A) write an answer to the letter from exercise textdear mike, i am glad to receive your letter again. you wrote about russian winter joy: skiing, skating, sledging. frankly speaking, i have no idea of -eal snow. it never snows in my country! but we also had much fun during our christmas holidays.my schoolmates and i travelled to yellowstone national park! i think it's a journey of my life.we enjoyed hiking, camping, boating, fishing, you know, yellowstone became a national park in 1872 for its unique beauty and wildlife. there are many mountain lakes, canyons, rivers and mountain ranges in the park. we also had an opportunity to watch different species of mammals, birds and reptiles. by the way, i took many photos of endangered animals in their natural habitat. now i am thinking of taking part in one of the contests about wildlife held by the national geographic magazine.what about russia, have you got any national parks in your country? what are they famous for? how are endangered animals protected in russia? i am looking forward to hearing from you as soon as possible.best wishes, george
