Grammar explanation

Future continuous

We can use the future continuous (will/won't be + -ing form) to talk about future actions that: 

  • will be in progress at a specific time in the future:

When you come out of school tomorrow, I'll be boarding a plane.
Try to call before 8 o'clock. After that, we'll be watching the match.
You can visit us during the first week of July. I won't be working then.

  • we see as new, different or temporary:

Today we're taking the bus but next week we'll be taking the train.
He'll be staying with his parents for several months while his father is in recovery.
Will you be starting work earlier with your new job?

Future perfect

We use the future perfect simple (will/won't have + past participle) to talk about something that will be completed before a specific time in the future.

The guests are coming at 8 p.m. I'll have finished cooking by then.
On 9 October we'll have been married for 50 years.
Will you have gone to bed when I get back?

We can use phrases like by or by the time (meaning 'at some point before') and in or in a day's time / in two months' time / in five years' time etc. (meaning 'at the end of this period') to give the time period in which the action will be completed.

I won't have written all the reports by next week.
By the time we arrive, the kids will have gone to bed.
I'll have finished in an hour and then we can watch a film.
In three years' time, I'll have graduated from university.

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.
All the best

No grammar book (and I've got about a dozen of them) explains the difference between Future Simple and Progressive in similar sentences and why they can be used interchangeably. That's why I decided to ask my questions here, and now I seem to understand that, thanks to you.
