高手请给个正确答案

Answer 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 numbers D. room numbers

选D。number加复数是因为有2个房间所以有2个号码，而room不能改成room's，这和pencil box或者school bag是一样的道理，用原词。

Answer 2

d room numbers
room 作定语用单数，而number因为是两个，所以用复数

Answer 3

D
在主要名词上变复数

Answer 4

d
