Science is always advancing over time. A self-driving car from the Google may be coming to a street near you. However, you won’t be able to buy it now. “We’re working to build the world’s most experienced driver,” Kraft, director of the project, said. “Everything that we learn in one of our cars gets passed to all of our cars. But you may need to get over the idea of traditional car ownership along the way.”
Google’s software has already driven 5 million miles in U.S. cities, including an “early rider” test in Phoenix last April. Since then Google has grown confident enough to remove the “auxiliary wheel”: a human “safety driver”. Powering the vehicle’s self-driving functions is a series of cameras, radars and sensors on the car’s roof, which detect everything nearby from other vehicles and passers-by to cyclists.
Kraft stressed that Google’s cars aren’t connected—they don’t need a 5G wireless link to go anywhere. “The car has everything it needs to drive on the car itself.” He said, “There are no signals coming from outer space or something telling it to turn right.” The resulting ride may not be too exciting but safe. Kraft added. “We can see three football fields down the road, we would come to a stop before we ran into these crowds.”
Google’s system has a major advantage over the semi-autonomous（半自主的）systems of Tesla and Cadillac, both of which need continued human attention. Kraft said Google plans to have service in every major city by 2028 with thousands of cars driving themselves.
1.What does the underlined words “auxiliary wheels” in Paragraph 2 refer to?
A. A car that is very old.
B. A driver who has been trained well.
C. A part of a car used to sound the alarm.
D. A condition where a driver doesn’t know his role.
2.Why is Google’s car thought to be safe in the text?
A. Because it can get away from danger easily.
B. Because it is equipped with 5G wireless link.
C. Because it can stop before the crowds occasionally.
D. Because it can keep a safe distance from everything nearby.
3.What can we learn from the text?
A. Google’s software has not been tested.
B. Google’s cars have not been put into the market.
C. Driving the Google’s car may not be too exciting.
D. Google’s cars still need driver’s attention all the way.

高二英语阅读理解中等难度题查看答案及解析
From self-driving cars to carebots (care+robots) for elderly people, rapid development in technology has long represented a possible threat to many jobs normally performed by people. But experts now believe that almost 50 percent of occupations existing today will be completely unnecessary by 2025 as artificial intelligence continues to change businesses.
“The next fifteen years will see a revolution in how we work, and a revolution will necessarily take place in how we plan and think about workplaces,” said Peter Andrew, Director of Workplace Strategy for CBRE Asia Pacific.
A growing number of jobs in the future will require creative intelligence, social skills and the ability to use artificial intelligence.
The report is based on interviews with 200 experts, business leaders and young people from Asia Pacific, Europe and North America. It shows that in the US technology already destroys more jobs than it creates.
But the report states: “Losing occupations does not necessarily mean losing jobs — just changing what people do.” Growth in new jobs could occur as much, according to the research.
“The growth of 20 to 40 person companies that have the speed and technological know-how will directly challenge big companies,” it states.
A 2014 report by Pew Research found 52 percent of experts in artificial intelligence and robotics were optimistic about the future and believed there would still be enough jobs in the next few years. The optimists pictured “a future in which robots do not take the place of more jobs than they create,” according to Aaron Smith, the report's co-author.
“Technology will continue to affect jobs, but more jobs seem likely to be created. Although there have always been unemployed people, when we reached a few billion people there were billions of jobs. There is no shortage of things that need to be done and that will not change,” Microsoft's Jonathan Grudin told researchers.
1.According to the report, _____.
A. people won't necessarily lose jobs
B. big companies will face fewer challenges
C. small companies will win against big companies
D. most people will become interested in technology
2.We can infer from the text that in the future _____.
A. people will face many difficulties
B. people will take up more creative jobs
C. artificial intelligence will threaten people's lives
D. most jobs will be done in traditional workplaces
3.What is the attitude of most experts in artificial intelligence and robotics to the future?
A. Mixed. B. Worried. C. Hopeful. D. Doubtful.
4.Jonathan Grudin's words in the last paragraph suggest that _____.
A. there will be enough jobs for people
B. things will change a lot in a few years
C. many people will become unemployed
D. technology will totally change future jobs

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.
