DSE五星级专题系列专题一时态一般现在时态一、导入某人刻苦学习英语,终有小成。一日上街不慎与一老外相撞,忙说:Iamsorry.老外应道:Iamsorrytoo.某人听后又道:Iamsorrythree.老外不解,问:Whatareyousorryfor某人无奈,道:Iamsorryfive.二、一般现在时态1.概述一般现在时表示习惯性、经常性、反复性的动作或存在的状态。“习惯性、经常性、反复性”是一般现在时的三大特性,它不表示特定时间内发生的事。2.构成:时态的结构指的是动词的变化形式。一般现在时间有两种结构,一种是动词原形,用于主语为非第三人称时的情况;另一种为动词的第三人称单数形式,用于主语为第三人称时的情况。oftengetupearlyinthemorning.fatheroftengetsupearlyinthemorning.3.谈谈“主语为三单,其后动词s添”在一般现在时中,当主语为第三人称单数时,谓语动词要用第三人称单数形式。可以简单叙述为“主语为三单,其后动词s添”。何谓第三人称单数用一句话概括就是“非你、非我、非复数”,如he,she,it,myfather,mymother,mysister,ourEnglishteacher,Tom,Mike,LiuJia,China,mybook,etc.sometimesgoestoschoolbybike.fatherworksinthehospitalasadoctor.4.动词第三人称单数变化规则动词第三人称变化的规则与可数名词复数变化的规则相同。1).一般在词尾加-s。如:looks,puts.reads,sees,skis等。2)以-o,-s,-x,-sh,-ch结尾的加-es。如:goes,does,misses,passes,mixes,fixes,pushes,wishes,watches,teaches,等。3)以辅音字母加y结尾的,变y为i,再加-es。注意一定是辅音字母加y才变,若是元音字母加y,则直接加-s。如:fly→flies,try→tries,fry→fries,copy→copiesbuy→buys,enjoy→enjoys,play→plays,say→says,pay→pays5.一般现在时态的用法:1).现阶段经常性,习惯性的动作或者存在的状态。Igetupatsixeverymorning.Heplaystennisonceaweek.Mymotherisateacher.SheteachesEnglishinaschool.2).客观真理例如:Theearthgoesaroundthesun.3).在条件状态从句和时间状语从句中,用一般现在时表示将来。Ifyoudon'tgosoon,you'llbelate.如果你不快去的话,你就要迟到了。Iwillwaitforyouuntilyoucomeback.我将一直等到你回来。6.常用于一般现在时态的时间状语:oftenusuallysometimesalwayseverydayneverinthemorning等。例题解析:举一反三,学的更轻松!---MayIhelpyou,sir---Yes,IboughttheTVthedaybeforeyesterday,butit______.A.didn’tworkB.doesn’tworkC.won’tworkD.can’twork2.______thebusuntilit______..A.Getoff,stopsB.Getoff,willstopC.Don’tgetoff,stopsD.Don’tgetoff,willstopA.takesB.aretakingC.tookD.willtake7.一般现在时的句子转换(1)当句子中有be动词或情态动词时,则把be动词或情态动词(can,could等等)提到主语的前面变成一般疑问句;在be动词或情态动词后面加not变成否定句.例:①陈述句:Sheisastudent.一般疑问句→Issheastudent否定句→Sheisnotastudent.②陈述句:Icanswim.一般疑问句→Canyouswim否定句→Icannotswim.(2)当句子中即没有be动词,也没有情态动词时,则在主语前加助动词do(you,以及复数),does(单数she,he,it)变成一般疑问句;在主语后谓语动词前加助动词don’t(I,you,以及复数),doesn’t(单数she,he,it)变成否定句,助动词后的动词要变成动词原形。例:①陈述句:Wegetupat7:00everymorning.一般疑问句→Doyougetupat7:00everymorning否定句→Wedon’tgetupat7:00everymorning.②陈述句:Shehasalittlebrother.一般疑问句→Doesshehavealittlebrother否定句→Shedoesn’thavealittlebrother.当堂过手训练1.写出下列动词的三单形式go__________catch_________brush(刷)_____wash___________do________like________have___________watch________drink___________fly___________say_______learn___________eat___________read___________sing___________buy__________study_______stay__________make__________look____pass__________carry____come__________plant(种植)______teach_______buy__________2.用括号内动词的适当形式填空。