“One thing I enjoy about my job is that I can work on something that is actually active,” says Game McGimsey, an American volcanologist (火山学家). Part of his job includes keeping an eye on Alaska's many active volcanoes and giving people a heads-up when a volcano might erupt (喷发).

    Like most jobs in the sciences, volcanology requires a lot of education. McGimsey received an undergraduate degree in geology at the University of North Carolina, then landed an internship (实习期) with a geologist at the USGS (美国地质勘探局) whose area of expertise was volcanoes. After earning a graduate degree at the University of Colorado, McGimsey accepted a job with the USGS and has been with the Alaska Volcano Observatory for 25 years.

    Volcanoes can influence the world in ways we might not think about. For example, on Dec. 15, 1989, a 747 jetliner (a large airplane) flew through a thick ash (灰) cloud produced by Mount Redoubt, an Alaskan volcano that hadn't erupted in 25 years. The ash caused all four engines to die, and the plane's electronics went dead.

    “The plane was within several thousand feet of flying into the mountains below when the pilots got a couple of the engines restarted and landed safely in Anchorage,” McGimsey says. It cost nearly $80 million to repair the damage to the plane.

    Such situations show just how dangerous volcanoes can be. However, volcanologists know the risks and are prepared to protect themselves.

    “There is certainly a higher danger level in volcanology than some other jobs,” McGimsey admits. “We understand how serious the danger is, and we don't like taking unnecessary chances. We avoid getting too close to an erupting volcano, because it's not worth injury or death simply to get a rock or a photograph.”

    Parents and kids today dress alike, listen to the same music, and are friends. Is this a good thing? Sometimes, when Mr. Ballmer and his 16-year-old daughter, Elizabeth, listen to rock music together and talk about interests both enjoy, such as pop culture, he remembers his more distant relationship with his parents when he was a teenager.

    “I would never have said to my mom, 'Hey, the new Weezer album is really great. How do you like it?'” says Ballmer. “There was just a complete gap in taste.”

    Music was not the only gulf. From clothing and hairstyles to activities and expectations, earlier generations of parents and children often appeared to move in separate orbits.

    Today, the generation gap has not disappeared, but it is getting narrow in many families. Conversations on subjects such as sex and drugs would not have taken place a generation ago. Now they are comfortable and common. And parent-child activities, from shopping to sports, involve a feeling of trust and friendship that can continue into adulthood.

    No wonder greeting cards today carry the message, “To my mother, my best friend.”

    But family experts warn that the new equality can also result in less respect for parents. “There's still a lot of strictness and authority on the part of parents out there, but there is a change happening,” says Kerrie, a psychology professor at Lebanon Valley College. “In the middle of that change, there is a lot of confusion among parents.”

    Family researchers offer a variety of reasons for these evolving roles and attitudes. They see the 1960s as a turning point. Great cultural changes led to more open communication and a more democratic process that encourages everyone to have a say.

    “My parents were on the 'before' side of that change, but today's parents, the 40-year-olds, were on the 'after' side,” explains Mr. Ballmer. “It's not something easily accomplished by parents these days, because life is more difficult to understand or deal with, but sharing interests does make it more fun to be a parent now.”

    A new study suggests a simple getting-to-know-you exercise might improve classroom relationships. The teacher-student relationship affects every aspect of the educational experience. When students don't feel safe and respected by their teacher, they are less likely to devote themselves to their education. And when teacher feel distanced from their students, it is nearly impossible to walk into the classroom each day actively, let alone encourage motivation or investment in students.

    Hunter Gehlbach, a professor, explained that his research is primarily concerned with social perspectivetaking(换位思考), or the ability to understand what drives the people around us. As he explained, "My focus is classrooms and social perspective-taking--figuring out the thoughts and feelings of others seems important. We want teachers to be able to engage in this process and figure out the thought process of students as much as possible, in order to understand where and why they are making mistakes."

    Gehlbach and his colleagues gave 315 students and 25 teachers a "getting-to-know-you" survey of 30 items at the beginning of a school year. The researchers matched similarities between the teacher and the student, and then showed those similarities to the teachers and students. Five weeks later, the researchers returned to start a more indepth survey of both students and teachers, and to measure their opinions of their relationships and the classroom experience as a whole. The second survey showed that when teachers and students know they have five things in common, relationships and educational outcomes both improve.

    Gehlbach explained that the similarities he and his colleagues established were not based on personal information, but on shared preferences. Gehlbach explained: one of the biggest surprises in reading the similarity research was how little some of the similarities were that caused positive feelings towards others.

    Though Gehlbach's study has limitations, he is encouraged by the results and eager to explore the phenomenon further.

    The National Storytelling Youth Olympics is an event where thousands of kids from grades 6 to 12 compete against each other by telling stories. It is sponsored by the Master's Degree Program in Reading and Storytelling at East Tennessee State University. The sole purpose of this event is to promote and encourage both the art and science of storytelling among middle school and high school students. Although this event is competitive, its underlying intent and goal is to provide students across the nation with a reason to practice numerous noncompetitive skills.

