|I will have sung|
How do we make the Future Perfect Tense?The structure of the future perfect tense is:
|subject||+||auxiliary verb WILL||+||auxiliary verb HAVE||+||main verb|
|subject||auxiliary verb||auxiliary verb||main verb|
|+||You||will||have||forgotten||me by then.|
|I will have||I'll have||I'll've|
|you will have||you'll have||you'll've|

We sometimes use shall instead of will, especially for I and we.
How do we use the Future Perfect Tense?The future perfect tense expresses action in the future before another action in the future. This is the past in the future. For example:
- The train will leave the station at 9am. You will arrive at the station at 9.15am. When you arrive, the train will have left.
|The train will have left when you arrive.|
|Train leaves in future at 9am.|
|You arrive in future at 9.15am.|
- You can call me at work at 8am. I will have arrived at the office by 8.
- They will be tired when they arrive. They will not have slept for a long time.
- "Mary won't be at home when you arrive."
"Really? Where will she have gone?"
