【正确答案】Flea Markets on Campus In recent years, flea markets are on the rise on campus, which are welcomed by many students. However, many people who are not the students also join in the sales, making it similar to the markets outside the campus. This phenomenon has aroused heated discussions. Flea markets play a significant role in making best use of secondhand goods, as what you don't need may be urgently in demand in the eyes of others. What's more, by providing different goods for students to share, flea markets can enhance the friendship among them, and accordingly promote the harmony of the campus. However, some people argue that flea markets can lead to confusion with so many people pouring into the campus. In addition, the quality of goods cannot be guaranteed. As far as I'm concerned, we should take into account the significant role that flea markets play in making full use of goods as well as boosting the harmony of the campus. Despite the drawbacks of flea markets, they are beneficial to the majority of the students.
