    將來完成時
      1.概念:在將來某一時刻之前開始的動作或狀態(tài)
      2.時間狀語:by the time of;by the end of+時間短語(將來);by the time+從句(將來)
      3.基本結(jié)構(gòu):be going to/will/shall + have done
      4例句:By the time you get back,great changes will have taken place in this area
    先A
    has 跟在be going to will shall 后面變動原形即have
