答案

1,后面的从句你将它的顺序正常排列下就知道为什么了,就是he still could see what would happen to his classmate from the door,where 指代the door 地点状语从句而已.
2,这里的have其实起的作用相当于be,就是说相当于被动语态,说的是他们有座需要进行维修的桥.
3,就近原则,Are 和 you 来搭配
4,表示目的,有for不用of,为了寻找丢失的孩子,表示目的,所以不用of,have been doing表示一直进行的事情,到现在还没有停止,还要进行下去的意思,题目中强调的是结果,不是强调过程,所以不用doing的形式
