注意:could不表示时态
1)提出委婉的请求,(注意在回答中不可用could)。
--- Could I have the television on?
--- Yes, you can. / No, you can't.
2)在否定,疑问句中表示推测或怀疑。
He couldn't be a bad man.
他不大可能是坏人。
3 比较may和might
1) 表示允许或请求;表示没有把握的推测;may 放在句首,表示祝愿。
May God bless you!
He might be at home.
注意: might 表示推测时,不表示时态。只是可能性比may 小。
2) 成语: may/might as well,后面接不带to 的不定式,意为"不妨"。
If that is the case, we may as well try.
典型例题
Peter ___come with us tonight, but he isn't very sure yet.
A. must B. may C. can D. will
答案B. 表可能性只能用may. 此句意可从后半句推出。本回答被网友采纳
