Although morning types may achieve more academically, night owls tend to perform better on measures of memory, processing speed and cognitive ability, even when they have to perform those tasks in the morning. Night-time people are also more open and more creative. And one study shows that night owls are as healthy and wise as morning types—and a little bit wealthier.
Still think the morning people sound more like CEO material? Don't set your alarm for 5 am just yet. As it turns out, overhauling(大修) your sleep times may not have much effect.
“If people are left to their naturally preferred times, they feel much better. They say that they are much more productive. The mental capacity they have is much broader，” says Oxford University biologist Katharina Wulff. On the other hand, she says, pushing people too far out of their natural preference can be harmful. When they wake early, for example, night owls are still producing melatonin(褪黑激素). “Then you disrupt it and push the body to be in the daytime mode. That can have lots of negative physiological consequences，” Wulff says, like a different sensitivity to insulin and glucose(葡萄糖)—which can cause weight gain.

GPS technology is one of the latest and greatest developments within the communications world. Also known as a “global positioning system，” this technology works off of radio signals sent out by satellites in space. Since a cell phone already works like a two-way radio when communicating with cell towers, the GPS capability simply extends the radio signal reach to space satellites. Phones equipped with full-featured capabilities work off of Java-based radio signals and
have database access to their providers' system for other data like mapping and voices. Location tracking, and giving directions to and from destinations are some of the more common uses for this technology.
GPS navigational systems are supported by a network of 27 satellites. These satellites orbit the Earth in cyclic patterns 24 hours a day. At any given time, a minimum of four satellites signals is accessible to any one point on Earth. Whenever a receiver device is activated, radio waves with coded messages are sent out to it. This is how satellites know to start tracking the device. A
receiver's exact location is determined through a process called trilateration(三边测量法) where three satellites work together to narrow down possible location points. A fourth satellite is needed if the receiver isn't on the ground and altitude is wanted as well. Distance calculations are made based on how long it takes the radio signals to travel back and forth between receiver and satellites. The mapping capabilities are displayed on the phone's screen via the cell provider's database.
As a GPS device needs to do all kinds of calculations on different data from satellites and provider'S database，it consumes time. So it can take quite a few seconds for a regular GPS to work out a plan. An assisted GPS can help solve the problem. It is an improved technology that uses a cell network's Assistance Server which is connected to a reference network such as the Internet. Through the use of cell towers，a phone relays satellite signal information to the servers. These servers are able to process incoming data at much higher rates than GPS receivers，so information is processed quicker，and is typically more accurate.

Myth was born in childhood of human being. It is a product of ancient imaginations, which can conquer nature，dominate nature and make the power of nature have its own image. It is a cultural phenomenon in civilized society.
China and Greece are birthplaces of Orient and Western civilizations. Prime Minister Constantine Caramanlis of Greece once pointed out: “The civilization of China brought light to the Far East and the whole of Asia，as Greece thought，the cornerstone of European civilization，brought light to the West.” However，for some reasons，there are many differences between Chinese and Greek myth，which show their own unique national spirits and moral principles.
The ancestors of Chinese nation lived on land before one million and seven hundred thousand years. After long uncivilized times, ancient Chinese gradually created civilization. In prehistory, ancient Chinese lived and struggled. Most ancestors' achievements of tribes have been passed down orally. This is old myth. According to some archaeological materials, single myth, which has the meaning of totem(图腾), had appeared in the Late Palaeolithic Age. As the mental belief, totem is the holiest and the most beautiful symbol in ancient tribes' mind. It is their aesthetic conception(审美观). On the contrary, the history of Greece is shorter, and Greek myth produced later than Chinese myth. It produced in about eleventh century BC, and it was far from the age of totem worship. That was the Age of Heroes. Human wisdom had been more and more important and totem worship had tended to disappear. So ancient Greeks thought that human being was the most beautiful in the world. They gave their deities(神灵) the most beautiful images. Those are images
