英语语法问题十分费解

Our class room i s lighter than that the next door.

本题有人说在that

后加of

有人说改为the one

有说改为that one

到底改为什么？

问题补充：

Our class room i s lighter than that next door.

哦题干没有the是next door

答：这是一道有问题的题目。

如果意思是：我们教室比隔壁的明亮。则：

Our classroom is brighter than the one next to ours

可惜得很，楼上所有的人都没有注意到形容词的误用。lighter显然为brighter之误用，因为light作形容词是轻的，淡的，用来修饰classroom, 头一次见到。

而next-door是作前置定语用的：in or being the next building, exp. in a row: next-door neighbours

next door adv. 要后置：the neighbours next door= the people living next door.

next door不作名词和，如作名词 The next door则为‘下一扇门’，比较对象不对称。

所以我认为要避开隔壁（next door）这个语言定式，象我那样改比较好：the one =the classroom next to ours.

或更简洁的：

Our classroom is brighter than the next one.

不过，our与the next也不对称。应our与their对称。
