This book has been written to help you learn new vocabulary. You already know a large number of English words, but to express yourself more fully and in a more sophisticated way at the upper-intermediate level, you will ideally need about 4,000 words, so increasing your vocabulary is very important for your general progress in English. In this book, there are over 2,500 new words and phrases for you to learn. You will find them on the left-hand page of each unit. Every new word or phrase is used in a sentence, or in a conversation, or is in a table, or has a picture with it, or has some explanation of what it means. On the right-hand page there are exercises and other activities to help you practise using the words and to help you to remember them. The book has been written so that you can use it yourself, without a teacher. You can do the units in any order you like, but we believe it is a good idea if you do Units 1 to 4 first, as they will help you to work with the rest of the book in the best possible way.
