Question

关于名词作修饰语的
1).Jim was late for two classes this morning.He said that he forgot both of the ______.
A.rooms number B.room number C.room’s number D.room numbers
2).The newly-built library is a ______ building.
A.five-storey B.five storey’s C.five-storey’s D.five storeys’

Answer 1

1,第一个选D,Jim今天旷了两节课,可以从句中看出两节课在不同的教室,所以教室的号码也就不一样了.是复数,所以是room numbers.
2,第二个选A,five-story是第五层的意思,固定搭配,用法类似于：a-eight-year boy 一个八岁的男孩.本句话的句意是那个新建的图书馆是五层楼的建筑.
