This is the school that we visited last year和Thi
This is the school that we visited last year和This is the school where i studied three years ago.这两句的引导词第一句中为什么不能用where呢?两句that和where为什么不能互换,老师说不能.不太理解,
答
因为第二句用where是因为后面动词是studied,先行词是the school,不能是studied the school ,the school前还应有个介词in,所以这里的where是等于in which!而第一句用that是因为后面动词是visited,可以直接说是visited...
