　　范文：

　　Based on a recent survey on the Internet, a majority of individuals admit that aging society will bring a variety of problems to their life. Along with the trend of longevity, it has become a trend for people to debate whether it is wise to postpone retirement age.

　　Some people favor postponing the retirement age. In their eyes, it is this policy that enables the aging society to build up enough work-force. As a matter of fact, people in mounting numbers have come to realize this problem in an aging society. Even so, others hold a different view that postponing retirement age carries some risks. This policy can bring old people stress, but cannot arouse their enthusiasm for work, and cannot help them to enjoy their retirement pension.

　　I am convinced that we should balance old people’ interest and this aging society. Thus, if those seniors have enthusiasm for work, we should educate, advocate and encourage them to work and perform their tasks. If we try our utmost to do so, the future of old people’ life will be promising, hopeful and rosy.
