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.

Model Railroading

    Would you like to know a fun way to learn about math? Well, you can do that with model railroading. Yes, it's true. You can learn about many school topics without using a school book. Besides that, there are many other benefits that model railroading brings us as well. In this article, we will discuss just a few of those benefits of model railroading.

Patience and problem solving skills

    When you build a model railroad, you have to plan your railroad out. You have to decide where the tracks (轨道) will go, where to put buildings, where to put streets and any other things you would like to add to your model railroad. Also, you have to think about any problems you may have with the design you choose. How will you make railroad crossings? How will you design hills, mountains, and rivers? Deciding on what to do with your model railroad takes a lot of thought and patience, but it is not as difficult as you may think.

Building skills

    With model railroading, you learn how to put together plastic models of buildings. Also, you can learn how to build a table for your design, or make scenery for the geography of your design. Your model railroad runs on electricity, so you learn about electronics as well. These are skills that not only help you build a model railroad; these skills will help you all throughout life.

Fun for family and friends

    Different from many video games, model railroading is a social hobby that lets you communicate with family and friends. This is because you have to communicate with family and friends as you build and run your model railroad. By spending time with the people in your life you love and care about, you learn to become closer and care more for each other. This is one of the best parts of model railroading as a hobby. Of course, the best part about model railroading is running the trains. Watching the trains run around the track and make all the sounds and do all the things that real trains do gives people hours of enjoyment. Also, there is great satisfaction in the fact that you, your family, and your friends built the model railroad.

    I hope you can learn to enjoy model railroading and experience all the benefits you just read about and many others. Happy railroading!

    The writer Margaret Mitchell is best known for writing Gone with the Wind, first published in 1936. Her book and the movie based on it, tell a story of love and survival during the American Civil War. Visitors to the Margaret Mitchell House in Atlanta, Georgia, can go where she lived when she started composing the story and learn more about her life.

    Our first stop at the Margaret Mitchell House is an exhibit area telling about the writer's life. She was born in Atlanta in 1900. She started writing stories when she was a child. She started working as a reporter for the Atlanta Journal newspaper in 1922. One photograph of Ms. Mitchell, called Peggy, shows her talking to a group of young college boys. She was only about one and a half meters tall. The young men tower over her, but she seems very happy and sure of herself. The tour guide explains: “Now in this picture Peggy is interviewing some boys from Georgia Tech, asking them such questions as 'Would you really marry a woman who works?'

    And today it'd be 'Would you marry one who doesn't?' ”

    The Margaret Mitchell House is a building that once contained several apartments. Now we enter the first floor apartment where Ms. Mitchell lived with her husband, John Marsh. They made fun of the small apartment by calling it “The Dump”.

    Around 1926, Margaret Mitchell had stopped working as a reporter and was at home healing after an injury. Her husband brought her books to read from the library. She read so many books that he bought her a typewriter and said it was time for her to write her own book. Our guide says Gone with the Wind became a huge success. Margaret Mitchell received the Pulitzer Prize for the book. In 1939 the film version was released. It won ten Academy Awards, including Best Picture.

    A rabbit and two ducks were good friends. They used to meet on the bank of a river and play together. One day the ducks told the rabbit that they had found a carrot farm on the other bank of the river. The rabbit was excited and quickly asked for the help of his friends to cross the river, reach the farm and enjoy the carrots. The ducks agreed to carry him across the river.

    They made a wonderful plan to cross the river. The two ducks entered the river and stayed close to each other. The rabbit carefully got on their backs and stayed still. Then the ducks slowly swam across the river, staying close to each other. The rabbit cautiously stayed on top of the moving birds.

    Right before they reached the center of the river, the ducks suddenly saw a large number of fishes swimming together. In the excitement of finding a delicious meal in the water, the ducks quickly swam to either side to catch the fishes. They forgot about the poor rabbit on their backs, who fell down into the deep river as the ducks moved away. The ducks remembered their job only after they finished their meal. However, by that time the poor rabbit had already drowned (淹死). The foolish ducks were sorry to miss their good friend.

    From this short story, we know love should not be just words and talk; it must be true love, which is shown it in action.

    From roller coasters to adventure tours performances to experiments, there are plenty of exciting attractions in the UK. Here is our pick of the best attractions that children can visit.

    China is showing the world its great resolve in the global climate campaign with concrete and self-motivated efforts as well as serious commitment.

    At the opening ceremony of the Paris climate summit, Chinese President Xi Jinping restated China's plan made in June to cut its carbon emissions(排放)per unit of GDP by 60-65 percent from 2005 levels by 2030, and increase non-fossil fuel sources in primary energy consumption to about 20 percent.

    With a large population, China is facing increasing resource limits, severe environmental pollution and a worsening ecosystem, and its citizens are also becoming increasingly aware of environmental problems. Suffering environmental problems and seeing the efforts as important to transforming its economic growth pattern, the country has much at risk if climate change is left unattended.

    Actually, climate change efforts are already included in China's medium-and long-term program of economic and social development, and ecological efforts are the clear characteristics in China's 13th Five-Year Plan(2016-2020).

    Although it is and will be a developing country for a long time to come, China has been actively involved in the global campaign against climate change, now topping the world in terms of energy conservation and use of new and renewable energies.

However, China's development rights need to be respected. It is unfair to overstress China's status as one of the world's largest greenhouse gas emitters and regard it as the major part of responsibilities in the global fight against climate change.

    It is worthy of notice that China's emissions of greenhouse gases per person are far lower than those of developed countries, especially the United States, although rapid economic expansion and its population base have made it one of the biggest producers of the gases.

    To show its great resolve, Beijing in September also announced the establishment of an independent South-South cooperation fund of 20 billion RMB to help developing countries affected by global warming.

    While China is eagerly accomplishing its policy commitments, developed countries should stop questioning China's commitment to fighting climate change and pointing fingers, and start shouldering their due responsibilities instead.
