核心规则（Grammar Core）
什么时候用？
- 过去某个时刻正在进行 — At 8 p.m. last night, I was watching TV.
- 背景描写（故事中的场景铺设） — The sun was shining and the birds were singing.
- 被打断的动作 — I was reading when the phone rang.
构成公式
| 句型 | 公式 | 例句 |
|---|---|---|
| 肯定 | S + was/were + V-ing | She was sleeping at midnight. |
| They were playing football at 5 p.m. | ||
| 否定 | S + was/were + not + V-ing | They weren’t listening to the teacher. |
| I wasn’t watching TV when you called. | ||
| 疑问 | Was/Were + S + V-ing? | Were you waiting for me? |
| Was he studying when you arrived? |
was → I / he / she / it were → you / we / they

时间轴定位
过去 ←————————— 现在 ——————————→ 将来
▶━━━━━━◀ ↕
过去某段时间 现在
"I was reading at 9 p.m."
把现在进行时的”摄像机”搬到过去——过去进行时就是过去某个时刻正在播放的视频。
核心句式：when + while ⚠️（KET/PET 高频）
when + 短动作（过去时）, 长动作（过去进行时）
I was walking home when it started to rain.
━━━━━━━━━━━━━━ ✕
长动作（进行时） 短动作打断（过去时）
while + 长动作（过去进行时）, 长动作（过去进行时）
While I was cooking, my brother was doing his homework.
━━━━━━━━━━━━ ━━━━━━━━━━━━━━━━━━━━━
两个长动作同时进行
口诀：when 后面跟短动作（砰！的一下），while 后面跟长动作（一直在做）。
对比辨析：过去进行时 vs 一般过去时
| 过去进行时 | 一般过去时 |
|---|---|
| 强调正在进行的过程 | 强调完成的动作 |
| I was reading a book at 10 p.m. | I read a book last night. |
| （10点那个时刻正在读，不知道读没读完） | （读了，可能读完了） |
😂 Grammar Joke
完美的不在场证明
Detective: “Where were you last night at 10 p.m.?” Suspect: “I was watching TV.” Detective: “What were you watching?” Suspect: “I was watching… the window. From outside your house.” Detective: ”…”
侦探问嫌疑人昨晚10点在做什么（过去进行时 = 过去某个时刻正在做的事）。 嫌疑人说”我正在看电视”——完美的不在场证明。 侦探追问”你正在看什么？” 嫌疑人说”我正在看……窗户。从你家外面。”
语法点：was/were doing 用于描述过去某个精确时刻正在进行的动作——这正是侦探询问不在场证明的标准句式。书虫《Sherlock Holmes》里充满了 “What were you doing at…?”
🏛 语言文化光点
侦探小说最爱的时态
阿加莎·克里斯蒂（Agatha Christie）和柯南·道尔（Conan Doyle）的侦探小说中，过去进行时出现频率极高。为什么？因为侦探需要问每个嫌疑人：“What were you doing at 9 o’clock last night?”（昨晚9点你在做什么？）
书虫系列里的《Sherlock Holmes》就充满了这种句式。当 Holmes 询问证人时，证人总是用过去进行时描述案发时的场景：
“I was sitting in my room. I was reading the newspaper. Suddenly I heard a scream.”
先用过去进行时铺设背景，再用一般过去时描述突发事件——这是英语叙事的经典节奏。
例题精讲
例1（📘 KET · when 句式）
I _____ (walk) to school when I _____ (see) a beautiful rainbow.
答案：was walking, saw。走路 = 长动作 → 进行时；看见彩虹 = 短动作 → 过去时。
例2（📘 KET · while 句式）
While Tom _____ (play) the guitar, his sister _____ (dance).
答案：was playing, was dancing。两个长动作同时进行 → 都用进行时。
例3（📘 KET · 场景判断）
At 7 o’clock yesterday evening, we _____ (have) dinner.
答案：were having。at 7 o’clock = 过去某个时刻正在 → 进行时。
例4（📙 PET · 叙事段落）
Last Saturday, I went to the park. The sun (1)_____ (shine) and children (2)_____ (play) on the swings. I (3)_____ (sit) on a bench when suddenly a dog (4)_____ (run) towards me.
答案：(1) was shining (2) were playing (3) was sitting (4) ran 前三个铺设背景（进行时），第四个是突发事件（过去时）。
例5（📙 PET · 多重事件排列）
While I was waiting for the bus, I saw an accident. A car was going too fast and it hit a tree. The driver was talking on his phone.
三层时态嵌套：
- was waiting — 我的背景
- saw, hit — 突发事件
- was going, was talking — 事故发生时司机的状态
📖 Real English · 真实阅读
🔵 The Night the Lights Went Out
It was a cold November evening. Mrs. Parker was cooking dinner in the kitchen. Her husband was reading the newspaper in the living room. Upstairs, their two children were doing their homework. The dog was sleeping by the fire. Everything was quiet and peaceful. Then, at exactly 7:15 p.m., all the lights went out. The whole street was suddenly dark. Mrs. Parker dropped her spoon. The children screamed. Only the dog kept sleeping.
🔵 Where Were You When…?
Everyone remembers where they were when something big happened. On July 20, 1969, Neil Armstrong was walking on the moon for the first time. Millions of people around the world were watching on their televisions. Some were crying with joy. In a small town in Ohio, Armstrong’s mother was sitting in her living room, watching her son take “one small step for man.” She later said she was praying the whole time.
🔵 The Mystery of Room 13
Detective Green arrived at the hotel at midnight. Rain was falling heavily outside. In the lobby, a woman was waiting for him. “Thank you for coming,” she said. “Something strange happened while I was staying in Room 13. I was taking a shower when I heard footsteps in my room. When I came out, my suitcase was open and someone had taken my passport. But the door was still locked from the inside.”
📝 中文注释（先读完英文再展开）
停电之夜：典型的过去进行时场景铺设——was cooking/was reading/were doing/was sleeping 描述”那个时刻各人正在做的事”，然后 went out/dropped/screamed 用过去时打断背景，制造戏剧效果。
你当时在哪：1969年阿姆斯特朗登月时，全世界都在看电视。was walking/were watching/were crying/was sitting/was praying——过去进行时描述”那个历史时刻每个人正在做的事”。注意 she said she was praying 是间接引语中的过去进行时。
13号房间之谜：侦探到达酒店，雨正在下（was falling），女人正在等他（was waiting）。核心句式：“I was taking a shower when I heard footsteps”——长动作（进行时）被短动作（过去时）打断。这就是书虫侦探故事的标准叙事节奏。
