“五星酒店”到底是“five star”还是复数“five stars”？

我们出门在外肯定是避免不了住酒店的，
虽然好像还没有住过五星级的酒店，
但是关于五星级酒店的小知识还是需要掌握的，
所以赶紧跟随小编来学习一下吧~

五星级的正确表达是：Five-star

If you change the word order, you have to add or remove the “s” from stars:
如果你改变词序，你就必须添加或删除s：

✦That hotel is rated five stars.
那家酒店被评为五星级。

✦We stayed at a five-star hotel.
我们住在一家五星级酒店。

This is because 'star' is functioning as an adjective, and not as a noun. You can say that you saw 'Five stars' shining in the sky. But when a noun like hotel follows the word 'star' , you say, 'I had dinner in a three star hotel'. You do not say, 'three stars hotel'. Similarly, you say, 'I want five rupees'. But when the word 'rupees' is followed by the noun 'coin' or 'note' , you say, 'I need a five rupee coinnote'. You do not say, 'five rupees note'. Joggers talk about a 'twenty-mile marathon', and not a 'twenty miles marathon'.

这是因为star是形容词，而不是名词。你可以说“你看到了five stars在天空中闪耀”。但是当像hotel这样的名词跟在star后面时，你会说，“I had dinner in a three star hotel”。你不会说，“three stars hotel”。同样地，你说，“I want five rupees”。但是，当单词“卢比”后面跟名词“coin”或“note”时，你就会说，“I need a five rupee coinnote.”。你不能说“five rupees note”。慢跑者说“twenty-mile marathon”，而不是“twenty miles marathon”
