Bonjour,
Le passif n'est pas un temps. Dans l'exercice il n'est pas précisé à quel temps il faut mettre les phrases. ( les verbes de la consigne étant à l'infinitif ).
J'ai donc mis chacune des phrases au prétérit et au présent* et au futur'' ... mais on peut aussi les mettre au présent perfect ...
a. The Teen Summit was organised by talented artists.
a * . The Teen Summit is organised by talented artists.
a'' the Teen summit will be organised by talented artists
b. The opportunity to express themselves was given to teens.
b *. The opportunity to express themselves is given to teens.
b'' The opportunity to express themselves will be given to teens.
c. Poetry was spoken by youth performer Bintou.
c.* Poetry is spoken by youth performer Bintou.
c'' Poetry will be spoken by youth performer Bintou.
d. Artivist love letters were written at the Teen Summit
d. *Artivist love letters are written at the Teen Summit
d'' Artivist love letters will be written at the Teen Summit.
Explications :
PASSIF = SUJET + BE ( CONJUGUÉ AU TEMPS DE LA VOIX ACTIVE ) + PARTICIPE PASSÉ ( 3ème colonne des verbes irréguliers )
