一般现在时态及第三人称单数(附练习及答案)第三人称单数问题一般现在时中,当主语是第三人称单数时,即常在动词原形后加-s或-es。第三人称单数变化,现归纳总结如下:1.人称代词he,she,it是第三人称单数。如:HelikeswatchingTV.他喜欢看电视。Shehaslunchattwelve.她十二点吃午餐。Itlookslikeacat.它看起来像只猫。2.单个人名、地名或称呼作主语;用第三人称单数。如:①HanMeilookslikehermother.韩梅看起来像她的母亲。②BeijingisinChina.北京在中国。③UncleWangoftenmakescakes.王叔叔经常做蛋糕。3.单数可数名词或this/that/the/a+单数可数名词作主语时,是第三人称单数。如:①Ahorseisausefulanimal.马是有用的动物。②Thisbookisyours.这本书是你的。③Thatcarisred.那辆小汽车是红色的。④ThecatisLucy's.这只猫是露茜的。4.不定代词someone,somebody,nobody,everything,something等及指示代词this,that作主语时,第三人称单数。①Everyoneishere.大家到齐了。②Thereissomethingwrongwiththewatch.这块手表有毛病。③Thisisapen.这是一支钢笔。④Thatisaneraser.那是一块橡皮擦。5.不可数名词作主语时为第三人称单数。如:①Themilkisintheglass.②Thebreadisverysmall.6.当数字或字母作主语时,看作第三人称单数。如:①6isaluckynumber.6②Iisaletter.发音规则动词原形变第三人称单数的规则与发音规律同名词单数变复数大致相同,请认真观察。1、大多数动词在词尾加“S”在清辅音后发音为[s],在浊辅音及元音后发音为[z]。如:①stop-stops[s];make-makes[s]②read-reads[z];play-plays[z]2、以辅音字母加“y”结尾的,要先将“y”变为“i”,然后在加“es”读[iz]如:fly-flies[z];carry-carries[z]study-studies[z];worry-worries3、以“s,x,ch,sh”结尾的,在词尾加“es”,发音为[iz]如:teach-teaches[iz];watch-watches[iz]4、以“o”结尾的动词,加“es”,读[z]如:go-goes[z]do-does[z]注:下面几个动词变为单数时,原词的元音部分的发音发生了较大的变化,请注意记忆。如:1、do[du:]-does[dz]2、say[sei]-says[sez]以不发音字母“e”结尾的开音节词,如果尾音是[s],[z]时,加“s”后字母“e”发音,与所加“s”一起读做[iz]。如:close-closes[iz]作业I.写出第三人称单数:wash_________match_______guess______study______finish_________go________snow______carry_________II.用所给动词的适当形式填空:1.He________TVeveryevening.(watch)2.Wealways________toschoolonfoot.(go)3.Tom,withhisclassmates,often______footballafterschool.(play)4.Yourshoes_______underthebed.(be)5.______hereand______byme.(come,stand)6.Hisuncleusually_________toworkbybus.(go)7.Ialways______upatsixinthemorning.(get)8.John________likehisfather.(look)III.完成句子根据所给中文意思,在空白处填入适当词语完成句子。每空一词,请直接在答题纸上完成,不要在此页上作答。1.该吃晚饭了。it’stimeto________________.2.你想来点儿面包吗?wouldyou________some________?3.安娜太小,还不能上学。annis________young________gotoschool.4.约翰跑得和我一样快。johnruns________fast________me.5.布莱克太太经常在英语上帮助我们。mrs.blackoften________us________ourenglish.6.老师让我们每天说英语。theteachertellsus________________englisheveryday.7.为什么不让孩子们做他们喜欢的事情?________________letthechildrendowhattheylike?Key:二、1.watches2.go3.plays4.are5.come,stand6.goes7.get,got8.looks三、1.it’stimetohavesupper.2.wouldyoulikesomebread?3.annistooyoungtogotoschool.4.johnrunsasfastasme.5.mrs.blackoftenhelpsuswithourenglish.6.theteachertellsustospeakenglisheveryday.7.whynotletthechildrendowhattheylike?一般现在时态一、一般现在时的用法:1、表示经常或者反复发生的动作.如:我每天吃午饭.Ihaveluncheveryday.2、还表示现在存在的一种状态.