人教版初二英语语法总结及复习要点

初二英语语法总结1)leave的用法1.“leave+地点”表示“离开某地”。例如：WhendidyouleaveShanghai?你什么时候离开上海的？2.“leavefor+地点”表示“动身去某地”。例如：NextFriday,AliceisleavingforLondon.下周五，爱丽斯要去伦敦了。3.“leave+地点+for+地点”表示“离开某地去某地”。例如：WhyareyouleavingShanghaiforBeijing?你为什么要离开上海去北京？2)情态动词should“应该”学会使用should作为情态动词用，常常表示意外、惊奇、不能理解等，有“竟会”的意思，例如：HowshouldIknow?我怎么知道？Whyshouldyoubesolatetoday?你今天为什么来得这么晚？should有时表示应当做或发生的事，例如：Weshouldhelpeachother.我们应当互相帮助。我们在使用时要注意以下几点：1.用于表示“应该”或“不应该”的概念。此时常指长辈教导或责备晚辈。例如：Youshouldbeherewithcleanhands.你应该把手洗干净了再来。2.用于提出意见劝导别人。例如：Youshouldgotothedoctorifyoufeelill.如果你感觉不舒服，你最好去看医生。3.用于表示可能性。should的这一用法是考试中常常出现的考点之一。例如：Weshouldarrivebysuppertime.我们在晚饭前就能到了。3)What.?与Which.?1.what与which都是疑问代词，都可以指人或事物，但是what仅用来询问职业。如：Whatisyourfather?你父亲是干什么的？该句相当于：Whatdoesyourfatherdo?Whatisyourfathersjob?Which指代的是特定范围内的某一个人。如：-WhichisPeter?哪个是皮特？-TheboybehindMary.玛丽背后的那个男孩。2.What.?是泛指，所指的事物没有范围的限制；而Which.?是特指，所指的事物有范围的限制。如：Whatcolordoyoulikebest?（所有颜色）你最喜爱什么颜色？Whichcolordoyoulikebest,blue,greenoryellow?（有特定的范围）你最喜爱哪一种颜色？3.what与which后都可以接单、复数名词和不可数名词。如：WhichpicturesarefromChina?哪些图片来自中国？4)频度副词的位置1.常见的频度副词有以下这些：always（总是，一直）usually（通常）often（常常，经常）sometimes（有时候）never（从不）2.频度副词的位置：a.放在连系动词、助动词或情态动词后面。如：Davidisoftenarriveslateforschool.大卫上学经常迟到。b.放在行为动词前。如：Weusuallygotoschoolat7:10everyday.我们每天经常在7：10去上学。c.有些频度副词可放在句首或句尾，用来表示强调。如：SometimesIwalkhome,sometimeIridesabike.有时我步行回家，有时我骑自行车。3.never放在句首时，主语、谓语动词要倒装。如：NeverhaveIbeenthere.5)everyday与everyday1.everyday作状语，译为“每一天”。如：Wegotoschoolat7:10everyday.我们每天7：10去上学。IdecidetoreadEnglisheveryday.我决定每天读英语。2.everyday作定语，译为“日常的”。ShewatcheseverydayEnglishonTVafterdinner.她晚饭后在电视上看日常英语。Whatsyoureverydayactivity?你的日常活动是什么？6)什么是助动词1.协助主要动词构成谓语动词词组的词叫助动词（AuxiliaryVerb）。被协助的动词称作主要动词（MainVerb）。助动词自身没有词义，不可单独使用，例如：HedoesntlikeEnglish.他不喜欢英语。（doesnt是助动词，无词义；like是主要动词，有词义）2.助动词协助主要动词完成以下功用，可以用来：a.表示时态，例如：Heissinging.他在唱歌。Hehasgotmarried.他已结婚。b.表示语态，例如：HewassenttoEngland.他被派往英国。c.构成疑问句，例如：Doyoulikecollegelife?你喜欢大学生活吗？DidyoustudyEnglishbeforeyoucamehere?你来这儿之前学过英语吗？d.与否定副词not合用，构成否定句，例如：Idontlikehim.我不喜欢他。e.加强语气，例如：Docometothepartytomorrowevening.明天晚上一定来参加晚会。Hedidknowthat.他的确知道那件事。3.最常用的助动词有：be,have,do,shall,will,should,would7)forgetdoing/todo与rememberdoing/todo1.forgettodo忘记要去做某事。(未做)forgetdoing忘记做过某事。(已做)Thelightintheofficeisstillon.Heforgottoturnitoff.办公室的灯还在亮着，它忘记关了。(没有做关灯的动作)Heforgotturningthelightoff.他忘记他已经关了灯了。(已做过关灯的动作)Dontforgettocometomorrow.