INTRODUCTION

      Collins Amazing People Readers are collections of short stories. Each book presents the life story of five or six people whose lives and achievements have made a difference to our world today. The stories are carefully graded to ensure that you, the reader, will both enjoy and benefit from your reading experience.

      You can choose to enjoy the book from start to finish or to dip in to your favourite story straight away. Each story is entirely independent.

      After every story a short timeline brings together the most important events in each person’s life into one short report. The timeline is a useful tool for revision purposes.

      Words which are above the required reading level are underlined the first time they appear in each story. All underlined words are defined in the glossary at the back of the book. Levels 1 and 2 take their definitions from the Collins COBUILD Essential English Dictionary and levels 3 and 4 from the Collins COBUILD Advanced English Dictionary.

      To support both teachers and learners, additional materials are available online at www.collinselt.com/readers.

       The Amazing People Club^®

It was founded in 2006 by educational psychologist and management leader Dr Charles Margerison and publishes books, eBooks, audio books, iBooks and video content which bring readers ‘face to face’ with many of the world’s most inspiring and influential characters from the fields of art, science, music, politics, medicine and business.
