情態(tài)動(dòng)詞will和would在英語語法中所表達(dá)的意思幾乎相同,但是,在具體應(yīng)用中還是有一定區(qū)別的:
1、表示請(qǐng)求、建議等,would比will委婉客氣。如:
Would you pass me the book?
2、表示意志、愿望和決心。如:
I will never do that again.
我再也不會(huì)做那了。
They asked if we would do that again.
他們問到,我們是否愿意再次做那。
3、 用“will be”和“will(would) + have + 過去分詞”的結(jié)構(gòu)表示推測(cè),主要用于第二、三人稱。前者表示對(duì)目前情況的推測(cè),后者表示對(duì)已經(jīng)完成的動(dòng)作或事態(tài)的推測(cè)。如:
This will be the book you want.
這本書應(yīng)該是你想要的。
He will have arrived by now.
他現(xiàn)在應(yīng)該已經(jīng)到了。
The guests would have arrived by that time.
那時(shí),客人們應(yīng)該都到了。
I thought you would have finished this by now.
我認(rèn)為你現(xiàn)在應(yīng)該已經(jīng)完成了。
4、will表示習(xí)慣、請(qǐng)求,固有性質(zhì)等。
Everyday he will sit here hour after hour doing nothing.(習(xí)慣)
他每天就坐在那里,卻什么事也不做。
Will you help me with my English?(請(qǐng)求)
你能幫我提高我的英語嗎?
The door won't open. (固有性質(zhì))
這個(gè)門打不開。
5、Would可表示過去反復(fù)發(fā)生的動(dòng)作或某種傾向。Would表過去習(xí)慣時(shí)比used to正式,并沒有“現(xiàn)已無此習(xí)慣”的含義。如:
The wound would not heal.
這個(gè)傷口愈合不了。
During the vacation he would visit me every week.
假期里,他每個(gè)星期都會(huì)看我。
6、表料想或猜想。如:
It would be about ten when he left home.
當(dāng)他離開家的時(shí)候大概是十點(diǎn)。
What would she be doing there?
她去哪里干什么?
