  Ask Dr?JeffersThis month Dr.Jeffers is answering questions about the human brain and how it works.
Dear Dr.Jeffers,
One of my colleagues,Felix Moeller,told me that scientists are learning to use computer to‘read minds'.Is there any truth to this story/
-Jane Leon,New York,USA
Dear Ms.Leon,
Well,a lot of research is being conducted in this area,but so far,the brain scanning equipment and corresponding computer programs haven't been able to actually read thoughts.In one experiment,tes t subjects(受试者)were connected to scanning equipment and shown two numbers on a screen.They were then asked to choose between adding or subtra cting(减)the two numbers.Using this method,researchers were able to follow brain processes and make the correct assumptions(假设)70 percent of the time.It's not quite mind reading,but it's certainly a first step.
-Dr.J.
Dear Dr.Jeffers,
My three-year-old son loves it when I dig my fingers into his sides and tickle (胳肢)him until he laughs uncontrollably.The other day I noticed him trying to tickle himself but he couldn't do it.Why not?
-Glenn Lewis,Vancouver,Canada
Dear Mr.Lewis,
It's because of how the brain works.The brain is trained to know what to pay attention to and what to ignore.It causes us to ignore physical feelings we expect to happen,but it causes a mild panic reaction when there is an unexpected feeling.For example,you don't notice how your shoulder feels while you're walking down the street.But if someone comes up behind you and touches you lightly on the shoulder,you may jump in fear.It's that unexpected part that causes the tickle reaction.
-Dr.J.

分析 本文是一篇报刊新闻,大意是说本月内脑科专家Jeffers博士将做客本报心理咨询栏目,回答读者提出有关大脑及它的工作原理等问题.问题一:科学家们正学习用电脑来"读懂人的心思",这是真实的吗?回答:到目前为止,在这个领域做过很多研究和尝试,但大脑扫描设备和相应的计算机程序并不能真正"读懂心思";问题二:我三岁的儿子喜欢我胳肢他,直到他笑得无法忍受,而他自己做这个动作时却无法达到这个效果,这是为什么呢?回答:当我们预期或期盼着某事发生时,大脑会忽略身体上的感觉,而一旦一些无法预知的感觉突然发生时,人会产生轻微的恐慌的反应.

解答 46.B     推理判断.根据第一个问题的应答的最后一句"It's not quite mind reading,but it's certainly a first step."可以推断,它不完全是‘测心术/读心术/心智解读',这当然是第一步,故选B.
47.A     推理判断.由问题二的应答句中"but it causes a mildpanic reaction when there is an unexpected feeling."可知,当无法预知的感觉突然发生时,人会产生轻微的恐慌的反应,故选A.
48.B     推理判断.根据问题二"My three-year-old son loves it when I dig my fingers into his sides and tickle (胳肢)him until he laughs uncontrollably.The other day I noticed him trying to tickle himself but he couldn't do it.Why not?-Glenn Lewis,Vancouver,Canada   Dear Mr.Lewis"可知,是‘Dear Mr.Lewis向Jeffers博士提出了这样的问题"我三岁的儿子喜欢我胳肢他,直到他笑得无法忍受,而他自己做这个动作时却无法达到这个效果,这是为什么呢?",故本题选B.
49.C     推理判断.根据本报道的栏目"Ask Dr?Jeffers  This month Dr. Jeffers is answering questions about the human brain and how it works."可知,本月内脑科专家Jeffers博士将做客本报心理咨询栏目,回答读者提出有关大脑及它的工作原理等问题,故选C.

点评 解答细节理解题时,一个常用的方法就是运用定位法,即根据题干和选项中的关键词从原文中找到相关的句子,与选项进行比较从而确定答案;推理判断题既要求学生透过文章表面文字信息推测文章隐含意思,又要求学生对作者的态度、意图及文章细节的发展作正确的推理判断,力求从作者的角度去考虑,不要固守自己的看法或观点.

4.It was once common to regard Britain as a society with class distinction.Each class had unique characteristics.
In recent years,many writers have begun to speak the'decline of class'and'classless society'in Britain.And in modern day consumer society everyone is considered to be middle class.
But pronouncing the death of class is too early.A recent wide-ranging society of public opinion found 90percent of people still placing themselves in particular class; 73percent agreed that class was still a vital part of British society; and 52percent thought there were still sharp class differences.Thus,class may not be culturally and politically obvious,yet it remains an important part of British society.Britain seems to have a love ofstratification.
One unchanging aspect of a British person's class position is accent.The words a person speaks tell her or his class.A study of British accents during 1970s found that a voice sounding like a BBC newsreader was viewed as the most attractive voice,Most people said this accent sounded'educated'and'soft'.The accents placed at the bottom in this study,on the other hand,were regional(地区的)city accents.These accents were seen as'common'and'ugly'.However,a similar study of British accents in the US turned these results upside down and placed some regional accents as the most attractive and BBC English as the least.This suggests that British attitudes towards accent have deep roots and are based on class prejudice.
In recent years,however,young upper middle-class people in London,have begun to adopt some regional accents,in order to hide their class origins.This is an indication of class becoming unnoticed.However,the 1995pop song'Common People'puts forward the view that though a middle-class person may'want to live like common people'they can never appreciate the reality of a working-class life.
