6.Scientists have discovered a real-life"moral compass"in the brain that controls how we judge other people's behavior.The region,which lies just behind the right ear,becomes more active when we think about other people's misdemeanor or good works.In an experiment,researchers were able to use powerful magnets to disturb this area of the brain and make people temporarily less moral.The study discovers that our sense of right and wrong isn't just based on upbringing,religion or philosophy-but also by the biology of our brains.
The researchers used a non-invasive technique to disrupt the area of the brain.The technique generates a magnetic field on a small part of the skull which creates weak electric currents in the brain.These currents interfere(干扰) with nearby brain cells and prevent them from firing normally.
One story described a man who let his girlfriend walk over a bridge he knew was unsafe.The girl survived unharmed.Under normal conditions,most people rate the man's behavior as unacceptable.But after getting the magnetic pulse,the volunteers tended to see nothing wrong with his actions-and judged his behavior purely on whether his girlfriend survived.
Another story described two girls visiting a chemical plant where one girl asks her friend to put sugar in her coffee.The friend uses powder from a jar marked toxic (有毒的)-but as the powder turns out to be sugar.Volunteers with a disrupted moral compass tended to rate the girl's behavior as permissible because her friend was not injured-even though she was aware the powder came from a jar labeled toxic.
Throughout the experiment,irresponsible or deliberate actions that might have resulted in harm were seen as morally acceptable if the story had a"happy ending".

30.The third paragraph mainly tells usA.
A.how the powerful magnets disrupt the area of the brain
B.what harm the powerful magnets bring to the brain
C.whether the powerful magnets can disrupt the area
D.how researchers spot the area with powerful magnets
31.What do the two stories want to tell us?B
A.People who like playing jokes on others is controlled by"moral compass".
B.People judge others'behavior acceptable or not by the"moral compass".
C.Whether people's behavior is acceptable or not is judged by a happy ending.

分析 本文是一篇科教类阅读,主要向人们介绍了大脑中一个控制我们判断他人行为的"道德指南区".
解答 29-31 BAB
29题答案:B考查细节推理,根据文章第一段的…how we judge other people's behavior.The region,which lies just behind the right ear,becomes more active when we think about other people's misdemeanor or good works."我们如何判断他人的行为,当我们考虑他人的____或好的工作时这个刚好位于右耳后方的区域会变得更加活跃"可知与"好的行为(工作)对应的是‘不好的行为'",故本题答案为B选项.
30题答案:A考查细节推理,第三段是以一个男孩让自己的女朋友过一座明知不安全的桥的例子来说明人们因为强大的磁力会做出错误的判断,这是因为磁力干扰了大脑;故本题答案为A选项.
31题答案:B考查细节推理,两个例子都是在说明人作出判断是基于我们大脑的生物反应(受moral compass的影响)而非教养、宗教或哲学;故本题答案为B选项.
点评 本文是一篇科教类阅读,题目涉及多道细节理解题,做题时结合原文和题目有针对 性找出相关语句进行仔细分析,结合选项选出正确答案.推理判断也是要在抓住关键句子的基础上合理的分析才能得出正确的答案.
