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.

    A middle-aged man with a long beard was caught by the police for bad behavior and property damage. The man, Bill Wild, checked into a hotel last night, telling the clerk he would pay cash in advance and would be staying for four nights. He then asked her where the nearest store was and she told him it was John-Johns.

    Wild went to the store and bought three gallons of honey and four gallons of chocolate syrup (糖浆). The cashier asked him why he wanted these things and he replied, "I'm trying to become a sweeter person." The cashier smiled at the joke. Wild drove back to the hotel. He opened all bottles and poured them into the bathtub. He added warm water to the mix. He tuned the radio to an opera music station, took off his clothes, jumped into the tub, and started singing loudly with the music.

    Fifteen minutes later, the neighbor phoned the clerk complaining about the noise. The clerk knocked on Wild's door, but he just kept singing. She phoned his room, but he didn't answer. Then she called the police, who arrived quickly. They broke into the room. The floor was covered in water and the bathtub was full of chocolate and honey. "He seemed so nice and friendly. Who'd have thought he was a bathtub-singing nut?" said the clerk. The police said this was the third time that Wild had been arrested for this kind of behavior.

    Suppose you are a visitor in the land of Mongolia, some friends ask you to eat with them. What kind of manners do they want you to have? They want you to give a loud burp (饱嗝)after you finish eating. Burping would show that you like your food. In some countries, if you give a big burp, you are told to say “Excuse me, please”.

    In many places people like to eat together. But in some parts of Polynesia it is bad manners（没礼貌） to be seen eating at all. People show their good manners by turning their backs on others while they eat.

    What are manners like in an East African town? The people try not to see you. They are being polite. You may see a friend. He may not see you at all. If you are polite, you will sit down beside him. You will wait until he finishes what he is doing. Then he will talk to you. Manners are different all over the world. But it is good to know that all manners begin in the same way. People need ways to show that they want to be friends.

    Throughout history scientists have risked their health and their lives in their search for the truth.

    Sir Isaac Newton, the seventeenth century scientist, was very smart, but that didn't stop him from doing some pretty stupid things. In his laboratory in Cambridge he often did the strangest experiments. Once, while testing how light passes through lenses (晶状体), he put a long needle into his eye, pushed it to the back, and then moved it around just to see what would happen. Luckily, nothing long-lasting did. On another occasion he stared at the sun for as long as he could bear, to discover what effect this would have on his sight. Again he escaped suffering permanent damage, though he had to spend some days in a darkened room before his eyes recovered.

    In the 1750s the Swedish chemist Karl Scheele was the first person to find a way to produce phosphorus (磷). He in fact discovered eight more chemical elements including chlorine (氯), though he didn't get any praise for them. He was a very clever scientist, but his one failing was a curious habit of tasting a little of every substance he worked with. This risky practice finally caught up with him, and in 1786 he was found dead in his laboratory surrounded by a large number of dangerous chemicals, any of which might have been responsible for his death.

    Eugene Shoemaker was a respected geologist. He spent a large part of his life studying craters (火山口) on the moon, and how they were formed, and later did research into the comets of the planet Jupiter. In 1997 he and his wife were in the Australian desert where they went every year to search for places where comets might have hit the earth. While driving in the Tanami desert, normally one of the emptiest places in the world, another vehicle crashed into them and Shoemaker was killed on the spot. Some of his ashes (骨灰) were sent to the moon aboard the Lunar Prospector spacecraft and left there — he is the only person who has had this honor.

    At schools across the United States, students often sit down to cafeteria lunches made from processed foods that are high in fat, sodium, and sugar. But kids at Public School(P. S. )216 in Brooklyn have a different dining experience. Principal Donna Neglia reports that her students love eating fresh fruits and vegetables.

    P. S. 216 participated in the Edible Schoolyard Project, a nonprofit program founded by Chef Alice Waters in 1995. The program that Waters created helps public schools across the country start on-site gardens and weave principles of healthy eating into the curriculum. Students grow and maintain crops, harvesting the fruits and vegetables for cafeteria meals.

    Waters expressed her passion for the principles of the farm-to-table movement. She advised schools to connect with the farmers in their area and change their buying practices when planning meals for students.

    Waters has long been inspiring people to care about where their food comes from. In 1993, she put forward the idea of a White House vegetable garden. It was not until 2009 that Michelle Obama started the garden in the backyard of the White House. She and members of the kitchen staff spent hours tending to the garden, often with help from local school children.

    “That gave people a sense that she cared about children and cared about where our food comes from,” Waters said, praising the former First Lady's concern for young people's health. “We are just building this movement, and it is very exciting. ”

    “Through the Edible Schoolyard Project, students also learn about the benefits of healthy eating in the classroom.” Neglia said. “P. S. 216 is teaching kids about careers in the food industry—such as farming and agriculture, nutrition, food safety, and the restaurant business.”

    Similar classes are taking place around the country. So far, the Edible Schoolyard Project has reached more than 1 million students in more than 367 schools. “I'm thinking about the future of the planet,” Waters said. “I'm doing this for our generation.”

    If you're encouraged by the tiny house movement and think 160 square feet is just enough for your needs, you may want to contact the Academy of Construction and Design (ACAD) at IDEA Public Charter School in northeast Washington．

    Students in the program built a micro house with a kitchen, a bathroom, a sleeping loft with space for a queen-size bed and a storage loft, all set on a trailer for mobility. The exterior (外部) of the house was part of a continuous living exhibit in 2015and was moved to the IDEA campus so students could work with builders to complete the interior earlier this year.

    McMahon said the D.C. government's approval to push companies to hire District residents (居民) was at odds with the school system not preparing students for careers in construction, exploring or electrical work. McMahon gathered industry and community leaders to establish ACAD in 2005 and he said 100 percent of the companies he contacted responded positively to the idea, including major firms such as JBG, Clark Construction, Hines Construction and Boston Properties.

    “When students make the connection between what they are learning a potential career, their academics improve dramatically,” said Carol Randolph, chief operating officer of the D.C. Students Construction Trades Foundation. “Some of them who didn't think college was an choice now have a better chance because their classes have become relevant to a job.”

    “We teach them life skills and explain that even if you start as a laborer, there are opportunities to move up quickly,” he said. “We rewrite the story for them and explain that they can work for a few years, make good money, get promoted, and start their own business or go to school with less debts.”

    “Parents and school advisors can be the biggest obstacles because of the negative idea of construction as a blue-collar career,” Karriem said. “I get middle-school advisors on board to talk about the opportunities this education provides. These kids are learning lifelong skills that can help them in other fields, provide them with income and allow them to take care of their homes.”
