题目内容
2.What will the car be like in the future?Maybe we can sit in a car that can drive itself.About 40years ago,scientists from the United States started to develop self-driving cars (无人驾驶汽车).The most famous recent one was made by Google in 2009.There are cameras and radars (雷达) on the top of the car.They allow the computer in the car to draw a 3D map of the environment.Chinese scientists have also successfully developed a self-driving car.The car made a trip from Changsha to Wuhan.
Is a self-driving car safe?A recent study shows that robots make safer drivers than humans.If only 10% of cars on the street are self-driving,they will save 1,000lives (生命) every year.If 90% of vehicles (交通工具) are self-driving,21,700lives will be saved a year.However,a self-driving car is expensive and each costs about $100,000.So it is impossible to be very popular in the near future.

分析 短文大意:
未来的汽车将会是什么样子?也许我们可以坐在一辆自动驾驶的汽车上.
大约40年前,来自美国的科学家开始开发自动驾驶汽车(无人驾驶汽车).最近的最有名的一辆是由谷歌在2009开发的.在汽车顶部有摄像头和雷达.他们允许汽车上的计算机画一个三维地图的环境.在中国科学家们成功的研发出了一种自主驾驶汽车.这辆汽车从长沙到武汉做了一次旅行.
无人驾驶汽车安全吗?最近的一项研究表明,机器人比人类驾驶汽车更安全.如果马路上有10%的汽车是无人驾驶的汽车,他们每年会挽救1000个人的生命.如果马路上90%的交通工具是无人驾驶的,每年会有21700个生命被挽救.可是,无人驾驶汽车现在非常的昂贵,每辆要花100000美元.在不远的将来,自主驾驶汽车不会很流行.
解答 31:B.分析计算题.根据About 40 years ago,scientists from the United States started to develop self-driving cars (无人驾驶汽车).可知,美国科学家在2009年开始研发自主驾驶汽车的描述错误.故选B.
32.B:细节理解题.根据The most famous recent one was made by Google in 2009.There are cameras and radars (雷达) on the top of the car.可知,通过谷歌,相机和微电脑在自主驾驶汽车顶部的描述错误.故选B.
33.A:细节理解题.根据Chinese scientists have also successfully developed a self-driving car.可知,在中国科学家们成功的研发出了一种自主驾驶汽车的描述正确.故选A.
34.A:细节理解题.根据If only 10% of cars on the street are self-driving,they will save 1,000 lives (生命) every year.可知大街上的自主驾驶汽车越多,交通死亡人数就越少描述正确.故选A.
35.B:细节理解题.根据So it is impossible to be very popular in the near future.可知,在不远的将来,自主驾驶汽车将会很流行的描述错误.故选B.
