One day, Mr. Smith went to a dinner party. He was wearing very old clothes. He came into the room.But people in the room didn't look at him. They didn't ask him to sit at the table. He wasn't happy. But he said nothing.Mr. Smith went home quickly and put on his best clothes. He went back to the party. Everyone in the room stood up and looked at him. They gave him good food to eat.Mr. Smith took off his coat, and put it on the food and said, "Eat, coat!" The other people were surprised and asked, "What are you doing? Why do you do that?" Mr. Smith answered, "I am asking my coat to eat food. When I wore old clothes, you didn't look at me. You didn't ask me to sit down. Now I am wearing these nice clothes. And you give me good food. Now I see, you give the food to my coat, not to me."

    The Mokoko tribe (部落) lived on the wrong side of the island of two faces. The two sides, separated by a great cliff (悬崖), were like night and day. The good side was watered by rivers and was filled with trees and abundant food, while on the wrong side there was hardly any water or plants, and wild beasts crowded together. The Mokoko had the misfortune of having always lived there, with no way to cross to the other side. Their life was hard and they lived in permanent terror of the beasts.

    Along the edge of the cliff separating the two sides, a skinny but strong tree grew, with which they could build two poles. There was no doubt that the tribe would choose the great chief and doctor to use the poles. But when the two of them were given their chance to make the jump, they didn't dare to. They thought that the pole could break or it would not be long enough. They put so much energy into these thoughts that they gave in.

    But into that tribe were born Nam and Ariki, a pair of young hearts. One day, they decided to take up the poles. Nobody stopped them, but everyone did try to discourage them, trying to present how dangerous the jumping was, using a thousand explanations.

    "And what if what they say is true?" wondered the young Naru.

    "Don't worry. I am a bit scared too, but it doesn't look so difficult," replied Ariki, ever determined.

    "But if it goes wrong, it will be a terrible end," continued Naru, undecided.

    "Perhaps the jump will go badly. But staying forever on this side of the island surely won't work out well either."

    "You're right. Let's do it tomorrow."

    And on the next day, Naru and Ariki jumped to the good side of the island. When taking up the poles, while feeling their desire, the fear hardly allowed them to breathe. And while flying through the air, helpless and without support, they felt that something must have gone wrong and death awaited them. But when they landed on the other side, they thought the jump really hadn't been so bad after all.

    About 5,000 children die each day due to preventable diseases such as cholera and dysentery (痢疾) , which spread when people use unclean water for drinking or cooking. A lack of water for personal health leads to the spread of totally preventable diseases like trachoma, which has blinded some six million people.

    Water troubles also trap many low-income families in a cycle of poverty and poor education and the poorest suffer most from lack of access to water. People who spend much of their time on ill health, caring for sick children, or collecting water at distances averaging 3.75 miles a day don't have educational and economic opportunities to better their lives.

    Agriculture is called the lion's share of freshwater worldwide, using some 70 percent, and industrial uses consume another 22 percent. Water areas have no political borders and nations don't always work together to share common resources, so water can be a frequent source of international conflict as well.

    Day-by-day demand keeps growing, further needing water sources, from great rivers to groundwater. “We're going deeper into debt on our groundwater use,” Postel said, “and that has very significant impacts on global water security. The rate of groundwater consumption has doubled since 1960.”

    Some of Earth's groundwater is fossil water created when Earth's climate was far different. Today such water is as limited as petrol. “But we're pumping much of them out faster than ever,” Postel explained. “Humanity's growing thirst also causes a major problem about water and our ecosystems. And that also creates a cost to us, to our sons and to our grandsons, not just to nature.”

    A pretty face is never forgotten. Do you believe so? But maybe it is untrue! Psychologists believe beautiful people are less likely to be recognized. A new study suggests that attractiveness can actually prevent the recognition of faces, unless a pretty face has particularly distinctive features, such as Angelina Jolie's.

    German psychologists think the recognition of pretty faces is distorted (扭曲) by emotions. Researchers Holger Wiese, Carolin Altmann and Stefan Schweinberger at the University of Jena, Germany, discovered in a study that photos of unattractive people were more easily remembered than pretty ones when they showed them to a group of people.

    For the study, which was published in science magazine Neuropsychologia, the psychologists showed photos of faces to test subjects. Half of the faces were considered to be more attractive and the other half as less attractive, but all of them were being thought of as similarly distinctive looking. The test subjects were shown the faces for just a few seconds to memorize them and were shown them again during the test so that they could decide if they recognized them or not.

    The researchers were surprised by the result. “Until now we assumed that it was generally easier to memorize faces which are being considered as attractive, just because we prefer looking at beautiful faces,” Dr. Wiese said. But the study showed that such a connection cannot be easily proven. He assumes that remembering pretty faces is distorted by emotional influences, which enhance the sense of recognition at a later time. The researchers' idea is backed up by evidence from EEG-recordings (脑电图记录) they used during their experiment which show the brains' electric activity.

    The study also revealed that in the case of attractive faces, considerably more false positive results were detected. In other words, people thought they recognized a face without having seen it before. “We obviously tend to believe that we recognize a face just because we find it attractive.” Dr. Wiese said.

ZOOKEEPER FOR A DAY

    Go wild with an extreme zookeeping experience!

    The Khaki Extreme program is a wild behind-the-scenes zookeeping adventure like no other! The program offers the chance for 11-15 year olds to see first-hand what's involved in looking after amazing wildlife at Australia Zoo.

    During the guided adventures, you'll gain an understanding and appreciation of what's involved in working in one of the world's most popular zoological and conservation areas, and you'll love getting up close with the awesome animals.

    Whether it's helping keepers prepare diets for the animals, cleaning enclosures (围场) for large animals, or making improved activities for Australia Zoo's wildlife — you will have a chance to get involved at grass-roots level.

    After a busy morning getting up close with wildlife, you can enjoy a specially provided lunch while watching the performance in the world-famous Crocoseum. Then you'll also receive a guided behind-the-scenes tour of the Australia Zoo Wildlife Hospital. Here you'll see the kind veterinary (兽医的) team treating sick and injured native wildlife, and you'll learn what you can do to protect Australia's native wild animals.

    Every season is different and so is our Zookeeper for a Day Khaki Extreme program! We'll change the animals and activities each school holiday period to keep it exciting, but with so many great animals on offer, the Khaki Extreme program is always a bunch of fun.

    If reptiles (爬行动物) are more your thing, check our Zookeeper for a Day Khaki Extreme Reptile program. Here you'll have a wild day out with some of Australia Zoo's most scaly (有鳞屑的) and slippery friends. This program may not be available every school holiday period and program dates will be limited. Check the booking page for further details on availability.
