高中英语特殊句型句式中的“时态”解题方法 一、“for +一段时间”句中的时态 “for +一段时间”一般和完成时连用，但如果是一些延续性动词如 be, play, work, study, live 等，它们的过去时就可以与“for +一段时间”连 用，表示过去的某种延续状态，相当于过去完成时。如： He played football regularly for many years when he was young. 二、if 和 when 引导状语从句和名词性从句时的时态 if 和 when 引导条件状语从句和时间状语从句时，从句用一般现在 时代替一般将来时；引导名词性从句时，要根据具体的语境确定需 要的时态。 如： —Do you have any problems if you are offered this job? —Well, I’m thinking about the salary ... As soon as he comes back, I’ll tell him when you will come and see him.
