高中英語表語從句講解及習題

  一、定義:

1.表語從句就是用一個句子作爲表語。說明主語是什麼或者怎麼樣,由名詞、形容詞或相當於名詞或形容詞的詞或短語充當,和連繫動詞一起構成謂語。

Eg:The problem is puzzling. 這問題令人困惑

主語 連繫動詞 形容詞作表語

The problem is when we can get a pay rise. 問題是什麼時候我們可以得到加薪.

主語 連繫動詞 一個句子作表語---表語從句

2.連接表語從句的連接詞有:that, what, who, when, where, which, why, whether,how.

He has become a teacher. 他已經成爲一名教師。

He has become what he wanted to be ten years ago.

他已經成爲了他10年前想成爲的。

She has remained there for an hour.

她曾在那裏停留了一個小時。

She has remained where I stood yesterday for an hour.

她一直在我昨天站的地方站了一個小時。

His suggestion is good. 他的建議是好的。

His suggestion is that we should stay calm.

他的建議是,我們應該保持冷靜

The question is when he can arrive at the hotel.

問題是,他什麼時候可以到達酒店。

who will travel with me to Beijing tomorrow.

誰與我明天將前往北京。

why he cried yesterday. 昨天他爲什麼哭。

how I can persuade her to join us in the party.

我怎麼能說服她加入我們的派對。

whether the enemy is marching towards us.

是否敵人正向我們行進.

  二、注意:

1.表語從句一定要用陳述語序。

False: The question is when can he arrive at the hotel.

Right: The question is when he can arrive at the hotel.

2.不可以用if,而用whether 連接表語從句(as if 例外)。

引導賓語從句時可以互換if/whether 位於介詞後要用whether,位於句首時要用whether 引導表語從句,主語從句,同位語從句時要用whether

False: The question is if the enemy is marching towards us.

Right: The question is whether the enemy is marching towards us.

Right: It looked as if he had understood this question.

3.不像賓語從句,在有表語從句的複合句中,主句時態和從句時態可以不一致。

Right: The question is who will travel with me to Beijing tomorrow.

Right: The question is why he cried yesterday.

在表語從句中不可以省掉。

表語從句的.基本用法:

表語從句只能置於主句之後,而主句的動詞只能是聯繫動詞。

名詞性從句在be等系動詞後作表語時被稱爲表語從句.

例如: The problem is how we can get the things we need. (how 在表語從句中充當方式狀語)

問題是我們怎樣能弄到我們需要的東西。

The scissors are not what I need. (what 在表語從句中充當賓語)

這把剪刀不是我所需要的。

What I told him was that I would find him a good play.

我告訴他的是我會給他找個好劇本。(what在主語從句中作直接賓語, that作爲表語從句的引導詞在該表語從句中不充當句子成分, 不能省略)

That is what I want to tell you. (what在表語從句中充當直接賓語)

那就是我想要對你講的。

That is why she failed to pass the exam. (why 在表語從句中充當原因狀語)

那就是她考試不及格的原因。

注意: “That is why...”是常用句型, 意爲“這就是……的原因/因此……”, 其中why引導的名詞性從句在句中作表語, 該句型通常用於針對前面已經說明過的原因進行總結,又如: That is why you see this old woman before you know, Jeanne. (前文提到Jeanne對老婦人顯得蒼老憔悴深感詫異, 說話人對她講述了其中的原因之後,用這一句來進行概括)。

That is why I came. 這就是我來的原因。
