Article: For a commuter rushing to catch a train, a minute can mean the difference between dinner with the family and leftovers   in the microwave. What most passengers don't realize is that their minute is already there. Every commuter train that departs from New York City -- about 900 a day -- leaves a minute later than scheduled. If the timetable says 8:14, the train will actually leave at 8:15. In other words, if you think you have only a minute to get that train -- well, relax. You have two. The courtesy   minute, in place for decades and published only in private timetables for employees, is meant as a grace period for those who need the extra time to get off the platform and onto the train. "If everyone knows they get an extra minute, they're going to waste time doing unimportant things," explained Marjorie Anders, a spokeswoman for the Metro-North Railroad. Told of this article, Ms. Anders laughed. " _ !" she said. Entirely hidden from the riding public, the secret minute is an odd departure from the railroad culture of down-to-the-second accuracy. The railroad industry helped invent the concept of standard time, and time zones were established in the United States in the 1880s, 35 years before they were written into law. And most commuters know their train by the precise minute it departs. The trains quickly make up the minute: at all other stops, the public timetable prevails. The phantom minute does not exist at commuter railroads in Chicago, Los Angeles, Philadelphia, or San Francisco. But in New York, the secret minute dates back decades. "That's been done forever, from my knowledge," said Jack Swanberg, 70, an unofficial historian of Metro-North. "I was the trainmaster starting in 1970 and I'm sure it's been the case since 1870 for all I know."

Article: After many years on the endangered list of animals, Japan'sAmami Black rabbit can finally breathe a sigh of relief -- That's because this year, the rare animal is no longer in danger of dying out! The effort to save the dark-furred rabbit, often called "a living fossil", began in 1921, when the Japanese government promoted it to the status of "natural monument". This meant that it could not be hunted down for food. However, when that did not work, it got yet another promotion to "special natural monument", which meant that the rabbit could not be trapped or hunted. While that helped, it was not enough -- By 2004 with only 2,000-5,000 specimen   left in the wild, the Amami rabbit was officially declared endangered! The reason for the serious population decrease was due to loss of habitat caused by forest clearing for home and agriculture use and the introduction of a new species not native to the island -- the Mongoose. Brought in to get rid of the snake population, the Mongoose instead seemed to prefer the black rabbit. In 2005, the government carried out a strict mongoose capture   order and slowly but surely, the rabbit started to come back. This rabbit live in a rather unusual lifestyle. Its ideal habitat is a forest that features both trees and large grasses -- the former to find acorns   to feed on and the latter, to hide its babies. That's because to protect them from being eaten by their enemies, the Amami rabbit buries them deep into the ground among the grasses and covers them up with dirt during the day. Then, in the middle of the night, still keeping a _ eye out for their enemies, it digs them out from their hiding place and feeds them. No wonder the animal is sometimes called "midnight rabbit". Though many measures have been taken to stop this furry animal from being wiped out from the world, there are many more that are still in danger. We surely hope that officials in other parts of the worldtry their best to save the endangered species.

Article: One of the greatest warriors  of history, Genghis Kahn, came from the Mongolian people. He controlled many countries in Asia and Europe because of his bravery and leadership in battle. This time period was known as the Yuan Dynasty in the 13th and 14th centuries. Genghis decided to go hunting one day and many of his warriors went with him. Genghis had his favorite hawk on his wrist. The hawk was trained to fly high in the air to look for game like deer, rabbits or wild birds. When his bird flew to the ground, Genghis would follow it and shoot the wild game with his arrows. It was his favorite hobby. This particular day, game was hard to find. Toward evening, Genghis sent all the men home and decided to go another way by himself. He even let his hawk go, thinking it would fly home as well. He became thirsty so he stopped by some rocks where he noticed water was dripping. He took a cup from his pack and filled it slowly. When he put it to his mouth, he was surprised for his hawk came and spilled   all the water in his cup. He thought this was very unusual so he filled the cup again. The hawk rushed down and knocked the cup free from his hand. Genghis was now thirsty and angry. As he filled the cup a fourth time, he drew his sword to stop the bird interrupting him. As the bird flew down, Genghis killed it but his cup fell deep into the rocks in the scuffle  . He decided to crawl up the rock of the mountain to find the source of the water. He found a pool and noticed a huge poisonous snake was dead in the water. He realized the hawk had saved his life. His anger had caused him to kill his favorite bird. In his despair  , he promised to make sure of everything before he would become angry again.
