You are out all the difficult problems .
A. enough clever work
B. enough clever to work
C. clever enough to work
D. clever enough work

A. enough clever workB. enough clever to work(答案→)C. clever enough to workD. clever enough work解析：考查enough的用法。enough修饰形容词必须放在形容词后，修饰名词时放在名词的前面或后面都行，一般是放名词前；故排除A、B；固定句型：形容词+enough +to do sth.“足够......可以做某事。”句意“你足够聪明，可以算出所有的难题。”故选C。

就是这个解释
