The first peoples to inhabit what today is the southeastern United States sustained themselves as hunters and gathers. Sometimes early in the first millennium A.D., however, they began to cultivate corn and other crops. Gradually, as they became more skilled at gardening, they settled into permanent villages and developed a rich culture, characterized by the great earthen mounds they erected as monuments to their gods and as tombs for their distinguished dead. Most of these early mound builders were part of the Adena-Hopewell culture, which had its beginnings near the Ohio River and takes its name from sites in Ohio. The culture spread southward into the present-day states of Louisiana, Alabama, Georgia, and Florida. Its peoples became great traders, bartering jewellery, pottery, animal pelts, tools, and other goods along extensive trading networks that stretched up and down eastern North America and as far west as the Rocky Mountains.

Living with Computer
After too long on the Net, even a phone call can be a shock. My boyfriend’s Liverpudian accent suddenly becomes hard to understand after the clarity of his words on screen; a secretary’s tone seems more rejecting than I’d imagined it would be. Time itself becomes fluid – hours become minutes, and alternately seconds stretch into days. Weekends, once a highlight of my week, are now just two ordinary days.
For the last three years, since I stopped working as a producer for Charlie Rose, I have done much of my work as a tele-commuter (远程交谈者). I submit articles and edit them via E-mail and communicate with colleagues on Internet mailing lists. My boyfriends lives in England, so much of our relationship is computer-mediated.
If I desired, I could stay inside for weeks without wanting anything. I can order food, and manage my money, love and work. In fact, at times I have spent as long as three weeks alone at home
