With the development of the internet, many students enjoy surfing the internet in their spare time. On one hand, there're many resources on the internet and it's easy for students to find out what they need. Many websites store much knowledge and open up to students. Some websites also provide students with teaching videos. They're useful and helpful for students' study.
But on the other hand, surfing the internet causes a lot of problems. Some students are crazy about online games. The internet takes up nearly all the students' spare time and they have little time to spend with their parents and friends. They have trouble getting on well with others.
In my opinion, students should use the internet properly. It's better to regard the internet as a good helper in our study. Don't lose yourself in the computer.
