Weddings in the United States vary as much as the people do. There are church weddings with a great deal of fanfare(仪式上的短曲); there are weddings on mountain tops with guests barefooted; there have been weddings on the ocean floor with oxygen tanks for the guests. But many weddings, no matter where or how they are performed, include certain traditional customs.

    Before a couple is married, they become engaged. And then invitations are sent to those who live nearby, their close friends and their relatives who live far away. When everything is ready, then comes the most exciting moment.

    The wedding itself usually lasts between 30 and 40 minutes. The wedding party enters the church while the wedding march is played. The bride carrying a bouquet enters last with her father who will “give her away”. The groom enters the church from a side door. When the wedding party is gathered by the altar, the bride and groom exchange vows(誓言). It is traditional to use the words “to have and to hold from this day forward, for better, for worse, for richer, for poorer, in sickness and in health, to love and to cherish, till death do us part.” Following the vows, the couple exchange rings. Wearing the wedding rings on the fourth finger of the left hand is an old custom.

    After the ceremony, there is often a party, called a “reception” which gives the wedding guests an opportunity to congratulate the new couple.

    The car in which the couple leaves the church is decorated with balloons. The words “Just Married” are painted on the trunk or back window. And then the couple go in their honeymoon.

    Some time ago, I discovered a whole lot of antique(古董) shops near my home. So I left home one morning carrying the char that had a broken leg. I didn't think there would be any difficulty in getting it mended. I went into the first shop expecting a friendly reception. I was quite wrong. The man wouldn't even look at my chair.

    The second shop, although slightly more polite, was just the same, and the third and the fourth — so I thought that my approach must be wrong.

    I went into the fifth shop with a plan in my mind. I placed the chair on the floor and said to the shopkeeper, “Would you like to buy a chair?” He looked it over carefully and said, “Yes. How much do you want do it, sir?” “Twenty pounds,” I said. “Ok,” he said, “I'll give you twenty pounds.” “It has a slightly broken leg,” I said. “Yes, I saw that; it's nothing.”

    Everything was going according to the plan and I was getting excited. “What will you do with it?” I asked. “Oh, it will be easy to sell once the repair is done.” “I'll buy it,” I said. “What do you mean? You've just sold it to me.” he said. “Yes, I know but I've changed my mind. I'm sorry. I'll give you twenty-seven pounds for it.” “You must be crazy,” he said. Then, suddenly the penny dropped. “I know what you want. You want me to repair your chair.” “You're right.” I said. “And what would you have done if I had walked in and said, ‘Would you mend this chair for me?'” “I wouldn't have agreed to do it,” he said. “We don't do repairs, not enough in it and too much trouble. But I'll mend this for you, shall we say for five pounds?” He was a very nice man and was greatly amused by the whole thing.

    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.

    Love to sink into your chairs and relax when you get to school. Then you will not be happy to hear that schools all over the world are seriously considering exchanging traditional desks for ones with no seats at all — Yes, that means you will be encouraged to stand through those already too long math and science lessons! Why would anyone even think of putting kids to such cruelty. Experts say it improves their health and helps fight obesity. While that may seem a little far-fetched (牵强的), the officials at the few schools around the world seem to agree.

    Among them are educators from the College Station Independent School District in Texas, who recently completed a week-long experiment involving 480 students across three elementary schools. The 374 kids that agreed to participate in the study were provided a device that helped record step count and calorie consumption over the entire period.

    All 25 teachers involved in the study reported that students appeared to be more alert and concentrate better, when allowed to stand. The one thing that did surprise the researchers was that younger kids were more willing to stay standing than kids in higher grades. They believe this may have something to do with the fact that after years of being asked to “sit still”, older kids have a harder time adjusting to this unexpected freedom.

    American schools are not the only ones reporting success with stand-up desks. Four schools in Perth, Australia, which have been testing them since October 2013, have seen similar results. In May 2014, Grove House Primary School in West Yorkshire, became Europe's first test one, with a seven-week trial that involved the use of desks made by Ergotron in their fifth-grade classrooms. While official results are not out yet, early reactions from both teachers and students, have been extremely encouraging.

    The findings of these studies and others done previously, all seem to mean that allowing kids to move around in classrooms is a win-win for students and teachers — it helps kids get healthier and provides educators with a more attentive audience.

    Teenagers around the world can be happy with the news that the brain will ignore parents' order when they tap on their smartphones. A new scientific study from the University College London has shown that humans may temporarily go deaf when they're focusing on something visual at the same time.

    The researchers played the normal-volume sounds in the background. And 13 volunteers experienced inattentional deafness as their visual tasks became increasingly difficult. “We found that when volunteers were performing the demanding visual task, they were unable to hear sounds that they would normally hear,” Maria Chait said in a statement. “The brain scans showed that people didn't filter out the sounds on purpose. They were not actually hearing them in the first place.”

    The findings, published in the Journal of Neuroscience, suggest that the centre of sights and the center of sounds share limited resources. Inattentional deafness is a common everyday experience and the study explains why, according to UCL Institute of Cognitive Neuroscience Professor Nili Lavie.

    If you try to talk to someone focusing on a book, game, or television program and don't receive a response, they aren't necessarily ignoring you. They simply might not hear you at all. This could also explain why you might not hear your bus or train stop being announced if you're absorbed in your phone, book or newspaper. However, some loud sounds will still be able to break through.

    Some situations could become potentially dangerous when the quieter ones go unheard. As you can imagine, in the operating room, when a doctor concentrates on his work, he might not hear the equipment beeping. It also applies to drivers who concentrate on complex directions. Fortunately, experts have given us some useful tips on preventing such situations.
