Long long ago there were a lot of donkeys. The donkeys worked hard every day. They had no time to play or to relax, but they never felt appreciated（得到赏识的）for the work they did.

    One day two donkeys got bored. They wanted to live a comfortable life, so the donkeys went to see a wise old man. They told him their problem. The wise old man agreed they worked too hard, and he wanted to help the donkeys. “I have an idea,” he said.

    “What is your idea?” asked the donkeys.

    “I will paint you and no one will know you are donkeys,” said the man.

    The man went off to find some paint and he returned in just a matter of minutes. He had two pots of paints. One pot was filled with white paint, and the other black paint.

    The old man first painted them white, and then painted stripes（斑纹）over the white paint. When he finished, the donkeys did not look like donkeys at all. “You no longer look like donkeys,” the old man said. “Everyone will be fooled（欺骗）. I will call you something else, zebras（斑马）.”

    The zebras went to a field to eat grass. Now they did not have to work.

    Soon, other donkeys saw the zebras. They asked the zebras where they came from. When the zebras told the donkeys their secret, the donkeys all rushed to see the old man.

    “Please make us into zebras, too,” they pleaded. So the wise old man painted more donkeys. As he did, more and more donkeys came.

    The old man could not paint fast enough. Soon the donkeys became impatient （不耐烦的）. They began to kick about, and they knocked over the paint pots.

    There was no more paint. The painted donkeys ran off to become zebras. The unpainted donkeys, because of their impatience, had to return to work.

    A punctual person is in the habit of doing a thing at the correct time and is never late for anything.

    An unpunctual man never does what he has to do at the right time. He is always in a hurry and in the end loses both time and his good name. A lost thing may be found again, but lost time can never be got back. Time is more valuable than material things. In fact, time is life itself. An unpunctual person is always wasting his most important things as well as others'. An unpunctual person is always saying unhappily that he finds no time to answer letters or return calls. But the man who really has much to do is very careful of his time. He knows that he cannot finish all his work unless he carefully does every piece of work.

    Being unpunctual is the sign of disrespect towards others. If a person is invited to dinner and arrives later than the time when he should be there, he keeps all other guests waiting for him. Usually this will be thought as a great disrespect for the host and all the other guests.

    Not like a punctual person, an unpunctual one cannot do his duty wonderfully, whether it is public or personal. Imagine how it would be if those who should do important tasks failed to be on time. A man who is known to be unpunctual is never believed by his friends or fellow men.

    Believe it or not, the size of the human brain has become smaller over the past 20,000 years. Scientists argue over whether this means we are becoming more or less intelligent as a species.

    “I'd call that a major downsizing in an evolutionary eye blink (眨眼),” John Hawks told Discover magazine.

    Why is the brain becoming smaller?

    There are different theories to explain it. One is that tens of thousands of years ago, before the decline began, to survive in cold and dangerous conditions, humans needed a stronger and larger body and therefore, a larger head. Also they had to chew the tough meat of rabbits, foxes and horses. As conditions improved, the brain stopped growing, according to supporters of this theory.

    Another theory comes from a recent study by David Geary and Drew Bailey. They found that brain size decreased as population density(密度) increased.

    “As complex societies appeared, the brain became smaller because people did not have to be as smart to stay alive.” Geary told AFP.

    But smaller brain size does not necessarily mean that modern humans are less smart than their ancestors. “Modern humans simply developed different, more complex forms of intelligence,” said Brian Hare.

    Hare's studies focus on two types of great apes: chimpanzees and bonobos. Both are much like humans, but are physically quite different from one another. The bonobo has a smaller brain than the chimpanzee, and is also much less aggressive and more tolerant.

    “When it comes to working out a problem,” Hare said, “chimpanzees are much less likely to accomplish it if it involves working together. Not so with bonobos.”

The smaller brain in modern humans may be evidence that we can cooperate,” Hare told the US National Public Radio.

Senses That Work Together

    When we think about how our senses work, we usually imagine them operating separately: you sniff a flower, and the smell is delivered uninterrupted from nose to brain. However, it's more complex than that. Most evidence for cross modal perception (知觉) comes from studies into sound and vision (视觉). But research that shows other senses crossing over is coming out all the time, and it seems that even sound and smell sometimes form an unlikely pairing.

    When New York researchers, Daniel Wesson and Donald Wilson, tried to find out the truth about a "mysterious” area of the brain called the olfactory tubercle, they had to deal with this fact. Originally, they only intended to measure how olfactory tubercle cells in mice responded to smell. But during testing, Wesson noticed that every time he put his coffee cup down, the mouse cells jumped in activity. In fact, the olfactory tubercle is well-placed to receive both smell and sound information from the outside world. Later they found that among separate cells, most responded to a smell but a significant number were also active when a sound was made. Some cells even behaved differently when smell and sound were presented together, by increasing or decreasing their activity.

    Of course, mice aren't people, so research team has been carrying out further experiments. They pulled together a group of people and gave them various drinks to smell. Participants were asked to sniff the drinks, and then match them to appropriate musical instruments and produce the notes at different levels. The results were interesting: piano was regularly paired with fruity fragrances; strong smells sounded like the instruments that are made of metal.

    Further research found that listening to different sounds can change your perceptions. Studying taste this time, the team ordered some special toffee (太妃糖) and put together “soundscapes” corresponding to bitterness and sweetness. Participants tasted similar pieces of toffee while listening to each soundscape, and found the toffee more bitter or sweeter, depending on which soundrack they were listening to.

    Studies like this are helping scientists correctly describe our understanding of the senses, and how the brain combines them with its advantage. The consequences are worth considering. Could we see musicians work together with chefs to produce sound-improved food and drink? Will you be ordering a coffee with a soundrack to bring out your favorite smell? Come to think of it, that could be one thing you hope coffee shop chains don't get round to.

    Eight years ago, Special Olympics Georgia Forsyth County was introduced to Britt Hall. Britt Hall is a Special Olympics Georgia athlete. "The first sport I started competing in with Special Olympics Georgia was softball. I was with the Forsyth Golden Gloves, and we were a pretty good team," said Britt as he looked back upon his first state game.

Since then, the athlete has competed in much more than softball. Britt has gone on to compete in bocce, basketball, athletics, table tennis, volleyball and flag football during his Special Olympics Georgia career (职业生涯). And he performed well in these games. "Athletics has always been one of his favorite sports to compete in," said Britt's father. "He likes the different competitions within athletics, especially the races (赛跑). "

    "I like athletics, but I am excited for flag football this year. We are going to play just as well as the Falcons," Britt said. This year, Britt and his teammates will be returning to Emory University as the Special Olympics Georgia Forsyth County Mean Machine, one of the two flag football teams from Special Olympics Georgia Forsyth County. Despite the word "mean" being in their name, Britt says that their aim is not to be mean to their competitors. "We want to win the gold, but we want to be nice to the other teams and encourage them. They are our friends and have worked just as hard as we have for the state competitions," Britt explained.

    While athletes are encouraged to try their very best and go for the gold, Special Olympics Georgia centers on sportsmanship and friendship during competitions. Britt has always been a good team player, but he is also very competitive. Special Olympics Georgia has helped him gain confidence as an athlete, which shows him how to cheer on his teammates and the opposing athletes.

    "I've learned a lot from being in Special Olympics Georgia. I think there is a lesson for everyone who competes," said Britt.
