Future Perfect Continuous Tense
d) Future
Perfect Continuous Tense: It is used to
express a continued or ongoing action that will start in future and is thought
to be continued till sometime in future. (Remember, an ongoing action in future
which will continue till some time in future). There will be a time reference,
such as “since 1980, for three hours” from which the action will start in
future and will continue. A sense of time reference is found which gives an
idea that action will start at some time in future and will continue for some
time. Such time reference or sense of time reference is the identity of
Future perfect continuous tense because it tells that action will start at a
particular time in future.
Affirmative Sentence
Rules: Subject + shall have /
will have + been + verb + ing + since/ for + extension + time reference
Examples:
I will have been
waiting for him for an hour. She
will have been playing football since
2015.
For example:
He will have been studying in this
school since 2005.
Note: So it means that he will start studying in this school in 2005
and will study in this school till sometime in future. Note:
If there is not time reference or sense of time reference then it is not Future
Perfect Continuous Tense because there is no hint about the time of action when
it will start in future and it seems just an ongoing action in future, which
resembles ‘Future Continuous Tense’.
So the reference of time differentiates between Future perfect continuous tense
between Future Continuous Tense.
