What the children in the mountain village need ______ good books.( )
A. is
B. are
C. have
D. has
题目解答
答案
B. are
解析
本题考查主语从句的主谓一致。关键点在于确定主语从句的实际意义,而非表面形式。当what引导的主语从句后接复数名词或不可数名词时,谓语动词需用复数形式或单数形式。本题中,从句的实际意义为复数(good books),因此需用are。
句子结构分析
原句为:What the children in the mountain village need ____ good books.
- What引导主语从句,从句的完整形式为:The children need good books.
- 主语从句的实际意义是复数(good books为复数名词),因此谓语动词需用复数形式。
选项辨析
- A. is:单数形式,与复数主语矛盾。
- B. are:复数形式,符合主语从句的实际意义。
- C. have、D. has:动词形式错误(需系动词,而非实义动词)。
