1Module12Saveourworld学习目标1、学会本单元重点单词和重点词组的运用2、语法知识点：前缀、后缀构词法重点知识点1.It’snousedoingsth.做某事是没有用的。himnottoworry.告诉他不要担心没有用。2、suchas例如，比如（用来列举同类人或物中的几个例子，as后面不可以有逗号）辨析：suchas与forexample的区别(1)suchas一般用来列举同类人或物中的几个例子,插在被列举的例子和前面的名词之间,as后没有逗号。(2)forexample一般只举同类人或物中的一个例子，作插入语，前后用逗号隔开，置于句首、句中、句末均可。3.hopeless无望的hopeless作形容词，由“hope+后缀-less”构成，意为“无望的”。归纳：常见的加后缀-less构成的形容词-less是形容词后缀，可加在一些名词之后，表示“无……，没有……”。careless粗心的useless无用的fearless无畏的homeless无家可归的4、somuch&somany那么多①somuch后接不可数名词②somany后接可数名词25、dowith对待；处理；应对=dealwith辨析：dowith与dealwith的区别①do是及物动词，后面可接宾语，因此dowith要与可作宾语的疑问代词what连用构成特殊疑问句。②deal是不及物动词，因此要与疑问副词how连用构成特殊疑问句Idon’tknowwhatthedowiththeproblem.=Idon’tknowhowtheydealwiththeproblem.我不知道他们如何处理这个问题。6、divide…into…把……分成……辨析：divide与separate的区别①divide指把整体划分为若干部分，被分开的对象在一定的条件下具有一定的统一性。例：Let’sdivideourselvesintoseveralgroups.我们分成几个小组吧②separate分离；隔离，常与form连用，表示“把……从……分离”，指把原来连在一起或靠近的各个部分分隔开来，被分隔的对象没有任何统一性。例：Willwantstoseparatehismusiccareerfromhismoviecareer.威尔想把自己的音乐事业和电影事业分开。7、beharmfulto…对……有害（to是介词，后接名词、代词或动名词）=doharmto8、change…into…把……变成……，使……变为……=turn…into…9、such&so的区别such修饰名词such+a/an+adj+单数名词+that从句such+不可数名词/复数名词+that从句so修饰形容词或副词so+adj+a/an+单数名词+that从句so+adj/adv+that从句当名词前有many、much、little、few修饰时，只用so修饰。例：somanypeople、somuchfood3【练习】（）1.Theyare______interestingnovels______Iwanttoreadthemonceagain.A.such,thatB.so,thatC.very,thatD.too,to（）2.--______finedayitistoday.--Yes,thesunshineis______beautifulthatI’dliketogotoswimminginthesea.A.How,suchB.Howa,soC.Whata,soD.What,so（）3.Thecamerais______expensive______Ican’taffordit.A.so,thatB.such,thatC.so,astoD.too,to（）4.Itis______aheavystone______Ican’tliftitup.A.so,thatB.such,thatC.too,toD.very,that（）5.There’re______manymistakesinhishomework______hemustreviewit.A.sucha,thatB.such,thatC.too,toD.so,that10.重点词组专项练习一、单项选择1.throwaway扔掉2.tonsof许多，很多3.begoodfor对...…有好处6.workout算出；解决；弄懂；锻炼7.turnoff关闭8.dowith处理9.findout查明，弄清楚10.lookafter照顾，照料11.divide…into把…...分成......12.payattentionto注意......13.spreadovercitiesandvillages遍及城市和乡村14.beadangerto对……有危险15.somany+可数名词复数这么多......somuch+不可数名词这么多……16.It’snouse/gooddoingsth.做某事是没用的17.niceidea=goodidea好主意18.saveenergy节约能源19.causepollution引发污染20.askforsb.找某人，求见某人askforsth.要某物asksb.forsth.向某人要某物21.beharmfultosb./sth.=doharmtosb./sth.对某人/某物有害doharmforsb.todosth.对某人来说做某事有害22.ifpossible=ifitispossible如果可能的话23.change...into...=turn...into...把......变成......24.tonsof大量的，许多的25.makeachange作出改变26.hopeforsth.期待/盼望某事27.takestepstodosth.采取措施做某事28.tryone’sbesttodosth.