　　On Volunteer
　　In recent years, the volunteering spirit has spread widely among the public, especially among youngsters. From Olympic Games to urban communities, many people are seen to offer free help.
　　Volunteering is of tremendous benefit to those in need. For example, hundreds of thousands of volunteers played an active role in the recent quake-hit Yushu area: they offered medical and psychological aid to the victims in the relief work. On the other hand, volunteering is beneficial to the volunteers themselves too. Involved in volunteering activities, people are exposed to new circumstancesj and they can learn how to work well in a team and how to improve their interpersonal skills, all of which are critical for their career development.
　　In my view, we should all join in volunteering work as long as we have spare time. That doesn’t necessarily mean that we all volunteer in regions struck by natural disasters. There are many people eise who need our help, i.e. the old or the sick in the near nursing home. Little by EittJe, we are sure to help make the world better.
