寒假预习：专题06 Unit 3 Time for school语法讲义+知识演练 2025-2026学年四年级下册英语（人教版） 核心语法点梳理 （一）It's time to/for 表达“该做某事了”（核心语法） 1. 结构一：It's time for + 名词（三餐、课程、场所等），后接名词或名词短语。 课本例句：It's time for breakfast.（该吃早餐了。） It's time for English class.（该上英语课了。） 2. 结构二：It's time to + 动词原形，后接具体动作。 课本例句：It's time to get up.（该起床了。） It's time to go to school.（该去上学了。） 3. 转换规律：两者可同义转换，如 It's time for lunch. = It's time to have lunch.（该吃午餐了。） （二）What time 引导的特殊疑问句（询问时间） 1. 基本结构：What time is it?（现在几点了？），可加 now 强调“此刻”，即 What time is it now? 课本例句：— What time is it now? — It's 5 o'clock.（—现在几点了？—现在五点了。） 2. 答语：（1）整点：It's + 数字 + o'clock.（o'clock 可省略），如 It's 3 o'clock.（三点了。） （2）非整点：It's + 数字:数字，如 It's 8:30.（八点半了。） 3. 用法提示：仅用于询问具体时间，不用于询问日期。 （三）时刻表达法（整点与非整点） 1. 整点表达：数字 + o'clock（o'clock 仅用于整点，可省略），课本核心表达。 例句：It's 9 o'clock.（九点了。） It's 12 o'clock.（十二点了。） 2. 非整点表达（四年级重点）：直接用“数字:数字”表示，分钟在前、小时在后，无需额外词汇。 课本例句：It's 7:10.（七点十分。） It's 4:50.（四点五十分。） 3. 注意：四年级暂不涉及“分钟 + past/to”表达，仅掌握直接表达法即可。 （四）情景祈使句（时间相关提醒、催促与祝福） 1. 催促类：Hurry up!（快点！）/ Just a minute.（等一下。），无主语，语气直接。 课本例句：Hurry up! It's time for class.（快点！该上课了。） 2. 提醒类：Time to + 动词原形.（省略 It's，更口语化），课本常用表达。 例句：Time to go home, kids.（孩子们，该回家了。） 3. 祝福类：Have a nice day!（祝你一天愉快！），用于告别时表达祝福。 课本例句：— Bye, Mum. （再见，妈妈。） — Bye. Have a nice day!（再见。祝你一天愉快！） 知识演练 一：用 to/for 填空（每空一词） 1. It's time ______ breakfast. Let's eat some bread. 2. It's 7:00 a.m. It's time ______ get up. 3. It's time ______ English class.
