Present the key sentences to the class. Read them aloud with the whole class.

Step 2　Grammar summary

情态动词must, can, need等 

一、must的用法

must表示“必须；一定”，可用于肯定句、否定句或疑问句。must的否定形式是must not，可缩略为mustn’t，表示“不能；禁止”。

We must clean our classroom every day.

我们必须每天清扫教室。

You mustn’t do any cleaning on the first day of the Spring Festival.

在大年初一你一定不能打扫卫生。

Must we wait for them here?

我们必须要在这儿等他们吗？

[注意]

以must开头的一般疑问句，肯定回答通常用must，否定回答通常用needn’t或don’t have to。

— Must I finish my homework before I go out to play?

  我在外出玩耍前必须要完成家庭作业吗？

— Yes, you must. / No, you needn’t.

  是的，你必须(完成)。/ 不，你不必(完成)。  

二、can的用法

can表示“许可；可以”，可用于肯定句、否定句或疑问句。can的否定形式是can not或cannot，可缩略为can’t，表示“不能；不可以”，在语气上弱于mustn’t。

You can take the book out of the library.

你可以把这本书带出图书馆。

You can’t write your name here.

Can I have a look at your new camera?

can除了表示许可或请求许可之外，还常用来表示能力。

[注意]

以can开头的一般疑问句，肯定回答用can，否定回答用can’t。

—Can we go home now?

  我们现在能回家吗？

—Yes, you can. / No, you can’t.

  是的，你们可以。/不，你们不行。

三、need的用法

need作情态动词，意为“需要”，常用于否定句或疑问句。need的否定形式为need not，可缩略为needn’t，意为“不需要；不必要”。

If you want to look up the words, you need to buy a dictionary.

如果你想查这些单词，你需要买一本词典。

You needn’t worry about your health.

你不必担心你的健康。

Need we ask the policeman for help?

我们需要求助那位警察吗？

[拓展]

need还可用作实义动词，意为“需要”。need sth. 意为“需要某物”；need to do sth. 意为“需要做某事”。

I need your help. 我需要你的帮助。

We need to buy some more food and drink. 我们还需要再买一些食物和饮料。

[注意]

以need开头的问句，肯定回答通常用must，否定回答通常用needn’t。

— Need I tell Daming about it?

我需要把这件事告诉大明吗？

— Yes, you must. / No, you needn’t.

  是的，你必须告诉他。/ 不，你没有必要告诉他。

四、must与have to的区别

(1) must侧重于说话者主观看法，认为有必要或有义务去做某事；have to侧重于客观需要，含有“不得不”之意。

We must work hard. 我们一定要努力学习。

My bike was broken, so I had to go to school on foot.

我的自行车坏了，所以我不得不步行去上学。
