holiday 是可数名词,故前面要加a,
加油!不明白再问!The students will have ______ during May Day. A. five days holidayB. five-day holidayC. five days' holidayD. five day holiday 请问那这个题又选哪一个呢？C 五天的假期If I'm free, I'd like to spend _____ holiday in the country. A. two days' B. two-day C. a two-day那么这个题为何只能选C而不选A呢，和第二个问题有什么区别吗？我认为这个问题A和C都可以所以一直很纠结。two days' holiday = a two -day holiday那就是A和C都可以啦这道题是
