• Sommario/riassunto: Spanish is the official language of Spain and 21 Latin American countries, and is an official language of the U.N. Pimsleur's Spanish teaches an educated Latin American Spanish, with speakers from Colombia and Argentina in levels I-III, and from Mexico in level IV.The Pimsleur® Method: the easiest, fastest way to learn a new language. Completely portable, easily downloadable, and lots of fun.Youll be speaking and understanding in no time flat! Spanish Phase 1, Lessons 1-30 includes 15 hours of spoken language practice and one hour of reading instruction in thirty, 30-minute lessons.In the first 10 lessons, youll cover the basics: saying hello, asking for or giving information, scheduling a meal or a meeting, asking for or giving basic directions, and much more. Youll be able to handle minimum courtesy requirements, understand much of what you hear, and be understood at a beginning level, but with nearnative pronunciation skills.In the next 10 lessons, youll build on what youve learned. Expand your menu, increase your scheduling abilities from general to specific, start to deal with currency and exchanging money, refine your conversations and add over a hundred new vocabulary items. Youll understand more of what you hear, and be able to participate with speech that is smoother and more confident.In the final 10 lessons of Phase 1, youll be speaking and understanding at an intermediate level. In this phase, more directions are given in the target language, which moves your learning to a whole new plane. Lessons include shopping, visiting ; friends, going to a restaurant, plans for the evening, car trips, and talking about family. Youll be able to speak comfortably about things that happened in the past and make plans for the future.Reading Lessons are included at the end of Unit 30 to provide you with an introduction to reading Spanish. These lessons, which total about one hour, are designed to teach you to sound out words with correct pronunciation and accent. A Reading Booklet to be used with the audio lessons is also included in PDF format.
