Do you know when to use the future continuous (e.g. I'll be studying) and future perfect (e.g. I'll have studied)?

The future continuous (will be + ‘ing’ form) and the future perfect (will have + past participle) tenses are used to talk about events in the future.

Future continuous

  • Don’t ring at 8 o’clock. I’ll be watching Who Wants to be a Millionaire.
  • This time tomorrow we’ll be sitting on the beach. I can’t wait!

We use the future continuous to talk about something that will be in progress at or around a time in the future.

  • Don’t phone grandma now, she’ll be having dinner.
  • The kids are very quiet. They’ll be doing something wrong, I know it!

These sentences are not about the future but we can use the future continuous to talk about what we assume is happening at the moment.

Future Perfect

  • Do you think you will have finished it by next Thursday?
  • In 5 years time I’ll have finished university and I’ll be able to earn some money at last.

We use the future perfect to say that something will be finished by a particular time in the future.

We often use the future perfect with ‘by’ or ‘in

  • I think astronauts will have landed on Mars by the year 2020.
  • I’ll have finished in an hour and then you can use the computer.

By’ means ‘not later than a particular time’ and ‘in’ means 'within a period of time’. We don’t know exactly when something will finish.

  • I promise I’ll have done all the work by next Saturday.

We don’t know exactly when he will finish the work – maybe Thursday, maybe Friday – but definitely before Saturday.

Hi Sir
Could you tell me what this sentence means?

I'll be celebrating my mom's brithday tomorrow.

Does it mean I'm going to celebrate it the whole day tomorrow or does it express that I have a plan to celebrate my mom's birthday tomorrow (it doesn't matter what time I celebrate)?

Thank you Sir

Hello Risa warysha

It does mean you have a plan for tomorrow, but what else it exactly means is impossible to say for sure without knowing the precise context.

Hi teachers, i would like to know which is the most informal way with the same meaning of the following sentence: if i had waited for further one hour i would have met his.Thanks in advance .

Hello rosario70

If I've understood what you want to say, I'd recommend 'If I had wait another house, I'd have met him.'

Hmm! I'm happy to learn more about future continuous and future perfect. I am used to translate directly my sentences from french to english and some, that sounds weird and no sense. But now, I know when I have to use these tenses during my talking.

What is the difference between the following sentence?

When will you be arriving?
AND
When are you going to arrive?

Hello Montri,
Both sentences describe future time and have similar meanings.
The first sentence ('...will be arriving') describes something that is expected. We use this form to describe things that we see as normal and unsurprising in the future.
The second sentence ('...going to...') describes a person's intention or plan.

Hello
Would you ever use 'would' in a future perfect construction? Is there a rule, e.g. By the time I am 30 years old I will have owned a Ferrari. Or would it be: By the time I am 30 years old I would have owned a Ferrari.
Thanks!

Hello Jennief
'would have owned' doesn't work with 'by the time I am' because 'would have owned' refers to an (unreal) imaginary time and 'by the time I am' refers to a (real) future time. You could say, for example, 'I would have owned a Ferrari when I was 30 is I hadn't been sacked.' This refers to an unreal past time, i.e. a past in which you were not sacked.

Hello.
Is the future perfect correct in this sentence or we must use "will own"?
By the time I am 30 years old I will have owned a Ferrari.
Thank you.
