French language Q&A Forum

In the audio file for the sentence "Nous mourons tous un jour" in this lesson, the word "tous" has a silent s (IPA [tu]). Why is this? I understood that when "tous" is used as an indefinite pronoun to refer to a group of people like this, the s should be pronounced (IPA [tus]). Have I misunderstood something here? I would appreciate any help on this :)

I knew it must be Je, but it sounded like Tu.

Hi, I really enjoyed this exercise but want clarification on the sentence "Elle était en larmes !"

I would assume that this action was a one-off, not a continual state, so I used the passé compose (Elle a été). 

Is it because the sentences prior all used the imparfait?

Thanks

J'ai utilise "ce nouveau cahot" au lieu de "ce nouveau chaos".  Est-il assez pareil en sens?

He does not say 'installent DES projecteurs et DES caméras' as I would have expected. Is what he says an acceptable grammatical alternative?

A million years ago when I was at school doing French dictees, the teacher would read out the punctuation. Would it be possible to do that, too? I don't feel like docking points off my score because I put a full stop rather than an exclamation mark! 

Is complète an acceptable alternative to 'finit' ? 

My understanding is that for a general comment, 'C'est' is used when followed by any determiner.
