讲述过去的事
能完整地讲述过去的事：会提问，会作否定回答，会说出动词的第三种形式。
标注的核心时长。核心模块中有两项未标注时长，因此实际课时比总和更长。
语法
5 分钟在 A1，过去时只用于肯定句。现在要学全部形式。
疑问句和否定句用助动词 did 构成，这时实义动词要回到原形。
| 肯定句 | I worked at home. / I went to Italy. |
| 疑问句 | Did you work at home? / Did you go to Italy? / What did you do? |
| 否定句 | I didn't work. / I didn't go. |
| 简略回答 | Yes, I did. / No, I didn't. |
这和一般现在时是同一个道理（A1 第8–9课）：词尾转移到助动词上，实义动词保持原形。 Did 用于所有人称——不加 -s，也没有例外。
动词的第三种形式（过去分词）。 英语动词有三种形式，第三种从下几课起就要用到：
| 原形 | 过去式 | 第三种形式 |
|---|---|---|
| work | worked | worked |
| go | went | gone |
| see | saw | seen |
| do | did | done |
| have | had | had |
| take | took | taken |
| give | gave | given |
| write | wrote | written |
| speak | spoke | spoken |
| eat | ate | eaten |
| drink | drank | drunk |
| be | was/were | been |
规则动词的第二种和第三种形式相同：worked — worked。不规则动词的第三种形式要单独记—— 现在完成时（第3课）和被动语态（第19课）用的正是这种形式。
中文母语者的常见错误
已针对你的语言编写过去时表示了两次。
✗ Did you worked?
✗ I didn't went
✓ Did you work?
， I didn't go。刚在 A1 学会“说过去的事，动词要变”，就很想处处都变。可是过去已经由 did 表示了，后面的动词只能用原形。这是本级最常见的错误。
疑问句不用 did。
✗ You went to Italy?
✗ What you did in the evening?
✓ Did you go to Italy?
，What did you do in the evening? 和 A1 第8课的 do 一样：汉语只加“吗”、换上“什么”，语序不变。英语的疑问句需要 did，有疑问词时 did 紧跟在它后面。
把 not 当作“没”。
✗ I not went to work
✓ I didn't go to work
。 “我没去上班”的“没”直接放在动词前面，于是 not 也被放到动词前。英语的否定要用 didn't，后面接动词原形。
发音
3 分钟didn't 在快速的口语中会丢掉 t： /ˈdɪdnt/ → /ˈdɪdn/。在辅音前，t 几乎总是消失： I didn't know 听起来像 /aɪ ˈdɪdn nəʊ/。
疑问句里的 did 不重读——读 /dɪd/，甚至只剩 /d/：Did you go? → 大致是 /dju ˈɡəʊ/。重音落在实义动词上。

写作
写五个句子，讲讲你上个周末，其中至少有一个否定句，还要向对方提一个问题。
范例： Last weekend I went to my sister's house. I took the train because I don't drive. We cooked dinner and watched a film. I didn't work at all. Did you have a good weekend?
检查清单：did 和 didn't 后面的动词是原形吗？疑问句里有 did 吗？
