英语新课标（WY）·八年级下册单元语法聚焦十语法点击宾语从句的时态及否定转移在前两个模块中，我们学习了宾语从句的引导词和语序问题，本模块我们学习宾语从句的时态及否定转移问题。一、宾语从句的时态1．当主句的谓语动词是一般现在时时，其宾语从句的时态应根据实际情况而定。例如：Shesays(that)sheworksfromMondaytoFriday.她说她从周一至周五上班。(从句是一般现在时)Shesays(that)shewillleaveamessageonhisdesk.她说她将在他书桌上留个便条。(从句是一般将来时)Shesays(that)shehasneverbeentoMountTai.她说她从来没有去过泰山。(从句是现在完成时)2．当主句的谓语动词是一般过去时时，其宾语从句的时态一般使用相应的过去时态。例如：Hesaidtherewerenoclassesyesterdayafternoon.他说昨天下午没有课。(从句是一般过去时)Hesaid(that)hewasgoingtotakecareofthebaby.他说他会去照看那个婴儿。(从句是过去将来时)Hesaid(that)theywerehavingameetingatthattime.他说那时他们正在开会。(从句是过去进行时)单元语法聚焦十注意：当宾语从句表示客观真理、自然现象、科学原理时，其时态不受主句谓语动词的限制，仍用一般现在时。例如：Theteachertoldus(that)nothingisdifficultifweputourheartsintoit.老师告诉我们世上无难事，只怕有心人。Hesaidthatlighttravelsmuchfasterthansound.他说光比声音传播得快。二、宾语从句的否定转移当主句的主语是第一人称I/we，谓语动词是think,believe,suppose等时，如果其后的that宾语从句表示否定意义，not应否定主句谓语。例如：单元语法聚焦十Idon'tthinkheisright.我认为他是不对的。Idon'tbelievehewillcome.我相信他不会来。单元语法聚焦十实战演练Ⅰ.单项填空()1.[2014·南充]—Iwanttoknow________themachine.—It'seasy.Letmeshowyou.A．whatIcanuseB．howIcanuseC.whatcanIuseitD．howcanIuseit()2.I'msure________hewillbehereontime.A.ifB.thatC.whetherD．when单元语法聚焦十()3.Canyoutellme________？A.what'sthematterwithhimB.whatthematterwithhimisC.whathappenedwithhimD．whatwithhimhappened()4.[2013·莱芜]Father'sDayiscoming.I'mthinkingabout________．A．whatpresentIgavehimB．wherewehadabigmealC．howIwillgivehimasurpriseD．ifIplannedapartyforhim单元语法聚焦十()5.[2014·黔西南]Couldyoutellme________？—YoucantaketheNo.1bus.A.howcanwegettoXingyiAirportB．howwecangettoXingyiAirportC．howdowegettoXingyiAirportD．howwegottoXingyiAirport()6.Brucesays________hecancomeat9：00tomorrow.A.whenB.whatC.thatD.whattime单元语法聚焦十()7.Dave,couldyouteachme________tosearchtheInternet?A.thatB.howC.whenD．why()8.Couldyoutellme________？A.whereisthenearestpostofficeB.wherethenearestpostofficewasC.wherethenearestpostofficeisD.wherewasthenearestpostoffice单元语法聚焦十()9.Hewantstoknow________tolearnChinesewell.A.ifB.whenC.howD.that()10.[2013·贺州]Canyoutellme________？A．howmuchistheredsweaterB．howmuchtheredsweaterisC．what'sthepriceoftheredsweaterD．howmanytheredsweateris[答案]1—5BBACB6—10CBCCB单元语法聚焦十Ⅱ.用所给词的适当形式填空1．Ihearthatshe_________(be)backsoon.2．Myfathersaidhe_________(can't)findhiscarkeythismorning.3．WeknowthatTaiwan_____(be)inthesoutheastofChina.4．Iwanttoknowifhe_________(give)usatalkthisafternoon.5．Myunclewasnotsureifhe___________(have)enoughmoneytobuyanewhousethenextyear.willbecouldn’tiswillgivewouldhave单元语法聚焦十6．Lisaaskedwhetherlight________(travel)fasterthansound.7．Heaskedthepolicehowmanypeople_______(die)intheaccident.8．Doyouknowwhenthetrain___________________(leave)tomorrow?travelsdiedwillleave/isleaving单元语法聚焦十
