Unit 6 Getting along with others 单元语法专项-2026-2027学年上学期英语五年级上册（译林版三起新教材） 第一部分 单元核心语法知识点总结 一、提建议句型：Why don't...? / Why not...?（单元核心语法★★★） 1. 基本概念 Why don't...? 和 Why not...? 都用来向别人提出建议，意为"为什么不……呢？"，语气友好委婉，是本单元最重要的交际语法。 2. Why don't + 主语 + 动词原形？ - 结构：Why don't + 主语（you/we/they）+ 动词原形 + 其他？ - 针对不同对象： - Why don't we...? 我们为什么不……呢？（提议一起做） - Why don't you...? 你为什么不……呢？（建议对方做） 例：Why don't we write a letter to Zhang Ying? 我们为什么不给张英写封信呢？ 例：Why don't you say sorry to your deskmate? 你为什么不向你的同桌道歉呢？ 3. Why not + 动词原形？ - 结构：Why not + 动词原形 + 其他？ - 这是 Why don't you/we...? 的简略形式，省略了主语和助动词的部分，意思完全相同，可以互换。 例：Why not move our wall back three chi? 为什么不把我们的墙往后退三尺呢？ = Why don't we move our wall back three chi? 4. 常见回应方式 - 肯定回应（赞同建议）：Good idea! / That's a good idea! / Great! / Sure! / OK! - 委婉拒绝：Sorry, I can't. / I'm afraid not. / That sounds great, but... 5. 拓展：其他提建议句型（了解） 句型 含义 后接形式 Let's... 让我们…… 吧 动词原形 What about...? …… 怎么样？ 动词 - ing How about...? …… 怎么样？ 动词 - ing Shall we...? 我们…… 好吗？ 动词原形 二、祈使句：Let 的用法（单元重点语法★★） 1. 基本概念 let 引导的祈使句用来表示建议、请求或命令，意为"让……做……吧"。 2. Let sb do sth 结构 - 结构：Let + 宾语（人称代词用宾格）+ 动词原形 + 其他 - let 后必须接动词原形，不能加 to 例：Let me take your bag. 让我来帮你拿包吧。 例：Let's work together. 让我们一起努力吧。 ⚠️ 注意：Let's = Let us，意为"让我们"，包含说话人和听话人双方。 3. 否定形式 - Let sb not do sth 让某人不要做某事 例：Let's not waste time. 我们不要浪费时间了。 4. 常见回应 - 赞同：Good idea! / Great! / OK! / All right! - 委婉拒绝：Sorry, I... 三、单元语法高频考点&易错点总结 易错点 错误示例 正确用法 Why not 后接动词形式错误 Why not to go now? Why not 后必须接动词原形，不能加 to Why don't 后遗漏主语 Why don't go now? Why don't 后必须接主语（you/we/they），再加动词原形 let 后接动词形式错误 Let me to help you. let 后必须接动词原形，不能加 to let 后人称代词形式错误 Let I help you. let 后接人称代词宾格（me/us/him/her/them） advice 可数性误用 some advices advice 是不可数名词，"一条建议" 用 a piece of advice 建议句型回应混淆 —Why not go? —Yes, I do. 回应建议用 Good idea! / Great! 等，不用 Yes/No 回答 四、单元语法问答背诵模板 1. 提出建议并回应 A: Why don't we have a picnic in the park?
