THE MILL ON THE FLOSS (LEVEL UPPER INTERMEDIATE) (INCLUYE CD-ROM)

The perfect tenses ¿ both present and past ¿ are explained and used prominently in most of these readers. Many introduce the passive voice, and most feature the future tense. Nearly all of them also include exercises to develop understanding of the first conditional, and some include instruction in all three conditional forms. More modal verbs and more complex verbal constructions ¿ using gerunds and infinitives ¿ are presented. There is a generally higher level of vocabulary, sometimes quite sophisticated.
