Сжелайте пожалуйста. Надо написать письмо используете если можно имя Саша)

Dear Ann,
Thank you for the letter I received yesterday. I was glad to hear from you again.
You asked about my favourite subject. Well, I think biology is the most interesting because I’m really keen on structure of the different organisms.
That’s all for now. Write back soon.
With love,
Sasha
