【解析】
【详解】
考查虚拟语气。句意：如果没有青霉素，很多人在二战中就会死于疾病或小的伤口。if条件句用had done表示和过去的事实相反，主句用would have done表示虚拟。故选B。
【点睛】
虚拟语气在条件句中的用法是：虚拟条件句与现在事实相反的假设，从句是If+主语+动词的过去式（动词be用were)，主句是：主语+should,would, might,could＋动词原形；与过去相反的假设从句用：If+主语+had +过去分词，主句是：主语＋should, would, might, could＋have done；与将来相反的假设，从句用1、If+主语+动词过去式，主语＋should, would do，2、If+主语+were to+动词原形，加主句3、If+主语+should +动词原形，加上主句的might, could＋动词原形。
I think it’s time they were taught a lesson.我想现在该给他们一点教训了。
注：time前有时有about和high修饰：
I think it’s high time that she made up her mind.我想她该拿定主意了。

A．visitedB．had visited
C．would visitD．would have visited
