INTRODUCTION

Today it is very clear the importance of englishas a means of world communication in the industry,commertre, scienceand technology.Englishis the essentialtool to make possiblethe technicalknowledgeof students who need to be related with topics of thern fuLurecar€ers as technicianson engineens. The main purpose of this textbook is to providethe studenLsthe basic gnammatical and lexicalstructures of technicalenglishin ondento improvethein comprehensionand, if possible,to make them communicatetheir own ideas in technicalmatbers. Since the attention ls dinected mainly to the language, not to technical details of matenials,tools on machines,the text can be used with confidenceby gener-alenglish technicalknowledge. teachenswho have liuule grammar have been canefullyselected and gnaded. They ane and The vocabulary on woodwork, metalwork,technical drawing, mechanics litenature technical common to on elecbricity. The texUis dividedinto five units, each one based on technicalmaterial of all tnades. Ahhough it is assumedthat students using this book have alreadyreceiveda certain tr.ainingin the english language at the basic school, there is a fir-st unit intended to check some genenalgramman requinementsneededat this level. The linguisücmatenialis presentedthrough common siLuationsin dialogues,picbures and r-eadingtexbs.Then, it can be pnactisedand reinforcedin vocabularyand gramman exercises,which may be onalon wnitten. Charts containingthe main grarnman points in the unit, and some games to make the classworkmore attnactive,are found at the end of each unit. The complementanyneadingsane a helpfulnesourcefor the teachen, used as motivation, and they can give the most advanced students the possibilityto improve thein compr€hensionin englishand the abilityto tnanslateenglishtechnicaltexts. All the technical vocabularyand venbs introduced in this finst book are listed at the end of it. TechnicalEnglish7 is the result of many years of experiencein teachingthe language at secondarytechnicalschools. We expect the contents will help the students to become familiar with technical english at, a basic level and at the same time be a valuablecontributionfon the improvementof classroom activitiesin the teachingand leanningpnocess.
