語法小知識:主語從句概念解析
名詞性從句指充當(dāng)名詞成分的從句,下分很多類型,是英語學(xué)習(xí)的重點(diǎn),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(diǎn)來看看吧!
一. 概念:在句子中擔(dān)當(dāng)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(dǎo)詞 + 主語 + 謂語 + 其他成分", 但當(dāng)連接代詞同時充當(dāng)從句主語時,其結(jié)構(gòu)為“連接代詞 + 謂語 + 其他成分”。
二. 引導(dǎo)詞:
1. that引導(dǎo)
eg. That you are coming to London is the best news I have heard this long time.
2. whether引導(dǎo)
eg. Whether they would come to conference was a question.
3. 連接代詞引導(dǎo): 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(dǎo): 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(dǎo)
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(dǎo)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?
