问题补充：

He as a national hero for winning the first gold medal for his country in the Olympics.

A. regarded

B. was regarded

C. has regarded

D. had been regarded

答案：

A. regarded

(答案→)B. was regarded

C. has regarded

D. had been regarded

解析：考查时态和语态。固定搭配:regard sb as…认为某人是…；本句是这个结构的被动语态的形式。本题的AC项没有使用被动语态的形式。D项的时态是过去完成时，从上下文中看不出有过去的过去的意思。句意：因为在奥运会上为国家赢得了第一枚金牌，他被认为是国家英雄。故B正确。
