含自身经历，对绿色出行的建议，80词左右
Traffic congestion has long been a problem of great concern and complaint in big cities. It has caused a lot of inconvenience to people's life and work. The first cause is the great increase in the number of private cars. Cars take up more space but they carry fewer people. Some private car drivers, ignoring traffic regulations, drive only for the sake of their own convenience, blocking the way of other public transportation vehicles. The second cause is the slow and inefficient construction and improvement of the roads and streets. With a large population and numbers of automobiles increasing, some roads still remain unimproved, which will surely lead to problems. Let all of us act now to solve it.长期来交通拥塞一直是大城市最关心和抱怨的问题.已造成人们生活和工作的很大不便.首要原因是私家车数量的大量增加.小汽车占用了更多空间,但他们却携带很少的人.一些私家车司机无视交通规则,开车时只图自己的方便,挡住了其他公共交通工具的道路.其次是缓慢而低效的建设及对道路和街区的完善.随着人口越来越多和汽车数量的成倍增长,而道路依旧保持原样,无疑会导致问题的产生.让我们所有的人现在就采取行动来解决它.
