总是现在时Thatis表示性质Thatwas指过去动作固定句型:Thisiswhere…Thisiswhy…Thisishow….这就是…的地方这就是…的原因这就是…的方法\n试区分以下句子Isthismuseumwhatyouvisited?Isthisthemuseumthatyouvisited?Isthismuseumtheonethatyouvisited?注意：这种句子考试时一定要记住这句话：名词前（尤其是单数可数名词前）一定要有限定词。然后把句子变换成陈述句，接着判断句子是属于哪种从句再完成。(表从)(定从)(定从)\nII表语从句在句中充当表语的从句(即放在be动词后面)叫做表语从句。我们的目的是他能认识到错误。Ourpurposeisthathecanrealizehisfaults.注意：引导表语从句的连接词一般不省略。问题是它是否值得做。Thequestioniswhetheritisworthdoing.注意：表语从句表示“是否”只用“whether”而不用“if”\n2.1引导表语从句的关联词引导表语从句的关联词与引导主语从句的关联词大致一样，表语从句位于连系动词后，有时用asif引导。其基本结构为：主语+系动词+that从句，引导表语从句的词有that，whether，who，what，which，whoever，whatever，whichever，when，where，why，how，because等。\n(1)that,whether引导的表语从句that在引导表语从句时无词义，不做成分，而whether有词义，意为、“是否”,不做成分。这时主句的主语常常是些抽象名词,如question,trouble,problem,result,chance,suggestion，idea，reason等。eg:Thereasonisthatyoudon’ttrusther.Thequestioniswhethertheywillbeabletohelpus.问题是他们是否能帮我们。\n(2)连接代词引导的表语从句连接代词what,who,whom,which,whose,whatever,whoever,whomever,whichever在句中作主语/宾语，不能省略。eg:Theproblemiswhocanreplaceher.问题是我们能找到谁去替换她呢。That'swhatheisworryingabout.那就是他在担心的事。\n(3)连接副词引导的表语从句连接副词where,when,how,why在表语从句中做状语Thequestionishowhedidit.问题是他是如何做此事的。\n(4)连词because,asif,asthoughHewaslatethismorning.Thatwasbecausehewascaughtinatrafficjam.Allthiswasovertwentyyearsago,butit’sasifitwasonlyyesterday.这都是20多年前的事了，但宛如昨天一样。Helookedjustashehadlookedtenyearsbefore.他看起来还与十年前一样。注：从属连词if一般不用来引导表语从句，但asif却可引导表语从句，能跟表语从句的谓语动词一般为系动词be,seem,look等。Itlookedasifitwasgoingtorain.看起来天要下雨了。\n难点1.连词because可引导表语从句。如：eg:Ithinkitisbecauseyouaredoingtoomuch.我想这是因为你做得太多。2.引导表语从句的that不省略，that仅起连接作用，在从句中不充当任何成分，无任何意义。eg:Theimpressionhemakesonmeisthatheisareliableperson.他给我的印象是他是一个可靠的人3.whether可引导表语从句，表“是否”，它在从句中不充当成分，if不能引导表语从句。eg:WhetherJohnwilldothisexperimentremainsaquestion.\n4.thereason后面的表语从句只能用that引导，易犯“thereasonisbecause…”的错误eg:Thereasonwhyhewaslatewasthathiscarbrokedownontheway.5.在表示命令order,advice,suggestion,desire,proposal,demand,request,requirement等的名词后的表语从句中，谓语动词要用虚拟语气：should+动词原形，should可省略eg:Hissuggestionisthatwe(should)holdanothermeetingtodiscusstheproblem.\n最具代表性的表语从句1.ThatiswhypracticeisthemostimportantinlearningEnglish.2.Thevillageisnolongerwhatitusedtobetenyearsago.3.Thatwasbecausehewascaughtinatrafficjam.4.Thereasonwhyhewaslatewasthathiscarbrokedownontheway.\nIknowhim.2.Iknowwhoheis.主语谓语宾语（简单句）主语谓语宾语从句连词从句主语从句谓语主句复合句\nIII.宾语从句在句中充当及物动词或介词或某些形容词的宾语的句子叫做宾语从句。通常放在主句谓语动词(及物动词)或介词或形容词之后。1.Ithinkthatitwillbeofnouse.2.Iwonderifyoucandomeafavour.3.Itdependsonwhetherthebosswillagreetoyouornot.4.I’msurethatyouwillwinthegame.