MY
FAMILY

I am Alex Sidorov. Alex is my first name and Sidorov
is my surname. I am seventeen years old. I want to tell you a few words about
my family. My family is large. I've got a mother, a father, a sister, a brother
and a grandmother.

There are six of us in the family.

My mother is a teacher of biology. She works in a
college. She likes her profession. She is a good-looking woman with brown hair
and green eyes. She is forty-four but she looks much younger. She is tall and
slim.

My father is a computer programmer. He is very
experienced. He is a broad-shouldered, tall man with fair hair and grey eyes.
He is forty-six. My father often sings and when we are at home and have some
free time, I play the guitar and we sing together. My father knows all about
new radio sets and likes to repair old ones. He is also handy with many things.
When he was small, he liked to take everything to pieces. My grandmother told
me a story that once my father tried to "repair" their kitchen clock.
He managed to put all the wheels and screws back again — but the clock did not
work. They had to give it to a repairman. But that happened a long time ago.
Now he can fix almost everything: a vacuum cleaner, a washing machine, a fridge
and what not. He's got a few shelves where he keeps everything he needs. On the
table there's always a radio in pieces.

My parents have been married for twenty-six years.
They have much in common, but they have different views on music, books and
films. For example, my father likes horror films and my mother likes "soap
operas". My father is fond of tennis. My mother isn't interested in
sports. But my parents have the same opinion about my education and upbringing.


My parents are hard-working people. My mother keeps
house and takes care of me and my father. She is very good at cooking and she
is clever with her hands. She is very practical. My father and I try to help
her with the housework. I wash the dishes, go shopping and tidy our flat.

My grandmother is a pensioner. She lives with us and
helps to run the house. She is fond of knitting.

My sister Helen is twenty-five. She is married and has
a family of her own. She works as an accountant for a small business company.
Her husband is a scientist. They've got twins: a daughter and a son. They go to
a nursery school.My brother Boris is eleven. He is a schoolboy. He wants to
become a doctor but he is not sure yet. Three months ago he dreamed of being a
cosmonaut.

I want to become a student. I'd like to learn foreign
languages. I think I take after my father. I'm tall, fair-haired and
even-tempered. I always try to be in a good mood.

We've got a lot of relatives. We are deeply attached
to each other and we get on very well.
