Self-driving cars are believed to be the future of driving. Companies including Toyota, Uber and Google are all competing to be the first to bring them to the market. However, car-makers need to solve one problem first: 1
Most drivers today use gestures to show their intentions. They wave a car into a lane (车道), or nod at passers-by and cyclists, to let them cross. 2 So what can they do? The US car-maker Ford and its partner Virginia Tech think they have the answer, according to Business Insider.
3 For example, if a driverless car is giving way, it could flash two white lights side to side. A solid white light would tell people nearby that there are no humans in the car. A slow blinking light would show the car is coming to a stop. 4 To test the method on real roads, the team designed a special suit that looks exactly like a car seat. When a driver wears it, it looks like the car is driverless.
The team successfully collected more than 1,500 hours of data after about 2,900 kilometers of “self-driving” through busy cities. 5 Ford says it plans to share the data with 11 other car-makers, according to DOGO News. Ford hopes that in the future, every car-maker will use the same system of signals.
A.But self-driving cars don’t have this ability.
B.It’s a test for the company’s self-driving technology.
C.The data recorded how people interacted with a driverless vehicle.
D.How driverless cars communicate with passers-by, bikers and other drivers.
E.A rapidly flashing light would tell passers-by that a car is about to speed up.
F.More than one-third of them are worried about the safety of self-driving cars.
G.The team is testing a method that uses light signals to show what self-driving cars are doing.
答案
[语篇解读] 无人驾驶汽车如何和行人、骑自行车的人以及其他司机交流呢?美国汽车制造商Ford和其合作者Virginia Tech 找到了一个办法:使用光信号来表示无人驾驶汽车要做什么。
1.D 上一句提到:汽车制造商需要首先解决一个问题,故该空应该是一个问题。选项中只有D选项是问题:无人驾驶汽车如何与行人、骑自行车的人以及其他司机交流?
2.A 上一句提到:今天,大部分司机使用手势来表达他们的意图。他们挥手让一辆车进入车道或者向过路人、骑自行车的人点头让他们通过。下一句提到:那么,他们能做什么?该空承上启下,应表示无人驾驶汽车不能像司机那么做。故A选项正确。
3.G 下一句是个例子:如果无人驾驶汽车要让路的话,它可以来回闪动两个白灯。由这个例子可知,汽车制造商的解决办法应该是使用光信号来表示无人驾驶汽车要做什么。故G选项正确。
4.E 考查上下文理解和逻辑推理能力。上文举了两个例子来说明无人驾驶汽车如何利用光信号来表示无人驾驶汽车要做什么。该空承接上文,应该也是类似例子。故E选项正确:快速的闪光告诉行人汽车要准备加速。
5.C 上一句提到:这个团队成功地搜集了1,500多个小时的数据。承接该句中的“data”,C选项正确:这些数据记录了人们如何和无人驾驶汽车互动。
