"Everybody is a genius.But if you judge a fish by its ability to climb a tree,it will live its whole life believing that it is stupid."—Albert Einstein

    If you have a kid with special needs in the school system,chances are you have come across that saying hanging on a classroom wall.My five-year-old daughter Syona has cerebral palsy（脑瘫）and it means,combined with her communication and sight problems,that normal standard isn't always an accurate measure of her abilities.

    By now you have probably heard about Chris Ulmer,the 26-yearold teacher in Jacksonville,Florida,who starts his special education class by calling up each student individually to give them much admiration and a high-five.I couldn't help but be reminded of Syona's teacher and how she supports each kid in a very similar way.Ulmer recently shared a video of his teaching experience."I have seen their confidence increase rapidly."he said.All I could think was: how lucky these students are to have such good teachers.

    Syona's teacher has an attitude that can best be summarized in one word: awesome.Her teacher doesn't focus on what can't be done—she focuses on what can be done.Over the past several months,my husband Dilip and I have seen Syona's confidence increase tenfold.She uses words she wouldn't have thought of using before.She recently told me about her classmate's trip to Ecuador and was very proud when I understood her on the first try.

    I actually wonder what the influence would be if we did something similar to what Ulmer does with his students in our home.We've recently started our day by reminding each other of the good qualities we all possess.If we are reminded of our strengths on a regular basis,we will become increasingly confident about progress and success.

    Dogs were living as companions to the early settlers of North America over 10,000 years ago. The oldest domestic dogs in the Americas were thought to be around 9500 years old. Angela Perri of Durham University, UK, and her colleagues have carried out fresh radiocarbon dating on the two dog skeletons that gave this date, discovered in the prehistoric Koster site in Illinois, and found they were even older: around 10,100 years old.

    A third dog from another Illinois site called Stilwell II was older still, at 10,190 years old. That makes it the oldest known domesticated dog in the Americas. The team concluded that all three dogs were domesticated as they skeletons were complete and unskinned, and so hadn't been butchered for food. They had also been carefully buried, evidence they were valued by their owners. The Stilwell II dog, which probably resembled a small English settler, was under what seemed to be the floor of a living area. It is unclear why it took so long for tame dogs to arrive in the Americas, given that they were domesticated at least 14,000 years ago in Eurasia. By this time, people were already moving into North America from Siberia; there is evidence some reached Chile 18,500 years ago. Geneticists have found signs of at least three waves of migration over the following millennia. There is no evidence that domestic dogs accompanied them. “We don't know if dogs were part of the first waves of immigration to the Americas" says Luc Janssens of Ghent University in Belgium. "It could be so, but no archaeological bones have yet been found." It is "overwhelmingly probable" that some of the early settlers did bring dogs to the Americas, but they may not have had "the time or the spiritual compulsion to bury them", says Pat Shipman of Pennsylvania State University.

    I began working in journalism when I was eight. It was my mother's idea. She wanted me to "make something" of myself, and decided I had better start young if I was to have any chance of keeping up with the competition.

    With my load of magazines, I headed toward Belleville Avenue. The crowds were there. There were two gas stations on the corner of Belleville and Union. For several hours I made myself highly visible, making sure everyone could see me and the heavy black letters on the bag that said THE SATURDAY EVENING POST. When it was supper time, I walked back home.

    "How many did you sell, my boy?" my mother asked.

    "None."

    "Where did you go?"

    "The corner of Belleville and Union Avenues."

    "What did you do?"

    "Stood on the corner waiting for somebody to buy a Saturday Evening Post."

    "You just stood there?"

    "Didn't sell a single one."

    "My God, Russell!"

    Uncle Allen put in, "Well, I've decided to take the Post." I handed him a copy and he paid me a nickel. It was the first nickel I earned.

    Afterwards my mother taught me how to be a salesman. I would have to ring doorbells, address adults with self-confidence, and persuade them by saying that no one, no matter how poor, could afford to be without the Saturday Evening Post in the home.

    One day, I told my mother I'd changed my mind. I didn't want to make a success in the magazine business.

    "If you think you can change your mind like this," she replied, "you'll become a good-for-nothing." She insisted that, as soon as school was over, I should start ringing doorbells, selling magazines. Whenever I said no, she would scold me.

    My mother and I had fought this battle almost as long as I could remember. My mother, dissatisfied with my father's plain workman's life, determined that I would not grow up like him and his people. But never did she expect that, forty years later, such a successful journalist as me would go back to her husband's people for true life and love.

