Preparing Cities for Robot Cars
The possibility of self-driving robot cars has often seemed like a futurist’s dream, years away from materializing in the real world. Well, the future is apparently now. The California Department of Motor Vehicles began giving permits in April for companies to test truly self-driving cars on public roads. The state also cleared the way for companies to sell or rent out self-driving cars, and for companies to operate driverless taxi services. California, it should be noted, isn’t leading the way here. Companies have been testing their vehicles in cities across the country. It’s hard to predict when driverless cars will be everywhere on our roads. But however long it takes, the technology has the potential to change our transportation systems and our cities, for better or for worse, depending on how the transformation is regulated.
While much of the debate so far has been focused on the safety of driverless cars(and rightfully so), policymakers also should be talking about how self-driving vehicles can help reduce traffic jams, cut emissions(排放) and offer more convenient, affordable mobility options. The arrival of driverless vehicles is a chance to make sure that those vehicles are environmentally friendly and more shared.
Do we want to copy — or even worsen — the traffic of today with driverless cars? Imagine a future where most adults own individual self-driving vehicles. They tolerate long, slow journeys to and from work on packed highways because they can work, entertain themselves or sleep on the ride, which encourages urban spread. They take their driverless car to an appointment and set the empty vehicle to circle the building to avoid paying for parking. Instead of walking a few blocks to pick up a child or the dry cleaning, they send the self-driving minibus. The convenience even leads fewer people to take public transport — an unwelcome side effect researchers have already found in ride-hailing(叫车) services.
A study from the University of California at Davis suggested that replacing petrol-powered private cars worldwide with electric, self-driving and shared systems could reduce carbon emissions from transportation 80% and cut the cost of transportation infrastructure(基础设施) and operations 40% by 2050. Fewer emissions and cheaper travel sound pretty appealing. The first commercially available driverless cars will almost certainly be fielded by ride-hailing services, considering the cost of self-driving technology as well as liability and maintenance issues(责任与维护问题). But driverless car ownership could increase as the prices drop and more people become comfortable with the technology.
Policymakers should start thinking now about how to make sure the appearance of driverless vehicles doesn’t extend the worst aspects of the car-controlled transportation system we have today. The coming technological advancement presents a chance for cities and states to develop transportation systems designed to move more people, and more affordably. The car of the future is coming. We just have to plan for it.
1.According to the author, attention should be paid to how driverless cars can __________.
A. help deal with transportation-related problems
B. provide better services to customers
C. cause damage to our environment
D. make some people lose jobs
2.As for driverless cars, what is the author’s major concern?
A. Safety. B. Side effects.
C. Affordability. D. Management.
3.What does the underlined word ＂fielded＂ in Paragraph 4 probably mean?
A. Employed. B. Replaced.
C. Shared. D. Reduced.
4.What is the author’s attitude to the future of self-driving cars?
A. Doubtful. B. Positive.
C. Disapproving. D. Sympathetic.

The ride-sharing company Uber has removed its self-driving cars from the streets of San Francisco,California. The action came after a dispute between Uber and state officials over whether the vehicles needed special permits to operate.
Uber recently launched testing of its self-driving service in San Francisco.But shortly after the launch, California's Department of Motor Vehicles (DMV) told the company to stop the self-driving vehicles.State officials said the Uber cars needed the same special permit given to about 20 other companies testing self-driving technology in California.Uber argued that its technology does not make vehicles fully autonomous,and so the special permit was not needed.It added that all of Uber's "self-driving" cars have a driver sitting in the passenger seat to take over if needed.
The head of Uber's self-driving technology,Anthony Levandowski,explained the company's position in a blog post.He said the self-driving Uber vehicles do use high-technology tools to assist drivers.But they are not fully autonomous and require a driver to be at the controls at all times..He compared the technology to solar carmaker Tesla's advanced driver assist tools.Telsa's Autopilot system allows its cars to steer in a lane,change lanes,and speed up or slow down based on nearby traffic.The company tells drivers that,when using Autopilot,they should still always be ready to take control of the vehicle.Vehicles equipped with these high-tech driver assist tools do not need a special permit to operate in California.
It's hard to understand why the DMV would seek to require self-driving Ubers to get permits when it accepts that Tesla's autopilot technology does not need them,"Levandowski wrote.San Francisco's mayor,Ed Lee,praised the DMV for stopping Uber's self-driving vehicles.He said he supports self-driving development and testing.But only under conditions that put human bicyclists' and pedestrian safety first."
1.What does the underlined word "dispute" in Paragraph 1 mean?
A. Discussion. B. Disagreement.
C. Fighting. D. Meeting.
2.Why does Uber say that the special permit was not needed?
A. Because Uber's "self driving" cars are fully autonomous.
B. Because there are passenger seats in Uber's "self-driving" cars.
C. Because no drivers are needed in some Uber's "self-driving" cars.
D. Because Uber's "self-driving" cars can be operated by humans when necessary.
3.What can we know from the passage?
A. Uber's self-driving cars need human drivers.
B. Telsa's Autopilot needs special permits too.
C. Uber's self-driving cars are completely autonomous.
D. Telsa's Autopilot system is better than Uber's self-driving technology.
4.What can we infer from Ed Lee's words?
A. He doesn't think DMV is right.
B. Uber's self-driving cars should he supported.
C. Uber's serf-driving cars are not safe enough.
D. One should be careful while walking or cycling in streets.

Twenty-year old Brian, our eldest son, was riding his motorcycle home from work when a drunken driver ran him down. The driver, Ruben Gonzalez, was accused of man-slaughter (过失杀人).

Relief flooded my husband's face and I knew he felt the same. He picked up the phone and dialed the judge's office. "I hope it's not too late, " Charles said.
