Part 03 Language points Language points 祈使句 结构：动词原形 + 宾语/状语（省略主语 You）。 作用：表示命令、建议、提醒。 文中例句：Use air conditioners less. Walk more and drive less. Bring our own bags... Recycle bottles and boxes. 注意：标题的 Follow the "3R" rules 也是祈使句。 Language points 定式（to do）作目的状语 结构：Follow the rules to save energy...（做A事，为了达成B事） 解析：句首的 Follow... 是主要动作，后面的 to save... 用来解释“为什么要遵循这些规则”。这里的 to 表示目的，后面必须接动词原形 save。 Let's 句型（表示建议） 原文：Let's follow the "3R" rules.（让我们遵循3R规则吧。） 解析：Let's 是 Let us 的缩写，后面接动词原形（follow）。它和祈使句很像，但包含了说话者自己（我们），语气更亲切，表示“咱们一起做……吧”。 Language points： less vs fewer 副词（less vs fewer）修饰动词 less（更少地）和 more（更多地）在这里是副词，用来修饰前面的动词，而不是修饰名词。 文中例句：Use air conditioners less.（修饰 Use，表示“少用”） Walk more.（修饰 Walk，表示“多走路”） drive less.（修饰 drive，表示“少开车”） 对比：如果后面接名词，比如 less water，那它就是形容词；但这里是修饰动作， 所以是副词。 并列结构：Walk more and drive less 使用 and 连接两个并列的祈 使句，形成对比（多...少...）。 Language points less + 不可数名词 Use less water. (water 不可数) Use less electricity. (electricity 不可数) fewer + 可数名词(复数) Use fewer resources.(resources 可数复数) Buy fewer things.(things 可数复数) less water(不可数) fewer resources (可数复数) fewer water(不可数，错误) less resources (可数复数，错误) Language points 主谓一致（第三人称单数 -s） 原文：... every little thing helps!（每一件小事都有帮助！） 解析：主语是 every little thing（每一件小事），属于第三人称单数，且描述的是客观事实（一般现在时），所以动词 help 要加 -s 变成 helps。 名词单复数 名词复数：rules（规则），air conditioners（空调），bags（包），shops/markets（商店/市场），bottles/boxes/clothes/toys/books。这些都表示类别，所以用复数形式。 开始\暂停 Exercise 根据首字母提示补全单词 We should s______ energy to protect our Earth.
