第19讲 句子种类（学生版不带答案）

第份初中语法讲义句子种类年月日 第19章句子的种类英语中的句子根据其使用目的可以分为陈述句、疑问句、祈使句和感叹句四种；按其语法结构（即句子的形式）可以分为简单句、并列句和复合句。本章对陈述句、祈使句、感叹句作了详实说明。疑问句所包含的内容较多，将在下一章详加叙述。典型例句：（陈述句）Thisisadog.（这是一只狗。）典型例句：（疑问句）Isthisadog?（这是一只狗吗？）典型例句：（祈使句）Openyoureyes!（睁开你的眼睛！）典型例句：（感叹句）Whatabeautifulbuildingitis!（这是座多么漂亮的大楼啊！）典型例句：（简单句）Iamstudying.（我在学习。）典型例句：（并列句）IwasborninasmallvillageandIliedtherefornearlytenyears.（我出生在一个小村庄，并在那里生活了近十年。）典型例句：（复合句）AssoonasIgetthere,I’llcallyou.（我一到那儿，就给你打电话。）1.陈述句用以陈述事实或观点的句子叫做陈述句，陈述句包括肯定结构和否定结构。陈述句通常用降调，句末用句号“.”。肯定句：WeliveinBeijing.（我们住在北京。）否定句：Wedon’tliveinBeijing.（我们不住在北京。）陈述句是英语中最常用的句子，本书详细地讲述了各种时态的陈述句（参见（第9章动词概说—第15章动词的完成时））。1.肯定结构的陈述句Wecanusemobilephonestosendshortmessages.（我们可以用手机发送短信。）Theyarelookingforwardtoseeingthefilm.（他们期待着看这部电影。）Igotaletterfrommyparentslastweek.（上周我收到了父母的来信。）Tomwasveryproudofhismodelplane.（汤姆为他的飞机模型而感到自豪。）Iwasafraidtomakefriendswithanyone.（我不敢和任何人交朋友。）Hejumpedintotheriverandsavedtheboy.（他跳进河中，救了男孩一命。）Shehaslosttouchwithmostofherfriendsfromprimaryschool.（她与小学时的大部分朋友已经失去了联系。）TheywillplanttreesonSaturday.（周六他们将要去植树。）Wearegoingtovisithimnextweek.（我们打算下周去拜访他。）2.否定结构的陈述句Iamnotastudent.（我不是学生。）Hecan’tspeakEnglish.（他不会说英语。）Idon’tknowhim.（我不认识他。）（1）be动词的否定句句型：主语+be动词+not+……Iwasn’tgoodatEnglish.（我英语不好。）Heisn’tmycousin.（他不是我表弟。）I’mnotfondofthegame.（我不喜欢这个游戏。）A.进行时和被动语态（指现在时、过去时、进行时的被动语态）都有be动词，所以它们的否定句与be动词的否定句同形。（参见（第16章被动语态））Theyaren’tcleaningtheroom.（他们没在打扫房间。）（本句为现在进行时）Hewasnotelectedasthemonitor.（他没有被选为班长。）（本句为过去时的被动语态）B.将来时（will，shall）、完成时及情态动词被动语态的否定句与be动词的否定句不同形。（⚪）Theywillnotbesenttothefront.（他们将不会被送到前线。）（×）Theywillbenotsenttothefront.（⚪）Theworkhasnotbeenfinished.（这项工作还没有完成。）（×）Theworkhasbeennotfinished.补充：否定式的缩略形式isnot→isn’tarenot→aren’twasnot→wasn’twerenot→weren’tdonot→don’tdoesnot→doesn’tdidnot→didn’tcannot→can’twillnot→won’tmustnot→mustn’thavenot→haven’thasnot→hasn’thadnot→hadn’tamnot→I’mnot（amnot无缩写形式，应为I’mnot形式）（2）情态动词的否定句句型：主语+情态动词+not+动词原形+……Ican’tdoitbymyself.（我自己做不了这件事。）Youmustn’ttakethebooksout.（你（们）一定不能把书拿出去。）Youmustnotgotherealone.（你一定不要单独去那里。）注意：must作“必须”讲时，它的否定形式mustn’t/mustnot并不是“不必要”的意思，而是“不许（表示禁止）”的意思。（3）完成时的否定句句型：主语+have/has/had+not+动词的过去分词+……Ihaven’tfinishedreadingthebookyet.（这本书我还没看完。）Hehasn’thadhisbreakfastyet.（他还没吃早饭呢。）Hehadn’tdesignedanyplanbytheendoflastmonth.（截至上个月末，他还没想出任何设计方案。）（4）行为动词的否定句句型：主语+do/does/did+not+动词原形+……（参见（第11章动词的一般现在时）和（第12章动词的一般过去时））Theydon’tliveinShanghai.（他们不住在上海。）Hedoesn’tdohishomeworkeveryday.（他不是每天都做作业。）Theydidn’thavetheclassmeetingyesterday.（他们昨天没开班会。）Shedidn’tpasstheEnglishexamyesterday.