高中英语省略句及练习讲解
高中英语省略句莎士比亚曾经说过：Brevity is the soul of wit. （言以简为贵）。
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可以省去。
这种省去句子某些成分而保持句子意思不变的现象，称为省略（ellipsis）。
一、省略的目的省略多见于非正式的文体，尤其在对话中，省略是一种十分普遍的现象。
英语中的省略一般说来有三个目的：A．避免重复，减少累赘。
省略的主要目的是避免重复，去掉不必要的累赘和繁琐。
Mike said that he would come to school to see me the next day, but he didn't come to school to see me the next day. 迈克说他第二天要来学校看我，但是第二天他并没有来学校看我。
-- Mike said that he would come to school to see me the next day, but he didn't. 迈克说他第二天要来学校看我，但是他并没有来。
(省掉最后九个词，句子简洁多了)— What did he want yesterday 他昨天要了什么？— An apple. 一个苹果。
（如果回答时说出全文“He wanted an apple yesterday”，便显得别扭，不自然）B．连接紧密，结构紧凑。
省略也是使上下文紧密连接的一种修辞手段。
John was the winner in 1994 and Bob in 1998. 约翰是1994年的获胜者，鲍勃是1998年的获胜者。
（Bob后省略了was the winner，句子结构显得比较紧凑）In some places we stopped in tents for the night, in other places in caves. 我们在有些地方住在帐篷里过夜，在有些地方住在山洞里。

省略
省略
定义
为了避免重复，突出关键词语，并使上下文紧密连接， 在句子中有时就省去了一个或几个句子成分。这种语法手 段就称为省略。省略是重要的修辞原则，因此，只要不损 害语法结构，不产生歧义，能省略的就应省略。
英语省略句
高考英语考点-省略句省略句是高考考查的语法重点，又是学习的难点。
在英语中，为了使句子简洁明快，突出重点，常用"省略句"，只要不影响句意的表达，能省略的成分尽可能省略。
省略现象随处可见,大致可分为以下几种情况。
一、句子成分的省略1. 省略主语。
如:Haven't seen you for ages!好久不见了!2.省略谓语。
如：(Is there) Anything you want? 你要什么东西吗?(Does) Anybody need help? 有人要帮忙吗?3. 省略宾语。
如：I don't know (where he is ). 我不知道。
4.省略主语和谓语（或谓语的一部分），只剩下表语、宾语、状语或其它成分。
如：(I'm) Afraid I can't come. 恐怕我不能来了。
(Have you) Got any ink? 你有墨水吗?【高考链接】－It’s a long time since I saw my sister.（2007全国卷1）－_________her this weekend?A. W hy not visitB. Why not to visitC. Why not visitingD. Why don’t visit解析：答案为A。
本题考察省略结构，这里why not visit =Why didn’t you visit ，这种既注重基础又兼顾生活交际的试题，其实多数学生感觉很容易能得出正确的A答案。
二、复合句的省略1.在含有状语从句的复合句中由when，while，as, once，whenever引导的时间状语从句；或由if，unless引导的条件状语从句；由though，although，even if ，even though引导的让步状语从句；由as though，as if，as引导的方式状语从句；由because引导的原因状语从句；由wherever引导的地点状语从句，若从句的主句是it或与主句的主语相同，且在谓语中含有be时，常省略从句的主语和be。

省略句一、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：当不同的主语进行比较时，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。
e.g. He is taller than his brother (is).I have as much as confidence in you as (I have confidence) in him.三、以if从句为代表的状语从句中的特殊省略用法：通常省略了it is，that is，there is/are。
e.g. If (it is) possible/necessary, this old temple will be rebuilt.If (that is) so, I will call you back at 5:00 pm.There are only a few books in our school library, if (there are) any.Ⅱ、定语从句中的省略用法关系词的省略关系代词that，which，whom等在限制性定语从句中充当宾语且不位于介词之后时，可以省略；in which或that在先行词way后作方式状语从句时可省略。
e.g. The man (that/who/whom) you visited last night is my grandpa.I don’t like the way (in which/that) you treat the girl.Ⅲ、虚拟语气中if及should的省略1、当条件状语从句中有were，had，should等时省略if，把它们提至句首，形成倒装句。
e.g. If I were a teacher, I would be strict with my students.= Were I a teacher, I would be strict with my students.2、Suggest，insist，order，require等表示建议、要求、命令的动词后接的名词性从句中，谓语动词常用“should+动词原形”，should可以省略。
e.g. The doctor suggested that he (should) try to lose weight.Ⅳ、不定式符号to的省略1、感官动词see，hear，feel，watch等和使役动词have，make，let等后接不定式作宾语时，不定式省略to。
2、do nothing but，can’t help but等结构常接省略to的不定式。
e.g. We didn’t do anything but stay at home watching TV yesterday.Hearing the news, she couldn’t help but cry.3、在特定语境中为了避免重复，当不定式再次出现时，在want，wish，hope，try，plan，like，love，hate后往往只保留to，而省略后面的动词。
但不定式后有be，have时，也保留be和have。
e.g. My parents encouraged me to go to college, but I didn’t want to.Ⅴ、So和not的替代性省略用于避免重复前面所说过的内容，替代词so/not替代肯定或否定的名词性从句。
可与believe，do，expect，fear，guess，hope，say，speak，suppose，think，I’m afraid等连用e.g. – Do you suppose he is going to attend the meeting? – I suppose not.Ⅵ、日常交际中的省略在情景会话中，答语常常省略不会引起歧义的主语、谓语或宾语部分，而只保留对方希望了解的内容。
在复合句或并列句中，也有省略主、谓、宾的情况。
