Electricity is the p henomenon associated with positively and negatively charged part icles of matt er at rest and in motion, individually or in great numbers Since every atom contains both positively and negatively charged particles, electricity is connected with the physical properties and structure of matter and is an important factor in physics, chemistry and biology 1 Lightning is a naturally occurring electrical Electrical conductivity is an important of metals Atoms, which were once thought to be the smallest , are known to consist of even smaller ones , atoms have only a weak charge, but a very large number together can make a powerful charge Albert Einstein discovered the relationship between and energy Exercise 3: Match with the definition The branch of science and technology concerned with Energy a Current b Electronics c the design, building, and use of engines, machines, and structures A flow of electrical charge carriers, usually electrons or electron-deficient atoms An apparatus using or applying mechanical power and having several parts, each with a definite function and together performing a particular task The branch of physics and technology concerned with the Machine d design of circuits using transistors and microchips, and with the behavior and movement of electrons in a semiconductor, conductor, vacuum, or gas Power derived from the utilization of physical or Engineering e chemical resources, especially to provide light and heat or to work machines II READING COMPREHENSION Engineering Engineering is largely a practical activity It is the application of science and math to solve problems Civil engineering is concerned with making bridges, roads, airports, etc Mechanical engineering deals with the design and manufacture of tools and machines Electrical engineering is about the generation and distribution of electricity and its many applications Electronic engineering is concerned with developing components and equipment for communications, computing, and so on Mechanical engineering includes marine, automobile, aeronautical, heating and ventilating, and others Electrical engineering includes electricity generating, electrical installation, lighting, etc Mining and medical engineering belong partly to mechanical and partly to electrical Exercise 1: Complete the blanks in this diagram using information from the text Exercise 2: Answer the following questions: What is engineering? What does Mechanical engineering deal with? What does electrical engineering include? What is electronic engineering concerned with? What mining and medical engineering belong to? Exercise 3: Study these illustrations They show some of the areas in which engineers work Can you identify them? What kinds of engineers are concerned with these areas - electrical, mechanical, or both? a) Now read the following texts to check your answers Match each text to one of the illustrations above Transport: Cars, trains, ships, and planes are all products of mechanical engineering Mechanical engineers are also involved in support services such as roads, rail track, harbors, and bridges Food processing: Mechanical engineers design, develop, and make the machines and the processing equipment for harvesting, preparing and preserving the foods and drinks that fill the supermarkets Medical engineering: Body scanners, X-ray machines, life-support systems, and other high-tech equipment result from mechanical and electrical engineers combining with medical experts to convert ideas into life-saving and preserving products Building services: Electrical engineers provide all the services we need in our homes and places of work, including lighting, heating, ventilation, airconditioning, refrigeration, and lifts Energy and power: Electrical engineers are concerned with the production and distribution of electricity to homes, offices, industry, hospitals, colleges and schools, and the installation and maintenance of the equipment involved in these processes b) Describe if the statements are true or false Mechanical engineering includes cars, trains, ships, planes and others Mechanical engineers provide all the services such as roads, rails track, harbors and bridge Mechanical engineers design and develop body scanners, X-ray machines Electrical engineering is about the generation and distribution of electricity and its many applications Electrical engineers are involved in support all the services such as the foods and drinks that fill in the supermarket III USE OF LANGUAGE Deal with/be concerned with/be the concern of What is the link between column A and column B? A B mechanical machines electrical electricity Column A lists a branch of engineering or a type of engineer Column B lists things they are concerned with We can show the link between them in a number of ways: Mechanical engineering deals with machines Mechanical engineers deal with machines Mechanical engineering is concerned with machines Mechanical engineers are concerned with machines Machines are the concern of mechanical engineers Now match each item in column A with an appropriate item from column B and link the two in a sentence A marine aeronautical heating and ventilating electricity generating automobile civil electronic electrical installation medical a b c d e f g h i B air-conditioning roads and bridges body scanners cables and switchgear communications and equipment ships planes cars and trucks power stations Common verbs in engineering Study this list of common verbs in engineering which all has the sense of 'makes something happen' lower make low raise make high heat make hot release make free compress make smaller volume reduce make smaller increase make larger Fill in the blanks in these sentences with suitable verbs from the list above When thermoplastics are ……………., they soften If a gas is…………… it heats up Refrigeration preserves food by…………… its temperature A heater…………… the temperature of the water The rising piston…………… the fuel mixture Designers try to…………… the weight of a structure When the push button is…………… the valve spring pushes up the spool Pumping fluid into the main cylinder gradually…………… the jack Aerodynamic designs…………… wind resistance 10 The motor starts up slowly, then gradually…………… speed 11 At intermediate substations, power is …………… to 11 kV for light industry 12 When the child…………… the handle, the seat swings back under the weight IV FURTHER READING Translate the reading passage into Vietnamese then discuss the electrical engineering Electrical engineering is a field of engineering that generally deals with the study and application of electricity, electronics, and electromagnetism This field first became an identifiable occupation in the latter half of the 19th century after commercialization of the electric telegraph, the telephone, and electric power distribution and use Subsequently, broadcasting and recording media made electronics part of daily life The invention of the transistor and, subsequently, the integrated circuit brought down the cost of electronics to the point where they can be used in almost any household object Electrical engineering has now subdivided into a wide range of subfields including electronics, digital computers, engineering, telecommunications, control systems, radio-frequency engineering, signal processing, instrumentation, and microelectronics The subject of electronic engineering is often treated as its own subfield but it intersects with all the other subfields, including the power electronics of power engineering Electrical engineers typically hold a degree in electrical engineering or electronic engineering Practicing engineers may have professional certification and be members of a professional body Such bodies include the Institute of Electrical and Electronic Engineers (IEEE) and the Institution of Engineering and Technology (IET) Electrical engineers work in a very wide range of industries and the skills required are likewise variable These range from basic circuit theory to the management skills required of project manager The tools and equipment that an individual engineer may need are similarly variable, ranging from a simple voltmeter to a top end analyzer to sophisticated design and manufacturing software  ... questions: What is engineering?
