最少务必，确信.语法：神态动词一、神态动词的定义神态动词是一类用于表示说话人的语气和神态的助动词。常表示命令、恳求、拒绝、义务、可能、需要等。二、神态动词的特点1.神态动词无人称和数的变化,2.神态动词后边跟的动词需用原形,否认式组成是在神态动词后边加"not"。个别神态动词有过去式,过去式用来表达更客气,宛转的语气,时态性不强,可用于过去，现在。三、神态动词的用法1.can/could；can’t/couldn’t(否认)表示能力,意为“能、会”,比方：如：IcanspeakalittleEnglish.--Canyourideabike?Ican’tswim.--Yes,Ican./No,Ican’t.表示恳求或赞同，多用于口语中，意为“能够、能”等如：Youcangohomenow.现在你能够回家了--CanIborrowyourbike?Youcan’tstopyourcarhere.--Yes,youcan./No,youcan3)用于否认句、疑问句中，表示猜想、思疑或不用然.如：Lucycan’tbeathomenow,shewenttotheparkjustnow.Wherecanitbe?Ican’tfindmyfootball.

’t.【注意：】1）could是can的过去式,有两种用法语气,时态性不强,可用于过去，现在。

,一种表示过去式；一种用来表达更为客气

,宛转的2）

beableto

意为“有能力，能够做

...”,

相当于

can/could,

但它有人称，数和时态的变化。2.may;

maynot(否认)表示“恳求，赞同”，此时与can同义，能够交换使用如：MayIborrowyourbike?CanIborrowyourbike?Yes,youmay./No,youmaynot.Yes,youcan./No,youcan

’t.may/might表示不太必然的猜想，意为“有可能”如：Lucymaycometoschoollatetoday.Itmightraintoday.【注意】：might是may的过去式气的语气或对可能性的思疑。

,

有两种用法

,一种表示过去式，一种表示更为宛转

,客3.must;

mustn’t(否认)must(“必然”,表示命令)，mustn’t(“必然不能够”,表示强烈禁止...)如：Youmustgotobedbefore22:00pm.Youmustn’tplaywithfire.It’sdangerous!--MustIwritedownthesentences？--No，youneedn’t.(--No,youdon’thaveto)注意：在回答must的疑问句中，否认回答用needn’t或don’thaveto表示“不用”，不用mustn’tmust还能够够表示特别必然的猜想，意为“必然”如：ThegirlinaredskirtmustbeLucy.must/haveto的差别：①.must表示必然，重申主观上的梦想；haveto表示“不得不”，重申客观需要如：Youmustgobebedbefore22:00pm.Mybikeisbroken,soIhavetogotoschoolonfoot.②.haveto有人称、数、时态的变化；must则没有。如：Ihavetocleantheclassroomtoday.Shehastofinishherhomeworkfirst.Itwaslate,hehadtogotoschoolwithoutbreakfast.一，选择填空：()1.Mummakesmeeatanappleeveryday______thedoctoraway.A.keepsB.iskeptC.tokeepD.kept()2.I’mgettingfatterandfatternow.WhatshouldIdo,doctor?--You’dbettereatfoodandtakeexercise.A.less;lessB.more;moreC.more;lessD.less;more()3.---WhatcanIdoforyou?---I’dliketwo_______.A.packetofteaB.packetsofappleC.packetsofteaD.packetofapples()4.Watercomestoourflats__________pipesunderthestreets.A.acrossB.alongC.throughD.over()5.AndyWanglooks_________today.Heislaughingalltheway.A.happyB.happilyC.sadD.sadly()6.Thecomputerisconnected_______amachine.A.atB.toC.onD.in()7.Ourheadteacheriskindtousandsheislikeourmother,_____.A.onthewayB.bythewayC.inawayD.intheway()8.________youshowmethewaytothenearestundergroundstation?A.mayB.mustC.canDshould()9.Electricity__________ourlifeeasier,Wemustsaveit.A.makeB.makesC.ismakingD.made()10.Jasonputsomericeinthepotand__________thericecooker.A.openedB.switchedonC.closedD.turnedoff()11.Iwashedalotofclothes.Whocan_______?A.tidyupthemB.tidythemupC.tidyitupD.tidyupit()12.Iaskedhimtwice.Buthedidn’t______myquestions.A.answersB.answertoC.replyD.replyto()13.Thereare_________syllablesintheword“chemical”.A.twoB.threeC.fourD.eight()14.—Jon:MayIhaveapacketofsweets?—Shopassistant:________________A.No,itisnotyoursB.OK,hereyouareC.That’sagoodideaD.Whynot?( )15.EarthHourstartedin2007in________.A.theUSAB.ChinaC.theUKD.Australia二，用同义词（组）取代句中的划线部分。1．“Idon’tthinkitisagoodwaytoworkouttheproblem.”repliedMrWhite.A.saidB.answeredC.askedD.thought2.Don’tlooksofoolish.Itisaveryeasyquestion.A.sillyB.happyC.clever3.----CanIaskyouaquestion?----Waitforamoment,I’mcoming.A.alongtimeB.ashorttimeC.atonce4.Theboyislikehisfather.A.likesB.soundslikeC.lookslike5.Youneedn’tfinishtheworktoday.A.don’thavetoB.can’tC.mustn’t三，完形填空ElectricityElectricityisverydangerous.(1),itisalsovery(2)inaway.We(3)seeelectricity,butwecan(4)itintodifferent(5)ofenergy,（6）movementenergy,heatenergy,soundenergy,lightenergyandso(7).Electricityisaverygreat(8).Itchangesourlives.(9)it,ourliveswillbevery（10）.1.()A.OrB.AndC.ButD.So2.()A.hardlyB.usefulC.beautifulD.difficult3.()A.canB.mayC.maynotD.can’t4.()A.putB.getC.turnD.make5.()A.formB.fromC.fromsD.forms6.()A.likesB.suchasC.forexampleD.seem7.()A.atB.inC.onD.into8.()A.thingsB.inventionC.jobD.discoverment9.()A.OwnB.WithC.NoD.Without10.()A.easyB.beautifulC.difficultD.simple四，阅读理解AelectricmachineJane’smotherwasaboutseventy,soJaneandherhusbandwantedtogivetheoldladyanicepresentforherbirthday.Shelikeddrinkingtea,soJaneboughtasmallelectricmachineforher.Itcouldmaketeaandthenwakepeopleupinthemorning.Shebroughtittohermotheronherbirthday,andshowedherhowtouseit.Beforeyougotobed,putteaandwaterinit,”sheexplainedtohermother,”anddon’forgettoturnontheelectricity.Whenyouwakeupinthemorning,yourteawillbeready.Afterafewdays,theold”ladytelephonedherdaughterandsaid,”Jane,thereisonethingIdon’tunderstand.WhydoIhavetogotobedtomaketea?Can’tIhaveteaintheafternoonorintheevening?”1.()Onthebirthday,Jane’smorthergotamachineto.A.maketeaforherB.buyteaforherC.wakeherupinthemorningD.bothAandC2.()howtousethemachine.A.JanetoldherhusbandB.JanetoldhermotherC.Jane’husbandtoldhermotherD.Jane’smotherknew3.( )Themachinecanbeused.A.beforegoingtobedB.onlyinthemorningC.bothintheafternoonandeveningtime4.( )Weneedtouseanelectricmachine.A.timeB.atelephoneC.electricityD.tea5.( )Fromthepassageweknowthat.A.JaneisbeautifulB.Janehishusbandaresilly.C.JaneisagooddaughterD.Jane’smotherishard-working
