The stories we share with one another are important. They show wisdom and provide inspiration. They are important to our development. But sometimes people choose not to tell.

    Considering the negative effects of not sharing a story in the news, people are wondering if public health officials are holding back too much information about the recent outbreak of Ebola.

    There is a danger in holding back stories that ought to be told. Bobette Buster said it like this, “The fact is, history has shown us that stories not told can become like a dangerous genie (妖怪) left in a bottle. When they are finally uncorked(透漏), their power to destroy is set free."

    There are a number of reasons why we hide parts of our story: they often show our weaknesses or expose our disadvantages; they require courage and strength to share; and of course, there are some stories that should be kept secret—especially those that embarrass someone else.

    Most of us have two selves: the one we display on the outside and the one we actually are on the inside. And the better we get at hiding the stories that show our true selves, the more damage we may be causing to ourselves and to others.

    Honesty and openness is important: It proves we are trustworthy. It displays we are human. We are not perfect or better. It highlights the importance of hard work and personal development. Hard work may not allow us to overcome our disadvantages completely. But with hard work, we do not have to be restricted to our mistakes.

    Does this mean we admit every weakness, every disadvantage, and every secret regret to everybody we meet? No, of course not. There is a time and a place and a certain level of relationship necessary for some stories to be told in an appropriate manner.

    Orville Wright was born on August 19, 1871 in Dayton, Ohio, USA and died on January 30, 1948. Together with his brother, Wilbur, he was the first airplane builder. The brothers created the first controlled, powered and heavier-than-air human flight.

    His parents were Milton Wright and Susan Catherine Koerner and besides the two famous brothers they had five children. One day after a trip his father brought as a gift a small helicopter. The kids loved it and as they played daily with it after a while it broke. The brothers managed to create a new one. Wright even let go his plans of attending Yale. He spent his time helping his ill mother and reading in his father's library.

    In 1884 the family decided to move to Dayton and they remained there until the 1870's. A printing press was built by the two and Wilbur was an editor. In 1892 they started being fascinated by the aeronautical （航空的） events of that time. Then they started to create an airplane and Wilbur was considered the head of the team. They were the inventors of “three axis-control”, which permitted the pilot to steer the aircraft's balance.

    In 1900 they had their first attempts to make a functional glider（滑翔机）— of course it didn't have a pilot. After three years they thought of introducing an engine to the glider. At first, their patent(专利) application was refused in 1903, but after one year it was accepted.

    Orville's first flight lasted 12 seconds and had 36.5 meters. He was responsible with the public shows near Washington in the United States. On September 9, 1908 his flight was 62 minutes and 15 seconds long and the success was huge.

    Of all nature's disasters, forest fires are often considered the most frightening. Moving at lightning speed, huge walls of flames can burn acres of land in just a few minutes. And although technology, including the use of fire-retardant chemicals, has greatly helped the fight against forest fires, they still do great damage.

    According to the National Interagency Fire Center, the fire season last year was the worst on record in terms of the number of fires and acres burned. There were 96. 385 fires and 9.873429 acres affected by fire in a year that was 125% more destructive(毁灭性的) than the10-year average. These fires cost the federal government $1.5 billion to fight, and this figure does not include the money spent by local and state governments as part of the effort.

    Fires in the southern states represented half of the national total last year with Texas, Oklahoma and Arkansas being home to a usually high amount of activity. Wildfire has also taken place in Western states such as California, Colorado and Alaska throughout the past 10 years.

    It is said that two-thirds of forest fires are started accidentally by people. Almost one quarter are purposely set, while lighting causes 10%.

    Forest fires can have advantageous effects. Charcoal(木炭) enriches soil and some plant species(种类) grow well after fire. The cones of the jack pine tree, for example, will not spread their seeds unless there is heat. Douglas fir trees grow best in open sunlight areas after fire.

    Located in the checkroom in Union Station as I am, I see everybody that comes up the stairs.

Harry came in a little over three years ago and waited for the passengers from the 9:05 train.

    I remember seeing Harry that first evening. He wasn't much more than a thin, anxious kid then and I knew he was meeting his girl and that they would be married twenty minutes after she arrived. The passengers came up and I had to get busy. I didn't look toward the stairs again until it was nearly time for the 9:18 train and I was very surprised to see that the young fellow was still there.

