Seventy years ago, a group of well-known people from the art world headed by an Austrian conductor decided to hold an international festival of music, dance and theater in Edinburgh. The idea was to reunite Europe after the Second World War.

    It quickly attracted famous names such as Alec Guinness, Richard Burton, Dame Margot Fonteyn and Marlene Dietrich as well as the big symphony orchestras (交响乐团). It became a fixed event every August and now attracts 400,000 people yearly.

    At the same time, the “Fringe” appeared as a challenge to the official festival. Eight theater groups turned up uninvited in 1947, in the belief that everyone should have the right to perform, and they did so in a public house disused for years.

    Soon, groups of students firstly from Edinburgh University, and later from the universities of Oxford and Cambridge, Durham and Birmingham were making the journey to the Scottish capital each summer to perform theater by little-known writers of plays in small church halls to the people of Edinburgh.

    Today the “Fringe”, once less recognized, has far outgrown the festival with around 1,500 performances of theater, music and dance on every one of the 21 days it lasts. And yet as early as 1959, with only 19 theater groups performing, some said it was getting too big.

    A paid administrator was first employed only in 1971, and today there are eight administrators working all year round and the number rises to 150 during August itself. In 2004 there were 200 places housing 1,695 shows by over 600 different groups from 50 different countries. More than 1.25 million tickets were sold.

    Now many young people are traveling around the world on their own, not because they have no one to travel with, but because they prefer to go alone.

    Kristina Wegscheider from California first traveled alone when she was at college and believes that it is something everyone should do at least once in their life. “It opens up your mind to new things and pushes you out of your comfort zone.” Wegscheider has visited 46 countries covering all seven continents.

    In foreign countries, with no one to help you read a map, look after you if you get ill, or lend you money if your wallet is stolen, it is challenging. This is what drives young people to travel alone. It is seen as character building and a chance to prove that they can make it on their own.

    Chris Richardson decided to leave his sales job in Australia to go traveling last year. He set up a website, The Aussie Nomad, to document his adventures. He says he wished he had traveled alone earlier. “The people you meet, the places you visit, or the things you do, everything is up to you and it forces you to grow as a person,” said the 30-year-old man.

    Richardson describes traveling alone like “a shot in the arm”, which “makes you a more confident person that is ready to deal with anything”. He said, “The feeling of having overcome something on my own is a major part of what drives me each day when I'm dealing with a difficult task. I walk around with my head up because I know deep down inside that nothing is impossible if you try.”

    The great 19^thcentury explorer John Muir once said, “Only by going alone in silence can one truly get into the heart of the wilderness.”

    Edward Hibberd Johnson was an American inventor. He lived in New York City in the 1800s. In 1882, Johnson had an idea. It would change the look of Christmas forever.

    Johnson worked as a boss at a technology company. In 1871, he hired a young man to work for him. The man's name was Thomas Edison. Edison was a great worker. He came up with many new ideas. Later, Edison left to start his own company. Johnson followed him. Johnson started turning Edison's ideas into money. In 1880, Edison invented the light bulb. No one knew how much it was worth. At the time, most homes did not have the electricity to power it. However, Johnson helped start a company to sell the bulbs.

    Before long, Mr. Johnson had a bright idea. Christmas trees were very popular. They were so beautiful because of their candles. Flickering (闪烁的) flames were perfect for Christmas. But they were also dangerous. They could easily start a fire.

    Mr. Johnson thought of a way to fix this. He set up a Christmas tree by one of his windows. Then he took 80 colored light bulbs and hung them around it. The lights were red, white and blue. People on the street stopped to look. They admired the shining Christmas tree. It was so popular that Johnson made it a tradition. Each year he added more lights. In 1884, there were 120 light bulbs on his tree. The lights were not cheap. In 1900, a string of 16 bulbs cost $12. That was a lot of money back then, because people made less. In today's money, that is about $350. But over time, they started to cost less. By the 1930s, colored light bulbs were everywhere.

    Today millions of light sets are sold in America each year. They light 80 million homes. Some of them are now used for other holidays too. They are used on Halloween and Valentine's Day. But it all started with Johnson's Christmas tree.

    People need to relax and enjoy themselves. One way they can have a good time is to watch a baseball game or another sports event. Even thousands of years ago, groups of people gathered to watch skilled athletes (运动员).

    Over 2000 years ago in Greece, certain days in the year were festival days. These were holidays when people stopped work and enjoyed themselves. They liked to watch athletes take part in races and other games of skill.

