同位語:
在復(fù)合句中充當(dāng)同位語的名詞性從句稱為同位語從句。一個(gè)名詞(或其它形式)對(duì)另一個(gè)名詞或代詞進(jìn)行補(bǔ)充說明,這個(gè)名詞(或其它形式)就是同位語。
1.用法
同位語從句一般跟在某些名詞后面,用以說明該名詞表示的具體內(nèi)容。
I heard the news that our team had won.我聽到了我們隊(duì)獲勝的消息。
①可以跟同位語從句的抽象名詞通常有news,idea,fact,promise,question,doubt,thought,hope,message,suggestion,word(消息),possibility等。
I’ve come from Mr. Wang with a message that he won’t be able to see you this afternoon.
我從王先生那里來,他讓我告訴你他今天下午不能來看你了。
②在某些名詞表“建議,命令,要求等”(如demand, wish, suggestion, resolution等)后面的同位語從句要用虛擬語氣 (即should+動(dòng)詞原形;should可省)。
There was a suggestion that Brown should be dropped from the team.
有一項(xiàng)建議是布朗應(yīng)該離隊(duì)。
③同位語從句前名詞的數(shù):同位語從句前的名詞通常用單數(shù)形式,并且往往帶有限定詞(word除外)加以修飾。
Where did you get the idea that I could not come?你在哪兒聽說我不能來?
2.連詞
英語中引導(dǎo)同位語從句的詞通有that,whether,連接代詞what,who,連接副詞how, when, where等。(注:if, which 不能引導(dǎo)同位語從句。)
(1)連詞that引導(dǎo)同位語從句(注:引導(dǎo)同位語從句的that不能省略)
The idea that you can do this work well without thinking is quite wrong.
你認(rèn)為不動(dòng)腦筋就能做好這件工作的想法是完全錯(cuò)誤的。(作idea的同位語)
【注】引導(dǎo)同位語從句的連詞that通常不省略。
(2)連詞whether引導(dǎo)同位語從句(注:if不能引導(dǎo)同位語從句)

3.分隔式同位語從句
有時(shí)同位語從句可以不緊跟在說明的名詞后面,而被別的詞隔開。在語法上叫做分隔式同位語從句。

4.定語從句與同位語從句
同位語從句是用于說明所修飾名詞的具體內(nèi)容的,它與被修飾詞語通??梢詣澋忍?hào);而定語從句是限制所修飾名詞的,它的作用是將所修飾的名詞與其他類似的東西區(qū)別開來。
同位語從句中的引導(dǎo)詞that不做成分,而定語從句中的引導(dǎo)詞that做成分。
定語從句中,關(guān)系代詞做賓語可以省略;同位語從句的引導(dǎo)詞不可以省略。
We are glad at the news that he will come. 聽到他要來這個(gè)消息我們很高興。
We are glad at the news that he told us. 聽到他告訴我們的這個(gè)消息我們很高興。
