    With his unique black mane (鬃毛)and impressive stature(身材), 13-year-old Cecil was a popular tourist attraction at the 3.6 million-square-acre Hwange National Park(万基国家公园) in Zimbabwe (津巴布韦).

    Cecil was head of a pride of lions that includes 12 cubs(幼崽), but the well-known lion was shot and killed in early July by American dentist Walter J. Palmer.  

Cecil's death has already sparked an international outcry (强烈抗议) with many calling for an end to hunting endangered animals and for Palmer to be extradited(引渡) to Zimbabwe to stand trial.

Professor David Macdonald, the head of the Oxford University research program that monitored the daily movements of Cecil and dozens of other lions, is deeply saddened by Cecil's death. Macdonald hopes the death can inspire the public to take an interest in lion conservation.

    Macdonald says many of the lions tracked by the program have been shot  and killed. “The background to this story is that there is a crisis for lions throughout much of Africa.” He says.

    African lion populations have fallen almost 60 percent over the past thirty decades, and as few as 32,000 of them remain in the wild, according to the International Fund for Animal Welfare(国际爱护动物基金会).

“And as troubling as it is, the rarer these hunted animals become, the more hunter s are willing to pay to kill them,” said Jeff Flockedn, the fund's North American regional director.

    In addition to excessive hunting, lions throughout Africa also continue to face threats that include conflicts with local farmers, loss of habitat and risk of traffic and railway collisions(碰撞).

    For the past four days, the streets of India have been brightly lit and full of festivities. Millions of people around the country have been celebrating the festival of Diwali.

    Diwali has been celebrated in India for hundreds of years. It takes place each year in either October or November. Although the holiday lasts only one night, people continue to celebrate for several days.

    People light oil lamps during the festival. In the tradition of the Hindu religion, the lamps are meant to celebrate the victory of light over darkness and good over evil (邪恶). The holiday also celebrates the start of a new year in the Hindu calendar. But Diwali is an important festival in many other Indian religions as well, including Sikhism and Jainism. In a country of more than 1.2 billion people and different religious beliefs, Diwali is a celebration that touches everyone.

    Diwali means “rows of lamps” in Sanskrit, a language used in many Indian religions. During the festival, families and friends come together to light the oil lamps，which are called diyas. Then they put the lamps in rows outside their homes and temples.

    As in other cultures' winter holidays，sweets and gifts are also a big part of Diwali. Neighbors and friends share treats, called mithai, and exchange presents.

    Employers often use the holiday to express appreciation for their workers. This year, a businessman even bought cars and houses for some of his employees!

    The Diwali spirit can be felt outside India as well. Indians in countries around the world, including the U. S. and Canada，are also celebrating the holiday this week.

    Saber Miresmailli was on vacation in London when, caught in a bit of traffic on London Bridge, he decided to take a photo of Tower Bridge.

    “I noticed the couple,” he said. “At that moment, I did not see anyone from the wedding party or a photographer with the couple, so I took several pictures. Usually, my pictures are not very good given the fact that I don't use flash and I don't stop to compose (构图)-so when we get back after two weeks, I was very surprised to find this one turned out so well.”

    Miresmailli said, “I thought to myself, if it was me getting married, I would have wanted the picture.” So he posted the photo on Facebook and attached a few friends with the hope of finding the couple and passing them the picture. What happened next, he said, “was crazy”. “I received more than 2,000 requests from perfect strangers and lots of positive and negative emails.” Until this afternoon, almost 230,000 people had shared his Facebook post on the photo.

There's also been an uncertain identification of the couple. It's likely that their names are Laura and James. “If it's the right couple,” Miresmailli said, “they are on their honeymoon in Bali and have no idea about the photo. I believe they will be shocked to find out about their fame.”

    Miresmailli said he's been drowned by the interest in the photo. “I just want to give them their picture and go back to work and tend my tomatoes,” he said.

    A few months after Wu Xingu was congratulated by teachers for graduating from the university, the 23-year-old has been making his dream of relieving tens of thousands of teachers in China from drowning in marking papers(改卷) a reality.

    Yitiku, an online software system based on Wu's idea, eases the workload of teachers by doing many of the functions that they did, such as selecting the test questions, forming an exam paper, and preparing exercises for the students.

    The features of Yitiku may sound quite simple, but this idea won his company millions of dollars from China's Internet giant Tencent in January. The unexpectedly successful fund raising story became a popular conversation starter among the people in the education business.

    "I can say it's quite an achievement for me and our company. As far as I know, I'm the first CEO born after 1990s that Tencent has invested (投资) in, and we are the first online education company they have invested in." Wu Xingyu told China Daily.

Different from other online companies that treat students as clients (客户), Yitiku has chosen teachers as their focus. "We make the work of teachers easy. Usually it takes two to three hours for them to prepare a new exam paper. Now it's just three clicks." said Wu. He is quite satisfied with the major feature of the software.

    Sitting in his 10-square-meter office in Zhonguancun, a hub of innovation (创新) in Beijing, Wu looks confident and chatty when talking about his business. His fast-speed answers give people an impression that he has years of experience in the online education sector. The fact is that he had been putting most of attention in directing courses at an art college until about a year ago.

    Australia

    If you seek a life on the beach, in a great climate with friendly people, Australia might be your best bet. With thousands of volunteers already signing up to leave for Australia during the holidays, it will be a very popular option.

    Brazil

    Kenya

    Kenya is the destination for those seeking an African experience. Generally volunteers in Kenya work in orphanages (孤儿院) or with local children living in slums (贫民窟). There is a great demand for volunteers in Africa because many people live in poverty, so if you truly feel like making a difference to a community, Kenya should be at the top of your list.

    Costa Rica

    Golden sandy beaches, clear coastlines and beautiful cities are what Costa Rica is all about. Because of its small size, you can see a lot of the country in just a short time. You can really make the most of your time as a volunteer. A lot of work is needed with wildlife and ecological work, so if you want to look after turtles (海龟) on the beach, Costa Rica could be just the place for you.
