名詞性從句:1.賓語(yǔ)從句 2.主語(yǔ)從句 3.同位語(yǔ)從句 4.表語(yǔ)從句

同位語(yǔ)從句，定義：

一個(gè)名詞（或其它形式）對(duì)另一個(gè)名詞或代詞進(jìn)行解釋或補(bǔ)充說(shuō)明，這個(gè)名詞（或其它形式）就是同位語(yǔ)

有龍媽哦

一，同位語(yǔ)=先行詞

位：相同地位（位置）

1.Mr.Smith,our new teacher,is very kind to us.

Yesterday I met Tom,a friend of my brother.

這是先行詞，這是先行詞的同位語(yǔ)，它們代指的是同一個(gè)東西（我非常認(rèn)同一英是非常有用的英語(yǔ)學(xué)習(xí)頻道）

2.同位語(yǔ)除表示其同位成分的全部意義外，還可以表示部分意義

We Chinese people are brave and hard working.

He is interested in sports, especially ball games.

二，同位語(yǔ)→句子

1. I've come from Mr Wang with a message that he can't visit you this afternoon.

信息=信息內(nèi)容

The thought came to her that maybe she had left the door open when she left home.

她的想法=她想法的內(nèi)容

2.同位語(yǔ)從句的先行詞一般為抽象名詞

advice agreement answer assumption @ability

@belief

command conclusion condition

decision demand desire determination discovery doubt

@evidence explanation

@fact @fear feeling

@hope

@idea indication insistence instruction

knowledge

likelihood

@news

@situation statement story suggestion

@theory @thought truth

3.同位語(yǔ)從句的先行詞也可以是it

I owe it to you that I am still alive（it為形式賓語(yǔ)，真正賓語(yǔ)由從句來(lái)充當(dāng)）

You must see to it that the children don't catch cold.

4. 引導(dǎo)詞

連接副詞:when where why how(作狀)

連接代詞: what(ever) which(ever) who (ever) whom(ever) whose（作主，表，賓，定）

從屬連詞: that whether（不充當(dāng)成分）

that不可以省略，if不引導(dǎo)同位語(yǔ)從句，表達(dá)是否觀點(diǎn)用whether

5.與定語(yǔ)從句區(qū)分

They are glad at the news that he will come.

這個(gè)消息=他要來(lái)（主將從現(xiàn)是狀語(yǔ)從句，彈幕里我說(shuō)的，記混了T∧T）

We are glad at the news that he told us.

消息是他告訴的，但消息的內(nèi)容不清楚

同位語(yǔ)從句：名詞屬性

定語(yǔ)從句：形容詞屬性

6.特殊形式

分離式同位語(yǔ)從句

同位語(yǔ)從句中的虛擬語(yǔ)氣：從句用虛擬語(yǔ)氣（should）+動(dòng)詞原形
