over the next few years与over the past few years

over the next few years与over the past few years
有一道高考题大概是：Our relationship will____ a lot over the next week.
A,develop B,have developed 为什么不选B,有了over不就用完成时吗!?
因为over the next few years的时间是【从现在起往后算的接下来的几年】,一般用于【将来时态】；而over the past few years的时间是【从过去某个时间开始截止的到现在】,一般用【现在完成时】.上面这句是将来时态,所以选项是A.
还有一句话The work will be completely finished by next Monday.
by 的时间是从动作发生时算起截止到下个星期一为止,所以用【将来时】.
