译林版英语六年级上册 Unit 5 Keeping it clean 语法专项 （情态动词 should / shouldn't 用法） 易错总结： - should / shouldn't 后接动词原形，不加 -s 或 -ing。 - 变一般疑问句时，将 should 提到主语前。 - 否定形式 shouldn't 表示“不应该”，用于劝阻不环保的行为。 -回答Should...? 问句时，用 Yes, 主语+ should. / No, 主语+ shouldn't. 第一部分：核心语法梳理 本单元围绕“保持环境整洁”主题展开，核心语法是情态动词 should和shouldn't的用法，用于提出建议、倡导环保行为。 情态动词 should / shouldn't 用法详解 1. 基本概念 should 是情态动词，意为“应该”，用于表示建议、责任、义务或期望。shouldn't 是 should not 的缩写形式，意为“不应该”，用于表示劝阻或禁止做某事。 2.句型结构 肯定句：主语 + should + 动词原形 + 其他. - We should keep our school clean. 我们应该保持学校整洁。 - You should put rubbish in the bin. 你应该把垃圾放进垃圾桶里。 否定句：主语 + shouldn't + 动词原形 + 其他. - We **shouldn't** litter in the park. 我们不应该在公园里乱扔垃圾。 - You shouldn't waste water. 你不应该浪费水。 一般疑问句：Should + 主语 + 动词原形 + 其他? - Should we plant more trees? 我们应该种更多的树吗？ - 肯定回答：Yes, 主语 + should. - 否定回答：No, 主语 + shouldn't. 3.用法要点 should 没有人称和数的变化，所有主语（I/you/he/she/we/they）后都用 should，不加 -s。 should 是情态动词，后接动词原形，不能说 should goes 或 should playing。 shouldn't 也后接动词原形，没有 shouldn't to 的说法。 should 的语气比 must（必须）要弱，更多用于“提建议”而非“强制命令”。在环保话题中，should 用来表达“每个人都应尽的责任”。 4.本单元常见搭配 - keep + 宾语 + 形容词：keep our city clean / keep the air fresh - put + 名词 + in/into + 地点**：put rubbish in the bin - plant + 名词：plant more trees / plant flowers - reuse / recycle 相关表达：We should reuse plastic bags. / We should recycle waste paper. 第二部分：对应练习 练习一：用 should 或 shouldn't 填空（10分） 1.
