The cultures of the East and the West really distinguish each other a lot. This is because the culture systems are two ______ systems on the whole.
The ______ of the eastern cultures is mainly from two countries: China and India. Both of the two cultures are gestated（孕育） by rivers. In China, the mother river is the Yellow River _____ the Indian one is the Hindu River. These two cultures were developed for several thousand years and formed their own _____. Then in Dang Dynasty of China, the Chinese culture _____ went overseas to Japan, _____ into the Japanese society and shaped the Japanese culture nowadays. Though a bit different from the Chinese one, it belongs to the same ______.

This civilization later on developed into the cultures of the Ancient Greece and Ancient Rome. And these two are well-known ______ the base of the European culture. Like the Chinese culture, the European one also ______ waters. When the colonists of England _____ in America, their culture went with them over the Atlantic Ocean.
