It is probably the strangest sport anyone has ever invented. And at first sight, it looks like the easiest. Competitors have to do two things. The first is to stand still. The second is to place their hands anywhere on the body of a car, and keep it there.

    This is where things start getting difficult. Lots of people are doing the same thing. And the winner of the “handstand” contest is the person who can carry on doing it for the longest time. That person gets to own the car.

It still seems to be an easy thing to do. At the beginning it is. Anyone can stand still. But when the contest has been going for four or five days, standing still seems like the most difficult job in the world . And keeping the hand in place over this time becomes an act of serious attention. After a few days, the hand seems to belong to someone else—-someone who wants to go home and get some sleep.

    Competitors are allowed to take a five-minute break every hour to eat, drink or do whatever else is necessary. No one is allowed to lean on the car for support. Winners need to be able to show great powers of attention. They also need to be able to develop special skills.

    Maybe the popularity of the “handathon” is due to the fact that it is not necessary to be a trained athlete to enter. Competitors in the Longview handathon certainly don't seem to do much preparation. Most say they will prepare by “getting lots of sleep”. Others say they will “eat healthy food” or “pray for success”.  The whole event gives ordinary people the chance to do something interesting and win something in the end.

    Handathons are competitions, but there is little rivalry (竞争) between competitors. They help each other out and keep each other's spitits up. People who drop out early return with food, drink and encouragement.

    Universities are doing everything they can to become a green campus. But there are also items students can do to make your campus more eco-friendly.

1）Recycle everything, especially paper!

    There is a large amount of paper a college student goes through every term.{#blank#}1{#/blank#} We know that these things can't be avoided, but the way you handle the use of all the paper can really help create a better green campus.

2）Buy green.

    {#blank#}2{#/blank#} Paper, cleaning products and water are products that can be bought as recycled goods. They're slightly more expensive than the normal products, but it's worth it to make a green campus.

3）Walk and bike to school.

    Most campuses, especially those that are trying to become a more eco-friendly campus, have pretty good public transit (公共交通系统).{#blank#}3{#/blank#} Walking or biking will help make your campus a green university.

4） {#blank#}4{#/blank#}

    A water bottle can be refilled at any water fountain and can easily be drunk in class or while riding a bike. This will save the environment by decreasing the amount of plastic waste on your campus.

5）Buy used clothing.

    It is usually thought of as something to do to save money. {#blank#}5{#/blank#} Recycling clothes minimizes the use of resources to make clothing and puts a dent in the problem of worldwide sweatshops.

A. Carry a water bottle.

B. It is also good for the environment!

C. Buy recycled goods as much as possible.

D. Paper made of this kind of wood is much stronger.

E. On top of that, almost all universities are pedestrian (步行者) friendly.

F. It includes class notes, term papers, student newspapers and so on.

G. Universities call on all the students to learn to recycle all the waste paper.

    Diamonds are considered the most famous and valuable jewel in the world. The precious stone for its great value is believed to be the symbol of wealth. Diamonds were made as a result of great volcanic beat and pressure. When a volcano is active, it sometimes explodes and causes great damage to the nearby towns.

    However, at the same time of such a disaster, diamonds were pushed towards the surface of the earth by a number of great volcanic explosions millions of years ago. Thus, it may be very likely to find a diamond after a volcanic eruption. Besides, diamonds are also found among the sand and stones of certain river beds, and in a few places on the floor of the sea, for they were washed down the mountain sides by the rain.

    Diamonds are very rare. There are not many places that produce such precious things in the world. During the last century adventurers from Europe went to Brazil, because they had heard that there were diamonds in the River Amazon. Many of these early diamond miners died of illness or were lost forever in the great forests. But some returned home rich.

    The earliest known diamonds were found in India many centuries ago. The most recent and exciting discoveries have been made in eastern Russia. But most of the world's diamonds now come from the Congo, from Tanzania-which has the largest diamond mine in the world and also from South Africa.

    In 1863, the great novelist Jules Verne wrote a novel called Paris in the Twentieth Century. In the book he used the full power of his great ability to forecast the coming century. Unfortunately, the manuscript (手稿) was lost until his great-grandson happened to discover it lying in a safe where it had been carefully locked away for almost 130 years. Realizing what a treasure he had found, he arranged to have it published in 1994, and it became a bestseller at once.

