You can never imagine difficulty we had the cupboard upstairs.

A. what a; to carry

B. how; to carry

C. what; carrying

D. how; in carrying

答案：

A. what a; to carry

B. how; to carry

(答案→)C. what; carrying

D. how; in carrying

解析：第一空考查感叹句。题中的名词为difficulty，是不可数名词，所以用what 修饰，第二空考查短语：have difficulty( in )doing sth 做什么事情有困难。所以选C。
