Dear Mike,

Thank you for your letter. Sorry l haven't written for long I was busy at school.

In your previous letter you asked me about my favorite subject. So, l am sure that my favorite subject is English and I am really fond of foreign languages. I really enjoy read and translate different tasks, find out new words and learn them. Unfortunately l hardly can find time for English because l have a lot of homework every day and it annoy me! However l have some free time. I usually play football with my friends or read books.

How many Maths lesson have you got?

Have you got any problems with another subject?

Do you miss friends from your old school?

Write soon,
