1.With the students themselves, it is necessary to have a sense of self-discipline in learning, making a clear distinction between play and learning. Using the phone with the right purpose, used to look up information for the study, contact with relatives, friends, healthy entertainment. Always try to practice and cultivate morality, do not waste too much of your time on useless games on the phone, but should be diligent in communicating with teachers and friends, taking care of your father's family. Mom, spend time reading to nourish your soul.

2For parents who need to specify the age to use the phone, check the time and behavior of their children when using the phone to prevent the actions going too far.

But phones, because no matter what, they have a lot of benefits if we use them properly. The need to change here is to find ways to educate, change students' perceptions, explain and guide them to use phones in a correct and healthy way. Parents need to care more closely with children, management but does not mean invading privacy, it only makes children more opposition.

1) I think that is not true, we have to limit the use of modern technology, especially the age of school students like us, if not limited, we will be addicted to play. Too much or badly in school, and then gradually become social evils that do not help the family

2)no, they shouldnt, the teenagers want to making, playing or......something alone or with their friends and their sister or their brother but the adults shouldnt decide how teenagers spend their time
