On Sunday, May 25th, 2014, India's Malavath Poorna, became the youngest female to climb to the summit of the world's highest peak—Mount Everest. The 13-year-old girl surpassed (超越) the previous record holder, Nepal's Nima Chemji Sherpa, who accomplished the same achievement in 2012, at the age of 16.

    Unlike many young climbers who come from wealthy families, Malavath comes from a poor farming family living in a small village named Pakala in southern India.

    Most Pakala girls have never seen the inside of a school all their lives. Malavath is one of the fortunate ones that managed to realize their dreams thanks to Swaeroes, a welfare organization whose mission is to help India's poor children reach their full potential. They helped enroll (使入学) the young girl in a nearby boarding school. Then about nine months ago, Swaeroes provided her with the opportunity to achieve this dream by offering mountaineering training. Not one to pass up (错过) an exciting adventure, the athletic girl signed up.

    At the end of the two-week period, only two youngsters were selected for the dangerous climb—Malavath was one of them!

    Then came the big day. On April 15th, 2014, Malavath and 16-year-old Anand Kumar along with their guide Shekhar Babu and a team of Sherpas (夏尔巴人) began the dangerous 8,848-meter trek (艰苦跋涉). While most climbers attempt the peak from the slightly easier Nepalese side, this team had to go via the harder Tibetan side. That's because the government of Nepal does not allow anyone younger than 16 to climb up the route.

    It was not easy. In fact, Malavath was sent back to the base camp after she experienced altitude sickness when she got to the advanced base camp set up at an altitude of 6,400 meters. However, the youngster returned three days later, and insisted on continuing. It took 52 days, but on May 25th, 2014, Malavath, who made it to the summit a few minutes ahead of 16-year-old Anand, proudly raised her country's flag at the top of the world. The young girl hopes that her achievements will inspire poor girls all over the world to try to achieve their dreams.

    Taking on the task of producing a short movie might seem like an impossible feat, but if you can assemble a good team and if you break down each stage of production into small blocks of tasks, you'll come to realize that producing a small-scale movie isn't too bad. Just follow these steps and you'll be on your way to Kevin Smith-like fame in no time.

    Assemble a production crew. If you run out of friends or people you can get to work for screen credit, offer people “points”, which is a percentage of the movie profits.

    Get a director of photography. You need someone who knows a lot about films cameras to make the movie come out right. Local film schools are the best place to find them.

    Assemble the props and costumes. Costume shops and local theater groups can definitely help you here. But you can also borrow from friends and family or check out thrift stores for bargains.

    Choose filming locations. Make sure you have permission from the owners of the property you choose to film on.

    Get the film processed. Find the right processor with the help of your director of photography. You may need to send the film to Los Angeles for this.

    Edit the film. You need to find someone who can transfer your film to video and arrange the completed scenes in the right order. You can likely find one in the same place as your director of photography,

    Obviously, this is just a basic overview—the thing about producing a short independent movie is that the whole process is unpredictable. You can only set yourself up for the basics, but as long as you know things will go wrong every day, at least you'll be prepared to deal with the difficulties.

    One of the most firmly established idea of manliness is that a real man doesn't cry. Although he might shed a tear at a funeral, he is expected to quickly regain control. Sobbing openly is for girls. One study found that women cry significantly more than men do—five times as often, on average, and almost twice as long per period.

    Historically, however, men routinely wept, and no one saw it as shameful. For example, in the Middle Ages, knights cried purely because they missed their girlfriends. In The Knight of the Cart, no less a hero than Lancelot weeps at a brief separation from Guinevere. There's no mention of the men in these stories trying to restrain or hide their tears. They cry in a crowded hall with their heads held high. Nor do their companions make fun of this public crying; it's universally regarded as an admirable expression of feeling.

    So where did all the male tears go? The most obvious possibility is that this shift is the result of changes as we moved from an agricultural society to one that was urban(城市的) and industrial. In the Middle Ages, most people spent their lives among those they had known since birth. If men cried, they did so with people who would sympathize. But from the 18th to 20th centuries, the population became increasingly urbanize, and people were living in the midst of thousands of strangers. Furthermore, changes in the economy required men to work together in factories and offices where emotional expressions and even private conversations were discouraged as time wasting.

