Activity2Fillintheblanks.省略(Ellipsis):英语中有时为了避免重复,使语言简练紧凑,在不影响句子结构和意义的前提下,往往省去一个或多个句子成分或词语,这种语法现象称为省略。例如:It’stypicalthatmyjourneyisononeoftheoldestlines,aswellasoneofthedeepest(lines).

一、简单句中的省略在简单句中,可省略主语、谓语或谓语的一部分、宾语等,有时甚至同时省略若干成分。例如:(1)(You)Handmethebookoverthere.(2)(Is)Anybodyagainstthesuggestion?(3)—WhatdoyouthinkmadeDavidsohappy?—Passinghisdrivingtest(madehimhappy).

二、并列句中的省略在并列句中,如果后面的分句与前面的分句中有相同的成分,那么后面分句中相同部分常被省略,以避免重复。例如:(1)Iarrivedheretoday,and(I)muststayhereoneortwoweeks.(省略主语)(2)IaskedJohntogo,butshe(askedJohn)tostay.(省略谓语和宾语)

(3)Knowingisonething,andbelieving(is)anotherthing.(省略系动词)(4)Inmyclass,boyslikesportswhilegirlsdonot(likesports).(省略谓语和宾语)

(5)Myfatherlookedangry,andIcertainlywas(angry).(省略表语)三、复合句中的省略1.定语从句中的省略在限制性定语从句中,可省略在从句中作宾语的关系代词that、which、whom、who;但如果关系代词作介词的宾语,且介词置于关系代词之前时,则不可省略关系代词。例如:(1)Thatisthefilm(which/that)wewatchedlastweek.(2)Tomisn’taman(whom/that/who)youcanbelievein.(3)Theathletetowhomyoutalkedisafamousrunner.

【注意】当先行词为theway且在从句中作状语时,从句用that或inwhich引导,that或inwhich也常被省略。Weadmiredhimfortheway(inwhich/that)hefaceshisdifficulties.

2.状语从句中的省略在状语从句中,如从句的主语与主句的主语一致并且从句的谓语中又包含be动词时,可以省略从句中的主语和be。另外,若状语从句为it/there+be结构时,也可省略it/there+be。例如:(1)While(Iwas)inHangzhou,IpaidavisittotheWestLake.

(2)Theputerisofnouseunless(itis)repaired.

(3)Although(heis)stillyoung,heknowsalot.

(4)Handintheworktomorrowif(itis)possible.

3.宾语从句中的省略(1)在宾语从句中,连词that一般可以省略。(2)但在“介词+形式宾语it+宾语从句”这一结构中的that不可省。(3)宾语从句中包含that引导的两个或两个以上的并列宾语从句时,通常只有第一个that可以省略。例如:①Idon’tbelieve(that)Mikehasjoinedthearmy.②YoumaydependonitthatIshallalwayshelpyou.③Lisatoldme(that)shewasillandthatshecouldn’tgotoschoolthenextday.【注意】有时可用so或not代替上文的内容。例如:(1)Workhard.Ifnot(Ifyoudon’tworkhard),youwillfailintheexam.

(2)—DoyouthinkMr.Greenwillgiveushelp?—Ihopeso.(Ihopehewillgiveushelp.)

【拓展】动词不定式中为了避免重复,常省去前面出现的相同部分,而只保留不定式符号to;如果在省略的不定式结构中含有系动词be或助动词have/havebeen时,be/have/havebeen这些词要保留。例如:(1)Iaskedmyfriendtohaveadrink,buthedidn’t(haveadrink).

(2)—Areyouateachernow?—No,butIused(ateacher).
