a) Radio and Electronic Devices.
b) Radio Waves.
c) The Birth of Radio.
d) Radio and TV.

1. Today we don’t think twice when we turn on the radio, but when a 21-year-old Italian invented it over 100 years ago no one could believe their ears.
2. One day in 1895 in Bologna, Italy, an Italian engineer sent the world’s first radio signal. Using a simple radio transmitter and a receiver, he sent a signal from his attic room to his brother who was hidden in a field a kilometer away. 1 _b__. The Italian government showed no interest in young Marconi’s invention, but his mother believed he had a good idea. So in February of the following year, she sent him to England to meet her cousin who was an important engineer. 2 _e _.
3. In England this engineer and his cousin were joined by two other inventors. In 1897 he formed the Wireless Telegraph Company in London and started to transmit simple radio signals over long distances. In 1899 he sent the first wireless telegraph across the English Channel to France.
3 __a _.
4. He had always believed that radio waves could travel round the curve of the earth. By 1901 he had improved his radio system so much that on 12th December he astonished the world by sending the first radio signals across the Atlantic Ocean. 4 _d__. His system was soon adopted by the British and Italian navies. From now on, his company had the monopoly of wireless communication and he became a multi-millionaire.
5. This engineer is one of the key figures of the twentieth century. He even recognized the military importance of radar and thought of the idea of sending radio signals out into space. When he died in 1937, wireless stations all over the world closed down for two minutes as a mark of respect. He made only one big mistake. 5 __c _.

IX. Translate paragraphs 2 and 3 into Russian.
Однажды в 1895 году в Болонье, в Италии, итальянский инженер отправил первый в мире радиосигнал. Используя простые передатчик и приёмник, он послал сигнал со своего чердака брату, который спрятался в поле в одном километре от него. Когда его брат получил сигнал, он выстрелил в пистолет. Итальянское правительство не проявило интереса к изобретению молодого Маркони, но его мать считала это хорошей идеей. Таким образом, в феврале следующего года она отправила его в Англию на встречу с её двоюродным братом, который был важным инженером. Это было путешествие, которое изменило мир.
В Англии к инженеру и двоюродному брату присоединились ещё два других изобретателя. В 1897 году он основал беспроводную телеграфную компанию в Лондоне и стал передавать простые радиосигналы на большие расстояния. В 1899 году он послал первую телеграмму через Английский канал во Францию. Они были отправлены из Полдху в Корнуолле и были получены через 3520 километров в Санкт-Джонсе, который находится в Ньюфаундленде, используя антенны, которыми управлял в воздухе бумажный змей.
