参考答案：

Look at the sign of the Chinese Young Volunteers. It is made up of a passionate heart that is full of love and enthusiasm, a hand that is always ready to offer help, and a pigeon that symbolizes the desire for a peaceful world. Volunteer services are indispensable in a society, especially at times of disasters or special events.

The majority of the Chinese young volunteers are students. Busy as they are with their courses, they have good reasons to participate in volunteer projects. For one thing, involving in activities other than the day-to-day school work makes a difference in their life. Secondly, the opportunity to get acquaintance with various people and learn skills of problem-solving may help develop their communication and troubleshooting abilities. All this is not likely to be learned in the classroom. Most important of all, the joy of helping others and giving something back to the society brings about real happiness.

It is a good idea to participate in volunteer work regularly and do our bit wherever we can. It adds meaning to our life. In addition, by taking us further out of our comfort zone, it often offers far greater rewards.
