(教材P5)◆表语从句的概念●表语从句在复合句中作主句的表语。表语从句和主语指同一内容，是对主语进行的解释和说明，使主语的内容具体化，请观察下面的句子Thetruthisthatheisthethief事实上他就是小偷

(这里，表语从句是对主句主语

truth的说明表语放在系动词is之后,从属连词that引导表语从句)◆表语从句的表现形式

●由连词whether和that引导表语从句，常用句型:

Thereasonisthat….原因是……Theproblemiswhether….问题是是否….Thetroubleisthat…..麻烦在于….请观察以下句子a.Theproblemiswhetherweshouldaskthemforhelp.

问题是我们是否请他们帮忙b.Thetroubleisthathehasneverdonetheworkbefore.麻烦在于他以前从未做过这个工作c.Thereasonisthathehasoftenlied.原因是他经常说谎d.Theirwonderiswhetherhewillattendthemeeting.※悄悄告诉你：that虽然在其引导的表语从句中无实际意义，也不充当句子成分，但一般不可省略；whether意思是“是否”，在句中不充当句子成分，不可省略;if也有“是否”之意，但不能引导表语从句●

动词跟表语从句的用法Itappearsthat...似乎....Itseemsthat….好像......Itturns/turnedoutthat...结果….;证明是….Ithappensthat...恰好….请观察以下句子a.Itappearsthathewillwintheprize.看起来他会得奖b.Itseemsthatheislying.看样子他好像是在撒谎c.Itturnedoutthattwotravelershadbeenkilled.后来证实有两位旅客丧生●
