单元语法发散思维

that 引导的同位语从句。一般跟在某些抽象名词 ( 如 belief , fact , hope , idea , news , problem , possibility 等 ) 的后面，用以说明或解释前面的名词。例如：

The idea that computers will recognize human voices surprises many people .

引导同位语从句的词除连词 that 外，还有连接副词 ( how , when , where , why 等 ) 。例如：

I have no idea when Jack will be back .

He can\'t answer the question how he got the money .

同位语从句与定语从句的区别：比较下列两个例句：

We expressed the hope ( that ) they had expressed . ①

We expressed the hope that they would come to visit China again . ②

请看如下分析：

1 . 从语法的角度上看，引导同位语从句的 that 是连词，只起连接的作用，在从句中并不作任何句子成分；而引导定语从句的 that 是关系代词，除了起连接作用外，还在从句中作句子成分 ( 如句①中的 that 在从句中作宾语；句②中 that 只起连接作用 ) 。

2 . 从语义的角度上看，同位语从句与它前面的名词 ( 如 hope ) 是同位关系，表示这个“希望”的内容是“他们再来中国访问”；而定语从句与它前面的名词是所属关系，表示“……的”，起修饰作用。

3 . 同位语从句的连词 that 一般不能省略；而定语从句中的关系代词 that，当其在句中作宾语时，常常可以省略 ( 如句①中的 that 可以省略；句②中的 that 不能省略 ) 。
