Культура общения — распространённое в советской и российской лингвистике понятие, объединяющее владение языковой нормой устного и письменного языка, а также «умение использовать выразительные языковые средства в разных условиях общения». Этим же словосочетанием обозначается лингвистическая дисциплина, занимающаяся определением границ культурного (в вышеприведённом смысле) речевого поведения, разработкой нормативных пособий, пропагандой языковой нормы и выразительных языковых средств.

Ive been wanting to learn how to play football. But unfortunately I did not have a soccer ball. With the kids in the yard, we could only play when he left to walk my friend Sergei. He has a brand new classy goal. Serega too, like me, loves football. We are in early childhood with dreams of becoming professional footballers. Trained your body: jogging in the morning, swinging horizontal bar, practiced interesting moments. We are in a sports store bought with other football shape our favorite team ...Together with Sergey we watch all the TV mast, a cheer for our favorite team. Very happy when they win, and very upsetting their loss. Football - This sports game, which disciplines, brings the power of will and endurance, it is played only a very brave and strong. Even if for some reason I can not become a professional footballer, my current hobby necessarily help me to grow up strong, brave, sturdy. This is a wonderful hobby that brings not only pleasure but also tempers my health.
