　　52--56 BDACB

　　Section B

　　52.細節判斷題。由第一段開篇的“humorless boss or dour neighbor may not have a personality defect--but a different brain structure”可見本題答案為B項。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.”推斷選項C和D是錯誤的。

　　53.細節題。由第二段中的“We always thought of humor as an intangible part of our personality”可以判斷出正確答案是D項。由第二段最后一句“Now we know humor can be tested and scientifically scrutinized”可以排除選項A。

　　54.細節判斷題。由第三段開頭的“responses of 42 volunteers aged 18 to 70 to written and verbal jokes and cartoons”可判斷正確答案為A項。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”可以斷定選項B和C是錯誤的。

　　55.細節推斷題。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.”可見參與實驗的志愿者是介于18到70歲之間。Shammi分析他們對書面的(written)和口頭的(verbal)笑話和動畫做出的回應。選項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.”可見，半數的志愿者是由于中風、腫瘤或者手術而腦部受損。half和majority并不一致。因此，正確答案為C項。

　　56.邏輯推斷題。原文中的選項A不存在任何幽默，只是現實中最常見的、正常的回應。原文中B選項的回應是幽默的：“既然現在周薪是50美金，一個月后是75美金，那我一個月后再來好了。”而原文中的選項C則是較為粗俗的玩笑。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.”可推斷正確答案是B項，他們會選擇開粗俗的玩笑。
