[解析]
(1)B.推理判断题.根据第三段中的"And they believe the high﹣speed,low ﹣delay (低延迟的) nature of 5 G will improve driverless cars to the point where they will be safer than the cars being driven today."(研究人员相信5 G的高速、低延迟的特性将提高无人驾驶汽车的安全性,使之比现在驾驶的汽车更安全)"及第四段"Dr Dimitrios,a member of the research group,said, "To have a better idea of what the future will look like,think of having cars that not only use sensors to find what's around them,but also can talk to each other about safety information nearby."(研究小组成员迪米特里奥斯博士说,未来通过5 G技术,汽车不仅利用传感器来了解周围的情况,还能相互交流附近的安全信息)可知,迪米特里奥斯认为5 G技术将提高汽车驾驶的安全性,故B项正确.
(2)C.细节理解题.根据第四段中的"talk to each other about safety information nearby"(相互交流附近的安全信息)及第五段中的"so they could have changed their speed or,if possible,even avoided that route (路线) altogether"(这样就可以改变车速,甚至完全避开那条路线)可知,通过5 G技术,汽车能够为附近的车辆发出警告、改变车速或改变路线,而不是靠近危险区域,故C项正确.
(3)B.词句猜测题.根据划线词前的"5 G is an exciting mobile technology"可知,5 G是一项激动人心的移动技术,此处是说它的作用﹣﹣极大地推动智能城市和无人驾驶汽车的发展,由此可知划线词词义为"推动",A.Recovery恢复;B.Push推动;C.Danger危险;D.Fame名声.故B项正确.
(4)A.文章出处题.通读全文,特别是根据第一段"Cars could be able to "talk" to each other to warn about dangers on the roads using 5 G technology in future,according to researchers."(研究人员称,未来通过5 G技术,汽车可以相互"交谈"以警告道路上的危险)及第三段中的"And they believe the high﹣speed,low ﹣delay (低延迟的) nature of 5 G will improve driverless cars to the point where they will be safer than the cars being driven today."(他们相信5 G的高速、低延迟的特性将提高无人驾驶汽车的安全性,使之比现在驾驶的汽车更安全)可知,本文主要介绍的是未来,汽车可以通过5 G技术相互"交谈"以警告道路上的危险,这将大大提高无人驾驶汽车的安全性,这一话题属于科技范畴,因此文章最有可能出自报纸的科技板块,A.Science and Technology科技;B.Entertainment娱乐;C.Life生活;D.Transport运输.故A项正确.
