[by:www.Tingvoa.com - VOA英语网] [00:00.00]如果你喜欢voa英语网(www.Tingvoa.com),请介绍给更多的同学哦 [00:00.05]Topic 5: Cars and Air Pollution [00:04.19]Too many cars have caused a lot of serious problems [00:09.13]in our world. [00:10.15]Besides congestion, accidents and fast fuel consumption, [00:15.17]cars are responsible for a good part of air pollution in big cities. [00:20.29]One possible solution is to design [00:24.02]and develop clean cars and clean fuels. [00:27.81]In Shanghai, [00:29.09]some of the public buses begin to run on natural gas, [00:33.50]which does not give off as much carbon dioxide as petrol. [00:37.69]Another solution is to develop [00:40.51]modern public transportation systems [00:43.27]and restrict the use of private cars. [00:46.24]If the price of petrol rises constantly [00:50.13]and the public vehicles are efficient and convenient enough, [00:53.96]most people will not buy private cars. [00:57.86]Thus, the total number of cars in big cities will reduce greatly. [01:03.34]On the whole, the elimination of air pollution [01:07.43]needs the collective efforts from the government, [01:10.61]the public and the environmentalists. 来自:VOA英语网 文章地址: http://www.tingvoa.com/html/20180326/545578.html
