Activity2Fillintheblanks.省略(Ellipsis):英語(yǔ)中有時(shí)為了避免重復(fù),使語(yǔ)言簡(jiǎn)練緊湊,在不影響句子結(jié)構(gòu)和意義的前提下,往往省去一個(gè)或多個(gè)句子成分或詞語(yǔ),這種語(yǔ)法現(xiàn)象稱為省略。例如:It’stypicalthatmyjourneyisononeoftheoldestlines,aswellasoneofthedeepest(lines).

一、簡(jiǎn)單句中的省略在簡(jiǎn)單句中,可省略主語(yǔ)、謂語(yǔ)或謂語(yǔ)的一部分、賓語(yǔ)等,有時(shí)甚至同時(shí)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,如果后面的分句與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,以避免重復(fù)。例如:(1)Iarrivedheretoday,and(I)muststayhereoneortwoweeks.(省略主語(yǔ))(2)IaskedJohntogo,butshe(askedJohn)tostay.(省略謂語(yǔ)和賓語(yǔ))

(3)Knowingisonething,andbelieving(is)anotherthing.(省略系動(dòng)詞)(4)Inmyclass,boyslikesportswhilegirlsdonot(likesports).(省略謂語(yǔ)和賓語(yǔ))

(5)Myfatherlookedangry,andIcertainlywas(angry).(省略表語(yǔ))三、復(fù)合句中的省略1.定語(yǔ)從句中的省略在限制性定語(yǔ)從句中,可省略在從句中作賓語(yǔ)的關(guān)系代詞that、which、whom、who;但如果關(guān)系代詞作介詞的賓語(yǔ),且介詞置于關(guān)系代詞之前時(shí),則不可省略關(guān)系代詞。例如:(1)Thatisthefilm(which/that)wewatchedlastweek.(2)Tomisn’taman(whom/that/who)youcanbelievein.(3)Theathletetowhomyoutalkedisafamousrunner.

【注意】當(dāng)先行詞為theway且在從句中作狀語(yǔ)時(shí),從句用that或inwhich引導(dǎo),that或inwhich也常被省略。Weadmiredhimfortheway(inwhich/that)hefaceshisdifficulties.

2.狀語(yǔ)從句中的省略在狀語(yǔ)從句中,如從句的主語(yǔ)與主句的主語(yǔ)一致并且從句的謂語(yǔ)中又包含be動(dòng)詞時(shí),可以省略從句中的主語(yǔ)和be。另外,若狀語(yǔ)從句為it/there+be結(jié)構(gòu)時(shí),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.賓語(yǔ)從句中的省略(1)在賓語(yǔ)從句中,連詞that一般可以省略。(2)但在“介詞+形式賓語(yǔ)it+賓語(yǔ)從句”這一結(jié)構(gòu)中的that不可省。(3)賓語(yǔ)從句中包含that引導(dǎo)的兩個(gè)或兩個(gè)以上的并列賓語(yǔ)從句時(shí),通常只有第一個(gè)that可以省略。例如:①Idon’tbelieve(that)Mikehasjoinedthearmy.②YoumaydependonitthatIshallalwayshelpyou.③Lisatoldme(that)shewasillandthatshecouldn’tgotoschoolthenextday.【注意】有時(shí)可用so或not代替上文的內(nèi)容。例如:(1)Workhard.Ifnot(Ifyoudon’tworkhard),youwillfailintheexam.

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

【拓展】動(dòng)詞不定式中為了避免重復(fù),常省去前面出現(xiàn)的相同部分,而只保留不定式符號(hào)to;如果在省略的不定式結(jié)構(gòu)中含有系動(dòng)詞be或助動(dòng)詞have/havebeen時(shí),be/have/havebeen這些詞要保留。例如:(1)Iaskedmyfriendtohaveadrink,buthedidn’t(haveadrink).

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