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 quantifers 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. Before this grammar section, you will see the storyline, where you can see some examples of the grammar points in context.

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.
