    There are two main types of non­verbal communication. Body language is the first. Body language is body movements that depend on a person's attitude or feelings. Body language includes the way people walk，how they stand，and their facial features. In other words，any kind of meaning is shown by a person's attitude or body movements. For example，when a boy is sad he may drop his head and walk slowly. Or，if a girl is happy，she might run and jump or stand up straight and put her hands in the air. People don't have to say anything to show how they feel about things. The colour of people's skin may even show how they feel. For example，if people with light coloured skin get embarrassed，their skin may turn red，or if they are worried，they might get pale. Body language can be voluntary(主动的) or involuntary(无意识的)．An interesting fact is that blind children will smile when happy even though they have never seen a smile.

    The next main type of non­verbal communication is gestures. Gestures are communications like facial expressions，hand signals，eye gazing，and body postures. Examples include smiles，handshakes，waving，and raising certain fingers to say something. For instance，if you saw a friend at a noisy carnival，you might smile and wave at your friend. You might also point at the Ferris wheel if you wanted to meet your friend there. You could do all of these things without saying a word. Another great example is in baseball when the catcher signals to the pitcher the kind of pitch to use for the batter that is up.

    “Image is everything.” An entire industry has been built upon the concept that image is everything, but an appealing image isn't enough when there's no substance behind it.

    First of all, one should consider how important image is in selling products and services. Advertising agencies have raised the art of creating an image to a state of near perfection. But if the product or service doesn't live up to it, customers will be very dissatisfied. The recent scandal (丑闻) about the Arthur Andersen accounting firm showed that behind that image, it had unfair business practices under the table. Despite the previous positive image, the firm is being accused of criminal actions. Although the image had been nearly perfect, the reality behind the image has led to its downfall.

    Similarly, personal consultants(顾问) can build up a very positive public image for politicians and movie stars in the view of the general commons. But once again, history is filled with examples of both that fell from grace (体面) like the story of the Hollywood actor giving in to the pressures of fame and fortune. With people, just as with products and services, image is certainly important, but without positive substance behind it, failure is close.

    To conclude, it's clear that an appealing image is extremely important to success, whether that image is related to selling a product or service or to the “selling” of a person. But image is only half of the equation(等式). What lies behind that image is every bit as important as the image itself — the person or product must live up to that image or there's little chance for long-term success.

    People eat different things in different parts of the world.

    In south China we eat rice every day. Sometimes we eat it two or three times a day, for breakfast, lunch and supper. We usually eat it with fish, meat and vegetable.

    The Japanese eat rice, too. They also eat a lot of fish. They sometimes eat raw（生的）fish. In Africa, maize（玉米）is the most important food. People there make maize into flour（面粉）.From this flour they make different kinds of bread and cakes.

    In western（西方的）countries such as Britain, Australia and the U.S.A, the most important food is bread or potatoes. People there usually make their bread from wheat flour. They cook the potatoes in different ways. In England the most popular food is fish and chips. Sometimes people cook this food at home, but usually they buy it at the shop. They eat this food at home, in their work place, in the park or on the road. People call it "take-away" food.

    China plans to launch 156 small satellites by 2025 to provide Internet services in low signal areas and places with adverse natural environment, according to China Aerospace Science and Industry Corporation (CASIC).

    Due to environmental conditions of deserts, mountains and seas, half of the world's population has no access to the Internet, and the information deficiency hampers local development.

    It will be China's first broadband Internet access system with small satellites hovering in low orbit, which will also help meet the needs of commercial space development.

    The project, named Hongyun, plans to send the first satellite by 2019, and launch four more by 2020. By the end of 2025, CASIC plans to have all of the 156 satellites in operation.

    The Hongyun Project, which focuses on communication, remote sensing and navigation, can offer communication and Internet services for China and less-developed 3 countries with reduced latency. Meanwhile, the project can also benefit emergency communication, sensor data collection and remote control of unmanned equipment.

    Currently, international maritime satellites are widely used in communications in mountainous areas and airplanes, but those satellites, 36, 000 kilometers above the Earth, have time and signal delay as well as high cost for providing services.

    The small satellites sent by the Hongyun Project will hover in low orbits only hundreds of kilometers to 1, 000 kilometers above the Earth, and thus could improve the Internet access. However, the low orbit satellites may face challenges in power supply, as they need more energy to reduce the influence of air-resistance compared to high orbit satellites. Experiments are needed to determine whether solar energy alone is enough.

    I remember the first time I got on a horse. When I was a little boy aged two, my mom agreed to let me take a short ride and that was it! From then on, I drove my parents crazy begging for a horse.

    When I was four, I had mutism, in which children stop speaking in certain social situations. I went days, weeks, months without a sound at school. At most, I might quietly whisper to a friend. I suffered silently through school until I was ten when a psychologist (心理学家) had an idea. He asked me what I wanted more than anything else in the world. He explained I was going to be given a chance to work for that. And I was permitted to whisper the answer in my mother's ear, "A horse."

    I was to get a pony, but I had to live up to my end of the bargain (讲价). I had a list of weekly tasks I had to finish. I had to answer the phone five times per week, something I had never done before. I had to say one word to my teacher at school and the list went on. For a child with mutism, saying one word to someone can be like climbing Mount Qomolangma. I did everything that was asked of me and the day came. His name was Sequoia, whom I fell in love with immediately. When I was in Sequoia's presence, I forgot all about my problems and felt strong and secure.

    I am a fully participating member of society these days. My horse and I made it through a master's degree. I may have made it otherwise, but I'm not sure. I feel I owe my life to the horse and I try to give it back to him. He has given me the best gift I could ever imagine, my life.
