情態(tài)動(dòng)詞
概念：情態(tài)動(dòng)詞是一種本身有一定的詞義，表示說(shuō)話人的情緒、態(tài)度或語(yǔ)氣的動(dòng)詞，但不能單獨(dú)作謂語(yǔ)，只能和其他動(dòng)詞原形構(gòu)成復(fù)合謂語(yǔ)，沒(méi)有人稱和數(shù)的變化。
B1情態(tài)動(dòng)詞can 與cannot
我們用can 表示某人具備某種能力做某事。 如：
I can play basketball.
We can finish the work in 20 minutes.
其否定形式為cannot 或can’t . 如:I cannot swim.
I’m afraid I can’t think of more examples to support this argument.
疑問(wèn)句中， 把can 提到句首， 將can 與主語(yǔ)的位置對(duì)調(diào)。
Can you speak any foreigner languages ?Can you solve this Maths problem ? I’m sorry, I can’t

在請(qǐng)求對(duì)方的許可， 或是準(zhǔn)許你做某事時(shí)， 常用情態(tài)動(dòng)詞may 和can. may 比較正式，can 較常用且更口語(yǔ)化一些。 如：
May I leave work early today? - 我今天可以早點(diǎn)下班嗎？
Yes, You may - 你可以 No, you may not - 你不可以
Can I open a window ? - 我可以開(kāi)扇窗嗎？

B3 情態(tài)動(dòng)詞 must 與must not
must 用以表示“必須做某事” 或“一定要做某事”， 具有強(qiáng)制性， 表達(dá)一種責(zé)任或義務(wù)或表示很有必要做某事； 或在提出建議時(shí)使用， 意為“應(yīng)該； 得”。 如:
We must obey the school rules.
The windows are very dirty. I must clean them.
We must go to the bank today. We haven’t got any money.
must 的否定形式是mustn’t, 表示“禁止”， “決不允許”，具有強(qiáng)制性。 如:
I must hurry, I mustn’t be late.
You mustn’t forget to phone Julia.
must 用于一般疑問(wèn)句中，其肯定和否定回答應(yīng)引起我們的注意。

- No, you mustn’t - 不,你不可以走。
