Warm-up

Let's talk about technology.

1. Which gadget could you not live without? Why?
2. How would you feel if a stranger filmed you in public without asking?
3. Have you ever tried a VR headset or smart glasses? If not, would you like to?

Grammar rule

The future continuous

Use	Example
an action in progress at a time in the future	This time next week, I'll be skiing in Colorado.
an action that will be in progress when something else happens	When you call, we'll be having dinner.
a polite question about someone's plans	Will you be paying by card?

Form: will + be + -ing (I'll be working, she won't be coming, will they be staying?).

After when, before, after and as soon as, use the present simple, not will: when you call (not when you will call). Verbs for states (know, want, believe) don't usually take -ing: I'll know the results tomorrow. The unit's grammar lesson practices the future continuous fully, with be about to and be due to.
