What ______ great fun we had ______ the changes _____ the birds’ numbers!

A. a; recorded; in

B. a; to record; of

C. /; recording; in

D. /; record; of

【答案】

C

【解析】

句意：在记录鸟类数量的变化活动中我们多么开心啊！考查感叹句、动词固定搭配以及介词用法。根据What ______ great fun we had ______ the changes _____ the birds’ numbers!可以推断句意为在记录鸟类数量的变化活动中我们多么开心啊！句子have fun doing为固定词组“做某事很高兴”，其中fun为不可数名词，故感叹句使用What+形容词+不可数名词！的形式，而“在…方面”用介词in；故答案选C。
