Accion Gramatica!: New Spanish Grammar by Phil Turk
This grammar reference and practice book deals with nouns, articles and adjectives at one end of the scale, and the subjunctive, compound tenses and the passive at the other. Each of the chapters deals with a specific grammatical point. Explanations are given in English, and examples and exercises are in Spanish. Each chapter has three sections: "Mecanismos" (tools), giving explanations of grammatical points; "Ponte a punto" (get ready/tune up/limber up), giving controlled practice exercises; and "...Y en marcha" (off you go), providing open-ended practice for more creative use of language. Other features include - a section on Spanish spelling, keys containing answers to "Ponte a punto" sections and a verb reference table. Phil Turk and Mike Zollo are co-authors of "Ahora Mismo", "Palabra por Palabra", "Arreglatelas" and "Manejate".
