All possible means __________.However, nothing can __________ Jack from adventuring in that mysterious forest. A．has tried; stop B．has been tried; keep C．have tried; keep D．have been tried; prevent

Answer 1

D

试题分析： 句意：所有可能的手段都已经试过了。然而，没有什么可以阻止杰克在那神秘的森林里的冒险。means当名词解释为“方法”，单复数同型，这里有all，说明这里的means为复数，All possible means 所有可能的手段，方法，是复数，所有的手段方法都试过了，是完成时态。人试方法，方法被试，方法做主语，所以是被动语态，故用have been tired；prevent/stop sb from doing和 keep sb from doing阻止某人做某事，由句意可知选D。 考点: 考查动词的被动语态和动词词组的用法。
