基本环节：

Step1 Warming up 1.

Ask students some questions. T:I can spell all the words we have learnt. Can you do that?

S:Yes, I can. No, I cannot/can’t. 2.

Play the game.

What can you do? Tell the student behind you and ask if he/she can do it. The next student should repeat this with another student. e g : S1: I can swim ,can you swim? S2: Yes, I can. I can sing. Can you sing? S3: No, I can’t. I can dance. Can you dance? S4: …

Step2: Presentation A1 can and cannot We use the modal verbs can and cannot (can’t) to say we are able or unable to do something. A2: Read some sentences. A3: Do some grammar exercises. B1 may and may not We use may and may not to ask for and give permission. In less formal situations, some people like to use can and cannot (can’t) for the same purpose. May can be interchanged with “can”, but it’s a little more polite to use “may”.

B2: Read some sentences. B3: Do some grammar exercises. C1 must and must not

We use must and must not/mustn’t to tell people what to do or what not to do. C2: Read some sentences. C3: Do some grammar exercises. Work out the rule: After modal verbs such as can, may and must, we use the base form of a verb. Step3 Practice 1.

Let’s remember:

陈述句：肯定句:

I can/may/must have a rest.

否定句:

I cannot/can’t have a rest.

I may not have a rest.

I must not/mustn’t have a rest.

一般疑问句：

Can/May I have a rest?

Yes, you can/ may.

No, you cannot /can’t / may not.

Must I have a rest?

Yes, you must. No, you need not. /needn’t.

特殊疑问句:特殊疑问词+can/cannot/can’t/may/may not/must/must not/ mustn’t + you do?
