情态动词
概念：情态动词是一种本身有一定的词义，表示说话人的情绪、态度或语气的动词，但不能单独作谓语，只能和其他动词原形构成复合谓语，没有人称和数的变化。
B1情态动词can 与cannot
我们用can 表示某人具备某种能力做某事。 如：
I can play basketball.
We can finish the work in 20 minutes.
其否定形式为cannot 或can’t . 如:I cannot swim.
I’m afraid I can’t think of more examples to support this argument.
疑问句中， 把can 提到句首， 将can 与主语的位置对调。
Can you speak any foreigner languages ?Can you solve this Maths problem ? I’m sorry, I can’t
B2 情态动词may 与may not
在请求对方的许可， 或是准许你做某事时， 常用情态动词may 和can. may 比较正式，can 较常用且更口语化一些。 如：
May I leave work early today? - 我今天可以早点下班吗？
Yes, You may - 你可以 No, you may not - 你不可以
Can I open a window ? - 我可以开扇窗吗？
Yes, you can - 你可以 No, you can’t - 你不可以
You may / can use my dictionary. 你可以用我的词典。
You may not/ cannot use my computer. 你不可以用我的电脑。
B3 情态动词 must 与must not
must 用以表示“必须做某事” 或“一定要做某事”， 具有强制性， 表达一种责任或义务或表示很有必要做某事； 或在提出建议时使用， 意为“应该； 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”， “决不允许”，具有强制性。 如:
I must hurry, I mustn’t be late.
You mustn’t forget to phone Julia.
must 用于一般疑问句中，其肯定和否定回答应引起我们的注意。
Must I go now ? - 我现在一定要走吗？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
