过去将来时
一、定义
过去将来时表示从过去某一时间点来看，将要发生的动作或存在的状态 。它强调“站在过去的视角，对未来动作或状态的预判”，核心逻辑是“过去的将来” 。比如：She said she would visit Beijing the next month.（她说她下个月会去北京，“said”是过去的动作，“would visit”是从过去看将来要发生的动作 ）。
定义解析——“站在过去看未来”
- 概念：以过去某一时刻为参照，描述当时看来“将要发生”的动作/状态
- 时间轴图示：过去（起点）→ 过去将来（预期动作）→ 现在（视角）
- 示例：He said he would come.（“said”是过去，“would come”是过去看将来 ）
基本结构（1）——常规形式
1. would + 动词原形（适用于所有人称）
- 例：He said he would come to the party.
2. was/were going to + 动词原形
- 例：They were going to visit the museum last week.
would + 动词原形
1. 用法：适用于所有人称，常用来表达单纯的过去将来动作或状态，多在间接引语中，转述过去对未来的计划、意愿等 。
2. 例句：He told me he would finish the work by Friday.（他告诉我他会在周五前完成工作，“told”是过去，“would finish”是过去视角里将来要做的事 ） ；I thought I would go to the park alone.（我那时想我会独自去公园 ）。
基本结构（2）——特殊形式
3. was/were to + 动词原形（表计划、安排，语气正式）
- 例：The meeting was to start at 3 pm.
4. was/were about to + 动词原形（表“即将发生”，不与时间状语连用）
- 例：I was about to leave when the phone rang.
was/were going to + 动词原形
1. 用法：一是表示过去有计划、有意图要做的事；二是可用来描述根据过去的迹象，判断即将发生的动作 。
2. 例句：They were going to have a party, but it was canceled.（他们本打算举办派对，但取消了，体现过去的计划 ） ；The dark clouds were gathering, and it was going to rain.（乌云在聚集，眼看就要下雨了，依据迹象判断将来 ） 。
was/were to + 动词原形
1. 用法：常用来表示过去按计划、安排必须要发生的动作，或用于正式语境、书面语中，强调“注定、应该”发生的事 ，也可表过去的命令、职责等 。
2. 例句：The meeting was to start at 9 o'clock.（会议原定9点开始，体现计划安排 ） ；He was to report the incident to the manager.（他本该向经理汇报这起事件，有一定职责、命令的意味 ） 。
was/were about to + 动词原形
1. 用法：表示过去“即将、马上就要”发生的动作，强调动作的即时性，通常不与具体时间状语连用 ，常和when引导的从句搭配，构成“be about to do... when...”结构，表“正要做…… 这时（另一件事发生）” 。
2. 例句：I was about to leave home when the phone rang.（我正要出门，这时电话响了 ） ；She was about to speak when the teacher came in.（她刚要发言，老师就进来了 ） 。
用法1——主句为过去时的宾语从句中
- 场景：间接引语中，转述过去的“将来计划”
- 例：She told me she would buy a new bike.
- 提示：直接引语→间接引语的时态变化（will→would）
用法2——过去的计划或安排
- 用“was/were going to”，强调“过去打算做但可能未做”
- 例：I was going to watch the movie, but I forgot.
用法3——虚拟语气中的过去将来时
- 用于if条件句（与过去事实相反）
- 例：If I had time, I would go with you.（隐含“过去没时间”）
用法4——描述过去的习惯性动作（较少见）
- 表“过去常常会发生”的将来动作
- 例：On weekends, he would always go fishing.
用法5——时间/条件状语从句中
- 主句为过去将来时，从句用一般过去时（“主将从现”的过去版）
- 例：She said she would call me when she arrived.
与相关时态的区别
1. vs 一般将来时：过去将来时以“过去”为参照点，将来时以“现在”为参照
- 例：He will go.（现在看将来）→ He said he would go.（过去看将来）
2. vs 一般过去时：过去将来时表“未发生”，过去时表“已发生”
- 例：He went.（已去）→ He said he would go.（过去计划去，未知是否实现）
虚拟语气中的过去将来时
场景：if条件句（与过去事实相反 ）
例句：If I had money, I would buy a car.（“had”是过去，“would buy”是过去看将来的虚拟 ）
