First, car makers wanted to take the human out of driving. Now, motorcycle manufacturers (制造商)want to do the same. But just as the driverless car movement has faced skepticism, it's not entirely clear that the world needs autonomous motorcycles.

What would a self-driving motorcycle do? It would be designed to let the rider sit back and relax while the machine drives by itself. Manufacturers have actually been creating and improving prototypes (原型)of self-driving motorcycles for years, and they're only just now beginning to share them with the public. For instance, AB Dynamics and AutoRD released the Autonomous BMW Cl. It comes with autonomous software, GPS, and re-balancing technology.

Yamaha's Motoroid is a model that uses artificial intelligence and self-balancing technology. The Motoroid sounds very futuristic, but it can't drive on its own. It needs a rider to make turns. Another example of an autonomous-light motorcycle is Honda's Riding Assist-e, which can change the center of gravity autonomously. However, like the Motoroid, it's not completely self-riding and isn't ready for a highway on its own.

Safety concerns for autonomous motorcycles are similar to those that trouble self-driving cars Firstly, the autonomous system may make a mistake and endanger the rider. Self-driving cars have an unfortunate record of running red lights and causing accidents. Professor Adam says, "So one can be forgiven for worrying about the safety of a two-wheeled speed machine with no one behind the handlebars. '' Secondly, there's the question of responsibility: Who is at fault if a self-driving bike crashes into another car? More importantly, it's not easy to satisfy the official regulations before autonomous motorcycles ride on the road. And to develop the industry will cost billions of dollars.

But there's the biggest problem with all of these motorcycles. One of the joys of driving motorcycles is the driving. It seems unlikely that a rider, like a high-speed motorcycle collector who loves the thrill of turning around corners, will give up the experience of the ride.

The prototypes for self-riding motorcycles are here, and manufacturers are busy putting them to the test, but it might be a while before we see them on the open road.

The founder of electric supercar maker Rimac has said it won’t make sense for people to own or drive their own cars in the coming decades.

According to Rimac, most people will no longer own or operate their own cars in the future.Instead, vehicles will be shared, self—driving and electric.These changes are already starting. “There will be people who still want to own their cars and drive their cars and I am happy for that because that is our business, ”Rimac said. “Long term, I think 20 years down the road, it will be totally changed and people will not own or drive their cars anymore.”Rimac’s most recent car.the C—Two, comes off the production line next year.

Rimac is well aware the industry is changing quickly due to the rise of self-driving vehicles and electric batteries, and says in the next 20 years driving as we know it may exist mainly as a hobby. “I really believe that humanity goes for things that make sense.”he told Newsweek. “If you look at 1.3 million people dying every year on the roads, if you look at the impact it has on economies based on traffic jams and time lost, it’s so much of a negative impact to society that I think such a huge benefit can be gained if people stop driving.”

“Let’s look into the future.You are standing in front of the choice of either investing a huge amount of your money in buying a hunk of metal and plastic for 30, 40, 50 thousand dollars, or you have the convenient option of paying as you go, the car picks you up in a few minutes, it’s a nice environment and you spend a few dollars per day on your transport.”

“When you take the driver out of the car, transport can be much cheaper and you can use the time to do other things, instead of sitting behind a steering(转向)wheel and not doing anything else.So I think the choice for the vast majority of people will be the obvious one.”

1.What can we learn from paragraph 2?

A.The majority of people will purchase cars.

B.Huge changes will take place in car industry.

C.Driving cars will enjoy more popularity.

D.The car business is gradually disappearing.

Many youths want to lean how to drive cars. This year one sixth of undergraduates in Beijing have registered at driving school. The students, mostly from majors such as business management or imitational trade, will finish their driving courses within 20 days or so.

Training costs have dropped to 4, 500 yuan for students, according to the Haidian Driving School in Beijing. The price is not really low, but students will accept it, seeing it as an investment (投资) in their future. Familiarity with the operation of computers and fluent English are the basic skills graduating students need to find a job. But a driver s permit has become another factor (因素).

“In the job market, owning a driver’s permit sometimes strengthens a graduating student’s competitiveness for a good position,” says Li Hua, an undergraduate at the China University of Political Science and law.

Cars will become a necessary part of many people’s lives in the coming years, and it is difficult to get a permit out of campus because of the pressures on working people’s time. “Having a full-time job after graduation offers limited time to learn to drive. We senior students have plenty of spare time, plenty of oppurtunity to learn,” says another undergraduate at the university.

Wu Dong, an official at the driving school, said undergraduates were very able and serious, and could grasp in an hour what ordinary people took four hours to learn. In this driving school, middle-aged people, young women and college students are the main customers.

From March 1, 2018, to get a driver’s permit, a beginner is now required to have at least 86 hours’ practice before the final road test.

1.Why do the undergraduates learn to drive?

A. They are the students from special subject or course.

B. They like to drive cars very much.

C. They want y become full time drivers after graduation.

D. They need this skill to find a good job in the future.

2.What is Wu Dong’s opinion of students learning to drive?

A. It would make the life more interesting.

B. Youths would have an advantage in learning to drive.

C. It is a waste of money and time to learn to drive.

D. It would be better to learn it at college than at work.

3.To get the permit, the student ________.

A. requires some time to practice before the final road test

B. must pay more money before the final road test

C. must practice more to learn to drive when having a job

D. requires to learn some more other subjects to drive

Four out of the 48 self-driving cars on public roads in California have been involved in accidents in the last eight months, according to the state's Department of Motor Vehicles.

The agency began issuing permits for the testing of self-driving vehicles in September 2014.

Three of the four cars belonged to Google, the fourth to parts supplier Delphi.

Both firms denied their vehicles had been at fault.

Under Californian law, details of car accidents remain secret.

However, Google said its driverless cars had never been the cause of an accident and that the majority of "minor fender-benders(擦撞)" had been in the form of rear-end(后尾) collisions from other drivers.

"Safety is our highest priority. Since the start of our programme six years ago, we've driven nearly a million miles automatically, on both freeways and city streets, without causing a single accident," said a spokesperson.

Delphi told the BBC its vehicle was hit while still at a crossroads and was in human driving mode at the time.

"A police report indicates the fault of the accident is with the second vehicle, not Delphi. No-one was hurt in the incident," said a spokesperson.

An unknown source told the Associated Press that two of the accidents occurred while the vehicles were occupied by human drivers, and all four vehicles were going very slowly at the time of the collisions.

Chris Urmson, director of Google's self-driving car programme, wrote in a blog post that there have been 11 accidents involving Google cars since the project began six years ago but not one has been caused by one of its vehicles.

"Rear-end crashes are the most frequent accidents in America, and often there's little the driver in front can do to avoid getting hit," he said.

1.What is the passage mainly about?

A. Self-driving car accidents.　　 B. Motor vehicle problems.

C. Self-driving vehicle problems.　　 D. Traffic accidents in California.

2.We can learn from the passage that the self-driving cars ______.

A. caused the accidents when driven by human drivers

B. hit other cars and caused the accidents

C. were responsible for the accidents

D. were knocked into from behind

3.The passage intends to tell us that the self-driving cars ______.

A. are just road killers　　 B. need to be improved

C. are in good quality　　 D. shouldn’t be produced
