(教材P5)◆表語從句的概念●表語從句在復(fù)合句中作主句的表語。表語從句和主語指同一內(nèi)容，是對主語進行的解釋和說明，使主語的內(nèi)容具體化，請觀察下面的句子Thetruthisthatheisthethief事實上他就是小偷

(這里，表語從句是對主句主語

truth的說明表語放在系動詞is之后,從屬連詞that引導(dǎo)表語從句)◆表語從句的表現(xiàn)形式

●由連詞whether和that引導(dǎo)表語從句，常用句型:

Thereasonisthat….原因是……Theproblemiswhether….問題是是否….Thetroubleisthat…..麻煩在于….請觀察以下句子a.Theproblemiswhetherweshouldaskthemforhelp.

由連接代詞who,what,which引導(dǎo)的表語從句，請觀察以下句子a.Sheisnotwhatsheusedtobe.她不再是過去的那個她了b.WhatImeaniswhichsongyoulikebest.我的意思是你最喜歡哪首歌c.Thequestioniswhowillbesenttolookaftertheoldman.問題是派誰去照顧這個老人d.Thisiswhatthebosssaidatthemeeting.這就是老板在會上說的話e.Theproblemiswhichbooksareworthreadingforusall.問題是，對于我們所有人來說，那些書值得讀●由連接副詞(where,when,how,why)引導(dǎo)表語從句請觀察以下句子a.ThatiswhereChairmanMaousedtolive.那就是毛主席曾經(jīng)住過的地方b.Theproblemiswhentheywillarriveattheairport.問題是他們什么時候到達機場c.That'swhyhedidn'tpasstheexam.那就是他考試不及格的原因d.Sheworkstoohard.Thatiswhysheisexhausted.她工作太辛苦了，這是她筋疲力盡的原因e.Thisishowtheysolvetheproblem.這就是他們?nèi)绾谓鉀Q這個問題的a.Itlooksasifitweregoingtorain.天看上去好像要下雨b.Itlooksasthoughheiswillingtogothere.看起來他好像愿意去那里c.That'sbecausetwothirdsoftheearth'ssurfaceismadeupofvastoceans.那是因為地球表面的三分之二是由廣闊的海洋組成的d.Thereasonwhyshewaslateforworkisbecauseshewastrappedintrafficjam.她上班遲到的原因是遇上了交通阻塞●

由asif或asthough,because引導(dǎo)表語從句，請觀察以下句子◆

動詞跟表語從句的用法Itappearsthat...似乎....Itseemsthat….好像......Itturns/turnedoutthat...結(jié)果….;證明是….Ithappensthat...恰好….請觀察以下句子a.Itappearsthathewillwintheprize.看起來他會得獎b.Itseemsthatheislying.看樣子他好像是在撒謊c.Itturnedoutthattwotravelershadbeenkilled.后來證實有兩位旅客喪生●

be,seem,look,appear,turn/turnout,happen,remain等系動詞后均可跟表語從句,常見以下類似結(jié)構(gòu)d.Ithappenedthatthefamousactorwasherbrother.那個有名的演員恰好是她的哥哥e.Thefactremainsthatwearebehindtheotherclasses.事實是我們落后于其他班級f.Itseemsthatthesechildrenarereading.孩子們似乎在讀書g.Itappearsthatallthesoldiershavecomehere.好像所有的士兵都到了◆考點訓(xùn)練1.Thequestionis________wewillhaveoursportsmeetnextweek.A.that
