全解精讲+分层练习

学习目标1.理解现在进行时的核心定义，分清两种核心用法的区别。2.熟练掌握现在进行时的肯定、否定、疑问句式结构。3.牢记动词-ing的4种变化规则，能准确写出动词-ing形式。4.分清可用于和不可用于现在进行时的动词，避免误用。5.能完成多种题型练习，灵活运用现在进行时解决实际题目。现在进行时—定义详解核心定义：表示两种场景的动作，是七下重点语法之一。1.此时此刻正在进行/发生的动作（强调“正在做”）。例：Iamreadingabooknow.（我现在正在看书）2.现阶段正在进行，但此刻不一定正在做的动作（强调“现阶段”）。例：SheislearningEnglishthesedays.（她这些天在学英语）现在进行时—核心结构（肯定句+否定句）一、肯定句：主语+am/is/are+动词-ing搭配规则：I用am，you用are，he/she/it用is例句：Heisplayingfootball.（他正在踢足球）二、否定句：主语+am/is/are+not+动词-ing口诀：肯定句变否定，be动词后面加not例句：SheisnotwatchingTV.（她没在看电视）现在进行时—核心结构（疑问句）一、一般疑问句：Am/Is/Are+主语+动词-ing+其他？回答：Yes,主语+am/is/are./No,主语+am/is/are+not.例句：—Areyoureading?（你在看书吗？）—Yes,Iam./No,I’mnot.二、特殊疑问句：疑问词+am/is/are+主语+动词-ing+其他？常用疑问词：what,who,where,how例句：Whatishedoing?（他正在做什么？）动词-ing变化规则（一）——一般情况+不发音e结尾规则1：一般动词（无特殊变化），直接加-ing

例：work→working（工作）、feel→feeling（感觉）eat→eating（吃）、wait→waiting（等待）规则2：以不发音的e结尾，去e后加-ing核心要点：e不发音才去，发音e不删（如see→seeing）例：write→writing（写）、make→making（制作）动词-ing变化规则（二）——ie结尾+重读闭音节规则3：以ie结尾的动词，变ie为y，再加-ing例句：tie→tying（系）、lie→lying（躺）die→dying（死）规则4：重读闭音节（辅元辅结构），双写末尾辅音加-ing核心要点：重读、闭音节、末尾辅元辅，三者缺一不可例句：run→running（跑）、stop→stopping（停止）动词-ing变化规则—易错点提醒1.不发音e结尾：区分“发音e”和“不发音e”，避免误删e。错误：see→seeing（正确：seeing，e发音不删）2.重读闭音节：末尾只有一个辅音才双写，多辅音不双写。错误：work→working（正确：working，末尾k前是or，非辅元辅）3.ie结尾：牢记“变ie为y”，不可直接加-ing。错误：tie→tieing（正确：tying）现在进行时用法（一）——此刻正在进行的动作用法1：表示此时此刻（说话瞬间）正在进行的动作。标志词：now（现在）、rightnow（此刻）、look（看）、listen（听）例句1：Look!Theyarewateringthetrees.（看！他们正在浇树。）例句2：Rightnow,mymotheriscookingdinner.例句3：Listen!Someoneissinginginthenextroom.现在进行时用法（二）——现阶段正在进行的动作用法2：表示现阶段正在进行，但此刻不一定正在做的动作。标志词：thesedays（这些天）、thisweek（这周）、recently（最近）例句1：Weareworkingonourgroupprojectthesedays.例句2：Heislearningtoswimthismonth.（他这个月在学游泳。）例句3：Myfatherisbusythesedays;heiswritingareport.现在进行时用法（三）——即将发生的动作用法3：表示即将发生的动作，仅限“移动性动词”使用。常用移动性动词：go（去）、leave（离开）、come（来）、arrive（到达）标志词：tomorrow（明天）、nextweek（下周）、soon（很快）例句1：HeisleavingforBeijingtomorrow.（他明天要去北京。）例句2：TheyarecomingtoourschoolnextMonday.不用于现在进行时的动词（一）核心原则：表示状态、情感、感官的动词，通常不用现在进行时。这类动词表示“静态”，而非“动态动作”，常用一般现在时。第一类：表情感的动词常见词汇：like（喜欢）、love（爱）、hate（讨厌）、want（想要）、prefer（更喜欢）例句：Ilikeeatingapples.（不用amliking）不用于现在进行时的动词（二）第二类：表认知的动词常见词汇：know（知道）、believe（相信）、understand（理解）、例句：Heknowstheanswer.（不用isknowing）错误：Iamunderstandingyourproblem.（正确：Iunderstandyourproblem.）第三类：表感官的动词常见词汇：hear（听见）、see（看见）、smell（闻起来）、taste（尝起来）例句：Thecaketastesgood.（不用istasting）易混点辨析—现在进行时vs一般现在时1.现在进行时：表“正在做”或“现阶段进行”，强调动作的持续性。标志词：now,look,listen,thesedays例句：Sheisreadingabooknow.（此刻正在读）2.一般现在时：表“经常性、习惯性动作”或“客观事实”。标志词：everyday,usually,always,often例句：Shereadsbookseveryevening.（每天晚上读）辨析：Heiseatinganapple.（正在吃）vsHeeatsappleseveryday.