Our monitor, it clear to us that he didn’t want to waste time playing computer games, left the Internet bar quickly.

A. made

B. having made

C. make

D. Had made

答案：

A. made

(答案→)B. having made

C. make

D. Had made

解析：考查分词做状语。本题中的动词make与句子主语our monitor构成逻辑上的主动关系，故使用现在分词做状语。而且他说这样的话是在他离开网吧之前，是一个在谓语动词之前发生的事情，故使用完成式having done。故B正确。
