may和might的用法辨析
本文章由春喜在線(xiàn)英語(yǔ)于2017.6.6日編輯發(fā)布
may和might可以表示可能性和許可。might的語(yǔ)氣比may較婉轉(zhuǎn)。此外,may也可以接動(dòng)詞的完成形式,表示可能、說(shuō)不定已經(jīng)做某事。
【例如】
I thought it might be difficult for me to learn advanced mathematics. (可能性)
May I come in, sir? (許可)
She may have gone to the hospital.
Research findings show we spend about two hours dreaming every night, no matter what we ____during the day. (cet-4 1999,1)
A) must have done
B) should have done
C) would have done
D) may have done
情態(tài)動(dòng)詞后面加動(dòng)詞完成式,有不同意義。
must have done表示一定做過(guò)某事;
should have done表示本應(yīng)該做某事,含有批評(píng)的意思;
would have done主要用于虛擬語(yǔ)氣,表示對(duì)過(guò)去的虛擬;
may have done表示可能已經(jīng)作過(guò)某事。
根據(jù)句意:研究結(jié)果表明,我們每晚有兩個(gè)小時(shí)做夢(mèng),不管白天可能做了什么,情態(tài)動(dòng)詞后表示可能性,故答案應(yīng)為D。
