all of your rooms与all your rooms有不同吗

A：Just a moment… Ok, so you currently have the DX405 in all of your rooms. Will you be wanting the same model?

B：Yes, please.

A：And installation as well?

B：Yeah, sometime next month after we finish the remodeling.

A：Alright, that should be fine. I’ll get you a quote and email it over.

B：Thanks!

all of your rooms,与all your rooms表达的意思是否一样，有不同吗？

all of your rooms,与all your rooms表达的意思基本一样。

all of your rooms中，all是不定代词，为中心词，of your rooms 为后置定语，of表示部分与整体关系。

all your rooms中，all是前位限定词，中心词是rooms.

因此，假如说二种结构有细微差别的话，则前者强调 all, 后者强调 rooms.
