Задание 1. Read the text: A computer for Scuba Divers

A computer for scuba divers will provide in one device information about time, depth and air supply. It is to be used together with special divers’ tables. A display will provide visual information and audible warnings about critical conditions.

If a diver wants to know an accurate depth he is down, he must set water type he is in the sea, he will set “sea water”, otherwise he will set “fresh water”. The device shows the diver’s current depth in meters and the level of power left in the batteries. It will indicate if the level is low, medium or high.

If a diver wants to know how long he has been down, he can see this from the display. If a diver needs to spend some minutes at a certain depths for decompression, he will start his stop watch, and will wait until the time has elapsed (passed). If a diver wants to know the amount of air left in the tank, he can see this from the contents display.

A warning signal tells him when he must start his ascent. Before he descends, the diver sets the time to ascent. If he began his ascent before the display started flashing, he would be within safe limits. If he did not ascend then, he would expose himself to decompression sickness. If he started his ascent and went up too quickly, he would see a warning light “Too fast”. Then he should slow down his ascent.

Задание 1. Read the text: Television

The television set is evidently the most important and popular electronic product of all time. All homes in developed countries have one or more TV sets and in many countries there are considerably more TV sets than telephones. But in 1939 at the World’s Fair in New York a tiny nine-by- twelve inch box was the centre of attention for hundreds of people. They were the first to see a television set in action. Compared to today’s TV shows of underwater and outer-space research, those first black-white pictures were not very good. The pictures were only transmitted from one side of the Fair territory to the other. But in 1939 they were of historical importance. Within a few days the news of television spread throughout the world. A lot of people wanted to have a look at the new invention. Everyone was interested in it. But only few people owned television sets in the next few years. When World War II broke out electronic factories that began the TV production stopped making them and started making war materials instead. When the war was over, TV sets began coming off factory assembly lines. By 1958 there were millions of them.

In a surprisingly short time people watched fewer and turned from newspapers and magazines to TV. In its short history television has had great influence on people’s life and way of thinking. Rocket-launching, concerts and football and tennis matches can be seen direct as they occur. The boundaries of time and space have disappeared.

At present TV communication is provided with the help of a system of artificial earth satellites so that people living in different parts of the country and all over the world and in different time zones are able to watch the central TV programs at the most convenient hours. Nowadays many countries also have cable TV, a system using wires for the transmission of television programs (like telephone calls). Cable television first appeared in 1949 as a means of transmitting TV signals to rural and mountain areas far from big cities. Cable television’s next big step forward was made by the mid — 1980s. Scientists announced that many technical problems had been solved and in the future it would be possible via satellite and cable TV to use more channels on a TV set at every home in the world. Then we saw how a new technical invention, colour television, was rapidly replacing black-and-white television. Recently it was reported that the first pocket-size colour television set had been developed. It was stated that a liquid-crystal display was used similar to those on calculators and watches and that it weighed less than a pound.

A few years ago it became evident that the next major advance for TV would be digital television. In a digital system the usual continuous signal is replaced by a digital code containing detailed information on brightness, colour, etc. A digital TV set hangs on the wall like a picture. Essentially, it is a minicomputer with a visual display. Once a week you put the programs you like into the memory, and the TV set will automatically switch on the desired channel at the right time. You can watch several programs simultaneously on mini screens and then produce one of them in full format. Also, the TV set can automatically video-record the programs when you are absent or occupied.

By the end of 1980s television has moved to a new and the most important stage in its development since the appearance of colour television. Technically it is called high-definition television (HDTV) or Hi-Vision. This is the much higher resolution television of the 21st century.
