状语从句省略具体分析。
一.时间状语从句的省略。
这类从句主要由when,while,as soon as,once,until等引导。
例如:When (she was) very young, she began to learn to play the piano.她很小时,就开始学习弹钢琴。
When arriving, send me a telegram. (When you arrive, send me a telegram.)到达之后,来个电报。
While (I was) at college, I began to know him, a strange but able student.我在上大学时就开始认识他,一个奇怪但有能力的学生。
Before leaving, turn off all the lights. (Before you leave, turn off all the lights.)走之前,请关闭所有的灯。
Whenever (it is ) possible, you should come and help. 不管什么时候只要有可能就来帮忙。
Don’t come in until (you are) asked to. 不叫你请你不要进来。
You should let us know the result as soon as (it is) possible. 你应尽快让我们知道结果。
二.地点状语从句中的省略。
主要由where, wherever引导。
例如:1.He is always ready to help others wherever (he is) needed.2.You can add some words to your composition where (it is) necessary.三.条件状语从句的省略。
主要由if,unless引导。
例如:1.She won't go to his birthday party unless (she is ) invited.2.The news is quite important to us, if (it is) true.但若if引导的是表示假设的虚拟条件句,虽具备条件,可不能用于这类省略。
这时如果if从句的谓语动词中含有were,had,should,则可以用倒装省略,即将were,had或should提到句首,而将连词if省略。
例如:Were it not for you, I would also go there with them.Had you come here earlier, you would have met him.Should it be fine tomorrow, we would go for an outing.另外,当once作"一旦,一经"解,连接时间或条件状语从句,其主语与主句的主语相同或其主语为it + be时,常省略从句中的主语或it + be。
例如:Once (it was) published, his work became famous for the absence of rhyme at the end of each line.Once (you) lose confidence, you can never expect to do your work well.四.让步状语从句的省略。
主要由though,although,however,whatever,even if,even though,no matter how/what引导。
例如:1.Though (he had been) defeated many times, he didn't lose heart.2.They worked very hard, though (he was) still rather weak.与if引导的虚拟条件从句不能用这类省略一样,as引导的让步状语从句同样不能省略。
不过如果让步状语从句由as引导时,从句中的表语(一般是形容词或名词)或状语必须提前到as前,构成倒装。
如果作表语的是单数可数名词,则还须省略不定冠词。
例如:Poor as he was, he was honest.Hard as he tried, he still failed.Much as I like her, I won't marry her.Child as he is, he can express himself in good English.五.原因状语从句的省略。
主要由because引导。
例如:1.He decided not to watch the foot ball match because (he was) not himself.2.I forget to post the letter for you because (I was) too busy.六.比较状语从句的省略。
主要由as,than引导。
例如:1.In winter it is much colder in Beijing than (it is) in Shanghai.2.The project was completed earlier than (it was) expected.3.Mary is not so shy as (she was) a year ago when I first met her.七.方式状语从句的省略。
主要由as,as if引导。
例如:1.The old man sat at the corner alone, as if (he was) thinking of something.2.English is not so difficult to learn, as (it is) generally supposed.综上所述,不难发现:这些省略形式的状语从句大都以"从属连词+形容词(副词、介词短语、不定式短语、现在分词或过去分词)"构成的。
省略后的句子不仅意思清楚,不会引起误解,而且结构紧凑,语言简练流畅,读起来明快生动。
