Question

----Dad,when will you be free?You agreed to go to the seaside with me four days ago.
----I am,Jean.But I think I will have a ________ holiday soon.
A.four-days
B.four-day
C.four days
D.four day

Answer 1

选择B选项
1.four-days 和 four day 这两种表达方式是错误的,用“—”连接的话就是一个单词 所以day不需要加S,反之,如果不用“—”连接,day就要加S
2.four-day 构成了一个形容词 可以用来修饰holiday
而four days 只是一个名词词组
类似的例子还有：
The boy is four years old .
He is a four-year-old boy .
