It is fair to criticize and question the mechanism——that is the culture of research, after all——but it is the prize-givers’ money to do with as they please.(2014年Text3)
A: 该句的难点在于形式主语结构“It is fair to criticize and question the mechanism”;方式状语从句，“as they please”。其他难点结构：“that is the culture of research，after all”为插入语，that代指前面额不定式短语。
B: 该句译文是：合情合理的是批评和质疑这样的机制——毕竟，这是科学研究的文化——但是这是奖项设立者自己的钱，他们可以根据自己的意愿去处理。
