Argomento e obiettivi del testo
 It Works! è un corso di inglese tecnico per gli studenti dei corsi con indirizzo Elettronica, Elettrotecnica e Meccanica, con focus sulla Manutenzione e Assistenza Tecnica.
 
 I contenuti, veicolati attraverso testi di livelli di diversa complessità, vengono esplorati utilizzando le quattro abilità in modo omogeneo ed integrato. Il testo dà inoltre grande importanza alla pratica linguistica attraverso attività che agevolano la revisione e la ripetizione dei contenuti studiati, favorendone l'apprendimento e l'interiorizzazione.
 I brani offrono un assortimento di stili, registri e livelli di difficoltà, e sono tratti da fonti diverse ed autentiche: libri e manuali, riviste e quotidiani online e siti web, anche specialistici.
 
 Il testo si propone di:
 
 <ul><li>far acquisire le competenze necessarie per comprendere testi che presentano termini, espressioni, strutture sintattiche e modalità discorsive specifiche del linguaggio settoriale;
</li><li>migliorare le capacità di ricezione e produzione orale e scritta;
</li><li>consolidare abitudini grammaticali corrette;
</li><li>incoraggiare l'autonomia linguistica e la soluzione di problemi;
</li><li>stimolare l'interesse e la partecipazione attiva degli studenti, dando spazio alla loro esperienza personale e a problematiche di attualità.
</li></ul>La struttura
 It Works! è diviso in cinque Moduli, ognuno dei quali ripartito in un numero variabile di Unità.
 Ogni Unità è suddivisa in brevi Capitoli su due pagine – teoria ed esercizi – per favorire sia uno studio più parcellizzato, sia la scelta antologica da parte dell'insegnante.
 
 Brevi link (curiosità, ampliamenti, rimandi, attività o mini-approfondimenti) arricchiscono i brani per consentire una maggiore interattività. Il primo esercizio di ogni capitolo è sempre una mappa riepilogativa da completare che aiuta a focalizzarsi sulle key words e i contenuti chiavi del testo proposto.
 Un ricco apparato iconografico, infine, accompagna i brani di lettura, per ognuno dei quali è previsto un esauriente glossario.
 
 Ogni Unità si conclude con tre sezioni:
 
 <ul><li>Vocabulary and Praseology: attività di revisione e consolidamento del lessico;
</li><li>Case study: argomento di attualità corredato di esercizi mirati all'approfondimento e alla discussione;
</li><li>Mapping your Mind: mappa riepilogativa per rappresentare la rete di relazioni tra i vari argomenti delle unità e a fissare le key words.
</li></ul>Alla fine di ogni Modulo, il testo propone ulteriori attività:
 
 <ul><li>Real-Life skills: compiti di realtà reali e collaborativi, con un taglio di tipo pratico calato nella realtà;
</li><li>Clip: brevi filmati tratti da opere cinematografiche.
</li></ul>Contenuti digitali integrativi
 
 <ul><li>Video per attività di listening e speaking
</li><li>Tracce audio in formato mp3
</li><li>Schemi e mappe interattive
</li><li>Testi per attività di approfondimento e di esercitazione
</li><li>Schede di civiltà comparata UK vs US
</li></ul>Teacher's Book. Disponibile sia in formato cartaceo sia digitale.
 
 <ul><li>Programmazione didattica / Piano di lavoro
</li><li>Didattica inclusiva e BES
</li><li>Agenda 2030
</li><li>Test di verifica di tutte le Unità e i Moduli, in formato editabile

40 The phase of a motor is the number of separate electric currents giving power to the coils independently. CNC machine: macchina a controllo numerico crane: gru lathe: tornio stepper motor: motore passo passo suitable: adatto turntable: piatto/ piattaforma girevole to weld: saldare TYPES OF ELECTRIC MOTORS   AC motors AC motors can be divided into two main categories.   Asynchronous motors. The name of these types of motor is due to the fact that their rotor turns at a speed which is lower than that of the rotating magnetic field. These types of motor can be further divided into singlephase and three-phase motors.   Single-phase motors are powered by single-phase AC current ; they are suitable for driving small machines such as appliances in homes and small businesses;   Three-phase motors are selfstarting motors and are extensively employed in industry as they are smaller, lighter, more efficient, and require less maintenance than other types of motors. They are mainly employed to drive lathe machines, oil extracting plants, and for a lot of different industrial machines.   Synchronous motors. Here, the rotor is designed to rotate at the speed of the revolving magnetic field of the stator. These motors are generally used in devices requiring a constant and precise speed. Typical applications of synchronous motors are watches, record players, and turntables.   Types of DC motors DC motors fall into two main categories: brushed and brushless motors.   In brushed motors, carbon brushes are in contact with the commutator in the rotor to transfer the electric voltage to it. The design of this type of motor is simple and relatively cheap; however, it is less efficient and requires more maintenance than a brushless motor as brushes wear out after some time and can create sparks while the motor works. Because they are low-cost and easy to operate, brushed motors are traditionally employed in industry to drive cranes and other types of heavy machinery.   In brushless motors, an electronic controller, instead of brushes, reverses the direction of the current to cause the rotation of the magnetic field. A brushless motor is more expensive and has a more complex design; on the other hand, it offers a more precise speed control, lasts longer, and needs less maintenance than brushed motors. The stepper motor is one of the most commonly used brushless motors. It can divide a full rotation into an equal number of steps and its work can be accurately controlled. Stepper motors are used in 3D printing equipment, CNC machines, and welding equipment.
