Question

9．

Ask Dr？Jeffers	This 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（受試者）were connected to scanning equipment and shown two numbers on a screen．They were then asked to choose between adding or subtra cting（減）the two numbers．Using this method，researchers were able to follow brain processes and make the correct assumptions（假設）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．

Answer 1

分析 本文是一篇報刊新聞，大意是說本月內腦科專家Jeffers博士將做客本報心理咨詢欄目，回答讀者提出有關大腦及它的工作原理等問題．問題一：科學家們正學習用電腦來"讀懂人的心思"，這是真實的嗎？回答：到目前為止，在這個領域做過很多研究和嘗試，但大腦掃描設備和相應的計算機程序并不能真正"讀懂心思"；問題二：我三歲的兒子喜歡我胳肢他，直到他笑得無法忍受，而他自己做這個動作時卻無法達到這個效果，這是為什么呢？回答：當我們預期或期盼著某事發(fā)生時，大腦會忽略身體上的感覺，而一旦一些無法預知的感覺突然發(fā)生時，人會產生輕微的恐慌的反應．

解答 46．B     推理判斷．根據第一個問題的應答的最后一句"It's not quite mind reading，but it's certainly a first step．"可以推斷，它不完全是‘測心術/讀心術/心智解讀'，這當然是第一步，故選B．
47．A     推理判斷．由問題二的應答句中"but it causes a mildpanic reaction when there is an unexpected feeling．"可知，當無法預知的感覺突然發(fā)生時，人會產生輕微的恐慌的反應，故選A．
48．B     推理判斷．根據問題二"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博士提出了這樣的問題"我三歲的兒子喜歡我胳肢他，直到他笑得無法忍受，而他自己做這個動作時卻無法達到這個效果，這是為什么呢？"，故本題選B．
49．C     推理判斷．根據本報道的欄目"Ask Dr？Jeffers  This month Dr． Jeffers is answering questions about the human brain and how it works．"可知，本月內腦科專家Jeffers博士將做客本報心理咨詢欄目，回答讀者提出有關大腦及它的工作原理等問題，故選C．

點評 解答細節(jié)理解題時，一個常用的方法就是運用定位法，即根據題干和選項中的關鍵詞從原文中找到相關的句子，與選項進行比較從而確定答案；推理判斷題既要求學生透過文章表面文字信息推測文章隱含意思，又要求學生對作者的態(tài)度、意圖及文章細節(jié)的發(fā)展作正確的推理判斷，力求從作者的角度去考慮，不要固守自己的看法或觀點．
