状语从句的用法如何使用状语从句(2)
五、原因状语从句
1. 引导原因状语从句的从属连词主要有because, as, since, seeing (that), now (that)等:
They can’t have gone out because the light’s on. 他们不可能出去了,因为灯还亮着。
Since you are going, I will go. 既然你去,我也去。
Now that we are alone, we can speak freely. 现在我们单独在一起,可以随便谈了。
2. 除以上提到的大家比较熟悉的引导原因状语从句的从属连词外,when有时也可引导原因状语从句,其意“既然”。如:
I can’t tell you when you won't listen. 既然你不想听,我就不告诉你了。
3. 有关原因状语从句还应注意以下几点:
(1) as 与 since, now that 一样表示双方都知道的原因,通常位于主句前,且均不可用于强调结构被强调。
(2) 当表示直接的因果关系,回答 why 时,或有 only, just, all, partly, not, but 等副词修饰时,或用在强调结构中都只能用 because。
(3) for 有时也可引出表示原因的分句,但它只能位于后面,对前一分句加以解释或推断。
(4) 不要受汉语意思影响将表示“因为”的连词与表示“所以”的 so 连用。
六、地点状语从句
引导地点状语从句的从属连词主要有where (在…的地方), wherever(无论什么地方), everywhere(每个…地方), anywhere(任何…地方)。如:
I’m not living where I was. 我不在原处住了。
You can’t camp where [wherever, anywhere] you like these days. 如今你可不能随便在哪儿宿营。
Everywhere I go, I find the same thing. 不管我走到哪里,我都发现同样情况。
2. 有的同学认为地点状语从句在平时见得不多,误认为考试不会涉及,但恰恰相反,地点状语从句却是英语考试经常考查的一个知识点。请看以下考题:
(1) When you read the book, you’d better make a mark _____ you have any questions.
A. at which B. at where C. the place where D. where
(2) After the war, a new school building was put up _____ there had once been a theatre.
A. that B. where C. which D. when
(3) You should make it a rule to leave things _____ you can find them again.
A. when B. where C. then D. there
(4) She found her calculator ______ she lost it.
A. where B. when C. in which D. that
以上四题均选where,其意为“在…的地方”,用以引导地点状语从句。
七、目的状语从句
1. 引导目的状语从句的从属连词主要有 in order that, so that, in case, for fear等。如:
I hired a boat so that I could go fishing. 我租了一条船去钓鱼。
Take your coat in case it rains (should rain). 带着雨衣以防下雨。
He studied hard in order that he could pass the exam. 他努力学习,是为了能通过考试。
2. 引导目的状语从句的 so that 有时可省so 或 that,即单独用 so 或 that 来引导目的状语从句。如:
Check carefully, so any mistake will be caught. 仔细检查,以便任何错误都可检查出。
Bring it closer that I might see it better. 拿近些,使我能看得清楚些。
八、结果状语从句
引导结果状语从句的从属连词主要有so that, so…that, such…that等。如:
He was so angry that he couldn't speak. 他气得话都说不出来。
He shut the window with such force that the glass broke. 他关窗子用力很大,结果玻璃震破了。
注:so…that和such…that中的that有时(尤其在口语中)可省略。

C. not to be handledD. not having been handled
4. This drug is less likely to cause side effects when ________ late in the day.

答案:
1.A 【解析】句意:如果有人让你看行李,马上通知警察。结合题干的结构和选项不难看出,此处考查"连词+非谓语动词"作状语的用法,由if可知,此处该结构作条件状语,ask与句子主语you(已经省略)为动宾关系,故只能用asked。其实,if asked…是if you are asked…的省略形式。
2.B 【解析】句意:当被问及对其教学工作的看法时,菲利普说他觉得它很有趣并且非常值得做。分析句子结构可知,When for his views about his teaching job是状语从句的省略形式。从句的主语和主句主语一致,且从句中含有be动词,故从句主语和be动词省略了,又因ask与Philip之间是逻辑上的动宾关系,故用ask的过去分词形式。
3.A 【解析】考查状语从句的省略。句意:欧洲的难民危机,如果处理不当的话,有可能会导致严重的社会问题。if条件句补充完整为"if it is not handled properly",根据主从句主语一致,从句中有be动词,可将从句的主语和be动词省略原则,该从句可省略it is,故A选项切题。
4.B 【解析】考查状语从句的省略式。句意:这种药晚些时候服用更不可能有副作用。这句话使用状语从句的省略式,完整的句子是when it is taken late in the day,省略主语和be动词,应用过去分词。故选B。
