One October morning, I got off the all-night train in Mandalay, a city in Myanmar. A rough man came up and offered to show me around. The price he asked was less than I would pay for a bar of chocolate at home. So I climbed into his trishaw(三轮车).

    As he was showing me around, he told me how he had come to the city from his village. He'd earned a degree in mathematics. His dream was to be a teacher. But of course, life is hard here, and so for now, this was the only way he could make a living. Many nights, he told me, he actually slept in his trishaw so he could catch the first visitors off the all-night train.

And very soon, we found that in certain ways, we had so much in common—we were both in our 20s, we were both fascinated by foreign cultures—-that he invited me home.

    So we turned off the wide, crowded streets, and came to rough, wild alleyways(小巷). I really lost my sense of where I was, and realized that I could easily get cheated or something even worse.

    Finally, he stopped and led me into a hut. And then he reached under his bed. Something in me froze. I waited to see what he would pull out. And finally he took out a box. Inside it was every single letter he had ever received from visitors from abroad.

    So when we said goodbye that night, I realized he had also shown me the secret point of travel, which is to go inwardly(向内心)as well as outwardly to places you would never go otherwise, to go into uncertainty, even fear.

    At home, its dangerously easy to think we're on top of things. Out in the world, you are reminded every moment that you're not, and you can't get to the bottom of things, either.

    Being the head of a high school for many years, I grew tired of budget meetings, funding cuts, and many other administrative chores. I started to dream of retirement. Sitting in traffic on a weekday morning, I would find my mind wandering. I would imagine spending time with my grandchildren, quiet evenings with my wife, traveling, or rediscovering some great books. I told myself that I wouldn't sign myself up for any committees, any classes, or anything requiring a schedule.

    My first day of retirement came at last! I cooked a great breakfast for my wife and me, leisurely read the paper, cleaned a bit of the house, and wrote a few letters to friends. On the second day, I cooked breakfast, read the paper … On the third day. This is retirement? I tried to tell myself that it was just the transition, that those golden moments were right round the corner, and that I would enjoy them soon enough. But something was missing.

    A former colleague asked a favor. A group of students was going to Jamaica to work with children in the poorest neighborhoods. Would I interrupt my newly found “happiness” and return to the students, just this once? One trip. That's all. My bags were packed and by the door.

    The trip was very inspiring. I was moved not only by the poverty I saw but also by the sense of responsibility of the young people on the trip. When I returned home, I offered to work one day a week with a local youth organization. The experience was so positive that I was soon volunteering nearly full-time, working with students across North America to assist them in their voluntary work.

    Now, it seems, the tables have turned. Some days I am the teacher, other days I am the student. These young people have reawakened my commitment to social justice issues by challenging me to learn more about the situation in the world today, where people are still poor and suffer because of greed, corruption and war. Most importantly, they have given me the opportunity to continue to participate in helping to find solutions. In return, I help them do their charitable projects overseas. I've gone from running one school to helping oversee the construction of schools in twenty-one countries!

    One night, Pilar was in a deep sleep when she was woken by her cat Inti. Inti was meowing wildly outside Pilar's bedroom and throwing himself against the closed bedroom door. When Pilar opened her eyes, she saw that her bedroom was filled with smoke. As she escaped her house with Inti in her arms, she saw that a fire was burning in her kitchen. Pilar could easily have lost her life, but Inti would not let that happen. Even though Inti could have escaped the house through a cat door, he wouldn't leave Pilar.

    As amazing as this story is, it is not as uncommon as you may think. Take the example of Charlotte Lee and her horse, Thunder. One summer night, the whole family was asleep with the windows open. It was normally very quiet where they lived. Suddenly, there was a loud noise. Charlotte woke up from her sweet dream, and the noise continued. Then she heard a horse running fast towards the house. The next thing she saw was Thunder standing outside her window, neighing(嘶叫) and shaking his head. She knew something was wrong. Charlotte quickly got everyone out of the house before the earthquake hit. Thunder has saved her life.

    There are also stories of wild animals coming to the rescue of humans. One animal known to be a friend of humans is the dolphin. Once, Todd Endris was surfing with his friends when he was attacked by a 13-foot(4-meter) shark. In the middle of the attack, a group of dolphins came to his rescue by forming a protective ring around Endris until he could get safely to shore. Without the help of the dolphins, there is little chance that Todd could have escaped.

    No one is sure why animals have so often come to our rescue. However, it is clear that humans and animals enjoy a close relationship. It is important that we care for them as much as we can.

    Visual language is a form of communication that uses visual elements (元素) as opposed to formal written language to convey meaning or an idea, Graphicacy, the ability to communicate visually, is considered as important as literacy and numeracy, the abilities to read and count. Some people are visual thinkers, using that part of the brain that is emotional and creative to process and give meaning to information. Visual communication can find expression in paintings, drawings, symbols, or simply lines and shapes arranged for a specific effect.

