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.

    Movies are a great means of entertainment for many. There are some advantages of watching movies. Comedies, for example, help reduce your blood pressure. Laughter for 15 minutes during a film makes your blood vessels (血管) wider. Besides, when you watch a sad movie, you're more likely to come away from it thinking about loved ones and feeling happy about what you have.

    Watching movies can make you creative. A study shows that young children, who watched the use of magic in Harry Potter, score significantly higher in a creative thinking test than children who watched something else. Moreover, movies are very useful for strengthening people's mental health. They enable people to take time to really relax and temporarily forget about their daily concerns and problems.

    However, watching movies aren't always beneficial. Studies have shown that some people get real pleasure out of being scared by horror movies, but in various ways they may be risking their physical and mental health without even knowing it. When you watch a tense scene in a movie, your heart rate and blood pressure increase. Meanwhile this change in your brain chemistry reminds you of times when you were in a similar state, even if you have no idea you even had those memories. So if something horrible happens to you, being scared again by a movie can unintentionally make you experience it once more.

    Scientists, politicians and parents have debated for decades if being exposed to movie violence leads to actual real-life violence. Overall the answer to that is probably still up in the air, but a new study seems to prove that watching aggression on screen can contribute to being a bully (土霸) in real life, even if it is just in the short term.

    In conclusion, certain movies play a positive role, but not all movies do. It depends completely on the subject of the movie. So it's always advisable to choose the movies concerning something positive.

    “Why do I live? Why do I wish for anything, or do anything? Is there anything in my life that will not be destroyed by my death?”

    These are the words of the famous Russian writer Leo Tolstoy. Like Tolstoy, many people ask these difficult questions. And they struggle to find meaning in their life. Tolstoy spent his whole life trying to answer difficult questions like these. His search for answers influenced his writing.

    On August 28th, 1828, Leo Tolstoy was born in the country of Russia.

    As a child, Tolstoy was a member of the Russian Catholic Church. But as a young man, he began to question that faith. Tolstoy wanted to make his own moral decisions; he was tired of being told what to believe. He thought people could achieve a degree of perfection if they tried hard enough. So he worked very hard at being the best in everything he did. He thought that he would find meaning and truth in success.

    In the 1850s, Leo Tolstoy wrote his first stories. He wrote about his experiences in the army He also told stories about when he was a child. These works were published and Tolstoy became a well-known writer.

    Tolstoy was finally successful. He earned the respect he always wanted. Many wealthy and intelligent men met and talked with Tolstoy. Some of the men were writers like him. They talked a lot about faith and the meaning of life. But soon Tolstoy recognized that these men were not perfect. Now he knew they could not answer his questions about faith.

    So in the 1860s, Tolstoy tried a different way to find meaning. He opened a school for the children of his serfs -the people who worked on his land. These workers were very poor. He wanted to help them because he thought they were more honest than the wealthy people he knew.

    Tolstoy learned many things from his workers. He respected how they worked hard to provide for their families. He began to believe that marriage and family would give his life meaning. So in 1862, Leo Tolstoy married a young woman named Sonya Behrs.

    The next 15 years were the best years of Tolstoy's life. It was during this time that he wrote his most famous books -War and Peace and Anna Karenina. Many literature experts say that War and Peace is one of the greatest books ever written.

    Both War and Peace and Anna Karenina communicate Tolstoy's beliefs about the Russian nation, church and people. They also communicate what he thought was the answer to all his questions. Tolstoy believed humans were supposed to live a simple lite and take care of their families. Tolstoy thought this would satisfy him and bring him happiness.

    Leo Tolstoy is still a very respected writer today. His faith and writings have influenced many people. Tolstoy's search for the meaning of life is something everyone can understand. His teachings still interest people all over the world.

    When the telephone rings late at night, most women guess it must be one of only four or five people calling. A sister? Maybe. An emergency? Possibly. A mother? Probably not at that time of night. Much more probably it is a close female friend calling to tell you that she has split up with her boyfriend again or perhaps simply that a good movie has just started on TV.

    At a time when families are spread far and wide and marriages often end in divorce, friendships are becoming more and more important. Erika, a 32-year-old lawyer, is strengthened by her ten-year friendship with her married friend Jane. “I was very sick one night, so I called Jane at about 3:00 a.m. to talk about it,” she says. “She was very supportive and even came over to take me to the doctor's the next morning.”

    As American TV shows like Friends, which follows the lives of a very close group of young friends, have become more popular, many of us are beginning to see the value of such friendships. TV shows like this tell us that our romantic relationships may not last, but we need to keep in touch with our close friends if we want to survive.

A TV show called Real Women is about the lives and relationships of five former school friends. In this show, family, husbands, and work are all less important than friendships. One of its actresses says the show reflects her own experience. “Friendship is about commitment. I don't see some of my friends for ages but when we get together, it is as if time hasn't passed.”

    This is true of Erika and Jane's friendship. With Erika's family 200 miles away, it is Jane who keeps a spare set of keys to Erika's apartment and waters her plants whenever she is away. “Having Jane around gives me a certain amount of freedom. It is not the kind of thing that you could ask anyone to do, but she knows I would do the same for her.” Erika feels that because she no longer sees her family every day, she now enjoys a closer relationship with her best friend. Jane, who may move to a different city soon, is worried about leaving such a support system of friends. “My friends have more to do with my life than my parents and, therefore, I don't have to spend a lot of time explaining things to them. Friends are more up to date with what is happening.”

    Father's Day is celebrated today in 75 countries around the world. In my personal world, it's a day I like to think of my father's father.

    I learned a lot in my later life from my dad. But I learned something else, as a kid not even yet in school, from my grandfather. I learned to be curious. Little things fathers and grandfathers do can change the life of a child forever. In my case, this change came from necessity: My mom needed someone to look after little Allen, barely 4 years old, during the school day. My grandmother volunteered, and my grandfather came up with a way I could be watched while he worked in his clockmaker's shop.

    He seated me on a chair every day while I was there, right in front of his big workbench. He told me stories. He had a great sense of humor and a funny way of making a "buh-buh-buh" sound when he sensed my attention was weakening, and he encouraged me to ask questions about anything he was doing.

    Naturally, I was usually asking questions about clocks--what made the hands move, what the pendulum(钟摆) did, why you had to stop winding just before the weight hit the stop. Sometimes I just asked about which shiny parts went where.

    Most of all, he showed me how clocks worked. He treated me as if I were a sort of small grown-up. He never talked down to me, never told me I was "too young to understand".

    And so my grandfather granted me two things: A love of clocks, and an everlasting curiosity.

    As a journalist, I turned that fascination into explanations of why computers and software do what they do——and, perhaps even more importantly, why they fail at that task. I haven't been afraid of opening up the innards and looking for what is wrong with the computer.
