L1 = Mathieu as-tu vu ce film (passé composé interrogatif: tu as vu = as-tu vu? ) voyé = doesn't exist !! Voir is the infinitive. as it is the "passé composé" with avoir, tou have to use the past participle = vu
L2 = Oui je viens de regarder ce film (I've just seen this movie) je sors = I go out je pars = I leave
venir de = when you have just done something ex: = I just bought a pair of shoes = je viens d'acheter des chaussures I just came back home = je viens de rentrer à la maison
L4 = Viens plutôt avec nous (imperative forme singular 3rd person). venez could be alright for several persons.2nd person infintitive ex : Jean and Cathy instead of Jean alone . they would have been asked : "Venez" venir is the infinitive. Not conjugated
Sophie et moi sortons (are going out) pour aller au concert ce soir voyons = are seeing étudions = are studying
hope I helped you. I know "venir de" mustn't be so easy for you ...
- Matthieu, as-tu vu Les Trois Soldats? - Oui, je viens de regarder ce film ! - Je veux regarder ce film. - Viens plutôt avec nous; Sophie et moi sortons pour aller au concert ce soir.
