What do you think about it? Why?
Exercise 6. a) Read and say what you think about tea and what it does for you:
The English know how to make tea and what it does for you. Seven cups of it wake you up in the morning; nine cups will put you to sleep at night.
If you are hot, tea will cool you off, and if you are cold, it will warm you up.
If you take it in the middle of the morning, it will stimulate you 'for further work; if you drink it in the afternoon, it will relax you for further thought. Then, of course, you drink lots of it in off hours (вільний час).
The test of good tea is simple. If a spoon stands in it, then it is strong enough.
6) Use the following phrases:
1. If you ask me, tea ...
2. If you want my opinion, tea ...
3. I entirely / quite agree with the idea that ...
4. That's exactly my opinion / that's exactly what I feel ...
5. I do not like tea because ...
Exercise 7. Read and smile:
A Fable from Aesop
While sitting together one time, a group of animals was discussing the popularity of the elephant. They all agreed that the elephant was the most popular animal in the forest, but none of them could give a satisfactory explanation of this fact. Yet they all had certain comments to offer.
The giraffe [d i'ra: f] said, "If the elephant had a long neck like mine, then it would be easy to understand his popularity. He would be the tallest animal in the forest".
The peacock (павич) said, "If he possesed my beautiful tail, it would be easy to understand. He would be the most beautiful creature in the forest".
The rabbit said, "If he could run as fast as I, it would be easy to understand. He would be the fastest animal in the forest".
The bear said, "If he was as strong as I, it would be easy to understand. He would be the strongest animal in the forest".
Suddenly the elephant himself appeared. He was larger and stronger than any of the other animals, and he was also superior in many ways. But he was always quiet and modest about his many accomplishments. This, after all, was the real explanation for his popularity.
An American lady got into a smoking carriage (вагон) where an Englishman was smoking a pipe.
She began doing everything to show him she objected to his smoking. At last, seeing that the man paied no attention, she said, "If you were a gentleman, you would stop smoking when a lady got into the carriage".
"If you were a lady", replied the Englishman, "you would not get into a smoking carriage".
"If you were my husband", said the American lady angrily, "I would give you poison (отрута)".
"Well," said the Englishman at last, "if I were your husband, I would take it".

Now most submersibles are connected with a support ship on the surface.This connection is an armoured cable measuring an inch or two in the diameter and weighing up to 10 tons and it transmits power and navigational commands to the submersible, as well as sends sensor data and television images back to the support ship. Cables allow submersibles to transmit data at a great speed, but they limit the гапрг of territory studied and have many disadvantages in operation.
Autonomous underwater submersibles can move freely. Controlled by on-board microprocessors or by acoustic signals transmitted by a ship on the surface, battery-operated submersibles can cover much greater areas. They can operate under ice and in very deep water. Such three-ton unmanned crafts can submerge to the depth of almost 20,000 feet and stay there for up to seven hours. High quality images of the ocean bottom can be transmitted to the support ship in three to four seconds (because of the slow speed - about 5,000 foot per second through a water - acoustic data transmission is much less quick than signals sent via cable which travel at the speed of light).
But even these most advanced submersibles have definite disadvantages: batteries are heavy, data transmission is slow and computer programs are primitive. Future submersibles may overcome those difficulties. Some may be propelled by nuclear power or by fuel cells (паливні елементи) that use oxygen from the sea water. Many of them will rely on signal-compression techniques to speed up acoustic data links. Computerized systems will enable some submersibles to repair damaged telephone cables or oil platforms. If research work in this field continues to expand at its present rate, the number of radically different kind of more efficient crafts will appear very soon.
Прочитайте текст і назвіть особливості сучасного рятувального засобу па воді і принцип його дії.
Even though we now have ships of a kind unknown in earlier centuries, we are still very far from mastering the sea. The Greek sailor who was shipwrecked (терпіти корабля) on his way home from Troy and the sailor of tomorrow whose nuclear-powered cargo ship might be on fire both face the same dangers. They may drown (тонути), and so they need to keep afloat. They may die, and so they need to keep themselves covered and dry. Rescuers (рятувальник) may never find them, and so they need to send signals.
The Greek sailor at the time of the Trojan war had only a small chance of survival (порятунок). The sailor of tomorrow has a greater chance, especially if the ship has one of the new rescue crafts on board.
One such lifeboat looks more like a flying saucer (тарілка) than a boat. Sailors on board a ship which is in trouble can get into the capsule, close the water-tight doors and operate the controls which drop the capsule automatically into the sea. Made of glass fibre (скловолокно) the capsule will float on the sea and will not be dragged down by the sinking ship. It will protect the men inside from explosions, fire and extreme cold. It has a thirty-kilowatt diesel engine and so can carry survivors to the coast. To help rescue ship and
aircraft to find it the upper part of the capsule is covered with a special orange paint which can be detected by radar. Each capsule is large enough for twenty-eight men.
Прочитайте текст і розкажіть по-англійськи, що ви дізналися про історію Грінвіча і його сьогодення.
Greenwich is on the river Thames, five miles from the middle of London, and its story is 2,000 years old. The first English people -the Saxons - were fishermen there and they gave Greenwich its name - "the green village".
You can still walk along the old Roman road in Greenwich park. But the river was the true road to the outside world for the Romans and for English kings and queens who later lived in Greenwich.
The King Henry VIII loved this place. He knew that England must be strong at sea. So two big shipyards were started at Greenwich and for 350 years the ships made there were the best in the world.
Many ships were lost at sea - their sailors did not know how to tell exactly where they were.
In XVII century astronomer Flamstead tried to find the answer. He worked in an Observatory on the high ground in Greenwich park. The walls of its big light-sided (неміцною) room shook when the weather was bad. But from it, with a telescope made by himself, Flamstead could look all round the sky. And he did look night after night for twenty years. Carrying on Flamstead's work a hundred years later, an astronomer called Harrison finally made a clock which told the time at sea and helped sailors to know where they were. You can see Harrison's clock, still working in Greenwich museum of the sea. Because of Flamstead's work every country in the world now tells its time by Greenwich time.
Every year a million people come to Greenwich to see its museums and palaces and its two famous ships: one old, one new. Both the big CUTTY SARK and the little GYPSY MOTH sailed through dangerous waters before they came safely back to their Greenwich home. At the end of the 1800's the CUTTY SARK was the fastest ship of its size. Carrying more than a million kilos of tea, she travelled the 25,000 kilometeres from China to England in only hundred days.
Next to the CUTTY SARK is the GYPSY MOTH - only 16.5 metres long, but full of newest equipment. Her captain Sir F. Chichester wanted his ship to sail as far and as fast as the CUTTY SARK. When he sailed round the world by himself in CYPSY MOTH in 1 966 -the first man ever do this-he took a flag from the CUTTY SARK with him.

