3．同位语从句在句子中的位置

同位语从句有时可以不紧跟在它所说明的名词后面，而是被别的词隔开。

He got the news from Mary that the sports meeting was put off.

他从玛莉那儿得到消息：运动会推迟举行。

4．同位语从句的虚拟语气

名词suggestion，order，demand，command，request，desire，proposal等后的同位语从句要使用虚拟语气，即从句的谓语动词用"should＋do"，should可省略。

(1)Do you know his suggestion that we (should) start our work right now?

你知道他建议我们立即开始工作吗？

注意：同位语从句与定语从句的区别：

(1)定语从句中的that既代替先行词，同时也在从句中作某个成分(主语或宾语)；而同位语从句中的that是连接词，只起连接主句与从句的作用，不充当任何成分。

(2)定语从句是形容词性的，其功能是修饰先行词，对先行词加以限定，描述先行词的性质或特征；同位语从句是名词性的，其功能是对名词进行补充说明。

(2)The news that he told me is that Tom would go abroad next year.

他告诉我的消息是汤姆明年将要出国。(第一个that引导的是定语从句，that在从句中作宾语)

(3)The news that Tom would go abroad was told by him.汤姆将要出国的消息是他说的。(that引导同位语从句，that在句中不作任何成分)