如:我姐姐是一位老师.Mysisterisateacher.3、客观真理,客观存在,科学事实。例如:Theearthmovesaroundthesun.地球绕着太阳转。二、一般现在时态经常与often(经常)sometimes(有时)always(总是)usually(通常)等频率词连用,也经常与everyday(每天),everyweek(每周),everymonth(每月),everyterm(每学期),everyyear(每年),onceaweek(一周一次),twiceayear(一年两次)等表示时间的词连用。三、第三人称单数问题一般现在时中,当主语是第三人称单数时,即常在动词原形后加-s或-es。四、一般现在时分类:1.一般现在时态分为be动词的一般现在时。1)be动词包括am,is,are.中文为是,这三个词的用法要随着主语的变化而变化。am用于第一人称单数(I);is用于第三人称单数(he,she,it);are用于第一人称复数(we),第二人称单数和复数(you),第三人称复数(they)。可以记住以下顺口溜:am管我,is管,她,它,他,are管大家。一般疑问句和否定句:把be动词am,is,are放在句首,回答时也要使用be动词;变为否定句时,把表示否定的not放在amisare的后面,其中可以简写为:isnot----isn't;arenot----aren't;amnot没有简写形式。注意:如果arenot,isnot放在句尾时,不能使用简写,必须写出整个单词。.AmIateacher?Yes,Iam.(No,Iamnot.)Areyouhisfriend?Yes,youare.(No,youarenot.)Issheanurse?Yes,sheis.(No,sheisnot.)否定句为:Iamnotateacher.Youarenothisfriend.Sheisnotanurse.2)实义动词的一般现在时如果句子的动词不是be动词amisare而是其他实义动词,疑问句和否定句要借助于助动词do或者does,也就是说be动词和实义动词原形不能同时使用。这里的do,does本身没有什么意义,只是帮助构成疑问句和否定句.一般疑问句读时必须用降调.do和does的使用要随着人称的变化而变化。请看下面两组句子,注意区分他们的共同点和不同点。Igotoschooleveryday.-------------Idon'tgotoschooleveryday.Hegoestoschooleveryday.------------Hedoesn'tgotoschooleveryday.Doyougotoschooleveryday?-----------Doeshegotoschooleveryday?Yes,Ido.(No,Idon't)--------------Yes,hedoes.(No,hedoesn't)当主语是第三人称单数时,肯定句为:主语+动词的s形式+宾语否定句为:主语+助动词doesn't+动词原形+宾语疑问句为:Does+主语+动词原形+宾语肯定回答和否定回答也要使用助动词does.注:1)第三人称单数用了does后面就不用动词的s形式了,而用动词原形.2)变为疑问句,要在句首加do;变为否定句,要在动词前面加donot,可以简写为don't.课堂练习一、把下列句子改成一般疑问句并做肯定、否定回答。1.Iusuallygetupatsixo’clock.?Yes,./No,.2.Weusuallywritee-mailstoeachotheronSaturdayevening.?/.3.Theyhavethesamehobby.?./.4.SuhaiandSuyanglikelisteningtomusicafterschool.?./.5.HelenusuallywatchesTVintheevening.?./.二、用词的适当形式填空。1.Whattime_________hisfather_________(do)thework?2.He_________(get)upatfiveo’clock.3.__________you_________(brush)yourteetheverymorning.4.What________(do)heusually________(do)afterschool?5.Tom________(study)English,Chinese,Maths,ScienceandArtatschool.6.Kittysometimes__________(go)totheparkwithhissister.7.Ateightatnight,she__________(watch)TVwithherparents.8.________Mike________(read)Englisheveryday?9.Howmanylessons________yourclassmates______(have)onMonday?10.Weoften___________(play)footballintheplayground.三.选择()1._____youhaveabook?A.DoB.AreC.IsD.Have()2.They_________onafarm.A.workingB.isworkC.workD.isworked()3.DoesPeterliketowatchTV?__________.A.Yes,helikeB.No,hedoesn’tC.Yes,he’dlikeD.No,helikes()4.Shedoesn’t__________herhomeworkintheafternoon.A.doingB.todoC.doesD.do()5.How____________Mr.Brown___________toAmerica?A.do,goB.is,goC.does,goD.d
