For Self-driving Cars, Car Washes are a Nightmare

Car washes have been automated for decades, but companies developing fully self-driving vehicles must rely on a human touch to keep their cars and trucks in working condition.

【1】 For example, soap remainder or water spots could effectively “blind” a self-driving car. A traditional car wash’s heavy brushes could jar the vehicle’s sensors, disturbing their standardization and accuracy. Even worse, sensors, which can cost over $100,000, could be broken. 【2】 Dirt, dead bugs, bird droppings or water spots can impact the vehicle’s ability to drive safely.

Avis, which has years of experience managing rental cars, has been tasked with cleaning and refueling the self-driving vans of Waymo, the self-driving arm of Google’s parent company. Avis chief innovation officer Arthur Ordua told CNN, “There are special processes that definitely require a lot more care and focus, and you have to clean the vans quite often.”

【3】 But other self-driving car companies such as Toyota, Aptiv, Drive, AI and Uber described to CNN that they use microfiber (微纤维) cloths along with rubbing alcohol, water or glass cleaner for manual cleanings.

【4】 This should ease some need for manual cleaning. But because self-driving vehicles can have dozens of sensors, Seeva CEO Diane Lansinger doesn’t imagine products like this will be able to clean every camera, radar or LIDAR, a laser sensor that most experts see as essential for self-driving vehicles.

A. The sensors on a fully self-driving car require special care.

B. Ordua wouldn’t reveal exactly how they’re washing the vehicles.

C. The most advanced cars on the planet require an old-fashioned handwashing.

D. Meanwhile, some companies, such as Cruise, are building sensor cleaning equipment into their vehicles.

E. There are a range of problems with putting a self-driving vehicle through a traditional car wash, experts say.

F. A self-driving vehicle’s external needs to be cleaned even more frequently than a typical car because the sensors must remain free of obstacles.

Answer 1

【答案】

【1】E

【2】F

【3】B

【4】D

【解析】

本文是一篇说明文，介绍了自动驾驶汽车面临的洗车难问题。

【1】空后说例如，肥皂残留物或水渍可以有效地“蒙蔽”自动驾驶汽车，这是对空处的举例说明，因此此处是说自动驾驶汽车在洗车时存在一定的问题，故E项（专家表示，让自动驾驶汽车接受传统的洗车服务存在一系列问题）符合语境。

【2】空后说灰尘、死虫子、鸟粪或水渍会影响车辆的安全驾驶能力，因此此处是说自动驾驶汽车需要经常清洗，故F项（自动驾驶汽车的外部需要比普通汽车更频繁地进行清洁，因为传感器必须保持畅通）符合语境。

【3】空后说但丰田、Aptiv、Drive、AI和Uber等其他自动驾驶汽车公司向CNN表示，它们使用超细纤维布和酒精、水或玻璃清洁剂进行手动清洗，此处讲的还是关于汽车公司清洗自动驾驶汽车的情况，并与下文形成转折关系，故B项（奥杜纳不愿透露他们是如何清洗车辆的）符合语境。

【4】空后说这样可以减少一些手动清洗的需要，但是，由于自动驾驶汽车可以有几十个传感器，Seeva首席执行官戴安兰辛格并不认为这样的产品能够清洁每一个传感器，因此此处讲的是汽车公司为清洗自动驾驶汽车上的传感器所做的努力，故D项（与此同时，一些公司，如克鲁斯，正在他们的车辆上安装传感器清洁设备）符合语境。

在六选四的解题过程中，空后出现的for example, for instance往往是重要线索，例如本篇第1题，根据空后的“For example, soap remainder or water spots could effectively “blind” a self-driving car.”可知，例如，肥皂残留物或水渍可以有效地“蒙蔽”自动驾驶汽车，“For example”表明这是对空处的举例说明，因此此处是说自动驾驶汽车在洗车时存在一定的问题，故E项（专家表示，让自动驾驶汽车接受传统的洗车服务存在一系列问题）符合语境。
