1.Agree or not agree: the next twenty years from now on, students will not use printed books any more.
　　
　　I don't think so. printed books won't be abandoned in such a short time. I admit that new technology is developing fast. Many advanced electronic products are gradually take the place of traditional tools. Just like in university, teachers like to use multimedia in class for it is quite convenient and efficient. However, for our student, it is not realistic to study completely by electronic products. There are many things need to recorded on books. Books are something meaningful and practical. I should say, in our country, printed books wouldn't be abandoned within 20 years at least for two reasons. Firstly, books are classical container of knowledge. They accompany human to advance. A student without books could be someway ridiculous. Secondly, our country haven't developed so strong to make every student study by computer or other forms of electronic tools. And even after 20 years, the possibility is also very small. I also think it is unnecessary because books are cheap but useful and still meaningful.

　　
　　2.Agree or not agree: working together is better than working alone.
　　
　　I think work together is better than work alone. There are many benefits of working together. Firstly and obviously, working together can collect many useful and excellent ideas especially when we are thinking some complicated problems. After all, each person has his own way of thinking. After getting all ideas together, you will often find that things become much easier. Secondly, working together can avoid mistakes to a great extent. People may make wrong judge when their mood is not stable. In this case, teamwork will do great favor. Your partner could remind you of your mistake and turn the result to a good one. Thirdly, when we work together, we need be patient and not self-centered. You need to listen to others?opinion and learn to get well along with people around you.?opinion and learn to get well along with people around you.
