story 與 floor 的差別
某建築物有幾層樓要使用 story
例: a five-story building
five-story 複合形容詞 story 恆用單數
例:
Their new house has for stories, including the attic.
~~~~~~~~~~~~~~
表示在幾樓則要用 floor
例: on the fifth floor
My office is on the eighth floor.

例:
The proposed 41-story skyscraper will become the city's tallest structure.
