3. 表語從句

　　表語從句對(duì)主語的內(nèi)容起解釋和闡述的作用;若表語從句用 that 引起， that 起連接作用，不能省略。表語從句也可用連接詞 how, when, where, why, what 引起。由 because 引起的表語從句通常只用在 “this/that/it is because…” 結(jié)構(gòu)中。 與此形成對(duì)比的是：The reason (why) …is that…

　　4. 同位語從句的常用的引導(dǎo)詞that在從句中不做成份，但不能省略。有時(shí)也可由 whether, how, why, where, when 等來引導(dǎo)。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.

　　注意區(qū)分定語從句和同位語從句。

　　The idea that girls are not as clever as boys is harmful.(同位語從句)

　　The idea that struck him startled his parents.(定語從句)

　　在名詞性從句中 “疑問詞ever”不能換成”no matter+疑問詞”,視情況可以換成 “anyone /anybody who”或”anything that”, 在狀語從句中可以換用.
