1Unit1What’sthematter?单元语法讲解情态动词should的用法情态动词should和can，may，must一样，没有人称和数的变化，有词意，但都不能单独作谓语，必须和后面的动词原形一起构成谓语。基本意思是“应当，应该”，常用来表示建议或命令等。如：Youshouldworkharder.你应该更努力地工作。否定式和疑问式的构成与can，may，must一样。如：Youshouldn’tplaysoccerinthestreet.你们不应该在街上踢足球。Whoshouldpaythetaxidriver?谁应该付出租车钱？注意：常用句型Youshould/shouldn’tdosth.表示“建议某人（不）做某事”。其他表示“建议”的句型还有：Whynotdosth.?/Whydon’tyoudosth.?/Howaboutdoingsth.?/Whataboutdoingsth.?/It’sagoodideatodosth./You’dbetterdosth.等。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2如：Weshouldarrivebysuppertime.我们在晚饭前就能到了。Sheshouldbehereanymoment.她随时都可能来。1.We_________keepthenewtrafficlaw(交通法).A.mayB.shouldC.canD.need【答案】选B。2.I’dliketobuyanewshirt,butIdon’tknow__________.A.wherecouldbuyitB.IshouldtakewhichC.whichIshouldtakeD.wherecanIgetit【答案】选C。写出同义表达Whynothavearest?(1)Why_______________havearest?(2)You’d__________________arest.(3)You_______________arest.(4)_________________havingarest?【答案】(1)don’tyou(2)betterhave(3)shouldhave(4)Whatabout情态动词Should的用法练习题1.Iwasreallyanxiousaboutyou.You_______homewithoutaword.A.mustn'tleaveB.shouldn'thaveleftC.needn'tleaveD.couldn'thaveleft2.I'mnotfeelingwellinthestomach,I_______somuchfriedchickenjustnow.A.shouldn'teatB.mustn'thaveeatenC.mustn'teatD.shouldn'thaveeaten3.We_______lastnight,butwewenttotheconcertinstead.A.musthavestudiedB.mightstudy3C.shouldhavestudiedD.wouldstudy4.ItoldSallyhowtogethere,butperhapsI_______itoutforher.A.hadtowriteB.musthavewrittenC.shouldhavewrittenD.oughttowrite5.Thatyoungmanhasmadesomuchnoisethathe_______nothavebeenallowedtoattendtheconcert.A.couldB.mustC.wouldD.should6.It'snearlyseveno'clock.Jack_______behereatanymoment.A.mustB.needC.shouldD.can7.-WhencanIcomeforthephotos?Ineedthemtomorrowafternoon.-They_______bereadyby12:00.A.canB.shouldC.mightD.need8.Mary_______beinParis,forIsawherinthetownafewminutesago.A.mustn'tB.can'tC.shouldn'tD.maynot9.-Ididn'tseeherinthemeetingroomthismorning.-She_______havespokenatthemeeting.A.mustn'tB.shouldn'tC.needn'tD.couldn't10.-Therewerealreadyfivepeopleinthecar，buttheymanagedtotakemeaswell.-It_______acomfortablejourney.A.can'tbeB.mustn'thavebeenC.shouldn'tD.couldn'thavebeen11.Ifonlyhe_______quietlyasthedoctorinstructed,hewouldnotsuffersomuchnow.A.liesB.layC.hadlainD.shouldlie12.It'shardformetoimaginewhatIwouldbedoingtodayifI_______inlove,attheageofseven,withtheMelindaCoxLibraryinmyhometown.A.wouldn'thavefallenB.hadnotfallenC.shouldfallD.weretofall13.Johnny,you_______playwiththeknife,you_______hurtyourself.A.won't;can'tB.mustn't;may4C.shouldn't;mustD.can't;shouldn't14.-AreyoucomingtoJeff'sparty?-I'mnotsure.I_______gototheconcertinstead.A.mustB.wouldC.shouldD.might15.Aleft-luggageofficeisaplacewherebags_______beleftforashorttime,especiallyatarailwaystation.A.shouldB.canC.mustD.will.5反身代词1.概念:表示一个动作返回到该动作执行者本身或强调某人或某物“本人,本身”的代词叫作反身代词。2.反身代词形式形式第一人称第二人称第三人称单数myselfyourselfhimself，heself，itself复数ourselvesyourselvesthemselves3.用法:Pleasehelpyourselftosometea.Thegirlistooyoungtolookafterherself.Heneverthoughtofhimself.TheyteachthemselvesEnglish.*在句中做名词或代词的同位语,用来加强名词或代词的语气,做“亲自，本人”解,可以放在名词,代词之后,也可以放在句尾。Youyourselfsaidso.Thedeskitselfisnotheavy.Wediditourselves.=Weourselvesdidit.*做表语Tomisnotquitehimselftoday.Tom今天感到不适/舒服.常见短语beoneself身体健康；enjoyoneself玩得快乐；helponeselfto随便吃;随便用；擅自拿；talktooneself自言自语；teachoneself自学；=learnbyoneselfbyoneself单独地；foroneself为自己；反身代词练习题一、单项选择1.Thosegirlsenjoyed____inthepartylastnight.A.themB.theyC.themselvesD.herself62.Help____tosomefish,children.A.yourselfB.yourC.yoursD.yourselves3.Thefilm____isveryfun.A.it’sB.itselfC.itD.its4.–Whoteaches____math?–Iteach______.A.your,myselfB.you,myselfC.you,meD.you,herself5.Thefatherwillmake____abike____.A.her,himselfB.she,himselfC.her,herselfD.she,herself6.Thescarfis____,shemadeit_____.A.herself,herB.herself,hersC.hers,herselfD.her,herself7.LiuHulan’sdeathwasgreat.Shethoughtmoreofothersthan______.A.herB.sheC.hersD.herself8.Luckily,hedidn’thurt____terriblyyesterday.A.himB.themselvesC.himselfD.they9.Ican’tmendmyshoe_____.Canyoumenditfor?A.myself,meB.myself,IC.me,ID.I,me10.Ilikewatchinginthemirror.A.meB.IC.myD.myself11.Mr.MorehasmoremoneythanMr.Little.Buthedoesn’tenjoy_______.A.heB.himC.hisD.himself12.Lilywas9yearsold._____wasoldenoughtogotoschool________.A.She,sheB.She,herselfC.Her,herselfD.Her.she13.Jim’swatchismuchnewerthan_________.A.hersB.sheC.herD.herself14.Wouldyoulike_____forsuper?A:somethingChineseB：ChinesesomethingC:anythingChineseD:Chineseanything15.______pianoistooold,butshestilllikedplayingit.A.SheB.She’sC.HersD.Her16.—WhotaughtyouEnglishlastyear?7—Nobodytaughtme.Itaught______.A.meB.myselfC.mineD.I17.Thatbikeis_________?A．heB.himC.hisD.it18.Webought______apresent,but_______didn’tlikeit.A.they,themB.them,theyCthey,theirDtheir,they19.Mr.Morehasmore
