核心规则（Grammar Core）
规则一：叙述时态统一
一篇叙述文（story / narrative）中，选定一个基准时态后全文保持一致，不随意混用。
| 叙述类型 | 基准时态 | 典型信号词 |
|---|---|---|
| 过去的故事 | 一般过去时 | yesterday, last…, in 2010, once |
| 现在发生的叙述 | 一般现在时（历史现在时） | 书评/影评/描述情节 |
| 未来的计划 | will / going to / present continuous | tomorrow, next… |
❌ 混用：I walked into the room. There IS a cat on the chair.
✅ 统一：I walked into the room. There WAS a cat on the chair.
规则二：时间信号词强制切换
某些时间信号词强制要求特定时态，即使叙述基准是过去时也要切换：
| 信号词 | 强制时态 | 例句 |
|---|---|---|
| before + 从句 | 主句用过去完成时 | She had left before he arrived. |
| after + 从句 | after 从句用过去完成时 | After she had finished, she left. |
| by the time | 过去完成时 | By the time I arrived, the film had started. |
| when（两件事同时） | 两个过去式 | When she walked in, everyone stood up. |
| while | 过去进行时 + 过去式 | While she was reading, he called. |
| as soon as | 两个过去式 | As soon as he saw me, he smiled. |
规则三：过去事件的序列
叙述中有两件事情先后发生，先发生的用过去完成时（had + V3）：
先发生 ────────────────── 后发生 ──────────────── 说话时间
had finished arrived
"When I arrived, she had already finished dinner."
我到达（后发生）← she had finished（先发生）
不需要过去完成时的情况：
| 场景 | 例子 |
|---|---|
| 用 after/before 已经表明顺序 | After he left, she cried.（after 已经表明顺序，可用一般过去时） |
| 事情发生得太自然，顺序明显 | She got up, washed her face and went to school. |
Grammar Lens
对比辨析：when 引发的时态选择 ⚠️
when 后面是什么时态，取决于两件事的关系
关系 结构 例句 同时发生 when + 过去式, 过去式 When the bell rang, everyone sat down. A 打断了 B（B 进行中） when + 过去式, 过去进行时 When she called, I was sleeping. A 发生在 B 之前（A 先完成） when + 过去式, 过去完成时 When I arrived, she had left. 区别关键：先看两件事谁先谁后，再选时态。
对比辨析：过去完成时 vs 一般过去时
"She told me that she saw the film."
→ 两件事可能同时 / saw 先发生不确定 → 一般过去时 ✅
"She told me that she had seen the film."
→ 明确说明 saw 发生在 told 之前 → 过去完成时 ✅
原则：有 by the time / before / already 等信号词时，必须用过去完成时；否则上下文清晰时可用一般过去时。
历史现在时（Historic Present）
书评、影评、故事概括用一般现在时讲过去的事，是英语中常见的文体：
In the story, Harry Potter DISCOVERS he is a wizard. He LEAVES the Dursleys and ARRIVES at Hogwarts...
这不是时态错误，而是一种文体选择。一旦选了历史现在时，全篇必须统一，不能混入过去时。
😂 Grammar Joke
The Time Traveller's Dilemma
A time traveller walks into a bar. A time traveller walked into a bar. A time traveller had walked into a bar. A time traveller will walk into a bar. A time traveller is walking into a bar.
The bartender asks: “What’ll it be?” The time traveller replies: “What’ll it be, what it was, or what it had already been — that depends entirely on your frame of reference.”
时间旅行者的问题：同一件事，用哪个时态取决于”说话时间点”。这正是时态一致性的核心：永远要有一个明确的参照时间点。
🏛 语言文化光点
为什么英语有这么多时态？
英语的时态系统是日耳曼语言（古英语）和法语（诺曼征服后）长期混合的产物。古英语本身时态就比较复杂，法语又带来了”动作完成了没有”这个视角（体：aspect），催生了完成时系列（have + V3）。
中文没有形式时态——中文用”了/着/过”表达时间关系，而不是改变动词本身的形式。所以中文母语者学英语时态，本质上是在学一套用动词形式表达时间关系的编码系统。
把”时态”想象成一台相机：
- 过去式 = 已经拍好的照片
- 过去进行时 = 拍摄当时正在曝光的照片
- 过去完成时 = 拍摄前就已洗印好的旧照片
例题精讲
例1（📙 PET · 改错叙述混用）
I walked into the café and there are two people sitting by the window. I order a coffee and sit down.
答案：叙述基准是过去时 → 全部改为过去时： “I walked into the café and there were two people sitting by the window. I ordered a coffee and sat down.”
例2（📙 PET · by the time）
By the time we arrived at the station, the train _____ (already / leave).
答案：had already left。by the time + 过去式 → 主句用过去完成时。
例3（📙 PET · 序列）
After she _____ (finish) the report, she _____ (send) it to her manager.
答案：had finished / sent。finish 先发生 → 过去完成时；send 后发生 → 一般过去时。 （或：After she finished the report, she sent it. ← after 已表明顺序，两个一般过去时也可接受。）
例4（📕 FCE · 书评历史现在时）
In the novel, the protagonist _____ (struggle) with his identity throughout the story. He _____ (make) a series of mistakes before finally _____ (find) peace.
答案：struggles / makes / finding。书评用历史现在时，全篇统一。
例5（中考 · when 选择）
When I _____ (get) home, my mother _____ (cook) dinner.
答案：got / was cooking。我到家（when + 过去式），妈妈那时正在做饭（过去进行时，表示动作正在进行被打断）。
📖 Real English · 真实阅读
🔵 The Lost Letter
Maria found the letter in an old drawer. She sat down and began to read. The handwriting was faded but clear. Her grandmother had written it in 1962, before she had left her hometown for the last time. In the letter, she described the village as it had been when she was young — the market that opened every Sunday, the river where children swam in summer. By the time Maria finished reading, her tea had gone cold. She did not notice. She was already somewhere else, somewhere long before she was born.
🔵 The Interview
“Tell me about a time when you solved a difficult problem,” the interviewer said. James took a breath. He described a project at his previous company. The system had crashed the night before the deadline. By the time his manager arrived, James had already found the error and fixed it. He had rewritten two sections of code, tested everything, and sent the updated report — all before 7 a.m. “How long had you been working when your manager came in?” the interviewer asked. “About four hours,” James said. “I had forgotten to sleep.” He got the job.
🔵 The Ancient Map
In the story, a young explorer named Zara discovers an old map in her uncle’s library. She studies it carefully and realises that the map shows a place that no longer exists. She travels for weeks before she finally reaches the coast. When she arrives, she finds that the city the map once showed has sunk into the sea. She stands at the edge of the water and looks down. In the clear blue depths, she can see the outlines of buildings, streets, and squares — everything that had once been there, now frozen in time.
📝 中文注释（先读完英文再展开）
失落的信：全文基准是过去时。“had written”（写信先于 found，用过去完成时）；“had been when she was young”（那时候是什么样子，过去完成时）；“had gone cold”（茶变凉先于 noticed，过去完成时）。注意过去完成时表示”更早之前”的事情。
面试：面试中描述的故事是过去中的过去——“had crashed”（系统崩溃）先于”arrived”（经理到来）。“had already found…fixed…rewritten…tested…sent”——五个过去完成时串联，全部发生在经理到来之前。“How long had you been working”——过去完成进行时，询问那时之前持续了多久。
古地图：故事概括用历史现在时（discovers, studies, realises, travels, arrives, finds, stands, looks）——全程现在时，除最后 “had once been there” 用过去完成时（表示地图显示的那个时代早已过去）。
