two -week和two weeks区别是什么

two -week和two weeks区别是什么

two-week,把两个星期作为一个时间,就是单数化;

two-weeks,是错误的表达;

two

weeks,两个星期,是复数;

two

week，是错误的表达。。

呵呵。。

two weeks=两个礼拜

two-week = 两个礼拜（长）的X

比如，

"He is in Shanghai for two weeks." (他会在上海呆两个礼拜）。

"He is in Shanghai for a two-week English course." （他在上海参加一个为期两个礼拜的英语课程）。
