The internet can change our lives for the better. But we should know how to use the Internet correctly.
First, we should use the internet to study. We can find some good information about Chinese, English and math. It can help us a lot with our study. Second, when we chat online, we shouldn’t believe in others easily. It’s dangerous. Third, we shouldn’t spend much time on the Internet. We must finish our homework before playing games. Some games can make us relax, but we mustn’t spend too much time on it.
If we follow the suggestions above, the Internet must help us a lot.
