Future Tense Questions Medium
To form the future perfect continuous in the past tense, we use the auxiliary verb "would have been" followed by the present participle (-ing form) of the main verb. The structure is as follows:
Subject + would have been + present participle
For example:
- I would have been studying for five hours by the time you arrived.
- They would have been working on the project all day yesterday.
- She would have been waiting for him since morning.
In these examples, the future perfect continuous in the past tense is used to express an ongoing action that would have been happening at a specific point in the past.