（她昨天没有通过英语考试。）（5）否定结构应注意事项A.使用not表示否定。（1）not表示部分否定。含有not的句子，如果使用了very，always以及不定代词all，both，every及every的复合词等，则表示部分否定。（其余的部分否定结构请参见（第2章代词）中的不定代词部分）Idon’tplayfootballverywell.（我足球踢得不是很好。）Itisn’talwayshothereinsummer.（这里夏天不一定总是很热。）Allofusarenotstudents.（我们并非都是学生。）比较：表示全部否定Idon’tplayfootballwell.（我足球踢得不好。）Itisn’thothereinsummer.（这里夏天不热。）Noneofusarestudents.（我们都不是学生。）（2）not的固定搭配表示否定。not...atall一点也不……I’mnottiredatall.（我一点也不累。）（语气强烈）Idon’tlikeitatall.（我一点也不喜欢它。）not...anylonger，not...anymore再也不……Idon’tlivehereanylonger.=Inolongerlivehere.（我再也不在这儿住了。）注意：在含有宾语从句的主从复合句中，当主句的谓语动词是think（认为），believe（相信）等词时，宾语从句谓语动词的否定，习惯上要前移到主句的谓语动词前。Idon’tthinkyouareright.（我认为你不对。）Wedon’tbelievehe’llwin.（我们相信他不会赢。）Icannotseeyouanymore.=Icannolongerseeyou.（我再也见不到你了。）B.使用not以外的否定词表示否定。用no表示：no+名词=notany...一点也不……补充：在no和名词之间不能加冠词、指示代词、物主代词以及much，many，any，some等限定词。Thereisnowind=Thereisnotanywind.（一点风都没有。）never决不（语气比not强烈）I’llneverforgetyou.（我决不会忘记你。）few/little几乎没有比较：few和little的区别few修饰可数名词复数，little修饰不可数名词。Hehasfewfriends.（他几乎没有朋友。）Ihavelittlemoney.（我几乎没有钱。）Thereislittlewaterintheglass.（杯子里几乎没有水。）noone（=nobody）无人Nooneknowstheanswer.=Nobodyknowstheanswer.（没人知道答案。）nothing=notanything什么也没有Ihavenothingtodotoday.（我今天没什么事可做。）noneof...没有任何人；什么都没有比较：none和nobody的区别none后面常跟of，noneof可表示人或物；而nobody只能表示人。Noneofthemcananswerthequestion.（他们中没有任何一个人能回答这个问题。）Ieatnoneofthefood.（这些食物我一样也没吃。）否定副词：seldom很少，hardly几乎不重要：表示否定的词，比如never，seldom，hardly，little等放在句首时，句子要用倒装结构。Hecanhardlywritehisname.（他几乎写不出他的名字。）WeseldomwatchTV.（我们很少看电视。）C.不使用否定词而表示否定。too...to...（太……以至于不……）是不使用否定词的否定句。Heistoooldtowork.（他年纪太大了，不能工作了。）补充：不定代词的肯定形式和否定形式肯定形式否定形式肯定形式否定形式allnone；nosomethingnotanything；nothingeveryonenooneafewfeweverythingnothingalittlelittlesomenotanybothneithereitherneither；noteithereachnoone2.祈使句祈使句表示请求、命令、建议等。祈使句中通常不用主语，谓语动词一律用原形，句末用感叹号或者句号，用降调。1.肯定的祈使句Becareful!（小心！）Let’ssaygoodbyehere.（我们在此道别吧。）句型：动词原形+……（省略主语）Standup.（起立。）Bequiet,please.（请安静。）比较：陈述句和祈使句的比较Yousitdown.（你坐下来。）（祈使句）Sitdown.（坐下。）（祈使句省略主语You）A.为了加强语气，有时可以在动词之前加do。Dostudyhard.（一定要努力学习。）Dositdown.（务必请坐。）B.为了使语气显得客气，可以在祈使句的句首或句尾加上please。please在句尾时，之前一定要加一个逗号“，”。Pleasecomehere.（请到这儿来。）Gothisway,please.（请这边走。）C.祈使句中如果有唤语，一定要用逗号“，”隔开，放在句首或句尾。Justin,comehere.（贾斯廷，过来。）Hereyouare,Robert.（给你，罗伯特。）句型：Let+第一人称代词（me/us）+动词原形+……Let+第三人称代词（him/her/it/them）或名词+动词原形+……Let’sgotoMaldivesatonce.（咱们马上动身去马尔代夫吧。）Letmetryagain.（让我再试试。）Lethertelleveryone.（让她去告诉大家。）LetTomgotherehimself.（让汤姆自己去那儿。）2.否定的祈使句Don’tmakesuchanoise.（不要这么吵。）Don’tlethimdothatagain.（别让他再那么做了。）句型：Don’t+动词原形+……Don’tswimintheriver.