How to Solve the Problem of Heavy Traffic?
       Nowadays, people in many big cities are complaining about the heavy traffic. It has seriously influenced people's daily life and economic development. To solve the problem, some pieces of advice are put forward. Some people suggest that more streets and roads should be built. In this way,
the traffic density can be redncedi hence speeding up the flow of buses and cars.But the new roads and streets will be filled with many cars and buses soon.
     Some people advise to limit the number of bikes and cars. This can decrease the traffic flow. But on the other haad, this will affect the consumption and make buses more crowded.
     In my opinion, the number of private cars should be put under control. And at the same time, buses should have their own special routes which cannot be used by other vehicles.  Besides, underground train and city train should be developed quickly. ( 151 words)

    怎样解决交通拥挤问题
    现今，许多大城市的人们都在抱怨交通拥堵。它已经严重地影响了人们的日常生活和经济发展。为了解决这个问题，人们提出了一些建议。
    有人建议修建更多的道路。通过这种方法，可以减小交通密度，因此公共汽车与小汽车的速度就可以提上来。但是不久，新的道路又将被更多的公共汽车与小汽车所塞满。
    有人建议限制自行车和汽车的数量，这可以减少交通的流量。但是另一方面，这会影响消费并使公共汽车更加拥挤。
    我认为，应该控制私家车的数量。同时，公共汽车应该有自己的线路，这些线路不能被其它交通工具所占用。此外，应快速发展地铁和城市铁路。