    Those skills include skillful sportsmanship , responsible behavior, and an attitude of respect for others and the storytelling genre. The eventual goal of the National Storytelling Youth Olympics is to encourage every classroom in America to discover (or rediscover) the beauty of storytelling and story performance.

    The National Storytelling Youth Olympics takes place usually around the first weekend in March. Students from all over the country arrive by bus, plane, or automobile in Johnson City, Tennessee. They usually arrive on Thursday or Friday. Those that arrive on Thursday take advantage of their early arrival by telling stories at local schools. On Friday, an evening meal is prepared for all contestants, coaches, and parents. Games are played, stories are told, and lifetime friendships begin. Saturday is the day of the big event. A luncheon(午餐会) is held in the afternoon so contestants can familiarize themselves with the surroundings and do a sound check.

    The event is divided into three categories separated by grades. Contestants are judged not only by their storytelling performance, but also by the attitude and behavior they display during the entire weekend. A winner is picked from each of the three categories; however, there is an overall winner who is granted the name of Grand Torch Bearer. This person is selected not only by the judges, but also by the contestants. After the winners have been announced, the contestants retreat back to their hotel where a celebratory ice cream party is held; and believe it or not, they tell more stories! This is what the National Storytelling Youth Olympics is all about: developing a love for the art of storytelling.

    Being an astronaut sounds cool, doesn't it? In space, they get to do some pretty amazing things, like floating (漂浮) in zero gravity(重力).

    However, there are also plenty of things that astronauts can't do because of their weightless environment(环境), and that's very sad. What's worse, they can't even let their sadness show -because it's impossible to cry in zero gravity.

    Of course, astronauts can still produce tears. But crying is much more difficult in space, reported The Atlantic in January. Without gravity；tears don't flow downward out of the eyes like they do here on Earth. This means that when you cry in space, your tears have nowhere to go — they just stick to your eyes.

    In May 2011, astronaut Andrew Feustel experienced this during one of his spacewalks. "Tears," he said, "don't fall off your eye...They just kind of stay there."

    Besides making your vision(视觉) unclear, this can also cause physical pain. Back on Earth, tears are supposed to bring comfort to the eyes. But that's not the case in space. The space environment dries out astronauts' eyes, and when tears suddenly wet the eyes, it can cause pain rather than comfort. "My right eye is painful like crazy." Feustel told his teammate during the walk.

    Since gravity doesn't work in space, astronauts need some extra help to get rid of the tears. Feustel chose to rub his eyes against his helmet to wipe the tears away. Another choice is to just wait — "When the tears get big enough they simply break free of the eye and float around," astronaut Ron Parise told The Atlantic.

    There are lots of small things — things like crying — that we are so used to on Earth, we usually take them for granted, until they become a problem in a totally different environment, like space. There, astronauts can't talk to each other directly. They also can't eat or drink in normal ways. They can't even burp (打嗝), because there is no gravity to hold the food down in their stomach. If they do burp, they just end up throwing up (呕吐) everything in their stomach, according to the UK National Space Center.

    Thus, perhaps it's only space explorers who can honestly say, "Gravity, you're the best."

In Hollywood, few actors have experienced a career as diverse and prolific as Harrison Ford. From the fearless Indiana Jones to the charming Han Sol o and the world-weary Rick Deckard, Ford's portrayal（饰演） of iconic characters has left a permanent mark on cinema and pop culture. Yet, the irony lies in how many of his career-defining roles fell into this "late bloomer's" lap by chance.

Born in Chicago, Harrison was discouraged from pursuing a career on the silver screen early on, having failed to land any significant parts. Instead, he turned to professional carpentry（木工） as a means to keep his family fed.

But fate had other plans. While working as a carpenter in Hollywood, Ford crossed paths with numerous celebrity clients such as Joan Didion and, most notably, director George Lucas, who hired him to build cabinets for his office. Little did Ford know that this chance encounter would lead to his breakthrough role as the charming Han Solo in Star Wars. Lucas was impressed by Ford's presence and offered him the iconic role. In time, Ford rose to a star.

Ford's next lucky moment came when he tried out for the role of Indiana Jones in a massive project by Lucas and Steven Spielberg, Raiders of the Lost Ark. Spielberg initially wanted Ford for the role, but Lucas was hesitant as he had already worked with Ford on Star War and 1973'sAmerican Graffiti. Then the production team tried many other possibilities but without luck. Eventually, the role went to Ford, strengthening his status as a Hollywood legend.

The film series became a worldwide sensation, stimulating people's imagination and inspiring a generation of future archaeologists. Over 40 years and four films later, Ford found himself completing the series with the fifth and final installment. Eighty-one-year-old Harrison received a five-minute standing ovation（鼓掌） at the Cannes Film Festival Premiere and picked up an honorary Palmed' Or for his achievements.

Ford's commitment to his career is evident as he said, "I love the work! My luck has been to work with incredibly talented people, to find my way into this crowd of geniuses." Despite his legendary status in Hollywood, Ford's humility shines through.