    John, a very thin boy, loved football with all his heart when he was very young. Practice after practice, he eagerly gave everything he had. But being half the size of the other boys, he could only sit on the bench and hardly ever played in games. Even though the son was always on the bench, his father was always standing with cheers and encouraging him.

    When John went to college, he decided to try out for the football team as a “walk-on”. Everyone was sure he could never make the cut, but he did. The coach thought he could provide the other members with the spirit they needed.

    The news that he had survived the cut excited him so much that he rushed to the nearest phone and called his father. His father shared his excitement and was sent season tickets for all the college games.

    It was the end of this last football season. One day John received a telegram and asked one week off. Nobody knew what happened except the coach. The coach said, “Don't plan to come back to the game on Saturday.”

    Saturday arrived, and the game was not going well：When the team was ten points behind, John came back. “Coach, please let me play. I've just got to play today,” said John. The coach pretended not to hear him. But John persisted, and finally feeling sorry for the kid, the coach gave in.

    Before long everyone could not believe their eyes. John was doing everything to fight. The opposing team could not stop him. He ran, he passed and blocked like a star. And at last his team won the game.

    After the game, John looked at the coach, with tears in his eyes, and said, “Well, you knew my dad died, but did you know that my dad was blind?'' John swallowed hard and forced a smile, “Dad came to all my games, but today was the first time he could see me play, and I wanted to show him that I could do it.”

    Still seeking a destination for your weekend break? There are some places which are probably a mere walk away from your college.

    King's Art Centre

    A day at the Centre could mean a visit to an exhibition of the work of one of the most interesting contemporary artists on show anywhere. This weekend tees the opening of an exhibition of four local artists.

    You could attend a class teaching you how to 'learn from the masters' or get more creative with paint—free of charge.

    The Centre also runs two life drawing classes for which there is a small fee.

    The Botanic Garden

    The Garden has over 8, 000 plant species; it holds the research and teaching collection of living plants for Cambridge University.

    The multi-branchedTorch Aloe here is impressive. The African plant produces red flowers above blue-green leaves, and is not one to miss.

    Get to the display house to seeDionaea muscipula, a plant more commonly known as the Venus Flytrap that feeds on insects and other small animals.

    The Garden is also a place for wildlife-enthusiasts. Look for grass snakes in the lake. A snake called 'Hissing Sid' is regularly seen lying in the heat of the warm sun.

    Byron's Pool

    Many stories surround Lord Byron's time as a student of Cambridge University, Arriving in 1805, he wrote a letter complaining that it was a place of "mess and drunkenness". However, it seems as though Byron did manage to pass the time pleasantly enough. I'm not just talking about the pet bear he kept in his roans. He spent a great deal of time walking in the village.

    It is also said that on occasion Byron swam naked by moonlight in the lake, which is now known as Byron's Pool. A couple of miles past Grantchester in the south Cambridgeshire countryside, the pool is surrounded by beautiful circular paths around the fields. The cries of invisible birds make the trip a lovely experience and on the way home you can drop into the village for afternoon tea. If you don't trust me, then perhaps you'll take it from Virginia Woolf—over a century after Byron, she reportedly took a trip to swim in the same pool.

New research into a long-lived tree has shown some of the tricks that have helped it survive for thousands of years. The ginkgo(银杏树) is a huge, slow-growing tree with fan-shaped leaves, native to China, but planted in parks and gardens across the world. Some of the largest ginkgoes are said to be more than 3, 000 years old.

In order to discover how these and other trees can live for so long, scientists from the US and China studied 34 healthy ginkgoes of different ages. The team studied growth rings in each tree's trunk(树干), as well as cells(细胞) from the bark, leaves and seeds. They found that 600-year-old trees were just as healthy as 2-year-olds.

To learn more, the team then looked in detail at the DNA of nine trees aged between three and 667 years old. DNA is the chemical in the cells of plants and animals that holds instructions that tell any living thing how to grow and develop-including what to do at different times in its life At the beginning of a tree's life, DNA instructs the cells in a seedling to divide quickly so the tree grows rapidly. The cells also make special chemicals to help the young plant survive difficult situations, such as disease. As most trees grow older, their DNA tells their cells to divide more slowly (so growth slows down) and to make fewer chemical defenses(防御).

Ginkgoes, however, do things differently. The team found that although their growth finally slows, both young and old trees make protective chemicals." The secret is keeping a really healthy defense system," said researcher Richard Dixon." As ginkgoes age, they show no sign of weakening their ability to defend themselves from things like disease. "Other trees that live for a long time may have the same ability.

For all their defenses, though, ginkgoes cannot live forever--they finally meet with deadly accidents such as fire, disease and storms. While they last, however, these leafy trees are some of the most beautiful trees in the world.
