half past seven in the morning. I make my bed and go to the bathroom. I wash my
face and hands and clean my teeth. Then I go to the kitchen. The breakfast is on
the table. My Mum usually makes breakfast for me. Usually I have a cup of tea
with cheese burgers or sandwiches or juice with biscuits. After breakfast I go to
school.
My school begins at 8.30. I have 5 lessons every day. At school I study many
subjects: Russian, Maths, English, Geography, History, Physics, Chemistry,
Literature and others. I usually have (don’t have) lunch at school. After my lessons
I go home. At home I have dinner and a little rest. Then I do my homework.
In the evening I help my Mum, play with my sister (brother), watch TV, play
computer games or go for a walk with my friends.
I go to bed at 10 o’clock and sleep well all night.
