六、阅读与回答问题(共5小题;每小题2分,满分10分)
Have you ever seen a car without a driver? It sounds crazy, but these computer - driven driverless cars will soon be filling roads near you. Companies have been designing and testing these cars, and they just need to see if they are value for money, work out insurance (保险) issues, and run final tests to check if they can run alongside human - driven cars on the road.
So how do they work? The cars have sensors (感应器) all around which can find other cars and objects in the road. Sensors on the wheels also help when you park, so the car knows how far it is from the outside of the road or other parked cars. Road signs are read by cameras, and satellite navigation systems are used, so the car knows how to get where you want to go. All you have to do is type in the address! Finally, a central computer system takes in all the information that it receives from the sensors and cameras and works out when to speed up, stop and turn.
Sound like your idea of a fantasy world? Sitting back, looking out of the windows and even watching a film or reading a book while “driving” would be possible with this new technology. You wouldn't have to worry about remembering directions to where you're going. In addition, computers would be better drivers than humans—they would obey the speed limit and have quicker action times when in dangerous situations.
However, there are many disadvantages of driverless cars. Computers would have difficulty making ethical (道德的) decisions: if a child ran into the road, would the computer choose to hit the child or change the direction suddenly and potentially hurt the car's passengers? Moreover, I personally find driving fun—I'd miss driving a car myself. There would also be many other decisions to be made—should children, or drunken people, be allowed in a driverless car by themselves? Or would there need to be a person with a driving license in the car at all times?
Although being driven around by a machine would perhaps mean that no one needs a driving license, and saving money for everyone, many people would be put out of a job when driverless cars appear. Bus, taxi and train drivers as well as driving instructors would be made unnecessary.
I'm not certain I'd want a driverless car—but it's only a matter of time before they'll become more affordable and common on our roads.
66. If you use a computer - driven driverless car, what should you do to get where you want to go?
67. How can the computer - driven driverless cars read road signs?
68. What can sensors on the wheels do?
69. What are the disadvantages of driverless cars?
70. Do you hope these computer - driven driverless cars will soon be filling roads near you? Why? (请自拟一句话作答)