（别在河里游泳。）Don’tbelate.（别迟到。）补充：“No+动名词”表示禁止表示禁止时，尤其是用在标语中等情况，也可用“No+动词-ing形式”。Nosmoking.（禁止吸烟。）句型：Let’s/Letus/Letme+not+动词原形+……Don’tlet+第三人称代词的宾格或名词+动词原形+……Let’snotsayanythingaboutit.（对于这件事，咱们什么也不要说。）Don’tletthemplaywithfire.（别让他们玩火。）Don’tletthemlookdownuponyou.（别让他们瞧不起你。）比较：Let’s和Letus的区别Let’s包括对方，Letus不包括对方，在反意疑问句中差别最明显。A:Let’sgo,shallwe?（咱们去吧，怎么样？）B:Yes,let’s.（好的。）/No,let’snot.（不，不要。）Letusgo,willyou?（让我们去吧，行吗？）（表示征求对方的意见）补充：祈使句有时相当于一个由if引导的条件状语从句。祈使句：Useyourhead,andyou’llfindaway.条件句：Ifyouuseyourhead,you’llfindaway.（如果你动动脑筋，就会找到方法。）3.感叹句表示喜、怒、哀、乐等强烈感情时用感叹句。感叹句分为两种：一种以what引导，一种以how引导。句尾用感叹号“!”，读降调。Whatacleverboyheis!（多么聪明的男孩啊！）Howclevertheboyis!（这个男孩多聪明啊！）1.what引导的感叹句句型：What+a/an（+形容词）+名词+陈述句！Whatabeautifulcityitis!（（这是一个）多么美丽的城市啊！）句型：What（+形容词）+可数名词复数/不可数名词+陈述句！Whatbigcoconutstheseare!（（这些是）多么大的椰子啊！）Whatniceweatheritis!（多么好的天气啊！）2.how引导的感叹句句型：How+形容词/副词+陈述句（主语+谓语）！Howhotitistoday!（今天天气多么热啊！）Howhighthekiteisflying!（那只风筝飞得多么高啊！）Howfastheruns!（他跑得多快啊！）HowIwanttobeanastronaut!（我多想当一名宇航员啊！）说明：当how修饰动词时，动词并不提前。比较：how引导的感叹句和特殊疑问句的区别感叹句：Howbusyyouare!（你多么忙啊！）（陈述句语序）疑问句：Howbusyareyou?（你有多忙？）（疑问句语序）这两种句子的根本区别在于：感叹句后面是陈述句语序，而疑问句的语序则要颠倒过来。注意：what和how引导的感叹句，在口语中常用简略式，即省略陈述句部分，如：Howcold!（多冷啊！）/Whatheavytraffic!（交通多拥挤啊！）CommonMistakes（注意！失分陷阱！）陷阱例题①A:Didyouenjoytheconcertlastnight?B:Verymuch.__________wonderfulconcertitwas!【威海中考】A.WhataB.WhatC.HowaD.How句意提示：A：你喜欢昨晚的音乐会吗？B：非常喜欢。那是一场多么棒的音乐会啊！陷阱追击：如分辨不清由what引导的感叹句与由how引导的感叹句的区别，则容易误选。正确解析：由what引导的感叹句句型为“What(a/an)+形容词+名词+（主语+谓语）！”。名词concert是可数名词单数，用冠词a修饰。正确答案为A。陷阱例题②Studyhard,__________youwillpasstheexaminEnglish.【武汉中考】A.soB.stillC.andD.unless句意提示：如果你努力学习，就会通过英语考试。陷阱追击：如没有掌握“祈使句+and+另一个简单句”的结构，则容易误选A。正确解析：“祈使句+and+另一个简单句”表示条件，相当于：Ifyoustudyhard,youwillpasstheexaminEnglish.。正确答案为C。陷阱例题③A:Dad,doyoulikemypicture?B:__________!It’sthenicestoneI’veeverseen!【兰州中考】A.WhatbeautifulB.HowcarefulC.HowwonderfulD.Whatwonderfulpicture句意提示：A：爸爸，你喜欢我的画吗？B：多么棒啊！这是我看过的最漂亮的画了！陷阱追击：本题考查根据语境判断由what和how引导的感叹句的简略式。容易误选D。正确解析：用于修饰picture的形容词应该为beautiful，wonderful，故排除B。D项中picture为可数名词单数，应用冠词a修饰，故排除。由how引导的感叹句句型为“How+形容词/副词+（主语+谓语）！”。正确答案为C。陷阱例题④Don’t__________toomuchsweetfood.It’sbadforyourteeth.A.eatingB.toeatC.eatD.ate句意提示：不要吃太多甜食。它对你的牙齿有害。陷阱追击：本题考查祈使句的否定形式，如没有掌握其特定形式，则容易误选。正确解析：祈使句由动词原形开头，其否定形式为：Don’t+动词原形。正确答案为C。FinalCheck（实力测验）1.按要求变换句型1.Thereissomemilkinthebottle.（改为否定句）_______________________________________________________________________________2.Takethechairtothedoor.（改为否定句）_______________________________________________________________________________3.Hedidthehouseworkyesterday.