First, disrespect for teachers.
? I didn't study hard when I was supposed to learn knowledge, so it is normal that I can't find a satisfactory job after graduation. As college students, we should have self-control to manage the problem of playing mobile phones. You can't neglect your studies. Learn more knowledge and beg less in the future.
? Playing mobile phone in class is disrespectful to teachers. As the basic etiquette of college students, it is also the failure of being a man. It is disrespectful for teachers to play mobile phones in class. Ideological and moral education teaches us to respect the fruits of others' labor from an early age.
Second, environmental factors.
? It is normal for college students to play mobile phones in class. No matter which university or class, students may play mobile phones in class. The reason why students play mobile phones is because of environmental factors. Many people in our class play mobile phones in class, so that some boys can't help playing games together in class.
Third, the disadvantages of playing mobile phones for a long time.
1, radiate the body;
As we all know, mobile phones have radiation effects. When the magnetic field of mobile phone is close to human body for a long time, our bones will deform and bend, resulting in pain symptoms. The radiation effect of mobile phones will also affect the development of the brain, and in the long run, there will be a phenomenon of mental decline.
2. Distraction;
? The harm of mobile phones goes far beyond physical harm. Walking and playing mobile phone will distract attention, lead to inattention, affect work efficiency, and even lead to emergencies.
3. Hearing loss;
? We use mobile phones for a long time. If the double talk is too loud, it may affect our hearing and lead to hearing loss. Many people use mobile phones as a tool to watch videos and listen to music for a long time, but wearing headphones will affect our overall hearing, which is not conducive to the good development of our eardrums and even lead to hearing loss.
? Therefore, it is not easy for college students to play mobile phones. We must study hard and discipline ourselves.
