Nowadays more and more families own private cars.Private cars,as the product of modem civilization,have been playing a vital role in people's daily activities.First,private cars are a convenient means of transportation.You can go wherever you like.Secondly,there is no doubt that private cars will have a great impact on the economic growth.The rapid car industry growth will contribute much to keeping the country's economy growing at a higher rate in the near futrue.But every coin has two sides.The development of the private cars will bring about a series of problems.For example,the polluted air given off by cars will do great harm to our health,too many private cars will lead to traffic jams and a great deal of energy will be wasted and so on.So I think we should take advantages of private cars and make them serve us better.Meantime we hope that satisfactory solutions to these negative problems will be found soon.現(xiàn)在,越來越多的家庭擁有私家車.私家車作為現(xiàn)代文明的產(chǎn)物,在人們?nèi)粘Ｉ钪邪缪萘酥匾慕巧?首先,私家車是很方便的交通工具,你可以開車到處跑；其次,毫無疑問私家車對經(jīng),濟(jì)的增長起到很大的作用.在不遠(yuǎn)的將來,快速發(fā)展的汽車工業(yè)在保持國家以較高速度的增長方面將做出很大的貢獻(xiàn).當(dāng)然,任何事物都有其兩面性.快速發(fā)展的私家車會導(dǎo)致一系列問題.例如,汽車排出的廢氣對人體有很大的傷害,太多的私家車會導(dǎo)致交通阻塞,很多能源被浪費(fèi)等.所以我認(rèn)為我們．應(yīng)當(dāng)充分利用私家車的優(yōu)勢,更好地為我們服務(wù).同時,我們也希望不久這些消極的問題將會得到圓滿的解決.
