Текст на тему любимый вид спорта,на английском языке три предложения,для девочки.
My favorite sport is tennis. I guess that it is very useful to play tennis for health. I have been playing in it for few months, and I happy that decided to go there.
Давайте уберем мелкие неточности. Начиная со второго предложения: I guess it is very BENEFICIAL for health to play tennis. (Useful в данном случае совсем не походит). I have been playing it (предлог in не нужен)... and I AM happy that I decided. А в остальном неплохо :)
