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. I have a question about Future Perfect Continuous.
Is it possible to use 'since' in this tense, like to say that:
In 2020 I will have been living in France since 2017.
I know that since is generally used for the past but is it possible to use it anyhow in a future tense?? Thanks in advance for your answer.

I think you should be in France now

Hello kudlata,

Yes, you can use 'since' with the future perfect continuous – your sentence is perfect! Congratulations!

I'm confused by the last example:
"I promise I’ll have done all the work by next Saturday."

Can I say: "I promise I'll finish all the work by next Saturday. " ?

What's the difference?


Hello cleaner,

Yes, you can say that. The two forms take slightly different perspectives on the event, but they mean the same thing. The form you asked about (with 'will') is more commonly used than the future perfect form.

can i say "I think Alex will leave the quiz?" it doesn't satisfy any parallelism. 'think' is in the present tense and 'will leave' is in future. Is there anything wrong in my judgment? Kindly correct me please

Hello wisefool,

Yes, that's a correctly formed sentence. It uses 'will' to make a prediction about the future.

We usually say that many and much are used in negative sentences, even so , on the Cambridge dictionary there a lot of positive sentences about many such as There are too many people chasing too few jobs, Rachel was at the party with her many admirers.

And second question,
Could you explain me difference between a coffee and some coffee (e.g what is a coffee ? what is some coffee ) and some ice cream, an ice cream. P.S i know that they are countable and uncountable but i can not imagine them as a chocolate and some chocolate ...

Hi seaara,

The key word in your first question is 'usually'. When we analyse frequency we can see that 'much' and 'many' are used most often in negative sentences, but they can be and are used in affirmative sentences too and that is why examples of these are given.

The countable forms of the words you give are commonly bought or served units. So, if I say 'I have some coffee' then I mean the substance (beans, powder, liquid), but if I say 'I have a coffee' then I mean a cup of coffee. Similarly, an ice cream means one cone, for example, and a chocolate means one piece from a box.


Best wishes,
