中学英语之家||我们致力于为您提供最全的免费、免注册即可下载的教学资源中学英语之家简易英语语法动词的分类Be动词:is,am,are,was,were助动词:do,does,did,has,have,had动词情态动词:can,must,may,should,等实义动词:run,eat,play,like,等等。陈述句改为一般疑问句的改法:一般疑问句:以be动词、助动词、情态动词为句首,句末有问号(?)的句子。例如:Issheadoctor.她是一名医生吗?Hasshegotanygrapes?她有些葡萄吗?(这里的has是助动词,got(get的原形)是有的意思。Canyoufly?你会飞吗?当句子中的谓语只有实义动词,没有be动词、助动词、情态动词的时候,句子变一般疑问句时要加do、does、did(do、dose的过去式)其中之一。如:Thefoxlikesgrapes.句子的谓语没有be动词、助动词、情态动词,只有likes,like是实义动词,因此,句首要加助动词;又因为thefox是第三人称单数,句首的助动词就用does.句子的就变成Doesthefoxlikegrapes?注意原来likes中的s,要删除。一般疑问句主语和be动词、助动词、情态动词倒装。没有这三类词时要加助动词。如:Sheisadoctor.Sheusuallygoestoschoolatseven.Issheadoctor?Doessheusuallygotoschoolatseven?记住:实义动词始终在主语的后面。注意:述句(句子后面只有句号的句子)给成一般疑问句时,一般情况下,还要把第一人称I、we、my、our改成you、your,把some变成any。如:Ihavegotsomeapples.Iammakingmyaeroplane.变成:Haveyougotanyapples?Areyoumakingyouraeroplane?WearewatchingTV.变成:AreyouwatchingTV?还要注意:如果has、have、had、do、does、did后面是名词时,has、have就不是助动词了,他们是实义动词。改一般疑问时不能提前(一般情况下,所有实义动词都不能提到主语前面),要根据时态加助动词do、does、did。如:Shehasbreakfasteveryday.Doesshehavebreakfasteveryday?练习,把下列的句子改成一般疑问句。中学英语之家||我们致力于为您提供最全的免费、免注册即可下载的教学资源中学英语之家1.HisfatherisanEnglishteacher.2.Thesecatsarecrying.3.Theycanswim.4.IliketoreadEnglish.5.Igotoschoolonfoot.6.HelikesEnglish.7.Hisfathergoestoworkbybus.8.Heiscryingunderthetree.9.HisbirthdayisonthetwentiethofNovember.10.Mrs.LiandKittyareinabigshop.11.Kittyiswearinghernewuniform.12.Theboyunderthetreeishungry.13.Hegoestoschooleveryday.14.Iwanttohaveamodelcar.15.Shewantsacupofcoffee.16.Mrs.LiandKittywatchtelevisionatnight.17.Idomyhomeworkafterschool.18.Ihavegotsomegrapes.19.Tom’sgotabird.20.KittyandTomhavegotadog.21.Ihavebreakfast(早饭)everymorning.中学英语之家||我们致力于为您提供最全的免费、免注册即可下载的教学资源中学英语之家22.Theydotheirhomeworkafterschool(放学).答案:1.IshisfatheranEnglishteacher?2.Arethesecatscrying?3.Cantheyswim?4.DoyouliketoreadEnglish?5.Doyougotoschoolonfoot?6.DoeshelikeEnglish?7.Doeshisfathergotoworkbybus?8.Ishecryingunderthetree?9.IshisbirthdayonthetwentiethofNovember?10.ArMrs.LiandKittyinabigshop?11.IsKittywearinghernewuniform?12.Istheboyunderthetreehungry?13.Doeshegotoschooleveryday?14.Doyouwanttohaveamodelcar?15.Doesshewantacupofcoffee?16.DoMrs.LiandKittywatchtelevisionatnight?17.Doyoudoyourhomeworkafterschool?18.Haveyougotanygrapes?19.Hasyougotabird?20.HaveKittyandTomgotadog?21.Doyouhavebreakfasteverymorning?这里的have是吃的意思。22.Dotheydotheirhomeworkafterschool?dotheirhomework中的do是做的意思。否定句的改法首先要认清“否”就是“不”的意思,在英语中就是not或not的省略形式n’t。否定句是在be动词、助动词、情态动词后加not或not的缩略形式n’t。人称不变化。