The college entrance examination is a selective examination. It is necessary to consider how to effectively distinguish students of different levels and let them go to the corresponding institutions respectively. If a piece of paper is to be used all over the country, it will become very difficult to write this question, because students in different regions have different degrees of acceptance of the difficulty of the test questions. If the topic is difficult, many students will not do it; The topic is simple, and it is difficult to effectively distinguish the level of students.
