Predicative clause
表语从句：在复合句中作表语成分的从句
This is his jb.主+系+表This is what he des every day.
(1)that引导的表语从句that引导表语从句仅起连接作用，无意义，在句中不作任何成分，通常不能省略。这种从句往往对主句主语的内容起进一步解释的作用。The fact is that fish can't g withut water.事实是鱼离开水不能存活。

我只知道她曾在银行工作过。
关键是我们应该依靠自己。

②连接副词wh(ever),whm(ever),,whse,what(ever),when(ever), where(ever), hw(ever), which(ever),why除在句中起连接作用外，在从句中还充当时间、地点、方式或原因状语，本身具有词义。Their difficulty is where they can raise enugh mney.他们的困难是他们到哪里能筹到足够的钱。That is why they were late fr the meeting.那就是他们会议迟到的原因。

(3)whether引导的表语从句The questin remains whether they will be able t help us.[关键点拨]　if只能引导宾语从句，whether可引导宾语从句、表语从句、主语从句和同位语从句。
1.The questin is she’s wrried is abut is .

whse, which, what
when, where, why, hw
whether, because, as if, as thugh
(4)连词as if/thugh, because等引导的表语从句because引导表语从句通常只用于“This/That/It is/was because...”结构中。as if/thugh/like引导的表语从句常置于系动词lk, seem, sund, be, becme等后面，常用虚拟语气，也可用陈述语气。He lked just as if he had lked ten years befre.他看起来还与十年前一样。It lks as if it is ging t rain.天好像要下雨了。

cnclusin:当表语从句描述原因, 主句主语为reasn时，连接词用_______。because引导表语从句通常只用于_______________________ 结构中。总结句型为_________________________________________________________。
This/That/It is because
The reasn why ... was/ is that ...
(5)表语从句中的虚拟语气在表语从句中，表示间接的命令、要求、请求、建议、决定等，主句中的主语通常是：advice, suggestin, prpsal, request, rder, idea等，从句谓语形式是“shuld＋动词原形”(shuld可以省略，但不可换成wuld)。His request is that they shuld stay here fr the night.他请求他们应该在这儿逗留一晚。My suggestin is that we (shuld) leave the village right nw.我的建议是我们立刻离开这个村子。
