参考范文：　　In recent years, there has been a growing popularity of volunteer activities. The volunteer spirit is spreading among college students. They actively take part in various volunteer activities, such as rescue work in earthquakes and service work in the Olympic Games.　　There is no doubt that volunteer activities are of remarkable benefits to both the society and the volunteers themselves. For one thing, college students' active participation in volunteer activities not only helps those in need but also calls on more people to join them, which influences the society in a positive way. For another, when engaging in volunteer activities, college students can gain a lot of social experiences. In this sense, it is volunteer work that enables students to learn the importance of devoting spirit, which contributes to their all- round development.　　As a college student, I think volunteer activities should be greatly advocated. In the process of voluntary activities, we can develop our humanism spirit and cooperative ability which are essential to our growth.
