Dear young musicians,

    Thank you for agreeing to take part in our Music Day. The whole idea of the day is for music students around the area to meet other players and receive expert teaching from our guests, six professional players. In the evening,you will perform the pieces you have worked on during the day at a concert which your friends and family can attend

    After you have registered（注册) at the reception,go to the main hall. First,there will be a short performance by our professional musicians who are joining us for the day. After this you will go into your classes to practice on your own instruments for the evening concert. There will also be a chance to experiment with a different institiment from the one you normally play,and see if you enjoy playing something more unusual — we have several instruments to choose from!

    The first part of the day will finish at 5 pm,when parents can collect students. For those remaining in the hall until the evening concert at 7 pm,there will be DVDs for you to watch,although you should also bring something to do while you are waiting. A change ot clothes is required for the evening — black trousers or a skirt and white top — so unless you are going home at 5 pm,you will need to have this with you at the start of the day.

    If for whatever reason you cannot attend the evening concert, you must tell us as soon as possible, as we need to know numbers in order to prepare the stage. We look forward to seeing you at the Young People's Music Day.

    Today, many people use plants from other places to design their yards. Well, do they have any influence on animals living nearby? As we know, plants supply food for things like insects and plant-eating animals. In turn, birds and meat-eating animals feed on these insects and plant-eating animals. It is easy to see how important plants are.

    Although foreign plants may look beautiful, they can cause problems when there are too many of them. I live in Virginia, USA, and sometimes see a plant—commonly known as Kudzu—that seems to cover everything in the area, even climbing over whole trees and houses.

    Kudzu is an unbelievable plant since it grows very fast. It was first brought to the United States from south-east Asia around the 1870's as a crop that farmers could grow. However, Kudzu quickly came to be considered harmful throughout the southern United States.

    Since Kudzu grows fast in many different environments, it can completely cover areas of land quickly. The plant is also not eaten by any insects or birds in the United States so it can grow unchecked. Kudzu can cover trees, bushes, and even houses. It costs the United States 500 million dollars a year to just keep Kudzu from growing too fast. The plant is a perfect example of what scientists call an invasive (侵略性的) species, which grows more quickly than other native plants.

    All foreign plants have the possibility to spread quickly. Not only are they costly, but planting them in gardens actually takes away food from insects. If everyone filled their garden with plants native to where they live, many lovely butterflies and other native creatures would be attracted to their backyards! So, take a look out of your window — how does your garden grow?

    New research suggests that there are only four basic facial expressions of emotion. However, how these expressions are understood might depend on where you are from.

    Research by scientists from the University of Glasgow in the UK has challenged the traditional view of how the face expresses emotions. Many scientists had believed that there were six basic emotions that people from all cultures recognized. These were happiness, sadness, fear, anger, surprise and disgust(厌恶). However, the University of Glasgow's work now suggests that the human face only had four basic expressions of emotions. This is because some pairs of emotions are impossible to tell apart, especially when they are first shown on the face. Fear and surprise, both share wide-open eyes. The facial expressions for anger and disgust also look the same.

    So if our faces are only able to express four basic emotions, how do we communicate much more complex feelings? The study found that the way expressions are understood is different in different cultures. Lead researcher Rachael Jack was studying this because “facial expressions were considered to be universal”, she explained. However, while looking at how people from the East and West recognize different parts of the face, they found that although there are some common features across cultures, the six basic facial expressions of emotion are not recognized universally.

    “We said we don't know what a disgust face looks like in China, so the best way to go about that is to make all combinations of facial movements and show the Chinese people and ask them to choose the ones they think are disgust faces.” With the software they developed, they discovered that in the early stages of signaling emotion, fear and surprise, and anger and disgust, were often confused. Jack explained that this development of facial expressions is related to biology and social situations.

    What has caught people's interest is the cross-cultural aspect of the work. “This study shows which emotions we share, and which are different in different cultures,” Jack said. This finding could help us develop new communication technologies, for example ones that use video-calling programs like Skype. When you talk to someone in Japan in the future, a programme could “read” your facial expressions and then “translate” them for the Japanese person. The Japanese person would see the Japanese facial expression on their screen. In this way, people from different cultures could understand each other better.

Volunteer Opportunities Abroad

    For those looking to break into the competitive world of journalism (新闻工作), this is for you! You will be working at “The Village”, an English and Romanian language magazine. As a writer you will work on special tasks, reporting local events with guidance from the editor. You will be interviewing local people, writing reports, and taking photographs. You will also have the chance to live with a local host family to experience their culture.

    Volunteers joining our project (项目) in Cambodia will travel to the island of Koh Sdach. You will become part of this tiny island, learn to dive (潜水), and take part in valuable social projects.

    During your stay you will complete a course to learn to dive. After that you will take part in dives to clean up rubbish under the sea and collect information on rare fish. During the two weeks you may also have the chance to join in a village fun day where volunteers play games with the village children.

    On this project you will spend two weeks living with a host family and coaching soccer in friendly West Africa! You will spend your two weeks in Accra helping local children develop their soccer skills. You will develop their skills and confidence while having fun playing soccer at the same time.

Yellowstone Weather

    Yellowstone National Park is at high altitude. Most of the park is above 7,500 feet (2,275 meters).

    Yellowstone's weather is unpredictable. In summer, it may be warm and sunny with temperatures in the high 70s. At night in any given month, the temperature may drop close to freezing. So it is best to come prepared for cold evenings and mornings, especially if you are camping or hiking. When you leave your campsite, please leave it prepared for possible thundershowers and wind.

    A sunny warm day may become fiercely stormy with wind, rain, sleet and sometimes snow. Without enough clothing, and easy day hike or boat trip can turn into a battle for survival.

    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.