别忘了明天来。(tocome动作未做)典型例题-Thelightintheofficeisstillon.-Oh，Iforgot_.A.turningitoffB.turnitoffC.toturnitoffD.havingturneditoff答案：C。由thelightisstillon可知灯亮着，即关灯的动作没有发生，因此用forgettodosth.而forgetdoingsth表示灯已经关上了，而自己忘记了这一事实。此处不符合题意。2.remembertodo记得去做某事(未做)rememberdoing记得做过某事(已做)Remembertogotothepostofficeafterschool.记着放学后去趟邮局。Dontyourememberseeingthemanbefore?你不记得以前见过那个人吗?8)Itsforsb.和Itsofsb.1.forsb.常用于表示事物的特征特点，表示客观形式的形容词，如easy,hard,difficult,interesting,impossible等：Itsveryhardforhimtostudytwolanguages.对他来说学两门外语是很难的。2.ofsb的句型一般用表示人物的性格，品德，表示主观感情或态度的形容词，如good,kind,nice,clever,foolish,right。Itsveryniceofyoutohelpme.你来帮助我，你真是太好了。3.for与of的辨别方法：用介词后面的代词作主语，用介词前边的形容词作表语，造个句子。如果道理上通顺用of，不通则用for。如：Youarenice.(通顺，所以应用of)。Heishard.(人是困难的，不通，因此应用for。)9)对两个句子的提问新目标英语在命题中有将对句子划线提问这一题型取消的趋势，现在采取的作法是对一个句子进行自由提问。例如：句子：Theboyinbluehasthreepens.提问：1.Whohasthreepens?2.Whichboyhasthreepens?3.Whatdoestheboyinbluehave?4.Howmanypensdoestheboyinbluehave?很显然，学生多了更多的回答角度，也体现了考试的灵活性。再如：句子：Heusuallygoestotheparkwithhisfriendsat8:00onSunday.提问：1.Whousuallygoestotheparkwithhisfriendsat8:00onSunday?2.Wheredoesheusuallygowithhisfriendsat8:00onSunday?3.Whatdoesheusuallydowithhisfriendsat8:00onSunday?4.Withwhomdoesheusuallygototheparkat8:00onSunday?5.WhattimedoesheusuallygototheparkwithhisfriendsonSunday?6.Whendoesheusuallygototheparkwithhisfriends?10)so、such与不定冠词的使用1.so与不定冠词a、an连用，结构为“so+形容词+a/an+名词”。如：Heissofunnyaboy.Jimhassobigahouse.2.such与不定冠词a、an连用，结构为“such+a/an+形容词+名词”。如：Itissuchaniceday.Thatwassuchaninterestingstory.11)使用-ing分词的几种情况1.在进行时态中。如：HeiswatchingTVintheroom.Theyweredancingatnineoclocklastnight.2.在therebe结构中。如：Thereisaboyswimmingintheriver.3.在havefun/problems结构中。如：WehavefunlearningEnglishthisterm.Theyhadproblemsgettingtothetopofthemountain.4.在介词后面。如：Thanksforhelpingme.Areyougoodatplayingbasketball.5.在以下结构中：enjoydoingsth乐于做某事finishdoingsth完成做某事feellikedoingsth想要做某事stopdoingsth停止做某事forgetdoingsth忘记做过某事goondoingsth继续做某事rememberdoingsth记得做过某事likedoingsth喜欢做某事keepsbdoingsth使某人一直做某事findsbdoingsth发现某人做某事see/hear/watchsbdoingsth看到/听到/观看某人做某事trydoingsth试图做某事needdoingsth需要做某事preferdoingsth宁愿做某事minddoingsth介意做某事practicedoingsth练习做某事bebusydoingsth忙于做某事canthelpdoingsth禁不住做某事missdoingsth错过做某事12)英语中的“单数”1.主语的第三人称单数形式，即可用“he,she,it”代替的。如：he,she,itmyfriend,histeacher,ourclassroom,Tom,Marysuncle2.名词有单数名词和复数名词。如：man（单数）-men（复数）banana（单数）-bananas（复数）3.动词有原形，第三人称单数形式，-ing分词，过去式，过去分词。