Social Network Sites
In recent years, social network sites like Renren and Kaixin have rapidly gained popularity among all kinds of people. Many people spend a lot of time on those sites chatting, making friends and playing games. Those sites have become a part of their life.
The public hold different views on this phenomenon. Some are in favor of those sites for they provide many opportunities to know other people and to know what's happening in the world. Besides, they're very convenient to access. One can use a computer or cell phone to log on at home, in a restaurant, or even in the subway. But some people don't approve of the social network sites. They say that people are wasting too much time on the sites. Some even get addicted to them and abandon their real life. After all, they don't live in the virtual world.
In my opinion, the social network sites can be very helpful when we want to keep in touch with friends, but we must remember that the real world is the most important in our life.
