Electricity It is impossible to imagine our civilization without electricity: economic and social progress will be turned to the past and our daily lives completely transformed. Electrical power has become universal. Thousands of applica tions of electricity such as lighting, electrochemistry and electro metallurgy are longstanding and unquestionable. With the appearance of the electrical motor, power cables re placed transmission shafts, gear wheels, belts and pulleys3 in the 19-th century workshops. And in the home a whole range of various time and labour saving appliances2 have become a part of our ev eryday lives. Other devices are based on specific properties of electricity: electrostatics in the case of photocopying machine and electromag netism in the case of radar and television. These applications have made electricity most widely used. The first industrial application was in the silver workshops in Paris. The generator — a new compact source of electricity — was also developed there. The generator replaced the batteries and other devices that had been used before. Electric lighting came into wide use at the end of the last cen tury with the development of the electric lamp by Thomas Edison. Then the transformer was invented, the first electric lines and net works were set up, dynamos and induction motors3 were designed. Since the beginning of the 20th century the successful develop ment of electricity has begun throughout the industrial world. The consumption of electricity has doubled every ten years. Today consumption of electricity per capita4 is an indicator of the state of development and economic health of a nation. Elec tricity has replaced other sources of energy as it has been realized that it offers improved service and reduced cost. One of the greatest advantages of electricity is that it is clean, easily-regulated and generates no by-products5. Applications of electricity now cover all fields of human activity from house wash ing machines to the latest laser devices. Electricity is the efficient source of some of the most recent technological advances such as the laser and electron beams. Truly6 electricity provides mankind with the energy of the future.

Найдите предложения со словами to have, one, that, пере ведите. Although the US is a large country with many peoples the lan guage is almost the same wherever one goes. There are two reasons for this. One is that people move around a great deal in the US. A man can grow up in one part of the country, go to college in an other place, find work in another place and marry a girl from still another part of the country. The second important factor is public communication. Movies, radio and television all have standard way of speech. The southern part of the US is probably the region with the most individual speech. Southern pronunciation differs from that in the rest of the country. Southerners talk slowly and often do not pronounce «г» or a final «g». Another common Southern expression is the unusual use of the word «evening». In most parts of the country this means the time after the sun goes down, the early part of the night, but to a Southerner it can mean any time after twelve o’clock noon. In the southern mountains there have not been new settlers from other countries for two hundred years. They have ways of speech that are like the English spoken centuries ago when the first people came there from England. Many songs they sing today are those sung long ago in England. Упражнение 18. Поставьте глагол to be в соответствующей форме. Today is ..., ..., 20... I ... at my English class. I ... reading a story about Thomas A. Edison.

Before Faraday’s inventions in the field of electricity and mag netism the only source of electricity that was used was the galvanic battery. It made possible some practical applications: the electric light and electric telegraph. The practical use of electricity on a larger scale became possible after developing electromagnetic ma chines, generators and transformers. It is considered that the devel opment of the induction motor has become the most important technical achievement. At first, the induction motor had a constant and unchangeable speed (скорость). Some years later a motor with two speeds was designed. Since its invention the induction motor has been considerably improved and its power increased. But the principle of operation still remains the same. CONVERSATION Exercise 1. Answer the questions.

Just today I’ve begun some im portant work. Oh, excuse me, meet my assistant John Smith. John, this is my old friend from my home town, Ben Wilson. Smith: How do you do, Mr.Wilson? W: How do you do, Mr.Smith? Glad to meet you. Ed.: Will you come to my laboratory and have dinner with John and me tonight? W.: Yes, I will. Ed.: Come at six tonight, will you? W.: I’ll certainly come. 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.

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 your studies», his father replied. «Where did the car hit him?», asked the coroner (следователь). «At the junction (стык, перекресток) of the dorsal and cervial ver tebrae (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». Text 3B Прочитайте текст. Ответьте на вопрос, почему Эдисон сказал: «Don’t watch the clock». 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 in ventions. 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. Text 3C |
