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 aweek-long experiment involving 480 students across three elementary schools. The 374 kids that agreed to participate in the study were provided with adevice that helped record step count and calorie consumption over the entireperiod.

    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 ofbeing 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 Catholic schools in Perth,Australia, which have been testing them since October 2013, have seen similar results. In May 2014, Grove House Primary School in Bradford, West Yorkshire,became Europe's first test one, with a seven-week trial that involved the useof 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 othersdone 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 engaged audience.

    A new collection of photos brings an unsuccessful Antarctic voyage back to life.

Frank Hurley's pictures would be outstanding—undoubtedly first-rate photo journalism—if they had been made last week. In fact, they were shot from 1914 through 1916, most of them after a disastrous shipwreck(海难), by a cameraman who had no reasonable expectation of survival. Many of the images were stored in an ice chest, under freezing water, in the damaged wooden ship.

    The ship was the Endurance, a small, tight, Norwegian-built three-master that was intended to take Sir Ernest Shackleton and a small crew of seamen and scientists, 27 men in all, to the southernmost shore of Antarctica's Weddell Sea. From that point Shackleton wanted to force a passage by dog sled(雪橇) across the continent. The journey was intended to achieve more than what Captain Robert Falcon Scott had done. Captain Scott had reached the South Pole early in 1912 but had died with his four companions on the march back.

    As writer Caroline Alexander makes clear in her forceful and well-researched story The Endurance, adventuring was even then a thoroughly commercial effort. Scott's last journey, completed as he lay in a tent dying of cold and hunger, caught the world's imagination, and a film made in his honor drew crowds. Shackleton, a onetime British merchant-navy officer who had got to within 100 miles of the South Pole in 1908, started a business before his 1914 voyage to make money from movie and still photography. Frank Hurley, a confident and gifted Australian photographer who knew the Antarctic, was hired to make the images, most of which have never before been published.

    Larry was on another of his underwater expeditions(探险)but this time, it was different. He decided to take his daughter along with him. She was only ten years old. This would be her first trip with her father on what he had always been famous for.

    Larry first began diving when he was his daughter's age. Similarly, his father had taken him along on one of his expeditions. Since then, he had never looked back. Larry started out by renting diving suits from the small diving shop just along the shore. He had hated them. They were either too big or too small. Then, there was the instructor. He gave him a short lesson before allowing him into the water with his father. He had made an exception. Larry would never have been able to go down without at least five hours of theory and another similar number of hours on practical lessons with a guide. Children his age were not even allowed to dive.

    After the first expedition, Larry's later diving adventures only got better and better. There was never a dull moment. In his black and blue suit and with an oxygen tank fastened on his back, Larry dived from boats into the middle of the ocean. Dangerous areas did not prevent him from continuing his search. Sometimes, he was limited to a cage underwater but that did not bother him. At least, he was still able to take photographs of the underwater creatures.

    Larry's first expedition without his father was in the Cayman Islands. There were numerous diving spots in the area and Larry was determined to visit all of them. Fortunately for him, a man offered to take him around the different Spots for free. Larry didn't even know what the time was, how many spots he dived into or how many photographs he had taken. The diving spots afforded such a wide array of fish and sea creatures that Larry saw more than thirty varieties of creatures.

    Larry looked at his daughter. She looked as excited as he had been when he was her age. He hoped she would be able to continue the family tradition. Already, she looked like she was much braver than had been then. This was the key to a successful underwater expedition.

    Elizabeth Blackwell was born in England in 1821, and moved to New York City when she was ten years old. One day she decided that she wanted to become a doctor. Thai was nearly impossible for n woman in the middle of the nineteenth century. After writing many tellers asking for admission (录取) to medical schools, she was finally accepted by a doctor in Philadelphia. She was so determined that she taught school and gave music lessons to get money for the cost of schooling.

    In 1849, after graduation from medical school. She decided to further her education in Paris. She wanted to be a surgeon (外科医生), but a serious eye problem forced her to give up the idea.

    Upon returning to the United States, she found it difficult to start her own practice because she was a woman. By 1857 Elizabeth and her sister, also n doctor, along with another woman doctor, managed to open a new hospital, the first for women and children. Besides being the first woman physician and founding her own hospital, she also set up the first medical school for women.

    Despite an advertisement campaign suggesting wall-to-wall special effects, “Bridge of Terabithia” is grounded in reality far more than in fantasy. Adapting Katherine Paterson's award-winning novel, the screenwriters David Paterson and Jeff Stockwell have produced a thoughtful and extremely affecting story of a transformative friendship between two unusually gifted children. The result is a movie whose emotional depth could appeal more to adults than to their children.

    Jess Aarons (Josh Hutcherson) is a sixth grader with four sisters, financially tensed parents and a talent for drawing. An introverted(内向的) kid who is regularly picked on by the school buses, Jess forms a bond with a new student named Leslie (Anna Sophia Robb), a free spirit whose parents, both writers, are fondly neglectful. An attraction between outsiders, their friendship feeds on her words and his pictures; together they create an imaginary kingdom in the woods behind their homes, a world they can control and where their minds can wander free.

    Beautifully capturing a time when a bully in school can occur as large as a monster in a nightmare and the encouragement of a teacher can alter the course of a life, “Bridge to Terabithia” keeps the fantasy in the background to find magic in the everyday. Gabor Csupo directs this, his first feature, like someone close to the pain of being different, fascinated in tiny, perfect details.

    With strong performances from all the leads, “Bridge to Terabithia” is able to handle adult topics with sensitivity. As the emotional landscape darkens, those who haven't read the book may be surprised at the sorrow the filmmakers cause without ever resorting to horror or terror. In other words, your children may cry, but they won't be traumatized so badly.

    Consistently smart and delicate as a spider web, “Bridge to Terabithia” is the kind of children's movie rarely seen nowadays. At a time when many public schools are being forced to cut music and art from the curriculum, the story's insistence on the healing power of a cultivated imagination is both welcome and essential.
