Unit 1 单元语法精讲精练2026-2027学年人教版九年级英语上册

九上 Unit 1 单元语法精讲精练 单元两大核心语法 语法一：used to 表过去的习惯 / 过去存在的状态 一、核心含义 used to + 动词原形 表示：过去常常做某事 / 过去曾经存在某种状态（暗含：现在已经不这样了，专门用于今昔对比） 二、句式结构 肯定句：主语 + used to + 动词原形 例：I used to walk to school. 我过去常常走路去上学。 否定句两种写法 ① 主语 + didn’t use to + 动词原形 ② 主语 + used not to + 动词原形 例：She didn’t use to live in a small house. = She used not to live in a small house. 一般疑问句两种写法 ① Did + 主语 + use to + 动词原形？ ② Used + 主语 + to + 动词原形？ 例：Did they use to take old trains? = Used they to take old trains? 特殊疑问句：特殊疑问词 + did + 主语 + use to do…? 例：Where did you use to shop? 你以前去哪里购物？ 三、易混辨析 used to do 过去常常做（现在不做） be used to doing 习惯于做某事（to 是介词，后加动名词） be used to do /be used for doing 被用来做某事（被动语态） 例句对比： I used to live in the countryside.（过去住乡下） I am used to living in the city now.（现在习惯住城市） Wood is used to make paper.（木头被用来造纸） 四、标志词 in the past、before、ten years ago、when I was young、formerly 语法二：现在完成时（have/has + 过去分词） 本单元搭配 used to 对比使用，描述从过去持续到现在、对现在造成影响的变化，中考必考时态 1. 核心用法 ① 过去发生的动作，结果持续到现在（有影响） They have built a new hospital. 他们建了新医院（现在医院存在） ② 动作从过去开始，持续到现在，常搭配 for/since We have lived here for 20 years. 2. 标志词 already、yet、ever、never、just、recently、so far、for + 时间段、since + 时间点 3. 句型结构 肯定：主语 + have/has + 过去分词 否定：主语 + haven’t/hasn’t + 过去分词 疑问：Have/Has + 主语 + 过去分词？ ⚠️ 考点：yet 只用在否定 / 疑问；already 多用于肯定句 4. 现在完成时 vs 一般过去时（单元重难点） 一般过去时： 只讲过去动作，和现在无关，带明确过去时间词 (yesterday/last year) They built the road last year.（去年修的，只陈述过去） 现在完成时：强调对现在的影响，无具体过去时间 They have built the road.（路现在有了） 语法三：不定代词 someone/anyone/everyone/nothing/everything 形容词后置：everything important ✅；important everything ❌ 否定转换：nothing = not anything；no one = not anyone everyone 作主语，谓语动词用单数 Everyone likes the new library. 第二部分 语法专项精练 一、used to 基础专练（用所给词适当形式填空） 1.