1.Weoften___________(play)intheplayground.2.He_________(get)upatsixo’clock.(brush)yourteetheverymorning.4.What________(do)heusually______(do)afterschool(study)English,Chinese,Maths,ScienceandArtatschool.6.Mikesometimes__________(go)totheparkwithhissister.7.Ateightatnight,sheoften__________(watch)TVwithhisparents.8.________Mike________(read)Englisheverydaymanylessons_________yourclassmate________(have)onMonday10.Whattime_________hismother_________(do)thehousework3.选择题()1.I________toschoolat7:00inthemorning.A.goB.goingC.goes()2.They_______bookseverydayinthelibrary.B.readC.reading()3.Themonkey________eatingbananasverymuch.B.likesC.liking()4.Myfather________toreadnewspaperaftersuppereveryday.B.likesC.liking()5.IlikewatchingTV,butmymother_________likeit.A.don’tB.doesn’tC.does()6.____________yourfatherdrinkmilkeverydayB.areC.does()7.Wewillgoshoppingifit____tomorrow.A.don'trainB.didn'train'trainD.isn'train()8.Hesaidthesun____intheeastand____inthewest.Arose;setBrises;setsCrises,setDrise;sets()Mei____musicandoften____tomusic.Alike;listenBlikes;listensClike;arelisteningDliking;listen()10.Jenny____Englisheveryevening.AhasstudyBstudiesCstudyDstudied4.改错(划出错误的地方,将正确的写在横线上)1.IsyourbrotherspeakEnglish__________________2.Doeshelikesgoingfishing__________________3.Helikesplaygamesafterclass.__________________4.Mr.WuteachsusEnglish.__________________5.Shedon'tdoherhomeworkonSundays._________________5.把下列句子变成一般疑问句(并作肯定和否定回答)、否定句例:Ilikecooking.→DoyoulikecookingYes,Ido.No,Idon't.Idon'tlikecooking.friendslikeplayingsoccer.speakEnglisheveryday.watchesTVeveryeveningisfromCanada.doeshishomeworkathome.dogrunsfast.likesplayingcomputergames.canplaythepianowell.一般过去式一、概念:一般过去时用来表示过去某一时间内发生的动作或存在的状态以及过去习惯性、反复性的动作。谓语动词要用动词的过去式,常和表示过去的时间状语连用,如yesterday昨天、lastnight昨晚、lastweek上周、lastyear去年,等。二、过去式及其句子结构:(可分两类不同的变化)※规则动词的过去式的变化规则1.一般情况下,在动词原形后面加-ed。look→lookedplay→playedstart→startedvisit→visited2.以不发音e结尾的动词,在词尾直接加-d。live→liveduse→used3.以“辅音字母+y”结尾的动词,先将y改为i,再加–ed。study→studiedtry→triedfly→flied4.以重读闭音节(即辅音+元音+辅音)或r音节结尾,末尾只有一个辅音字母的动词,要先双写这个辅音字母后,再加–ed。stop→stoppedplan→plannedprefer→preferred※不规则动词的过去式需特殊记忆。如:am(is)-was,are-were(是),go-went(走),come-came(来),take-took(拿),have(has)-had(有),begin(开始)--began,bring(拿来)--brought,can(能)--could,catch(捉住)--caught,cut(砍,割)--cut,do/does(做,干)--did,draw(画画,拉)--drew,drink(喝)--drank,drive(驾驶)--drove,eat(吃)--ate,fall(跌倒,落下)--fell,feel(感觉)--felt,fly(飞)--flew,get(获得)--got,give(给)---gave,grow(生长)--grew,keep(保持)--kept,know(知道,认识)--knew,learn(学习)--learnt,leave(离开)--left,let(让)
