2025-2026学年译林版七年级英语下册期中复习讲义 祈使句 & 建议句型 (Let's, Why not...)

译林版·七年级英语下册期中复习 ——祈使句 & 建议句型 (Let's, Why not...) 祈使句用于表达命令、请求、劝告、警告、禁止等，建议句型用于提出自己的看法或提议。译林版七下Unit 4《Finding your way》和Unit 2《Neighbours》中均有涉及。期中考试常以单选、补全对话和句型转换形式考查。本讲系统梳理祈使句的构成与用法，以及常见建议句型的结构与回答，并通过分层练习确保学生灵活运用。 一、祈使句的基本用法 祈使句通常省略主语 you，以动词原形开头，表示命令、请求、建议或禁止。否定形式在动词原形前加 Don't。 类型 结构 例句 肯定祈使句 动词原形 + 其他. Open the door, please. / Sit down. 否定祈使句 Don't + 动词原形 + 其他. 以Let's开头的祈使句 Let's + 动词原形 + 其他. 📌 注意：Let's 包括说话者和听话者双方；Let us 不包括听话者（请求对方允许）。初中阶段主要掌握 Let's 的用法。 二、祈使句的回答 肯定祈使句的回答常用：OK. / All right. / Yes, I will. / Sure. 否定祈使句的回答常用：Sorry, I won't. / OK, I won't. 三、提建议的常用句型 向对方提出建议时，常用以下句型，语气礼貌且友好： 句型 结构 例句 肯定回答 Let's开头的建议 Let's + 动词原形. Let's watch a movie. Good idea. / That sounds great. Why not / Why don't you Why not + 动词原形? Why don't you + 动词原形? Why not go swimming? Why don't you try again? Good idea. / That's a good suggestion.

That sounds nice. / I'd love to. Would you like to Would you like to + 动词原形? Would you like to join us? Yes, I'd love to. / I'd like to, but... 四、祈使句与建议句型的转换 同一建议可以用不同句型表达。例如： Let's play football. = Why not play football? = Shall we play football? = What about playing football? 五、易错点与温馨提示 常见错误： • 误：Let's to go home. 正：Let's go home. (Let's后接动词原形) • 误：Why not to have a rest? 正：Why not have a rest? (Why not后接动词原形) • 误：What about go shopping? 正：What about going shopping? (about是介词，后接动名词) • 误：Shall we to leave now? 正：Shall we leave now? (Shall we后接动词原形) • 注意：回答建议时，肯定回答要热情，否定回答要委婉并说明理由。 典型例题（答案与题目已逐题核对） 1. (单选) — Let's go to the zoo this Sunday. — ________. A.
