1) 表示允許或請求;表示沒有把握的推測;may 放在句首,表示祝愿。
May God bless you!
He might be at home.
注意: might 表示推測時,不表示時態(tài)。只是可能性比may 小。
2) 成語: may/might as well,后面接不帶to 的不定式,意為"不妨"。
If that is the case, we may as well try.
典型例題
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. 此句意可從后半句推出。
