isobviousthattheaccidentwascusedbydrunkdriving.3.It+不及物动词+that从句

Itseems/appears...that...似乎…… Ithappened(tosb.)that...碰巧……IthappenedthatIwasonthespot.Itseemsthatwewon'thaveaholidayuntilJune6th.4.Itis/was+v-ed+主语从句Itissaid/reported/believed/ suggested/well-known/provedthat...Itisreportedthatmorethanthirtydeathswerecausedintheaccident.Practice(同步测评P86)【要点精讲】1.what与that引导主语从句 观察下列例句，试着翻译例句并总结 其规律。(1)Whatyoulackisself-confidence.译为：_________________________你所缺乏的是自信。(2)Thatmoreandmorestudentsare admittedintouniversitiesistrue.译为：______________________________________________________(3)Whatisneededfortheprogramis morewisdom.译为：_____________________________这个项目所需要的是更多的智慧。越来越多的学生将被大学录取的消息是真实的。从上面例句可以看出，that引导主语从句时，在句中具有“两不”原则：一、不作句子成分；二、没有实际意义。当它引导的主语从句置于句首时，that不能省略；如果用it作形式主语，而把主语从句放在句末时，that可以省略。而what引导的从句则恰恰相反，what在从句中的作用为：一、作句子成分；二、除了起到引导从句的作用外还要承担具体的意义。【巩固练习】

用what或that填空。(1)_____hetoldusthismorningwas justalie.(2)_____isimportanttousisenough time.(3)Itworriesmymom_____sheis beginningtogetalittlefat.(4)_____wecan’tgetseemsbetterthan _____wehave.WhatWhatthatWhatwhat2.whether与if引导主语从句whether与if引导主语从句位于句中有时可换用。但在下列情况下用whether不用if：(1)主语从句位于句首时；(2)从句后有or或紧跟ornot时。【巩固练习】

用whether或if填空。(1)Itdoesn’tmatter___________hewill comeornot.(2)________we’llgocampingtomorrow dependsontheweather.(3)Itwasdoubtful___________Tom reallysawSharon.(4)________TomreallysawSharonwas doubtful.whether/ifWhetherwhether/ifWhether3.其它引导词连接代词who,which,whom,whose有各自的具体意义，起连接作用，同时在从句中充当主语、宾语、表语、定语等；whoever,whatever,whichever在意义上更为强调，常译为“无论……”；连接副词when,where,why,how等也有各自的意义，起连接作用，并在从句中作状语。【常见错误展示】下列各句均有一处错误，请改正并分析错误的原因。1.Lighttravelsfasterthansoundiscommonknowledge.Thatthat虽无词义但引导主语从句位于句首时不能省略。if,whether都可表示“是否”,但if不能引导句首主语从句。2.Ifshe’scomingornotdoesn’tmattermuch.Whethershe’scomingornotdoesn’t3.Whatwereyourproblemsayear agohasnowbecomemine.has要改为have。主语从句表示复数概念时，谓语要用复数形式。have4.Thattheprofessorsaidisofgreatimportance.5.Wherewillthetreesbeplantedhas notbeendecided.Whatthat引导主语从句时无词义。Whattheprofessorsaid表示“教授所说的”。将will置于trees之后。主语从句要用陈述句语序。6.Nomatterwhobreakstherulewill bepunished.7.Whenandwherethemeetingwillbe heldstillremainaquestion.引导让步状语从句时二者可互换，但引导名词性从句时只能用whoever。Whoever主语从句表示单一概念时，谓语要用单数形式。remains5.StephenHawkingat65experiencedzerogravityduringaflight.Itamazedeverybody.6.Plutoisnolongerconsideredaplanetinoursolarsystem.Whatasurprise!ItamazedeverybodythatStephenHawkingat65experiencedzerogravityduringaflight.ItisasurprisethatPlutoisnolongerconsideredaplanetinoursolarsystem.Alloflifeisanactoflettinggo,butwhathurtsthemostisnottakingamomenttosaygoodbye.人生就是不断地放下，但最令人痛心的是，我们来不及好好告别。Linefromthefilm‘LifeofPi’Enjoymoreclausesusedasthesubject.subjectclauseIt’srarethatIfindsomeonesonon-patronizing.Linefromthefilm‘Zootopia’subjectclauseWhatpainsustrainsus.Whatdoesn’tkillusmakesusstronger.Whathurtsusthemostteachesusthebest.使我们痛苦的东西在真正锻造我们。没有要我们命的事情让我们更强大。伤害我们最深的教会我们最多。subjectclauses用适当的连接词补全下面的对话。Lucy:Whyareyoulookingsohappy?Jenny:I’vejustattendedalecture.________thespeakersaidmademeexcited.Lucy:Whatwasitabout?Jenny:Abouthealth.Itseems______alotofpeopledon’tknowhowtokeephealthy.What
