问题    电池技术的快速发展对电动汽车更有利。瑞银(UBS)估计,到明年,拥有一辆电动汽车的总成本将与燃油汽车持平——虽然电动车制造商仍然会亏钱。瑞银乐观地预测,到2025年,电动汽车将占全球汽车销量的14%。其他机构的预测更加谨慎,但也都匆忙上调了预期,因为电池成本降低、性能提升——每千瓦时的成本已经从2010年的1000美元降至今天的130至200美元.

选项

答案 Rapid gains in battery technology favor electric motors. UBS, a bank, reckons the total cost of ownership of an electric car will reach parity with a petrol one next year—albeit at a loss to its manufacturer. It optimistically predicts electric vehicles will make up 14% of global car sales by 2025. Others have more modest forecasts, but are hurriedly revising them upwards as batteries get cheaper and better—the cost per kilowatt-hour has fallen from $1,000 in 2010 to $130-200 today.
