三、still
    我们用still来说明某人或某物没有变化。（Use still to show that something or someone has not
changed）
    She still lives in Mexico.
    still应放在主要动词前面（Use still before the main verb）
    He still lives in New Zealand.
    still应放在be动词后面。
    He is still crazy after all these years.
    still 应放在像can, may, should这样的助动词之后
    She can still play the piano.
四、频率副词
    频率副词（如always）在句中位置不同。（Adverbs of frequency can appear in different
positions in a sentence.）
    它们的位置应是：在主要动词之前，在be动词之后，在助动词（will, can, have等）之后，在used to
之前。
    ·I usually get up at six.
    ·You were rarely happy. 你很少高兴。
    ·You will sometimes hear from them.
    ·I have seldom spoken to her.
    ·They never used to dance.
    ·He always used to call her.
五、词语辨析
  1. used to和would
    ①used to和would都可表示过去的习惯或行为，常可换用。
    When we were children we used to/would go skatingevery winter. 我们小时候每年冬天都去滑
冰。
    ②used to含有较强的“今昔对比”的含义，而would无此含义
    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
    He would go to see Mother every vacation.
    （那时）他每个假期去看望妈妈
    He isn’t what he used to be. 他不再是过去的他。
  2. used to do和be used to doing.
    ①be used to 是“习惯于”某一客观事实和状态，不强调动作，to是介词，后面接名词或动名词，
如：
    I am used to the weather here.
    我已经习惯于这里的天气了。
