A policeman approached Jimmy and told him he ought to have gone along a side street as Jumbo was holding up traffic.
問：1,句中as 如何理解,怎么翻譯好?2,as這個介詞用法,舉例說明.3 ought to have gone
have gone 為什么用過去現(xiàn)在完成時?ought to go along 不可以嗎?應(yīng)該的內(nèi)容為什么不用一般時態(tài)?
答：本題句出自新概念英語第二冊第65課：
Last Christmas,the circus owner,Jimmy Gates,decided to take some presents to a children's hospital.Dressed up as Father Christmas and accompanied by a 'guard of honour' of six pretty girls,he set off down the main street of the city riding a baby elephant called Jumbo.He should have known that the police would never allow this sort of thing.A policeman approached Jimmy and told him he ought to have gone along a side street as Jumbo was holding up the traffic.
一個警察走過來告訴吉米,他應(yīng)該走一條小路,因為江泊阻礙了交通.
1.as在這里表示原因.譯作“因為”,“由于”.
2.as 在這里不是介詞,是從屬連詞.用法很多.可從詞典上摘抄.
3.ought to have gone ...不叫過去現(xiàn)在完成時（沒有這種說法）.它相當(dāng)于should have gone ...
是情態(tài)動詞后用完成式,表示“本應(yīng)該做某事”,是針對過去而言的.should +動詞原形,表示現(xiàn)在或?qū)?如：You should study hard.你應(yīng)該努力學(xué)習(xí).（現(xiàn)在和將來）.如果你以前沒有好好學(xué)習(xí),這次沒考好.我說：You should have studied hard.
