Summary

This unit deals with the basics of electricity, it explains how electrons flow through a conductor and create an electric current. How this current is originated and powered, and how a resistor can interfere and create resistance to the flow of electrons. There is also the explanation of parallel and series circuits, with their different components. Finally, it outlines some devices which can be used to measure electricity. The aim is to make you get acquainted with specific vocabulary and expressions that you already know in your native language and which are used to discuss electrical terms.

There is a short story about two electricians, who move from one location to the other to install, revise and certify different electrical installations. This section is called “Storyline”, and it starts with the welcoming of Bill, an apprentice from UK. He is in Barcelona to assist Jordi in different works. This section is intended to show the everyday life of an electric technician, with emphasis on job related conversation. The idea is for you to get acquainted with the daily tasks that an electrician does in English.

The grammar of a language is very important because it tells you which form a word must adopt and how you must place the words in a sentence. In the first section of this unit you will study some basic words, like nouns, determiners (for example, the articles and the demonstratives) and the personal pronouns, which are used to talk about nouns (for example, I, him, her, you, etc.). Next, yo will find information about the auxiliary verbs (be, have and do), which we use to form other verb tenses. Finally, you will study other groups of basic words, like the quantifiers and the intensifiers. The quantifiers are used to express the quantity of a noun; on the other hand, the intensifiers are placed before an adjective or an adverb to add the intensity to the meaning. We will also make a special reference to the English numbers and how they are used.

This unit also deals with the four skills of a language (listening, speaking, reading and writing). In the first section, you will learn about the two oral skills (listening and speaking), and in the second section you will learn about the two written skills (reading and writing). The unit also introduces a section called ‘Everyday language’, which explains what is called the ‘functional’ or, sometimes, ‘social language’. Functional language refers to the words and expressions which we use in our daily life. In this unit, you will learn how to introduce yourself and others and how to greet people.
