英语中的省略为了避免重复,英语句子中某些部分可以省略。
常见的省略有以下几种:一、状语从句中的省略在时间、条件、让步及比较状语从句中,如主句和从句主语一致(或从句主语是it),且从句含be动词时,可将从句中的主语和be动词省略,从而构成“连词+ 分词/形容词/副词/介词”结构。
这里常见的连词有when/while/as/if/unless/once/although/though/than等。
When (water is )heated, water is turned into vapor. 水加热时变成气体。
He works very hard though(he is)rather weak. 他尽管体弱,但他十分努力地工作。
He came earlier than(he had been)expected. 他来得比预料的要早。
考例:①The research is so designed that once ____ nothing can be done to change it.A. beginsB. having begunC. beginningD. begun②If you go to Xi' an, you will find the palaces there more magnificent than commonly ___ .A. supposingB. supposedC. to supposeD. suppose分析:①D。
once后省略了the research is begun ②B。
比较状语从句中的完整形式是:than they are commonly supposed。
二、并列结构的省略1.并列结构一般由and, or, but等连接,他们可以连接单词、短语或分句,其中相同成分出现时可以被省略。
One of the sides of the board should be painted yellow, and ____.A.the other is whiteB. another whiteC. the other whiteD. another is white选C。
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。
状语从句xx省略状语从句得省略原则主要就是:如果从句中得主语与主句中得主语一致,就可以经过一定得变动把状语从句中得主语与谓语得一部分或全部省略,从而使语言更加简洁、明了。
现就把各种状语从句得省略现象列举如下:一、时间状语从句xx省略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。
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她,一个奇怪但有能力得学生。
When arriving, send me a telegram、(When you arrive, send me a telegram、)到达之后,来个电报。
Before leaving, turn off all the lights、(Before you leave, turn off all the lights、)走之前,请关闭所有得灯。
Don’t come in until (you are) asked to、不叫您请您不要进来。
Whenever (it is )possible, you should come and help、不管什么时候只要有可能就来帮忙。
You should let us know the result as soon as(it is) possible、您应尽快让我们知道结果。
注:as在引导时间状语从句时,没有这种省略现象。
我们不可说As walking, she found a nice shining thing on the ground、二、地点状语从句xx省略地点状语从句得省略常用下列结构:where(ver) possible, where(ver) necessary,Lay these books where possible you can find them easily、把这些书放在您可能容易找到得地方。

状语从句的省略与强调句型状语从句是英语中常用的一种句子结构,它可以在句子中充当状语,用来修饰动词、形容词、副词等。
在使用状语从句时,有时可以省略部分成分,从而使句子更简洁明了。
同时,通过加入强调句型,我们可以突出状语从句中的重要信息,提高表达的效果。
本文将探讨状语从句的省略与强调句型。
1. 状语从句的省略在英语中,状语从句可以根据情况省略主语、谓语、宾语等成分,以简化句子结构。
状语从句的省略主要体现在时间状语从句、地点状语从句和条件状语从句中。
1.1 时间状语从句通常情况下,时间状语从句与主句之间存在一个连词,如when (当)、while(当...的时候)、after(在...之后)、before(在...之前)等。
但是,当主句中的谓语动词为延续性动词(继续进行的动作或状态)时,时间状语从句的连词和主句的谓语动词可以省略。
例如:- He was reading a book when I arrived.(当我到达时,他正在看书。
)- He was reading a book I arrived.(当我到达时,他正在看书。
)1.2 地点状语从句地点状语从句表示行为发生的地点,通常使用连词where(在哪里)、wherever(无论在哪里)等引导。
然而,在某些情况下,地点状语从句可以省略引导连词where。
例如:- He lives in the house where he was born.(他住在他出生的房子里。
)- He lives in the house he was born.(他住在他出生的房子里。
)1.3 条件状语从句条件状语从句表示主句发生的条件,通常使用连词if(如果)、unless(除非)等引导。
有时,在条件状语从句中的谓语动词是be动词时,可以将if省略。
例如:- If it rains tomorrow, we will stay at home.(如果明天下雨,我们会待在家里。
