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.

    Although environmental problems have existed for centuries, some people still care little about our environment. Problems like ice melting, electronic waste are lighting up news programs and becoming part of an ongoing dialogue about the environment.

    As a teenager, what do you think all the problems mean for your future and for the future of the planet? For our October 2016 writing contest, we want you to really consider what you think about environmental problems.

Located at Europe's biggest water park, the Galaxy Erding in South Germany, the world's first VR water slide takes the exciting experience to a whole new level by offering thrill-seekers the choice of three attractive worlds — Space, Sky, or Snow. By simply wearing a headset, riders can slide through a magical alien world, follow beautiful butterflies around floating islands or put themselves in a white winter wonderland. To make the experience even more heart-stopping, the 160-meter-long ride that lasts about 35 seconds has two uphill tracks that provide a roller-coaster-like experience.

    While the tire slide, which has been successfully tested by almost 10,000 park goers since it opened in February 2018, is impressive, the technology behind it, developed by California startup Ballast is even more so. The specially-created waterproof headsets can be worn in water up to a few meters deep, without harming the delicate Samsung Galaxy S8 mobile devices that run the custom software for the VR experiences. The headsets also charge wirelessly (无线地), allowing park operators to swap out sets throughout the day.

    The biggest challenge the company faced, however, was providing a suitable VR experience for everyone. That's because unlike roller coasters, where the speed is fixed for all riders, water slide speeds vary depending on the weight of the person. To overcome the issue, Ballast fixed  smart sensors (传感器) in important areas along the slide to keep track of the rider's progress at  all times. The information, conveyed through the headset, allows the custom software to adjust his or her location within the virtual world accordingly, making for a smooth, seasickness free ride for all.

    Though Ballast is thrilled at Space Glider's success, the company has bigger ambitions. They want to create an experience where guests will be able to swim underwater surrounded by virtual dolphins, whales, and even sharks, without wearing the heavy headsets!

    The American Craftsman style is a type of design. It was popular from 1900 to the 1930s. It changed the style of building in the United States.

    The craftsman style originally began in Europe. The British Arts and Crafts style arose in the 1860s. The unique designs of this movement tried to offer dignity to the common person. Handmade items were preferred because they were thought better than items that were mass-produced. But this British style was still Victorian. It still only served the wealthiest clients.

    In 1897 a group of Boston architects brought these handcrafted styles to American. They planned a show of craft objects, which turned out to be a huge success. Here they realized the potential and established the Society of Arts and Crafts on June 28, 1897. Its slogan was "to develop and encourage higher standards in the handicrafts."

    The American style began as the Victorian Era was ending. It emphasized handmade work. Originality and simplicity were highly valued. Local materials and the quality of the handicraft were very important, these traits were meant to dignify the modest homes of the middle class.

    These simple designs used glass and wood that were produced locally. They were also very elegant. The metalwork was a reaction to Victorian Opulence. The increase of mass-produced housing items was rejected. The American Craftsman used clean lines. It also relied on sturdy structure. Natural materials were always used in these houses if possible.

    This style introduced many changes to the average American home. New designs were made for families without servants. This was a trait of the new middle class. The kitchen went from being a hidden room to a prominent one. Another development was the breakfast nook. This new area provided the family with a place to gather at any time of day.

    Also, inspirational to the Craftsman style were the Shaker and Mission designs. The American Craftsman style led to the Art Deco Movement of the 1930s.

    When the cathedral of Notre Dame de Paris (巴黎圣母院) was on fire, it seemed as if the nation had lost a piece of its soul. A similar tragedy took place in 19th century Russia. And the rebuilding effort of the Russians might offer some inspiration for the French.

    Standing in the heart of the Russian capital, with 60,000 square meters of floor space and 1,500 rooms, the Winter Palace was among the world's grandest building. On Dec. 17, 1837, a fire broke out at the Winter Palace. By the morning of Dec.19, only the structure's framework remained.

    For the czar (沙皇), the fire presented a political challenge. Fearing that Russia's enemies would cast the fire as a blow to the czarist orders, the czar's supporters quickly worked together to shape the description of the fire in Russia and abroad. They wanted the country to appear united. And they certainly didn't want despair to become the story.

    The first full account of the fire was written in French by the poet Petr Viazemskii. A Russian translation appeared two months later. That text and others painted a highly idealized picture of the response to the tragedy. The accounts noted that the czar forcefully directed the fire's containment. Soldiers were selfless to save the palace. The Russian people felt the loss just as deeply as the czar.

    To erase the shame of the fire, the czar set a nearly impossible goal: rebuild the palace within 15 months, and he ordered that rebuilt palace look exactly as it had before. Thousands of workers labored on the construction site. They made rapid progress. On Match 25, 1839, the czar celebrated the rebirth of the Winter Palace.

Outwardly identical to the old version, the new palace featured more iron and brick in its structures—and less wood. It was far less fire-prone than the original.

    Notre Dame hasn't experienced the same level of destruction as the Winter Palace, if the Russian phoenix of 1839 is any indication, there is hope that a renewed Notre Dame will once again grace the banks of the Seine.

Kids and science seem to be made for each other!

The basic science is a combination of thought and experiment called the scientific method. It's where you start with an idea, create a way to prove or disprove your idea, and show what you learned based on facts. Learning to follow this process helps you think logically (逻辑地) and carefully. These important thinking skills can be used in many areas of study. To give a child practice with these thinking skills is like giving vitamins (维生素) to a developing mind.

One of the greatest things we can teach our children is to love learning. Learning science is a great way to do so. Children are easy to be interested in science. Because much of science is hands-on, it attracts most children. Nothing makes a child sit up and take notice like the "WOW!" of a great science showing.

Science opens doors to many subjects at school. Building love for science can be helpful in other areas of study. For example, one cannot love science for very long without becoming good at its language-math! So science encourages children to study math. An interest in science is an interest in how things were once understood compared to how they are understood now. Thus studying science lends itself easily to studying history. And after you do an experiment, you need to write a lab report. Therefore, writing becomes an important part of science.

Science is the basic thing for much of our life. The science of farming shows how our food is produced; biomedical science keeps us healthy; even our beds these days are designed according to scientific facts. We almost eat, sleep and breathe with the help of science! When we prepare the next generation (一代) of voters, creators and policy makers, it is important to make sure they are not only comfortable but also good at science.
