问题补充：

—Has anyone taught him how to do it?

—Sure. Lots of advice, but he hasn’t made a decision.

A. gave

B. was given

C. have been given

D. has been given

答案：

A. gave

B. was given

C. have been given

(答案→)D. has been given

解析：考查主谓一致时态和语态：句意：--有人教他怎么做吗？--当然，别人给了很多建议，但是他还没有做决定。主语是Lots of advice不可数名词，谓语是单数，排除C，从后面的but he hasn’t made a decision.可知用现在完成时，建议是被给的，选D。
