Future Perfect Continuous Tense

I will have been singing

How do we make the Future Perfect Continuous Tense?
The structure of the future perfect continuous tense is:

subject + auxiliary verb + auxiliary verb + auxiliary verb -+- main verb
--------------- WILL--------------HAVE-----------------BE
--------------invariable --------invariable ----------past -----------present
-------------------------------------------------------participle -------participle
----------------will ----------------have -------------been -----------base + ing

For negative sentences in the future perfect continuous tense, we insert not between will and have. For question sentences, we exchange the subject and will. Look at these example sentences with the future perfect continuous tense:

subject - auxiliary --------- auxiliary ------- auxiliary --------- main
------------verb----------------verb--------------verb----------------verb
+ I -------- will ---------------- have ------------ been ----------- working ------ for four hours.
+ You ---- will ---------------- have ------------ been ----------- travelling ----- for two days.
- She----- will ------ not ---- have ------------- been ----------- using --------- the car.
- We ----- will ------ not ---- have ------------- been ----------- waiting ------- long.
? Will ----- you --------------- have ------------- been ----------- playing ------- football?
? Will ----- they -------------- have ------------- been ----------- watching ------ TV?


When we use the future perfect continuous tense in speaking, we often contract the subject and auxiliary verb:




I will ----- I'll
you will ----- you'll
he will ----- he'll
she will ----- she'll
it will ----- it'll
we will ----- we'll
they will ----- they'll

For negative sentences in the future perfect continuous tense, we contract with won't, like this:






I will not ----- I won't
you will not ----- you won't
he will not ----- he won't
she will not ----- she won't
it will not ----- it won't
we will not ----- we won't
they will not ----- they won't


How do we use the Future Perfect Continuous Tense?
We use the future perfect continuous tense to talk about a long action before some point in the future. Look at these examples:

•I will have been working here for ten years next week.
•He will be tired when he arrives. He will have been travelling for 24 hours.
