　　【解题导语】　本文是一篇说明文。文章主要介绍了一种高科技的新产品——无人驾驶的车。无人驾驶的车在有些地方已经被政府允许试用，而这种车的模式设计也会让车在行驶的时候更加高效并且更安全。但目前遇到的最大挑战就是造价太高了。

　　6．What can we learn from Paragraph 1?

　　A．Driverless vehicles are now legal in the whole USA.

　　B．Volvo will be the first to sell driverless cars.

　　C．Driverless cars are pointing us a faraway future.

　　D．Google’s self­driving cars have covered a long distance.

　　解析：选D。推理判断题。根据第一段中的“The high­tech company Google has a number of self­driving cars，which had covered 480,000 kilometers by August.”可知，谷歌公司有大量的自动驾驶的车，而且截止8月，已经行驶过480 000千米。由此可判断这种自动驾驶的车已经行驶了很长一段距离。故选D。
