Вот пример письма по английскому языку на тему, указанную в задаче:
Dear Friend,
I hope you are doing well! I want to share my feelings about my brother's dangerous hobby — mountain biking. Although it's exciting, I often worry about him. I wish he would spend more time at home and choose a safer activity instead.
In my country, indoor sports like basketball and table tennis are very popular among teenagers. Many teens also enjoy playing video games and participating in dance classes. Teenagers often do extreme sports like mountain biking because they seek adrenaline and adventure. As for me, my favorite sport is swimming because it is fun and relaxing.
Take care!
Best wishes,
[Your Name]
