帮我把这段话润色一下：国内小学教师与英国、美国等国家的教师相比，工作范围更为广泛，边界更为模糊，但与日本中小学教师较为相似，除了日常教学外还要承担学校经营、学生管理等“周边工作”，有时甚至难以保证正常的教学和休息时间

Compared with teachers in the United Kingdom and the United States, primary school teachers in China have a wider range of responsibilities and a more ambiguous job boundary. However, they are more similar to middle and primary school teachers in Japan, as they not only undertake daily teaching but also peripheral work such as school management and student administration. At times, it can be difficult to ensure normal teaching and rest time due to these extra responsibilities.
