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
</li><li>Soluzioni degli esercizi e note didattiche
</li><li>Audioscript delle attività di ascolto e dei video</li></ul>

These machines are essential in manufacturing to achieve high precision,   the tailstock, which is at the right end of efficiency, and repeatability in producing the machine and applies support to the parts and components. workpiece along the longitudinal axis.   The lathe A lathe is a machine tool used to shape materials such as metal, wood, or plastic. It operates by utilising workpiece rotation, in other words by rotating the workpiece around a horizontal axis while it is securely clamped. Various cutting, drilling, sanding, threading, or shaping tools are mounted on a tool post, which can be adjusted to move against the rotating workpiece. This setup enables the execution of various operations, making the lathe an essential tool for shaping materials with high precision and efficiency. ONLINE RESOURCES TYPES OF LATHE OPERATIONS   Parts of a lathe A lathe is made up of the following main parts:   the bed, which is the base on which the lathe is placed;   the carriage of the machine, which slides on the bed;   the lead screw, for cutting threads, i.e. helical grooves, in or on a cylindrical workpiece;   the carriage handwheel, which manually moves the carriage;   the headstock, which is located at the left end of the bed and transmits power to the different parts of the lathe;   the spindle, which holds the workpiece while rotating;   Types of lathes Different types of lathes can be used for different machining operations. The main ones are the following.   A speed lathe machine is a highspeed , hand-operated lathe machine, mainly used by woodworkers.   An engine lathe machine is the most popular type of lathe which can be found in almost any workshop. It can operate on very big workpieces , it is used both for woodworking and metalworking and can perform various operations such as turning, facing, grooving, knurling, drilling, and boring.   A turret lathe machine is an advanced lathe machine used for mass production. It is an upgraded version of the engine lathe, where the tailstock is replaced by a revolving hexagonal turret.   A bench lathe machine is a smallsize, hand-operated power lathe mainly used for small precision works, for example in jewellery.   A CNC lathe machine is the most up-to-date lathe in terms of technology. It works with a computer numeric control system (CNC) that can start and perform the machining operations according to CAD/CAM program input.
