Question

You are ______ out all the difficult problems.

1. A.
   enough clever work
2. B.
   enough clever to work
3. C.
   clever enough to work
4. D.
   clever enough work

Answer 1

C
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。
