Television and volunteer camps

Kinds of programmes: scientific, educational, nature, sports, music, comedy, cartoon and news. Likes and reasons: “I like nature programmes because I learn about animals.” TV history: television was not made by one person but by many scientists. In 1884 Paul Nipkow of Germany made an early system for sending pictures; in the 1920s the Scot John Baird showed a working television system; black-and-white pictures later became colour. In 1969 hundreds of millions of people watched astronauts walk on the Moon from their homes. To ask about history we use the Past Simple: “When did colour TV appear?” — “It appeared in the 20th century.” Talk about pros and cons: a little TV is fine, but too much hurts our eyes and takes time from other activities.