The most important festival was held every four years at the town of Olympia. It was held in honor of the Greek god Zeus (宙斯). For five days, athletes from all parts of the Greek world took part in the Olympic Games. At the Olympic Games, people could watch them box, run, jump and so on. There was a relay race between two teams of men in which a lighted torch (火矩) was passed from runner to runner. The Olympic Games were thought to be so important that cities which were at war with one another had to stop fighting. People were allowed to travel to the games safely. Thousands of people came to Olympia from cities in Greece and from her colonies (殖民地) in Africa, Asia and Italy. They met as friends to cheer their favorite athletes and to enjoy themselves.

    Some jobs are so demanding that there is not a free moment to do something else than to recover and rest. Most physicians have great difficulty starting or even maintaining a hobby. But there are exceptions.

    Take Menno Baars for instance. He works full time as a cardiologist(心脏病专家)in a hospital in Holland. "Full time" might still be an understatement-as a cardiologist he spends about 60 hours a week in the hospital. However, after a long day of work, he likes to come home and spend hours doing what is his great passion: painting.

    How can he find the time and energy to live a life that few others can pursue?" "Actually it is quite simple. If you like what you do, you will find a way to do it. Don't get me wrong. I love cardiology, but it is not a very creative profession," says Baars."It is a specialty that is based on strict treatment guidelines, without much room for your own ideas and creativity. That is why painting as a hobby is so wonderful. There are no rules and I can do whatever I want."

    Although there are no rules in painting, for Baars it is still some sort of a custom. The only thing that reminds the painter Baars of the cardiologist Baars is his white coat and his surgical gloves which he wears every time he is painting." I sometimes start at 10 at night and can continue working until 4:30 in the morning and still make it to work on time that same day," says Baars."That is the advantage of my training as a medical specialist. I get used to making crazy hours and long nights."

    You would think that someone who is so driven by his passion for painting was already fascinated by art as a little kid." Not at all," says Baars unexpectedly." I never dreamed of becoming a painter. My parents expected me to finish college and pursue a professional career. I only realized my passion for painting after having completed medical school. Once I was attracted by a painting of Miro, but could not afford it. So I decided to paint myself. I just started painting lines, but within minutes a beautiful dove was on the canvas. I suddenly realized this is what I want to do."

    A successful doctor. A successful painter. It seems unfair to have the two identities in one person. What do his fellow cardiologists think of his passion for painting? "They accept it and actually appreciate it as well. You see, if I was a cardiologist who provided suboptimal(未达最佳标准的)care for his patients，they would not agree. My chairman told me a few years ago in the hospital that he would rather see me reading cardiology books at night than see me holding a paint brush."

    "I used to pack a lot of ideas into each painting-different shapes，colors and so on. I still have tons of ideas, which is not the problem. But I do strive for more simplicity. To depict a simple idea clearly is my goal. Also my technique has improved over time. When I started out, the paint would sometimes flake(剥落)if the basis was not good, but that doesn't happen anymore these days."

    Menno Baars never has any doubts when he is painting. However，he does like the response he gets from the most important woman in his life. His wife is the first to see each newly-finished painting." Sometimes when I finish a new painting in the middle of the night, I wake her up to see if she likes it. She doesn't always like to be woken up, but she always gives an honest answer.

    Even if she doesn't like it, for me the painting is finished. I won't change it afterwards. It is more of the feeling that once my wife has seen it, it is ready to be presented to the rest of the world."

    A science teacher from rural Kenya who gives away most of his salary to help poorer students has been awarded the world's best teacher and $ 1 million, beating 10,000 nominations from 179 countries. Peter Tabichi, 36, a maths and physics teacher at Keriko secondary school in Pwani Village, has won the Varkey Foundation Global Teacher Prize 2019.

    Tabichi gives away 80% of his income to help the poorest students at the poorly-equipped and overcrowded school who could not otherwise afford uniforms and books. More than 90% of his students are from poor families and almost a third are orphans or have only one parent. Drug abuse, teenage pregnancies, leaving off their studies, young marriages and suicide are common. Students have to walk 7 km along roads that can become impassable in the rainy season to reach the school and the area can be affected by drought and starvation.

    Despite only having one computer, a poor Internet connection and a student-teacher ratio of 58:1, Tabichi started a "talent nurturing club" and expanded the school's science club, helping students design research projects of such quality that many now qualify for national competitions.

    His students have taken part in international science competitions and won an award from the Royal Society of Chemistry after using local plant life to generate electricity. Tabichi and four colleagues also give struggling students one-to-one tuition in maths and science, visiting students' homes and meeting their families to identify the challenges they face.

    Accepting the prize, Tabichi said Africa's young people would no longer be held back by low expectations." Africa will produce scientists, engineers and entrepreneurs whose names will be one day famous in every corner of the world." he said.
