单选题 It is fashionable A rationalizing our collaboration in all this by arguing that, well, men like to fight and injure their fellows, and B such games as football should be encouraged to discharge C this original-sin urge into less harmful channels D than , say, war.

【正确答案】 A

【答案解析】解析：rationalizing一to rationalize。句意：用以下主张来解释我们这种合作是比较流行的：人类喜欢相互打斗并伤害同类，那么就应多鼓励足球这样的比赛，因为用这种渠道来释放原罪般的冲动所带来的伤害要小于战争。句首的it是形式主语，真正的主语是fashionable后面的部分。这种情况下，常用不定式结构引导真正的主语，而动名词结构常用于good，useless，worthwhile等特殊形容词之后。故rationalizing改为to rationalize。