实义动词不能直接加否定词,须加助动词doesn’t(第三人称单数)、don’t、didn’t。例如:IamEnglishteacher.改成:Iamnot(aren’t也可以)Englishteacher.Shehasgotsomeapples.改成:Shehasn’t(hasnot也可以)gotanyapples.注意:一些否定词hardly(几乎不)few(很少可数)little(很少不可数)nothing(没有)none(没有人或物)等也是否定词。含有此类否定词的句子也是否定句。amnot的否定缩略形式是aren’t如:Suyangoftenplaysfootball.可以改成:Suyangdoesn'tplayfootball(atall).Suyangseldomplaysfootball.Suyangneverplaysfootball.Some改成否定句一般也要改成any。中学英语之家||我们致力于为您提供最全的免费、免注册即可下载的教学资源中学英语之家练习,将下列句子改为否定句。1.HisfatherisanEnglishteacher.2.Thesecatsarecrying.3.Theycanswim.4.IliketoreadEnglish.5.Igotoschoolonfoot.6.HelikesEnglish.7.Mrs.LiandKittywatchtelevisionatnight.8.Idomyhomeworkafterschool.9.Ihavegotsomegrapes.10.Tom’sgotabird.11.Ihavebreakfast(早饭)everymorning.12.Theydotheirhomeworkafterschool(放学).13.Kittyoftengoestothecinema(去看电影).答案:1.Hisfatherisn’tanEnglishteacher./isnot2.Thesecatsaren’tcrying./arenot3.Theycan’tswim./cannot/cannot4.Idon’tliketoreadEnglish./donot5.Idon’tgotoschoolonfoot./donot6.Hedoesn’tlikeEnglish./doesnot7.Mrs.LiandKittydon’twatchtelevisionatnight./donot8.Idon’tdomyhomeworkafterschool./donot9.Ihaven’tgotsomegrapes./havenot10.Tomhasn’tgotabird./hasnot11.Idon’thavebreakfasteverymorning./donot12.Theydon’tdotheirhomeworkafterschool./donot13.Kittyseldomgoestothecinema./never/does…atall特殊疑问句的改法:中学英语之家||我们致力于为您提供最全的免费、免注册即可下载的教学资源中学英语之家特殊疑问句是以特殊疑问词为句首,句末有问号的句子。特殊疑问词包括what(什么)、when(什么时候)、who(谁)、which(哪个)、where(在哪里)和how(怎么)基本疑问词(5w,1h),和多种由基本疑问词变化的疑问词。如由what变化的的whattime(时间点)、whatday(星期几)、whatkind(什么种类)、whatcolor(什么颜色)、whatshape(什么形状)、whatlength(什么长度)等。由who变化的whose(谁的)、whom(谁,宾格)。由which变化的whichbook(哪个苹果)、whichpens(那支笔)等。由how变化的howlong(多长时间)、howsoon(多快,时间的快,多用在将来时态)、howoften(多久几次)、howold(多大,年龄大小)、howfar(多远,距离)、howmany/much(多少数量,many+复数,much+不可数)等。注意:特殊疑问句和一般疑问句一样,一般情况下要有倒装。如:Iamreading.Whatareyoudoing?但如果对主语的提问,则主语谓语不倒装。如:Kittylikesgrapes.Wholikesgrapes?What是对名词的提问。What’syournam?I’mTom.Whatareyoudoing?I’mreading.Whatdayistoday?ItisTuesday.Whatcoloristheball?Theballisred.Whatkindistheanimal(动物)?Theanimalisafish.Whatshapeisthesweet?Thesweetissquare.Whatlengthisthestring?Thestringis3centimeters.Who对谁或身份提问,以便进一步搞清情况。Whoisyourmother?Thewomaninredismymother.WhoistheboybesideMissFang?HeisKitty’sbrother.Whosepensarethese?TheyareBen’spen.Whom(who)doyoulike?Ilikemygrandfatherbest.Which对选择具体单位提问。Whichdoyoulikebest?Iliketheredpen.Whichbookisyours.Theyellowbookismine.WhichpensisKitty’s.TheyellowpenisKitty’sHow对方式、程度、状况等提问。Howareyou?I’mfine.HowwillyougotoShanghai?IwillgotoShangha
