Used to do sth
used to do sth
(一)肯定句式：
主语＋used to＋动词原形……
例如：I used to go to the cinema,but I never have time now.
我过去经常去看电影，但现在没有时间了。
He used to listen to pop music but now he likes rock music.
他过去总听流行音乐，但现在喜欢摇滚了。
(二)否定句式：
A)主语＋did not use to＋动词原形……
B)主语＋used not to＋动词原形……
第一种否定句型，就是把used当做实义动词来看，所以变否定句要用助动词did；第二种否定句是把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usedn’t或usen’t。
他过去骑车上学吗？
(四)used to用于省略句时，肯定式保留to，否定式不保留to。例如
——Used you play basketball?
——你过去常打篮球吗？
——Yes, I used to.(No,I usedn’t.)
——是的，经常打。(不，不常打。)
I don’t write to him now, but I used to.
B)Used＋主语＋to＋动词原形……？
美式英语通常用A种形式，英式英语用B种形式。例如

你小时候经常在河里hool by bike?

..。
例如：He used not to get up early。
= He usedn’t to get up early。
= He didn’t use to get up early.4、be（get，become）used to结构在意义上相当于accustomed to“习惯于"，从形态上看，used是个分词型形容词，to是介词,因此后面只能跟名词、代词或动名词。
例如：1)They got used to living in the countryside．他们已习惯于住在农村。
2)I've got used to being a vegetarian．我已经习惯吃素食.3）He is used to hard work．他习惯于艰苦工作.5、be used to表示“习惯于某事"的状态，而get used to则表示由“不习惯”到“习惯于"这一动态的过程，意思是：“（变得）习惯于"；“开始习惯于”。
