We can find some useful information on it or know something happening at home or abroad. We can also have a break or chat with our friends on it. But if we can not make good use of it, it can affect our study. It may make us lose interest in our study. Spending too much time on it will not only affect our study but also does harm to our eyes.
In my opinion, we should make good use of it and make it a good tool for us to use.
