问题补充：

He in America for 3 years when he was young, so he can speak fluent English.

A. has lived

B. had lived

C. was living

D. lived

答案：

A. has lived

B. had lived

C. was living

(答案→)D. lived

解析：考查动词时态。句意：他年轻时在美国住了三年，因此他能说流利的英语。一般过去时表示过去的一段时间内或过去某个时间点发生的动作或状态。此处的live发生在他住在美国的时间里，所以应用过去时。故D正确。
