Please write a composition according to the negative effects of using mobile phones on students.

As more and more middle school students in large and medium-sized cities have mobile phones, SMS, a convenient and fast communication method, has penetrated into their lives. Many students fall in love with their mobile phones and have no intention to study, which affects the physical and mental health of middle school students to some extent.

According to a survey, 60% of the short messages sent and received by students are spam messages unrelated to normal life and study. About 64% of them are "colored" information and boring news, in addition to feudal superstition and fraud information.

Spam messages are having a negative impact on the establishment of middle school students' ideological and moral concepts, the formation of values and the establishment of a positive attitude towards life. Therefore, if a mobile phone is used improperly, it is no longer a mobile phone, but a Grenade.

Middle school students are full of longing for the future and eager to know whether their life goals can be realized. However, feudal superstitious information can easily make them make wrong judgments, while fraud and black business information can make middle school students doubt the principle of good faith and have a one-sided understanding of society.

What is terrible is that middle school students don't know enough about the harm of spam messages to their healthy growth. In the survey, nearly half of the students think that this kind of information has no influence on themselves, and "it's just a text message, just for fun, it's no big deal." Only 14% students think it has a great influence on themselves.

It can be seen that it is negative for students to bring mobile phones. Middle school students bring mobile phones to school, which will mostly affect their study. It is ok for students to buy mobile phones, but it is best not to bring them to school. And it can't affect your study, because reading is the most important thing.
