问题补充：

—I am really struck by your spoken English. You speak so fluently. Have you been abroad.

—Yes, I in London for two years．

A. have stayed

B. stayed

C. had stayed

D. have been staying

答案：

A. have stayed

(答案→)B. stayed

C. had stayed

D. have been staying

解析：考查时态。考生看到for two years，容易误选A。但句子中并没有说什么时候回来的，所以不能选用完成时。句意：“我在伦敦呆了两年。”根据语境说明stay的动作发生在过去，所以用过去时，延续性动词的过去时可以与时间段连用，因此选择B。
