This is not a diet. It's a simple way to lose weight. You don't have to give up the food you love or join a gym. You just follow some habits thin people have. Keep them, and you'll become thin.

    Wake-up When you wake up in the morning, sit up slowly without using your hands. With legs straight out, lean forward(前俯) until you feel sore(酸痛的) in your back. It will use up 10 calories.

    Start with soup Order a clear soup, and have it before the main food. In this way, you'll feel fuller, so you'll eat less when the main food comes.

    An apple or more a day Apples are full of fiber(纤维) and water, so your stomach will want less. Studies show that people who eat at least three apples or pears a day may lose weight.

    Talk it up Every time you use the cell phone, stand up and walk around. Heavy people sit on average two and a half hours more each day than thin people. This skill is very important as standing up and walking around will burn up 50 or more calories.

    Use these skills, and you will have a big weight loss.

Life in the Clear

    Transparent animals let light pass through their bodies the same way light passes through a window. These animals typically live between the surface of the ocean and a depth of about 3,300 feet — as far as most light can reach. Most of them are extremely delicate and can be damaged by a simple touch. Sonke Johnsen, a scientist in biology, says, "These animals live through their life alone. They never touch anything unless they're eating it, or unless something is eating them."

    And they are as clear as glass. How does an animal become see­through? It's trickier than you might think.

    The objects around you are visible because they interact with light.  Light typically travels in a straight line. But some materials slow and scatter (散射) light, bouncing it away from its original path. Others absorb light, stopping it dead in its tracks.  Both scattering and absorption make an object look different from other objects around it, so you can see it easily.

    But a transparent object doesn't absorb or scatter light, at least not very much. Light can pass through it without bending or stopping. That means a transparent object doesn't look very different from the surrounding air or water. You don't see it — you see the things behind it.

    To become transparent, an animal needs to keep its body from absorbing or scattering light. Living materials can stop light because they contain pigments (色素) that absorb specific colors of light. But a transparent animal doesn't have pigments, so its tissues won't absorb light. According to Johnsen, avoiding absorption is actually easy. The real challenge is preventing light from scattering.

    Animals are built of many different materials — skin, fat, and more — and light moves through each at a different speed. Every time light moves into a material with a new speed, it bends and scatters. Transparent animals use different tricks to fight scattering. Some animals are simply very small or extremely flat.  Without much tissue to scatter light, it is easier to be see­through. Others build a large, clear mass of non­living jelly­lie (果冻状的) material and spread themselves over it.

    Larger transparent animals have the biggest challenge, because they have to make all the different tissues in their bodies slow down light exactly as much as water does. They need to look uniform. But how they're doing it is still unknown. One thing is clear for these larger animals, staying transparent is an active process.  When they die, they turn a non­transparent milky white.

    Alice Moore is a teenager entrepreneur (创业者), who in May 2015 set up her business AilieCandy. By the time she was 13, her company was worth millions of dollars with the invention of a super-sweet treat that could save kids' teeth, instead of destroying them.

    It all began when Moore visited a bank with her dad. On the outing, she was offered a candy bar. However, her dad reminded her that sugary treats were bad for her teeth. But Moore was sick of missing out on candies. So she desired to get round the warning, "Why can't I make a healthy candy that's good for my teeth so that my parents can't say no to it?" With that in mind, Moore asked her dad if she could start her own candy company. He recommended that she do some research and talk to dentists about what a healthier candy would contain.

    With her dad's permission, she spent the next two years researching online and conducting trials to get a recipe that was both tasty and tooth-friendly. She also approached dentists to learn more about teeth cleaning. Consequently, she succeeded in making a kind of candy only using natural sweeteners, which can reduce oral bacteria.

    Moore then used her savings to get her business of the ground. Afterwards, she and her father secured their first business meeting with a supermarket owner, who finally agreed to sell Moore's product-Cancandy.

    As CanCandy's success grows, so does Moore's credibility as a young entrepreneur. Moore is enthusiastic about the candy she created, and she's also positive about what the future might bring. She hopes that every kid can have a clean mouth and a broad smile.

    Meanwhile, with her parents' help, Moore is generally able to live a normal teenage life. Although she founded her company early on in life, she wasn't driven primarily by profit. Moore wants to use her unique talent to help others find their smiles. She donates 10% of AilicCandy's profits to Big Smiles. With her talent and determination, it appears that the sky could be the limit for Alice Moore.

    They were a happy family: four daughters all in the same school in different grades. The youngest, Janice, who was in my class, seemed to be glued (粘) to her mother's skirts. The three older girls took the bus to school every morning, but Janice was always driven to school by her mother.

