单选题Oil is a nonrenewable resource, whereas sunshine is limitless. So why not run cars on solar power? Because a car powered by solar collecting panels would be fine on a sunny day, but as soon as the sun went behind a cloud, the car would no longer functi
题目
Solar power is cleaner than fossil fuels, and it involves less geopolitical risk.
In most of the northern hemisphere, it can be expected that more than 150 days a year will be cloudy.
No system exists for storing solar energy for a car’s use when the car is not in direct sunlight.
No one has yet introduced a commercially viable process for mass-producing solar cells that convert more than 10 percent of incoming sunlight into usable energy.
Consumers accustomed to the rapid acceleration of gasoline-powered cars will not accept the weak acceleration of solar-powered cars.

Pushing Drunk Boss's Car Home
Ten workers in China pushed their boss's car three miles home after' an office party because they were all too drunk to drive. The group was enjoying a meal at a restaurant in downtown Changchun, Jilin Province (northeast China). When the party was over, Boss Zhang Fei found that he was too drunk to drive. Then suddenly they realized nobody had stayed sober enough to drive his car.
Drink-driving was listed as a dangerous offence in China in 2014, esp. when the driver is drunk. Those who break the law will have their driving license revoked, face a heavy fine and may be put in jail. Zhang did not want to leave his car downtown and it was too late to call out another driver to drive the car for him. Someone then suggested they push the car home, and said that the exercise would do them all good. Thus, all ten quickly agreed and set off with Zhang at the wheel. All ten workers pushed their boss's car home through the city streets, laughing and singing during the 45-minute journey. Passers-by were shocked to see the group.
Traffic officers said that as long as the car's engine was not running, it would not be classed as drink-driving under the law. However, it is still very dangerous for so many people to push the car along the road, as it may cause traffic accidents.
21. workers in China pushed their boss's car home in() minutes.
A. 45,10
B. 3, 8
C. 10, 45

A. not have their driving license revoked
B. not face a heavy fine

California Gives Green Light to Space Solar Power
Energy beamed down from space is one step closer to reality,now that California has given the green
light to an agreement that would see the Pacific Gas and Electric Company buy 200 megawatts（兆瓦）of power
beamed down from solar-power satellites beginning in 2016.But some major challenges will have to be
overcome if the technology is to be used widely.
A start-up company called Solaren is designing the satellites,which it says will use radio waves to beam
energy down to a receiving station on Earth.
The attraction of collecting solar power in space is the almost uninterrupted sunshine available in geo-
synchronous（与地球同步的）orbit. Earth-based solar cells , by contrast , can only collect sun light during day-
time and when skies are clear.
But space-based solar power must grapple（努力克服）with the high cost per kilogram of launching things in-
to space,says Richard Schwartz of Purdue University in West Lafayette,Indiana."if you're talking about it being
economically viable for power of the Earth,it's a tough go,"he says.
Cal Boerman,Solaren's director of energy services,says the company designed its satellites with a view
to keeping launch costs down."We knew we had to come up with a different,revolutionary design,"he says.
A patent the company has won describes ways to reduce the system's weight,including using inflatable mir-
rors to focus sunlight on solar cells,so a smaller number can collect the same amount of energy.
But using mirrors introduces other challenges,including keeping the solar cells from overheating,says
Schwartz."You have to take care of heat dissipation（散发）because you're now concentrating a lot of energy
in one place,"he says.According to the company's patent,Solaren's solar cells will be connected to radia-
tors to help keep them cool.
Though Boerman says the company believes it can make space-based solar power work,it is not expec-
ting to crowd out other forms of renewable energy.Laws in California and other states require increasing use
of renewable energy in coming years,he points out."To meet those needs,we're going to need all types of
renewable energy sources,"he says.
A:Right
B:Wrong
C:Not mentioned
