Question

Помогите, пожалуйста!даю много балов. английский язык 9кл. Television. Television is a way of sending sound and pictures through the air. (1) ___________ Although John Logie Baird was the first to show how television worked, his success was based on work by many other scientists from all over the world. (2) __________ The first television service opened in 1936 in Britain. Colour television began in the United States in 1956. At first, all television was black and white. Few people owned television sets because they were very expensive. (3) ______________________________________ Television works by changing light waves into electric signals. This happens inside the TV camera. A picture of what is happening in front of the camera forms on a special behind the lens. Behind the screen is an electron gun. (4) _____________________ It moves from left to right to cover each part of the picture. Each part is turned into an electric signal which is made stronger, then sent to the transmitter as radio waves. They are picked up by home TV antennas and changed back into electric signals. (5)________ The TV screen is covered with tiny chemical dots. In a colour set, these are arranged in groups of three: one red, one blue, one green. At the back there are other electron guns. These fire a beam of electrons to scan the screen just as the camera gun does. As each electron hits the screen, it lights up a dot. (6)___________ You do not see lines of coloured flashing lights, because the electron gun moves too fast for the eye to follow. What you see is a picture of what is happening in the television studio. (7)___________ Most programmes are recorded on film or videotape and sent out later.

Answer 3

Sure, I'd be happy to help you fill in the blanks for the text about television:

(1) Television is one of the most popular forms of entertainment in the modern world.

(2) The first television service opened in 1936 in Britain, but its success was based on the contributions of numerous scientists worldwide.

(3) Television works by changing light waves into electric signals inside the TV camera. A picture forms on a special screen behind the lens, and there is an electron gun behind the screen.

(4) The electron gun scans the picture from left to right, converting each part into an electric signal. These signals are then strengthened and transmitted as radio waves to be received by home TV antennas.

(5) The TV screen is covered with tiny chemical dots, typically arranged in groups of three (red, blue, and green) in color sets. At the back of the screen, there are other electron guns that fire a beam of electrons to scan the screen, lighting up each dot as they hit it.

(6) The fast movement of the electron gun prevents the human eye from perceiving individual flashing lights, resulting in a cohesive picture on the TV screen.

(7) Most television programs are recorded on film or videotape and broadcasted at a later time.
