三、教学步骤
Step1 Revision
1.默写一二单元的单词。

2. 师生或生生自由对话。

Step2 Presentation
1.上课前出示一张同学的照片，说We're classmates and good friends.引出本单元的主题Good friends.。

接着口头提问两个或更多的学生Are you classmates? Yes, we are., 然后再指着另一学生问Who's he/she? He's/She's my classmate xxx.He's polite and helpful.最后让学生间运用所复习的知识做口头练习。

2. 做听力题学形容词并复习一般问句以及肯定和否定回答。

Are you a girl? Yes, I am. /No, I'm not.由此引出含有形容词的一般问句，如：Are you sad/happy? Yes, I am./No, I'm not..接着让学生回忆I'm=I am You're=You are He's=He is She's=She is It's=I t is They're=They are We're=We are ,然后将这些词的be 动词提前，构成一般问句的形
式，再加上形容词，就是本单元的Speaking 中所要复习的。

复习形容词后，让学生间做口头练习。

四、知识讲解
1.问某人的年龄是多大，应该这样说：“How old+be+主语？答语是主语+谓语+数词+years old.”注意句子的英文语序。

如：“How old is your teacher? He is 30 years old.”
2. How are you?与How old are you?的区别，前者是询问身体状况的用语，回答是I'm f ine/OK/all right/very well.,而后者是询问年龄的用语，它的回答是I'm twelve (years old).,也就是I'm +数字(years old)。

3. Are you...?是一般问句，意思是“你是……吗？”可用来询问姓名、职业、身份等许多情况。

回答用Yes表肯定，或用No表否定。

否定回答中由于am后有一个词not，所以No, I am not.常缩写成No, I'm not.其中I'm是I am的缩写形式。

而在肯定回答中，由于am 后面没有词，所以Yes, I am.不能缩写成Yes, I'm.
4.含有be动词的一般问句的构成是把be动词放到句首，句末用问号，句子读升调。

肯定回答是：Yes, 主语代词+be.否定回答是：No, 主语代词+be+not.否定回答中，主语代词和be 可以缩写，也可将be和not缩写，但am和not不可缩写。

肯定回答则不能缩写。

5 .两个形容词间用and 连接，表示“……又……”，如：big and strong, small and th in, tall and slim。

三个以上形容词则在最后一个形容词前用and，其余的形容词之间用逗号。

如：He is big, tall and strong.
6. big 与small，thin 与fat，short与long ，short与tall，sad与happy是反义词，而thin 与slim是同义词。

7. be from=come from, e.g. She's from England.=She comes from England.需注意的是from 后面的词一定是名词。

这儿有一些有关国家的名词，如：America, England, Chin a, Japan, France.
8. I have two new friends.中的have 是“有”的意思，表示所属关系。

可以表示“某人拥有”或“某物具有”。

I, We, You,They和复数名词后面用have，She, He, It 和单数名词后面用has，如：A desk has four legs. They have a new house.
9. Let sb. do sth.常用于表示主动提供帮助，或提建议、请求等。

Let 后跟动词原形，是省掉了不定式符号to的动词不定式。

例如：Let's play a game. Let me carry it.
