## Step 3 - Grammar

Let’s look at ... future perfect continuous.
"This year, I will have been doing this for a decade."
- We use the future perfect continuous to talk about something that started in the past, and will continue into the future. We can add a reference point.
For a decade, by this time next week, in 2 hours’ time.
We can also use it to express cause and effect.
Steiner will be tired because he will have been sitting for nearly 5 hours.
You use will + have + -ing.
- We use the future perfect simple (will have + past participle) to talk about something that we are sure is going to be completed in the future.
We sometimes say when it will be completed.
I’ll have finished my homework by the time Mum gets home.
