GRAMMAR GUIDE同位语从句三要点(一) 概念一般来说，在主从复合句中,用作同位语的从句叫同位语从句。它通常跟在某些名词之后，用以说明或解释该名词表示的具体内容。可以跟同位语从句的名词通 常 有 ： advice, decision, fact, hope, idea, information, message, news, promise, proposal, reply, report, suggestion, word（消息），problem， question, doubt, thought等。例如：They were delighted at the news that their team had won.当听到他们队获胜的消息时，他们欣喜若狂。Where did you get the idea that I could not come？你从哪儿听说我不能来？有时同位语从句可以不紧跟在被说明的名词后面，而被别的词隔开。 如：The thought came to him that Tom might have returned the book.他突然想起汤姆可能已经还了书了。（二）引导词[寻规找矩] 请仔细观察下列句子，注意从句引导词的用法。1. The news that Mr. Li will be our new English teacher is true.2. He hasn’t made the decision whether he will go there. 3. The question who should do the work is being discussed at the meeting.4. I have no idea what the boy is doing in the next room now.5. We haven’t yet settled the question where we are going to spend our summer vacation this year.6.
