Bonjour
mettre à la voix passive =
1- A standarized admission test must be taken by international students.
2-An F1 visa will be needed by students to work during their studies.
3- A financial boost in recent years from international students has been received by US colleges and universities.
4- Optional Partical Training (OPT) is being developed by American higher education.
voix passive, concordance des temps =
n° 1 & 4 = modal + infinitif ==> modal + be + p. passé
n° 3 = present perfect ==> p. perfect continuous : have[present] + been + p. passé
n° 4 = présent be + ing ==> be [présent] + being + p. passé
bonne fin de journée :)
