人教版九年级英语第三单元复习

ReviewofunitthreeTeenagersshouldbeallowedtochoosetheirownclothes.WrittenbyLinGengxiu1、主动语态和被动语态英语动词有两种语态，一种是主动语态，另一种是被动语态。主动语态的主语是动作的执行者，相当于语文中的一般句子。被动语态的主语是动作的承受者，相当于语文中的被动句。被动语态的基本时态有过去，现在，将来，和完成时。我们本单元主要学习的是它的一种特殊形式。它叫做含情态动词的被动语态。2、含情态动词的被动语态它的构成如下：动作的承受者+情态动词+助动词be+及物动词的过去分词+by+动作的执行者。（当我们不知道谁是执行者或没有必要指出时可以省略）Flowersshouldbewateredbyuseveryday.Classroommustbecleaned.3、allow的用法allowsbtodosth允许某人做某事=letsbdoMyteacherallowmetodiscusswithmypartnerinclass.beallowedtodosth被允许做某事weshouldbeallowedtogooutwithourfriendsonweekend.4、stop的用法归纳stoptodosth停下来去做某事Wealltried,stoptohavearest.stopdoingsth停止做某事Stoptalking,listentome,please！stopsbfromdoingsth阻止某人做某事、Myteacherstopsmefromthinking.canˊtstopdoingsth禁不住做某事Hecanˊtstopeatingduringtheparty.5、seem的句型sb.seemtodosth.某人看起来似乎要做某事。Heseemstofeelsad.itseemsthat+从句，看起来似乎怎么样。6、倒装句由so＋助动词(be/do/will/have)/情态动词＋主语　意为：…也是一样（前后主语不一致）　　Sheisastudent.SoamI.　她是一个学生，我也是。Shewenttoschooljustnow.SodidI.她刚才去学校了，我也是so+主语+助动词某人的确如此(前后主语一致)SheisgoodatEnglish.Soshedoes.她很擅长英语，她的确如此。.7、up的短语总结stayup熬夜getup起床cleanup打扫stayathome呆在家8、关于考试的短语takethetest参加考试passthetest通过考试failatest考试失败Finishatest完成考试9、短语小结insteadof代替concentrateon全神贯注atpresent目前，现在oldpeople’shome养老院intheway挡道的careabout担心关心=worryaboutatleast至少makeadecision做决定10.学习的短语总结Learnsthfromsb向某人学习具体的知识Ilearnmusicfrommyteacher.learnfromsb向某人学习品德，情操，精神等，抽象的WeshouldlearnfromLeiFeng.study侧重于学习过程，较高的较深的研究learn侧重于学习结果，模仿别人等学习学会。11、keepsb/sth.＋形容词　使某人/某物保持….　Weshouldkeepourhandcleaneveryday.12、both….and…两者都Bothyouandmearegoodchildren.13、begoodfor+doingsth/n和bebadfor+doingsth相反ReadingbooksisgoodforstudyingChinese.Readingbookonthebedisbadforoureyes.14、关于有机会做某事的表达haveanopportunitytodosth.=haveachanceofdoingsth.有机会做某事Ihaveanopportunitytotakepartinthisrace=Ihaveachanceoftakingpartinthisrace.14、花费用法sth.take(sb.)timetodosth.Ittook(me)10daystoreadthebook.sth.cost(sb.)……Thebookcost(me)100yuan.sb.spend…onsth.Shespent10daysonthisbook.sb.spend…doingsth.Shespent10daysreadingthisbook.sb.pay…forsth.15、serious的用法对…热衷，对…兴趣beseriousaboutdoing如：Sheisseriousaboutdancing.她对跳舞热衷。beseriousaboutsth.如：Sheisseriousabouthim.她对他感兴趣。16、成功的词性区别successn.不可数名词翻译为成功。可数名词翻译为成功的人或事情Successgiveshimolotofthings.succeedv.成功，达到，完成Ifyouworkhard,youwillsuccessinfuture.successfuladj.成功的Heisasuccessfulbusinessman.successfullyadv.成功地17、连词用法总结either…or…或者…或者IthinksheiseitherEnglishorChinese.notonly….butalso…不仅…而且…Sheisnotonlysmartbutalsobeautiful.neither…nor…既不…也不…Ineitherknownorcarewhathavehappenedtohim.
