概述
一.定義: 在句中的作用相當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.引導詞: 名詞從句的引導詞包括連詞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
主語從句
一.定義: 在句中充當主語的從句就是主語從句
二.示例:
a. That he looked at me in that strange way puzzled me.
b. Whether we can control the floods is still uncertain.
c. What he wanted to see was an end to all the armies of the world.
d. When the broadcast station will be ready is unknown.
e. Who made the long distance call to him is not important.
f. Whether we’ll go depends on the weather.
三.應注意的問題:
1.以that引導主語從句時, 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...
a. It is certain that fuels like coal and oil cause a lot of pollution.
b. It was said that only three people in the world could understand it at that time.
2.whether引導主語從句時, 常置于句首 (此時whether不能用if代替),
也有后移的用法 (此時whether可以用if代替)
a. Whether they will come is not yet known.
b. It is not yet known whether they will go there.
