how long have you been 用法
how long have you been ---work?
A at B on C in D to
请教一下下,改选什么?为什么?
急!

驳been to work：
首先...就没有be to work这个词组(指这里和how long 连用的,偶知道be to do表将来 - -)
第2...have been to一般是"去过某地方"的意思,加地点
第3...作为go to work的持续性动词,并不是be to work
就像get to school不会变成how long have you been to school?
所以,偶觉得是been at work,因为本来就有at work "工作"这个表状态的介词词组,当然拿它和how long连用
意思仍然是:你工作多久了?
