新目標九年同步講解與測試

    如果動詞（或動詞短語）相同，則第二個動詞可省略。（if the second verb phrase has the same verb, you can omit it.）
    ·she used to live in london, but she doesn’t anymore.
    anymore可不與used to連用（you can use anymore without used to）
    ·she doesn’t live in newyork anymore.
    anymore只能和否定詞連用
    ·we don’t go there anymore.
    ·they never talk to me anymore.
    ·no one likes him anymore.
三、still
    我們用still來說明某人或某物沒有變化。（use still to show that something or someone has not 
changed）
    she still lives in mexico.
    still應放在主要動詞前面（use still before the main verb）
    he still lives in new zealand.
    still應放在be動詞后面。
    he is still crazy after all these years.
    still 應放在像can, may, should這樣的助動詞之后
    she can still play the piano.
四、頻率副詞
    頻率副詞（如always）在句中位置不同。（adverbs of frequency can appear in different 
positions in a sentence.）
    它們的位置應是：在主要動詞之前，在be動詞之后，在助動詞（will, can, have等）之后，在used to
之前。
    ·i usually get up at six.
    ·you were rarely happy. 你很少高興。
    ·you will sometimes hear from them.
    ·i have seldom spoken to her.
    ·they never used to dance.
    ·he always used to call her.
五、詞語辨析
  1. used to和would
    ①used to和would都可表示過去的習慣或行為，常可換用。
    when we were children we used to/would go skatingevery winter. 我們小時候每年冬天都去滑
冰。
    ②used to含有較強的“今昔對比”的含義，而would無此含義
    i do not swim so often as i used to
    我不像過去那樣常游泳了。（不能用would代替）
    he would sometimes work into the night.
    以前他常工作到深夜。（不表示現在他不工作到深夜）
    ③用would時，有時應有時間狀語來加以限制，而used to則可無時間狀語
    he would go to see mother every vacation.
    （那時）他每個假期去看望媽媽
    he isn’t what he used to be. 他不再是過去的他。
  2. used to do和be used to doing.
