How to use the future perfect continuous tense – English In A Minute

Hi, I’m Tom and today I’m going to show you
how to use the future perfect continuous.
When we use the future perfect continuous,
we imagine ourselves at a point in the future
and we then talk about a continuing action
which leads to this point.
Let’s practise.
At the start of the next scene,
I will have been eating noodles for five minutes.
See?
It’s nearly finished!
We make this tense using
subject + will have been + (verb)ing.
For example:
At lunchtime, I will have been working for four hours.
And we can also use ‘won’t’
to make the tense negative.
