Hi, my name is Marina Smirnova. I'm 12 years old and I live in the beautiful city of St

Petersburg. My daily routine is typical of most students my age.

I get up at 7:00 am and after a quick breakfast I walk toschool. School starts at 8:00 am and

finishes at 2:00 pm . My favourite

lessons are History and Maths. They are both very interesting. We have many exciting things to do at school

after classes. On Tuesday and Thursday I have guitar lessons.

After school I go home . We always have

lots of homework. Around 6 o'clock in the

evening, I have dinner with my family.

After dinner, I usually watch TV.  Sometimes I play

a game of chess with my father. Most nights I go to bed at 10:30pm and read for a while

before I go to sleep.
