South Africa is a multiethnic society encompassing a wide variety of cultures, languages, and religions. It has 11 official languages. If you want to say hello, it's "sawubona" in Zulu, and "hallo" in Afrikaans. Now, South Africa's school children may start using "ni hao" to say hello.

    The country's education minister says, the nation is adding the Mandarin language teaching in some schools. Mandarin is the official spoken language of China. That country is a major trading power for South Africa.

    A recent agreement between the two nations centers on five areas of cooperation. They include development in basic education, school books and lessons, mathematics and science, teacher training and career education and research.

    South Africa officials have not said how much they teaching Mandarin will cost. Troy Martens is an officials with South Africa's Ministry of Basic Education. She says the new partnership is extremely valuable.

    A public opinion study last year found that South Africans have mixed feelings about China. The survey showed 46 percent of South Africans do not like the spread of Chinese ideas and customs in their country, the results also showed that 60 percent dislike Chinese music, movies and television.

    But Ms Martens said Chinese trade is more important than those feelings. She said it is extremely helpful to learners in South Africa to study Mandarin as well as Chinese culture. And she said not every school will offer Mandarin.

    “Now this will not be compulsory, it will not be for every school, and it will not be for every child. But for schools that feel they have the capacity to offer Mandarin as a subject, we think it is a great opportunity for South African learners to be exposed to this international type of language,” said Martens.

    Lisette Noonan heads the 80-year-old Pretoria Chinese School in South Africa's capital. The school serves about 500 students from kindergarten to grade 12. Every student studies Mandarin.

    Ms Noonan says the school welcomes the new cooperation between South Africa and China. She said it is in the best interests of children to study Mandarin. She said that especially true with China becoming what she called “a huge economic power in the world”

    Custom tattooed fish (纹身鱼) may be big sellers at markets, but an animal expert say it is a cruel and potentially lethal practice.

    In Laitai Flower and Fish Market near the Lufthansa Center in Beijing, four of over 20 fish stores sell marine ornamental fish that are tattooed using laser (激光) guns with beautiful images in order to make them more attractive to customers. Many people just love these kinds of fish, which gives them a unique visual impression. The price of these fish ranges from 50-100 yuan. Some customers are willing to pay an additional 100 yuan to have Chinese characters tattooed on to the fish. The most popular characters are “zhaocai” (attracting fortune) and “fu” (blessing). The color of tattooed fish won't fade away, and the fish can be cared for as regular fishes:

    But Ye Zhenjiang, a professor from the Ocean University of China, said “the practice would damage a fish's mackerel scale, which is its protective layer. Although I haven't done any research on the impact of the laser on mackerel scale, it is obvious that the mackerel scale may be infected or even destroyed under the exposure of laser,” Ye said. “It's like tattooing a human being's body, and it breaks the physiological balance of the fish and damages: the skin's protective surface, It may even cause death among fishes which have thin mackerel scale.”

    A specialist in aquatic(永生的) animal study surnamed Xu, from the Beijing Fisheries Research Institute, said, “We have no specific regulations to prevent fish from being tattooed. An official surnamed Bai from the Fishery Surveillance and Administration Bureau(FSAB), said there is no study showing that the laser threatened a fish's health. He said a regulation on small animal protection, to be passed in the near future, doesn't include regular aquatic animals. He said the institution is only responsible for aquatic animals that are on the verge of extinction. He said tattooed fish are mainly from south China's Guangdong province because Beijing does not have the laser technology to tattoo a fish.

    “It's too brutal to tattoo pictures or characters on fishes, even if it makes them more beautiful,” many tropical fish buyers told METRO yesterday. “We would never buy fish like that and we prefer them with natural beauty.”

                                                                              Learning a Second Language

    Some people learn a second language easily. Others have trouble learning a new language. How can you help yourself learn a new language, such as English? There are several ways to make learning English a little easier and more interesting.

    The first step is to feel positive about learning English. If you believe that you can learn, you will learn. Be patient. You do not have to understand everything all at once. It is natural to make mistakes when you learn something new. We can learn from our mistakes. In other words, do not worry about taking risks.

    The second step is to practice your English. For example, write a diary every day. You will get used to writing it in English, and you will feel comfortable expressing your ideas in English. Several weeks later, you will see that your writing is improving. In addition, you must speak English every day. You can practice with your classmates outside class. You will all make mistakes, but gradually you will become comfortable communicating in English.

    The third step is to keep a record of your language learning. You can write this in your journal. After each class, think about what you did. Did you answer a question correctly? Did you understand something the teacher explained? Perhaps the lesson was difficult, but you tried to understand it.

