Body language is one of the most powerful means of communication, often even more powerful than spoken language. It is said that our body movements communicate about 50 percent of what we really mean while words only express 7 percent. So, while your mouth is closed, your body is just saying.

    Arms. How you hold your arms shows how open and receptive you are to people you meet. If you keep your arms to the sides of your body or behind your back, this suggests you are not afraid of taking on whatever comes your way. Outgoing people generally use their arms with big movements, while quieter people keep them close to their bodies. If someone upsets you, just cross your arms to show you're unhappy!

    Head. When you want to appear confident, keep your head level. If you are a monitor in class, you can also take on this position when you want your words to be taken seriously. However, to be friendly in listening or speaking, you must move your head a little.

    Legs. Your legs tend to move around a lot more than normal when you are nervous or telling lies. If you are at interviews, try to keep them still!

    Posture (姿势). A good posture makes you feel better about yourself. If you are feeling down, you normally don't sit straight, with your shoulders inwards. This makes breathing more difficult, which can make you feel nervous or uncomfortable.

    Mouth. When you are thinking, you often purse(噘嘴) your lips. You might also use this position to hold back an angry comment you don't wish to show. However, it will probably still be noticed, and people will know you're not pleased.

    Face. When you lie, you might put on a false face. But that expression would crack briefly, allowing displays of true emotions such as happiness, sadness, disgust (厌恶) and fear to come through.

    Humans are social animals. They live in groups all over the world. As these groups of people live apart from other groups, over the years and centuries they develop their own habits and ideas, which are different from other cultures. One important particular side of every culture is how its people deal with time.

    Time is not very important in nonindustrial societies. The Nuer people of East Africa, for example, do not even have a word TIME that is in agreement with the abstract thing we call time. The daily lives of the people of such nonindustrial societies are likely to be patterned around their physical needs and natural events rather than around a time schedule(时间表)based on the clock. They cook and eat when they are hungry and sleep when the sun goes down. They plant crops during the growing seasons and harvest them when the crops are ripe. They measure time not by a clock or calendar(日历),but by saying that an event takes place before or after some other event Frequently such a society measures days in terms of "sleeps" or longer periods in terms of "moons." Some cultures, such as the Eskimos of Greenland measure seasons according to the migration of certain animals.

    Some cultures which do not have a written language or keep written records have developed interesting ways of "telling time". For example, when several Australian aborigines want to plan an event for a future time, one of them places a stone on a cliff or in a tree. Each day the angle of the sun changes slightly. In a few days, the rays of the sun strike the stone in a certain way. When this happens, the people see that the agreed-upon time has arrived and the event can take place.

    In contrast(成对比), exactly correct measurement of time is very important in modern, industrialized societies. This is because industrialized societies require the helpful efforts of many people in order to work. For a factory to work efficiently (well, quickly and without waste), for example, all of the workers must work at the same time. Therefore, they must know what time to start work in the morning and what time they may go home in the afternoon. Passengers must know the exact time that an airplane will arrive or depart. Students and teachers need to know when a class starts and ends. Stores must open on time in order to serve their customers. Complicated(复杂的)societies need clocks and calendars. Thus, we can see that if each person worked according to his or her own schedule, a complicated society could hardly work at all.

    Older women who walk a little over three kilometers each day might live longer than less active women of the same age, a new study suggests.

    Many Americans hoping to stay healthy set a daily goal of 10, 000 steps, or about eight kilometers. They often have this goal because they are wearing electronic devices which set that target, note researchers in the United States. Their findings appeared recently in the publication JAMA Internal Medicine.

    But it is not clear how much intensity(强度)or speed matter when counting the health benefits of every step, the researchers write. They add that 10,000 steps per day might not be the right goal for everyone.

    For the study, researchers observed 17,000 women, all in their early 70s. They asked the women to wear accelerometers for at least four days. Accelerometers are small devices that measure the number of steps and the intensity of movement. The researchers followed up with the women much later, around 4. 3 years later, on average. Since the beginning of the study, 504 women had died. Compared to women who took no more than 2, 718 steps daily, the women who took at least 4,363 steps per day were 41 percent less likely to die.

    "Even a modest amount of steps is associated with lower death rates," said I-Min Lee, the lead writer of a report on the study. "The rate of stepping did not matter in these older women: it was the number of steps that mattered.

    The study had a few limitations. For example, the researchers only measured women's movements once, at the start of the study period. It is possible that the women's behaviors changed over time. Still, the results are "good news for older adults who may have difficulty walking at faster paces, "said Keith Diaz, a researcher at Columbia University. He was not involved in the study.

    "Any walking is better than nothing," Diaz said by email. "With even small amounts of walking, your risk of death will be sharply reduced "For those who have difficulty walking, other research shows that any form of aerobic activity provides health benefits," he added. "Swimming, bicycling or any form of activity that is continuous in nature will provide health benefits.

    A company in San Francisco, California, has found a way to turn used plastic bottles into women's shoes.

    Every day, millions of Americans drink water and other liquids from plastic bottles. More than 60 million of them are thrown away each day. Many of the plastic bottles end up in landfills or are burned with other waste products.

    A San Francisco start-up company called Rothy's, however, turns this plastic waste into environmentally friendly shoes. Roth Martin is the company's co-founder. He explains how they turn plastic into soft material for women's feet. They take the plastic, clean it, and break it down into small pieces. Then they press them through a device that makes soft fibers. Those fibers are then combined together. This is done by a 3D machine. It is designed to reduce waste while making the shoes. The knitted stuff and the inner part of the shoe are then attached to the shoe's outer part, called the sole (鞋底). This outer sole is also made from environmentally friendly material: responsibly sourced no-carbon rubber.

    Rothy's shoes are sold online. They are flat shoes, with either a rounded or pointed toe. They come in different colors and designs. They cost either $ 125 or $ 145 per pair, depending on the design. After American actress Gwyneth Paltrow discovered them last year, the demand for the shoes grew. Martin says there is no shortage of material to fill that demand. "We're not going to run out of water bottles any time soon. So we have a limitless supply of material, and I think that is a good sign for our future." When the environmentally friendly shoes wear out, customers can return them at no cost to a company that uses the recycled materials to make other products.

    For now, the shoes are only available to be shipped in the United States. However, the company says it will add international shipping in the near future.

The journey to discover myself，care for myself and love myself has been a long one.But，it's been a journey that has finally saved my life.

I remember throwing up for the first time when I was 8 years old.Somehow I had developed the belief that being thin was the only way to be accepted and loved.This way of thinking intensified（加剧） as I got older and bulimia（神经性贪食）became more and more deeply rooted in my life.

When I was 15 years old my family said goodbye to everything we had ever known and boarded the plane for New Zealand.I felt alone and scared in a world that was completely different to anything I had ever known.Eating helped numb（麻木）my pain and throwing up helped keep me thin.

By the time I went to university I was throwing up over 15 times a day.I was so ashamed of what I had become.

Although my bulimia had completely turned my life upside down，I knew one thing for sure that I loved my family more than anything in the world.This belief eventually made me pick up the phone and book my first appointment with a therapist（治疗专家）.

The first session I had with my therapist，Amanda，was amazing.I walked out of her office feeling like I had finally done something positive for myself Amanda made me realize that I wasn't alone in my suffering and there were thousands upon thousands of girls just like me.

I met regularly with Amanda for the best part of a year，over which time I learnt how to treat myself kindly，respect myself and love myself.I said goodbye to bulimia after over a decade of suffering.

Just turn to face the direction of self﹣discovery，self﹣love and self﹣acceptance and keep walking until you get there.It will be the journey of a lifetime.
