There’ s a 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 Systems, 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 reasonable that, within three to five years, we’ll have s0me 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 Sean, 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 dog’ s nose.The author’s attitude towards Larry Myers’ work is ______. A．cautiousB．approvingC．suspiciousD．overenthusiastic

题目解答
答案
B
解析
文章介绍了Larry Myers及其在Auburn University的Institute for Biological Detection Systems的工作，他们正在研发一种人工嗅觉设备，即“人工鼻子”。这种设备可以用于检测毒品、尸体、炸弹和食品污染等，具有广泛的应用前景。
步骤 2：分析作者态度
作者在描述这项技术时，提到了其潜在的革命性进步，如在公共安全和食品行业中的应用。同时，作者也提到了这种技术可能被滥用的风险，例如侵犯个人隐私。然而，作者并没有表现出对这项技术的怀疑或过度热情，而是以一种客观的态度来描述其潜在的利弊。
步骤 3：确定作者态度
根据文章内容，作者对Larry Myers的工作持支持态度，认为这项技术具有重要的应用价值，但同时也提醒了潜在的风险。因此，作者的态度是支持的，但同时保持谨慎。
