There-be-句型的非谓语动词形式

小议Therebe句型的非谓语动词形式陕西省丹凤中学蔡进军726200英语学习者都知道Therebe句型表某时或某地存在某物或某事件。也知道这个句型有不同的时态形式。另外，我们在解题时还会遇到与下面同类的试题。1.Today,Ithinkwehavediscussedalotaboutproblem.Iexpect_____tobenoargumentaboutthis.A.themB.thereC.itD.you2.Noonehadtoldmeabout______ameetingthefollowingday.A.theretobeB.therebeingC.therewouldbeD.therewas3.ManypeopleinChinahaveneverdreamtof______achanceforthemtolearntodriveafterthereretirement.A.beingB.thereisC.theretobeD.therebeing很显然，这类试题旨在考察存在句的谓语动词和非谓语动词形式。重点在考察Therebeing和Theretobe这两种形式。下面就围绕该句型的非谓语动词形式做谈几点体会。首先，要搞清谓语动词与非谓语语动词的有关内容。1.谓语动词在句中做谓语，有时态和语态特征。例：do有do/does/did/(am,is,are,was,weredoing)/have/hasdone/will/shalldo/have/hasbeendone/doing等时态和以bedone为主体的语态形式。而非谓语动词不做谓语，一般做定语或状语，有doing/done/todo等形式。2.理清一对关系：有非谓语动词，就一定有其依附的谓语动词。3.英语中，以一个句号为单位构成一个句子。当一个句子中已有谓语动词，在没有并列连词和从属连词的前提下，再就不能有谓语动词出现，但可以有非谓语动词出现。Allthetask_____aheadoftime,theydecidedtogoonholidayforaweek.A.hadbeenfinished.B.werefinishedC.havingbeenfinishedD.beenfinished解析：题干中只有一个句号，表明是一个句子，逗号后无并列连词或从属连词，且decidedtogo已为谓语动词，故空上应为一非谓语动词,A/B选项均为谓语动词，应排除。D选项是与have/has/had构成完成时态的被动态的，也应排除。故答案选C.其次，therebe句型有谓语动词与非谓语动词，如thereis/are/was/were/willbe/willhavebeen等谓语动词形式，还有非谓语动词形式theretobe和therebeing.下面重点谈两种非谓语动词形式的区别：1.动词后用theretobe。2.介词后用therebeing.但for后用theretobe.故开篇3道单选题分别选择答案：BBC.下面重点谈一谈theretobe与therebeing使用时的几种情况：1.两种结构都作介词宾语。若介词为for，只用theretobe。Itwasunusualfortheretobesofewpeopleinthestreets.Johnwasrelyingontherebeinganotheropportunit.也可用在不及物动词+for后。Theyplannedfortheretobeanothermeeting.若介词不是for，而是其他，则要用therebeing结构。2.作动词宾语时，通常有theretobe结构。能这样用的及物动词有expect,mean,intend,want,like,prefer,hate等。Membersliketheretobeplentyofchoice.3.therebeing结构还能用作名词性分句和状语分句。Therebeingabusstopsonearthehouseisagreatadvantage.Therehavingbeennorain,thegroundwasdry.巩固性练习：用theretobe和therebeing填空。1.Pepoledon’twantanotherwar.2.There’snowsomehopeofasettlementofthedispute.3.Theyaskedforanothermeeting.4.Johnaskedaboutanothermeeting.5.Johnintendedameetingafterwards.6.It’sessentialformorehousesbuiltnearyear.7.nofurtherbusiness,theChairmanclosedthemeeting.8.Johnplannedonanothermeeting.9.Pepolehatequeueseverywhere.10.WhatJohnwaswaitingforwasforcompletesilence.