    Yet human beings weren't designed to swallow their emotions, and there's reason to believe that holding back tears can be harmful to your well-being. Research from the 1980s has suggested a relationship between stress-related illnesses and inadequate crying. Weeping is also, somewhat related with happiness and wealth. Countries where people cry the most tend to be richer and more confident.

    Experts like to say the best form of exercise is whatever kind you'll actually do. But that may not always be the case; new research finds that people who combine exercise with their social lives may be at an advantage over solitary（独自） exercisers. Tennis, badminton and soccer are all better for longevity(长寿) than cycling, swimming, jogging or gym exercise, according to the research.

    The study was based on data from about 8,500 adults who were part of the Copenhagen City Heart Study. They completed a health and lifestyle questionnaire, which included questions about type and frequency of physical activity, and were monitored by the researchers for around 25 years, a period during which about 4,500 of the subjects died.

    Tennis came out on top in the research. Compared with people sitting all day, those who reported playing tennis as their main form of exercise could expect to add 9.7 years to their life time, followed by badminton (6.2 years), soccer (4.7 years), cycling (3.7 years), swimming (3.4 years), jogging (3.2 years) and health-club activities (1.5 years).

    Tennis likely took the top spot because "it's very interactive," says study co-author Dr. James O'Keefe, a physician at Saint Luke's Mid America Heart Institute. "At every point you're talking. It's just a very natural way to emotionally bond with people, besides getting your exercise." But he adds that the study may not have been able to fully account for the fact that wealthier, better-educated people—who tend to be healthier to begin with—may be more likely to play tennis.

    Activities like running and weight lifting still extend your life and offer plenty of other health benefits. But for the best possible benefits, O'Keefe says gym-goers may want to consider combining those workouts with activities that foster social connection.

    O'Keefe, whose exercise typically includes running and weight lifting, says he's even changed his own behavior because of the study: he and his family have taken up badminton.

    "You can't play badminton without feeling like a kid again," he says. "It's just pure fun."

    You probably know who Marie Curie was, but you may not have heard of Rachel Carson. Of the outstanding ladies listed below, who do you think was the most important woman of the past 100 years?

    Jane Addams (1860-1935)

    Anyone who has ever been helped by a social worker has Jane Addams to thank. Addams helped the poor and worked for peace. She encouraged a sense of community(社区) by creating shelters and promoting education and services for people in need. In 1931, Addams became the first American women to win the Nobel Peace Prize.

    Rachel Carson (1907-1964)

    If it weren't for Rachel Carson, the environmental movement might not exist today. Her popular 1962 book Silent Spring raised awareness of the dangers of pollution and the harmful effects of chemicals on humans and on the world's lakes and oceans.

    Sandra Day O'Connor (1930-present)

    When Sandra Day O'Connor finished third in her class at Stanford Law School in 1952, she could not find work at a law firm because she was a woman. She became an Arizona State Senator(参议员) and in 1981, the first woman to join the US Supreme Court（高等法院）. O'Connor gave the deciding vote in many important cases during her 24 years on the top court.

    Rosa Parks (1913-2005)

    On December 1, 1955, in Montgomery, Alabama, Rosa Parks would not give up her seat to a white passenger. Her simple act landed Parks in prison. But it also set off the Montgomery bus boycott. (抵制行动) It lasted for more than a year, and kicked off the civil-rights movements. "the only tired I was, was tired of giving in." said Parks.

    The fiddler crab (蟹) is a living clock. It indicates the time of day by the colour of its skin, which is dark by day and pale by night. The crabs changing colour follows a regular twenty-four hour plan that exactly matches the daily rhythm (节奏) of the sun.

    Does the crab actually keep time, or does its skin simply answer to the sun's rays, changing colour according to the amount of light strikes it? To find out, biologists kept crabs in a dark room for two months. Even without daylight, the crab's skin colour continued to change exactly on time.

    This characteristic(特性) probably developed gradually in answer to the daily rising and setting of the sun, to help protect the crab from sunlight and enemies. After millions of years it has become completely regulated (受控制) inside the living body of the crab.

    The biologists noticed that once each day the colour of the fiddler crab is especially dark, and that each day this happens fifty minutes later than on the day before. From this they discovered that each crab follows not only the rhythm of the sun but also that of the tides (潮水). The crabs period of greatest darkening is exactly the time of low tide on the beach where it was cought!
