A. How

B. How a

C. What

D. What a

答案：

A. How

B. How a

(答案→)C. What

D. What a

解析：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useful advice she gave you !可知选C.
