我认为UNTIL RECENTLY ,跟完成时态表示持续的动作,跟完成事态绝对没有错,但对于瞬间动作来说就需要过去时 但LED这属于瞬时动作(就象continue不能跟进行时态一样),应该用过去时态,导致只是一次或短暂的瞬时动作,不是持续的 A)持续的:until recently, my gym experiences have been good until recently I have been using recycled paper bedding from the store. B)瞬时的:until recently, then I watched it on VCD. until recently, one of the lenses dropped when i was driving at the PG Bridge. 纵上LED用过去时是没有任何错误,只是要根据具体情况而来 所以选A