Прочитайте текст і знайдіть абзаци, де йдеться про застосування лазерів. Переведіть.
In the "War of Worlds" written before the turn of the century H. Wells told a fantastic story of how Martians almost invaded our Earth. Their weapon was a mysterious "sword of heat". Today Wells 'sword of heat has come to reality in the laser. The name stands for light amplification by stimulated emission of radiation.
Laser, one of the most sophisticated inventions of man, produces an intensive beam of light of a very pure single colour. It represents the fulfilment of one of the mankind's oldest dreams of technology to provide a light beam intensive enough to vaporize the ^ hardest and most heat-resistant materials. It can indeed make lead run like water, or, when focused, it can vaporize any substance on earth. There is no material unamenable to laser treatment and by the end of 2000 laser will have become one of the main technological tools.
The applications of laser in industry and science are so many and so varied as to suggest magic. Scientists in many countries are working at a very interesting problem: combining the two big technological discoveries of the second half of the 20-th century - laser and thermonuclear reaction - to produce a practically limitless source of
energy. Physicists of this country have developed large laser installations to conduct physical experiments in heating thermonuclear fuel with laser beams. There also exists an idea to use laser for solving the problem of controlled thermonuclear reaction. The laser beam must heat the fuel to the required temperature so quickly that the plasma does not have time to disintegrate. According to current estimates, the duration of the pulse has to be approximately a thousand-millionth of a second. The light capacity of this pulse would be dozens of times greater than the capacity of all the world's power plants. To meet such demands in practice scientists and engineers must work hard as it is clear that a lot of difficulties are to be encountered on route.
The laser's most important potential may be its use in communica-tions.The intensity of a laser can be rapidly changed to encode very complex signals. In principle, one laser beam, vibrating a billion times faster than ordinary radio waves, could carry the radio, TV and telephone messages of the world simultaneously. In just a fraction of a second, for example, one laser beam could transmit the entire text of the Encyclopaedia Britannica.
Besides, there are projects to use lasers for long distance communicat-ion and for transmission of energy to space stations, to the surface of the Moon or to planets in the solar system. Projects have also been suggested to place lasers aboard Earth satellites nearer to the Sun in order to trans-form the solar radiation into laser beams, with this transformed energy subsequently transmitted to the Earth or to other space bodies. These projects have not yet been put into effect, because of the great technolo-gical difficulties to be overcome and therefore the, great cost involved. But there is no doubt that in time these projects will be realized and the laser beam will begin operating in outer space as well.

What makes a soap bubble (мильна бульбашка) rise and fall. If a soap bubble does not break at once, it will begin to fall. Why? To explain this we must remember a balloon which is filled with hot air. It rises for some time and then it falls again. A balloon rises because the hot air inside it is lighter than the air round it, and as it is lighter, it must rise. When the air inside a balloon cools, the weight of the balloon itself makes it fall. A soap bubble is really a little balloon filled with hot air. This air is much lighter than the air outside. It can carry the weight of the water which makes the skin of the soap bubble. But this can not last for a long time, because the skin of the soap bubble is very thin. The bubble becomes as cool as the air around it and it begins to fall. It is interesting to know that the early experiments with balloons were based on soap bubbles.

Те understand why light from the laser is so concentrated you must know that light travels in waves. Ordinary white light is made up of many wavelengths travelling in every direction. Laser light is essentially of one wavelength, with all the waves moving in one direction. Because the laser wavelengths intensify each other, they can remain in an unbelievably straight beam for a long distance. Almost any
substance can be forced to "lase" if you work hard enough with it. Gas lasers give off continuous beams of light. Tiny semiconductor lasers may be especially useful in computers for transmitting signals to replace the use of cables. Many lasers can give off invisible radiation, either infrared or ultraviolet.
