Вот сам текст !
My alarm clock rings at 7.30am. I get out of
bed, and go to the bathroom. I have a quick
shower and then I get dressed. We wear a
school uniform at my school, so I don’t have
to choose what to wear! I go downstairs and
have breakfast – usually juice, cereal and
toast – with my mum and dad.
After breakfast, I brush my teeth, quickly
check my email and then put my books in my
bag. I usually ride my bike to school, but if the
weather’s bad, my mum drives me. I get to
school at 8.45.
The first lesson starts at nine o’clock.
Lessons last for 40 minutes. We have a
twenty-minute break from 11 to 11.20. During
the break, my friends and I usually play in the
playground, and we sometimes buy snacks
from the vending machine.
At 12.40, we have lunch in the school
canteen. Some kids bring their own
sandwiches, but I buy a hot meal.
We have three more lessons in the afternoon,
and then at half past three we either do sport
or activities. On Mondays, Wednesdays and
Fridays we play football, and on Tuesdays
and Thursdays we have clubs. I’m in the
photography club. It’s great fun!
I go home at half past four. I do my homework
first, then I write my blog and check my email.
I spend about an hour or two online most
days. Sometimes I send text messages to my
friends too.
I have supper with my mum and dad at about
half past six. After supper, I chat with my
friends online, or play with my neighbours
outside, or watch TV, or read a book.
On Thursdays, I go to a dance class
from 7.30 to 9.30.
I go to bed at about 9.45 most nights,
but I read in bed – or send text messages –
before I go to sleep.-
