New friends. Fresh lifestyle. Better career opportunities…Those are attractions of overseas study for young people in China. “Start early, finish strong,” some of them say.

    More than 300 universities from 27 countries and regions were represented at last weekend's international education exposition(展览).

    “I would say, no matter what people tell you, anything can happen.” That's the message Internet singer Austin Mahone says at We Day, an event for young people in Canada.

    When he was 14，Austin and a friend began uploading pop songs to musical websites.“I was just doing it because we had nothing to do, living in a small town.”

    “I'd check different websites for the hottest songs, and I'd record my own videos,” he explains. “That's how people began to find me online.”His videos got millions of hits and he signed with a record company. The result was the release of Austin's first album, Junior Year. While it seems like a sudden rise for the teenager, Austin admits the early days were not always fun. He says a lot of people thought badly of him for posting his videos online. Yet this didn't put him off.“I kept working hard. ”And the hits on his videos kept coming.

    Austin's achievement and spirit make him a perfect fit for the message of We Day. After all, Free the Children, the creator of the event, was founded to “enable youth to make changes.” Even Austin's unusual rise by way of the Internet fits with the way Free The children works and raises money.

    Because of Austin, his four million followers will learn about Free the Children. While Austin's presence certainly helps We Day, it's good for him, too. Austin gets to show himself as someone who volunteers his time and talent for a worthy cause and show that he cares about making the world a better place.

Five years ago, when I taught art at a school in Seattle, I used Tinkertoys as a test at the beginning of a term to find out something about my students. I put a small set of Tinkertoys in front of each student, and said: "Make something out of the Tinkertoys. You have 45 minutes today - and 45minutes each day for the rest of the week."

    A few students hesitated to start. They waited to see the rest of the class would do. Several others checked the instructions and made something according to one of the model plans provided. Another group built something out of their own imaginations.

    Once I had a boy who worked experimentally with Tinkertoys in his free time. His constructions filled a shelf in the art classroom and a good part of his bedroom at home. I was delighted at the presence of such a student. Here was an exceptionally creative mind at work. His presence meant that I had an unexpected teaching assistant in class whose creativity would infect（感染）other students.

Encouraging this kind of thinking has a downside. I ran the risk of losing those students who had a different style of thinking. Without fail one would declare, "But I'm just not creative."

"Do you dream at night when you're asleep?"

"Oh, sure."

"So tell me one of your most interesting dreams." The student would tell something wildly imaginative. Flying in the sky or in a time machine or growing three heads. "That's pretty creative. Who does that for you? "

"Nobody. I do it."

"Really-at night, when you're asleep?"

"Sure."

"Try doing it in the daytime, in class, okay?"

We are interested in the preservation of the biodiversity on Earth. What I've been working on is rats. Just looking at rats, you can understand continental drift and climate change. We've actually rediscovered rats that were thought to be extinct. Darwin was the last one to document them on the Galapagos Islands. People have gone there for hundreds of years and not seen one. In 1997, I went there with my mentor(导师) and another graduate student. Everyone thought I was crazy, why look for something that doesn't exist? They wouldn't even give us permits. Our plan was to stop on a beach for a day and then hike up to the top of an extinct volcano where very few people had been: We were on a picturesque, isolated beach. We set out the traps just to see what we might find. The next morning, I checked my traps! I immediately ran back to my mentor. When he looked in the mental trap—I will never forget his face— It looked like he'd seen a ghost.

I certainly understand the argument: "Who cares about an extinct rat?" but you have no idea what role that rat plays in that functioning ecosystem. People can appreciate beauty, so that's why people love pandas and want to keep them around. You never hear, "What good is panda?" Ecologically, these rats are much more important to their ecosystem than those pandas— not that I don't love pandas but we have to look beyond the big and beautiful.

    I teach conservation biology and evolution. In both you have to appeal to people asking "Why is this important to me?" Some scientists refuse to do that. That's my entire approach. I'll ask "How many of you had a family member who was in a tornado, hurricane or flood?" .And almost every hand goes up. Climate change is suddenly very personal, and now they want to hear what you are saying. You are not looking for sympathy for the rats but for a greater understanding of the system.

    Every summer, the Serengeti plains (平原) of Africa are worth visiting. Millions of wild animals begin their 1,800-mile journey northwards on their annual migratory (迁移的) route.

    In the month of November, polar bears in their thousands cross the Canadian Arctic, as they head towards the ice sheets of Hudson Bay. The sea ice that forms every winter is the key to the bear's managing to exist, for here they hunt for seals (海豹).

    The Great Bustard, one of the heaviest flying birds, migrates each year across Europe and Asia to its wintering grounds. Unluckily, these and other migratory animals are in danger from human activity.

    We have written several articles on climate change and the effect of rising ocean temperatures. Since 1979, ice sheets in the Arctic have gone down by 30 percent. What does this mean for polar bears? They are forced to stay on land for longer periods of time, which delays their search for food. As a result, bears today are 60 pounds lighter than what they were. Besides, smaller bears also produce weaker babies, and their chances of survival are at risk. In the plains of Africa, migratory animals like gazelles are traveling long distances for food, just to avoid falling prey (牺牲品) to humans who hunt them.

    In an unusual step, experts from 120 countries have agreed to protect 31 migratory mammals, fish and birds. The United Nation's 11th annual Conservation of Migratory Species of Wild Animals (CMS) was held in Quito, Ecuador. For the first time, 900 experts attended the conference, and the enthusiastic support shows the world is united in conservation (保护) efforts.

    What does getting on a protected list mean? Countries that have signed the agreement will be required to pass laws locally and work with other countries that fall within the animal's migratory path. Only one animal did not make the list. The African lion was rejected (拒绝) for lack of information of the countries where it lives.

    A photography exhibition by French artist San Bartolome entitled Moon Door Dreamers opened in the 798 Art Zone in Beijing on December 10, 2011, presenting a cross-cultural perspective (视角) on ordinary life in the capital city.

    Bartolome took these photos in August 2008, and produced a video named Two Worlds, One Dream. These works were displayed in Pingyao, an ancient city in Shanxi Province, under the title Beijing Midsummer Night Dream in September 2010.

    The moon doors serve as a keyhole through which one can catch a glimpse of a slice of Beijing life. He got his inspiration from one cycling trip to the southeastern suburb of Beijing, where he discovered a peculiar street along which a gray brick wall was built to cover the shabby bungalows. These cabins were mostly rented by migrant workers- peddlers, craftsmen, grocers and innkeepers.

    Born in 1950, Bartolome has worked as a photographer, stage director. Artistic manager, writer and diplomat. A noted Sinophile, Bartolome frequently visits China for photographic subjects. In the fall of 2003, he joined the French Embassy in Beijing as a cultural attache. His work experience in China from 2003 to 2015 further enhanced his awareness of and love for China.

    Bartolome not only loves Chinese culture but also the Chinese people. He thinks that Chinese people are kind, welcoming and diverse.

    Back from his bike ride to southeastern Beijing, he decided to shoot pictures about ordinary urban lifestyles. He observed dwellers carefully and made friends with them.

    After about 30 days and nights that he spent with these common migrants, he created a number of portraits. Meanwhile, he learned more about those rural migrants who earn their living in a city with which they are unfamiliar.

    He adopted an optimistic perspective to shoot the sights, and he borrowed the title of one of William Shakespeare s comedy works: A Midsummer Night's Dream.
