(答案→)B. Had, would not have been claimed
C. Should, would not be cost
D. Had, would not have been cost
解析：考查虚拟语气和动词：句意：如果当地政府把更多的注意力放在孩子的安全上，甘肃省的20多个孩子的生命就不会被夺取了。这是和过去相反的虚拟语气，if条件句应该用过去完成时，也可以省略if把had提前，主句用would have done，答案在BD里面选择，claim是“夺去”，claim one’s life夺取某人的生命，cost是“使…丧失”，用cost sb one’s life，所以选B。
