数字 20–100 和时间
数字 20–100；What time is it? It's ...；a.m. / p.m.、morning / afternoon / evening；发音 /eɪ/ /aɪ/ /ɔɪ/；VOA Lesson 8 对话。
🗣️ 发音
今天开始练双元音：从第一个音滑到第二个音，前重后轻（各大声读 3 遍）：
| 音标 | 怎么发 | 例词 |
|---|---|---|
| /eɪ/ | 从 /e/ 滑到 /ɪ/（像「诶-」） | eight, eighty, day, today, later, a.m. 的 a |
| /aɪ/ | 从「啊」滑到 /ɪ/（像「爱」） | time, five, nine, my, night, I'm |
| /ɔɪ/ | 从 /ɔː/ 滑到 /ɪ/（像「奥伊」） | boy, toy, enjoy, noisy |
对比：late /leɪt/ vs light /laɪt/；bay /beɪ/ vs buy /baɪ/ vs boy /bɔɪ/。
⚠️ eight 别读成「诶特」两拍，是一个滑动的音 /eɪt/。
📐 语法
① 数字 20–100
- 整十：twenty 20, thirty 30, forty 40（没有 u！）, fifty 50, sixty 60, seventy 70, eighty 80, ninety 90, one hundred 100
- 中间加横线：21 twenty-one，35 thirty-five，99 ninety-nine
- ⚠️ 重音区分：thirteen 13（重音在后） vs thirty 30（重音在前）；fourteen/forty、fifteen/fifty 同理
② 问时间、说时间
| 问 | 答 | 读法 |
|---|---|---|
| What time is it? | It's 7:00. | seven o'clock |
| It's 7:15. | seven fifteen | |
| It's 7:30. | seven thirty | |
| It's 7:45. | seven forty-five | |
| What time is your class? | It's at 8 p.m. | 用 at + 时间 |
- a.m. 上午（午夜到中午），p.m. 下午和晚上
- 也可以说时段：in the morning / in the afternoon / in the evening，但 at night
- 先学最简单的「数字直读法」（7:15 = seven fifteen），a quarter past 之类以后再学
③ 本课对话里的问句：Are you busy? → Yes, I'm busy. / I'm a little busy.（be 动词问句复习）
