教学过程

Step 1　Language practice

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

Step 2　Grammar summary

Sum up the grammar together with the whole class.

情态动词may/ might表示“可能”

一、什么是情态动词

情态动词是一类表示说话人对有关行为或事物的态度或看法的词，认为其可能、应该或必要等。情态动词本身有一定的含义，但它不能单独使用，也无人称和数的变化，后接动词原形。

I can swim. (情态动词can表示能力）我会游泳。

May I come in?(情态动词may表示请求许可）我可以进来吗？

We should practise English every day. (情态动词should表示应该）

我们应该每天练习英语。

二、情态动词may / might表示“可能”

may和might都可以表示某事可能发生或某人可能做某事。might表示的可能性比may表示的可能性小一些。

Daming and Lingling may be in the library. 大明和玲玲可能在图书馆。

There may be a few showers in the afternoon. 下午可能有阵雨。

Miss Lin might know the answer. But I am not sure.

林老师可能知道答案，但我不确定。

My cousin may not want to go swimming with me.

我表弟可能不想和我去游泳。

[拓展]

英语中其他表示可能的方式：

(1)主语+will +probably / possibly +谓语动词 +其他.

We will probably play football tomorrow afternoon.

明天下午我们很可能踢足球。

It will possibly be cold. 天气可能会很冷。

(2) It is possible to do sth.

It is possible for them to visit New England this summer.

他们今年夏天可能要去游览新英格兰。

probably表示“很可能”，所表示的可能性比possibly要大。

One possible answer:

Dear Lucy,

It’s good to hear that you may visit China. I think the best time to come is in autumn. Most of the places in China are neither too hot nor too cold in this season. It’s the most comfortable time to travel. If you’re going to visit South China, you should probably bring an umbrella because there may be some rain.

You might like to stay in a hotel. You won’t have to pay much for it because hotels are not very expensive here. But I also invite you to stay in my home. I’m happy to be your guide during the holiday.

Looking forward to hearing all about your travel plans.

Best wishes,

Daming
