[解析]
(1)A.细节理解题。根据第一段中的"Say goodbye to standing in long lines holding boarding passes and other travel documents.Step this way,instead.Look into the camera lens and off you go."(告别拿着登机牌和其他旅行证件排着长队。往这边走,看一下摄像头,你就可以过去)以及第二段中的"Sound convenient?"(这听起来是不是很方便?)可知,有了面部识别系统,人们可以快速通过机场的安检,故A项正确。
(2)C.细节理解题。根据第六段中的"Editing such a big database,many worry,will inevitably (不可避免地)lead to privacy concerns down the road.The biggest drawback for facial recognition technology in most people's opinions is the threat to an individual's privacy."(编辑这么大的数据库,很多人担心,这将不可避免地导致隐私问题。在大多数人看来,面部识别技术最大的弊端是对个人隐私的威胁)可知,很多市民担心人脸识别技术会泄露他们的隐私,从而导致他们的个人信息被滥用,故C项正确。
(3)A.词义猜测题。根据划线词后的"At an airport,travelers are requested to present their passports,from which the software will determine whether the person standing in front of the camera matches the identity.If it matches,then they can get through quickly.However,the surveillance (监控)system searches a large database for the face presented to the camera.Editing such a big database,many worry,will inevitably (不可避免地)lead to privacy concerns down the road."可知,在机场,旅客被要求出示护照,软件将根据护照判断站在摄像机前的人是否与身份相符。如果匹配,那么他们可以很快通过。然而,监控系统会在一个大型数据库中搜索出现在摄像机面前的人脸。编辑这么大的数据库,很多人担心,这将不可避免地导致隐私问题,这个例子说明政府和市民之间就这项技术的使用发生了冲突,由此可知划线词词义为"冲突",A.Conflict冲突;B.Crisis危机;C.Challenge挑战;D.Consequence结果。故A项正确。
(4)B.观点态度题。根据最后一段中的"Regulating it,however,may be necessary to put an acceptable framework of rules around its use."(然而,对其进行规范可能有必要围绕其使用建立一个可接受的规则框架)可知,作者认为应该规范面部识别技术的使用,故B项正确。
