系動詞表語從句▲句子或主謂結構做表語（而不是某個具體單詞做表語），這個句子就是表語從句。像這樣含有兩個及以上主謂結構的句子，并且其中一個句子在另一個句子中充當了成分，這樣的句子就叫做復合句。指出句子成分〖合作探究〗指出表語從句部分：Hehasbecomewhathewantedtobetenyearsago.2.ShehasremainedwhereIstoodyesterdayforanhour.3.Hissuggestionisthatweshouldstaycalm.4.Thequestioniswhenhecanarriveatthehotel.Hehasbecomewhat

hewantedtobetenyearsago.2.ShehasremainedwhereIstoodyesterdayforanhour.3.Hissuggestionisthat

weshouldstaycalm.4.Thequestioniswhen

hecanarriveatthehotel.一、表語從句定義：

表語從句是在復合句中作表語的名詞性從句,放在系動詞之后,一般結構是“主語+系動詞+表語從句”。作用:對主語進行解釋說明。例句：1）Theproblemisthatmillionsofpeopledieofillnessescausedbysmoking.2）ThequestionremainswhetherwecanwinClass3.

二、引導表語從句的連接詞由從屬連詞that

引導的表語從句由連接代詞Who,whom,whose,which,what

和連接副詞where,how,why,when引導的表語從句由從屬連詞whether，asif引導表語從句由從屬連詞because,why引導表語從句e.g.WhatIwanttosayis

that

I’msorry.2.Thefactisthat

Iearnedmypassagebyworkingasanunpaidhand.（一）由從屬連詞that引導的表語從句that在從句中不充當任何成分，本身也沒有任何意義。只是起連接作用。

注：that在引導表語從句時不能省略。（二）由從屬連詞whether引導的表語從句1.Thequestionis______________________2.Thequestionis_______________________whetheritisworthdoing.whetherwecanwinthem.whether在句子中不充當任何成分，但具有“是否”的意義，表示對陳述的事物不明確或不清楚。此時不能用if，因為if不能引導表語從句。Thequestionis________wewillhaveoursportsmeetnextweek.A.thatB.ifC.whenD.whether注意點1：if不能引導表語從句Dasif/though引導表語從句時，在句子中也不充當任何成分，但有意義。譯為：似乎，好像。Helooks

asifhewerearichman.Itsoundsasifsomeoneisknockingatthedoor.他看起來好像是個富翁。聽起來好像有人在敲門。（三）由從屬連詞asif/through引導的表語從句LiLeiisnowinanewjacket.Helooksasifhewere

anAmericanboy.Thegirlisgivingusavividdescriptionofthemoon.Itseemsasifshehadbeentothemoonmanytimes.asif/through

引導表語從句時要注意語氣.若與事實相符，要用陳述語氣。若從句表示與現在事實相反,謂動用

；與過去事實相反用

.考試中?？疾檫@種虛擬語氣，不考查陳述語氣。一般過去式（be用were）had+done.這類詞引出表語從句時，與它們引出賓語從句一樣，要在從句中充當句子成分（一般充當主語、賓語、表語或狀語），并具有一定的意義，不可省略。what譯為什么或??????的人或事；其它連接詞的意義及充當的成分與它們在疑問句中作用一致。(四）連接代詞Who,whom,whose,which,what及連接副詞where,how,why,when引導的表語從句(2)Theproblemiswhowecangettoreplaceher.(3)Thequestionishowhedidit.(4)Thatiswherehewasborn.問題是我們能找到誰去替換她呢。問題是他如何做此事的。那就是他出生的地方。(1)Thatiswhatheisworriedabout.

那就是他擔心的事(1)That’sbecausehedidn’tunderstandme.(2)It’swhyhegotangrywithme.那是因為他不理解我。那正是他對我生氣的原因。(強調原因）（強調結果）（五）由從屬連詞because,why引導的表語從句1、句型：That/Itis/wasbecause……That/Itis/waswhy……

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

(1)Thereasonwhyhewaslateisthathewasill.他遲到的理由是他病了。why引導定語從句注意：

主句主語為reason,只能用that引導表語從句，不可用because.(2)It’swhyhegotangrywithme.那正是他對我生氣的原因。why引導表語從句1.Thereasonwhyhefailedis________hewastoocareless.A.becauseB.thatC.forD.becauseof2.Thisis___Sarawaslateforthemeeting.A.whyB.whatC.howD.That3.Thereasonis___heisunabletooperatethemachine.A.becauseB.whyC.thatD.Whether
