同位語表示與之同位的名詞(短語)的實(shí)際內(nèi)容，對前面的名詞(短語)加以補(bǔ)充說明或進(jìn)一步解釋。

例如：

The suggestion that we should develop the natural resources in the region has been discussed.

關(guān)于我們應(yīng)該開發(fā)本地區(qū)資源的建議已經(jīng)討論過了。

同位語從句的連接詞

1.?引導(dǎo)同位語從句的連接詞最常見的是that。

2.?連接詞when, where, why, whether, how 等也可引導(dǎo)同位語從句。

例如：

Have you any idea how fast sound travels? 你知道聲音傳播有多快嗎？

This is some doubt whether he will come. 他是否會(huì)來還不一定呢。

He had no idea why she left. 他完全不明白她為什么會(huì)離開。

3. 同位語從句中常見的先行詞

idea, situation thought, fact, evidence, belief, doubt, fear, hope, question, theory, news, order, 等等。

注意：同位語從句和定語從句的區(qū)別

1. 修飾的詞不同。同位語從句前的先行詞比較有限，且大部分都是抽象名詞；定語從句的先行詞可以是比較復(fù)雜的內(nèi)容，可以即包括人又包括物。

2.?從句的作用不同。同位語從句是用來解釋前面的名詞的，而定語從句則是修飾的作用。

3.?關(guān)系詞的作用不同。同位語從句中that?是連詞，不充當(dāng)任何成分，但是不能省略。而定語從句中that?是充當(dāng)一定成分的，在某些情形下是可以省略的。

翻譯示例：

Many people have stopped buying it, ______________（盡管一再保證這種產(chǎn)品是安全的）.

1. 介詞短語作狀語：所以前半部分作句子的狀語

2. 盡管可以用一個(gè)介詞短語，despite，后面應(yīng)該接名詞短語

3. 同位語從句：assurance后面接一個(gè)同位語從句對“保證”進(jìn)行說明。

答案：despite repeated assurances that the product is safe

1. 同位語從句。that引導(dǎo)從句作orders的同位語，解釋orders的具體內(nèi)容。主句：They received orders. orders內(nèi)容如下：The work be done right away.

2. 同位語從句。that引導(dǎo)從句作news的同位語，解釋news的具體內(nèi)容。主句：The news surprised us greatly. news的內(nèi)容如下：He was kidnapped.

3. that引導(dǎo)從句作information的同位語，解釋information的具體內(nèi)容。主句：Information has been put forward. information的具體內(nèi)容為：More middle school graduates will be admitted into universities.

4. that引導(dǎo)從句作word的同位語，解釋word的具體內(nèi)容。主句：Three days later, word came.

6. 此題為故意考查大家是否能辨別同位語從句與其他從句使用that的區(qū)別而設(shè)置。并不考查同位語從句。第一空為定語從句，why和that都可引導(dǎo)定語從句修飾the reason；第二空為表語從句，根據(jù)句意“……的理由是”只能選擇that，如果because或why就意為“……是因?yàn)椤本湟獠煌?，所以，答案為B。

8. 同位語從句that we’ll never know what a UFO is- not ever作a feeling 的同位語，解釋a feeling 的具體內(nèi)容。that連接同位語從句時(shí)，只起連接作用，不作從句的任何成分。

9. that引導(dǎo)從句作a message的同位語，解釋a message的具體內(nèi)容。a message的具體內(nèi)容為：The meeting won't be held tomorrow.
