Материалы последнего цикла нацеливают на общение и носят выраженную коммуникативную направленность. 6 UNIT I 7 Text 1 Engineering Thinking Engineering is putting knowledge of Nature to practical use. <...> The final product of engineering is some physical thing: a machine, a tool, a garget. <...> A good engineer first …, second …, next …, then …, and last … a) defines the problem; b) verifies the solution; c) identifies possible solutions; d) implements the solution; e) selects a solution.. <...> Wordlist engineering – инженерное дело, техника final product – конечный продукт tool – инструмент to solve a problem – решить проблему framework – основа creative mind – творческий ум obligatory – обязательные desirable – желательный, заданный feedback – обратная связь Answer the questions. 1. <...> The wheel, one of the greatest inventions ever made by man is also of prehistoric origin. <...> It is mentioned by the Greek Philosopher Aristotle as a means of lifting a great weight by using a very small force. <...> Tremendous changes in machine development were made in the 20 th century. <...> Wordlist activity – деятельность multitude – множество, огромное количество bow and arrow – лук и стрела to be of recent origin – быть недавнего происхождения implement – орудие, приспособление wheel – колесо inclined plane – наклонная плоскость slave – раб lever – рычаг powerful device – мощное устройство Answer the questions. 1. <...> What can you say about machine development in the 20th century? <...> Text 3 The internal combustion engine The internal combustion engine is an engine in which the combustion of a fuel (normally a fossil fuel) occurs with an oxidizer (usually air) in a combustion chamber that is an integral part of the working fluid flow circuit. <...> In an internal combustion engine (ICE) the expansion of the high-temperature and high-pressure gases produced by combustion apply direct force to some component of the engine. <...> The first commercially successful internal combustion engine was created by Étienne Lenoir The cycle is characterized by four strokes, or straight movements alternately, back and forth, of a piston inside a cylinder: 1. 2. 3. 4. intake (induction) stroke compression stroke power (combustion) stroke exhaust stroke <...>
