bonjour
1- If I were the Head of the school, I would tell the teachers not to give us too much homeworks.
2- If I met Guillaume Canet, I would ask him to meet Marion Cotillard.
3- If I saw my idol in the streets, I would take a selfie to proove I met him. 4- If I were you , I would download Avici music ( mets ce que tu aimes !!)
5- If my parents forbade me too surf the net, I would get mad !
6- If I were a drummer in an orchestra, I would realize my dream.
Pour BE, on dit bien "If I were" et non "if I was"
