My name is Damian Costa. I was born in a small village in Italy in 1952. I spent the first few Years of my life there before my family1to Perth Australia.

    We arrived in Australia in the summer of 1957. I went to2and I had to attend special classes to learn English as all the lessons were taught in English.

    We did not have much3, so we lived very simply. My parents worked as cleaners. They earned（挣钱）just enough for us to survive（维持生活）and4 a little money. My father had always wanted to5a small restaurant. Finally.6ten years of hard work, in June1967, he managed to save enough and opened our first pizzeria（比萨饼店）.

    7business was slow at first, it soon got better. I helped out at the pizzeria after school and at weekends. Just two years after we8my father decided that we needed a full-time waiter. Then he decided to9me the art of making wood-fired pizzas.

    Today we have three branches(分店), in Perth. Sydney and Adelaide. My children have10learned how to make pizzas and they quite enjoy it. I hope to pass on the business to them.
