状语从句中的省略用法

英语中的省略

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。

英语中状语从句的省略规则

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

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 18—storied building ,when ______, will shut out the sun lighting up the rooms in my house.A completed B. to be completed C. completing D. have completed (A)17. 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。

省略在状语从句中的运用

省略在状语从句中的运用
1.当主句的主语与状语从句的主语相同，且从句中的谓语是动词的情况下，可以省略状语从句中的主语和谓语。

例如：
- 原句：When I go to school, I always take the bus.
- 省略主语：When going to school, I always take the bus.
- 省略主语和谓语：Going to school, I always take the bus.
2.当主句的主语与状语从句的主语不同，且从句中的谓语是动词的情况下，可以省略状语从句中的主语，并保留谓语。

例如：
- 原句：When John goes to school, he always takes the bus.
- 省略主语：When going to school, he always takes the bus.
3. 当状语从句中的谓语是 be 动词时，可以省略主语和谓语，并保留 be 动词形式。

例如：
- 原句：When it is raining, I stay at home.
- 省略主语和谓语：When raining, I stay at home.
需要注意的是，省略状语从句的主语和谓语部分并不是必须的，根据语境和需要进行判断和运用。

此外，需要注意省略后的句子是否仍然能够保持语义上的完整和准确。

高中英语语法之省略

高中英语语法之省略英语中省略现象较为普遍，对省略的考查已成为高考中的热点。

句子成分的省略，可分为以下几种情况：为了使话说得简明扼要，英语句子中某个单词、短语甚至从句或主句都能够省去。

Ⅰ、状语从句中的省略用法一、如果从句的主语和主句的主语一致，且从句的谓语含有be动词的某种形式（am/is/are/was/were），可同时省略从句的主语和be动词的某种形式。

1、when，while引导的时间状语从句e.g. Do be careful when (you are) crossing the street.When/While (I was) on my way to work, I met her.2、if，unless，once引导的条件状语从句e.g. If (it is) properly treated, waste will do no harm to the environment.I’ll not go to the party unless (I am) invited.Once (you are) caught stealing in a supermarket, you will be punished.3、though，although，whether，no matter whether/what/how/who等引导的让步状语从句e.g. He was happy, though/although (he was) poor.Whether (she is) sick or well, she is always cheerful.No matter how/However hard the task (is), we must fulfill it in time.（注：从句的主语和主句的主语不一致时，只省略从句中的be动词形式）4、as if，as though引导的方式状语从句e.g. He rubbed his eyes and yawned as if/though (he was) waking up after along sleep.He stood up as if/though (he wanted) to leave.（as if/though + to do表示一个将来的动作）二、than，as引导的比较状语从句中的省略用法：当不同的主语实行比较时，一般省略从句中的谓语；当从句中的主语与谓语（be动词除外）和主句中的主语与谓语相同时，通常省略从句中的主语和谓语，只保留比较部分。

状语从句的省略与强调句型

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。