    Art is an example of visual language. A painting or sculpture can convey ideas or arouse specific kinds of emotional responses. It may also express ideas about historical events, abstract concepts, or simply be about the way certain shapes or forms "work" together or create a certain effect on the mind. Some researchers believe that different parts of the brain respond in unique ways to colors and shapes.

Pictograms (象形文字) and ideograms (表意文字) are types of visual language. Pictograms are pictures that are similar to what they represent. They are still used today to communicate information. Many people around the world are familiar with the pictograms indicating such things as airports, public facilities, and non-smoking areas indicated by a cigarette in a circle with a line across it. Ideograms are pictures that represent ideas and can often be understood without the aid of written language. Some scholars track modern alphabets to pictures Letters are actually ancient pictures, and words are a series of pictures. Modern alphabet letters are not only phonetic (语音的) symbols but are based on ancient religious images and symbols.

    Musivisual communication is also a part of visual language. The term refers to music created specifically to improve the visual experience of film. It corresponds to the images being seen on the screen, and the music may arouse a sense of terror, fear, or other emotions. Most movie goers understand the language of musical clues showing that something dramatic or important is about to happen.

    Being able to land safely is a critically important skill for all flying animals. Whereas terrestrial animals face no particular challenge when they need to stop running or crawling, flying animals move at much higher speeds, and they must be careful about how they land. Hitting the ground, or even water, at full flight speed would be quite dangerous. Before touching down, they must decrease their speed in order to land safely. Both bats and birds have mastered the skill of landing, but these two types of flyers go about it quite differently.

    In the past it was believed that, in terms of flying mechanics, there was little difference between bats and birds. This belief was based only on assumption, however, because for years nobody had actually studied in detail how bats move their wings. In recent years, though, researchers have discovered a number of interesting facts about bat flight. Bats are built differently from birds, and their wings incorporate(结合) both their front and hind limbs (后肢). This makes their limbs working together more difficult for bats and, as a result, they are not very good at flying over longer distances. However, a bat can quickly change its direction of flight or completely reverse it, something a bird cannot easily do.

    Another interesting characteristic of bat flight is the way in which bats land—upside down! Unlike birds, which touch down on the ground or on tree branches, bats can be observed flying around and then suddenly hanging upside down from an object overhead. How do they do it? A group of researchers recently used video cameras to film bats landing on nets suspended from the ceiling of their laboratory and studied the recordings in slow motion. They painted spots on the bats' wings to see in detail what happens to the wings in flight and during touchdown. It turns out that the bats flew in a straight line up to the net and then quickly flipped over and attached themselves to it upside down. One disadvantage to this landing routine is that the bats often slam into their landing spot with some force, which probably causes pain. However, not all bats hit their landing spots with the same speed and force; these will vary depending on the area where a bat species makes its home. For example, a cave bat, which regularly rests on a hard stone ceiling, is more careful about its landing preparation than a bat more accustomed to landing in leafy treetops.

    The University of Birmingham is the first excellent UK Russell Group university to announce that it will accept the "Gaokao" exam for high­flying Chinese students wishing to join its undergraduate courses in 2019. High school students who complete the "National Higher Education Entrance Examination", or Gaokao, with top grades will be able to apply for direct entry onto Birmingham degree programmes without first completing a foundation year which is a routine for the freshman.

    Gaokao is usually taken by students in their last year of senior high school and, every year, each province in China sets the grades required to gain admission to its universities. It is usually held across China in early June. Students are tested in Chinese, Mathematics, a Foreign Language and social sciences or natural sciences.

    University of Birmingham Vice­Chancellor Professor Sir David Eastwood said: "The University of Birmingham has been challenging and developing great minds for more than a century. We welcome people from around the globe to study at Birmingham and Chinese students form an integral part of our education and research community. We are further opening access to Birmigham's wealth of education opportunities for the brightest and most dedicated Chinese students by accepting this strict and important qualification. I look forward to welcoming these high­flying students to the University of Birmingham."

    Gaokao is increasingly accepted by universities in Australia, the USA, Canada and mainland Europe. Birmingham will only be considering high quality students who achieve a minimum 80% Gaokao score and meet additional academic and English language requirements.

    Professor J on Frampton, Director of the University of Birmingham's China Institute said: "The University of Birmingham has a long history of educating students from China and one of our most famous graduates is Li Siguang­the founding father of Chinese geology. I am delighted that the University is now accepting the Gaokao. This gives the brightest and best Chinese students an opportunity to move straight into the first year of our undergraduate programmes and experience the benefits of studying at a global Top 100 university, such as Birmingham."
