Future Perfect Continuous
Future Perfect Continuous is used to indicate a continuous
action in the future
Note that continuous tenses
are also called progressive tenses. So the Future Perfect Continuous
tense is sometimes called the Future Perfect Progressive tense.
FORMULA / STRUCTURE

(an-ing)]
Fourth form of verb is called Present Participle form and an –ing form.

RECOMMENDATION
INTERMEDIATE LEVEL
→ By our 20th wedding anniversary, this plant will
have been growing for 15 years.
(i) When we explain an action in the future perfect
continuous tense, we are projecting ourselves forward in time and looking
back at the duration of that activity. The activity will have begun sometime in
the past, present, or in the future, and is expected to continue in the future.
→ When I turn thirty, I will have been
playing piano for ten years.
→ In October, I will have been
working at my factory for seven years.
→ At four o’clock, I will have been
waiting for an hour.
(iii) state verbs do
not use the future perfect continuous
State verbs like be, seem, or know are not suited to
the future perfect continuous tense. We use the future perfect tense.
→ On Monday, I will have known you
for two weeks.
NOT On Monday, I will have been
knowing you for two weeks.
(iv) Shall
Uncertain
future : I or We → shall
I shall, We shall
Certain Future
: I or We → will
I will, We
will
↷ I will
go there.
(= means I shall definitely go there.)
Uncertain
future : The Rest → will
You will, He
will, she will, it will, they will
Certain Future
: The Rest → shall
You shall, he
shall, she shall, it shall, they shall
↷ He shall
pass the examinations.
(= means he will definitely pass the examinations.)
↷ The form shall
not be submitted after February.
(= means it will not be
submitted after February at any cost.)
We can be certain
about ourselves, but we cannot be certain normally about others. That’s why
usage of shall becomes less.
If you have
confusion do practice or use only “will”.
(v) Read this:
[Reference:
(Second Edition) Oxford Practice Grammar by John Eastwood Unit 22]
We know about things in
the present and in the past because they are already real. But talking about
the future is more of a problem.
There is no single form in English that we can always use for the future. There are many different ways of talking
about the future, depending on how we see a future event. It may be something that is fairly sure to
happen, but on the other hand it may be just a plan or an intention, or it may be something that you think will
happen but you can't be sure about.
(vi) Usage of Since and For
We use frequently
‘since’ and ‘for’ for these tenses.

'Since' and 'For'
We use 'since' with a fixed time (starting point) in the past (2004,
23rd April, last year). The fixed time can be another action, which is in the
past simple (since I was at school, since I arrived).
↷ I have known Aslam since 1992.
↷ She has been here since 2 pm.
↷ You have liked chocolate since you were a child.
We use 'for' with a period of time (2 hours, three years, six months).
↷ I have known Maria for ten years.
↷ He has worked here for six months.
↷ I have known you for a week.
We use how long in questions.
↷ How long have they been married? ~ Oh, for about four years.
↷ How long has Vicky had that camera? ~ Since Monday.
We can also use the present perfect with for and since
when something has stopped happening.
↷ He hasn't
visited us since July.
↷ You haven't
seen your uncle for ages.
