4、ed.The concern was based largely on an independent assessment of face-recognition systems carried out in 2000 in the U.S. by the Department of Defense.

Feed the software a series of mugshots and
7、itll calculate their faceprints. Then it can monitor live CCTV images for the faces of known suspects. When it finds a match, it raises an alarm.Even if the system does manage to capture a face, the problems arent over. The trouble is that a suspects faceprint taken from live CCTV is unlikely to mat
8、ch the one in the database in every detail.

But theres a price to pay: the more potential suspects you pick up, the more false alarms yo
9、u get. You have to get the balance just right.Despite the disappointing tests, some people insist that face-recognition technology is good enough to put terrorists off. After all the claims and counter-claims, with no one able to discern the truth, the industry may soon have to face up to reality.1.

15、turer, issued a fact sheet explaining how its technology could enhance airport security (9月11日之后，领先的制造商Visionics发布了一份情况说明书，解释其技术如何增强机场安全)。但并不能证明A项跟D项正确。第三句说到: The companys share price skyrocketed (公司股价飞涨)。因此B项正确。最后一句指出: airports across the globe began installing the software and running trials (全球各地的机场开始安装该软件并进行测试)。但这并不能说明C项正确。因此答案为B。第2题:判断推理题。第二段意思为:然而，伴随软件试用结果出现，该软件的光彩逐渐消逝，无论你或许对面部识别软件听说过什么，Visionics这家大公司的面部识别软件都不如宣传的那样好。因此C项“该软件结果是无效率的”正确。第3题:判断推理题。题干问的是:根据美国国防部的说法，这个系统的致命缺点是什么? A:太多假警报被拉响。B:每个人都要直视镜头。C:只有90%的嫌疑犯在机场被发现。D:每个人都应该伪装自己。可定位至第三段。第二句指出: These tests fou
