In 2011, when British photographer David J. Slater was visiting a park in Indonesia, his camera was taken away by a group of black monkeys. The result was hundreds of monkey selfies(自拍照). The best ones show a female monkey smiling toothily for the camera. Slater then sold the photos and they became popular on the Internet.

    Nobody knew they would create a copyright battle some years later.

Last month, Wikimedia Commons put the monkey selfies online under a collection of free photos without Slater's permission. Slater asked the website to take them down since he owns the copyright.

    However, Wikimedia Foundation-the organization behind Wikimedia Commons-refused Slater's request. They said that according to US copyright law, whoever pushes the button on the camera owns the copyright to the photo. It was the monkeys but not Slater that pushed the button. What's more, monkeys don't own copyright. "US copyright law says that works that come from a non-human source(血统)can't ask for copyright, " said Katherine Maher, Chief Communications Officer of Wikimedia.

    Slater argues that the pictures belong to him as they were taken from his camera. He said he bought the cameras, he spent a lot of money to travel to Indonesia, and it was his carelessness that allowed the monkeys to take his cameras away. All these have made him the author of the picture, no matter who pushed the button. In a sense(在某种意义上), the monkeys could be regarded as his assistant, Slater said.

    As of now(到目前为止), there has been no result in the Monkey Selfie case. Who do you think will win this interesting battle?

    Alf is a big soccer fan. At school, there are lots of children playing soccer. Alf really wants to be a soccer star, but he thinks he isn't good at soccer. He feels very sad. He always thinks about how to be a great soccer player.

    One day, Alf went to watch the school soccer match on the playground with his friend. There were many students watching the match. Suddenly Alf shouted, "Look out!" He jumped up and made a very good save(救球)！

    All the soccer players and the coach cheered for him. "What a good save, Alf! You're the best!" His friend said. The soccer coach came to him and said, "Alf, come with me." Alf stood in the goal(球门) and the coach took a shot(射门). It was a good shot, and Alf saved it. Alf saved the next shot, too; and the next one. All the students cheered. Now Alf knows he is a very good goalkeeper. He is good at playing soccer.

    One day I happened to meet an Englishman in the street and soon we began to talk. As I was talking about how I was studying English, the foreigner seemed to be very surprised, gently shaking his head and saying "You don't say!". I was puzzled, and I thought, "Perhaps this is not a right thing to talk about." So I said to him, "Well, shall we talk about the Great Wall? Have you ever been there?"

    "Certainly! Everyone back home will laugh at me if I leave here without seeing it. The Great Wall is wonderful!" "Yes, it is one of the wonders in the world. And people of many countries have come to visit it." As I went on telling him more about it, he stopped me again, "You don't say!"

    I couldn't help asking, "Why do you ask me not to talk about it?"

    "Well, I didn't ask you to do so," he answered, greatly surprised.

    "Did you say 'You don't say!'?" I asked again.

    Hearing this, the foreigner laughed loudly. He began to explain," 'You don't say!' means 'Really'. Perhaps you know little about English idioms."

    Wow! How foolish I was! Since then I have been careful with English idioms.

Known as "soft gold", Gambiered Canton gauze (香云纱) is the only silk fabric (织物) that's still hand-dyed (手染的) using natural plants in the world today.

The skill has a history of more than 500 years. In 2008, it was listed as a national intangible cultural heritage (国家非物质文化遗产). Ouyang Yongze is an inheritor of the dyeing skills from Guangdong. The man started learning the skills in 2017.

The dyeing process includes 30 steps. It can take up to six months and is done by hand with materials from nature. "The plant shuliang (薯莨), river mud, sunshine, and grass are all important in dyeing," Ouyang told China Daily.

To dye the fabric, workers put it in shuliang juice and let it dry on the grass. They repeat this many times until it turns brownish yellow. Then, they put river mud on it to help shuliang react fully. After washing and drying it again, the fabric turns black!

Mastering the skills is difficult, according to Ouyang, who put full effort into controlling the density (浓度) of shuliang juice. "Too much may cause color loss, and too little may nor lead to a dark enough fabric," he said. "Better control of the density comes after many failures."

Also, the job can be really tiring as workers have to be at work in the sun for 8 hours each day. Only a few people work in the industry, and skilled masters are getting older as fewer young people take part.

Considering this, Ouyang works harder to develop the traditional craft. He has got together other dyeing skills such as tie-dyeing (扎染法) and batik (蜡染) and has worked with famous fashion designers. They turn the silk into both traditional and fashionable clothes that are popular worldwide. He thinks this can help make the craft stay alive and drew people to the industry.

①Everybody enjoys acts of kindness (善.举). But can you explain why? Some people think kindness is something out of love and care, while others believe it is just a tool to make us more popular. But research shows that being kind can activate (激活) an area of the brain called Striatum. Research also shows that kindness improves people's moods(情绪). But why and how does it happen? Here are a number of different ways.

②Firstly, being kind can make someone smile. If you see yourself smile in a situation, people around may be smiling too, especially for your close friends and family. A kind act makes someone who is sad feel better. It can also make ourselves feel good.

③Secondly, being kind starts or develops a social connection with others. Kind acts like buying someone a present make friendships stronger. Research has shown that spending money on others may help you get a stronger feeling of happiness than spending it on yourself.

④ Thirdly, in another research, even children in their first year of secondary school know how being kind makes them feel happy. If one person is kind, he or she makes others in the group kind. It also lifts everyone's spirits.

⑤Lastly, the story doesn't end here. Being kind may improve your mood, but research has also shown that if you're in a good mood, you can act much more kindly. This makes it a wonderful two-way relationship, doesn't it?
