Dear Paul,
How are you? Thank you for your letter. Last time I promised you to tell about my
school. So, this year I’m in the sixth form. We have got some new subjects, for example
Geography which I like very much, so we’ve got more lessons every day.
As I wrote last time we have lunch from 12 o’clock to 12.20. Some pupils eat in the
canteen but I like bringing my own lunch because my mother makes great sandwiches.
Now we’ve got 5 or 6 lessons every day so we’ve got a lot of homework and it takes us
several hours to do it. Sometimes we have to sit up to write a composition, to prepare a
report or to learn a poem by heart. As I like Ukrainian Literature I read a lot too.
I’m interested in foreign countries, their culture and peoples so the subject I like most is
English. We have very interesting English lessons because our teacher trains us in
different ways. We learn new words, dramatize texts and dialogues, discuss interesting
things, do role-plays, listen to tapes and speak a lot. Our teacher usually supports us when
we work in pairs and make up our own conversations.
Are things very different at your school?
Best wishes,
Fred.
