1. Most Hong Kong teenagers prefer to use their free time to enjoy their hobbies, such as playing computer games, watching televisions, reading books and listening songs.
2. But I think they can also do other things in their free time.
3. For instance, they can participate in volunteer activities.
4. These activities are meaningful and valuable job since you can help lots of difficult people.
5. Moreover, students can broaden their horizons and contribute to our society very much.
6. We know that most people are not happy all time, but we can try our best to help them and cheer up with them.
7. Someone said that Hong Kong are full of selfish people, they do not willing to help other people.
8. It is true that our society is much more materialist nowadays.
9. But I believe that not all of us want to be materialistic.

11. So I strongly suggest every student to take part in volunteer works.
