Hi, my name is Rosa. I'm in the Canadian city of Montreal with my mum and dad. It's a fantastic city. My aunt lives
here and we're with her for a month. Montreal is a very interesting place. It's the biggest bilingual city in the world
-a lot of people speak English and French. People speak to mein French in the shops, but when I don't
understand they speak in perfect English! Mum speaks French fluently. She uses her French every day, but she
doesn't understand some Canadian French words. Montreal is very friendly and there are people from many
different countries. We go to Italian cafes " Little Italy" part of the city or to Chinese restaurants in the"
Chinatown" area. My favourite place is the Mount Royal Park - it's got an amazing view of the city.
Answer the questions. Write complete sentences.
