We look at the past from the future with the help of Future Perfect Continuous Tense. Let us take a look at its structure.
|subject||+||Auxiliary ‘will’||+||Auxiliary ‘have’||+||Auxiliary ‘be’||+||Main verb|
|invariable||invariable||Past participle||Present participle|
In the case of negative sentences in this tense, we put ‘not’ in-between ‘will’ and ‘have’.
In the case of question sentences, the subject and ‘will’ is exchanged.
Let us take a look at a few examples:
|subject||Auxiliary verb||Auxiliary verb||Auxiliary verb||Main verb|
Sometimes, we use ‘shall’ instead of ‘will’, mostly in the cases of ‘I’ and ‘we’.
While we speak with the help of Future Perfect Tense, very often we contract the subject and ‘will’.
- She’ll have been writing.
- I’ll have been eating at 9pm.
In case of negative sentences, we can contract ‘won’t’, something like this:
|I will not||I won’t|
|She will not||She won’t|
|He will not||He won’t|
|They will not||They won’t|
|We will not||We won’t|
- She won’t have been driving for long.
- You won’t have been eating, will you?
The Future Perfect Tense is more similar to the Future Perfect Tense, but with the addition of expressing longer actions or states which could extend up to some particular event pr time in the future. Remember that the long action or the state could start at any time in the past or present or the future, but it will always end in the future.
Remember that continuous tenses are also called progressive tenses, hence the future perfect continuous tense is sometimes called the future perfect progressive tense.
