I have no idea when he will come back. 二、英语中引导同位语从句的词通有连词that，whether；连接代词who,whom,which,what 等；连接副词how, when, where，why等。（注：that 在从句中不作句子成分，只起连接作用；if 不能引导同位语从句。） 例如：1.I heard the news that our team had won.我听到了我们对获胜的消息。2. I had no idea that you were here. 我不知道你在这里。3.He must answer the question whether he agrees to it or not. 他必须回答他是否同意这样一个问题。4. I have no idea what size shoes she wears.我不知道她穿几号的鞋。（what作定语） 5.I have no idea which wine is bestits a matter of personal taste.我不知道哪种酒最好，这是个人口味的问题。（which作定语） 6.The question who will take his place is still not clear. （who作主语）7.We havent yet settled the question where we are going to spend our summer vacation.到哪儿去度暑假，这个问题我们还没有决定。(where 作地点状语)三、有时同位语从句可以不紧跟在说明的名词后面，而被别的词隔开。 1.The thought came to him that maybe the enemy had fled the city 他突然想起可能敌人已经逃出城。2.Several years later, word came that Napoleon himself was coming to inspect them. 几年以后，有消息传来说拿破仑要亲自检阅他们。四、有时可用 namely (即), that is to say (也就是说), in other words (换句话说), that is (那就是), for example 等引出同位语, 说明其前面的名词或代词。有时同位语直接跟在名词或代词的后面。1. He told us the good news, namely, the museum is open to all.2. There is only one way of improving your English , that is , to practice more.3.Altogether Dolly had lived for six years, half the length of the life of the original sheep.五、同位语从句-特殊形式：当名词为suggestion, request和order等名词后的同位语从句用虚拟语气。例如：1） She made a reque
