6．Internet is always educational．Many people think children should be allowed to surf the Internet as they wish．In this way，they can look through different subjects on different kinds of websites according to their own interest．But in my opinion，children should always be watched while surfing the internet．Many websites have information and pictures that children should not see．There are many things that children don't understand．All of these may have some bad influence on children's development．Also，it is dangerous to let children use chat rooms by themselves．Many parents tell their children not to talk to strangers on the street，so they should be careful of whom their children talk to on the Internet，too．What's more，sitting in the front of a computer for a long time isn't good for children's eyes，so parents should monitor（监视） the time that children spend on the Internet．
In a word，children should be kept away anything that could be bad for them．I believe that it is necessary for parents to watch their children when they use Internet．
