Кто может проверить текст на ошибки, без переводчика пожалуйста
In recent years, the sport has become
more popular. In our city as more and more people prefer to sport than bad
habits. Many people attend a fitness center and swimming pool.
Someone engaged in running, riding a bicycle. In winter, most people seek in
the woods to go skiing. And go skating at the stadium. Since winter is long in
the Urals, so skiing and skating are the most popular in our city.

Sport does very good and useful. In
the first place, because the sport is our life, it helps us not just sit and
move and live. We spend a lot of time in front of computer and TV, we
go on transport. So I think that should do sports everything from the smallest
to the elderly. Sports and improves health mood. This is an activity that
occupies your free time; as well you can meet new people.

Sport for me is all life, luck and
everything else I do only volleyball. And as I prefer winter skate.
