文法精析

1.can與could的用法

(1)表示能力(could是過去式)。

My grandmother can do some shopping on the Internet，but she couldn’t last year.

我奶奶會網購了，但是去年她還不會。

(2)表示猜測，意為“可能”，一般用於疑問句和否定句(could是過去式)。

Can this news be true？這則消息是真的嗎？

(3)表示請求和許可(could表示更委婉的語氣，回答時只能用can)。

—Can/Could I go now?

—Yes，you can.

——我現在可以走了嗎？

——是的，可以。

(4)用於肯定的陳述句中，表示理論上或習慣上的可能性。

As we all know，anyone can make mistakes.我們都知道，任何人都可能犯錯。

(5)習慣用法「cannot...too...」表示「無論怎樣…都不過分，越…越好」。有時cannot可用can never替代品。

We cannot thank you too much for what you’ve done for us.

對於你們為我們所做的一切，我們怎麼感激你們都不過分。

2.may與might的用法

(1)表示允許、許可。 might在語氣上比may更委婉。以may/might開頭的問句在否定回答中要用mustn’t/can’t。

—May/Might I play the computer games after supper?

—Yes，you may./No，you mustn’t/can’t.

——晚餐後我可以玩電腦遊戲嗎？

——是的，可以。 /不，不行。

(2)表示把握不大的推測，意為“可能”，用於肯定句。

might語氣更不肯定，指現在或將來，只有在受詞子句中might do (be)才表示過去的可能性。

①I think he may come tomorrow.我認為明天他可能會來。

②He told me he might be late.他告訴我他可能會遲到。

(3)may用於祈使句表示祝福。

May you succeed.祝你成功。
