2026新版九年级上册人教版英语Unit 1 The Changing World 【语法精讲精练】一般过去时和现在完成时区别 一、一般过去时 vs 现在完成时 区分讲解 1. 核心含义 一般过去时：单纯描述发生在过去某一个固定时间点的动作、存在的状态，这件事和当下没有任何关联； 现在完成时：描述始于过去的行为，该行为对当下产生了对应的结果、影响，或是动作从过去一直持续到如今。 时态 核心含义 标志性时间词 全新例句 一般过去时 只陈述过去发生的事，与现在无关 yesterday、last month、in 2010、…ago My grandpa built a small greenhouse thirty years ago. 现在完成时 过去动作留下当下影响 / 持续到现在 already、yet、ever、never、for + 时长、since + 过去时间 We have lived in this new flat for ten years! 2. 基础句式结构 一般过去时：主语 + 动词过去式 + 剩余句子成分 例句：She planted lots of fruit trees on the farm last spring. 现在完成时：主语 + have / has + 动词过去分词 + 剩余句子成分 例句：She has planted hundreds of fruit trees since 2018. 3. 高频考试重难点 (1)一般过去时必须搭配清晰、具体的过去时间词；现在完成时绝对不能搭配明确的过去时间点。 (2)两种时态侧重点完全不同：现在完成时重在体现当下的影响、持续时长；一般过去时只客观复述过去发生过的一件事。 (3)already 仅用于肯定陈述句；yet 只用在否定句、疑问句末尾。 4. 拓展补充 (1). 现在完成时可用来描述人生过往的经历：I have travelled to many western countries.（我去过很多西方国家旅行） (2). 一般过去时常搭配 used to 连用，描述过去的旧状态：He used to work as a lorry driver. 二、used to 固定句型详解 1. 基础用法 表示“过去经常性、习惯性做某事，如今已经不再这样了”，to 的后面只能接动词原形。 2. 三类句式结构汇总 句式类型 完整结构 全新例句 肯定句 主语 + used to + 动词原形 This piece of land used to be full of bushes and dirt. 否定句 主语 + didn’t use to + 动词原形 / 主语 + used not to + 动词原形 Villagers didn’t use to have convenient e-payment years ago. 一般疑问句 Did + 主语 + use to + 动词原形？ Did you use to walk on the narrow track to school? 3. 易混核心考点 (1). `used to do` 和 `be used to doing` 辨析： `used to do` 含义：过去常常（现在不再）； `be used to doing` 含义：习惯于做某事。 (2). used to 和 would 的区别：would 后面只能搭配动作类动词，不能搭配 be / have / like 这类表状态的词汇。 专项练习 一、用所给动词的正确形式填空（每题2分，共30分） 1.
