24. He was hiding behind the door _________ he could see what was happening.
A. which B. from where C from which D. where
为什么不选D?
1选A缺的是主语,所以用what,what is more important可以当做固定词组来记
2C这是as...as结构,解释为和.一样多,不用that的
3选C这边就是一个简单的比较结构,比较级后面加的是than,不是which
4选B解释为从门后面看到,所以要加from,原来先行词在从句中就是做状语的,所以是from where
有不会的可以再问我
