题目

she wants to know( )her uncle likes the new shirt A that B which C if D what（解析
do you know ( )?A What is the population B how many population of dalian is Chow much population is in dalian D what the population of dalian is （解析

答案

题目上的选C.if
她想知道她叔叔是不是喜欢这件新衬衫.
由于从句中成分齐全,不缺成分,所以which,what都排除.根据句意选if.
下边的选D,population作人口讲,没有单个数量的概念,对人口提问有两种：
what's the population of China?
how many people are there in China?
再者,这是一个一般疑问句,一般疑问句构成就是：一般疑问词+陈述句语序,所以答案选D.
