Question

19. The team,     to climb the world's second tallest mountain twice, finally decided to give up.

A. having attempted      B. attempting

C. attempted          D. to attempt

Answer 1

19.   A考查非谓语动词。本句中的动词attempt与句子主语the team构成逻辑上的主动关系，而且attempt的动作发生在谓语动词之前，所以使用现在分词的完成式。句意：已经尝试了两次攀登世界上第二髙峰，这支队伍最后决定放弃。故选A。
