New Beijing, Great Olympics

The 2008 Olympic Games has been the most cheerful and anticipated(预先的) event throughout Beijing ever since Beijing was rewarded the right to host the 2008 Summer Olympic Games, yet the focus should be shifted from making a promise to carrying out the promise made.

  In my point of view, to bridge the gap between the promise and reality, Beijing still has a long way to go. To begin with, basic-structure construction should be the primary concern. Such basic-structures as communications and transportation system and facilities ought to draw our constant attention. For example, traffic jam has been an age-old headache in Beijing. The scene of long queues of vehicles worming their way inch by inch will surely cause great disorder, and impair the image of the city meanwhile. Next, to add charm to convenience, overall cityplanning is quite necessary. Time permitting, a redesign of city plan and adjustment of architectural style would provide a better environment for cultivating the characteristic, mixing oriental elegance(东方的雅致) with international greatness, will tower aloft(在高处) among surrounding architectures. To achieve such effect, Beijing shall seek opinions from first-rate architects and make an overall plan. Thirdly, quality of the population should be improved. To make an international metropolis, both “hardware” and “software” are important.

  However, Rome was not built in a day. To carry out the promise of “New Beijing, Great Olympics”, deeds speak louder than words.
