情態動詞

概念：情態動詞是一種本身有一定的詞義，表示說話人的情緒、態度或語氣的動詞，但不能單獨作謂語，只能和其他動詞原形構成複合謂語，沒有人稱和數的變化。

B1情態動詞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.

其否定形式爲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。

Can you speak any foreigner languages ?Can you solve this Maths problem ? I’m sorry, I can’t

B2 情態動詞may 與may not

在請求對方的許可， 或是准許你做某事時， 常用情態動詞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， 意爲“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 用於一般疑問句中，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
