14.These days no car show is complete without an electric car,and the 2011North American International Auto Show in Detroit,US,which ran from January 10to 23,was no exception.Among the fully electric vehicles on display were the Ford Focus Electric and the Honda Fit EV.BMW and Volvo also had prominent displays at the show,proving that they can produce practical,yet spacious family-oriented electric cars.
Industry insiders at the show claimed that more efficient batteries,improved performance and greater consumer acceptance could make 2011the"year of electric car".
It's long been clear that electric cars score heavily for convenience.They are,for instance,much easier to maintain than gasoline-powered cars.When the battery runs out,you simply replace it or recharge it,just like you would for a cell phone or a laptop.
This is also a much cheaper method than filling your tank with gasoline.Better yet,electric cars don't emit exhaust fumes.As a result,they don't produce environmentally damaging greenhouse gases.
It appears that improved technology is making electric cars and their maintenance much more user-friendly.So,what are the obstacles which are preventing electric cars from becoming popular and fashionable?
Home charging for electric cars could be extremely convenient for users.However,it is also a potential obstacle.For a start,installing charging stations in owners'homes will be a challenge,particularly for those who have to park several blocks away from their homes.
Also,charging the car's battery still takes quite a long time.It may be some time yet before you can recharge an electric car in the same time as you can refill your gas tank.
Another problem is that many electric vehicles have limited ranges that may only allow for journeys of 50miles (80km) or less between charges.In cases where a driver wishes to charge the car primarily at home (perhaps overnight),this limits their daily driving to the range of their vehicle.
This may be one reason why hybrid cars are now becoming more popular.A hybrid car has more than one energy source,usually a traditional gasoline fuel tank and an electric battery.It's like a more practical version of an electric car:It's greener than a conventional vehicle,with fewer CO2emissions,yet it also doubles as a conventional vehicle.
"I would say that hybrid is a transition to fully electronic,"Road and Track magazine editor Richard Horman told Detroit News during the show."The trend is for lighter,smarter,more economical cars.Of course,electronic vehicles are meant to be that way."
This sounds promising,particularly in light of the fact that the show featured more electric cars from big manufacturers than ever before.
However,it seems that the technology associated with electric cars is not yet able to fully meet people's expectations.Don't expect gasoline-powered cars to disappear from roads just yet.
60.What made electric cars more convenient?A
A.Easier maintenance.
B.High scores on the show.
C.Practicality and large space.
D.Much lower prices.
61.Which of the following could NOT act as a potential obstacle of electric cars?D
A.It is rough work to install charging stations at home.
B.It is time-consuming to charge the batteries.
C.The ranges between charges are limited.
D.There's no need to fill the tank with petrol.
62.In Paragraph 10,the underlined word"hybrid"is probably closest in meaning toC.
A.gasoline B.electric C.combined D.separated
63.The writer's purpose in writing this passage is toB.
A.introduce the 2011Auto Show in US B.get readers informed of electric cars
C.comment on different types of cars D.advertise for electric cars.
