同学你好，
简单的听写了一下，供同学参考：Do you know what residential halls are? college students often live in residential halls or dorms. Campus dorms are with primary resident assistants, RAs which are 3rd or 4th year students, who live in a dorm as a part of the residence steward and managers on-campus housing. RAs help to supervise the students in the dorms as one as providing assistance and supporting students who have personal academic troubles。

意思：你知道什么是学生公寓吗吗？ 大学生经常住在宿舍或宿舍。 校园宿舍有居民助理，RA是3年级或4年级学生，住在宿舍作为住宿管理员和校园住房管理人员的一员。 RA帮助监督宿舍中的学生，如提供帮助和支持有个人学业困难的学生。

希望帮到你！
