名詞性從句指充當名詞成分的從句,下分很多類型,是英語學習的重點,可以說搞懂了名詞性從句,你的英語水平就極大的提升了一個level,而主語從句則是名詞性從句非常重要的一種類別,所以這次小編就為大家?guī)黻P(guān)于主語從句的講解,快點來看看吧!

一. 概念:在句子中擔當主語的從句就叫做主語從句,通常放在主句謂語動詞之前或由形式主語it代替,而本身放在句子末尾。

主語從句使用陳述語序,其通常結(jié)構(gòu)為“引導詞 + 主語 + 謂語 + 其他成分", 但當連接代詞同時充當從句主語時,其結(jié)構(gòu)為“連接代詞 + 謂語 + 其他成分”。

二. 引導詞:

1. that引導

eg. That you are coming to London is the best news I have heard this long time.

2. whether引導

eg. Whether they would come to conference was a question.

3. 連接代詞引導: who,whom, whose, what, which, whoever, whomever, whichever, whatever

eg. Whoever is top from wins the game when two matched players meet.

4. 連接副詞引導: therefore, besides, otherwise, however, moreover, still, thus, meanwhile

eg. How this happended is not clear to anyone.

5. 關(guān)系代詞型what引導

eg. What shoked me was that she never wash her own clothes.

三. 形式主語it:

1. 對關(guān)系代詞型what引導的主語從句,可以使用形式主語。

eg. It is clear enough what he meant.

2. 如果句子是疑問句,則必須用帶形式主語it的結(jié)構(gòu).

eg. Is it true that all of us need to to conference?
