2、137答案与解析 1 【正确答案】 Along with the rapid development of urban traffic, certain problems have arisen, one of which is the traffic jam. It has become common to see passengers and drivers having to wait in long lines of buses and cars during the rush hours. From my own perspective, there are several reas
3、ons for this problem. First, the number of vehicles is increasing much more rapidly than the building of roads. In big metropolitan cities, as the number of traffic vehicles is soaring up recently, the development of road system seems rather slow relatively. No sooner has a new road been completed a

6、. In view of the seriousness of this problem, effective measures must be taken before things get worse.

From what I mentioned above, I believe that it is the development of science and technology that leads to the pollution of environment and shortage of energy.
