The text itself (the children need to translate some elements from Russian into English):
Last summer, Vadim and his family went on an amazing journey to the mountains. They проснулись early in the morning because they didn't want to упустить поезд. Vadim's little brother Sasha was so excited that he надел his shoes backward! They ran to the station and поймали поезд вовремя.

The train was быстрый and shiny, like it was made of серебро. Vadim sat by the window and played Minecraft. His маленький брат listened to Morgenstern and danced in the train. Meanwhile, quadrobbers бежали behind the window.

But then something strange случилось. A man in a золотой шляпе stood up and объяснил that he забыл his багаж at the airport. He looked very грустный. Vadim's dad, who is very добрый, gave the man some money to take a taxi back. The man thanked the family and вышел из поезда at the next stop.

Later, Vadim and his family found out that the man was actually a famous singer – Kanye West! He отправил them билеты to his concert as a thank-you gift. The concert was дорогой, but they visited it for free!

When the family прибыли at the mountains, the sun сияло brightly, and the air was fresh and cool. It was the best journey in their life!
