will + have + been

OK, I give up on this one.

My test asks me to explain the choice of "..... 'will have been' collected", the only reference I can find of will + have + been also has to include the gerund (ing) which makes the whole thing Future Perfect Continuous.

The whole sentence reads: Before the film begins all the tickets 'will have been' collected; no use of the gerund here??!!

The question goes on to ask me to explain "under what circumstances is the alternative answer 'are being' possible?"

This is holding me up from submitting my first module, I've been struggling with it on and off for over 2 weeks; any help would be most gratefully received.

Ta muchly

PS:  I've been dipping in and out of the site for a couple of months and it has proved extremely useful, so thank you for the help I've already received unbeknown to yourselves. H

PPS: You may gather that grammar is not my strongest point - so please be gentle with any replies. H

I'm going to try to help.

Future Perfect Simple, which is the tense used in your sentence, serves to indicate that an action that will take place in the future will be completed before another future action occurs.

In your sentence, the speaker makes an observation concerning two future actions (A: the film starts B: tickets are collected) and states now that B will be finished before A occurs, this is why FPS is used here.

Compare with the following:

"Before the film begins, all tickets will be collected".

This is different. The speaker here simply states that a future action will occur before another one and that's all.
In your original sentence, the speaker insists on the fact that one future action will be finished before another future action.

The only use of "are being" I can think of would be "Tickets are being collected before the movie begins"; in that case, the meaning is different: the speaker does not insist on the fact that an action is finished but rather is witnessing this action in process (e.g. the speaker is watching a person who is busy collecting the tickets before the movie starts and states that the action is occurring at the time he/she is speaking).

It's hard to explain though, is it clearer now?

Thanks Waiti

I was still online when your response came through - great service!  I'm not sure that the answer requires me to change the sentence; I think it has to stand as it is.  I just have explain what is being tested by adding 'will have been' to the given sentence.

As I said in my original posting grammar is not top of the pops in my old brain so will have to do some homework on active and passive forms 'cos I got the ghist of what you where saying and want to know more!

Many thanks

Many thanks CJ

This has given me lots to go on.  Had to read it twice to understand it all but I reckon I've got it.

Thanks again to all who have replied

PS: How do I sign this off as 'completed'?
