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 like Google and Tesla have been designing and testing these cars, and the technology is there.

So how? The cars have sensors(感应器)all around which can find other cars and objects in the road. Road signs are read by cameras, and satellite navigation systems(卫星导航系统)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 heaven(天堂)? 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 also drive more safely than people — they would obey the rules and have quicker action times when in dangerous situations.

However, there are many drawbacks of driverless cars. Computers would have difficulties making ethical(道德的)decisions: if a child ran into the road, would the computer choose to hit the child or turn suddenly and potentially kill the car’s passengers? Moreover, I personally find driving fun –I’d miss never driving a car myself. There would also be many other decisions to be made –should children, or drunk 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?

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 popular on our roads.

1.When using a driverless car, you need only .

A. read the road signs carefully B. check the cameras

C. put the address into the computer D. remember the directions

2.The third paragraph mainly tells us about the of driverless cars.

A. instructions B. standards C. advantages D. tests

3.The underlined word “potentially” in Paragraph 4 means “ “.

A. possibly B. successfully C. especially D. naturally

4.What’s the writer’s opinion about future driverless cars?

A. They’ll cause more accidents. B. They’ll be less expensive.

C. They’ll use less energy. D. They’ll run much faster.

The winter of 1948 was very difficult for our family of eight living in Knoxvile, Tennessee. Unfortunately, Dad became ill and soon was out of a job. I was only 8 years old and my younger brother, Buddy was 7. After school we went to pick coal(煤) that fell from the coal train along the railroad near our home. When the train slowed down, we ran alongside it. After the train passed, we picked up the fallen coal.

One day, the train stopped for a short time unusually. My brother and I were digging around in the snow when the train's fireman came to the window and shouted to us, “Why are you boys digging in the snow? Are you looking for gold?” he laughed.

“No, sir,” I replied, “We are finding coal.”

“Why doesn't your daddy buy coal? It's really dangerous here.”

“Our daddy is very sick and we have no money to buy food and coal,” I answered.

The fireman turned and went inside. After a moment, he shouted again. “Hey! Bring that coal bucket(桶子) here. I got something for you.” Then the fireman filled our bucket with clean coal. We were happy with his gift, and we knew we could go home early that day.

He smiled the kindest and warmest smile I had ever seen. “You two boys come here the day after tomorrow and I'll throw off some coal.”

Two days later, Buddy and I stood by the railroads as the train slowed down. The fireman waved to us, then disappeared. Suddenly, some coal and a piece of red cloth came out. In the red cloth were two pieces of bubble gum(泡泡糖) and a new one-dollar bill.

All that winter, three days a week, we received a bucket of coal, a gift and, sometimes, money. I never knew the person's full name, but to our family, he was a guardian angel.
