这篇雅思写作7分范文的主要内容是讨论了私家车和公共交通之间的关系，究竟在这两个大方面中哪一个比较重要，究竟应该重视哪一个的发展呢?很多人都会说是公共交通，但是该如何做才行呢?

　　As traffic problems become more and more serious in many cities of developed and developing countries, their governments have to try hard and loads of money and energy have been spent to deal with them.

　　Firstly, it is not ficient for the commuters to use their private cars to and back from their workplaces. Occasionally we can see they have to sit on the wheels wasting time and fuel in a heavy traffic jam. At the same time, through burning the fossil fuels, green house gas CO2, CO1, acid rain gas SO2, fumes and dusts are being released into the atmosphere, all of which heavily overload the environment. Thirdly, with the increase of private cars, the road traffic accidents are also rise dramatically. For example, in a city with 5000 cars, there will be at least 250 accidents happening everyday, which also burden the public healthy services.

　　On the contrary, expected public traffic may be an ideal solution to these problems. For example city buses and railways are widely used or being constructed by many cities. People can take buses easily, which can be found every 10 minutes or less in the peak time. Actually, Nottingham Transport Company is building its own light railway in the city, which is announced by the speak man of the company, “It will be completed in the next year, the tickets will be very competitive and at the same time the travel will be very safe and comfortable.”

　　On the other hand, public traffic had its own disadvantages. Usually it cannot provide door-to-door service. It is inconvenient to go shopping by public vehicles. Sometimes you must wait a long time for the train. And quite a lot of people prer to enjoy driving.

　　In conclusion, developing the public traffic is a usul approach to deal with these difficulties. One possible way, if not the best, is to taxi private cars heavily and use these revenues to provide citizens cheaper public traffic services.
