Bonsoir
Le present perfect BE + V-ing (ou present perfect continuous) se forme ainsi =>
have (au présent = have/has) + been + Base Verbale -ing
Il parle d'une action commencée dans le passé et qui a toujours un impact sur le présent ou qui vient se terminer.
le fait d'utiliser la forme "continuous" permet d'insister sur le déroulement de l'action.
for = durée générale (for weeks, for two months ...)
since = le point de départ (since yesterday, sinve 1988, since the 2nd of October ...)
