Future Continuous has two different forms: “will be doing ” and “be going to be doing.” Unlike Simple Future forms, Future Continuous forms are usually interchangeable.
FORM-Future Continuous with “Will”
[will be + present participle]
FORM-Future Continuous with “Be Going To “
[am/is/are + going to be + present participle]
REMEMBER: It is possible to use either “will” or “be going to” to create the Future Continuous with little difference in meaning.
USE 1-Interrupted Action in the Future
Use the Future Continuous to indicate that a longer action in the future will be interrupted by a shorter action in the future. Remember this can be a real interruption or just an interruption in time.
Notice in the examples above that the interruptions (marked in italics) are in Simple Present rather than Simple Future. This is because the interruptions are in time clauses, and you cannot use future tenses in time clauses.
USE 2-Specific Time as an Interruption in the Future
In USE 1, described above, the Future Continuous is interrupted by a short action in the future. In addition to using short actions as interruptions, you can also use a specific time as an interruption.
In the Simple Future, a specific time is used to show the time an action will begin or end. In the Future Continuous, a specific time interrupts the action.
USE 3-Parallel Actions in the Future
When you use the Future Continuous with two actions in the same sentence, it expresses the idea that both actions will be happening at the same time. The actions are parallel.
USE 4-Atmosphere in the Future
In English, we often use a series of Parallel Actions to describe atmosphere at a specific point in the future.
Like all future tenses, the Future Continuous cannot be used in clauses beginning with time expressions such as: when, while, before, after, by the time, as soon as, if, unless, etc. Instead of Future Continuous, Present Continuous is used.
AND REMEMBER-Non-Continuous Verbs / Mixed Verbs
It is important to remember that Non-Continuous Verbs cannot be used in any continuous tenses. Also, certain non-continuous meanings for Mixed Verbs cannot be used in continuous tenses. Instead of using Future Continuous with these verbs, you must use Simple Future.
The examples below show the placement for grammar adverbs such as: always, only, never, ever, still, just, etc.
ACTIVE / PASSIVE
NOTE: Passive forms of the Future Continuous are not common.
