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.

    My elder brother Steve, in the absence of my father who died when I was six, gave me important lessons in values that helped me grow into an adult.

    For instance, Steve taught me to face the results of my behavior. Once when I returned in tears from a Saturday baseball game, it was Steve who took the time to ask me what happened. When I explained that my baseball had soared through Mrs. Holt's basement window, breaking the glass with a crash, Steve encouraged me to apologize to her. After all, I should have been playing in the park down Fifth Street and not in the path between buildings. Although my knees knocked as I explained to Mrs. Holt, I offered to pay for the window from my pocket money if she would return my ball. I also learned from Steve that personal property(财产) is a sacred thing. After I found a shiny silver pen in my fifth-grade classroom, I wanted to keep it, but Steve explained that it might be important to someone else in spite of the fact that it had little value. He reminded me of how much I'd hate to lose to someone else the small dog my father carved from a piece of cheap wood. I returned the pen to my teacher, Mrs. Davids, and still remembered the smell of her perfume as she patted me on the shoulder. Yet of all the instructions Steve gave me, his respect for life is the most vivid in my mind.

    When I was twelve, I killed an old brown sparrow in the yard with a BB gun. Excited with my skill, I screamed to Steve to come from the house to take a look. I shall never forget the way he stood for a long moment and stared at the bird on the ground. Then in a dead, quiet voice, he asked, “Did it hurt you first, Mark?” I didn't know what to answer. He continued with his eyes firm, “The only time you should even think of hurting a living thing is when it hurts you first. And then you think a long, long time.” I really felt terrible then, but that moment stands out as the most important lesson my brother taught me.

    Do you ever wonder why trees begin to bud (发芽) earlier in some cities? Scientists finally found the answer but it's not very pleasant. New science suggests a relationship between light pollution and the timing when trees produce buds, which signals the arrival of the spring season.

    Light pollution is defined by the Lighting Research Center as the unwanted consequence of outdoor lighting such as street lights. Excessive (过多的) man-made light at night results in disturbed natural cycles, and also prevents the observation of stars and planets at night. But its effect on the environment goes beyond that.

    By studying some trees, researchers found out that trees that are more exposed to artificial lighting at night bud up to 7.5 days earlier than those at the natural nighttime setting. And they found out that light had a more significant effect than temperature when the buds came out. The early budding may cause problems for insects, which feed on leaves, and the birds which then feed on them in turn. Professor Richard French Constant, who helped lead the research, explained that more than the budding of trees, the study implies the danger to the balance of the ecosystem. “At the moment, caterpillars (毛毛虫) are timed to hatch to make the most of the opportunities to feed on freshly budded leaves, and birds hatch in time to feed on the young caterpillar,” he said.

    Migratory (迁徙的) birds are also negatively affected by light pollution. The glare might confuse them and make them lose their flying sense. The phenomenon might explain why some birds accidentally knock into buildings.

    Such results stress the need to pursue studies that aim to measure the effect of light pollution. If the issue were left to continue, it is estimated that by 2100, spring would begin almost a full month earlier than it does today.

    From ancient stories to modern researches, the label（标签）attached to being left-handed is undeniable. Left-handed people, or "lefties" as they are often called, are generally believed to be good at art — Leonardo da Vinci, Picasso and Michelangelo are all left-handed.

    Our brain is divided into two parts: the left hemisphere(大脑半球)and the right hemisphere. The left hemisphere, linked to logic and analysis, is responsible for the right side of the body. The right hemisphere, linked to creativity and imagination, controls the left side of the body. So, people tend to believe lefties are controlled by the right side of the brain, and are more creative than right-handers. Some also think that lefties may not be as good as right-handers in mathematics and problem-solving skills.

    However; a recent study carried out by scientists from the University of Liverpool in the UK and the University of Milan in Italy proved this theory wrong. The study involved(涉及)more than 2,300 students in Italy aged between 6 and 17 years old. They were asked to complete several mathematical tasks of different levels. It turned out the left-handers outperformed the others when the tasks involved difficult problem-solving. This pattern was particularly clear in male adolescents. However; when it came to simple arithmetic, there was no difference between left-handers and right-handers.

    It was also discovered that those who are "severely" right-handed performed less well in all the experiments compared to "medium" right-handers and left-handers.

    "Taken together, these findings show that handedness does influence abilities to some degree," the study's authors wrote. However, "handedness is just an indirect expression of brain function," wrote psychology professor Giovanni Sala from the University of Liverpool in the UK, the lead author of the study. Sala also noted that only one third of people with a highly-developed right side of the brain are left-handed. It means that there are lots of right-handed people with a similar brain function as left-handers.

    The traditional British pub is part of the scenery of British life. At the last count, there are around 50,000 of them in the UK. The oldest – Ye Olde Fighting Cocks in St. Albans – was set up in about 793.

    Because of their abundance, the names pubs take are designed to be memorable, but more than that, they are designed to be visual. Outside any traditional pub worthy of its title, you'll find a hanging signboard with an unusual and uncommon illustration(插图) that represents the name of the business. The practice is so well established that even new pubs copy it. But why do they exist at all?

    The first British pub signs were created in the 12^th century and were simple representations of beer containers and other brewing-related equipment used to tell passersby that establishments sold beer. This was Britain in the dark ages, when education was in short supply. Since most of the population was unable to read, pub signs were used to inform would-be customers that they could find a drink inside.

    The earliest uses of pub names would reference the sign directly. People would appoint to meet at "the sign of the Eagle and Child" rather than at "the Eagle and Child".

    Today the tradition remains unchanged largely out of respect for the past, but many pub signs do have some functionality. Remote country pubs often use signboards to point the way to their doors. It's a part of British culture that's rapidly disappearing – more than 20,000 pubs have closed since 1980 – but for now there are still more than enough. You can take a moment to appreciate the history and symbolism behind a pub's sign the next time you see one.

I've spent over a year in India, and in those 365 plus days, I've learned a lot about getting around Indian cities. My biggest lessons have been learned through being cheated, particularly by taxi and rickshaw (人力车) drivers, but that doesn't mean those are bad ways to travel, as long as you know what you're doing. Below are the best ways to get around the city of Delhi, India, and tips for how to keep from being the victim of scams (欺骗).

Taking taxis is a great way to get around the city of Delhi and chances are, if you arrive in Delhi by plane, as soon as you make it through customs, you'll be swarmed by Indian taxi drivers. At the Delhi airport, be sure to arrange for a taxi to your hotel at one of the two Delhi Traffic Police Taxi Booths. One is inside the airport, and one is outside. The key is to make sure to go to a booth run by the police, rather than by independent taxi drivers.

Rickshaws are one of my favorite ways to get around Indian cities, in part because it's how the locals often travel. Auto­rickshaws are more common, but bicycle rickshaws are still used in Old Delhi. If you do have a chance to take a bicycle rickshaw, you should do it at least once for a unique experience that should only set you back about 15 rupees. Auto­rickshaw rates around Delhi range between 30 and 80 rupees, depending on distance.

If you really want to travel around Delhi like the locals, take a public bus. Indian buses become very crowded and most do not have air conditioning. They are, however, very cheap. A bus trip won't set you back any more than 15 rupees, as long as you stay within the city limits. Since Indian buses get so crowded, try to board the bus at the start of the route so you can get a seat.

The train is a great way to get around within the city of Delhi. Fares are reasonable, between six and 22 rupees. All departure announcements are in both Hindi and English, and tokens can be purchased for between 6 and 22 rupees.
