easier, but they also bring problems. Many students spend too much time on smart phones because
they have no self-control. This may have a bad influence on their studies. Besides, using smart phones
too often can do harm to their health, especially to their eyes. For our health and studies, I think we
should reduce the time we spend on smart phones. In our free time, we can stay with our friends or
family. We can also take up some hobbies. Taking part in all kinds of after-school activities is also
a good choice. In a word, let's make full use of our spare time and don't let smart phones control our
lives.
