the question whether he should do this troubled him. 是否該做這件事這一問題使他很煩惱。
注意：由連接詞that （一般不可省略） 引導的同位語從句，在句子結構上與關系代詞that引導的定語從句有相似之處，但有區別：
1) the news that he ha d landed on the moon spread all over the country. 他登上月球的消息傳遍全國。
2）the news that john told us interested all of us.他告訴我們的消息使大家都感趣。
解析：1）句中that從句中本身的內容就是“news ”內容本身，that在句子中不充當任何成分，起連接作用，所以，本句中的that從句 是同位語從句；而2）句中that從句說明“ news ”是怎樣獲得的，不涉及“news”的內容， that從句中充當 “tell”的賓語，所以，本句中的that從句 是定語從句。另外，可帶同位語從句的名詞主要是少數一些可加入具體內容的表示信息、思想等概念的名詞，如：fact，news，idea，truth，belief，doubt，hope，possibility，order，wish，message，promise，suggestion，report，reply，problem, question, thought等。
2. 連接副詞how，when，where等引導的同位語從句。
you have no idea how worried i was！你不知道我是多么著急。
