题目: Many young people spend a lot of time on the internet without any parental supervision or control. What are some problems caused by unrestricted use of the internet?
There are a variety of issues of using the internet if people use it out of control. First and foremost, overuse of the internet can do great harm to our body. It can not only cause to back strain or muscle strain, but also even lead to obesity. What’s more, they could suffer from eye strain if they spend a number of time sitting in the front of the screen. On the other hand, if students waste most of their time on the internet, they may have a big trouble in study and the grades will decline. What is worse, people who spend more time on the internet may isolate society because they do not know how to communicate with others.
