Grammar! For many of us, the word triggers memories of finger-wagging schoolteachers, and of wrestling with the ambiguous and complicated rules of using formal language. But what is grammar? In fact, it's the integral basis of how we speak and write. As such, a refined awareness of grammar opens a world of possibilities for both your pleasure in the English language and your skill in using it, in both speech and the written word.

Language defines us as a species, placing humans head and shoulders above even the most proficient animal communicators. But it also beguiles us with its endless mysteries, allowing us to ponder why different languages emerged, why there isn't simply a single language, how languages change over time and whether that's good or bad, and how languages die out and become extinct.

Look beyond the abstract dates and figures, kings and queens, and battles and wars that make up so many historical accounts.

Idioms in English, Volume 4 is designed for non-native speakers of English and presents 100 new idioms in stories and dialogs by native speakers. After each story or dialog, the idioms are presented in sentences with an opportunity for the listener to say the sentence (when you hear the chime) out loud. Idioms are used very frequently by native spakers of English. If you don't understand the idiom, then you can miss parts of presentations, conversations, and television or newspaper stories.

Civilization was born 8,000 years ago, between the floodplains of the Tigris and Euphrates rivers, when migrants from the surrounding mountains and deserts began to create increasingly sophisticated urban societies. In the cities that they built, half of human history took place. In Babylon, Paul Kriwaczek tells the story of Mesopotamia from the earliest settlements seven thousand years ago to the eclipse of Babylon in the sixth century BCE. Bringing the people of this land to life in vibrant detail, the author chronicles the rise and fall of power during this period.
