Should students make the friends online? Some people say yes. The Internet helps make many friends. Chatted online, students can express their feelings and opinions more free, and even get help with their foreign language studies.
Others, however, think students should not. They say make friends online is waste of time, which should be spending more meaningfully on study. Moreover, some students get cheat when they try to meet the friend they made online.
It is my opinion which students should place their study, health and safe before other things. As for friendship, we can readily find them in our classmates and other people around us.
