     Internet is 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 childern 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 childen spend on the internet .

     In a word ,children should be kept away anything that could be bad for them . I strongly believe  that

it is necessary for paents to watch their children when they use internet .
