The clever boy made a hole in the wall,_______ he could see what was going on inside the house.

问题描述:

The clever boy made a hole in the wall,_______ he could see what was going on inside the house.
A in which ,that
B on which,what
Cthrough which,what
D at which,that
,但我想问为什么不选A、D呢?in which不是在……里面的意思,at which不是在……里面或在……上面的意思吗
请大家详细分析每个选项,不复制别人回答,

其实through which 就够了,what多余.which代表hole,through表示通过洞来看.in on at 都不表通过.
这个句子真是很猥琐,描述了男孩的偷窥情节,还有through 和 hole 这样的字眼,还搞得人很困惑,出题者用心不良.为什么不通,在洞里面看,所以A、D也合适啊问题在hole,和see,肯定通过洞来看,而不是在洞里面看,或者在洞旁边来看,因此用through。不要太纠结这个问题,知道就行。
