概述:一般现在时(ThePresentIndefinite)表示现在成为习惯或经常性的动作;现在进行时(ThePresentContinuous)则表示现在正在进行的动作。1.1现在进行时的构成肯定句:主语+am/is/are+现在分词...否定句:主语+am/is/are+not+现在分词...疑问句:Am/Is/Are+主语+现在分词...?疑问代词/疑问副词+am/is/are+主语+现在分词...?1.2现在进行时的肯定句句型:主语+am/is/are+现在分词...构成方式:Theyarecleaningthehouse.他们在打扫屋子。Heisbrushinghisteeth.他正在刷牙。Motheriswaitingforme.母亲在等我。1.3现在进行时的否定句句型:主语+am/is/are+not+现在分词...现在进行时的否定句是在助动词am/is/are后加not:I'mnotdoinganythingrightnow.我现在没做什么事情。Sheisnotdancing,butdoingexercise.她不是在跳舞,而是在锻炼。1.4现在进行时的疑问句一般疑问句句型:Am/Is/Are+主语+现在分词...?回答方式:Yes,主语+am/is/are.No,主语+am/is/are+not.现在进行时的疑问句是将助动词am/is/are置于主语之前(大写am/is/are的第一个字母),在句尾加问号;这种语序是倒装语序:Areyouleavingalready?你这么早就要走了吗?Isitrainingnow?—Yes,itis./No,itisn't.现在下雨吗?——是的,在下雨。/不,不下了。Aretheyhelpingtheoldlady?—Yes,theyare./No,theyaren't.他们在帮助这位老妇人吗?——是的。/不,没帮助她。特殊疑问句句型:疑问代词/疑问副词+am/is/are+主语+现在分词...?现在进行时的特殊疑问句是将疑问代词/疑问副词等置于助动词am/is/are之前(am/is/are的第一个字母无需大写),和一般疑问句差不多;这种语序是倒装语序。就主语提问时,将疑问代词或带有疑问限定词的名词词组置于助动词am/is/are之前,在句尾加问号;这种语序是陈述句语序:Whoareyouwaitingfor?—I'mnotwaitingforanybody.你在等谁?——我没在等谁。Whatareyoudoing?—I'mjusttyingupmyshoelaces.你在干什么?——我在系鞋带。Whatareyoulookingfor?—I'mlookingformykeys.你在寻找什么?——我在找钥匙。Whattimeareyoucomingback?—I'mnotsurewhattimeI'mcomingback.你打算什么时候回来?——我不能肯定我将在什么时候回来。What'syourbrotherplanningtodotomorrow?—Hecan'tdecidewhattodo.你兄弟明天打算做什么?——他还没定要做什么。Whereareyougoing?—I'mgoinghome.你到哪去?——我回家去。Howareyoufeelingtoday?—Idon'tfeelverywellthismorning.你今天感觉怎样?—今天早上我感觉不太舒服。由于使用了be动词,因此进行时的否定句和疑问句的构成方式与be动词的否定句和疑问句的构成方式相同。1.5现在进行时的基本用法1.表示说话时正在进行的动作常和now连用,有时和动词如look,listen等连用,表示“现在”这一概念:Listen!Birdsaresinging.听!鸟在歌唱。Look!hetrainisjustgettingintothestation.看!火车进站啦。Heisreadingnow.他在看书。Theriverisflowingfastafterlastnight'srain.昨夜下雨后,河水流速很快。Thehouseisbeingpainted.房子正在上油漆。2.表示现阶段正在进行着的动作现阶段正在进行着的动作,不一定指说话时正在进行着的动作。常和atpresent(目前),thisweek(本周),thesedays(这几天)等时间状语连用:We'relookingforahousetorentforthesummer.我们在找一栋房子想租一个夏天。Areyoutryingtofindafurnishedhouse?你是想找一栋有家具的房子吗?Whatcoursesareyoustudyingthisterm?你这学期学哪几门课?Don'ttakethatladderaway.Yourfather'susingit.别把梯子拿走,你父亲在用。(即不一定现在用)3.表示当前的动向Peoplearegettinglesstolerantofsmokingthesedays.如今人们对吸烟较为难以容忍了。Housesarecostingmorethesedays.如今房价越来越贵了。Sheisresemblinghermothermoreandmoreastheyearsgoby.随着年龄的增长,她越来越像她母亲了。4.表示事先计划好的动作(指将来)表示一个在最近按计划将进行的动作或为将来安排好的活动,通常需要一个表示时间的状语:WearespendingnextsummerinEngland.我们将要在英国度过明年夏天。I'mgettingmarriedtomorrow.我明天就要结婚了。用arrive(到达),come(到来),go(走、离去),leave(离开)等动词的现在进行时描写行程安排,有“将到达”和“将离去”的意思:He'sarrivingtomorrowmorningonthe7:30train.明天早上他将乘7时30分的火车到达。