寒假预习：专题10 Unit 5 What time is it?语法讲义+知识演练 2025-2026学年三年级下册英语（外研版） （一）核心语法点1：时间表达法 1. 整点表达 结构：It's + 数字 + o'clock. （o'clock可省略） 例句：It's seven o'clock. （现在七点钟。） It's nine o'clock. （现在九点钟。） It's six o'clock in the morning. （现在早上六点钟。） 2. 半点表达 结构：It's half past + 数字. （half past 表示“……点半”，数字对应整点） 例句： It's half past six. （现在六点半。） It's half past eight. （现在八点半。） It's half past seven. It's time for school. （现在七点半了，该去上学了。） 3. 注意：：fifteen past...（……点十五）、forty-five past...（……点四十五） （二）核心语法点2：询问时间的特殊疑问句及回答 1. 核心句型（课本原句，最常用） —What time is it? （现在几点了？） —It's ... o'clock. / It's half past .... （……点钟了。/ ……点半了。） 2. 课本例句（原句）： —What time is it? —It's seven o'clock. （——现在几点了？——七点钟了。） —What time is it? —It's only six o'clock. （——现在几点了？——才六点钟。） （三）核心语法点3：提醒做某事句型（It's time to / for ...） 1. 两种句型 句型1：It's time to + 动词原形. （to后面接“做某事”的动作，即动词） 句型2：It's time for + 名词. （for后面接“某事/某物”，即名词） 例句： It's time to get up. （该起床了。to + 动词原形） It's time for school. （该去上学了。for + 名词） It's time to do your homework. （该做家庭作业了。to + 动词短语） It's time for dinner. （该吃晚饭了。for + 名词） （四）核心语法点4：一般现在时第三人称单数 1. 适用场景：主语是he、she、it或单数人名/称呼时，谓语动词要变“第三人称单数形式”。 2. 本单元重点动词变化： need → needs （需要） 例句：She needs to do her homework now. （她现在需要做家庭作业。） call → calls （打电话） 例句：My mum calls my dad every evening. （我妈妈每天晚上给我爸爸打电话。） 知识演练 一、时间表达专项填空 1.
