For millennia man has exploited and often destroyed the richest of land. Now man focuses on the wealth of the oceans. Even the most conservative estimates of resources in the seabed astonish the imagination. In the millions of miles of ocean that touch a hundred nations live four out of five living things on earth. In the seabed, minerals and oil existed in lavish supply. Man may yet learn to use a tiny fraction of this wealth. However, this fraction alone could set off a new age of colonial war unless international law soon determines how it shall be shared.

What is to be done to manage and control exploitation of the ocean is a problem of international concern. In crowded England, serious plans have developed to build entire cities just off the coast. Offshore airport may solve the demand for large tracts of jet – age space near such large coastal cities as New York and Los Angeles. Some people, quick to take advantage of the legal confusion that reigns beyond coastal waters, have planned to build independent islands above seamounts and reefs outside the country’s territorial limit – that is indeed, a romantic idea, but one with, it is suspected, the more prosaic aim of avoiding the constrictions of domestic law concerning gambling and taxes. In another case the United Nations were presented with an application for permission to extract mineral from the bed of Red Sea in an area 50 miles from the coastal states. The Secretariat avoid this hard question, citing lack of authority to act. Such claims are no longer isolated.

The great wealth from the oceans must be divided among nations. But wealth is not the only thing at debate. We must also learn how to protect the oceans from the threat of pollution. A few years ago, “practical” men dismissed speculations about wealth in the sea. “That is economic foolishness,” they said. It will never be economical profitable to exploit the seabed’s, no matter how great the riches to be found there are. Unfortunately, in these pioneer years of the Ocean Age, the damage done sometimes seems to exceed the benefit gained. Largely in ignorance, we are tinkering with our greatest source of life.

We should get seven or eight hours a night but a lot of us get by just five or less, and some of us actually sleep too much. A study out of the University of Buffalo last month reported that people who routinely sleep more than eight hours a day and are still tired are nearly three times as likely to die of stroke--probably as a result of an underlying disorder that keeps them from snoozing(light sleep) soundly.

　Doctors have their own special sleep problems. Residents are famously sleep deprived. When I was training to become a neurosurgeon, it was not unusual to work 40 hours in a row without rest. Most of us took it in stride, confident we could still deliver the highest quality of medical care. Maybe we shouldn't have been so sure of ourselves. An article in the Journal of the American Medical Association points out that in the morning after 24 hours of sleeplessness, a person's motor performance is comparable to that of someone who is legally intoxicated. Curiously, surgeons who believe that operating under the influence is grounds for dismissal often don't think twice about operating without enough sleep.

　"I could tell you horror stories," says Jaya Agrawal, president of the American Medical Student Association, which runs a website where residents can post anonymous anecdotes. Some are terrifying. "I was operating after being up for over 36 hours," one writes. "I literally fell asleep standing up and nearly face planted into the wound."

　"Practically every surgical resident I know has fallen asleep at the wheel driving home from work," writes another. "I know of three who have hit parked cars. Another hit a 'Jersey barrier' on the New Jersey Turnpike, going 65 m.p.h."

　The U.S. controls the hours of pilots and truck drivers. But until such a system is in place for doctors, patients are on their own. If you're worried about the people treating you or a loved one, you should feel free to ask how many hours of sleep they have had and if more-rested staffers are available. Doctors, for their part, have to give up their pose of infallibility and get the rest they need.

What is eBay? The simple answer is that it is a global trading platform World Records where nearly anyone can trade practically anything. People can sell and buy all kinds of products and goods. Including cars, movies and DVDs, sporting goods, travel tickets, musical instruments, clothes and shoes---the list goes on and on.

The idea came from Peter Omidyar, who was born in Paris and moved to Washington when he was still a child, at high school, he became very interested in computer programming and after graduating from Tuft University in 1988, He worked for the next few years as a computer engineer. In his free time he started Bay as a kind of hobby, at first offering the service free by word of mouth. By 1996 there was so much traffic on the website that he had to upgrade(升级) and he began charging a fee to members. Joined by a friend, Peter Skill, and in 1998 by his capable CEO, Meg Whitman, crashes of the late 1990s, eBay has gone from strength to strength. It is now one of the ten most visited online shopping websites on the Internet.

eBay sells connections, not goods, putting buyer and seller into contact with each other. All you have to do is to take an e-photo, write a description, fill out a sales form and you are in business; the world is your market place. Of course for each item(商品) sold eBay gets a percentage and that is a great deal of money. Every day there are more than sixteen million items listed on eBay and eighty percent of the items are sold.
