--- _________ difference the day made! We were very happy. 

A．what

B．how

C．what a

D．how a

答案

C

解析

试题分析：感叹句主要有what和how构成：
1、what修饰名词或名词短语，有以下两种形式： 1. What+a(an)+（形容词）+单数可数名词+主语+谓语！或是：What+名词词组+主语+谓语！ 2. What+(形容词）+可数名词复数或不可数名词+主语+谓语！
2、How引导的感叹句。 how用来修饰形容词、副词或动词。其结构是：How+形容词（副词）+主语+谓语！
根据下文difference the day made，difference本句中是可数名词，故选C。
