With the rapid development of the Internet, some students lose themselves in the Internet. In order to keep their children away from the Internet, some parents don't allow them to use mobile phones on weekdays. On weekends and holidays, children are only limited（限制） to an hour a day for the Internet. What＇s your opinion about this？
Some children need to use screens for homework. And many of them need to talk to friends online. It's not fair to students who are careful with their screen time.

I think parents should limit screen time for kids. Too much screen time can lead to tiredness and less social time. People who use smart phones for long are more likely to（更有可能）get into car accidents. Electrical products like computers can also be harmful to kids. If kids aren't careful with the websites they use, someone will get their important information.

A study from a university says screen time might be less harmful to kids than people think. Some parents worry that children online too much won't make friends.But the study reports that screen time can actually improve kids' friendships. In fact,screen time can be educational. I use websites to read and to learn math.

Many students spend too much time on their phones. This hurts their eyes and wastes their time. Surfing the Internet for long can influence kids' learning and social skills. If parents limit screen time, children will be encouraged to spend more time with their family.They might join a sports team in their neighborhood.
