從零開始學(xué)語法：情態(tài)動詞can與may的用法

can 的用法

一、表能力，有“能，會，能夠”的意思。例如：

-Can you drive a car? 你會開車嗎?

-Yes, I can. 我會。/ No, I can't. 我不會。

二、表允許，在口語中代替may，有“可以”的意思。

(見下面 may 的用法第四點)

三、表示可能性，常用于否定句和疑問句。例如：

很多同學(xué)都不太清楚 can 與 be able to 的異同吧，趕快來學(xué)習(xí)一下吧>>

may 的用法

一、表示許可或征求對方的許可，有“可以”的意思。例如：

二、回答以 may 開頭的疑問句有如下表達(dá)法：

-May I smoke here? 我可以在這兒抽煙嗎?

-Yes, you may. / Yes, please. 請抽吧。

-No, you can't. / No, you mustn't. / No, you'd better not. 請不要抽煙。

三、表示猜測，通常只用于陳述句。例如：

三、表推測，暗含有很大的可能性。例如：

He must be ill. He looks so pale. 他肯定是病了。他的臉色那么蒼白。

注意：之前我們說過 may 也可以表猜測，但是 may 暗含的可能性較小，must 暗含的可能性較大。另外否定的猜測是用can't。例如：

二、在疑問句和否定句中，have to 多用助動詞 do 構(gòu)成，must 則直接提前或加not。例如：

Did he have to do it? = Must he do it? 他得做那件事嗎?

而且在否定句中，have to 表不需要，must 表不允許：

You mustn't go there? 你不可去那兒。
