    02 二、把握used to用法。
weigh的用法
    used to do sth. 过去经常做某事,它没有人称和数的变化。
    其用法有三:
    1. 表示过去存在而今不复存在的习惯行为或状态,意为:“过去经常”,其中to不定式符号,后接动词原形,表示今昔对比。如:
    I used to walk to school, but now I am used to taking the school bus to school.

    2. used to 与there be 结构连用,表示“过去存在的状态”,而现在不存在此类状态了。如:
    There used to be a lot of trees here.这里原来有很多树。(意味着现在没有了)
    3. used to 与always, often, sometimes等频度副词连用时,并非表示现在的动作或现在的习惯,仍表示过去习惯、过去常常反复发生的动作或存在的状态。如:
    She used to write to her father with pens. 她过去常常用钢笔写信给她父亲。
    03 三、把握used to 的句子结构。
    1. used to的确定句结构
    主语+used to+动词原形……如:
    I used to go to the cinema, but I never have time now. 我过去常常去看电影,但现在没有时间了。
    2. used to的否定句结构,其否定结构有两种形式。
    ⑴ 主语+did not use to+动词原形……,这种否定句型,就是把used当做实义动词来看,所以变否定句要用助动词did,是美式英语用法。如:
    You used to drink. →You didnt use to drink.
    ② 主语+used not to+动词原形……,这种否定句是把used当做情态动词,变否定句直接在used后面加not即可,used not可以缩写成usednt,是英式英语用法。如:
    The shop used to open on Sung\days.→ The shop usednt to open on Sunday.
    3. used to的一般疑问句结构,其一般疑问句有两种形式。
    ⑴ Did+主语+use to+动词原形……?这种一般疑问句,就是把used当做实义动词来看,所以变一般疑问句时要用助动词did,是美式英语用法。如:
    I used to go swimming in the river when I was young.
    →Did you use to go swimming in the river when you were young?
    ⑵ Used+主语+to+动词原形……?这种一般疑问句是把used当做情态动词,所以变一般疑问句时,直接把used提到句首,是英式英语用法。如:
    He used to go to school by bike.→ Used he go to school by bike?
    4. used to 的确定和否定回答结构。
    used to用于省略句时,确定式保留to,否定式不保留to。如:
    —— Used you play basketball? 你过去常打篮球吗?
    ——Yes, I used to.(No, I usednt.) 是的,常常打。(不,不常打。)
    5. used to的反意疑问句,其反意疑问句有两种形式。
    ⑴ 在附加疑问部分中借助于助动词did构成,这种反意疑问句,就是把used当做实义动词来看,所以变反意疑问句时要用助动词did,是美式英语用法。如:
    She used to go to work by bus, didn’t she?
    She didn’t use to do it, did she?
    ⑵ 在附加疑问部分中直接使用usedn’t。这种反意疑问句是把used当做情态动词,所以变反意疑问句时,直接用used,是英式英语用法。如:There used to be a bookshop here, usedn’t there?
