三、精讲课文

1、Do you want any meat today?【回顾Lesson 47】助动词do 的用法。

2、-Do you want beef or lamb? -Beef, please.

【回顾Lesson 6】选择疑问句，前升后降，选择一个答案来回答。

例句：-Do you like apples or bananas? -Bananas.

3、I like lamb, but my husband doesn't (like lamb).

第三人称单数(He/She/It)时，助动词要用does (doesn ’t = does not)，然后动词要还原。 She likes red.→She doesn ’t like red.→-Does she like red? -Yes, she does. / No, she doesn ’t. He wants beef.→He doesn ’t want beef.→-Does he want beef? -Yes, he does. / No, he doesn ’t.

4、What about some steak? 【口语】What about...? …怎么样？（联系上下文）

5、This is a nice piece (of steak). 一块，一片a piece of...

6、Give me that piece. = Give that piece to me. 【回顾】双宾语。祈使句。

7、And a pound of mince, too.【回顾Lesson 41】论磅称。

half a pound of...

8、Do you want a chicken?

chicken：①小鸡= chick（可数名词）；公鸡cock，母鸡hen ②鸡肉（不可数名词）9、My husband likes steak, but he doesn't like chicken.

注意：my husband = he，所以动词要用第三人称单数形式。而助动词要用does。

例句：My sister likes apples, but she doesn’t want one.

10、To tell you the truth, Mrs. Bird, I don't like chicken, either!

【口语】to tell you the truth 说实话、老实说= to be honest with you

too 也（肯定句中）VS（否定句中）也either

例句：He likes steak, and I like it too.

He doesn’t like steak, and I don’t like it either.

四、总结与练习

1、肉类meat（不可数名词）：

beef, steak, lamb, pork, mince, chicken

2、助动词does的用法：在第三人称单数做主语的句子中，帮助变为否定句和疑问句。

例如：（1）He likes eggs. →He doesn’t like eggs.

→-Does he like eggs? -Yes, he does. No, he doesn’t.

→He likes eggs, but he doesn’t want one.

（2）She wants milk. →She doesn’t want milk.

→-Does she want milk? -Yes, she does. No, she doesn’t.

→She likes milk, but she doesn’t want any.
