Hi,John!
I apologize for not replying to you. I didn`t because I`m busy with studying.  I`m preparing to the exams. We`re having English,Russian and Maths exam. I think the most difficult exam is maths exam. But i do my best to prepare to it. It`s very important for this moment.
You know, I`m going to England after the exams to practice the English language. But I worry it`ll be difficult to adapt to Englishman`s life. But anyway, I`m sure it`ll be a wonderful experience in my life. People should develop their skills, and i think I`m not an exception. Could you be kind to tell me what difficulties i can expect in England?
With the best wishes, ...

I'd like to tell you about my summer holidays I spent in Sochi. It was just three years ago. My parents and me were sitting in the living-room discussing our plans for the summer holidays. My father suggested that we should go to Sochi. On hearing that I jumped up with joy and said it was a wonderful idea. My mother wasn't against the idea either. So one summer morning we started for our journey to Sochi.
My father showed us the famous Botanical Gardens, we went for hikes in the mountains, we saw the magnificent Augura Waterfalls. The sea was nice and warm. The weather was fine. When it was time to go home, we were sorry to leave the marvellous town of Sochі.
