　　52--56 BDACB

　　Section B

　　52.细节判断题。由第一段开篇的“humorless boss or dour neighbor may not have a personality defect--but a different brain structure”可见本题答案为B项。由第三段“People with damage to the right anterior frontal lobe were the least able to appreciate jokes and cartoons...Instead，they showed a preference for silly slapstick humor.”推断选项C和D是错误的。

　　53.细节题。由第二段中的“We always thought of humor as an intangible part of our personality”可以判断出正确答案是D项。由第二段最后一句“Now we know humor can be tested and scientifically scrutinized”可以排除选项A。

　　54.细节判断题。由第三段开头的“responses of 42 volunteers aged 18 to 70 to written and verbal jokes and cartoons”可判断正确答案为A项。由第三段中的“People with damage to the right anterior frontal lobe were the least able to appreciate jokes and cartoons...Instead， they showed a preference for silly slapstick humor”可以断定选项B和C是错误的。

　　55.细节推断题。由第三段第一句“Shammi compared the responses of 42 volunteers aged 18 to 70 to written and verbal jokes and cartoons.”可见参与实验的志愿者是介于18到70岁之间。Shammi分析他们对书面的(written)和口头的(verbal)笑话和动画做出的回应。选项A和B都符合原文，可以排除。由第三段第二句“Half the group had a brain injury caused by stroke;tumor or surgical removal.”可见，半数的志愿者是由于中风、肿瘤或者手术而脑部受损。half和majority并不一致。因此，正确答案为C项。

　　56.逻辑推断题。原文中的选项A不存在任何幽默，只是现实中最常见的、正常的回应。原文中B选项的回应是幽默的：“既然现在周薪是50美金，一个月后是75美金，那我一个月后再来好了。”而原文中的选项C则是较为粗俗的玩笑。由最后一段的“People with damage to the right anterior frontal lobe were the least able to appreciate jokes and cartoons...Instead， they showed a preference for silly slapstick humor.”可推断正确答案是B项，他们会选择开粗俗的玩笑。
