— expensive mobile phone it is!
—Yes, but I think style is quite fashionable,
A. What a; a
B. How; the
C. What an; the
D. How an; the

A. What a; aB. How; the(答案→)C. What an; theD. How an; the解析：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！ 由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！ 注意：当how修饰动词时，动词不跟着感叹词提到主语之前。当后面单词词首音素为元音时，不定冠词用an。下文风格是特指，故选C。
