1．James Cooke，of Islip，N．Y．，can't recognize other people．"I see eyes，nose，cheekbones，but no face，"he said．"I've even passed by my son and daughter without recognizing them．"He is not the only one．Those with prosopagnosia，also known as face blindness，can see perfectly well，but their brains are unable to piece together the information needed to understand that a collection of features represents an individual's face．The condition is a neurological（神经病学的）mystery，but new research has shed light on this strange disease．
Some scientists had believed that faces and voices，the two main ways people recognize one another，were processed separately by the brain．Indeed，a condition parallel to prosopagnosia，called phonagnosia，similarly leaves a person unable to distinguish a familiar voice from an unfamiliar one．But by testing for these two conditions at the same time，researchers at the Max Planck Institute recently found evidence that face and voice recognition may be linked in a unique person-recognition system．
The scientists observed the brain activity of 19healthy volunteers as they were led through tasks that tested their ability to recognize both faces and voices．The researchers found that regions of the brain，associated with facial recognition，are directly linked to regions responsible for voice recognition．
This research helps explain why a person with prosopagnosia may still have difficulty determining who a person is even after he has begun to speak．The challenge for scientists is to find out where this system breaks down．Are these connections in the brain missing entirely，or are people unable to recognize faces and voices simply unable to use these links in some way？
It is unclear how many people have these conditions．Many don't even realize they have problems with facial or voice recognition．While some develop these difficulties after a brain injury，others develop it in childhood．

分析 本文属于说明文阅读，作者通过这篇文章主要向我们描述了有些人有面部和声音识别的问题，这其实是一种病，由大脑损伤引起，目前还没有治愈的方式．
解答 71．C．细节理解题．根据文章第二段"He is not the only one．Those with prosopagnosia，also known as face blindness"可知James Cooke不能认出别人是因为他患有脸盲症；故选C．
72．D．推理判断题．根据最后一段"It is unclear how many people have these conditions．Many don't even realize they have problems with facial or voice recognition"可知脸盲症目前还没有方式治愈；故选D．
73．A．词义猜测题．根据文章第三段"Indeed，a condition parallel to prosopagnosia，called phonagnosia，similarly leaves a person unable to distinguish a familiar voice from an unfamiliar one"可知词义为声音失明症；故选A．
74．C．细节理解题．根据文章第四段"The researchers found that regions of the brain，associated with facial recognition，are directly linked to regions responsible for voice recognition"可知大脑区域为个人识别相关；故选C．
75．C．推理判断题．根据最后一段"It is unclear how many people have these conditions．Many don't even realize they have problems with facial or voice recognition"可知有些人有面部和声音识别的问题；故选C．
点评 考察学生的细节理解和推理判断能力，做细节理解题时一定要找到文章中的原句，和题干进行比较，再做出正确的选择．在做推理判断题不要以个人的主观想象代替文章的事实，要根据文章事实进行合乎逻辑的推理判断．
