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”

    When I graduated from college I dreamed of being a television news reporter. Having no experience, I had to work in a small town until I finally got my big break in the form of a job in Boston. I made it.

    Soon, reality set in. I was too often sent to run after accused criminals out of courts, waiting outside of crime scene tape or at the doorstep of a family still crying for tragedy (悲剧). My breaking point came the day I accidentally informed a young woman that her mother died. It was the worst day of my professional life and the day I decided I no longer wanted to shine a light on these stories. My career was ebbing, and at the same time my personal life was too-I divorced.

    My mom had always told me “When you're feeling extremely upset, go help someone else.” So I started seeking out stories of people who had been in the news under tragic circumstances but were doing something inspiring with their lives: a young girl who was paralyzed (瘫痪的) by an accident but was uplifting her classmates with her positive spirit, a blind and autistic (自闭的) musician who learned to play 27 instruments, a disabled soldier who opened his own art studio. I started to tell and promote stories like them.

    Over the last 10 years I have discovered my kindness gift: my ability to see the beautiful side of a person and reflect it back to them and the world. In telling stories of people turning their own hurt into acts of helping others I have become more sympathetic, more grateful and kinder. I have learned kindness is who we are, that our power for it is limitless and that, as we shine a light on it, it grows.

    Christmas was near a season that we took seriously in our house. But a week or so before the 25th, my father would give each of his children $ 20. This was the 1970s, and $ 20 was quite a bit of money.

    But I saw it differently. My father trusted me to have the smart to spend money wisely. Even better, he gave me the means to get it. On a very basic level, my father was giving me a shopping spree (狂欢) every year.. But he was also giving me charge over my own fun, trusting my ability to manage money and making me feel like a grown-up. He didn't buy me Sherlock Holmes, but he gave me the means to walk into the bookstore and choose it for myself, so it felt like a gift from him.

    My mother had a gift for giving me what I needed, usually right at the moment I needed it most. This was when I was 25, I failed at being an adult on my very first try. I had quitted my previous job but had no new one. But when my mother paid me a visit, I put on a good show, telling her I had started my own company.

    My mother knew that I was trying hard and failing at that time. It wasn't until after she left that I noticed at the foot of my bed an envelope thick with cash. She knew how desperately I needed it. She knew that had she just shown up with groceries, or offered to pay my rent, she would have made me feel much worse. The cold, hard cash meant she was helping me. And, funnily enough, the distance with which she gave the gift felt like she was giving me space to fix my life and preserve my dignity. My mother and father both did the same thing. One was giving me the means to take my own decisions, and the other was giving me a second chance when those decisions had cost me dearly.

    Your next car could have two seats, three wheels—two in front and one in the back and a top speed of more than 100 miles per hour. Elio Motors plans to make such a tiny car named the Elio. Its two seats sit front and back instead of side by side. The driver is positioned in the center with the passenger directly behind.

    The starting price for the car is just $6,800. It has only one door, on the left side, which cuts a few hundred dollars off the manufacturing costs. Having three wheels also makes it cheaper. It has air conditioning, power windows and door locks and an AM/FM radio. More features can be ordered through Elio's long list of suppliers. Elio will also sell the cars directly through its own stores and not through franchised dealers (特约经销商).

    Paul Elio dreamed as a kid that he would one day own a car company called Elio Motors. In 2008, tired of high gas prices, he started working on a car that burns gas in a more effective way. Equally important to him was creating US manufacturing jobs and making the car inexpensive enough to attract buyers who might otherwise be stuck in their old, unreliable cars. "Whatever matters to you, this can move the needle on it, he said.

    Already, more than 27,000 people have reserved one. Paul hopes to make 250,000 cars a year by 2020. So far, reservation holders are those who will use the Elio as a second or third car for work. Paul Elio believes the car will interest college students as well as used-car drivers who want something newer and more reliable, though.

    You have just won ten million yuan in a lottery (彩票) - how would you spend it? Before you know it, ten minutes had gone on daydreaming. There is a time and a place for daydreaming, but we don't have much control over that. Isn't it worrying that an estimated 30 to 50 percent of our waking time is spent daydreaming? What if your dentist is having that lottery daydream while removing your rotten tooth?

    Some studies suggest daydreaming makes us unhappy because we are not focusing on what is around us but are instead thinking about the past or future. However, a recent study published in the journal Neuropsychologica finds that mind-wandering can be of benefit to us. The researchers measured the brain patterns of more than 100 people using an MRI (核磁共振成像) scanner. This data was compared with tests on creative ability and a questionnaire on how much their minds usually wandered. Those whose minds wandered the most scored higher in creative ability tests and had more efficient brain systems measured in the MRI machine.

    Being efficient at mind-wandering means you can zone out and then naturally switch back in without missing any important point or step. Christine Godwin, the lead author of the latest study from the Georgia Institute of Technology, says that if you are focusing on difficult tasks, your performance will drop if your mind wanders. “But when tasks are easy, people who have high cognitive ability can let their minds wander because it does not affect their performance. You may be thinking about upcoming goals or problem-solving. These are some of the positive sides to mind-wandering."

    Mind-wandering can vary between being more practical or more emotional. What mind-wandering seems to be best at, researchers say, is coming up with new solutions to old problems. So, it's not always a waste of time!
