Multimedia learning:
  . Advantages: more vivid teaching materials;
  . disadvantages: too many distractions with too many pictures and videos in multimedia classrooms.
Studying online:
  . advantages: being able to choose when and what you want to learn; easy access to the wide range of online information.
  . disadvantages: making it easier for students to copy answers from the Internet; lack of face-to-face communication between the teacher and students; the possibility for students to develop Internet addiction.
2. . I prefer the multimedia way of learning. A multimedia classroom is vivid with teaching materials presented in different ways: slides, pictures, and even movies. Compared with a traditional classroom, a multimedia classroom is more interesting.
  . To be frank, I prefer to study online. In this way I can manage my own time. I can have my own priorities and do things at my own pace. It is simply what I want.
3. . Yes. The Internet is indispensable in teaching and learning nowadays. It is hard to imagine what it would be like without the Internet. We would have no easy or quick way to learn about the latest development of teaching and learning. We would miss the many interesting online courses; we couldn’t communicate effectively with teachers after class. We just can’t afford to lose the Internet.
  . No. teaching and learning had been carried out long before the Internet came into being. And people did just as well without the Internet or the computer. It is true that the Internet makes teaching and learning more convenient and more efficient, but it is by no means indispensable. I’m sure we can still teach or learn without the Internet.

1 .Yes, I think so. Internet access is a must on campus. We students need the Internet to do research for our study,  to obtain information to broaden our knowledge of the world, to communicate with family and friends, and to enrich our lives in our spare time.
. No, I don’t think so. There are many potential disadvantages if Internet access is so easily accessible on campus. Some students may waste too much time I playing online games or chatting online, be tempted to visit “unhealthy” websites, or even become Internet-addicted and neglect their study.
2 .It sounds like an awful idea to me. Obtaining knowledge is only part of learning.
