In the past years, the extraordinary contributions of Chinese volunteers have been seen everywhere, from responding to the May 12 earthquake to other big international events..
(Take the WenChuan Earthquake as an example. After the devastating earthquake hit southwest China's Sichuan Province, more than one million volunteers plunged into relief work within days. They went all out to save the victims, provide psychological counseling and donate money and materials.)可以省略
Besides, volunteering would be beneficial to the volunteers themselves. Getting involved in volunteering, volunteers will be exposed to a new environment, and they can learn how to work well in a team, how to improve their interpersonal skills and organizational skills, all of which are critical for their professional growth.

A sound social volunteer service system with frequent activities and full participation should be established and "Learn from Lei Feng" activities should be held on a regular basis to create a social atmosphere of altruism.
The volunteer service system will also help to build a harmonious environment for our society. As a college student, I sincerely hope that everyone would join the volunteer work.
