I haven't settled the problem of        I'll go back home during the coming May Day.

A which                B. what            C. whether             D. where

答案

答案:C

题目分析:A which哪一个 B. what什么            C. whether是否             D. where在哪里;句意:我还没有决定是否在即将到来的五一我会回家。whether引导同位语从句,故选C

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)
