Some people say yes. The Internet helps make many friends. Chatting on line, students can more freely express their feelings and opinions, and even get help with their foreign language studies.Sample Others, however, think students should not. They say making friends on line is a waste of time, which should be spent more meaningfully on study. Besides, some students get cheated on line.
It is my opinion that students should place their study, health and safety before other things. As for friendship, we can readily find it in our classmates and other people around us. A debateOnline study

Newspapers and websites are two major new media in the world today, both of which can provide us with lots of news and information. But they’re different in some ways.
Newspapers enjoy a longer history and often come out daily with more reliable news and information. They can beSample carried and read almost anywhere you like. So many people like reading them. But they can only contain texts and photos.
On the other hand, websites are quite new and popular, especially among young people. Websites have not only texts with pictures but also audios and videos, which makes stories more interesting. Sample What’s more, they are updated from time to time. So the latest news is always seen on websites instead of in newspapers. But it is not quite convenient for people without a computer connected with the Internet to get information from websites.Read the whole text and fill in the form below.1-56-10advantagesdisadvantagesCareful-reading of Part 1123Statement Supporting factsConclusionPara. _____Para. 5 ___________Para. ___The Internet has _______ effects on our lives.1.
