3. 表语从句

　　表语从句对主语的内容起解释和阐述的作用;若表语从句用 that 引起， that 起连接作用，不能省略。表语从句也可用连接词 how, when, where, why, what 引起。由 because 引起的表语从句通常只用在 “this/that/it is because…” 结构中。 与此形成对比的是：The reason (why) …is that…

　　4. 同位语从句的常用的引导词that在从句中不做成份，但不能省略。有时也可由 whether, how, why, where, when 等来引导。例如：

　　We have got the news that our team won the football match.

　　Word came that he was needed at home. The question whether or not I should help him in such a case troubled me greatly.

　　注意区分定语从句和同位语从句。

　　The idea that girls are not as clever as boys is harmful.(同位语从句)

　　The idea that struck him startled his parents.(定语从句)

　　在名词性从句中 “疑问词ever”不能换成”no matter+疑问词”,视情况可以换成 “anyone /anybody who”或”anything that”, 在状语从句中可以换用.
