The family that I'm staying with lives in town.这句话什么意思这句话中family指的是家庭还是家人,that可不可以换成who或which

1.The family that I'm staying with lives in town.
翻译:和我待在一起的那个家庭生活在城里.
2.
1）family作为“家庭”讲时,指物,是个体名词,有复数形式families.
如：There are 30 families in this building.
2） family作为“家人”讲时,指人,是集体名词,本身无复数形式,但是表示复数概念.
如：Your family are your best friends.
3.从句中的动词三单lives来看,此处暗示主语为单数,所以翻译成“家庭”；它既然指物,所以可以换成which,但不能换成who.
