一道定语从句题(急!)
In our university there are several big parks _we students can go to enjoy the beautiful scenery. A.to which B.at which C.from which D.in which
我知道选A
我只是想问,为什么D不对?we students can go to enjoy the beautiful scenery为什么不能当做一个整体?非要拆开?有什么理由吗?

we students can go to enjoy the beautiful scenery中的to是不定式做目的状语,而to which的to是和go 连着,go to parks,which代表的是parks,go 不与in连用,所以不能用D
