我们看题：

Campus-wide discussion on academic integrity can be (i)_____ by the fact that faculty and students tend to define cheating in (ii)_____ ways. Even when they concur on what cheating means, faculty and students often assign different levels of severity to specific violations. These differences can serve as a major (iii)_____ the creation of a commonly accepted set of standards of integrity that are consistently applied to all academic work within the campus community. 

那么，第（ii）空怎么选？还记得我们上一讲中讲到的么？“GRE填词中，即使没有空白的句子也是需要需要需要看的。因为这些没有空白的句子往往提供了重要的信息，是整个题目的语境的重要组成部分，对于需要填空的句子提供了必要的提示，为我们选词提供了重要的甚至是关键的依据。”

于是，我们迅速看到 “Even when they concur on what cheating means, faculty and students often assign different levels of severity to specific violations.”这一句给我们的提示：“就算在what cheating means上意见一致，faculty和students还是经常有不同”。可见第（ii）空的答案应该是D.disparate。

然后，我们可以赶紧回去做第（i）空了吧？不着急，我们其实应该接着往下看：第三句，也就是第（iii）空所在的那个句子，主要的逻辑是：“these differences”与“the creation of a commonly accepted set of standards of integrity” 之间的关系，简化说来就是“区别”与“共同”之间的关系。

并且，依托上一句那个没有空白的那个句子“Even when they concur on what cheating means, faculty and students often assign different levels of severity to specific violations.”——当然，在此我们再次强调没有空白的句子在整个题目中的重要作用——我们迅速可以从第三栏中选第（iii）空的答案：H. impediment（阻碍）to。
