IV. Listen to the passage and fill in the blanks.

  As the Internet becomes more and more popular, more and more school children are developing IAD. There are about 8 million school children in China with IAD. IAD causes many terrible problems. It’s bad for their development. Some children won’t go to school. Some aren’t friendly to their family or friends. If you use the Internet more than 6 hours every day, it’s typical IAD. School children waste lots of time on the Internet so that they can’t study well. How can we solve this problem? In my opinion, teachers and parents must communicate often. They should show more care for their children.
