表语从句
1.表语从句
① 位置
★ 在纯系动词之后；
★ 在半系动词之后的从句既可以看作表语从句，也可以看作宾语从句.
② 连词
★ 陈述句充当表语从句，连词为that(that没有实际含义，在从句中只起连接作用，不作任何语法有成分)，从句为"that + 陈述句"，that不能省略；
★ 一般疑问句充当表语从句，连词为whether(whether表示"是否"的含义，在从句中只起连接作用，不作任何语法成分)，从句为"whether + 陈述句语序"，whether不能省略；
★ 特殊疑问句充当表语从句，连词为特殊疑问词(特殊疑问词都有自己的含义，在从句中作一定的语法成分)，从句为"特殊疑问词+陈述句语序"，特殊疑问词不能省略.
③ 例子
eg1: My idea is that we should go home early.
eg2: The problem is whether they are willing to help us.
eg3: That's why we had to put off the meeting.
注：除了上述三种连词外还可以用 as if = as thougth、because连接表语从句，主要是从它们引导的从句所处的
位置进行判断.eg4: it looks/seems as if you have got no experience.
eg5: That he didn't turn up is because he had to accompany his mother.
分析：
That he din't turn up : that引导的主语从句
is：主句的系动词
because he had to accompany his mother: because 连接的表语从句