    She didn't come on the 9:18 either, nor on the 9:40, and when the passengers from the 10:02 had all arrived and left, Harry was looking pretty desperate. He showed me the telegram he'd received: ARRIVE THURSDAY. MEET ME STATION. LOVE YOU. MAY.

    Harry met every train for the next three or four days, but in vain.

    Then came yesterday. I heard a cry and found that it was from Harry. He grabbed a girl who was small and dark. For a while they just hung there to each other laughing and crying and saying things without meaning. She'd say a few words like, "It was the bus station I meant" and he'd kiss her speechless and tell her the many things he had done to find her. What apparently had happened three years before was that May had come by bus, not by train, and in her telegram she meant "bus station," not "railroad station." She had waited at the bus station for days and had spent all her money trying to find Harry. Finally she got a job typing.

    "What?" said Harry. "Have you been working in town? All the time?"

    She nodded.

    "Didn't you ever come down here to the station?" He pointed across to a magazine stand. "I've been there all the time. I own it. I've watched everybody that came up the stairs."

    She began to look a little pale. Pretty soon she looked over at the stairs and said in a weak voice, "I never came up the stairs before. Harry, for three years, for three solid years, I've been right over there working right in this very station, typing, in the office of the stationmaster."

Plastic-Eating Worms

    Humans produce more than 300 million tons of plastic every year. Almost half of that winds up in landfills(垃圾填埋场)，and up to 12 million tons pollute the oceans. So far there is no effective way to get rid of it, but a new study suggests an answer may lie in the stomachs of some hungry worms.

    Researchers in Spain and England recently found that the worms of the greater wax moth can break down polyethylene, which accounts for 40% of plastics. The team left 100 wax worms on a commercial polyethylene shopping bag for 12 hours, and the worms consumed and broke down about 92 milligrams, or almost 3% of it. To confirm that the worms' chewing alone was not responsible for the polyethylene breakdown, the researchers made some worms into paste(糊状物) and applied it to plastic films. 14 hours later the films had lost 13% of their mass--apparently broken down by enzymes(酶)from the worms' stomachs. Their findings were published in Current Biology in 2017.

    Federica Bertocchini, co-author of the study, says the worms' ability to break down their everyday food-beeswax--also allows them to break down plastic "Wax is a complex mixture, but the basic bond in polyethylene, the carbon-carbon bond, is there as well, "she explains. "The wax worm evolved a method or system to break this bond. "

    Jennifer Debruyn, a microbiologist at the University of Tennessee, who was not involved in the study, says it is not surprising that such worms can break down polyethylene. But compared with previous studies, she finds the speed of breaking down in this one exciting. The next step, DeBruyn says, will be to identify the cause of the breakdown. Is it an enzyme produced by the worm itself or by its gut microbes(肠道微生物)?

    Bertocchini agrees and hopes her team's findings might one day help employ the enzyme to break down plastics in landfills. But she expects using the chemical in some kind of industrial process-not simply "millions of worms thrown on top of the plastic."

    Whenever we're introduced to strangers, we make snap decisions about them according to our first impressions. Are they attractive or how much do they earn?

    For most Brits, simply asking someone how much they're worth' financially is considered very impolite. Thankfully, most people are kind enough to drop several hints (暗示)about their relative wealth or successful careers They always post on social media about flying to a meeting for work. They're always wearing clothes with labels big enough to silently scream about how rich they are and how well they're doing.

    It's a worrying trend, and I'm not immune to it. I've felt the warm happiness of knowing I earned more than somebody, and the baseless grey irritation of knowing that I earn less than another. I've checked into places while I know full well that anybody reading it will get jealous.

    It seems as though self-worth is increasingly being tied to the careers we choose and the money we earn. A study in 2013, for example found that nearly 17% of unemployed Americans were depressed compared to almost 6% of those who had a permanent job.

    We need to stop placing so much value on what a person earns. Don't get me wrong-being ambitious is not a fault, and achievements should always be celebrated. But when a person uses their success to judge you negatively it becomes a problem.

    If you want to know what you're really worth, here's a tip: It doesn't have anything to do with your bank account. It's about how many times you've been there for your friends. It's how many times you've been kind to a stranger It's every time you did something unselfish, or told your partner you loved him/her, or treated someone with respect no matter where they were in their own life.
