The visitors lost their way in the forest ;           made things worse. was that it began to rain.

A.that

B.which

C.who

D.what

答案

答案:D

题目分析:what引导主语从句,作主语从句的主语;that引导主语从句,不做成分,本题中was前面是主语从句,后面是that引导的表语从句。句意:旅行者们在森林中迷路了,更糟糕的是天气还开始下雨了。

点评:名词性从句分为主语、宾语、表语、同位语从句四种,同位语从句和定语从句的区别在于:that作为关系代词,可以引导定语从句,充当句子成分,在从句中作宾语时可以省略; that引导同位语从句时,起连词的作用,没有实际意义,不充当句子成分,一般不能省略。

试比较下面两个例句:

I had no idea that you were here.(that引导同位语从句,不能省略)

Have you got the idea(that)this book gives you of life in ancient Greece?(that引导定语从句,作宾语,可以省略)