（习惯吃）基础练习（一）—写出动词的-ing形式请根据动词-ing变化规则，写出下列动词的正确-ing形式：1.read→___________2.take→_____________3.lie→_____________4.sit→_____________5.play→_____________6.have→_____________7.shop→_____________8.die→_____________9.watch→_____________10.run→_____________readingtakinglyingsittingplayinghavingshoppingdyingwatchingrunning基础练习（二）—用动词正确形式填空1.Look!Thechildren___________(play)ontheplayground.2.Rightnow,mysister________________(draw)apicture.3.Listen!Thebirds___________(sing)inthetree.4.I_________________(notdo)myhomeworknow;I’mresting.5.___________you___________(drink)water?areplayingisdrawingaresingingamnotdoingAredrinking基础练习（三）—用动词正确形式填空（现阶段动作）用括号内动词的现在进行时形式填空，结合现阶段标志词：1.We______________(learn)anewlessonthesedays.2.Myfather______________(work)inanewcompanythismonth.3.They_________________(notplay)footballrecently;theyarebusy.4.She_______________(practice)thepianothisweek.5.___________yourbrother___________(study)forthetestthesedays?arelearningisworkingarenotplayingispracticingArestudying基础练习（四）—用动词正确形式填空（易错题）注意区分可用于和不可用于现在进行时的动词：1.He___________(like)playingbasketball.2.I___________(feel)coldnow.3.She___________(know)theanswertothequestion.4.Theflowers___________(smell)good.5.They________________(plan)atripthesedays.likesamfeelingknowssmellsareplanning单项选择1.—What_______you_________now?—I___________myroom.A.do;do;cleanB.are;doing;amcleaningC.are;do;cleanD.do;doing;amcleaning2.Look!Thecat___________afterthemouse.A.runB.runsC.isrunningD.running3.Mymother___________dinnernow;pleasebequiet.A.cooksB.iscookingC.cookD.cookingBCB4.—___________yourfather___________anewspaper?—Yes,heis.A.Is;readingB.Do;readC.Are;readingD.Does;read5.I___________TVatthemoment;I’mdoingmyhomework.A.amnotwatchingB.notwatchC.don’twatchD.amwatching6.They___________anewhousethesedays.A.lookforB.arelookingforC.looksforD.lookingforAAB单项选择（提升题）1.She___________thisbookbecauseit’sveryinteresting.A.islikingB.likesC.likeD.liking2.He___________toShanghaitomorrow;heispackinghisbagnow.A.goB.goesC.isgoingD.going3.Thesoup___________delicious;youshouldtryit.A.tastesB.istastingC.tasteD.tastingBCA单项选择（提升题）4.We________totheparkeverySunday,buttodaywe_________athome.A.go;arestayingB.aregoing;stayC.go;stayD.aregoing;arestaying5.—What_________thestudents__________?—Theyarehavingaclass.A.do;doB.are;doingC.does;doD.is;doing6.He__________tired,buthe__________working.A.is;isB.is;areC.are;isD.are;areABA句型转换（一）—肯定句变一般疑问句1.Theyareplantingtreesinthegarden.（改为一般疑问句）___________they___________treesinthegarden?回答：Yes,___________./No,___________.2.Sheiswritingalettertoherfriend.（改为一般疑问句）___________she___________alettertoherfriend?回答：Yes,___________./No,___________.Areplantingtheyaretheyaren’tIswritingsheissheisn’t句型转换（二）—肯定句变否定句1.Iamreadingastorybook.（改为否定句）I________________________________astorybook.2.Heisplayingfootballwithhisfriends.（改为否定句）He______________________footballwithhisfriends.3.Theyareworkingonaprojectthesedays.（改为否定句）They______________________onaprojectthesedays.amnotreadingisn’tplayingaren’tworking句型转换（三）—对划线部分提问1.Sheisdrawingacat.
