Question

When you read a text, you'd better make a mark____you don't understand A.where. B.in which 答...
When you read a text, you'd better make a mark____you don't understand
A.where. B.in which
答案是A,为什么不选B?in which,where的区别在哪里?不是which限定性和非限定性都能用吗?

Answer 1

.
用in which=where是有一个前提的,那就前面有表示地点的词,而which指代的就是这个“地点词”,而本句没有,所以只能用where
比如：I like the place in which /where you live.
