Краткое содержание

Принципы:

  1. Фокусируйте внимание на контенте, имеющем для вас какое-то значение
  2. Используйте язык как средство для коммуникации начиная с первого дня
  3. Если вы сначала поймёте то, что вам хотели сказать, то вы начинаете овладевать языком бессознательно (comprehensive input)
  4. Изучение нового языка - это также тренировка тела (правильное произношение зависит от мышц)
