Sure, here's a small story about Vika's friend in English suitable for a 3rd-grade level:
Vika has a wonderful friend named Anna. Anna is eight years old, just like Vika. She has curly brown hair and bright blue eyes. Anna loves to play outside in the park. Her favorite game is hide and seek. Every day after school, Anna and Vika meet at the big oak tree. They laugh and run around, having lots of fun.
Anna is very kind and always helps her friends. She likes to share her toys and books with Vika. On Saturdays, Anna and Vika go to the library together. They love to read stories about animals and adventures. Anna’s favorite book is about a brave little dog.
Sometimes, Anna visits Vika’s house and they bake cookies with Vika’s mom. Anna’s cookies always taste delicious. Vika and Anna are best friends, and they always make each other happy. They hope to be friends forever.
