从句一直深受高考的青睐,一直是很多同学做完型和阅读题型的老大难问题,虽然考的多,但总有同学被它弄得晕头转向。今天给大家分享的是同位语从句,一起来学习一下吧~
在复合句中充当同位语的名词性从句称为同位语从句。一个名词(或其它形式)对另一个名词或代词进行补充说明,这个名词(或其它形式)就是同位语。
1.用法
同位语从句一般跟在某些名词后面,用以说明该名词表示的具体内容。

①可以跟同位语从句的抽象名词通常有news,idea,fact,promise,question,doubt,thought,hope,message,suggestion,word(消息),possibility等。
I’ve come from Mr. Wang with a message that he won’t be able to see you this afternoon.
我从王先生那里来,他让我告诉你他今天下午不能来看你了。
②在某些名词表“建议,命令,要求等”(如demand, wish, suggestion, resolution等)后面的同位语从句要用虚拟语气 (即should+动词原形;should可省)。
There was a suggestion that Brown should be dropped from the team.
有一项建议是布朗应该离队。
③同位语从句前名词的数:同位语从句前的名词通常用单数形式,并且往往带有限定词(word除外)加以修饰。
Where did you get the idea that I could not come?你在哪儿听说我不能来?
