The Chinese / English bilingual edition of the history series How America Became America added authentic Chinese translation to the succinct and compelling original text in English. Also a great language learning tool to help children learn either Chinese or English by studying the American history. The 13-book series introduced how the birth and growth of the United States was shaped by centuries of thinkers and events. In the 12th book of the series, the United States of America has become the lone super power in the world. As a world leader, America also has a lot of responsibility to the rest of the world. In the twentieth century, the United States struggled to balance its power with its responsibility in new ways.
