Fort Scott High School English teacher Emily Rountree has been working this semester to raise money for Charity Water, a nonprofit organization that uses 100 percent public donations to help fund water projects in places without access to clean drinking water. Her goal was to motivate her students to use their writing in class to make a real-world difference. Twelve students got top grades for the project, and their articles will be published both in The Tribune and online. Here is one example:

    Did you know that there are many countries around the world that dont have access to safe drinking water? Just think: that could be you, or someone in your family. My name is Tanner Johnson, and I attend Fort Scott High School. In my English classes, we are trying to raise money for Charity Water. Charity Water is an organization that helps people get water in countries where there is no safe drinking water.

    In developing countries, 780 million people dont have access to clean drinking water. In Africa alone, people spend 40 billion hours every year just walking to get water. Women and children are the ones that mainly do the walking. They could be attacked or get hurt while they travel to get water. When they do get home, the water that they have brought is unsafe water from swamps, ponds, or rivers. If they had safe drinking water, they wouldnt have to worry about these problems, and they wouldnt be wasting hours of their day. Unsafe drinking water causes many different kinds of diseases that could lead to death.

    You could help save someones life, by donating $20 so we can help get them some safe drinking water. You can easily donate online at mycharitywater.org/fshsenglish, or you can send a check to Emily Rountree, payable to Fort Scott High School. If we dont help these people, then who will?

    Our lifestyles today are very busy. We have family, school, sports, entertainment and social activities to fit into a time that seems never enough. We need to be healthy to meet the demands of daily life. But what does it mean to have a healthy lifestyle?

To have a healthy lifestyle, we need to:

◆ eat different kinds of healthy food most of the time

◆ do exercise often

◆ have time to relax

◆ get enough sleep to give our bodies time to grow healthy and strong

    No matter which kind of lifestyle you agree on, just remember it's important to balance all aspects of life.

    Japanese researchers say they have developed a new type of glass that can heal itself from cracks and breaks. Glass made from a low weight polymer (聚合物) called “polyether-thioureas” can heal breaks when pressed together by hand without the need for high heat to melt the material.

    The research, published in Science, by researchers led by Professor Takuzo Aida from the University of Tokyo, promises healable glass that could potentially be used in phone screens and other fragile (易碎的) devices, which they say are an important challenge for sustainable (可持续的) societies.

    While self-healing rubber and plastics have already been developed, the researchers said that the new material was the first hard substance of its kind that can be healed at room temperature. The new polymer glass is “highly robust mechanically yet can readily be repaired by compression (压紧) at broken surfaces”.

The characteristics of the polyether-thioureas glass were discovered by accident by a graduate school student named Yu Yanagisawa, who was preparing the material as a glue. Yanagisawa found that when the surface of the polymer was cut, the edges would adhere to each other, healing to form a strong sheet after being manually compressed for 30 seconds at 21℃. Further experiments found that the healed material regained its original strength after a couple of hours.

    Yanagisawa told NHK that he didn't believe the results at first and repeated his experiments several times to confirm the finding. He said, “I hope the repairable glass becomes a new environment-friendly material that avoids the need to be thrown away if broken.”

    This is not the first time a polymer has been suggested as a healable screen for devices such as smartphones. Researchers at the University of California suggested the use of polymer that could stretch to 50 times its original size and heal breaks within 24 hours.

    Smartphone manufacturers have already used self-healing materials in devices. LG's G Flex 2 shipped in 2016 with a coating on its back was capable of healing minor scratches over time, although failed to completely repair heavier damage.

    According to the research conducted by repair firm iMend, over 21% of UK smartphone users were living with a broken screen, with smashed displays being one of the biggest issues alongside poor battery life.

    The Terracotta Army Museum is one of the must-visit attractions for all travelers to China. The attraction is located in Xi'an, in west China's Shanxi Province.

    What's special?

