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. At Intermediate Level, the control of content and language has the following main features: INFORMATION CONTROL: Information which is vital to the understanding of the story is presented in an easily assimilated manner and is repeated when necessary. Difficult allusion and metaphor are avoided and cultural backgrounds are made explicit. STRUCTURE CONTROL: Most of the structures used in the Readers will be familiar to students who have completed an elementary course of English. Other grammatical features may occur, but their use is made clear through context and reinforcement. This ensures that the reading as well as being enjoyable, provides a continual learning situation for the students. Sentences are limited in most cases to a maximum of three clauses and within sentences there is a balanced use of adverbial and adjectival phrases. Great care is taken with pronoun reference. VOCABULARY CONTROL: There is a basic vocabulary of approximately 1,600 words. Help is given to the students in the form of illustrations, which are very closely related to the text.
