一个集体就像一个原子。原子是由原子核和核外电子组成。原子核居于中心，而电子运动其周围。原子核吸引核外电子的能力越强，原子就越稳定。在班集体中，班主任是原子核，学生是核外电子。显然，一个优秀班集体的凝聚力、向心力、战斗力主要决定于班主任这个核心的吸引力。班 A collective is like an atom. Atoms are composed of atomic nuclei and extranuclear electrons. The nucleus resides in the center and the electrons move around it. The more powerful the atomic nucleus attracts extranuclear electrons, the more stable the atoms will be. In the class, the head teacher is an atomic nucleus and the student is an extranuclear electron. Obviously, the cohesiveness, centripetal force, and combat effectiveness of an excellent class group mainly depend on the core attraction of the class teacher. class
