Question

11．首先阅读下列文章的提示性图片及简介：

A		By combing through newly digitized census data from the 19th century，J．David Hacker，a demographic historian from Binghamton University in New York，has recalculated the deathtoll and increased it by more than 20 percent-to 750，000．
B		Called the iBrain，this simple-looking contraption is part of an experiment that aims to allow Dr．Hawking-long paralyzed by amyotrophic lateral sclerosis，or Lou Gehrig's disease-to communicate by merely thinking．
C		What we wear can affect not only what people think of us，but also the way our brains work，a study involving a doctor's coat shows．
D		Even after 20 years of studying in the country，Brian L．Fisher，an entomologist，was surprised by the ability of a cyclone to derail an expedition．
E		A Canadian project aimed at creating a genetically engineered pig whose manure would be less harmful to the environment is being halted after failure to find a company willing to bring the animal to market，according to the lead researcher．
F		Scientists have for the first time identified several gene mutations that they say sharply increase the chances of autism，and have found that the risk increases with the age of the parents，particularly the father．

以下是文章的标题，请将相关文章的标题与文章的提示性图片及简介匹配起来．
46．Move to Market Gene-Altered Pigs in Canada Is HaltedE
47．Mind Games：Sometimes a White Coat Isn't Just a White CoatC

Answer 1

分析 本文介绍了几个新闻．A：J．David Hacker重新评估了内战的死亡人数，增加了百分之二十，达到七十五万；
B：一个可以读懂我们思维的小装置，它可以让像霍金这样的人通过思维和别人交流；
C：我们的穿着不仅影响别人怎么看我们，而且影响我们的大脑的思维；
D：Brian L．Fisher吃惊于一个气旋破坏探险的能力；
E：转基因猪在投入市场的时候失败了；
F：基因变异和患自闭症的风险之间的关系．

解答 46 E．根据46题可知转基因猪在投入市场的时候失败了，所以答案是E，因为其中提到A Canadian project aimed at creating a genetically engineered pig whose manure would be less harmful to the environment is being halted．
47．C．根据47题可知有时候一件白衬衫不仅仅是一件白衬衫，它还代表别的意义，所以答案是C，因为其中提到What we wear can affect not only what people think of us，but also the way our brains work：48．B．根据48题可知这是一个可以读懂我们思维的小装置，所以答案是B，因为其中提到allow Dr．Hawking-long paralyzed by amyotrophic lateral sclerosis，or Lou Gehrig's disease-to communicate by merely thinking．（可以让像霍金这样的人通过思维和别人交流）．
49．F．根据49题可知基因变异和患自闭症的风险之间的关系，所以答案是F，因为其中提到Scientists have for the first time identified several gene mutations that they say sharply increase the chances of autism（科学家第一次确定几种基因突变会增加患自闭症可能性）．
50．A．根据50题可知对于死亡人数的估计提高了，所以答案是A，因为其中提到has recalculated the deathtoll and increased it by more than 20 percent-to 750，000．（他重新评估了死亡人数，增加了百分之二十，达到七十五万）