    One Friday, Janice's mother asked for a talk with me. She said in a soft voice, "My husband is going to Europe on business for two weeks, and he insists that I go with him. I have tried to explain over and over that Janice needs me here. But he thinks that she will be fine without me so I have no choice; I have to go. I have told the babysitter to drive her every morning. Will you please give Janice special attention and help her? I want to be sure everything goes well for her."

    I told her that we would make every effort to support Janice. I even volunteered to meet Janice at her car so she would see a familiar face. As a mother myself, I'd like to help. Janice's mother thanked me for our understanding.

    On Monday morning, expecting a tearful, anxious child, I planned a special program of fun and games. I waited outside to greet Janice, but just then the bus arrived and not three, but four girls got off. Janice skipped along joyfully, saying "goodbye" to her sisters as she ran with two friends into the classroom. I walked slowly into the classroom and called Janice over to ask how the bus ride went. Impatiently she said, "Oh, I always want to take the bus with the other kids, but Mother needs to be with me. You see there won't be any more babies, so I have to be a baby a little longer. While she is away, I'll just ride the bus every day. I am five, you know."

    Laughter is a kind of universal body language that is shared by people of all nationalities, skin colors, cultures and traditions. But did you know that the ability to tell real laughter apart from fake (假的) laughter also varies among cultures?

    Greg Bryant, a professor of communication at the University of California, published a study in late July. In the study, 884 people from 21 countries were asked to listen to random recordings of laughter. Some of the recordings were made up of laughs from the bottom of the heart, while others were made by people who were asked to laugh on command.

    The study showed that people around the world have the ability to pick out real laughter, although their abilities vary from country to country. Residents of the Samoan Islands, were particularly good at it, correctly identifying real laughter 56 percent of the time. According to Bryant, people from smaller, less industrialized nations “are more accurate in identifying a natural smile” because they rely heavily on emotional engagement in order to predict others' behavior and create stronger social relationships.

    But how do people from different cultures detect natural laughter so easily? And what characters does real laughter have? As Professor Jessica Wolf of the University of California told the Association for Psychological Science, in real laughter, we produce qualities, such as higher pitch (音调) and volume, as well as faster bursts of no clear sounds.

    By contrast, fake laughter will "sound like speech". According to Science Daily, fake laughter is controlled by the same brain system that controls the lips and tongue. Bryant further explained that this system has active ability, saying "with this speech system, you can make a lot of different noises, including crying, laughter or scream. That's where fake laughter comes from".

    So that? s something to think about: next time one of your friends laughs at something you say, will you be able to tell if it's real or fake?

    When I was about 12 years old, my older brother, James, smuggled a BB gun into the house. Our parents had told us many times that we were not allowed to bring home guns or knives, even if they were just toys. Having any form of weaponry in our home was strictly forbidden.

    James brought me to his room. He opened his closet door and took out a shoebox that was buried beneath a heap of clothes. The BB gun was inside. I was immediately enamored by the shiny barrel.

    "Can I shoot it, Jamesie?" I asked, hopefully.

    "Noway,"James said, taking it from me and putting it back.

    One day, when no one was home, I went into James' closet and took it out. For some in explicable reason - I have no idea what I was thinking - I went to the front window of the second floor in our row house. I cracked the window open. I pointed the gun outside and shot. I quickly shut the window and peeked outside.

    In a matter of seconds, old Mr. Schlosberg came out of his grocery store. He looked back at his store window. He looked up the street. He looked down the street. Then he looked straight across to our house.

    Thankfully, Jamesie made it home before Mother or Father.

    As he stepped through the door, I could hear old Mr. Schlosberg call his name. "James, James," he called. "Come here, son."

    After several minutes, James ran back across the street and into the living room. I had retreated into the kitchen. "Alma!" he screamed. "Get out here! You cracked Mr. Schlosberg's window with my BB gun!"

    "Oh, please, Jamesie," I begged. "Don't let him tell Mother. She will whip my bottom real good!" Jamesie sighed. He wiped my tears and went back across the street to Mr. Schlosberg's. I don't know what James said to that man, but there was never a mention of the incident again.

    Years later, I found out Jamesie had used the money he got from his newspaper route to pay for Mr. Schlosberg's cracked window. He only got one cent for every paper he delivered. He managed to pay back the debt just before he went off to fight in World War II.

    Since that day, I have never touched a gun: a BB gun, a water gun, a real gun, or any other type.
