Grammar 知识精讲 used to的用法 （Page 28） 构成 used to + 动词原形 He used to play basketball after school. 他过去常常放学后打篮球。 用法 表示过去的习惯动作或状态，暗含现在已不再发生或不存在。其中to为不定式符号，后接动词原形 He used to be a very poor man.他过去是一个很穷的人。（暗指现在已经不穷了） 句型变化 否定句 Used not to, usedn’t to 或didn’t use to She didn’t use to have long hair.=（She usedn’t to have long hair.） 她过去不留长发。 一般疑问句 Did sb. use to...?/Used sb. to...? Did you use to play the piano?=Used you to play the piano? 你过去常常弹钢琴吗？ 反意疑问句 附加疑问部分可用didn’t或usedn’t He didn’t use to drink, did he? 他过去不经常喝酒，对吗？ He used to drink, usedn’t he? 他过去常常喝酒，对吗？ 相似短语 be/get/become used to doing sth. 习惯于做某事 My grandfather is used to going for a walk after dinner. 我爷爷习惯于饭后去散步。 be used to do sth. 被用于做某事 Wood can be used to make paper. 木头能用来造纸。 【魔法记忆】口诀法记忆used to：过去常常used to，既无人称也无数；后接动词用原形，否定形式两情形；didn’t use to是其一，used后加not也可行；疑问句结构更简单，借来Did句首添。 【典例】She used to __________ a bus to school, but now she is used to __________ to school. A. taking; walk B. take; walk C. taking; walking D. take; walking 【答案】D 【解析】used to do sth.是固定搭配，过去常常做某事；be used to doing sth. 习惯于做某事；be used to do sth.被用于做某事。句意：她过去常常坐公交车去上学，但是现在她习惯于步行去上学。 能力拓展 一、单项选择 1.
