初一下沪教牛津版 【寒假专版】 A版知识点全解 寒假专版 【专题】used to do&didn't use to 语法专项突破 考频分析 初一下沪教牛津版中，used to do&didn't use to是基础语法点，考频占语法总量的8%左右，主要 分布在单项选择(1-2题)、完形填空(1-2题)、语法填空(1题)。在语境理解类题目中，used to do表示过去习惯性动作或状态与现在的对比，didn't use to表示过去未曾发生的动作或状态，是解 题关键。 考查内容 。结构与含义辨析：used to do表示“过去常常做某事”的肯定结构：didn't use to表示“过去不常做 某事”的否定结构，注意used to的否定形式需借助助动词did 。时间对比语境：强调现在与过去习惯或状态的对比，题干中常出现ow、but等提示词，需根据上 下文判断动作是否为过去经常性行为 。句式转换应用：陈述句与一般疑问句的转换(Did...use to.?),以及与一般过去时的区别(used to侧 重过去习惯，一般过去时强调过去某具体动作) 知识点一：used to do&didn't use to的用法 1.基本结构及含义 1.used to do sth.:表示“过去常常做某事”（现在已不做） 2.didn't use to do sth./used not to do sth.:表示“过去不常做某事”（否定形式，后者较少见） 3.例句： ●She used to live in London.(她过去住在伦敦。) 。He didn't use to wear glasses.(他过去不戴眼镜。) 2.疑问句形式 1.一般疑问句：Did+主语+use to do sth.? 初一下沪教牛津版 【寒假专版】 A版知识点全解 2.例句：Did you use to play basketball after school??(你过去放学后常打篮球吗？) 3.用法提示 1.后接动词原形，不可接动名词或不定式 2.无进行时和完成时，仅表示过去习惯性动作 3.例句： ·They used to go swimming every Sunday..(√) ·He is used to getting up early.(×,此句为be used to doing sth.结构，表“习惯于”") 知识点二：used to do&didn't use to的用法 1.基本含义 1.used to do:表示“过去常常做某事”（现在已不做），强调过去的习惯或状态与现在的对比。 2.didn't use to/used not to:表示“过去不常做某事”（现在可能做了），用于否定过去的习惯或状态。 2.结构形式 1.肯定句：主语+used to+动词原形 ·She used to play the piano every day.(她过去每天弹钢琴。一现在不每天弹了) ·They used to live in a small village.(他们过去住在小村庄里。一现在不住了) 2.否定句：主语+didn't use to+动词原形/主语+used not to+动词原形（后者较正式） 。He didn't use to like vegetables.(他过去不喜欢蔬菜。—现在可能喜欢了) ·I used not to get up early.(我过去不早起。一现在可能早起了) 3.疑问句：Did+主语+use to+动词原形？/Used+主语+to+动词原形？（后者较正式） 。Did you use to swim in the river when you were young?(你小时候常去河里游泳吗？) ·Used she to wear glasses?（她过去常戴眼镜吗？) 3.关键考点 1.无三单变化：used to中的used是固定结构，不受主语人称和数的影响，主语为第三人称单数时仍 用used to。 ·错误：She uses to walk to school.(正确：She used to walk to school.) 2.与一般现在时的区别：used to do强调“过去习惯，现在已改变”；一般现在时(often/usually+动词) 强调“现在的习惯”。 初一下沪教牛津版 【寒假专版】A版知识点全解 ·He used to drink coffee..(他过去喝咖啡。一现在不喝了) ●He often drinks coffee..(他现在常喝咖啡。) 3.疑问词提问：疑问词(What/Where/How)+did+主语+use to+动词原形？ ·What did they use to do on weekends?(他们过去周末常做什么？) 4.常见错误与纠正 1.错误：I am used to get up late.(混淆“used to do”与“be used to doing”,后者表示“习惯于做某事”) ●纠正：I used to get up late.(我过去常晚起。) 2.错误：Did he used to play football?(疑问句中used应还原为use) ●纠正：Did he use to play football? 知识点三：used to do&didn't use to 1.used to do(过去常常做某事) 1.基础用法：表示过去某个时间段内经常发生的动作或存在的状态，而现在不再如此。 2.例句： ·He used to play football after school..(他过去常常放学后踢足球。)→暗示现在可能不踢了。 ●My mother used to tell me stories before bed.