    You must be positive about learning English and believe that you can do it. It is important to practice every day and make a record of your achievements. You will enjoy learning English, and you will feel more confident in yourself.

    Who could have imagined that a treadmill（跑步机）on wheels would one day become a thing?!? Lopifit is an unusual means of transportation that allows you to power an electric bicycle by walking on a treadmill.

Lopifit founder Bruin Bergmeester says it all started when he asked himself the question "How can I use a treadmill outdoors?" He finally came up with a new design, adding an electric motor, and the Lopifit was born. It's similar to an electric bicycle in that the motor only works when the rider puts power in as well. The Lopifit senses when you walk on the treadmill and uses the motor to turn a drive chain at the back of the treadmill, helping you reach a top speed of 17 miles per hour.

    To use the Lopifit, simply turn on the battery（电池）and use your foot to slide the treadmill backwards and start the motor. Then get on and enjoy the ride! If you need speed, just walk on the treadmill, and if you want to coast（惯性滑行）, all you have to do is stay still and admire the view. To stop, you have two hand breaks.

    The Lopifit first hit the streets in 2014 and, unsurprisingly, became a hit overnight. That was actually quite challenging for the company, because it started getting calls for orders, but it was nowhere near ready for mass production. The unique treadmill bicycle could be bought this year, and Lopifit is struggling to keep up with demand, although the price is up to $2,115.

    Some people consider this means of transportation stupid and unnecessary, although there is a very loyal fan-base of so-called Lopifitters. They simply believe that if you're going to walk, you might as well do it the old-fashioned way.

But the Lopifit does have the special advantage of helping you "walk" really fast without much effort, or walking at cycling speed, if you will.

    When I was growing up, Mother's Day was as important as Christmas.

    The energy around the house was always positive（积极的）, mostly thanks to my father who made sure that his kids appreciated their mother, We would clean the house, and Mum got breakfast in bed in the morning and didn't have to lift a finger all day. And in the evening, we went to a restaurant for a traditional Mother's Day dinner.

    What I learned from my father over the years, was that no matter what, he always put my mother before himself. He absolutely loved her and never let her forget that. And from my parents, I learned a thing or two about how to love.

    I maintain（保持） my father's Mother's Day tradition with my wife. Growing up, I learned that showing affection to the woman you love or who gave birth to you is an important part of life. You see, it goes both ways, and the love you have for your mother comes back to you again and again.

    Believing that and feeling it when you can may keep you from being lonely, even if your mum isn't close by or has passed away. There are a number of us who no longer have a mother in our lives, and truth be told, there are often times when I wish my mum were still here to comfort me. So instead, I remember the times she did just that. It makes me smile, and somehow, those memories of a more simple and loving life give me the comfort I'm looking for.

    My wife's mother is still around, however, and it's great to have that "mother energy" in my life still. Having this relationship with my mother-in-law is nice because it gives me someone to be there for on Mother's Day, and any other day of the year.

    If you are mum-less, you too should find a deserving woman in your life and celebrate Mother's Day with her. If you don't know anyone, there are plenty of lonely mums in rest homes who would enjoy your company for a couple of hours. The visit will make both of your days, and perhaps your lives, a little bit better.

    When Kevin Durant gave his tearful MVP speech in 2014, the NBA star made sure to thank one person who had been there with him from the very beginning: his mother. His heartfelt words about the sacrifices she made for Durant and his brother led to a lifetime movie about her journey as a single parent, The Real MVP: The Wanda Durant Story.

    Today, the NBA superstar's mom travels the country as a motivational speaker and philanthropist (慈善家). On Monday, she spoke at Thomson Reuters' in New York about her personal struggles to achieve financial stability and shared the financial advice she gave her son when he entered the league with CNBC.

    “I wanted him to realize he has worked hard," she says, "And it is OK for him to enjoy himself because of his hard work. But it is also imperative that he prepares for his future.” While she advised him to enjoy the rewards of his labor, she also wanted to make sure that her son knew the importance of financial planning.

    She told the audience that when she found herself a single parent to two children at 21, she couldn't follow the financial principles. Rather than planning for the future, she focused only on how her money could make ends meet for that moment.

Recently, Durant has teamed up with Laurene Powell Jobs for a new philanthropic program called College Track which is aimed at helping disadvantaged kids attend college. As part of the program, Durant has committed to donating $10 million to his hometown's public school system.

    Durant's mom says that in addition to his financial decisions, she is proud of his philanthropic work and his desire to help the community. “I thought giving back was always very important, and so we talked about that and he had seen that from us as a family and it's one of the things that I taught him," she says.
