Unit 18 Seeing the doctor,
老师可以布置学生参考练习册第69课练习3，以学生自己的名义给班主任老师或英语老师写张请假条。
有关“看病就医”话题的教学
本单元的主要交际项目是看病，所有教学活动都应围绕这一主题展开。建议教师设计多种情景，使学生在做中学，在实践中掌握。
（1）设置看病的情景进行表演
情景：Lin Lin was ill, she called her teacher to ask for a leave.
对话：
Mr. Li: Hello.
Lin Lin: Hello, it is Lin Lin here. Is that Mr. Li?
Mr. Li: Yes, what’s the matter with you?
Lin Lin: I have a cold and a terrible headache.
Mr. Li: Did you take any medicine?
Lin Lin: Yes, my mother took me to the hospital last night. The doctor said it is not serious. But he thought I had better have a two-day’s rest.
Mr. Li: Well, that doesn’t matter. I hope you’ll feel better soon.
Lin Lin: Thank you very much.
此对话可在课堂上组织学生进行表演。
Name: Age: Sex:
Symptom（症状）:
Reason:（原因）
Advice: （建议）
（2）学生可以根据此表的格式写一张医生诊断证明
（3）教师可以组织学生建立一个临时诊所，一个学生准备一个听疹器，一顶白帽子和一张桌子，扮演成医生，其他几个同学办成不同症状的病人，进行对话表演。
阅读训练教学
本单元安排了两篇极富幽默感的阅读文章，单词较多。建议教师重点训练学生猜词，判断大意的能力。教师可在阅读文章之前，设计部分重点词汇练习，让学生猜出括号中单词大意。如下：
1.Every morning My mother always（wakes me up）and I have to get up on time.
2.The students are tired and（as soon as）school is over, they go home at once.
3. I have worked for a day, I am very（tired）and I don’t want to do it any more.
4.My father always takes （morning exercises）every morning. So he can keep good health.
第70课讲述的是一个叫Roy的男孩由于老做梦而去看医生的故事。做梦是每个人都经历过的事情，特别是10多岁的孩子，正处于多梦时期。课文从讨论做梦入手，容易引起学生的兴趣，而像Roy那样梦中总是于累人活儿的学生也有不少。
在阅读开始之前，老师可以提几个简单的问题，如：Do you often dream？What do you usually do when you dream? /Would you like to know something about Roy’s dream?学生对阅读的兴趣，增强他们急于了解课文内容的迫切心情。同时为了减少学生阅读的难度，可以先列出一些估计学生比较难于理解的词汇、短语或句子。如：as soon as, be busy doing sth., terrible storm, stop the ship from going down .sleeping pills, be awake, fall asleep, relax, Don't they work? light music等。阅读完以后让学生做练习册中第70课的练习一，看看他们是否已经理解了课文的内容。
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. . . .

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 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：
