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。
