在英语的实际应用中,有时上下文或当时的语境能够帮助我们理解所写的内容,所以有的时候可以省去一个或更多的句子成分,但前提是不影响句子的理解和可读性,因此若有具体的上下文支撑,是可以省去部分成分。
跟定语从句的“瘦身”原理类似,状语从句也可以“瘦身”,这种“瘦身”原理就是省略。
若从句的主语与主句的主语一样,那么通常可以省略从句的主语或助词,然后动词做相应的变化,例如:While Sarah was studying, she fell asleep.萨拉在学习时睡着了。
解析:此句可以省略,因为从句中的主语和主句中的主语都是 Sarah,因此可以省略为 While studying, she fell asleep,但是以下这句不能省略,例如:While Sarah was talking, I fell asleep.萨拉说话的时候,我睡着了。
解析:从句中的主语 Sarah 和主句的主语 I 不一样,所以不能省略。
一、状语从句带 be 动词的省略在带 be 动词(am, is, are, was, were, been, being)的状语从句中,直接省略主语和 be 动词,例如:1. 萨拉在学习时睡着了。
While she was studying, Sarah fell asleep.省略:While studying, Sarah fell asleep.2. 尽管他迟到了,他还是被允许去看电影。
Although he was late, he was admitted to the movie.省略:Although late, he was admitted to the movie.二、状语从句不带 be 动词的省略在不带 be 动词(am, is, are, was, were, been, being)的状语从句中,直接省略主语,然后把对应的动词变成 -ing 形式,例如:1. 杰克读完这本书后,把它放回书架上。
关于状语从句的省略问题在英语学习中我们常见到状语从句省略问题,但并不是所有的状语从句都可采取省略式,可采用省略式的有:1.when ,while, till, until, once 所引导的时间状语从句。
2.if, unless 所引导的条件状语从句。
3.although, though, even if , even though所引导的让步状语从句。
4.as if, as though所引导的方式状语从句。
5.than 所引导的比较状语从句。
状语从句使用省略的四种情况:一:当从句的主语和主句的主语一致(从句的谓语常含有系动词be)时,常把从句的主语和系动词一起省略,省略后从句呈现出:Conj+doing /done/adj/adv/to do/n/介短Eg:1.You must be careful when (you are )crossing the street.2.When (he was) asked why he was late, he said he had missed thetrain.3.When /while (he was ) in Paris, he picked up some French.4.Once ( it is ) seen, it will never be forgotten.5.Unless ( I am ) invited, I won’t attend his wedding.6.Though (he was )young/a boy, Tom knows a lot.7.Even if/though (he is )invited, he won’t go.8.He must be somewhere around if (he is )not here/in the office.9.They looked around the room as if /though (they were)looking forsomething.10.H e opened his mouth as if /though (he was) to say something.11.H e is much taller than (he is) expected.12.I can’t do it until (I am) told how to.13.W hen/while (he was) still a boy, he began to support himself.14.I f (water is )heated to a higher temperature, water will be turnedinto steam.15.T he research is so designed that once_____, nothing can be doneto change it.A beginsB having beganC beginningD begun(D)16.

The flowers will die unless ______every day .A wateredB wateringC waterD to water (A)二:当从句的主语和主句的逻辑主语一致时,也可把从句省略为Conj+doing /done/adj/adv/to do/n/介短,此种用法主要是用来描述或说明某种现象或情况,是“对事不对人”,而第一种情况是就具体的人或事来说明的。
