At six o'clock at the laboratory.

W.: Good evening, Tom. Good evening Mr. Smith.

S.: Good evening, Tom. Good evening Mr. Wilson. Mr. Edison is

experimenting with a microscope. All his interest is there.

Would you mind walking around for a while looking at Mr.

Edison's inventions.
W.: With pleasure.
S.: In a few minutes dinner will be brought. We usually eat our

dinner here. Don't you mind? W.: Certainly not.

S.: The dinner is ready. Let Mr. Edison know you are here.

W.: Shall we eat, Tom? But he doesn't answer.
S.: He is busy working with his microscope.

W.: But I am quite hungry. Tom, the food looks good, and it is

getting cold.
S.: You see, Mr.Edison never stops working for a second till he

is satisfied with what he is doing. W.: Then let's sit down and eat.

Two hours later Mr.Wilson and Smith finished eating and left the laboratory

Ed. (entering the laboratory): Oh, I am hungry. If those dishes were

not empty, I'd say I've had no dinner tonight. Exercise 4. Speak about:

1. Electricity itanature history and development.

2. Applications of electricity cover all fields of human activity.

Use exercises 1,2, as well as the following words and word combinations for your topic: it is difficult to imagine; applications such as; completely; to replace; to come into wide use; to double every ten years; to be an indicator; the latest technological advances. Exercise 5. Read and smile:

A young doctor, the son of a well-known professor of medicine, proudly (с гордостью) told his father one day: " Imagine, dad! I've cured (выле­чить) that lady that has been your patient for ten years".

"She deserved (заслужить)it. It was she who had paid for vour studies," his father replied.

"Where did the car hit him?", asked the coroner (следователь). "At the junction (стык, перекресток) of the dorsal and cervial vertebrae (спинных и шейных позвонков)", answered the doctor. A big man rose from his seat. "Listen, I've lived in these parts for fifty years", he protested, " and I've never heard of this place."

A Great Citizen of the World

Every day many people visited Thomas A.Edison's laboratories in Orange, New Jersey. Some of them were young inventors who went to study, but many more of them were tourists. They came from all parts of the US and from other countries as well.

One day a very important citizen from England visited Edison's factories, taking with him his young son.eight years old. They spent many hours in great workshops, looking at hundreds of useful inventions.

Before leaving the laboratories the man went to the office of the main building. Giving his card to the person in charge, he asked: "May I speak to Mr.Edison, please?". The man looked at the card and then answered: "Wait a minute, I'll see". Soon he returned and said: "Come this way, please. Mr.Edison will see you."

The father and his son went into the great inventor's workroom. "Mr.Edison", said the Englishman, "I brought my young son here to see what the world's greatest citizen has done. I want this day to help him all his life. Will you please shake hands with him and say something that he

will remember?"

Mr. Edison took the boy's hand. He laid his other hand on the child's shoulder and looked into his eyes. "My boy", he said, "don't watch the

clock."

In 1928 Mr. Edison was eighty-one years old, but he still worked

sixteen hours a day.

TEXT3C

Прочитайте текст. Расскажите по-английски о преимуществах солнечной энергии в качестве источника электричества.

Solar Light by Night Most people living in towns consider it a usual thing that streets are lit at night. But street lights need a power supply (источник энергии) therefore distant areas with no source of electricity remain in darkness until the sun comes up again.

With new appliances now offered by several British firms, many distant places could be lit with solar-powered street lights. It may seem strange that the lamps can use the power of the sun which shines by day when the lamps are needed at night, but they work by using energy accumulated during the day from a solar panel. The solar panel produces electricity which charges (заряжать) a battery. When the sun goes down the battery power is then used for lighting. Each lamp has its own panel so the system can be used for one individual light or a number of them.

In the south of Saudi Arabia a motorway tunnel miles from any power supply is lit day and night by solar-powered devices. The solar panels provide power during the day and charge batteries which accumulate enough power to light the tunnel at night. The generation of electricity oy batteries is still expensive but the advantage of sun-powered lamps is that they can bring light to areas distant from any other power supply.

There is one more advantage of solar power: not only it is unlimited, but also its use does not pollute the environment. That is why it is very important to develop devices which make it possible to transform solar power into mechanical or electric forms of power.

Non-traditional Renewable Sources of Energy

It is known that much is being done in the world today for the development of non-traditional sources of energy. Without them the Earth cannot support its present population of 5 billion people and probably 8 billion people in the 21-st century.

Now we are using traditional power sources, that is, oil, natural gas, coal and water power with the consumption of more than 50 billion barrels per year. It is evident that these sources are not unlimited.

That is why it is so important to use such renewable sources of energy as the sun, wind, geothermal energy and others. Research is being carried out in these fields.

One of the most promising (перспективный) research is the development of power stations with direct transformation of solar energy into electricity on the basis of photoeffect. It was Russia that was the first in the world to develop and test a photoelectric battery of 32,000 volts and effective area of only 0.5 sq.m., which made it possible to concentrate solar radiation. This idea is now being intensively developed in many countries.

However, the efficiency of a solar power station is considerably reduced because of the limited time of its work during the year. But it is possible to

improve the efficiency of solar power stations by developing different combinations of solar power stations and traditional ones - thermal, atomic and hydraulic. Today some engineers are working at the problem of developing electric power stations with the use of a thermal-chemical cycle. It will operate on products of the transformation of solar energy, whereas the "solar" chemical reactor uses C0₂ and water steam of the thermal power station. The result is that we have a closed cycle.

In Kamchatka there are geothermal power stations operating on hot water-steam mixture from the depths of about a kilometre. In some projects water will be heated by the warmth of mountains at a depth of four - five km.

It is planned that plants working on the energy of the solar heat provided by the sun will be built on a larger scale.

That different wind energy plants are being developed is also well-known. These energy plants can be small (of several kilowattes) and large powerful systems.

It is important that all these advances in developing new sources of energy and improving the old ones help to solve the energy problem as a whole and they do not have negative effects on the environment.