如：go-goes-going-went-gonework-works-working-worked-workedwatch-watches-watching-watched-watched当主语为第三人称单数的时候，谓语动词必须用相应的第三人称单数形式。如：Theboywantstobeasalesassistant.OurEnglishteacherisfromtheUS.Theirdaughtermakesherbreakfastallbyherself.13)名词的复数构成的几种形式名词复数的构成可分为规则变化和不规则变化两种。I名词复数的规则变化1.一般在名词词尾加-s。如：pear-pearshamburger-hamburgersdesk-deskstree-trees2.以字母-s,-sh,-ch,-x结尾的名词，词尾加-es。如：class-classesdish-disheswatch-watchesbox-boxes3.以字母-o结尾的某些名词，词尾加-es。如：potato-potatoestomato-tomatoesNegro-Negroeshero-heroes4.以辅音字母加-y结尾的名词，将-y变为-i,再加-es。如：family-familiesdictionary-dictionariescity-citiescountry-countries5.以字母-f或-fe结尾的名词，将-f或-fe变为-v，再加-es。如：half-halvesleaf-leavesthief-thievesknife-knivesself-selveswife-wiveslife-liveswolf-wolvesshelf-shelvesloaf-loaves但是：scarf-scarves(fes)roof-roofsserf-serfsgulf-gulfschief-chiefsproof-proofsbelief-beliefsII名词复数的不规则变化1.将-oo改为-ee。如：foot-feettooth-teeth2.将-man改为-men。如：man-menwoman-womenpoliceman-policemenpostman-postmen3.添加词尾。如：child-children4.单复数同形。如：sheep-sheepdeer-deerfish-fishpeople-people5.表示“某国人”的单、复数变化。即“中日瑞不变英法变，其它国把-s加后面”。如：Chinese-ChineseJapanese-JapaneseSwiss-SwissEnglishman-EnglishmenFrenchman-FrenchmenAmerican-AmericansAustralian-AustraliansCanadian-CanadiansKorean-KoreansRussian-RussiansIndian-Indians6.其它。如：mouse-miceappletree-appletreesmanteacher-menteachers14)双写最后一个字母的-ing分词初中阶段常见的有以下这些：1.letletting让hithitting打、撞cutcutting切、割getgetting取、得到sitsitting坐forgetforgetting忘记putputting放setsetting设置babysitbabysitting临时受雇照顾婴儿2.shopshopping购物triptripping绊stopstopping停止dropdropping放弃3.traveltravel(l)ing旅游swimswimming游泳runrunning跑步digdigging挖、掘beginbeginning开始preferpreferring宁愿planplanning计划15)肯定句变否定句及疑问句要变化的一些词1.some变为any。如：Therearesomebirdsinthetree.Therearentanybirdsinthetree.但是，若在表示请邀请、请求的句子中，some可以不变。如：Wouldyoulikesomeorangejuice?与此相关的一些不定代词如something,somebody等也要进行相应变化。2.and变为or。如：Ihaveaknifeandaruler.Idonthaveaknifeoraruler.3.alotof(=lotsof)变为many或much。如：Theyhavealotoffriends.（可数名词）Theydonthavemanyfriends.Thereislotsoforangeinthebottle.（不可数名词）Thereisntmuchorangeinthebottle.4.already变为yet。如：Ihavebeentherealready.Ihaventbeenthereyet.16)in与afterin与after都可以表示时间，但二者有所区别。1.in经常用于将来时的句子中，以现在为起点，表示将来一段时间。如：HewillleaveforBeijinginaweek.一周后他会动身去北京。2.after经常用于过去时的句子中，以过去为起点，表示过去一段时间。如：HeleftforBeijingafteraweek.一周后他动身去了北京。不过，如果after后跟的是具体的时刻，它也可用于将来时。如：Wewillfinishtheworkaftertenoclock.十点后我们会完成工作的。3.注意区分以下的in的用法。Illvisithiminaweek.一周后我会去拜访他。