A.off and on B.on and up C.about D.at least

A

on and up 没有这个说法
如果用about就应该直接跟时间，而不会中间加个for
at least,至少。道理同about

所以选off and on: adv.断断续续地

赞成楼上的看法。已经很正确了:>

对，选A

how long have you____? how long have you been 用法 How long have you been skating? How long have you been collecting shells？与How long have you collected shells?的区别 how long have you been here 和 how long have you stayed here 的区别 how long have you been keeping this to yourself? How long have you been married? 你们结婚多久了？ how long have Liji and Guoda been married? How long have you been like this?是什么意思？ How long have we been run?错在哪里
