1. First, students have no clear understanding of imagination and are in a fragmented state. Therefore, it is unscientific and arbitrary for the teaching principle of "being good and tempting" to play its due positive role.

2. Second, the conventional and scripted teaching methods lead to dull classroom atmosphere, depressed learning mood, and students' thinking is confined in a narrow space.

3. Third, students' self-study time is plundered by mechanical repetitive homework or weird questions.

Extended data

To get out of this predicament, we must work hard on expansion. Some experts believe that in order to encourage students to read more popular science books, schools should not lock up the library and let it play its full role; Give students time to read extracurricular books and give them more study space.

Teachers should also pay attention to art when inspiring students' thinking, and sometimes "citing without sending" can make students' thinking gallop freely in the infinite space-time field.

The so-called "citing without sending" means that when students' understanding of the text reaches a certain depth, teachers guide students' thinking to advance in depth by inspiring, asking questions and assuming, thus stimulating students' new thinking excitement. Therefore, teachers should make their guidance full of strong interest, so as to stimulate students' curiosity and thirst for knowledge and fully mobilize students' subjective initiative.
