Currently ,with the development of science and tenochlogy, our society is changing at a speed which is quite unprecedented.private cars become one of the key words of our time.There is no denying that the numbers of private cars will be increased sharply in twenty years. The first and foremost reason is that people become richer after the open door policy of china in the past twenty years .For example, twenty years ago ,people only could afford the meals and clothing for their everyday life, their never image they had spare money for something didn't essential, such as cars. But now, the qualities of our living from worse to better, each family have their own cars , even more than ones. Inaddition ,when I was young I dreamed one day I could have a car of myself .so cool it is to drive a racing car .It is no surprise us to discover that everyone have such a dream when they were young. That means if they have the ability ,they will achieve their dream. Although , people become richer is the most important determinant, it is not the only explanation for more people buy cars. Another reason also helps to explain this phenomenon. The government spend more money on building highway .This action have improved the traffic condition. So convenient is the trip that people want to have their own cars.
Undoubtly ,people have spare money and traffic condition is improved support a growth in the cars use, but there is a undeniable demerit. The environment will be polluted by the waste gas which come from the cars .However ,the renewable resource of enery will replace the old resource in twenty years ,the problem is saved easily. To sum up, due to the above mentioned reasons, I hold the point of view that the use of cars can not reduce in twenty years.
