limiting tbe buying of cars or not?

beijing has placed strict restriction on the number of newly purchased car in the city and the policy bas sparked heated discussion. some people support the policy, saying it，s a powerful method to cope with the severe traffic congestion in the capital. with cars increasing drastically in the past few years, severe traffic jams occur not only in rush hours but at any time of the day now.

others, however, aie strongly against the limitations. they argue that the great number of official cars，which are frequently used, is a big factor causing traffic congestion. but the policy mainly aims at private cars and has no dear restrictions on the use of official cars. besides, car purchase limitation would hinder the development of china's automobile industry，and more people would lose their jobs as a result.

personally, i think the restriction of buying and use of cars, official cars incladed, is inevitable and just a matter of time for beijing. if the number of cars is not limited, there will be a huge disaster for the environment, road resources, the travel demands of normal people and the improvement of living standards.

how to enhance our sense of happiness?

1. 人们对于如何提升幸福感有不同的看法

2. 幸福感的提升不仅包括物质层面，也包括……

参考范文： how to enhance our sense of happiness?

along with the improvement of living standards, people are no longer content with being fed and clothed adequately. they are more concerned about how to enhance their sense of happiness.

to a large extent, happiness depends on individuals’ understanding about it. for some people, happiness relies on material basis, without which they can’t live comfortably and decently. for others, they believe that happiness has nothing to do with money. thus to enhance happiness is not equal to improving one’s material living standards. instead, people are supposed to confront their life with right attitude, to be active and grateful in order to have a happy life.

for my part, money does buy happiness, but only up to the point where it enables one to live comfortably. to boost one’s happiness not only needs the material but also the spiritual enrichment. it encompasses living a meaningful life, utilizing your gifts and your time, living with reflection and objective.