尽某人最大努力做某事29.protecttheenvironment保护环境30.cleanup打扫，清理4()1.Thechildrenarereadingbooks_______art.A.inB.onC.forD.by()2.Pollutionfromfactories_______overcitiesandvillages.It’saseriousproblem.A.spreadB.spendsC.speadedD.throw()3.Manyfisharedeadbecausetheriver_______.A.pollutesB.ispollutingC.ispollutedD.waspolluted()4.It’snouse_______meaboutit.Idon’tknow,either.A.talkB.totalkC.talksD.talking()5.Everyone_______torecyclethewasteatagreenschoolandathome.A.learnsB.learnC.learningD.learned()6.Ifyouwanttokeepfit,youcaneat_______anddomoreexercise.A.fewB.littleC.lessD.more()7.There’s_______homeworktoday.Hehastostayathome.A.somuchB.somanyC.toomanyD.muchtoo()8.It’sabadhabit_______papereverywhere.A.topickupB.tothrowawayC.cleanupD.clearup()9.______heisonly8yearsold,heknowsmoreaboutsciencethanhisfather.A.ButB.AlthoughC.SoD.Because()10.--Isthere______intoday’snewspaper?--No,thereisn’t.A.anythingnewB.somethingnewC.newsomethingD.newanything()11.It’slate.It’sbetterforus______abus.A.takeB.totakeC.istakingD.took()12.WeshouldspeakEnglish______possibleafterclass.A.AsmuchasB.asmoreasC.aslongasD.asmanyas()13.Hegotupveryearly______hecouldtaketheearlybusinthemorning.A.inordertoB.sothatC.suchasD.suchthat()14.Thebooksareveryhelpfulforme,______reading,writinganddrawing.A.suchB.suchasC.forexampleD.aswellas()15.Weproduce______rubbisheveryday,sowehavetomakeachange.A.tonofB.tonsofC.lotofD.alotsof二、完型填空。AyoungmanonceaskedAlbertEinstein,theGermanscientist,16thesecretofsuccess(成功的秘密)was.Thescientist17himthatthesecretofsuccesswashardwork.Afewdays18,theyoungmanaskedhimthe19questionagain.Einsteinwasveryangry.Hedidnotsay20,butwroteafewwordsonapieceofpaperand21ittotheyoungman.Theyoungmanlooked22thepieceofpaper.Onitwaswritten:A=X+Y+Z.What23thismean?askedtheyoungman.Ameanssuccess,245theoldscientist.Xstandsfor(代表)hardwork,Ystandsforgoodmethods(方法),andZ…Zmeans25talkingandstarttowork.16.A.whoB.whetherC.whatD.which17.A.toldB.saidC.repliedD.spoke18.A.agoB.beforeC.earlierD.later19.A.easyB.difficultC.differentD.same20.A.anythingB.somethingC.nothingD.everything21.A.tohandB.handC.handedD.handing22.A.onB.upC.downD.at23.A.willB.shallC.doesD.did24.A.saidB.thoughtC.believedD.laughed25.A.goonB.stopC.enjoyD.like三、阅读理解AArrivinginNewYorkTherearethreeairportsinNewYork.Whenyouarriveatoneofthem,youcantakeabusortaxitoanyplaceinNewYork.HotelsTherearelotsofgoodhotelsinNewYork.ThebestisThePlazaon5thAvenuebutyoudon'thavetopayalottostayinthecity;therearelotsofsmallerhotelsandtheYMCA(青年旅店)nearCentralParkisgreatforyoungpeople.EatingoutTherearemanykindsoffoodinNewYorkandy
