英语题请解释

he hid himself behind the door {D } he still could see what would happen to his classmate.
a.there
b.which
c,from which
d.from where

我做这种句子的时候有个窍门
把后面的句子提上来
He still could see what would happen to his classmate from (the place)/where
希望这样你能看懂。。

C

定语从句，因为把which还原的话，从句意思就是he still could...from behind the door.

我觉得1楼解释有问题。1楼举的例子是from引导的宾语从句，但楼主这句话是针对door写的定语从句，不能随便改动前后语序，解题方法更不能一概而论。

C

c
---he still could see what would happen to his classmate THROUGH THE DOOR
所以定语从句就变成-----the door which he still could see what would happen to his classmate THROUGH
再变把THROUGH提前------the door THROUGH which he still could see what would happen to his classmate

答案是C。
首先，根据句意，后面这个句子是对前面句子中DOOR的修饰和限定，也就是说是他的定语从句。
哪么首先排除掉THERE。然后我们可以看出，后面句子跟DOOR的关系是从门缝中仍然能看到发生的，所以应该是FROM THE DOOR。那么也就排除了B。
最后，既然有了FROM， 那么它后面需要接名词或代词。而WHERE是引导副词，所以只能选C

应该是C,定语从句
