______ excited the mother was when she heard her son’s voice from the space station!

A. How B. What C. What a D. What an

【答案】

A

【解析】

句意：当她听到来自空间站的儿子的声音时，母亲多么兴奋啊！考查感叹句。英语中感叹句有两种形式：1.what引导的感叹句，其构成：what+a/an+形容词+可数名词单数+主语+谓语!/ what +形容词+可数名词复数+主语+谓语!/ what +形容词+不可数名词复数+主语+谓语! 2. How引导的感叹句，其构成：how+形容词/副词+主语+谓语!本句中excited激动的/兴奋的，是形容词；the mother was…是主语+系词…（相当于主谓结构）；根据句意语境，可知其感叹句需用“how+副词+主谓句”结构，故选A。
