2015年6月大學(xué)英語六級語法常考知識(5)

　　Only in this way, can you learn English well.

　　Only after being asked three times did he come to the meeting.

　　如果句子為主從復(fù)合句，則主句倒裝，從句不倒裝

　　Only when he is seriously ill, does he ever stay in bed.

　　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(shí)，不表示時(shí)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。
