4种基本的状语从句的用法,你知道吗?
一、地点状语从句(Adverbial Clause of Place) 引导地点状语从句的从属连词和词组有where, wherever, everywhere等。 【例句】 Where there is a will, there is a way. Wherever John happens to be, he can make himself at home. Where the ancients knew nothing, we know a little.
Everywhere the visitors went, they were warmly received.
二、条件状语从句(Adverbial Clause of Condition) 引导条件状语从句的从属连词和词组有if, unless, suppose, in case, so long as, in case, so far as, on condition that, provided (that), providing that等。 【例句】 If the dam had broken in the flood last year, there would have been great loss of life and property. Provided (that) he wins the support of the minority groups, he will be able to win the election. In case it rains, we won’t be able to go there on foot. You can go out, as/so long as you promise to be back before eleven. 提示:if 和unless的区别:if表示正面的条件,意为“如果”;unless表示反面的条件,意为“除非,如果不”,语气较强。 【例句】 If he doesn’t follow our advice, we won’t accept his invitation.
We won’t wait for him long unless he comes before 6.
三、原因状语从句(Adverbial Clause of Cause) 引导原因状语从句的从属连词和词组有:as, because, since, seeing that, considering that, now that, not that…but that等。 【例句】 As there was no answer, I wrote again. Since the speaker can’t come, we’ll have to cancel the meeting. Because it was wet, he didn’t go out for a walk that day. 提示:because表示原因的语气最强,as和since(较正式)表示原因,语气较弱,其原因对方略知一二。For在引导并列句时可以和because相互替换,但因for是并列连词,因此不能用于句首,只能用于连接表示原因的并列句。 【例句】 I have got the position for just two months. My boss doesn’t trust me because I am new to him and his office, I think.
Since so many people are absent, we had better put the meeting off.
四、让步状语从句(Adverbial Clause of Concession) 引导让步状语从句的从属连词和词组有as, though, although, no matter, even if, even though, however, whatever, while, granted (granting) (that)等。 【例句】 He passed the examination although he had been prevented by illness from studying, Though he should stand alone, he will never yield. I shouldn’t have time to see him even if he were here. Rich as he is, Mr. Johnson is by no means a happy man. 提示:whatever, wherever, whichever等带-ever的连接代词和连接副词的强调让步用法(= no matter what),常译为:“无论……”。 【例句】 Wherever you go, there I go! Whoever of you comes in first, he or she will receive a prize. 提示:动词be可以置于句首引出让步状语从句,现只见于书面语中。 【例句】 Be it very late, we must finish the work. Electronic computers work on the binary system(二进制) be they large or small.
