Now China advocates frugality and refuses to waste, not only saving food on the table, but also involving all areas of life. In the field of teaching, the waste of paper textbooks is extremely serious. Every graduation season or the end of the semester, there are usually aunts on campus who recycle old books that students don't want, and then make money as waste. Students are also willing to reduce the burden and clean up the site quickly to make room. As a tool to transfer knowledge, teaching materials are not just paper, but the contents inside can still continue its mission. In order to prevent educational books from becoming waste paper, it is necessary for producers, transmitters and users of teaching materials to deeply understand the harm of book waste and actively take relevant measures.

A tree can make thousands of pieces of paper in a few decades, and a corresponding tree can indeed make dozens of books, but do you know how much paper China needs? A student can fill a big box with all kinds of books and papers he has learned. The amount of paper used by hundreds of millions of students in China is amazing. It takes time cost, labor cost and production cost for a tree to grow into a teaching material. ? From the school level, schools should order on demand, follow voluntary choice when it is not necessary, and arrange the amount of learning tasks reasonably. In addition to some books distributed free of charge by the nine-year compulsory education country, for students, the school will require students to order other teaching AIDS through teachers. Appropriate guidance books can indeed provide students with high-quality exercises and more thorough and understandable analysis, but when the number reaches an unbearable level, many teaching materials will be wasted. For example, the college entrance examination is still two months away, and it is unreasonable for teachers to have several sets of test papers besides the simulation questions that need to be practiced on weekdays. In the end, students wasted money but threw it away because they didn't have time to write. ? From the perspective of teachers, it is necessary to supervise students' use of textbooks and improve the utilization rate of textbooks. It is a waste to throw away many textbooks after reading them, and it is also a waste to have some textbooks without writing a few questions. Many students have poor self-control. The school wants to cultivate students with all-round development in morality, intelligence, physique, beauty and labor, and has issued many non-professional books, such as music, art and physical education, but they have not studied deeply, and most of them are new and without trace.

? From the students' point of view, we should cherish books, give full play to their functions, and then pass them on to others for recycling. Although some books pass on the book knowledge to a student, the knowledge remains unchanged and will never become waste. You can continue to show it to other students, which will test their sense of responsibility and economy.
