It's time to / It's time for作用：提醒 “该做某事了”，不是报时间！不提问，直接陈述句提醒用途。 二、句型结构： 结构 例句 1. 问时间句型： -What time is it? -It's + 时间（数字 + o'clock / 几点几分） -What time is it?（几点了？） -It's seven o’clock.（七点。） 2. It's time to + 动词原形 It's time to get up.（到起床时间了。） 3. It's time for + 名词 / 课程 / 事物 It's time for English class.（到上英语课时间了。） 易错点提示 · 问时间： What time is it? (几点了？) 或 What’s the time? · 回答时间： It’s + 时间. (如：It’s seven o'clock.) · 到做某事的时间了： · It’s time to + 动词原形 (to后面跟动作) · 例句：It’s time to get up. · It’s time for + 名词 (for后面跟事物/课程) · 例句：It’s time for music class. 经典例题 单项选择： -It’s 7:00 a.m. It’s time _______. A. for get up B. to get up C. for up 点拨 答案：B 【解析】句意：上午7点了。该起床了。 “get up” 是一个动词短语（起床），表示动作。在 “It’s time...” 句型中，后面跟动词要用 “to”，所以是 “It’s time to get up”。选项 A 和 C 结构错误。 小练笔 01 选词填空 (to / for)。 1. It’s 6:30. It’s time ________ get up, my boy. 2. It’s 12:00. It’s time ________ lunch. 3. It’s 8:00. It’s time ________ go to school. 4. It’s 1:20. It’s time ________ music class. 5. It’s 10:00. It’s time ________ bed. 时间介词 at 的用法高频易错点02 一、概念： at 专门用在：具体、精准的时间点前面中文理解：在……（几点整 / 某个时刻）口诀：小时间、精准点，前面就要用 at。 二、句型结构： 结构 例句 人 + 动作 + at + 具体时间 We have lunch at twelve o’clock.（我们在十二点吃午饭。） 易错点提示 在英语中，表示“在几点钟”或“在某个具体的时刻”，我们使用介词 at。 经典例题 I have breakfast _______ 7:15 in the morning. A. in B. on C. at 点拨 答案： C 【解析】句意：我在早上7:15吃早饭。 “7:15” 是一个具体的时间点。在英语中，具体时间点前面要用介词 “at”。“in” 用在早上/下午/晚上（in the morning），“on” 用在星期几或具体某一天。 小练笔 02 选择正确的介词填空 (at, in, on)。 1. I go to the art class ________ four forty. 2. What time do you go to school ________ the morning? 3. We have a birthday party ________ Sunday. 4. Let’s go to the gift shop ________ ten to twelve. 5. I play basketball ________ 3:30 every Friday. 时间的两种表达法（顺读法与逆读法）高频易错点03 一、概念： 1. 顺读法（最简单、最常用）概念：先读小时，再读分钟，顺着钟表数字依次读。适合：所有时间，零基础首选。 2. 逆读法（英式常用、考试必考）概念：先读分钟，再读小时，倒着读；要用 past /to 二、句型结构： 结构 例句 顺读法：小时 + 分钟 7:20 → seven twenty 逆读法：1. 分钟 + past + 小时 7:10 → ten past seven 逆读法：2. (60−分钟) + to + (小时 + 1) 4:40 → twenty to five 逆读法：3. 特殊半点：30 分钟 = half 7:30 → half past seven 易错点提示 · 顺读法 (直接读)： 先说“几点”，再说“几分”。 (如：7:15 → seven fifteen) · 逆读法 (借助介词)： · ≤30分钟：用 past，表示“几点过几分”。 (如：7:15 → a quarter past seven / fifteen past seven) · ＞30分钟：用 to，表示“差几分到几点”。 (如：11:50 → ten to twelve，注意：几点要+1) · 特殊：30分钟用 half past。 (如：7:30 → half past seven) · 本单元重点例句：It’s ten to twelve. (11:50) 经典例题 It’s 8:40. We can also say (也可以说) it’s _______. A. twenty to nine B. twenty past eight C. forty past eight 点拨 答案：A 【解析】句意：8:40了。我们也可以说还有20分钟到9点。8:40 超过30分钟了，要用 “to”。离下一个小时（9点）还差20分钟，所以是 “twenty to nine”。选项 B 是 “8:20”，选项 C 的表达方式是错的（past 不能用于超过30分钟）。 小练笔 03 写出下列时间的另一种英文表达。 1. 7:15 → seven fifteen → _______________ 2. 3:45 → three forty-five → _______________ 3. 12:00 → twelve o’clock → _______________ 4. 4:30 → four thirty → _______________ 5. 2:50 → two fifty → _______________ 综合训练 一、单项选择。 ( ) 1. —What time is it? —It’s _______.
