語法精析
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(wǎng)購了，但是去年她還不會。
(2)表示猜測，意為“可能”，一般用于疑問句和否定句(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(xiàn)在可以走了嗎？
——是的，可以。
(4)用于肯定的陳述句中，表示理論上或習(xí)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(xí)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。
We cannot thank you too much for what you’ve done for us.
對于你們?yōu)槲覀兯龅囊磺校覀冊趺锤屑つ銈兌疾贿^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.
——晚飯后我可以玩電腦游戲嗎？
——是的，可以。/不，不行。
(2)表示把握不大的推測，意為“可能”，用于肯定句。
might語氣更加不肯定，指現(xiàn)在或?qū)�，只有在賓語從句中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用于祈使句表示祝愿。
May you succeed.祝你成功。
