It was Sunday so I didn’t have to go to school. I woke up late, got up and WENT to the kitchen.
It was strange but I COULDN’T find our cat, Tom, anywhere. The whole family got worried.
“He’s gone hunting,” my YOUNGER sister said. 
“All cats hunt MICE. I read about it in a book.”
“I’m sure he IS SLEEPING in the armchair,” Mum said. But the cat wasn’t there either.
“Look! I HAVE FOUND him!” my little sister shouted. “He’s in the washing machine!” We watched in surprise as the cat got out of the washing machine.
“Come on, kitty, come here. We WILL  GIVE you some milk.”

My favorite hobby is running. I enjoy running every time. When I run feel the wind and the air that surrounds me. Running is a very useful sport not only in terms of health but also psychologically. In addition to running, I also do other sports and enjoy them. A healthy lifestyle is very important to me. But there are some Hobbies / sports that I don't like to do such as swimming, Boxing, Football , Drawing and Gardening

Объяснение:

Мое любимое хобби-бег. Мне нравится бегать каждый раз. Когда я бегу, я чувствую ветер и воздух, который меня окружает. Бег-очень полезный вид спорта не только с точки зрения здоровья, но и психологически. Помимо бега, я занимаюсь и другими видами спорта и получаю от них удовольствие. Здоровый образ жизни очень важен для меня. Но есть некоторые хобби / виды спорта, которые я не люблю делать, такие как плавание, бокс, футбол, рисование, и садоводство.
