　　同位语从句

　　同位语从句用于对前面的名词作进一步解释，说明名词的具体内容。同位语从句一般由that引导，但也可以由whether以及连接代词和连接副词引导。

　　A 同位语从句一般跟在名词的后面

　　同位语从句一般跟在名词fact, hope, idea, news, doubt, suggestion, information, opinion, decision, discovery, truth, promise, statement28, problem, rule等后面。

　　到哪儿去度暑假，这个问题我们还没有决定。

　　There is no doubt that we will win.

　　毫无疑问我们会赢的。

　　当含有同位语从句的主句谓语部分过短时，可以把谓语动词提前，使同位语从句与名词隔开，以避免头重脚轻的现象。

　　Word came that Mr President would come and inspect30 our school himself.

　　有消息说总统先生将亲自来视察我们学校。

　　B 使用虚拟语气的同位语从句

　　在一些表示“建议、命令、要求”的名词后的同位语从句中，谓语动词用"should + 动词原形"，should可省略。

　　This is our only request that this (should) be settled as soon as possible.

　　尽快解决这个问题，这是我们惟一的请求。
