7．Most dog owners believe their dogs experience guilt，but animal behaviorists say the"guilty look"of a dog is simply a reaction toyou and that dogs lack the ability to feel shame．
Alexandra Horowitz，a psychology professor and principal investigator at the Horowitz Dog Cognition Lab at Columbia University once carried out a study on dog"guilt"．She videotaped 14dogs in a series of trials and observed how they reacted when their owners left the room after instructing them not to eat a treat．When the owner was gone，Horowitz gave some of the dogs the forbidden treat．Then she would tell the owners whether their dogs had eaten the treat or had behaved．However，Horowitz wasn't always honest with them．
Horowitz found that the dogs'"guilty looks"had little to do with whether they'd eaten the treat or not．In fact，dogs that hadn't eaten it but were scolded by misinformed owners tended to exhibit the most elements of the"guiltylook"．
Horowitz says this shows that the dogs'body language is actually a response to their owner's behavior---not an experience of shame for a misdeed．Why then，do dogs look so ashamed when we scold them？
Maybe tat look of guilt is the result of a learned association．When you scold your dog for chewing up a pair of slippers，he quickly learns that if he lowers his head and tucks his tail，the undesirable response---raised voice and angry expression---is more likely to disappear．

解答 24．B 细节理解题．but animal behaviorists say the"guilty look"of a dog is simply a reaction toyou 但动物行为学家说"心虚"的狗是对你的反应，所以B选项符合题意．
25．C 推理判断题．根据文章第二段，She videotaped 14dogs in a series of trials and observed how they reacted Alexandra Horowitz她拍摄了14只狗进行了一系列的试验，并观察他们的反应时，可以推断出她是通过实验的方式来完成自己的研究的，故答案选C．
26．B 推理判断题．根据文章第一段的句子but animal behaviorists say the"guilty look"of a dog is simply a reaction toyou and that dogs lack the ability to feel shame．但动物行为学家说"心虚"的狗是对你的反应，狗缺乏感到羞耻的能力．所以答案选B．
