Nowaday, the life is modern. Smart phones and computers are very popular and they appear all around us. Using smart phones is a necessary part of many students' life. We can use them for relaxing, connecting and especially studying. Students can learn in the Internet, search information for their lessons,... Using smart phones can solve many problems quickly and easily. But, there is a problem.Some students mostly use smart phones to relax and spend less time studying. They concentrate on the smart phones instead of keeping their eye on learning.

The rules not only help students be focus on learning, but also study effectively.
