Дорогая Эмилия,  
за твое письмо. Было замечательно прочитать о твоем новом доме. 
Что касается моей новой школы, она очень большая! В ней есть три компьютерных класса и замечательные спортивные объекты.  Действительно, она - прекрасное место, и я люблю учиться в ней. Дети в моем классе очень дружелюбны.     
Я уже завела некоторых новых друзей и часто встречаюсь с ними после уроков.                     
В этом году у меня есть только один новый предмет. Это - экономика, и я начинаю в конце-концов думать, что она не трудная!
Между прочим, какими музыкальными стилями ты наслаждаешься? Есть у тебя любимые группы? Хотела бы ты сходить на их концерт? Что касается меня, я предпочитаю Radiohead. Они прикольные!
Мне надо идти сейчас.  
С большой любовью,
 Энн
Dear Emily,  
Thank you for your letter. It was great to hear about your new house. 
As for my new school it's very big! It has three computer rooms and wonderful sport facilities. Actually, it seems a nice place and I enjoy studying there. The kids in my class are very friendly.   
I've already made some new friends and often meet after classes.                     
I've got only one new subject this year. It's Economics and I'm beginning to think that it's not difficult, after all! 
By the way, what music styles do you enjoy? Have you got any favorite bands? Would you like to go to their concert? As for me, I prefer Radiohead. They are cool!
I'd better go now. 
Lots of love,           
 Ann
