vacancies
A vacancy is a job or position that has not been filled.
Most vacancies are at the senior level, requiring appropriate qualifications.
大多数空缺的职位都属高层,这需要适当的资历。
If there are vacancies at a building such as a hotel, some of the rooms are available to rent.
This year hotels that usually are jammed had vacancies all summer.
那些以往常常爆满的旅馆在今年整个夏天都有空房。
