“I Went Skydiving at 84!”

As a young girl growing up in the 1930s, I always wanted to fly a plane, but back then it was almost unheard of for a woman to do that. I got a taste of that dream in 2001,when my husband arranged for me to ride in a hot air balloon for my birthday. But the experience turned out to be very dull. Around that time, I told my husband that I wanted to skydive. So when our retirement community（社区）announced that they were having an essay competition and the topic was an experience of a lifetime that you wanted to have, I decided to write about my dream.

In the essay, I wrote about my desire to skydive, stating George Brush Sr. did it at age 80. Why not me? I was just 84 and in pretty good health. A year went by and I heard nothing. But then at a community party in late April 2009, they announced that I was one of the winners. I just couldn’t believe it. Inspired by this， I decided to realize my dream, even though some of my family members and my doctor were against it.

On June 11, 2009, nearly 40 of my family and friends gathered in the area close to where I would land while I headed up in the airplane. My instructor, Jay, guided me through the experience. The plane was the noisiest one I had ever been in, but I wasn’t frightened—I was really just looking forward to the experience. When we reached 13,000 feet, Jay instructed me to throw myself out of the plane. When we first hit the air, the wind was so strong that I could hardly breathe. For a second I thought, “What have I gotten myself into?” But then everything got calmer. We were in a free fall for about a minute before Jay opened the parachute（降落伞）, then we just floated downward for about five minutes. Being up in the clouds and looking at the view below was unlike anything I have ever felt—much better than the hot air balloon. I was just enjoying it.

Skydiving was really one of the greatest experiences of my life. I hope other people will look at me and realize that you don’t stop living just because you are 84 years old. If there’s something you want to experience, look into it. If it’s something that is possible, make it happen.

    The world’s first plastic magnet (磁性) to work at room temperature has passed the elementary test of magnetism. Its creators at the University of Durham in the UK have used it to pick iron filings (铁屑) from a laboratory bench.

    In 2001, chemists from the University of Nebraska-Lincoln claimed to have created the world’s first plastic magnet, but it only worked below 10 Kelvin (开氏温度). Other researchers have made plastic magnets, but generally they only function at extremely low temperatures, or their magnetism at room temperature is too weak to be business use.

    So the Durham team can claim to have made the first plastic magnet that could be used in everyday products. One of the most likely applications is in the magnetic coating of computer hard discs, which could lead to a new generation of high-capacity discs.

    Jerry Torrance, a material scientist who is an adviser to some of the world’s largest electronics and engineering companies, including IBM, describes the work as “a great scientific breakthrough”. However, he says that practical applications are probably still a long way off.

    At first the new polymer (聚合物) showed little sign of magnetism, and after three months the researchers had reached the point where they felt that trying to induce (诱发) magnetism in this polymer was a waste of time. “Just as we were about to give up and try a different way, we decided to check the samples for a last time,” says Sean Giblin.

    It was a fortunate decision, because over the months the original polymer had developed magnetic characteristics. Further groups of polymer proved its magnetism and ruled out the possibility that the magnetism had been caused by pollution. In addition, X-ray diffraction data (衍射数据) showed an increase in the straight line of the polymer chains over three months, which probably accounts for the increase in magnetism.

    Although the polymer’s magnetism is weak compared with metal magnets, the researchers are confident that they can improve it. And in addition to computer hard discs, the team thinks that plastic magnets could have important medical applications because organic magnetic materials are less likely to be rejected by the body.

64. The plastic magnets made by the chemists from University of Nebraska-Lincoln and other researchers couldn’t be used in everyday products because        .

    A. they didn’t pass the elementary test of magnetism

    B. they couldn’t pick up iron filings from a laboratory bench

    C. they wouldn’t work at room temperature

    D. they could only be used at high temperature

65. The increase in magnetism over the months is probably caused by        .

    A. checking the samples             B. a wise decision

    C. pollution

    D. the increase in the straight line of the polymer chains

66. The plastic magnets could be used        .

    A. to compare with the metal magnets

    B. to coat computer hard discs

    C. to produce medicine

    D. to lower the temperature

    A. The Birth of Practical Plastic Magnet

    B. The World’s First Plastic Magnet

    C. A Fortunate Decision

    D. The Applications of Plastic Magnets

  Professor Reason recently persuaded 35 people to keep a diary of all their absent-minded actions for two weeks. When he came to analyze their embarrassing errors, he was surprised to find that nearly all of them fell into a few groups.

    One of the women, for instance, on leaving her house for work one morning threw her pet dog her earrings and tried to fix a dog biscuit on her ear. “The explanation for this is that the brain is like a computer,” explains the professor. “People programme themselves to do certain activities regularly.” It was the woman’s custom every morning to throw her dog two biscuits and then put on her earrings. “But somehow the action got reversed（颠倒）in the programme.” About one in twenty of the incidents the volunteers reported were these “programme assembly failures.”

   Twenty percent of all errors were “test failures” — mainly due to not verifying the progress of what the body was doing. A man about to get his car out of the garage passed through the back yard where his garden jacket and boots were kept, put them on — much to his surprise. A woman reported, “I got into the bath with my socks on.”

   The commonest problem was information “storage failures”. People forgot the names of people whose faces they knew, went into a room and forgot why they were there, mislaid something, or smoked a cigarette without realizing it.

   The research so far suggests that while the central processor of the brain is liberated from second-to-second control of a well-practiced routine, it must repeatedly switch back its attention at important decision points to check that the action goes on as intended. Otherwise the activity may be gotten by another frequently and recently used programme, resulting in embarrassing errors.
