情態(tài)動詞
概念：情態(tài)動詞是一種本身有一定的詞義，表示說話人的情緒、態(tài)度或語氣的動詞，但不能單獨作謂語，只能和其他動詞原形構(gòu)成復合謂語，沒有人稱和數(shù)的變化。
B1情態(tài)動詞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.
疑問句中， 把can 提到句首， 將can 與主語的位置對調(diào)。
Can you speak any foreigner languages ?Can you solve this Maths problem ? I’m sorry, I can’t
B2 情態(tài)動詞may 與may not
在請求對方的許可， 或是準許你做某事時， 常用情態(tài)動詞may 和can. may 比較正式，can 較常用且更口語化一些。 如：
May I leave work early today? - 我今天可以早點下班嗎？
Yes, You may - 你可以 No, you may not - 你不可以
Can I open a window ? - 我可以開扇窗嗎？
Yes, you can - 你可以 No, you can’t - 你不可以
You may / can use my dictionary. 你可以用我的詞典。
You may not/ cannot use my computer. 你不可以用我的電腦。
B3 情態(tài)動詞 must 與must not
must 用以表示“必須做某事” 或“一定要做某事”， 具有強制性， 表達一種責任或義務或表示很有必要做某事； 或在提出建議時使用， 意為“應該； 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 用于一般疑問句中，其肯定和否定回答應引起我們的注意。
Must I go now ? - 我現(xiàn)在一定要走嗎？Yes, you must .- 是的；你一定要走。
- No, you mustn’t - 不,你不可以走。
Must I finish reading the book this week ?
-Yes, you must -No, you needn’t