Christmasiscomingsoon.圣诞节很快就到了。I'mleavingEnglandandgoingtoliveinSpain.我将离开英国去西班牙定居。5.重复的动作副词always(表示屡次),repeatedly(再三地),forever(老是、不断地)等可与进行时连用,表示不断重复的动作:She'salwayshelpingpeople.她经常帮助别人。He'salwayscausingtrouble.他总是在制造麻烦。Thelittleboyisforeveraskingquestions.这小男孩老是没完没了地问问题。1.6一般现在时和现在进行时的区别一般现在时表示经常性的动作;现在进行时表示暂时性的动作。Doyouevereatmeat?—No,Inevereatmeat.你平常吃肉吗?——不,我从不吃肉。(习惯、经常性的动作)I'meatingmeatnow.我正在吃肉。(暂时性的动作)Mybrotheralwaysforgetstowashbehindhisears.我弟弟老是忘记洗耳后根的地方。现在进行时有时可代替一般现在时,表达说话人的某种感情色彩,与always,forever连用:Ourburglaralarmisforevergoingofffornoreason.我们的防盗报警器不知怎么常常失灵。(含有抱怨的意思)Youarealwaysforgettingtheimportantthing.你总是把重要的事情忘掉。(表达不满情绪)Howareyoufeelingtoday?你今天感觉怎样?(比Howdoyoufeeltoday?显得更亲切些。)现在进行时练习基础练习一、用所给的动词的正确形式填空:1.Theboy__________________(draw)apicturenow.2.Listen.Somegirls_______________(sing)intheclassroom.3.Mymother_________________(cook)somenicefoodnow.4.What_____you______(do)now?5.Look.They_______________(have)anEnglishlesson.6.They____________(not,water)theflowersnow.7.Look!thegirls________________(dance)intheclassroom.8.Whatisourgranddaughterdoing?She_________(listen)tomusic.9.It’s5o’clocknow.We_____________(have)suppernow10.______Helen____________(wash)clothes?Yes,sheis二、写出下列动词的现在分词形式work_______sing_______play_____study_______have_______dance________write_____take________run_________sit_________shop________swim__________lie________三、按要求改写句子1.Theboyisplayingbasketball.否定句:____________________________一般疑问句:_________________________肯定回答:_________________否定回______________________对“isplayingbasketball”提问:__________________________对“Theboy”提问:__________________________2.Theyaresingingintheclassroom.否定句:____________________________一般疑问句:_________________________肯定回答:_______________否定回答:______________________对“aresinging”提问:__________________________对“intheclassroom”提问:__________________________四、用现在进行时完成下列句子1.What_________you__________(do)?2.I_____________(sing)anEnglishsong.3.What________he____________(mend)?4.He______________(mend)acar.5.______you__________(fly)akite?Yes,_____________.6.______she___________(sit)intheboat?7.______you_____________(ask)questions?8.We_______________(play)gamesnow.9.Whatareyou_________(do)now?I___________(eat)bread.10.It’snineo’clock.Myfather_______________(work)intheoffice.11.Look,theboy___________(put)therubbishintothebin.12.__________he__________(clean)theclassroom?--No,heisn’t.He____________(play).13.WhereisMax?He___________(run)onthegrass.14.Listen,who____________(sing)inthemusicroom?--Oh,Mary_____________(sing)ther
