What's your favourite season?

What's/ is your favourite season? Why? (=pourquoi?) My (=ma) favourite season is summer because (=parce que) it's hot and sunny (=il fait chaud et beau). And there are holidays (= vacances). I prefer autumn because it's my birthday (=anniversaire) ! I love winter because there is snow (=neige). I like spring because there are flowers (=fleurs). IL Y A = THERE IS + nom au singulier (ex: there is snow) THERE ARE + nom au pluriel (ex: there are flowers)
