There are many possible answers to this question because different teachers and schools may have different views and regulations. The following are some possible reasons: 1. The school rules prohibit electronic devices from entering the school, including comics and novels. This could be because the school was worried that students might use electronic devices inappropriately on campus or be addicted to these works, which would affect their studies. The school believes that the content of comics and novels is not suitable for students to watch and may distract students from their classroom studies and homework. Some comics and novels may contain violence, eroticism, or other inappropriate content, which may cause dissatisfaction or discomfort among students. Schools may be worried that comics and novels will negatively affect students 'eyesight. Reading comics and novels in school classes may cause students to frequently look down at the screen and negatively affect their vision. 4. The school may think that comics and novels require additional storage space and maintenance costs, which may increase the school's expenses when used in the classroom. It is important to note that these are just some possible reasons. The specific reasons may vary by school, grade, and course. If the teacher thinks that comics and novels are not suitable for use in class, they may explain this to the students and allow them to read them after class or during self-study time.
