Future continuous and future perfect

Grammar explanation

Future continuous

زمان آینده استمراری نشان میدهد که کاری در زمان آینده صورت خواهد گرفت و برای مدتی ادامه خواهد داشت.

We can use the future continuous (will/won't be + -ing form) to talk about future actions that: 

• will be in progress at a specific time in the future:

When you come out of school tomorrow, I'll be boarding a plane.
Try to call before 8 o'clock. After that, we'll be watching the match.
You can visit us during the first week of July. I won't be working then.

• we see as new, different or temporary:

Today we're taking the bus but next week we'll be taking the train.
He'll be staying with his parents for several months while his father is in recovery.
Will you be starting work earlier with your new job?

Future perfect

ما برای صحبت در مورد چیزی که قبل از یک زمان خاص در آینده تکمیل شود ، از آینده کامل ساده استفاده می کنیم.

We use the future perfect simple (will/won't have + past participle) to talk about something that will be completed before a specific time in the future.

The guests are coming at 8 p.m. I'll have finished cooking by then.
On 9 October we'll have been married for 50 years.
Will you have gone to bed when I get back?

We can use phrases like by or by the time (meaning 'at some point before') and in or in a day's time / in two months' time / in five years' time etc. (meaning 'at the end of this period') to give the time period in which the action will be completed.

I won't have written all the reports by next week.
By the time we arrive, the kids will have gone to bed.
I'll have finished in an hour and then we can watch a film.
In three years' time, I'll have graduated from university.
