Fluent English: Perfect Natural Speech, Sharpen Your Grammar, Master Idiomatic Expressions, Speak Fluently by Barbara Raifsnider

ESL (English as a Second Language) students who reach an intermediate level of English don’t need endless drills in grammar or tedious vocabulary lists; they need to learn how to make their English sound natural. Fluent English is the ideal course for developing native-like fluency in English. It focuses on the essentials—idiomatic expressions, phrasal verbs, practical vocabulary expansion, and grammar usage in context—and builds listening comprehension as well as pronunciation and intonation skills.
