问题描述：
定语从句 where
1 i am interested in all that you have told me .
这句为啥是定从不是宾从,all that you have told me 不是作in的宾语吗
2 the speed at which the machine operates is indicated on the meter.
可以换成the speed which the machine operates at is indicated on the meter吗
3 this is the place where i spent my childhood.
this is the place which i visited last summer,
为啥第一个用where 第二个用which 呢
THX!
