There______nobusandwehadtowalkhome.

A.wasB.beingC.beD.tobe 答案:BA解题方法：先看选项，AC是谓语BD是非谓语第二个题目是并列句，所以前后是两个句子，and之前的句子缺的就是谓语动词，又由had决定了是过去时，所以用was第一道题目，前后两部分之间用逗号分开，所以不是并列句，所以前一部分是后一部分的状语，也就不是句子，所以选非谓语，用being2．Thegirl______inaredcoatisMary.

Thegirlis______Marynow.

A.dressedB.dressingC.dressD.todress 答案:AB

解题方法：先看题目，第一道题目中有一个动词is,所以缺少的是非谓语动词，应该从ABD中选过去分词词bedressedin,所以选用dressed.第二道题目缺少谓语动词，前面有is算be应该选dressing构成进行时（谓语动词）解决学习问题：目标对应的活动（目标的问题化分解）：考点一了解非谓语动词的分类教师提问：刚刚我们已经回顾了如果区分谓语与非谓语，那么，你知道非谓语包含哪些分类吗？1、定义：在英语中，不作句子谓语，而具有除谓语外其他语法功能的动词，叫做非谓语动词。2、分类：Reading

It+be+awasteoftimedoing...做……是浪费时间的Itis/wasnogood/usedoing...做……是无益/用的Itisworthdoing...做...值得的例：ItisawasteoftimetryingtoarguewithSherlock.和夏洛克争辩是浪费时间的。Isitanygoodtryingtoexplain?努力解释有任何好处吗?ItisworthreadingthebookHarryPotter.《哈利波特》这本书值得一读。先让学生观察例句，再让学生理解动词ing作宾语的用法。二、动词ing形式作宾语动名词可以作某些动词、动词短语及介词的宾语。如:Wouldyoumindturningdownyourradioalittle,please?请把你的收音机音量调小一点儿,好吗?Icrossedthestreettoavoidmeetinghim.我横穿街道以便避开他。※知识补充：习惯上接动名词作宾语的动词:admit承认advise建议stand忍受permit允许 forbid禁止 appreciate感激avoid避免consider考虑delay推迟deny否认 enjoy喜欢 escape逃脱excuse原谅 finish完成forgive原谅imagine设想;想象 keep保持 mind介意miss错过practice练习risk冒险suggest建议resist抵制 dislike不喜欢fancy设想;想象2.接动名词作宾语的短语:putoff推迟 insiston坚持 feellike想要 depend/relyon依靠objectto反对 leadto导致 succeedin成功做…… beworth值得devote...to...献身于……lookforwardto期盼owingto归因于giveup放弃payattentionto注意stickto坚持contribute...to致力于applyoneselfto致力于getdownto开始认真干……be/getusedto习惯于befondof喜欢begoodat擅长于what/howabout...……怎么样bebusy(in)doing忙于can’thelpdoing禁不住;忍不住spend...(in)doingsth花费……做某事havedifficulty/trouble(in)doing做……有困难下列动词及动词短语后跟动词ing和不定式都可以，但意义不同。动词接动词ing作宾语接不定式作宾语remember记得曾做过某事记得要做某事forget忘记曾做过某事忘记要做某事try尝试做某事努力做某事regret对做过的事表示后悔对要做的事表示遗憾mean意味着做某事企图(打算)做某事can'thelp禁不住做某事不能帮助做某事goon继续做未完成的事做完一件事后，接着做另一件事stop中断正在做的事中断正在做的事，去做别的事attempt,begin,start,prefer,intend等后接动词ing或不定式作宾语均可,意义没有区别。【例题分析】Ican’tstand(work)withJaneinthesameoffice.Shejustrefusestostoptalkingwhilesheworks.working〖解析〗standdoingsth.容忍做某事；句意为：我不能容忍跟珍妮在一个办公室工作,她工作时总是喋喋不休。It

