I would like to tell you about a great Maslenitsa celebration in Russia. It is celebrated on last Sunday of March, when winter is losing its rights and spring comes. On this day there are Russian great folk festivals with horses, getting a living rooster from the post, a lot of jokes, songs and dances. On the streets of cities, towns and villages different mummers walk, they offer everybody hot tea and Russian pancakes with different toppings: honey, jam, butter, eggs! But most importantly is the effigy of winter that is burnt  and everyone rejoices the beautiful spring coming. 

Я хочу рассказать о замечательном празднике Масленица. Его отмечают в последнее воскресенье марта, когда зима сдает свои права, и приходит весна. В этот день в России большие народные гулянья с катанием на лошадях, доставанием живого петуха со столба, шутками, песнями и плясками. На улицах городов и сел ходят ряженые, всем предлагают всем горячий чай и русские блины с разными начинками: медом, вареньем, маслом, икрой! Но самое главное, на площади сжигают чучело зимы и радуются наступлению красавицы-весны.

The school of the future is the kind of school that awaits us in a few decades. Most likely, the concept of the school will not change, the students will learn the material, take exams, enter universities, but how the school itself will look is a completely different question. The entire modern world is becoming more and more computerized and technological. Even now, schools are undergoing many changes that would have excited the minds of students half a century ago: electronic diaries, computer labs, projectors in every classroom, all exams are taken under cameras online, the entire education system is moving from a conservatory to the education system of the future.