\n1.作动词的宾语(1)动词后直接+宾语从句由that引导的宾语从句(that通常可以省略),例如：Iheardthathejoinedthearmy.由what,whether(if)引导的宾语从句，例如：Shedidnotknowwhathadhappened.Iwonderwhetheryoucanchangethisnoteforme.(2)动词＋间接宾语＋宾语从句。例如：Shetoldmethatshewouldacceptmyinvitation.\n3.作形容词的宾语Iamafraid(that)I’vemadeamistake.Iamsure(that)hewillwinthegame.2.作介词的宾语Idon'tcareforwhomarrieshim.Wearetalkingaboutwhetherweadmitstudentsintoourclub.\n宾语从句三要素：连接词时态语序\n3.1引导词由从属连词that引导的宾语从句连接代词Who,whom,whose,whichwhat连接副词where,how,why,when引导的宾语从句由从属连词whether,if引导的宾语从句\n由从属连词that引导的宾语从句注：that在句中无词汇意义，在从句中不能充当成分，在口语或非正式文体中往往省略e.g.Ihear(that)_______________________.（一小时后他会回来）Hesaid(that)______________________.（他非常想念我们）Theteachertoldus(that)___________________________.（地球围着太阳转）hewillbebackinanhourhemissedusverymuchtheearthmovesaroundthesun\n由从属连词whether,if引导的宾语从句e.g.1.Iwanttoknow__________________________________.（他是否跟我们一起去公园）2.Askhim_____________________.（他是否能来）3.Idon’tknow___________________________.（是否要下雨）if(whether)hewillgototheparkwithuswhether(if)hecancomewhetheritisgoingtorainornotwhether,if在从句中不能充当成分，当句末为ornot时，引导词只能用whether而不能用if.\n由连接代词what,whom,whose,which,what连接副词when,where,how,why引导的宾语从句1.Heasked__________________________.(谁能回答这个问题）2.Doyouknow_________________________.（他们在等谁）3.Heasked__________________________________.（谁的书法是班上最好的）※5.6.Pleasetellme_______________________.（我们什么时候开会）7.Canyoutellme_______________.（他在哪儿）8.Couldyoutellme______________________.（我该怎么去车站）9.Wouldyoutellme_________________（为什么火车迟到了）whocouldanswerthequestionwhomtheyarewaitingforwhosehandwritingwasthebestintheclasswhenwe’llhaveameetingwhereheishowIcangettothestationwhythetrainislate\n3.2语序宾语从句的语序用陈述语序：连接词+主语+谓语+其他成分\n主句时态从句时态一般现在时、一般将来时、祈使句时根据句意的需要用任意一种时态一般过去时与原句相对应的过去的时态客观事实、真理、自然现象、名言警句、谚语等一律用一般现在时3.3时态\nIknowheliveshere.Iknowhelivedheretenyearsago.Ihaveheardthathewillcometomorrow.主句用现在时或将来时，从句可用任何时态，根据实际情况而定。\n2.如果主句是过去的时态（一般过去时，过去进行时），从句的时态一定要用相对应的过去的某种时态（一般过去时，过去进行时，过去将来时，过去完成时）Iknewwholivedhere.Isawshewastalkingwithhermother.Heaskedwhetherhisfatherwouldcomebacktomorrow.Hesaidthathehadseenit.\nTheteachertoldmeshewasbornin1960.IheardthathewenttoParislastnight.3.从句说明的是一般真理、客观事实、自然现象时，仍用一般现在时。Dadtoldusthatitisbettertodothantosay.Hetoldtheboythatthreeandthreeissix.Hetoldmetheearthmovesaroundthesun.4.从句中有具体时间状语，即使从句动作发生在主句动作前，仍用一般过去时。\nTheradiosaysit_______cloudytomorrow.(be)Theheadmasterhopeseverything______well.(go)Ihearthey__________(return)italready.Hesaidthatthey_________membersofthePartysince1948.(be)Ourteachertoldusinclas
