　　BBS and middle school students

　　Nowadays, with the population of computers among middle school students, BBS has become an indispensable part of their life.

　　BBS is the abbreviation of bulletin board system. Its main function is to enable people to communicate on “boards”. Each authorized person can post articles on boards, or just reply other people’s posts. Students can discuss all kinds of topics on it, serious or easy. It can keep the students well-informed of the current events happening both in the world and on campus. What’s more, they can not only discuss and exchange opinions through BBS, but also make friends, sell and buy second-hand products. It serves as a splendid information center for middle school students.

　　However, just as the saying goes: No garden without weeds. Not to mention the garden of BBS. It is not immune to some illegal and nasty information. For example, you always can see advertisements about looking for a substitute examinee on BBS. Besides, some students have spent so much time on posting on BBS that they even forgot eating and sleeping, which results in many adverse consequences.

　　Anyhow, BBS indeed provides fertile soil for critical thinking, and encourages free speech of middle school students. Therefore, we should work together to make BBS a better place for communication.
