Помогите написать письмо на тему: Марка пригласили в аквапарк, а он не умеет…

Dear Mark,Many thanks for your letter. It was lovely to hear from you after such a long time. You asked me if it's difficult to learn to swim. No. It isn't difficult as you think. You know it's very enjoyable. I love swimming and I have started swimming since I was three years old. So I am the best swimmer and you can count on me. I will teach you to swim. Don't be afraid of that. I'm looking forward to seeing you soon and to spend weekends together. By the way what is your favourite sport? When have you started? Why did you prefer that one? Best wishes,Tim
