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 looked at Cambridge's grammar book and it is written that future simple is used for the things that will definetly happen and we cannot control.
Example: Jill will be 2 years old next month.
The colour of the moon will turn into red tomorrow night.
Also, it is written that future continuous is used for the things that will defiently happen as a consequence of a routine or arrangement.
Example: He will be working as a lifeguard in the summer.
Don't ask him. I'll be seeing him anyway in the meeting.

These 2 are too similar and confusing. For example, there is a question in my grammar book. It is like this:
I ... turn 20 in 2 weeks' time.
A)will turn
B)will be turning.
I thought that either one could be used but the answer is B. I could not understand why. Can you explain it tome please?

Hello Jack Red,

You are right that both forms (will turn and will be turning) are correct here.

 

I think the explanations you quote are only examples of uses, not the only uses possible. It's quite possible to use will + verb to describe choices (things we control), for example, as well as things we do not control. It's also quite possible to use will be + verbing to describe things that we expect (in the present as well as the future) as part of a normal and predictable process.

Dear Sir,

In my book is a sentence: " We also use will be-ing to talk about complete actions in the future." Could you explain to me what ''complete actions'' mean? Can I use Future Continuous to talk about what will be finished in the future? I thought we use Future Simple then. Please help me.

Best regards,
Zuzanna

Hello Zuzanna,

I'm afraid I can't think of an example for that usage off the top of my head -- that sounds strange to me. Sorry!

Hi.

I have a question about this sentence:

“I’ve never felt more invisible than when I’m traveling with her. She’ll be wearing a neon Gucci sweatsuit and a pair of white pumps”.

Is “She’ll be wearing” future continuous, even if the action described is not in the future, but it’s something that the person that the speaker knows usually does?

Hello Paula81,

I'd need to see the full context for these sentences to be able to explain the future continuous form here with full confidence, but I expect that 'will' is being used to talk about typical behaviour here. It sounds as if the writer is thinking of what typically happens when he or she travels with this person.

This is an advanced use of 'will' that is analogous to the use of 'would' to speak about typical past behaviour. You can see a short explanation of this use of 'will' under the section Habitual events on this Cambridge Dictionary page; there's an explanation of this use of 'would' on our Talking about the past page, under Past events and situations.

Hope this helps you make sense of it -- it's great that you noticed it!

All the best,

Which sentence is correct?

The revision of Mid Term Exam will be started on Monday.

Or

The revision of Mid Term Exam will be starting(will start)on Monday.

I want to tell the students that their revision is going to start from Monday,
in this case which of the above two sentences are correct?

Hello SaraZaber,

You could use either of the sentences, but I'd recommend the second one. If you use the passive voice (first sentence), it suggests the revision is more mechanical, as if it were something that will happen whether or not the students participate. The second one doesn't have this same sense.

It's a subtle difference and up to you which is better. You could also make it even more active by saying 'We will begin the revision for the mid-term exam on Monday'.

All the best,

When given as a 'Notice' shall I still use the first sentence?
(will be started)

Hello again SaraZaber,

I would use the second one. The first one is grammatically correct, but sounds more formal than any situation I've ever taught in. But if you think the first one is more appropriate for your context, that might be a better choice.

All the best,