(我妈妈过去常常在睡前给我讲故事。) ·They used to live in a small house.(他们过去住在一个小房子里。) 2.didn't use to(过去不常做某事) 1.基础用法：用于否定句，表示过去某个时间段内不经常发生的动作或不存在的状态，现在可能发生 了变化。 2.例句： 。She didn't use to like vegetables.(她过去不喜欢蔬菜。)→暗示现在可能喜欢了。 ·Idih't use to get up early..(我过去不常早起。) ·They didn't use to travel by plane.(他们过去不常坐飞机旅行。) 3.句式转换（疑问句与答语) 1.一般疑问句：Did+主语+use to do..? ·例句：Did you use to swim in the river?(你过去常常在河里游泳吗？) 。肯定回答：Yes,Idid.(是的，我常常。) 3 初一下沪教牛津版 【寒假专版】 A版知识点全解 。否定回答：No,I didn't.(不，我不常。) 2.特殊疑问句：疑问词+did+主语+use to do.? ·例句：Where did she use to live?(她过去住在哪里？)→she used to live in Beijing.(她过去住在 北京。) 考法精析 考法一：used to do与didn't use to的基本用法及句式转换 核心：掌握used to do表示“过去常常做某事（现在已不做）”和didn't use to表示“过去不常做某 事”的基本含义，以及肯定句、否定句、疑问句的正确结构 真题1（语法填空）： My grandfather(live)in this house,but now he lives with us in the city. 答案：used to live 解析：由“but now he lives with us in the city”可知，爷爷过去住在这所房子里，现在不住了，应用 used to do结构，live用原形。 真题2（单项选择）： -you-play computer games after school? A.Did use to B.Do use to C.Used to D.Are used to 答案：A 解析：根据句意“你过去放学后常玩电脑游戏吗？”可知，此句为used to do的一般疑问句，常用结 构为Did+主语+use to+动词原形，故选A。 考法二：used to do与didn't use to的句式转换及用法辨析 核心：掌握used to do的肯定句、否定句、疑问句转换规则，区分与现在情况的对比及常见错误用 法 真题1（句型转换)： He used to play basketball after school..(改为否定句) 答案：He didn't use to play basketball after school. 解析：used to do的否定句结构为“主语+didn't use to+动词原形”，故直接在used to前加didh't, used还原为use。 真题2（单项选择）： -shelive in Beijing?-No,she didn't. A.Did use to B.Used to C.Does use to 4 初一下沪教牛津版 【寒假专版】 A版知识点全解 D.Is used to 答案：A 解析：根据答句“No,she didn't.”可知问句为一般疑问句，used to do的一般疑问句结构为“Did+ 主语+use to+动词原形”，故选A。B选项为正式用法“Usd+主语+t0+动词原形”，但答句需 用“usedn't she”或“didn'tshe”,此处答句为“didn'tshe”,故A更符合；C选项时态错误；D选 项为“be used to doing”结构，表“习惯于”，与题意不符。 考法三：used to do与didn't use to的综合运用及句式转换 核心：掌握used to do的肯定、否定、疑问句式结构，区分与be used to doing的用法差异，并能结 合语境进行句式转换。 真题1（单项选择)： He_play basketball after school,but now he prefers football. A.uses to B.used to C.isused to D.was used to 答案：B 解析：根据“but now”可知此处表示过去的习惯，应用used to do结构，used to后接动词原形，A 选项uses to表述错误，C、D选项为be used to doing结构，意为“习惯于做某事”，不符合语境，故 选B。 真题2（语法填空）： -Did she_(use)to wear glasses? -No,she.But now she wears them every day. 答案：use;didn't 解析：第一空为一般疑问句，助动词Did后接动词原形use;第二空为否定回答，根据问句用Did 提问，否定回答用didn't。 解题小妙招 used to解题妙招 used to表过去，现在不做是关键； 肯定句中用原形，主语之后接used to: 否定疑问要注意，did提前use还原： 一般疑问did开头，否定句中didnt添： 语境对比是核心，but now来体现； 区分be used to doing,习惯用法记心间。 5 初一下沪教牛津版 【寒假专版】 A版知识点全解 真题演练 演练一：单项选择（共10题） 1.My mother_drink coffee,but now she likes it very much.
