THE OPINION ABOUT THE CONSTRUCTION OF METRO The construction of metros in metropolis has become a symbol of modernization. As a result, many local governments trend to raise fund and recruit professionals to construct metro. In my city Haerbin, the first line metro has been completed for several years. With the utilization of metro, the citizens in Haerbin have experienced the comfort and convenience that the metro brings. I consider that the metro as a typical moderate transport is very suitable for fast-paced city lifestyle. The metro or subway which run underground has many advantages. First of all, because of its run characteristic, metros ’rails are built underground, it can save aboveground space which is very valuable and increasingly rare in metropolis. Moreover, the metros’ running routes don’t crossover or overlap with other transportation systems, so they are not interfered by other transportations, so as to save passengers’ traffic time. That is also the reason that partly result in the high speed of metro. In addition, the metro is an environment kind transportation. It doesn’t make loud noise as other transportation, for example cars and motorbikes. The metro consume electric power while cars utilize natural gas or fossil oil as energy. In comparison with cars, The advantage that metros don’t exhaust emission is also favored by many environmentalists. In total, the metro as the public transportation is featured for its high-speed and non-pollution. The construction of metros is beneficial for the city that aims at long-term development. It is believed that metros can play a critical role in the urban construction and environment career. 本文来源：https://www.wddqw.com/doc/97fdf9f0a2161479161128a3.html
