初中语法-现在进行时

七年级下学期英语语法：现在进行时一、现在进行时(ThePresentProgressiveTense)的定义：现在进行时是表示现在正在进行或发生的动作或存在的状态，说话瞬间或当前一直正在做着的动作。如：Tonyisplayingsoccernow.托尼现在正在踢足球。now“现在”，由此可以看出托尼踢球的动作正在进行。○1表示说话时正在进行的动作常和now连用，有时用一个动词如look（看）、listen（听）来表示now（现在）这一时间概念。Look！Atrainiscoming.看！火车来了Listen！Heisplayingthepiano.听！他在弹钢琴。○2表示现阶段正在进行着的动作但不一定是说话时正在进行。常和atpresent（目前）、thisweek（本周）、thesedays（这几天）等时间状语连用。Whatlessonareyoustudyingthisweek？你们本周学哪一课了？（说话时并不在学）二、现在进行时的构成：助动词be+v-ing（动词的现在分词）注意：现在进行时态的助动词be与一般现在时态的be动词用法一致，即：当主语是第一人称I时，助动词用am；当主语是you和复数时用助动词are；当主语是第三人称单数时用助动词is。三、现在分词的构成规律：(1)一般动词后直接加-ing。如：listen---listening,wait---waiting,clean---cleaning,eat--eating(2)以不发音的字母e结尾的动词，去e再加-ing。如：live---living,take---taking,come---coming,write---writing(3)以重读闭音节结尾，且末尾只有一个辅音字母的动词，双写该辅音字母再加-ing。如：put---putting,get---getting,sit---sitting,swim---swimming,begin---beginning,shop---shopping,cut---cutting,forget---forgetting四、现在进行时的句型结构：(1)肯定陈述句：主语+be(am,is,are)+v-ing+其他。如：Theyaresittingintheclassroomnow.他们现在正坐在教室里。(2)否定句式：主语+be(am,is,are)+not+v-ing+其他。如：Heisn’tplayingfootball.(3)一般疑问句：Be(am,is,are)+主语+现在分词(动词-ing）+其它？肯定回答：Yes,主语+be(am,is,are).否定回答：No,主语+be(am,is,are)+not.如：Thegirlisswimming.变一般疑问句为：Isthegirlswimming?肯定回答是：Yes,sheis.否定回答是：No,sheisn’t.(4)特殊疑问句：疑问词+be(am,is,are)+主语+现在分词+其它？回答要根据实际情况作答，不能用Yes或No。如：---你现在在干什么？Whatareyoudoingnow?---我在写故事。Iamwritingastory.五、现在进行时的句子中常有以下特征词：①句子中有now时，常表示动作正在进行。②Look!或Listen!开头的句子，提示我们动作正在进行，用现在进行时。③在问“某人在哪里？Whereis/are+人?”时，答语常用现在进行时态表示某人现在正在什么地方做某事。④表示当前一段时间或现阶段正在进行的动作，且句中有thisweek,thesedays等时间状语时，常用现在进行时。六、一般现在时和现在进行时的区别1、一般现在时表示经常性的动作；而现在进行时表示暂时性的动作。Hewalkstowork.他步行上班。（习惯、经常性的动作）He'swalkingtoworkbecausehisbikeisbeingrepaired.他现在走着上班，因为他的自行车正在修理。（只是暂时的情况）Wheredoeshelive？他家住在哪儿？（询问一般的情况）Whereisheliving（staying）？他这几天住在哪儿？（询问暂时一段时间的情况）2、现在进行时有时可用来代替一般现在时，表达说话人的某种感惰，使句子有强烈的感情色彩。常与always，forever连用。Youarealwaysforgettingtheimportantthing.你总是把重要的事情忘掉。（表达出不满的情绪）Maryisdoingfineworkatschool.玛丽在学校学习得挺不错。【语法训练】I.写出下列动词的现在分词：1.eat____________2.play____________3.have__________4.listen____________5.do___________6.study______________7.write____________8.shop______________9.swim____________10.run_____________11.see___________12.watch____________13.come___________14.put__________15.begin_____________16.clean____________17.live_____________18.take_____________19.talk_____________20.sleep_____________II.用所给词的适当形式填空：1.---Isshe_________________(read)now?---Yes,heis.2.---Whataretheydoing?---They__________________(swim).3．Look!Theboy____________________(eat)abanana.4.---Areyou________________(get)upnow?---Yes,Iam.5.It’s11:30now.Thechildren___________________(have)lunch.6.Tom_______________(notdo)hishomeworkeverySunday,andnowhe_______________(notdo)hishomework.7.LetMary______________(clean)theroom.8.Sheoften__________________(watch)TVathome,butshe_________________(listen)tothemusicnow.9.Ioften____________(take)abustoschool,andI__________________(wait)forabusnow.10.Look!She_________________(wear)anoldskirt,shewants___________(buy)anewone.11.Billwithhisbrother_________________________(talk)aboutthemovienow.III．根据汉语意思完成句子：1.---罗斯在哪里？---她正在和朋友们在超市购物。---Where’sRose?---She_______________________inthesupermarketwithherfriends.2.我们现在在做作业。We____________________ourhomeworknow.3.这些天他在做什么?What_________he____________thesedays?4.看！是谁在扫教室？Look!________________________theclassroom.5.他没有在看电视，他在睡觉。He________________________TV.Heis_______________.单项选择（）1.我在照看孩子.(A)Iamlookingafterthebaby.(B)I'mlookafteringthebaby.(C)Ilookamafteringthebaby.(D)Ilookingafterthebaby.()2._____friend'smaking______akite.(A)I,me(B)My,my(C)My,me(D)His,his()3.Isthewoman______yellowyourteacher?(A)in(B)puttingon(C)wearing(D)having()4.Look!Thetwins_____theirmotherdothehousework.(A)arewanting(B)help(C)arehelping(D)arelooking()5._____arethebirdsdoing?Theyaresinginginatree.(A)Who(B)What(C)How(D)Where()6.Isshe____something?(A)eat(B)eating(C)eatting(D)eats()7.你在干什么?(A)Whatisyoudoing?(B)Whatareyoudo?(C)Whatareyoudoing?(D)Whatdoyoudo?()8.Whatareyoulistening_____?(A)/(B)for(C)at(D)to()9.我正在听他说话.(A)Ilisteningtohim.(B)I'mlisteningtohim.(C)I'mlistentohim.(D)I'mlisteninghim.()10.Theyare_____theirclothes.(A)makeing(B)putting(C)putaway(D)puttingon()11.Listen!She____intheclassroom.(A)issinging(B)sing(C)tosing(D)issing()12.TodayJim______hiswhiteshirtandbrowntrousers.(A)isputtingon(B)wear(C)puton(D)iswearing()13.______areyoueating?I'meating______meat.(A)What,some(B)Which,any(C)Where,not(D)What,a()14.They______TVintheevening.Theydotheirhomework.(A)arewatching(B)can'twatching(C)don'twatch(D)don'twatching()15.Thechildren_____football.(A)isplaying(B)areplaying(C)playthe(D)playa
