题目：Many young people spend a lot of time on the internet without any parental supervision or control. What are some problems unrestricted use of the internet?

Human beings can’t live without the internet that people use it through electronic devices, this why electronic devices are considered to be human mechanical organs. But when people get internet addiction and lose control, it will cause a lot of problems: 1.Too much concentration hurts your eyes.  2.Using the internet for too long will affect your learning rate. 3.You may ignore your parents’ feelings. Young people should learn to control the internet,not be control by it .As far as I am concerned, it need time to practice how to control the internet. Now the government has put in place corresponding policy, that is minors are prohibited from using the internet for a little more than two hours. Parents should also try to play with the phone as little as possible to set an example for their children.
