The Macmillan Readers provide a choice of enjoyable reading material for learners of English. The series is published at six levels - Starter, Beginner, Elementary, Pre-Intermediate, Intermediate and Upper. Readers at Upper Level are intended as an aid to students which will start them on the road to reading unsimplified books in the whole range of English literature. At the same time, the content and language of the Readers at Upper Level is carefully controlled with the following main features: INFORMATION CONTROL: As at other levels in the series, information which is vital to the development of a story is carefully presented in the text and then reinforced through the Points for Understanding section. Some background references may be unfamiliar to students, but these are explained in the text and in notes in the Glossary. Care is taken with pronoun reference. STRUCTURE CONTROL: Students can expect to meet those structures covered in any basic English course. Particularly difficult structures, such as complex nominal groups and embedded clauses, are used sparingly. Clauses and phrases within sentences carefully balanced and sentence length is limited to a maximum of four clauses in nearly all cases. VOCABULARY CONTROL: At Upper Level, there is a basic vocabulary of approximately 2,200 words. At the same time, students are given the opportunity to meet new words, including some simple idiomatic and figurative English usages which are clearly explained in the Glossary.
