Unit4 语法专练 -2025-2026学年外研版七年级英语下册

外研版7下第四单元语法专练 祈使句 第一部分：祈使句知识点梳理 一、什么是祈使句？ 祈使句用于表达命令、请求、建议、警告、禁止等。它的特点是通常以动词原形开头，主语"you"通常省略，句末用句号或感叹号。 二、祈使句的四种基本形式 肯定祈使句：直接用动词原形开头。 例如：Sit down. / Open the door. / Listen to me carefully. 否定祈使句：在动词原形前加Don't。 例如：Don't be late. / Don't play in the street. / Don't forget to call me. 强调祈使句：在动词原形前加Do，表示"务必"、"一定要"。 例如：Do be careful! / Do come to my party. / Do tell me the truth. Let型祈使句：用"Let + 宾语 + 动词原形"结构。 例如：Let's go. / Let him try again. / Let me help you. 三、祈使句的重要考点 1. Please的位置 Please可以放在句首或句尾，放在句尾时通常加逗号。 例如：Please open the window. / Open the window, please. 2. Let's 与 Let us 的区别 Let's（包括说话对象在内）：咱们一起…… 反意疑问句用"shall we?" 例如：Let's go for a walk, shall we? Let us（不包括说话对象）：您让我们……（请求对方允许） 反意疑问句用"will you?" 例如：Let us have a rest, will you? 3. "祈使句 + and/or + 陈述句"句型 这个结构相当于条件句。 and表示"如果……就会……"（顺承关系） 例如：Hurry up, and you will catch the bus. = If you hurry up, you will catch the bus. 例如：Work hard, and you will succeed. or表示"否则"（转折/警告关系） 例如：Hurry up, or you will miss the bus. = If you don't hurry up, you will miss the bus. 例如：Put on your coat, or you'll catch a cold. 4. 带有主语的祈使句 有时为了指明对象或表达强烈情绪，可以保留主语you。 例如：You be quiet!（你给我安静点！） 例如：Everybody listen, please.（请大家听我说。） 5. 祈使句的反意疑问句 肯定祈使句的反意疑问句通常用"will you?"（表请求）或"won't you?"（表邀请） 例如：Open the door, will you? 例如：Have a cup of tea, won't you? 否定祈使句的反意疑问句只能用"will you?" 例如：Don't be late, will you? 第二部分：祈使句专项练习题 一、单项选择（共10题） 1. ______ quiet in the library.
