With the development of the Internet, knowledge resources on the Internet are becoming more and more abundant, and online learning is becoming more and more common. When more and more people tend to study online instead of going to school, the following situations may happen. First of all, the optional learning resources of online learning are diverse and efficient. In the future, people's cultural literacy will become higher and higher. One person has multiple professional knowledge, and everyone is a slash youth. Secondly, online learning doesn't have to go out or run among multiple classrooms. In view of this, most people may stay in the room all day, and they won't go out unless necessary, so their daily activities are reduced. Except for those who like fitness, most people will suffer from physical deterioration. In addition, if online learning takes the place of going to school, most people will lack the experience of face-to-face communication, which will easily lead to the increase of people with social fear. Finally, online learning requires the use of electronic devices, which will release radiation. Long-term use of online learning will lead to decreased vision. In the long run, more and more people will need to wear glasses and walk on the road. Everyone is a glasses family. That's my guess.
