Oh, I’m not feeling well in the stomach. I so much mushroom this morning.

A. shouldn’ t eat

B. musn’t have eaten

C. mustn’t eat

D. shouldn’t have eaten

答案：

A. shouldn’ t eat

B. musn’t have eaten

C. mustn’t eat

(答案→)D. shouldn’t have eaten

解析：考查情态动词用法。根据句意可知是对过去情况进行说明，所以使用情态动词+have done，排除ABC. Should have done本应该做某事实际上却未做。句意：我肚子痛。今天早晨我本不应该吃那么多的蘑菇的。
