I woke up with bad headache, yet by evening the pain had gone.

A. the; the

B. the ; an

C. a; the;

D. a; an

答案：

A. the; the

B. the ; an

(答案→)C. a; the;

D. a; an

解析：headache是由名词head和动词ache组成的合成词,意为“头痛”,可用作不可数名词,也可用作可数名词。

headache引申可表示“令人头痛的事”,可用于表达感情上的痛苦和不快,用作可数名词,并且常接for。

evening应该指的是当天的早晨，故前面用定冠词修饰。have a headache 头疼，故选C。
