Question

定语从句where和介词+which的区别

Answer 1

在表示地点或抽象地点时可以互相转换。如：
(2005上海)If a shop has chairs_______women can park their men, women will spend more time in the shop. 此处选where，等于on which
(2003上海)I can think of many cases_______students obviously knew a lot of English words and expressions but couldn’t write a good essay.
　　A. why B. which C. as D. where
　本题中的先行词是表示抽象地点的cases（实例,情况）,定语从句中不缺主语或宾语,用关系副词where或in which,故选D.
但在某些词组中的介词提前，不能用where。如：
He bought the book in which he was interested. 不能用where

Answer 2

At all events, the two latter are of less frequent occurrence.
