My name is Kate. I am ten. I am from Russia. I live in the village. I have got a family. My family is not large. I have got a mum, a dad and a brother. My mum is 35. And my dad is 40. My brother is in the 5th form.
I have got a friend. My friend Oleg lives in St.Petersburg. This is a big city. There are a lot of museums, cathedrals, theatres and cinemas in the city.
Oleg lives in a big house. There is a school near his house. Oleg goes to the 6th form. His favourite subjects are English and Russian.
On the right of his house there is a stadium and a swimming pool. Oleg plays football at the stadium and likes going to the swimming pool. He is good at swimming. On the corner of his street there is a big cathedral. On the left of the cathedral there are two cafés and a theatre.
