同位語從句的引導詞
引導同位語從句的詞語通常有連詞that，whether，連線代詞和連線副詞等。
1. 由that引導

【注意1】在某些名詞如demand, wish, suggestion, resolution等後面的同位語從句要用虛擬語氣。如：

【注意】whether 可引導同位語從句，但if不能引導同位語從句。
3. 由連線代詞引導

關於分離同位語從句
有時同位語從句可以和同位的名詞分開。如：

同位語從句與定語從句的區別
1.意義的不同
同位語從句是用於說明所修飾名詞的具體內容的，它與被修飾詞語通常可以劃等號;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別開來：
We are glad at the news that he will come. 聽到他要來這個訊息我們很高興。news的內容就是that he will come，故that引導的是同位語從句
We are glad at the news that he told us. 聽到他告訴我們的這個訊息我們很高興。that從句是限制the news的內容的，即我們高興只是因為他告訴的這個news而不是其他的news，故that從句為定語從句
2. 引導詞的不同
what, how, if, whatever 等可引導名詞性從句，但不引導定語從句。
3. 引導詞的功能上的不同
that引導同位語從句時，它不充當句子成分，而引導定語從句時，它作為關係代詞，要麼充當定語從句的主語，要麼充當定語從句的賓語。如上例 that he told us中的that就充當told的賓語。
4. 被修飾詞語的區別
同位語從句所修飾的名詞比較有限，通常有hope, wish, idea, news, fact, promise, opinion, suggestion, truth等，而定語從句所修飾的名詞則非常廣泛。 另外，when和where 引導定語從句時，通常只修飾表示時間和地點的名詞，而它們引導同位語從句時卻不一定;又如why引導定語從句，它通常只修飾名詞the reason，而它引導同位語從句時則不一定：
I have no idea when they will come . 我不知道他們什麼時候來。同位語從句
I’ll never forget the days when I lived there.. 我永遠不會忘記我住在那兒的日子。定語從句
We don’t understand the problem why this is the best choice. 我們不明白這個問題，為什麼這是最好的選擇。同位語從句
