3、通用汽車公司的一款實(shí)驗(yàn)型電力汽車的名稱Part III Text AnalysisThe American auto industry has been looking for ways to rescue its sagging bottom line. Better design and better quality are contributing to the beginning of a turnaround, but long-term success is going to mean major changes for the entire industry. Ensuring

4、that success involves planning for an entirely new type of automobile, one powered by electricity. The electric car is still some distance down the road. (topic presenting)Part III Text AnalysisIts rush hour in Detroit, and the interstate freeway, 1-94, is jammed with cars heading for home after ano

The main problem is with the batteries. They are heavy, and the distance a vehicle can travel between overnight charging is limited. Pa

11、rt III Text AnalysisThe biggest limitation of the battery that we have now is the amount of energy that it can store. The battery weighs 870 pounds. It can only store the energy equivalent of about one-and-a-half gallons of gasoline.In addition to the U. S.-based car companies, automakers around the world are working on electric-vehicle research. All are searching for the technology which will lead to a better electric-car battery.
