Question

    What will the car be like in the future? Maybe we can sit in a car that can drive itself.

About 40 years ago, scientists from the United States started to make self-driving cars (无人驾驶汽车). The most famous one was made by Google(谷歌) in 2009. There are cameras and radars (雷达) on the top of the car. They let the computer in the car draw a 3D map of the environment(环境). Chinese scientists have also successfully(成功地) made a self-driving car. The car made a trip from Changsha to Wuhan.

Is a self-driving car safe? A recent(最近的) study shows that robots(机器人) make safer drivers than people. If only 10% of cars on the street are self-driving, they will save 1,000 lives (生命) every year. If 90% of vehicles(交通工具) are self-driving, 21,700 lives will be saved(被救) a year. But a self-driving car is expensive and each costs about $100,000. So it is impossible to be very popular in the near future.

【解析】

本文是一篇说明文，主要讲述了未来的一种自主驾驶汽车,并详细介绍了这种汽车的功能以及应用前景。

1.主旨大意题。根据文章第一段第二句“Maybe we can sit in a car that can drive itself.”可知本文讲的是关于自己可以驾驶的气车，故选C。

2.细节理解题。根据文章第二段第二句“The most famous one was made by Google(谷歌) in 2009.”可知谷歌在2009年制造出了最著名的无人驾驶汽车，故选B。

3.细节理解题。根据文章第二段第三句“There are cameras and radars (雷达) on the top of the car.”可知在无人驾驶汽车的顶部安装了照相机和雷达，故选D。

4.细节理解题。根据文章最后一段倒数第二句“But a self-driving car is expensive and each costs about $100,000.”可知一辆无人驾驶汽车是非常昂贵的，要花费大约10万美元，故选A。

5.细节理解题。根据文章第二段第二句“The most famous one was made by Google(谷歌) in 2009.”可知最著名的无人驾驶汽车是谷歌在2009年制造的，不是40年前，所以A错误；根据文章第二段第四句“They let the computer in the car draw a 3D map of the environment(环境).”可知无人驾驶汽车里的电脑可以绘制周围环境的3D图像，不是汽车绘制，所以B错误；根据文章第二段最后一句“The car made a trip from Changsha to Wuhan.”可知中国研制的无人驾驶汽车从长沙开到了武汉，所以C正确；根据文章第三段的第三、四句“If only 10% of cars ...they will save 1,000 lives (生命) every year. If 90% of vehicles...21,700 lives will be saved(被救) a year.”可知路上无人驾驶汽车的比例不同，每年获救的人数是不一样的，不能一概而论，所以D错误。A、B、C、D四个选项中只有C正确，故选C。
