It is not a good habit to point your fingers to the place_____you read.
问题描述：
It is not a good habit to point your fingers to the place_____you read.
A at which B at where C.which D where
为什么不选A,选D?
如果where 不等于at which，那么应是哪个介词加which?
答
这句话的意思是“把手指放在（书上）你正在读的地方是个不好的习惯”,where是副词,相当于介词加which,read在此处是个不及物动词,所以后面跟副词where.
