Read the text “Summer and winter sports”.

People all over the world are very fond of sports and games. That is one of the things in which people of every nationality and class are united.

The most popular outdoor winter sports are shooting, hunting, hockey and, in the countries where the weather is frosty and there is much snow — skating, skiing and tobogganing. It's so nice to go to the skating-rink on a frosty sunny day. Some people prefer to be out of town in such weather and to sledge or to ski in the woods. Many people greatly enjoy figure-skating and ski-jumping.

Summer affords excellent opportunities for swimming, boating, yachting, cycling, gliding and many other sports. Among outdoor games football takes the first place in public interests; this game is played in all the countries of the world.
