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.

    Today we talk about a time when half the world is waking from the dark, cold winter months. Spring! We often describe “spring” as a time of rebirth, renewal and awakening. Many trees are blossoming and early flowers are pushing through the earth. Things are coming to life!

    But the word “spring” is not just a season. It is also a verb that means something going on or coming out quickly. When you put “spring” and “life” together, you will get “spring to life”. This expression means something suddenly becomes very active or perhaps seems more alive! You may “spring to life” after hearing that a distant friend will be visiting you. Or maybe your favorite soccer team finally “sprang to life” in the second half, played well and won the match.

    Now, besides being a season and a verb the noun “spring” refers to a metal coil (线圈) that is wound tightly. When the coil unwinds, it often jumps. So, we often say a person “has a spring in his step” if he is lively and active. He might even appear to jump, or bounce a little when he walks.

    There is another way we use “spring” as a description. In the case of a “spring chicken”, “spring” means young. However, “spring chicken” is also an informal, humorous way to refer to someone who isn't young at all. So, we use this expression in the negative form, as in “no spring chicken”. For example, let's say you know an 85-year-old man who decides to run a marathon, even though he has never exercised before. You could say, “That's amazing! After all, he's no spring chicken.”

    But be careful when using this expression. It could be a little disrespectful. Let's say your boss shows you a picture of his wife, and you say, “Wow, she's no spring chicken.” That response would be disrespectful and a bad career move.

    Among the most popular forms of dieting is the South Beach diet, developed by Arthur Agatston of Miami, Florida. Dr. Agatston developed the South Beach diet for his patients with heart problems to lose weight. Since weight matters a lot in keeping heart healthy and traditional low-fat diets were too difficult for them to stick to, Dr. Agatston decided to create a plan that could help his patients. At first, the diet was just for his patients. Soon, thanks to his patients' success, the diet became the buzz in Miami, and eventually, word spread across the nation.

    This diet focuses on a healthy balance between carbohydrates（碳水化合物）and fats. It is based on eating a combination of “good” carbohydrates and fats, while limiting those “bad” ones. It is divided into three different phases.

    The first phase lasts for two weeks and is the strictest of the three. During this phase, you are asked to restrict（限制）all carbohydrates (good and bad). You are allowed to eat all types of fish, cheeses, eggs, and nuts, and a large number of vegetables. Most dieters can expect to lose between 8 and 12 pounds during this phase.

    During Phase 2, you are allowed to reintroduce some of those carbohydrates that are not allowed before. You are encouraged to start eating carbohydrates that have a low glycemic index（升糖指数）. But you should keep in mind that the key is moderation（适度）. Most people continue to lose 1-2 pounds per week. You continue with this phase until you reach your target weight.

    Phase 3 is designed to help you keep your weight. During Phase 3, you can reintroduce some of the carbohydrates that have a higher glycemic index, although again, this should be in moderation. Phase 3 is meant to be a way of life.

    During my third year of university, I spent six months studying in Rio de Janeiro, Brazil. Many are worried about travelling to Rio but I promise, it is worth a visit. Now I want to share my top recommendations (推荐) for experiencing Rio less as a tourist but more like a native Brazilian.

    Pedra Bonita

    Rio is full of hiking routes, and some Brazilians love to spend an afternoon hiking. My favorite route of all has to be Pedra Bonita. Pedra Bonita involves a steep climb of about an hour through tall trees, and I admit it is difficult in Rio's heat, but you are rewarded at the top with a wonderful view of the city, standing high above the green landscape and blue sea below.

    Mureta da Urca

    One thing you are sure to find in Rio is an amazing sunset, but a lot of the best spots tend to be full of tourists. In my opinion, Mureta da Urca is the most relaxing place to watch the sun set over the silver sea, with the figure of Christ the Redeemer standing tall in the background.

    Pedra do Sal

    Pedra do Sal is a historical area in the city centre and on Monday nights it is brought to life by the sound of samba. Hundreds of people gather in the street, food and drink stalls are set up and it becomes a giant street party with everyone enjoying the happy sound of live samba!

    Picanha

    If there were one Brazilian food I could bring back to the UK, it would be picanha. It is the tastiest cut of steak I have ever tasted, served alongside rice and beans.

    It was many years ago. I was a young dad sitting on the couch reading a fairy tale to my little girl. She sat next to me with her head on my arm as I told the tale. When it came to the end I finished with those famous words: "And they lived happily ever after." As I looked over to her with her wavy(鬈曲的), brown hair and big, innocent eyes I could see the smile on her face and I never wanted it to end. Then it dawned on me that the ending of the book was what I wanted for her. I wanted her to "live happily ever after".

    Still, deep in my heart I knew that this couldn't always be so. I knew that there would be times when her heart was broken. I knew there would be times when she cried in grief and I couldn't comfort her. I knew there would be times when all she felt was fear, sadness, sorrow, and despair. As I stroked her hair and smiled at her I hoped that those times would be brief and that she would have joy in her life more often than not. Living happily ever after, though, seemed out of the question.

    It takes me a lot of years to realize that it is possible to live happily ever after. You just have to do it "one day at a time". Happiness you see isn't some reward that you get at the end of your journey. Happiness isn't something that depends on what life you own. Happiness is something you create in your life choice by choice and day by day.

    The truth is happiness comes when you love. Love is a gift from God. It is love that mends broken hearts. It is love that heals grief. It is love that gives us joy. Choose to "live happily ever after, one day at a time".

    A night at the movies is always a good idea. But when you leave the theater and realize you just dropped $45 on a ticket and some snacks, you'll wish you had been patient enough to wait until the movie came out on Netflix. The average movie ticket price in the United States in 2000 was $5.39; now, a ticket is over $9.

    The main reason that movie tickets have gotten so expensive is because of inflation(通货膨胀). It was actually more expensive to go to the movies in the 70s than it is now. A ticket in 1978 cost $2.34. If you plug that into an inflation calculator, the same ticket would cost you $9.46 today. According to the National Association of Theater Owners, the average cost for a ticket today is $9.11.

    Another reason you need to dip into your life savings to see a movie on the big screen is that theaters are competing with streaming services that produce their own films, such as Netflix, Hulu, and Amazon. And let's be honest, sitting at home on your couch or in your bed is more comfortable than sitting in a cold theater.

    Because of streaming technology, movie theaters have to do something to bring in customers. Attractions­including alcohol, reclining seats(躺椅), surround sound, and 3-D movies are all examples of that. And those upgrades come at a price, leading to more expensive tickets.

    "There's all that extra cost, and it's really important for theater owners and companies to make that experience as enjoyable as possible," Patrick Corcoran, vice president of the National Association of Theatre Owners told Marketplace. "Because you're offering a superb experience­audience expectations are for the latest and greatest technology. Audiences are willing to pay more for a particular experience."