    The terracotta Army is the buried army of Qin Shi Huang, an ancient Chinese emperor. These ancient sculptures were built and buried over two thousand years ago near the city of Xi'an. They were discovered in 1974 by farmers digging a well looking for underground water. Over a thousand terracotta warriors and horses have been uncovered since then. Each warrior is made of clay (泥土). They are around two meters tall. The sculptures are so detailed that it is possible to guess the age, rank and personality of each one. None of the soldiers are the same.

    The best time to visit

    The Terracotta Army is an indoor attraction, which is not likely to be affected by weather, so it can be visited all year round.

    As the Terracotta Army Museum is one of the must-visit attractions in China, it is crowded most of the time. We advise our customers to avoid the following periods when the museum is particularly crowded:

    National Day holiday(October 1-7), when it is fully packed.

    Labour Day holiday(May 1-3)

    Weather in winter is dry, cold and the least comfortable, and it's also the worst season for air quality, but it's also low season.

    Travel style: private, group or independent?

    A private tour means a lot of flexibility and you will be well taken care of by a private guide and driver. The museum is crowded most of the time, but our guides know how to escape the crowds, and help our customers to enjoy more in the museum. See our 3-Day Terracotta Warriors Private Tour.

Going with a group you won't get lost, but i lacks flexibility and personal service.

    Travelling on your own you may meet a lot of trouble, such as wasting time on finding a taxi or public bus to the attraction, lining up for tickets, reading maps, making sense of Chinese signs, etc.

Dear World:

    My son starts school today. It's going to be strange and new to him for a while. And I wish you would sort of treat him gently.

    You see, up to now, he's been king of the house. He's been boss of the backyard. I have always been around to repair his wounds, and to ease his feelings.

    But now things are going to be different.

    This morning, he's going to walk down the front steps, wave his hand and start on his great adventure that will probably include wars and tragedy and sorrow.

    So, World, I wish you would sort of take him by his young hand and teach him the things he will have to know. Teach him but gently, if you can. Teach him the wonders of books. Give him quiet time to ponder(思考) the eternal mystery of birds in the sky, bees in the sun, and flowers on the green hill. Teach him it is far more honorable to fail than to cheat. Teach him to have faith in his own ideas, even if everyone else tells him they are wrong. Teach him to sell his physical strength and brains to the person who offers the most money, but never to put a price on his heart and soul. Teach him to close his ears to a criminal gang (团伙) ...and to stand and fight if he thinks he's right. Teach him gently, World, but don't coddle him, because only the test of fire makes fine steel.

A Mother

    For many years, machines have been doing work that people once did, including some difficult jobs. Search and rescue operations in dangerous environments are often seen as the first areas that will employ high technology robots. But there is another area where they may soon take jobs traditionally held by human beings: the restaurant industry.

    Teams from around the world competed in early June at the DARPA Robotic Challenge Finals in California. A team from R. O. Korea and its robot, called DRC-Hubo, won first place in the competition. The second and third place finishers were from the United States.

    The robots were required to drive a vehicle, climb up steps and do mechanical work. Such activities are easy for humans to perform, but more difficult for machines.

    Not all of the competitors were successful. The failures showed how difficult it is to design effective walking machines.

    Recently, crowds gathered for the food machinery and technology show in Tokyo, Japan. They witnessed a robotic chef preparing food. Other machines cooked, baked tasty pastries and even made sushi.

    Akihiro Suzuki works at Yaskawa Electric, a company that develops robots. He says robots cannot do everything a human can, but they are able to work without becoming tired.

    He says robots cannot taste food, change heating levels or seasonings to get the best flavor. But he says if a food can be easily prepared, a robot can repeat the same movement to reproduce the same meal.

    One Japanese woman who saw the robots working wanted to bring them home. Masayo Mori says she would like to have a husband who could work like a robot. Suzumo Machinery demonstrated its sushi maker robot. It performs the often difficult work of wrapping the popular Japanese food. Hiroshi Monden is an official with the company. He says people all over the world now eat sushi, but there are not enough skilled workers to prepare for it. He says his machine can help anyone make sushi.