Illvisithimtwiceinaweek.一周内我会去拜访他两次。17)不定冠词a与an的使用1.a用在以辅音音素开头的单词前。如：Thereisabinthewordbook.单词book中有个字母b。类似的字母还有：c,d,g,j,k,p,q,t,u,v,w,y,z。Shehasasmallknife.她有一把小刀。2.an用于以元音音素开头的单词前。如：Thereisaniinthewordonion.单词onion中有个字母i。类似的字母还有：a,e,f,h,l,m,n,o,r,s,x。Doyouhaveanumbrella?你有一把雨伞吗？3.以元音字母开头的单词前面不一定都用an；以辅音字母开头的单词前面也不一定都用a。如：ausefulbookauniverseaone-letterwordanhouranuncleanumbrellaanhonestperson18)如何表达英语中的“穿、戴”？英语中表示“穿、戴”的表达方法有好几种，常见的有以下这些：1、puton主要表达“穿”的动作。如：Heputonhiscoat.他穿上了他的外套。Youdbetterputonyourshoes.你最好穿上你的鞋子。2、wear主要表示“穿、戴”的状态。如：Theoldmanwearsapairofglasses.老人戴着一副眼镜。Thegirliswearingaredskirt.那女孩穿着一条红色的短裙。3、dress可作及物动词，有“给.穿衣”的意思，后接“人”，而不是“衣服”。如：Pleasedressthechildrenrightnow.请立即给孩子们穿上衣服。dress也可作不及物动词，表示衣着的习惯。如：Thewomanalwaysdressesingreen.那位妇女总是穿绿色的衣服。4、bein表示穿着的状态。如：Johnisinwhitetoday.约翰今天穿白色的衣服。Themaninblackisafootballcoach.19)alittle,afew与abit(of)alittle,afew与abit(of)都有“一些、少量”的意义。他们的区别在哪里呢？1.alittle意为“一些、少量”，后接不可数名词。如：Thereisalittlewaterinthebottle.瓶子里有一点水。还可以接形容词。如：Heisalittleshy.他有些害羞。2.afew意为“一些、少数”，后接复数的可数名词。如：Thereareafewpeopleintheroom.房间里有一些人。3.abit意为“一点儿”，后接形容词。如：Itsabitcold.有点冷。abitof后接不可数名词。如：Hehasabitofmoney.他有一点儿钱。4.alittle表肯定意义，little表否定意义；afew表肯定意义，few表否定意义。如：Thereisalittlesodaintheglass.杯子里有一点儿汽水。Thereislittlesodaintheglass.杯子里几乎没有汽水了。IhaveafewChinesefriends.我有一些中国朋友。Fewpeoplelikehim.几乎没有人喜欢他。5.alittle=abitof,后接不可数名词；alittle=abit=alittlebit=kindof,后接形容词，意为“有点儿”。20)关于like的用法like可以作动词，也可以作介词。1、like作动词，表示一般性的“爱好、喜欢”，有泛指的含义。如：Doyoulikethecolor?你喜爱这种颜色吗？like后可接不定式（liketodosth），也可接动词的-ing分词（likedoingsth），有时意思不尽相同。如：Shelikeseatingapples.她喜爱吃苹果。（习惯）Shelikestoeatanapple.她喜爱吃一粒苹果。（平常不喜欢吃）like与would连用，后接不定式，表示愿望或客气的请求。如：Wouldyoulikeacupoftea?您愿意喝杯茶吗？“喜欢某人做某事”可以用结构“likesbtodosth/doingsth”。如：Theyalllikemetosing/singingEnglishsongs.他们都喜欢我唱英文歌。2、like作介词，可译成“像.”。如：Sheisfriendlytouslikeamother.她对我们友好，就像母亲一样。Itlookslikeanorange.它看起来像个桔子。3、区分以下句子：A.Whatdoeshelooklike?B.Whatishelike?A句译为“他长相如何？”指一个人的外貌特征；而B句译为“他人怎么样？”指人的性格特点。C.TheboylikePeterisoverthere.D.AboylikePetercantdoit.A句指外貌相似，而D句指性格相似。21)stoptodosth与stopdoingsth1.stoptodosth意为“停下来去做某事”。如：Thestudentsstoptolistentotheirteacher.学生们停下来去听他们老师讲话。2.stopdoingsth意为“停止做某事”。如：Thestudentsstoppedtalking.学生们停止了谈话。与它们相反的句式是：goontodosth“继续做某事（与刚才一事不同）”和goondoingsth“继续做某事（与刚才同一件事）”。如：HefinisheshishomeworkandgoesontostudyEnglish.他完成了作业，接着继续去念英语。Theywentonplayinggames.他们继续玩游戏。-初二英语17单元复习要点1.Welcome
