With the development of the modern technology，private car is no longer a luxurious thing for ordinary people，more and more people drive to work instead of going by bus. The popularization of private car has many advantages.First， it is very convenient and time-saving ，you can drive your own car to the workplace instead of waiting for the crowded bus and afraid of being late for working.Second，it can also improve the traffic structure，and help to mitigate the stress of the traffic.Third， the popularization of private car can help to promote the car industry and any other interrelated industries. I believe that in the future the private car will become the most important vehicle and we cannt live without it.

随着现代科技的发展，私人汽车对于普通人来说不再是一件奢侈的事情，越来越多的人开车去上班而不是乘公共汽车。私人汽车的普及有很多优点。首先，它是非常方便和节省时间，你可以驾驶自己的汽车去工作而不是等着拥挤的公共汽车和上班迟到。第二，它也能改善交通结构，有助于缓解交通压力。第三，私人汽车的普及可以帮助促进汽车产业和其他相关产业。我相信在未来的私家车将成为最重要的交通工具，我们不能没有它。