buying▲动词ing形式作定语和表语观察下列从reading中选取的句子，注意分析Ving形式作的句子成分。Noonewaseverboredwatchinghimhissubtleactingmadeeverythingentertaining.Hegrewmoreandmorepopularashischarmingcharacter,thelittletramp,becameknownthroughouttheworld.Theactingissoconvincingthatitmakesmakesyoubelievethatitisoneofthebestmealshehasevertasted.自我总结：划线部分分别作定语;定语;表语;Ving形式作定语Ving形式包括现在分词与动名词，他们的形式相同，都可作定语，但连着还是有以下区别的。现在分词作定语时，它和被修饰的词之间有一种逻辑上的主谓关系，即被修饰的词执行现在分词所表示的的这个动作，相当于一个定语从句。如：awaitingman=amanwhoiswaitingasleepingchild=achildwhoissleeping动名词作定语，与被修饰词之间没有这种关系，它仅表示一种用途，意为“作...用”。如：aswimmingpool；thereadingroom；asleepingcar=acarforsleeping（卧铺车厢）（3）体验：Ving是作动名词还是现在分词？Wemustimproveourworkingmethod.(动名词)我们必须改进工作方法。Theysetupanoperatingtableinasmalltemple.(动名词)他们将手术台设在一座小庙里。Chinaisadevelopingcountry.(现在分词)中国是发展中国家。Thestudentmakingtheexperimentisourmonitor.(现在分词)正在做实验的那个学生是我们的班长。（4）注意：现在分词和现在分词短语都可作定语，单个现在分词一般作前置定语，现在分词短语则作后置定语,相当于一个定语从句。1、developingcountry单个现在分词一般作前置定语；特殊情况：修饰不定代词时，现在分词放在其后————somethingdeveloping2、themanvisitingJapan=themanwhoisvisitingJapan现在分词短语则作后置定语；Ving形式作表语动名词与现在分词作表语的区别：动名词作表语表示一般性，经常性的动作。HisjobisteachingEnglish.动名词作表语表示主语的内容，可以把主语和表语交换。Ourjobisplayingallkindsofmusic.Seeingisbelieving.（眼见为实）（3）现在分词作表语说明主语的性质，特征，此时主语和表语不可以交换位置。常用来作表语的现在分词有astonishing,amusing,confusing,disappointing,boring,encouraging,inspiring,moving,tiring,interesting,surprising等。Themusicissoexciting.Thebookissointeresting.Ving形式作宾语补足语动名词不作宾语补足语；现在分词作宾语补足语主要用在某些动词如see,hear,notice,watch,keep,find,get,have,feel等后，与一个名词或代词构成复合宾语。这时句子的宾语和Ving之间存在逻辑上的主谓关系，并且Ving表示宾语正在进行的动作。如：Isawhimopeningthewindow.Ving形式和不定式（todo）作宾语补足语的区别：现在分词表示动作正在进行，而不定式表示动作发生了，即动作的全过程结束了。对比：Isawhimopeningthewindow.Isawhimopenthewindow.注意：在see，hear，watch，feel等感官动词后，跟省略了to的不定式做宾补，但在被动语态中，应加上“to”。试一下把“Isawhimopenthewindow.”改被动语态：Hewasseentoopenthewindow(byme).【例题分析】1.Aliensaidthathistripwas___________(interest).interesting2.It'snouse__________(argue)withhim.Youmightaswell________(argue)withastonewall.arguing,argue3.Theoldman's_________(take)pityonthesnakeledtohisowndeath.takingItis________(shock)thatsomeinvestmentbanksevenjudgecandidatesbywhethertheywearbrownshoes.shockingWithsomanypeople________(look)athim,hefeltverynervous.looking▲动词ing形式作状语一、Ving形式作状语的句法功能(1)作时间状语(相当于一个时间状语从句)Hearingtheknockonthedoor,theystoppedtalking.=Whentheyheardtheknockonthedoor,theystoppedtalking.听到有人在敲门,他们停止了谈话。作原因状语(相当于一个原因状语从句)Beingill,hedidn’tgotoschoolyesterday.=Ashewasill,hedidn’tgotoschoolyesterday.因为生病了,昨天他没去上学。作伴随状语(动词ing形式表示的动作与谓语动词表示的动作同时发生,相当于并列谓语)Theystoodthere,waitingforthebus.=Theystoodthereandwaitedforthebus.他们站在那儿等公共汽车。(4)作方式状语(相当于一个并列句)Hediedagloriousdeath,fightingtheenemyforthepeople.=Hediedagloriousdeath,andhefoughttheenemyforthepeople.他为了群众同敌人搏斗,光荣牺牲了。(5)作结果状语Herhusbanddiedlastyear,leavingherwiththreechildren.她的丈夫去年去世了,撇下她和三个孩子。二、使用动词ing作状语应注意的问题(1)动词ing作状语，其逻辑主语要与句子主语保持一致，否则，要用独立主格结构。Ridingahorseordrivingacar,youshouldlearntocontrolit.无论是骑马还是驾车，你都应该学会控制它。Iwaitingforthebus,abirdfellonmyhead我等汽车时，一只鸟落到我头上。独立成分作状语有些分词短语，其形式的选择不受上下文的影响，称作独立成分。常见的有：generallyspeaking总的来说；judgingfrom/by根据……判断；speakingof说到……；talkingof谈到……；franklyspeaking坦率地说；allowingfor考虑到。①Judgingbyhisface,hewasangry．从他的脸色上看，他很生气。②Theprojectwilltakeabout8months,allowingfordelayscausedbytherainyseason.考虑到雨季的耽误，这项工程大约需要8个月。③Franklyspeaking，thecarisnotworthbuying.坦率地说，这部车不值得买。注意：这时句子主语与其无任何语法关系。【例题分析】Ilikestayinguplate________(watch)TV,surfingtheInternetordoingsomethingI'mfondof.分析：watching逻辑主语I与watch之间为主动关系，表示伴随状态，故填现在分词watching。MorehighwayshavebeenbuiltinChina,________(make)itmucheasierforpeopletotravelfromoneplacetoanother.making________(see)thepolice,thethievesranaway.Seeing教师提问：动词ing的结构形式只有Ving吗？有没有别的形式？观察所给例句，引导学生总结各动词ing结构的形式表达。考点三、动词ing的结构形式；语态形式主动语态被动语态一般式doingbeingdone完成式havingdonehavingbeendone1、动词ing形式的一般式(doing),可以表示没有时间先后顺序的动作；Iwishyouwouldquitplaining.我希望你不再抱怨。(一般性动作)Chattingwitheachother,weenjoyedourdinner.我们边吃边聊。(与谓语同时发生)2、动词ing形式的完成式(havingdone),表示动作发生在谓语动词之前。Havingfinishedwork,shegotreadytogoshopping.完成工作后，她准备去购物。Havingbeenillfortwoweeks,shefeltratherweak.由于病了两周，她感到身体很虚弱。3、动词ing形式的否定式：not+动词ingNotknowingthis,hedidn’te.他不知道这件事，所以没来。Nothavingmadefullpreparations,weputoffthesportsmeeting.因为没有做好充分的准备，我们把运动会延期了。【查漏补缺】单句语法填空。1.Thenationalparkhasalargecollectionofwildlife,_________(range)frombutterfliestoelephants.2.Thehospitalhasrecentlyobtainednewmedicalequipment,__________(allow)morepatientstobetreated.3.ManyChinesebrands,__________(develop)theirreputationsovercenturies,arefacingnewchallengesfromthemodernmarket.Fastfoodisfulloffatandsalt;by