（改为否定句）_______________________________________________________________________________4.Theshipisbig.（改为感叹句）_______________________________________________________________________________5.Hedoeswellinmaths.（改为否定句）_______________________________________________________________________________6.Theycanputthebaginthebox.（改为否定句）_______________________________________________________________________________7.Givehimabottleofmilk.（改为否定句）_______________________________________________________________________________8.Hehaddonewiththegoodsbeforehewentaway.（改为否定句）_______________________________________________________________________________9.Thesepeopleareverybrave.（改为感叹句）_______________________________________________________________________________10.Tomhasstrongarms.（改为What引导的感叹句）_______________________________________________________________________________11.Thisfilmisverygood.（改为How引导的感叹句）_______________________________________________________________________________12.Iwanttobeadoctor.（改为感叹句）_______________________________________________________________________________13.Therewassomethingwrongwiththeradio.（改为否定句）_______________________________________________________________________________14.Youmustbekindtotheotherpeople.（改为祈使句）_______________________________________________________________________________15.Youmustn’thavelunchnow.（改为祈使句）_______________________________________________________________________________16.Shallweplaytennisafterschool?（改为祈使句）_______________________________________________________________________________17.Howcolditistoday!（改为肯定陈述句）_______________________________________________________________________________18.Ithinkhewillcome.（改为否定句）_______________________________________________________________________________19.Heworksveryhard.（改为How引导的感叹句）_______________________________________________________________________________20.Let’sgotoseethem.（改为否定句）_______________________________________________________________________________21.Lethimplayoutsideafterschool.（改为否定句）_______________________________________________________________________________2.汉译英1.他父亲很可怜，他几乎不会写他自己的名字。_______________________________________________________________________________2.我很少看报纸，我不知道每天都发生什么事。_______________________________________________________________________________3.我父亲并非每天早上都到办公室去。_______________________________________________________________________________4.好难的工作呀！_____________________________________________
