(1) 同位语从句的引导词引导同位语从句的连词有that，whether (不能用if) 或连接副词how，when，where等，这些连词一般不能省略。例如：The fact that you havent enough time to do the work is simply unbelievable.你没有足够的时间去做这件工作，这简直令人

9、 go abroad next year. （定语从句，that在从句中作told的宾语，that可省略。）他告诉我的消息是汤姆明年将出国。The order that we should send a few people to help the other groups was received yesterday.

(同位语从句)人们经常讨论大多数劳动力将会在家里工作的可能性Our team has won the game, which made us very happy. (定语从句

12、)我们的队赢了，这让我们很高兴。(3) 从性质上区别同位语从句是名词性的，其功能是对前面的抽象名词进行补充说明，而且可以用此抽象名词作主语，把同位语从句改为表语从句；定语从句是形容词性的，其功能是对其先行词的修饰或限制，不宜改为此类表语从句。例如： Then the question arose where we were to get the machine needed.（同位语从句） The question was where we were to get the machine needed. 然后就产生这样一个问题，我们上哪儿去找所需要的机器。Could you tell me t
