交通安全：
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 cann't live without it.
