She is а housewife. My younger sister is а pupil. She is in the seventh form. My grandmother lives with us.She doesn't work. She is а pensioner. I love my family. We are all friends and we love each other.
I have one aunt and two uncles. Their children are my cousins. We live in a big flat in а new house. There are four rooms in our flat: а living room, а study, а kitchen, а bathroom and two bedrooms. We have all modern conveniences: gas, hot water, running water, electricity and telephone.
I have my duties about the house. I must go shopping. I help my Mother to clean the rooms. It' s not difficult for me. I like our home to be clean and tidy.

I like to listen to modern music, but sometimes I like to listen to some classical music. My favourite composer is Tchaikovsky.

I like fresh air and exercises, but I have not much time to go in for sports. Перевод:)
