   将来完成时


  将来完成时是用在表示在将来某一时间以前已经完成或一直持续的动作。经常与before+将来时间或by+将来时间连用,也可与before或by the time短语引导的现在时的从句连用。
  重点理解:
  状态已完成:表示某事持续到将来某一时为止一直有的状态。并在将来完成。
  动作完成:表示将来某一时或另一个将来的动作之前,已经完成的动作或已经对动作产生一定的影响。
  基本句型
  shall(第一人称)will(第二、三人称)+have+过去分词(done)
  例句:They will have been married for 20 years by then.
  到那时他们俩结婚就满20年了。
  You will have reached Shanghai by this time tomorrow.
  明天的这个时候你就到上海了。
