一、语法概述

1.用法: 强调从过去视角看动作持续到将来某一时间点。

2.结构: 主语 + would have been + 动词-ing   

3.标志词: by…for    

二、句型结构

1.肯定句（Affirmative Sentence）：主语 + would have been + 现在分词（doing） + 其他（常与 by + 将来时间 或 when 引导的从句连用） 

She said she would have been working at the company for 10 years by next month.

（她说到下个月，她就已经在这家公司工作满10年了。）

2.否定句（Negative Sentence）：主语 + would not/wouldn’t have been + 现在分词（doing） + 其他

（老师认为到音乐会时，学生们练习这首歌的时间还不够长。）

3.一般疑问句（General Question）：Would + 主语 + have been + 现在分词（doing） + 其他？

肯定回答：Yes, 主语 + would.

否定回答：No, 主语 + wouldn’t.

5.核心用法总结: 

1. 结构：would have been + 现在分词（doing），强调“从过去某一时间看，到将来某一时间为止一直持续的动作”，具有持续性和未完成性（可能仍会继续）。

2. 时间状语：常与 by + 将来时间（如：by next month, by 2025） 或 when/by the time 引导的将来时间从句连用，明确动作的截止点。

3. 语境：多用于宾语从句（如：said, believed, thought 等引导的从句），以过去视角谈论将来某一时间前的持续动作，类似“过去的将来的完成进行”。
