He must have done it well because he told me he just did what he to do. A. has been told

问题补充：

He must have done it well, because he told me he just did what he to do.

A. has been told

B. had been told

C. was told

D. had told

答案：

A. has been told

(答案→)B. had been told

C. was told

D. had told

解析：考查时态和语态。句意：他一定会做得很好，因为他告诉我他是按照被告知地那样去做的。根据句意说明他被告知应该使用被动语态的形式，而且他被告知是在他做事情之前，应该使用过去完成时的被动语态。故B正确。
