文档介绍：一、知识点
1. used to  过去常常做某事,暗指现在已经不存在的动作或状态. 后跟动词原形. used to do sth.
  There used to be ….(反意疑问句)didn’t there?
否定形式为: didn’t use to 或 usedn’t to
疑问形式为: Did…use to…? 或 Used…to…?
be/get used to doing , to 为介词.
2. wear 表示状态. =be in +颜色的词
put on 表示动作.  
dress + sb. / oneself
have on表示状态(不用于进行时态)
3. on the swim team  on 是…的成员,在…供职.
4. Don’t you remember me?  否定疑问句.(考点)
 Yes, I do. 不, 我记得.  No, I don’t 是的, 我不记得了.
5. 反意疑问句:
①陈述部分的主语为 this, that, 疑问部分主语用it; 陈述部分主语用 these, those, 疑问部分用they 做主语.
例: This is a new story, isn’t it?
  Those are your parents, aren’t they?
②陈述部分是 there be 结构, 疑问部分仍用 there
例: There was a man named Paul, wasn’t there?
③ I am 后的疑问句, 用aren’t I
例: I am in Class 2, aren’t I?
④陈述部分与含有 not, no, never, few, little, hardly, seldom, neither, none 等词时,疑问部分用肯定.
例: Few people liked this movie, didn’t they?
但陈述句中若带有否定前缀或后缀的单词时, 这个句子仍视为肯定, 后面仍用否定.
例: Your sister is unhappy, isn’t she?
⑤陈述部分的主语若为不定式或 V-ing 短语, 疑问部分主语用it.
例: To spend so much money on clothes is unnecessary, isn’t it?
⑥陈述句中主语是 nobody, no one, everyone, everybody 等指人的不定代词时,疑问部分用they做主语; 若陈述部分主语是 something, anything, noting, everything 等指事物的不定代词时, 疑问部分用it 做主语.
例: Nobody says one word about the accident, do they?
  Everything seems perfect, doesn’t it?
⑦当主语是第一人称I时, 若谓动为think, believe, guess 等词时, 且其后跟宾丛,这时疑问句部分的人称, 时态要与宾语从句保持一致, 同时还要考虑否定转移.
例: I don’t think he can
