two miles✀ 与 two-mile 作形容词的区别

two-mile 只能做定语,前面通常有不定冠词a,如:there is still a two-mile walk

而two miles'也可以做定语.但前面不能有不定冠词,如:Beijing is two miles's away.

如果你要说某地离这里有2英里远
那就是the place is two miles away from here.
the place is two miles' walk from here.

而如果你要说某样东西有2英里~注意是这样东西本身有2英里~那就是sth is two mile
这时候要用two-mile就要说a two-mile ...

但是实际上这两个词是一样的，你可以说a two-mile-long road也可以说a two miles' road

two-mile是个复合形容词，就好像*-year-old一样~是前置定语(一个两岁的小女孩：a two-year-old girl)

two miles' 是一个所有格(名词是复数)
two-mile 是复合名词

只是写法不同 实则没有任何区别哦！ 呵呵
祝楼主开心：）

two-mile 通常在前
