      九年级新目标（go for it ）－ Unit 2。I used to be afraid of the dark .
      (Section A.1a)
      1. used to do sth “过去常常”（表过去习惯性动作或状态，暗示现在已不再如此，既可作情态动词，又可作实义动词。）
      e.g. He used to go swimming on Sundays ,didn’t / usedn’t he ? ( 反义疑问 )
      否定式：used not to do 或didn’t use to do
      e.g. He used not to play basketball .= He didn’t use to play
      basketball.（他以前不打篮球）
      一般疑问式：Did …use to ? 或 Used …to ?
      e.g. Did you use to have long hair ? = Used you have to have long hair ?
      辨析： be used to doing sth“习惯于做某事” e.g. He’s used to getting up early .
      be used to do “被用来做…” e.g. This room is used to be a living room .
      be used for ( doing)… “被用作…（目的，用途）” e.g. Wood can be used for making paper
      .
      be used by… “被某人使用” e.g. French is used by Frenchmen .
      比较： used to do& would do
      ① used to和would都可表示过去的习惯或行为，常可换用。
      e.g. They would often hike into the mountains .= They used to hike into
      the mountains .
      ② used to含有较强的“今昔对比”的含义，而would无此含义
      e.g. I do not swim so often as I used to我不像过去那样常游泳了。（不能用would代替）
      He would sometimes work into the night. 以前他常工作到深夜。（不表示现在他不工作到深夜）
      ③用would时，有时应有时间状语来加以限制，而used to则可无时间状语
