Задайте как можно больше вопросо к тексту. Leisure
When we have time for leisure, we usually need something that can amuse and interest us. There are several ways to do this.
People use radio or television. They switch on the radio set or TV set and choose the programme they like best. Some people like music. They listen (o various concerts of modern and old music, new and old songs, and see dances. Those who are fond of sports listen to or watch football and hockey matches. These are the most popular kinds of sports. There are a lot of fans among people. They can also see championships in athletics and other kinds of sports.-Everybody likes to see skating and dancing on the ice. Radio and television extend our knowledge about the world in which we live. Television helps us to 'visit' different lands, see new plants, animals, unusual birds, fish and insects, mountains and valleys, lakes, rivers, and seas. We are shown different countries, cities and towns and people who live there. On TV people could even see both sides of the Moon. This is what we can do at home.
If we want to go out, there arc a lot of cinemas, theatres, museums, Houses of Culture and clubs in our country where we can spend our free time.
In big cities like Moscow and St. Petersburg it is often difficult to decide where to go in the evening. Newspapers tell us what is on at cinemas and theatres. If you are a theatre-goer, you will choose a play you want to see. If you are a film fan, you will go to a cinema. When new interesting plays are on. it is not easy to get tickets, because the theatres play to full houses every night. Then you must book tickets.
In small towns and villages they have no actors of their own. So they invite a group of actors from a big town or a city to show plays. Everyone likes to see the plays. Schools usually get tickets for their pupils. They go to the theatre with their teachers and have talks about the play they have seen.
The cinema has really become the most popular kind of art. Films are shown in cinemas, clubs. Houses of Culture and even schools in villages. Young and old people like to see films very much, and when a good film is on, the house is usually full.
In small towns and villages both Houses of Culture and clubs are the centres of cultural activities which are carried out through different sections. Those who like to dance join a dancing section. Those who are interested in music join a musical section where they are taught to play different musical instruments. People who are fond of sports can join sport sections, such as football, skiing, boating, chess, and others. The art section is one of the most popular with the people, because they can learn to create beautiful things there. Some members are taught to paint, and they organize local exhibitions of their paintings. Some do cutting work, others grow flowers and take part in town and region flower-shows.
Old traditions are coming to life. In some villages they build 'Huts on hen's legs', taverns in the old Russian style such as 'Lubava' on the way from Moscow to Novgorod, where people can meet their friends, have pleasant talks, eat Russian food and listen to Russian music.
So you can see how interesting are the ways in which leisure time can be spent.
