[解析]
(1)C.细节理解题.根据文章第一段".He asked if we could let him have the food on trust.He promised to repay me the next day"可知他并非忘了带钱,而是没有现金(out of cash),新家里又没有食物,因而想先吃食物之后再付账;故选C.
(2)A.细节理解题.根据文章第二段"I felt stupid and unkind saying this,but I valued my job"可知作者虽然可怜老人但还是拒绝的原因是他很重视他的工作不想失去;故选A.
(3)B.推理判断题.根据文章最后一段"Compassion,on the other hand,is caring in action.I thanked the second man but told him that was not allowed",说明"compassion(同情)"更注重的是"action(行动)",说说容易做起来难;故选B.
