Unit 8 Time 核心语法（专项训练）- 2025-2026学年北师大版（三起）（2012）英语五年级下册

北师大版英语五年级下册 Unit 8 Time 核心语法专项提优 单元语法梳理 本单元的核心语法是时间表达法，主要围绕"询问时间"和"说明时间"两大功能展开。具体包括以下内容： 一、整点时间表达法 整点时间用"数字 + o'clock"表示，其中o'clock可以省略。 例如：seven o'clock（七点整），eight o'clock（八点整）。 询问整点时间用"What time is it?"，回答用"It's... o'clock." 二、非整点时间表达法 非整点时间有两种表达方式： 直接读法：先说小时数，再说分钟数。 例如：six thirty（六点三十分），eight forty-five（八点四十五分），nine fifteen（九点十五分）。这是最常用的表达方式，简单直接。 逆读法（half past/quarter past/to）：当分钟数为30时，可用"half past + 小时"；当分钟数为15时，可用"quarter past + 小时"；当分钟数为45时，可用"quarter to + 下一个小时"。 例如：half past eight（八点半），quarter past nine（九点一刻），quarter to ten（九点四十五分/差一刻十点）。 三、It's time to... 句型 该句型用于表达"该做某事了"，后面跟动词原形。 例如：It's time to get up.（该起床了。）It's time to go to school.（该上学了。） 四、日常活动时间询问与回答 询问日常活动的时间安排，使用"What time do you...?"句型。回答时用"I... at..."结构。需要注意的是，当主语是第三人称单数（he/she）时，动词要加-s或-es 例如：What time does he get up? He gets up at seven. 五、相关词汇 本单元的核心词汇包括：o'clock（……点钟），early（早的），late（晚的），hurry（赶紧），fix（修理），slow（慢的），broken（坏的），time（时间），watch（手表）。 核心语法专项练习 一、用英语写出下列钟表显示的时间。 1. 7:00 → ____________________2. 8:30 → ____________________ 3. 9:15 → ____________________4. 10:45 → _________________ 5. 11:20 → __________________6. 4:05 → ____________________ 7. 5:50 → ___________________8. 2:40 → ____________________ 9. 12:00 → __________________10. 3:35 → ____________________ 二、根据句意和首字母提示补全单词，完成句子。 1.
