我是can。我是一个情态动词,表示说话人的语气或情态,我没有人称和数的变化,在句子中不能单独作谓语,只能和紧挨着我的动词原形一起构成复合谓语。我的基本意思是“能;会”。一、我的基本用法1.表示能力(如体力和脑力方面),意为“能;会”等。例如:CanyouspeakEnglish?你会讲英语吗?Canyouplaythepiano?你会弹钢琴吗?2.表示请求或允许,多用在口语中,意为“可以;能”等。用于疑问句中用来提出要求,用于否定句表示不允许。例如:CanIhelpyou?我能帮助你吗?Youcan’tplaybasketball.你不能玩篮球。Canyou...?“请你……好吗?”表示说话人的请求;CanI...?“我可以……吗?”用来征求对方是否允许自己做某事。如在句末加上please一词就显得更有礼貌了。例如:Canyouhelpme,please?请你帮助我好吗?3.表示可能。例如:Hecanbeathomenow.他现在可能在家。Themooncan’talwaysbefull.月亮不可能常圆。4.表示怀疑。在表达此意时,只能用于一般疑问句中,带有感情色彩。例如:Canitbetrue?那会是真的吗?二、我的句式变化如下:1.在变否定句时,直接在我后加上“not”,可缩写成can’t或cannot,但不能写成cann’t。例如:Hecanswim.→Hecan’tswim.Emmacanseethepenonthedesk.→Emmacannotseethepenonthedesk.2.在变一般疑问句时,把我直接移到主语前(原主语的首字母改成小写,第一人称应变为第二人称)即可。例如:Icanseeanorangeonthetable.→Canyouseeanorangeonthetable?其回答可用Yes,OK或Certainly等作肯定回答;用No或Sorry等作否定回答。例如:—Canyoulookaftermybooks,please?你能照看一下我的书吗?—OK.可以。用Certainly回答。此时语气更为肯定。例如:—CanIseeyourguitar?我能看看你的吉它吗?—Certainly.当然可以。将下面各组词组成句子1.________________________(an,aeroplane,hear,Lucy,can)2.___________________________(not,he,dance,can)3.____________________________?(you,can,see,what)4.____________________________(can,see,not,we,you)5._____________________________.(I,can,help,you)6._____________________________?(I,can,do,what)7._____________________________?(you,can,hearme)8._____________________________?(you,can,dance)一般现在时:表示经常性的事情。时间状语:often经常,usually通常,always总是,every每个,sometimes有时,at…在几点钟只有第三人称单数用动词三单,其余动词均用原形三单变化:1.多数在动词后加s:play—playslike—likes2.以s,x,sh,ch,o结尾的动词加esgo—goeswash--washes3.以辅音字母加y结尾,把y改i再加esfly—flies1.Weoften___________(play)intheplaygound.2.He_________(get)upatsixo’clock.3.__________you_________(brush)yourteetheverymorning.4.What_________(do)heusually_________(do)afterschool?5.Danny_________(study)english,chinese,maths,scienceandartanschool.6.Mikesometimes__________(go)totheparkwithhissister.7.Ateightatnight,she__________(watch)tvwithhisparents.8.________mike________(read)englisheveryday?9.Howmanylessons_________yourclassmate________(have)onmonday?()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.does,goes()6.Where’smycamera?I____________it.A.amnotfindingB.amnotseeingC.can’tfindD.can’tlookat()7.How___________hegotoworkHe___________toworkbybike.A.does;goB.do;goesC.do;goD.does;goes()8._____youusuallylateforschool?No,________.A.Do;IamB.Does;notC.Are;I’mnotD.Are;Iaren’t()9._____she_____homeatsixeveryday?A.Is,leaveB.Does,leaveC.Is,leavesD.Does,left()10.Mr.Yang____________Englishthisterm.A.teachesourB.teachesusC.teachsusD.teachour
