Book 5 focuses on air travel, meals and medical matters. It builds upon the student's knowledge of first form verbs by introducing various defective forms (verbs containing one or more weak root letters). The book also extends the student's understanding of cardinal numbers into the thousands and suggests practical applications for their use. Passages of dialogue, sample emails, and model telephone conversations enable the student to gain greater confidence and fluency in using Arabic, while comprehension passages challenge the learner to extend their understanding. This book covers: ? Air travel ? Food ? Ordering a meal in a restaurant ? Hospital and doctors' appointments ? Medical problems ? Cardinal numbers from 1 to 1000 and beyond ? Practical application of numbers ? Telephone numbers and email ? Over 150 past and present tense verbs ? Reference list of nouns and their plurals.
