There’s simple premise behind what Larry Myers does for a living: If you can smell it, you can find it. Myers is the founder of Auburn University’s Institute for Biological Detection System, the main task of which is to chase the ultimate in detection devices—an artificial nose. For now, the subject of their research is little more than a stack of gleaming chips tucked away in a laboratory drawer. But soon, such a tool could be hanging from the belts of police, arson(纵火)investigators and food-safety inspectors.
The technology that they are working on would suggest quite reasonably that, within three to five years, we’ll have some workable sensors ready to use. Such devices might find wide use in places that attract terrorists. Police could detect drugs, bodies and bombs hidden in cars, while food inspectors could easily test food and water for contamination.
The implications for revolutionary advances in public safety and the food industry are astonishing. But so, too, are the possibilities for abuse: Such machines could determine whether a woman is ovulating(排卵), without a physical exam—or even her knowledge. One of the traditional protectors of American liberty is that it has been impossible to search everyone. That’s getting not to be the case.
Artificial biosensors created at Auburn work totally differently from anything ever seen before. Aroma Scan, for example, is a desktop machine based on a bank of chips sensitive to specific chemicals that evaporate into the air. As air is sucked into the machine, chemicals pass over the sensor surfaces and produce changes in the electrical current flowing through them. Those current changes are logged into a computer that sorts out odors based on their electrical signatures. Myers says they expect to load a single fingernail-size chip with thousands of odor receptors(感受器), enough to create a sensor that’s nearly as sensitive as a dog’s nose.
1. Which of the following is within the capacity of the artificial nose being developed?
2. A potential problem which might be caused by the use of an artificial nose is ______.

第1题:
【选项释义】
Which of the following is within the capacity of the artificial nose being developed? 下列哪项在正在研制的人工鼻子的能力范围内?
A. Performing physical examinations. A. 进行体检。
B. Locating places which attract terrorists. B. 确定吸引恐怖分子的地方。
C. Detecting drugs and water contamination. C. 检测药物和水污染。
D. Monitoring food processing. D. 监控食品加工过程。
【答案】C
【考查点】事实细节题
【解题思路】文章第二段提到:Police could detect drugs, bodies and bombs hidden in cars, while food inspectors could easily test food and water for contamination.(警察可以发现藏在汽车里的毒品、尸体和炸弹,而食品检查员可以很容易地检测食品和水的污染)可知人工鼻可被用于检测药物和水污染;故选C。
【干扰项排除】
A选项physical examinations在第三段中提到,但与题干无关,属于出处错位;
B选项,文中提到的信息是:Such devices might find wide use in places that attract terrorists.(这类装置可能会在吸引恐怖分子的地方得到广泛使用。)而不是确定吸引恐怖分子的地方,属于曲解原文;
D选项,根据解析可知,文中说的是检测出食品的污染而不是食品的加工过程,属于偷换概念。
第2题:
【选项释义】
A potential problem which might be caused by the use of an artificial nose is______. 使用人造鼻子可能会引起的一个潜在问题是______。
A. negligence of public safety A. 公共安全的疏忽
B. an abuse of personal freedom B. 人身自由的滥用
C. a hazard to physical health C. 对身体健康的危害
D. a threat to individual privacy D. 个人隐私的威胁
【答案】D
【考查点】推理判断题
【解题思路】文章第三段Such machines could determine whether a woman is ovulating, without a physical exam—or even her knowledge.(这种机器可以在不需要身体检查甚至不需要本人知情的情况下,就能判断出一个女人是否在排卵。)排卵是个人隐私,推知使用人造鼻子可能引起的一个潜在问题是对个人隐私的威胁;故选D。
【干扰项排除】A、B、C选项在文中没有提及,属于无中生有。
第3题:
【选项释义】
To produce artificial noses for practical use, it is essential______. 为了生产实际使用的人造鼻子,______是必不可少的。
A. to develop microchịps with thousands of odor receptors A. 开发有数千个气味感受器的微芯片
B. to invent chips sensitive to various chemicals B. 发明对各种化学物质敏感的芯片
C. to design a computer program to sort out smells C. 设计一个计算机程序来分类气味
D. to find chemicals that can alter the electrical current passing through D. 寻找可以改变通过的电流的化学物质
【答案】A
【考查点】事实细节题
【解题思路】根据文章最后一句:Myers says they expect to load a single fingernail-size chip with thousands of odor receptors, enough to create a sensor that’s nearly as sensitive as a dog’s nose.(迈尔斯说,他们希望在一个指甲盖大小的芯片上植入数千个气味感受器,这样足以制造出一种几乎和狗鼻子一样灵敏的传感器。)其中microchips是fingernail-size chips的同义替换,可知为了生产实用的人工鼻子,需要研制具有数千个感受器的微芯片;故选A。
【干扰项排除】
B选项根据解析可知,属于曲解原文;
C选项是制造芯片的过程,而不是制造人造鼻子的必要过程,属于张冠李戴;
D选项,文中说的是:As air is sucked into the machine, chemicals pass over the sensor surfaces and produce changes in the electrical current flowing through them.(当空气被吸入机器时,化学物质通过传感器表面,并在流过传感器表面的电流中产生变化。)可知空气中的化学物质可以通过传感器产生电流,是不需要去寻找的,属于曲解原文。
第4题:
【选项释义】
The author’s attitude towards Larry Myers’s works is______. 作者对Larry Myers作品的态度是______。
A. cautious A. 谨慎的
B. approving B. 赞同的
C. suspicious C. 怀疑的
D. overenthusiastic D. 过分热情的
【答案】A
【考查点】观点态度题
【解题思路】纵观全文,文章前半部分说人造鼻子对公共安全和食品工业的革命性进步的影响是惊人的;接着对其进行了批评,称这个发明的滥用会侵犯隐私,可知作者对这个发明既褒又贬,因此是谨慎和持观望态度的,故选A。
【干扰项排除】B、C、D选项不能通过文章信息推断出来。
