Paragraph1--Cause and effect

This year, 2008, people focus more on Beijing because of the coming Olympic Games. People not concern about the rate of process of all the facilities, but also care about the air quality in Beijing. The air quality in Beijing keeps going down during the past few years. The main cause for the problem is the number of private cars keeps going up. As the number of cars increases, the exhaust gas from the cars increases exponentially. Therefore, this is the main factor of air pollution in Beijing. Since cause is already very obvious, what is the effect then? Because most of the games are outdoor games in Olympics, so the low quality air is bad for all the athletes’ health. Moreover, the audiences will also suffer a lot form the dirty air. Before Beijing was selected to be the host for 2008 Olympics Games, the Beijing government’s slogan is “let’s try our very best to make the 2008 Olympics become a Green Olympics.” Hence, the Beijing government should really try his very best to improve the air quality in Beijing. Let’s step by step to improve the air quality. Let’s hand in hand to hold a green Olympic Games.
