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.
