How do we make the Future Perfect Continuous Tense?

The structure of the future perfect continuous tense is:

subject	+	auxiliary verb WILL	+	auxiliary verb HAVE	+	auxiliary verb BE	+	main verb
		invariable		invariable		past participle		present 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 verb		auxiliary verb	auxiliary verb	main 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 she will it will	he'll she'll 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 she will not it will not	he won't she won't 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.
