911.You are driving to school.You look up to see a pretty hot-air balloon.Whoa!You almost went through a stop sign!In a driverless car,you can look at the balloon.The car sees the stop sign without your help and stops the jye.ai.Car makers and others are already testing driverless cars or AVs (automated vehicles) in the U.S.jye.ai other countries.
Most cars already have some driverless technology like the anti-lock braking system (ABS).When a car is slipping on an icy road,the ABS can tap the brakes quickly.The wheels turn slowly but do not stop.The driver can then control the car safely.Many cars also have parallel parking technology.These cars can park themselves along a street.No driver is needed.
A driverless car can see the road better than people with the help of radar,cameras,and lasers.Radar helps the car see things up to 100 meters away even in darkness or rain.Cameras help the car see objects that are close.Lasers that work like radar,called lidar,spin on the roof and build a 3 D model of the world around the car.Automated vehicles use GPS to find the best way from one place to another.All the information from the radar,cameras,lasers,and the GPS goes to the Controller Area Network bus,which lets all those devices talk to one anojye.air.The CAN bus uses the information to direct the car and to tell the car to go or stop.
Problems still exist with AVs.Hackers(黑客) may take over the car.There will probably be fewer jobs for people who drive taxis and trucks.A robo-taxi can find you and take you to your destination without a taxi driver.Automated trucks may roll along highways without a truck driver.
In the future,you can be the driver of your car,or you can look out of the window while the car drives you.

A funny thing happened to Arthur when he was on the way to work one day.As he walked along Park Avenue near the First National Bank,he heard the sound of someone trying to start a car.He tried again and again but couldn't get the car moving.Arthur turned and looked inside at the face of a young man who looked worried.Arthur stopped and asked, "It looks like you've got a problem."
"I'm afraid so.I'm in a big hurry and I can't start my car."
"Is there something I can do to help?" Arthur asked.The young man looked at the two suitcases in the back seat and then said, "Thanks.If you're sure it wouldn't be too much trouble,you could help me get these suitcases into a taxi."
"No trouble at all.I'd be glad to help."
The young man got out and took one of the suitcases from the back seat.After placing it on the ground,he turned to get the other one.Just as Arthur picked up the first suitcase and started walking,he heard the loud noise of an alarm.
It was from the bank.There had been a robbery!
Park Avenue had been quiet a moment before.Now the air was filled with the sound of the alarm and the shouts of people running from all directions.Cars stopped and the passengers joined the crowd in front of the bank.People asked each other, "What happened?" But everyone had a different answer.
Arthur,still carrying the suitcase,turned to look at the bank and walked right into the young woman in front of him.
She looked at the suitcase and then at him.Arthur was surprised. "Why is she looking at me like that?" He thought."The suitcase!She thinks I'm the bank thief!"
Arthur looked around at the crowd of people.He became frightened,and without another thought,he started to run.
Paragraph 1:
As he was running,Arthur heard the young man shouting behind, "Stop,stop!"____________________
Paragraph 2:
The taxi stopped in front of the Police Station and Arthur._____________________发布:2024/11/28 12:0:1组卷:3引用:2难度:0.5
