| Li Hua: Surfing the Internet is very exciting. We can do lots of things, such as playing games listening to music, chatting with our friends and so on. I really enjoy it. Wang Gang: I like surfing the Internet,too. Because I can learn a lot from it. I can get the latest news all over the world. I also can find the information I need so that I can spend less time on my homework. Zhang Jie: It's hard to say. I agree that the Internet is helpful to our study. But it's not right to spend too much time on the games. And some information on the Internet is bad for our mind. What's more, surfing too much does harm to our eyes. In a word, we should use the Internet in a right way.
