This manual is an add-on book to the course book "English for Business Studies" (Ian MacKenzie, 3rd edition). It targets students that learn ESP. The manual is divided into 28 units. Each unit in its turn is divided into four parts. The first two parts are aimed at consolidating and expanding students' knowledge, the third and fourth parts reflect the communicative approach to learning Business English and they are aimed at practicing the skills students have acquired in typical situations of business communication.
