[解析]
(1)A.推理判断题。根据第二段While much of the debate so far has been focused on the safety of driverless cars(and rightfully so),policymakers also should be talking about how self﹣driving vehicles can help reduce traffic jams,cut emissions(排放) and offer more convenient,affordable mobility options.(虽然到目前为止,大部分辩论都集中在无人驾驶汽车的安全性上(这是理所应当的),但政策制定者也应该讨论无人驾驶汽车如何有助于减少交通拥堵、减少排放,并提供更方便、更实惠的出行选择。)可知,政策制定者应该讨论无人驾驶车怎么帮助削减交通阻塞,减少尾气排放,提供更方便、更便宜的出行选择,由此可见人们应该多关注无人驾驶车怎么帮助处理与交通有关的问题。故选A。
(2)C.推理判断题。根据文章第一段But however long it takes,the technology has the potential to change our transportation systems and our cities,for better or for worse,depending on how the transformation is regulated.(不管花多长时间,这项技术都有可能改变我们的交通系统和我们的城市,不管是好是坏,这取决于这种转变如何被规范。)再根据文章最后一句话The car of the future is coming.We just have to plan for it.(未来的汽车就要来了。我们只需要计划一下。)可知,我们需要为其做好计划,故作者的主要关注点是对这种转变的管理规范,故选C。
(3)B.词义猜测题。根据第四段The first commercially available driverless cars will almost certainly be fielded by ride﹣hailing services,considering the cost of self﹣driving technology as well as liability and maintenance issues(责任与维护问题).(鉴于自主驾驶的费用以及责任和维护问题,无人驾驶车几乎可以肯定将会被打车服务使用。)故划线词是"被应用"的意思。A.Replaced被取代;B.Employed被应用;C.Shared被分享;D.Reduced被减少。故选B。
(4)D.观点态度题。根据文章最后一段The coming technological advancement presents a chance for cities and states to develop transportation systems designed to move more people,and more affordably.The car of the future is coming.We just have to plan for it.(即将到来的技术进步为城市和州提供了发展交通系统的机会,以更经济实惠的方式运送更多的人。未来的汽车就要来了。我们只需要计划一下。)中的 advancement,move more people,and more affordably.以及plan for it可推知,作者是积极的态度。故选D。
