Excursion to the Museum of Art, organized in the autumn vacation with our class teacher, personally was very useful for me. I learned a lot of new, interesting, and received great pleasure from communication with the beautiful. Before, I just never thought about the fact that the works created by artists, musicians, architects, too, as well as historical events can be a wonderful chronicle of the past and present of mankind, his thoughts, hopes, struggle for their future. How little I still know! After all, in order to read this record based on the works of various art forms, it is necessary to know at least in general terms, the history of art, to understand his expressive means. I really want to get acquainted with the architectural styles and learn more about what a painting, drawing and sculpture.
ПЕРЕВОД
Экскурсия в художественный музей, организованная на осенних каникулах нашим классным руководителем, лично для меня оказалась очень полезной. Я узнал много нового, интересного и получил огромное удовольствие от общения с прекрасным.  Раньше я просто не задумывался над тем, что произведения, созданные художниками, музыкантами, архитекторами тоже, как и исторические события, могут быть замечательной летописью и настоящего человечества, его дум, надежд, борьбы за свое будущее. Как же мало я еще знаю! Ведь, для того чтобы читать эту летопись по произведениям различных видов искусства, нужно знать хотя бы в общих чертах историю искусства, разбираться в его выразительных средствах. Мне очень хочется познакомиться с архитектурными стилями и больше узнать о том, что такое живопись, графика и скульптура.

Dear John,
How are you? Everything is fine with me I haven't written for a while but I've been realy busy! Are you preparing for Christmas? Have you already bought gifts for your family? What about me I recently went shopping. It takes me a lot of time. I bought a T-shirt for my brother and a vase for my mother because her last vase was broken by cat. I have no idea what can I to present to my father. A seller advised to buy a cap, but I not sure about it. Also I bought smth to you. If you haven't bought presents and don't know what to buy we'll go shopping together.
Take care of yourself.

Nick.
