一、选择题1．____________exciting the football game was!A．How B．How an C．What D．What an A解析：A【解析】【详解】句意：这场足球赛多么激动人心！考查感叹句。
英语感叹句由what和how引导，what后面跟名词，how后面跟形容词或副词。
exciting令人兴奋的，是形容词，故此句结构：How +形容词 +主语 +谓语！故选A。
【点睛】判断感叹句是由what还是how引导的方法：首先，断句。
从句子后面向前看，找到“主语＋谓语＋其他”部分，把句子断开；其次，观察。
观察句子前面剩余部分为名词（词组），还是形容词或副词；若是名词（词组），那么本句是由what引导；若是形容词或副词，那么本句就由how 引导。

分析题干“_________energetic girl she is”，去掉主谓she is，还剩下energetic girl，结构为形容词+名词，即形容词修饰名词，中心词为名词，排除A项。
再由girl为可数名词单数，故选C。
【点睛】本题考查感叹句式，常用的感叹句式为两种，一个是what引导，一个是how引导。
What+a/an+adj+可数名词单数+主+谓；what+adj+可数名词复数/不可数名词+主+谓。
How+adj/adv+主+谓。
