Review of adverbials and adverbial clauses 状语是用来修饰动词, 形容词, 副词或整个句子的成分:一般表示时间, 地点, 方式, 程度, 条件, 目的, 结果, 让步, 伴随情况等意义。
状语的位置
英语中的状语在句中的位置比较灵活:修饰形容词的状语, 通常放在所修饰的词之前;修饰动词的状语, 一般放在所修饰的动词之后。但有些副词如always, often, usually, never, ever等作状语时,则放在实意动词之前, 助动词, be动词或情态动词之后。Adverbial clauses 状语从句在主从复合句中修饰主句的动词、形容词或副词等,按意义分为时间、地点、原因、目的、结果、条件、让步、方式、比较等状语从句。 时间状语从句
引导时间状语从句的从属连词有after,
as, before, once, since, till, until,
when, whenever, while, as soon as, no
sooner… than…, hardly… when…, scarcely… when…等,以及名词短语the moment, the instant, every time等。如:
I saw him when/ while he was going out of the room.
在他走出房间时我碰见了他。
Edison’s mother had been a teacher before she got married.
爱迪生的妈妈结婚前是位老师。 注意:
no sooner… than…, hardly… when…, scarcely… when… 这三个结构意为“一…就…”,相当于as soon as,均可引导时间状语从句,但只能用于过去时,即主谓语用过去完成时,从句用一般过去时。No sooner, hardly, scarcely置于句首时,主句要部分倒装。 我一到家,天就下起雨来了。可译为:
As soon as I came home, it began to rain.
I had no sooner come home than it began to rain.
I had hardly /scarcely come home when it began to rain.
No sooner had I come home than it began to rain.
Hardly /scarcely had I come home when it began to rain.2. 地点状语从句
地点状语从句通常由where, wherever 等引导。如:
He lived where he liked.
他住在他喜欢的地方。
Where there is a will, there is a way.
有志者,事竟成。(谚语)
Wherever they went, they were warmly welcomed.
他们所到之处都受到热烈欢迎。3. 原因状语从句
原因状语从句通常由because, since, as, now that等引导。如:
He didn’t attend the meeting because he had too much work to do.
他因为要干的活太多没来参加会议。
Since he can’t answer the question, you’d better ask someone else.
既然他回答不了这个问题,你最好问别人吧。As I haven’t seen the film, I can’t tell you what I think of it.
由于我没看过这部电影,所以谈不出对它有什么看法。
Now that you have come, you may stay. 你既然来了,就留下吧。 注意:
for也可表“原因”,语气较弱,有时可与because换用,但它是并列连词,它连接的句子并不总是原因,有时可能对前面的分句提出推断的理由,不能回答why 引导的疑问句,它连接的分句只能后置,且前面有逗号。
The ground is wet, for it rained last night.
地面很湿,因为昨天晚上下雨了。(表原因,可用because代替)It rained last night, for the ground is wet.
昨天晚上下雨了,因为地面很湿。(提出判断的理由,“地湿”不是“下雨”的原因,不可用because代替)4. 目的状语从句
目的状语从句常由so that, in order that, so, that, in case(以防、以免),lest(以防),for fear that(以防、以免)等引导。如:

Although, though, as三者均可引导让步状语从句,意为“虽然”,“尽管”。although和though引导的让步状语从句放在主句前后均可,as引导的让步状语从句一般放在句首;although引导的让步状语从句不倒装, though引导的可倒可不倒,as引导的必须倒装,且如果从句中单数名词或形容词最高级作表语,倒装时不再用冠词; although和though引导的让步状语从句可用虚拟语气,as而则不可。 8. 方式状语从句
