系动词表语从句▲句子或主谓结构做表语（而不是某个具体单词做表语），这个句子就是表语从句。像这样含有两个及以上主谓结构的句子，并且其中一个句子在另一个句子中充当了成分，这样的句子就叫做复合句。指出句子成分〖合作探究〗指出表语从句部分：Hehasbecomewhathewantedtobetenyearsago.2.ShehasremainedwhereIstoodyesterdayforanhour.3.Hissuggestionisthatweshouldstaycalm.4.Thequestioniswhenhecanarriveatthehotel.Hehasbecomewhat

hewantedtobetenyearsago.2.ShehasremainedwhereIstoodyesterdayforanhour.3.Hissuggestionisthat

weshouldstaycalm.4.Thequestioniswhen

hecanarriveatthehotel.一、表语从句定义：

表语从句是在复合句中作表语的名词性从句,放在系动词之后,一般结构是“主语+系动词+表语从句”。作用:对主语进行解释说明。例句：1）Theproblemisthatmillionsofpeopledieofillnessescausedbysmoking.2）ThequestionremainswhetherwecanwinClass3.

二、引导表语从句的连接词由从属连词that

引导的表语从句由连接代词Who,whom,whose,which,what

和连接副词where,how,why,when引导的表语从句由从属连词whether，asif引导表语从句由从属连词because,why引导表语从句e.g.WhatIwanttosayis

that

I’msorry.2.Thefactisthat

Iearnedmypassagebyworkingasanunpaidhand.（一）由从属连词that引导的表语从句that在从句中不充当任何成分，本身也没有任何意义。只是起连接作用。

注：that在引导表语从句时不能省略。（二）由从属连词whether引导的表语从句1.Thequestionis______________________2.Thequestionis_______________________whetheritisworthdoing.whetherwecanwinthem.whether在句子中不充当任何成分，但具有“是否”的意义，表示对陈述的事物不明确或不清楚。此时不能用if，因为if不能引导表语从句。Thequestionis________wewillhaveoursportsmeetnextweek.A.thatB.ifC.whenD.whether注意点1：if不能引导表语从句Dasif/though引导表语从句时，在句子中也不充当任何成分，但有意义。译为：似乎，好像。Helooks

asifhewerearichman.Itsoundsasifsomeoneisknockingatthedoor.他看起来好像是个富翁。听起来好像有人在敲门。（三）由从属连词asif/through引导的表语从句LiLeiisnowinanewjacket.Helooksasifhewere

anAmericanboy.Thegirlisgivingusavividdescriptionofthemoon.Itseemsasifshehadbeentothemoonmanytimes.asif/through

引导表语从句时要注意语气.若与事实相符，要用陈述语气。若从句表示与现在事实相反,谓动用

；与过去事实相反用

.考试中常考查这种虚拟语气，不考查陈述语气。一般过去式（be用were）had+done.这类词引出表语从句时，与它们引出宾语从句一样，要在从句中充当句子成分（一般充当主语、宾语、表语或状语），并具有一定的意义，不可省略。what译为什么或••••••的人或事；其它连接词的意义及充当的成分与它们在疑问句中作用一致。(四）连接代词Who,whom,whose,which,what及连接副词where,how,why,when引导的表语从句(2)Theproblemiswhowecangettoreplaceher.(3)Thequestionishowhedidit.(4)Thatiswherehewasborn.问题是我们能找到谁去替换她呢。问题是他如何做此事的。那就是他出生的地方。(1)Thatiswhatheisworriedabout.

那就是他担心的事(1)That’sbecausehedidn’tunderstandme.(2)It’swhyhegotangrywithme.那是因为他不理解我。那正是他对我生气的原因。(强调原因）（强调结果）（五）由从属连词because,why引导的表语从句1、句型：That/Itis/wasbecause……That/Itis/waswhy……

2、句型：thereasonwhy……isthat……That/Itis/waswhy……

(1)Thereasonwhyhewaslateisthathewasill.他迟到的理由是他病了。why引导定语从句注意：

主句主语为reason,只能用that引导表语从句，不可用because.(2)It’swhyhegotangrywithme.那正是他对我生气的原因。why引导表语从句1.Thereasonwhyhefailedis________hewastoocareless.A.becauseB.thatC.forD.becauseof2.Thisis___Sarawaslateforthemeeting.A.whyB.whatC.howD.That3.Thereasonis___heisunabletooperatethemachine.A.becauseB.whyC.thatD.Whether

C

A表语从句的语序不管是哪类连接词引导，一律用陈述语序：主语+系动词+连接词+主语+谓语+其他成分三、表语从句语序注意：如果从句是特殊疑问句，要用陈述句语序Theproblemis_________totaketheplaceofJohn.A.whocanwegetB.whatwecangetC.whowecangetD.thatwecangetCItiswherehelivesin.Itiswherehelivedin10yearsago.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。三、表语从句时态2.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）Herwishwasthatshecouldloseweightsoon.Itlookedasifitwasgoingtorain.Thequestionwaswhetherhisfatherwouldcomebackthenextday.Thereasonwhyhewaslatewasthatthetrainhadalreadyleft.小结：1.表语从句的构成:引导词+简单句2.引导词:连词that,whether,asif连接代词who,what,which连词because,why

3.语序:时态呼应一致原则4.时态:陈述语序连接副词when,where,
