You know how much your telephone has changed over the past 10 years? Your car will change even more than that in the next 10 years. One of the biggest changes is that cars will drive themselves.

"We certainly have the technology for it now." says Andrew Poliak of automotive（机动车辆的）technology supplier QNX ."We expect self-driving cars to be a mainstream（主流）thing between 2020 and 2025."

The American company Google has been working on self-driving cars for years. These cars are already on the roads in the United States and are truly self-driving. Last week, the police ordered one of Google's cars to stop for driving too slowly on a public road. The car was not breaking any law, so no one was punished.

Another American company, Tesla, added an "Autopilot" feature(特点) to its cars last month. With the Autopilot turned on, the vehicle drives itself. The car will speed up, slow down, brake(刹车) and drive by itself. You can take control of driving any time by turning the steering wheel or touching a pedal. The car uses sensors（感应器）to know when driveway changing is safe and whether it should speed up or slow down.

Tesla Autopilot is made for cross-country driving. It keeps you in the driveway and helps you avoid hitting other cars. It does not work well on local roads, for it will not stop at a red light or stop sign.

Reporter Carolyn Nicander Mohr tried the Autopilot feature(特点) of a Tesla earlier this month. She had a hard time trusting the car to do what it should do. She thought about canceling the Autopilot feature many times during her trip. She wanted to take control at every corner in the road and hit the brake when the car in front of her slowed down. However, the car drove perfectly itself.

Other companies like Marcedes-Benz, Audi, BMW, Volvo and Toyota are all working on self-driving cars, too.

1.What do Andrew Poliak's words probably mean? ______

A. It is too difficult for people to make self-driving cars now.

B. Self-driving cars will be first put on the market in 2020.

C. There will be more self-driving cars in use in the near future.

D. Nobody loves to use self-driving cars at the moment.

2.Which of the following is true according to the passage?

A. One of the Google cars was fined for breaking the law last week.

B. The Tesla’s car with Autopilot feature can sense traffic lights in front of it.

C. Tesla Autopilot car worked much better than Reporter Carolyn expected.

D. Tesla Autopilot is made for cross-country driving as well as local-road driving.

3.Which word has the same meaning as “autopilot” ______ .

A. speed up B. self- drive C. slow down D. brake

4.According to the text，how many companies mentioned(提到)are working on self-driving cars?

A. Three B. Five C. Six D. Seven

5.From the passage, we can infer(推断)that ______ .

A. Self-driving cars are popular nowadays.

B. Self-driving would be trusted by anyone.

C. Self-driving cars will be totally safe in the future.

D. Self-driving cars still need improving.
