于不幸／苦恼／困境之中”。例如：
My teacher went to the trouble of teaching us.我的老师不辞劳苦地教我们。
They got into trouble when they climbed that hill yesterday.昨天他们爬山时陷入了困境。
He is always ready to help others when they are in trouble.当他们处于困境时，他总是乐于帮助他们。
2. I had to sit down and rest every five minutes． 每五分钟我就得坐下来休息一会儿。
every形容词，意思是“每个”，同数词连用时，名词可以有复数形式。表示“每……，每隔……的”。例如：
He comes every three days. 他每隔两天来一次。（他每三天来一次。）
She goes to Beijing every other year. 她隔年去一趟北京。
3. Last night, as soon as I fell asleep I dreamt that I went to the garden.昨天夜里我一睡着就梦见我到花园里去了。
1）as soon as是连词，引导时间状语从句，表示“一……就……”。如：
It began to snow as soon as I got home. 我一到家里就开始下雪了。
He will call you as soon as he arrives. 他一到就会给你电话的。
2）fall asleep 意思是“入睡的，睡着的”，fall在此是连系动词，后常跟asleep或ill作表语。如：
He was too tired, so he fell asleep very soon. 他太累了，因此很快就睡着了。
类似的词还有before, after, until, when等。当主句是一般将来时态时，时间状语从句必须用一般现在时态。
3）…that I went to the garden. 这是由that引导的从句作宾语，叫做宾语从句。如：
He said that he could not sleep well. 他说他睡不好。
4. They taste delicious. 它们吃起来很香。
taste是系动词。常用的系动词有：be, look, seem, feel, smell, sound, get, become等，系动词后常用名词、形容词、副词和介词短语作表语。例如：
(1) The teacher seems angry. 老师似乎生气了。
