GoforGrammar

省略句(EllipticalSentence)是英语中一种常用的语言现象,它通过省略句子中的某些重复的或多余的成分,使句子简洁明快,重点突出。

省略前提:主谓宾,定状表,如有重复可删掉。

省略原则:词语省略后,不致令人费解。

一、简单句中的省略1.省略主语。

(1)祈使句中的主语通常被省略。

(You)Openthedoor,please.请打开门。

(2)其他省略主语多限于现成的说法。

(I)Thankyouforyourhelp.谢谢你的帮助。

2.省略谓语或谓语的一部分。

(Is)Anybodyhere有人吗

3.省略宾语。

—DoyouknowMrWhite

—Idon’tknow(him).

——你认识怀特先生吗

——我不认识他。

4.省略主语和谓语,或主语和谓语的一部分。

(Thereis)Nosmoking.禁止吸烟。

(Youcome)Thiswayplease.请这边走。

GoforGrammar

5.省略表语

Areyouthirsty

Yes,Iam(thirsty).你渴吗？渴

Hisbrotherisn'tlazy.Norishissister(lazy).他的哥哥和姐姐都不懒

二、并列复合句中的省略

两个并列分句中，后一分句常省略与前一分句中相同的部分。

Mikesaidthathewouldcometoschooltoseemethenextday,buthedidn't(cometoschooltoseemethenextday).迈克说他第二天会来学校看我，但他没有（第二天来学校看我）

Lin'sfatherwasnotathome,buthismotherwas(athome).林的父亲不在家，但他的母亲（在家）。

Shewaspoorbut(shewas)honest.她很穷，但（她）诚实。

三、动词不定式的省略

1.在expect,forget,hope,intend,love,mean,prefer,refuse,wish等动词后,在语义明确情况下,可只保留不定式符号to。

Iaskedhertogototheconcertwithme,butshedidn’twantto(gowithme).

我让她和我一起去听音乐会,但是她不想去。

—WillyouhelpmewithmyEnglish

—Yes,I’dliketo(helpyouwithyourEnglish).——你帮我学英语好吗——好的,我乐意帮你。

2.不定式在happy,glad,eager,ready,willing等形容词后面作状语时,可以省略,但要保留不定式符号to。

—Willyoujoinusinthegame—I’dbegladto(joinyouinthegame).

——你和我们一起玩游戏好吗——我很高兴和你们一起玩游戏。

GoforGrammar

注意:如果不定式中含有be或havedone,要保留be或have。

—Areyouateacher——你是教师吗

—No,Iusedtobe.——不是,我以前是。

四、定语从句中作宾语的关系代词的省略

1.that,which,who,whom在限制性定语从句中作宾语时可省略。

Whereisthebook(that,which)youborrowedfromthelibrarylastweek

你上周从图书室里借的书在哪里

2.先行词是theway时,后面的定语从句可省略that或inwhich。

Inmyopinion,theway(that,inwhich)hedidtheexperimentwasnotright.

我认为他做实验的方式不正确。

五、状语从句中的省略

1.当状语从句的主语和主句的主语一致,且谓语中含有be时,可以省略从句的主语和be,而保留后面的名词、形容词、介词短语、分词或动词不定式。

Unless(youare)askedtospeak,youshouldremainsilentattheconference.

如果没有人请你讲话,你应该在会上保持沉默。

Thiskindofmedicinehasnosideeffectsif(itis)takenaccordingtotheinstructions.

如果按照说明书服用,这种药没有副作用。

GoforGrammar

2.在“when(或if,where,wherever,whenever,assoonas,asfastas,than等)+possible/necessary等”句式中,可理解为中间省略了itis(或was)。

Healwayscomestohelpmewhenever(itis)possible.

只要有可能,他总是来帮我。

Youcantakeouttheinformationfromthecomputerwhen(itis)necessary.

有必要时你可以从电脑里把信息提取出来。

六、虚拟语气的省略

(1)虚拟条件句常省略if，将were，had，should提前构成部分倒装。

(2)在一坚持(insist)，二命令(order，command)，三建议(suggest，propose，advise)，四要求(demand，require，request，desire)等后的宾语从句中，含这些词的派生词的其他主语从句、同位语从句、表语从句，以及Itisstrange/natural/necessary/importantthat...从句中常省略should。
