Some of my friends think it's important to do sports regularly, while others would rather watch a sporting event on TV.
Nowadays people have to work more and they prefer to rest more actively Therefore they need better health, more energy and endurance in order to carry out all activities efficiently and without fatigue. It's important to be in good shape and to stay healthy and attractive.
To my mind, physical exercises are essential for everyone. If you want to be strong physically and mentally, you can go to a fitness club, a sauna or a swimming pool. Physical exercises strengthen the immune system, improve mental health and help prevent different diseases and obesity. Exercising is also the best remedy for insomnia, depression and stress.
However, a lot of people say they have neither time nor opportunity to go in for sports. What is more, they feel too tired after a hard day's work. That is why all they can do in the evening is to watch sporting events on TV. But I think that if you don't have an opportunity to go to a fitness club, you can just buy a treadmill or a stationary bike and exercise at home. You can also do your morning exercises, jog, swim in summer, ski or skate in winter, play different sports games such as tennis, football, volley-ball, basket-ball and so on. At least you can dance and jump about your room to music for 10-15 minutes each day.
To conclude, if you want to be slim and strong, you must leave your comfortable armchair and exercise. It is not enough to watch other people doing sports. Only regular exercises will help you make your life longer and healthier.-

Чудеса
Однажды в июле Вили
(На солнце- И в сети
по сорок) Зеленое солнце
Вдруг выпал Залаяли птицы,
Оранжевый снег Запели собаки...
на пригорок Я вас уверяю,
И в небо над лучом Что это не враки.
Привычно и ловко Зажмурив глаза
Взлетела коровка, Я улегся на луг,
Как божья коровка. И столько чудес
А бабочки Приключилось
Гнезда из прутиков - вокруг-
