　　一.定義: 在句中的作用相當(dāng)于一個名詞的從句叫做名詞性從句

　　二.分類: 名詞性從句包括四類, 分別是: 主語從句, 賓語從句, 表語從句, 同位語從句

　　三.引導(dǎo)詞: 名詞從句的引導(dǎo)詞包括連詞that / if / whether, 連接代詞who / whom / whose / what / which, 連接副詞when / where / how / why, 另外還有: whatever, whichever, whoever等

　　e. Who made the long distance call to him is not important.

　　f. Whether we’ll go depends on the weather.

　　三.應(yīng)注意的問題:

　　1.以that引導(dǎo)主語從句時, 常用it作形式主語, 而把真正主語后移, 如在以下句型中就是如此: It is + adj / n + that...; It is said / reported / hoped that...

　　3.關(guān)于主句和賓語從句的時態(tài)呼應(yīng):

　　a. He said he would fly to Egypt next day.

　　b. He remembered that he had left her umbrella in the library.

　　a. The teacher told us that light travels faster than sound.

　?、?如果主句是一般現(xiàn)在時或一般將來時, 賓語從句根據(jù)情況選用所需要的時態(tài)
