The Internet - the phenomenon ambiguous. It is bad that has no borders! That is, it doesn't protect teenagers from substandard information which children absolutely have no need to know. Along with useful information and positive communication, there are clubs of addicts, suicides, terrorists, the pornography sea that constitutes huge danger to teenagers at whom moral values aren't created yet, and thirst for "adult" entertainments of a bike. Special danger to the child consists in possibility of his involvement through social networks in extremist groups, the destructive religious organizations, whose activity is directed on commission antisocial, illegal, including penal acts.

Today I'd like to tell you about my favourite kind of sport and about my attitude to sports in general. They say, a sound mind in a sound body. I agree with this statement and I think it's absolutely true. You can never be a happy person if your health is poor. Sport is the thing that helps you not only to be strong, but also to remain healthy and happy. It also helps you to feel better and fills your life with positive emotions. – Сегодня я хотел бы рассказать вам о моем любимом виде спорта, о спортсмене, которым я восхищаюсь, да и о моем отношении к спорту в целом. Есть пословица: «В здоровом теле — здоровый дух». Я с ней согласен и думаю, что это абсолютно верно. Вы никогда не сможете быть счастливым человеком, если вы болеете или если у вас проблемы со здоровьем. Спорт — это то, что вам быть не только сильными, но также здоровыми и счастливым. Спорт также улучшает самочувствие и наполняет вашу жизнь положительными эмоциями.