    Back in 1863, kings still ruled the ancient world in Europe, with so many poor people working in the fields. And steam power was just beginning to change the world. But Verne predicted that Paris in 1960 would have glass skyscrapers, air conditioning, TV, high-speed trains, gas-powered vehicles, and even something similar to the Internet. Verne described life in modem Paris almost without any mistakes.

    Just two years later Verne made another amazing prediction. He wrote From the Earth to the Moon, in which he predicted the details of the task that sent several astronauts to the moon 100 years later in 1969. He correctly predicted the size of the space capsule, the number of astronauts who would carry out the task, the weightlessness that the astronauts would experience, and the final landing in the ocean.

    How was Jules Verne able to predict 100 years into the future successfully? Although he was not a scientist himself, Verne often turned to scientists, asking them questions about their opinions of the future. He collected a vast amount of information about the great scientific discoveries of his time. Verne realized that science would make it possible for many amazing things to appear in the future. The secret of his successful prediction was his belief in the power of science to change society.

    In October, I told the eight-year-olds in the class I teach in Pompton Lakes, New Jersey, about my plan. "Since all of you have done extra jobs around the house to earn some money," I said. "Then we'll buy food for a Thanksgiving dinner for someone who might not have a nice dinner otherwise."

    I watched them while they walked up and down the supermarket. "Flowers!" Kristine cried. The group rushed toward the holiday plants.

    "You can't eat flowers."——It was more sensible(明智的) to use any extra money to buy something that could be transformed(转换，转变) into meals.

    "But Mrs. Sherlock," came the begging voice, "we want flowers."

    Defeated finally, I put a pot of "funny" purple(紫色的) mums in the cart full of foods. "She'll like this one," the children agreed.

    An organization had given us the name and address of a needy grandmother who had lived alone for many years. We finally pulled up in front of a small house. A slightly built woman with a weary face came to the door to welcome us.

    My little group ran to get the food. As each box was carried in, the old woman kept on saying "Thanks"—much to her visitors' pleasure. When Amy put the mums on the counter, the woman seemed surprised. She's wishing it was a bag of flour(面粉), I thought.

    We returned to the car. As we fastened our seat belts, we could see the kitchen window. The woman inside waved goodbye, then turned and walked across the room, past the turkey, past the goods, straight to the mums. She put her face in their petal. When she raised her head, there was a smile on her lips. She was transformed before our eyes.

    The children were quiet. At that moment, they had seen for themselves the power they possessed(拥有) to make another's life better. The children had sensed(感到) that sometimes a person needs a bunch of funny purple flowers on a dark November day.

    For those concerned about wrinkly old skin, it might be a creative solution: an elastic(有弹性的) “second skin” that can be smoothed on to make aged tissue look more youthful.

    The wearable film, developed at the Massachusetts Institute of Technology (MIT), has shown promise in a series of small experiments where it was applied to wrinkles, under-eye bags and areas of dry skin. When applied to the face or body, the thin, transparent layer sticks to the skin and supports the tissue, making it look and behave like younger skin, its producers claim.

    “What we've been able to do is create a cream that you can put on the skin, and then when it's on the skin it can actually form, essentially, an elastic second skin,” said Bob Langer, who led the research. Tests in the lab found that the polymer film (高分子膜), which is only 70 thousandths of a millimeter thick, reduced the appearance of wrinkles and under-eye bags, and helped keep moisture (水分) in areas of dry skin.

    The layer is designed to be applied in the morning, then peeled off at night, In previous studies, the second skin withstood normal daily wear, and the stresses and strains of exercise and swimming, without falling off or causing irritation. It also survived exposure to rain.

    “It's something you can wear for a whole day or longer, depending on the physical forces that get applied to the area where it is worn, "said Daniel Anderson, who helped develop the product at MIT. “You can't tell you're wearing it.”

    While normal cosmetics can mask imperfections on the skin, the new coating changes the way skin behaves by giving it the elasticity of young skin. It was developed with help from two companies.
