作为开学的舍长，首先要维护宿舍的秩序和安全。要对新生进行各种相关的宣传，如宿舍规章制度和消防安全等。同时，还需与宿管老师密切合作，协助解决学生的生活问题和管理宿舍。
另外，舍长还应该包容学生的差异，妥善处理同学之间的矛盾和纠纷，并且要积极组织和开展各种形式的文娱活动，促进同学们之间的交往和交流，增进大家的友谊和感情。总之，舍长的工作是一项重要的责任，需要具备一定的领导和组织能力，并且要以身作则，成为同学们的表率。
如果舍友要求换床，可以先询问原因，如果合理且不影响其他人，可以考虑协商换床。但如果不合理或影响他人，可以委婉地表达自己的立场和考虑，寻求双方都能接受的解决方案。
The new term has started and the beginning of the school year means that we must grow and gain something in these new years.
Students should study hard, develop their moral, intellectual, physical, social and aesthetic skills in an all-round way, so as not to worry their parents and give themselves a good start in life.
Teachers must remain patient with their students, teach the children with sincerity, lead them into the sea of knowledge and help them become pillars of society.
