In a recent announcement, Harvard and the Massachusetts Institute of Technology（MIT）said that they have joined forces to offer free online courses in an effort to attract millions of online learners worldwide.

    Beginning this fall, a number of courses developed by teachers at both universities will be offered online through a new $60 million program, known as edX. “Anyone with an Internet connection anywhere in the world can use our online courses,” Harvard President Drew Faust said during a meeting to announce the plan.

    MIT has offered a program called OpenCourseWare for ten years that makes materials from more than 2,000 classes free online. It has been used by more than 100 million people. In December, the school announced it also would begin offering a special certificate, known as MITx, for people who complete certain online courses. Harvard has long offered courses to a wider population through a similar program.

    The MITx will serve as the foundation for the new learning platform.

    MIT President Susan Hockfield said more than 120,000 people signed up for the first MITx course. She said Harvard and MIT hope other universities will join them in offering courses on the open-source edX platform.

     “Fasten your seatbelts,” Hockfield said.

    Other universities, including Stanford, Yale and Carnegie-Mellon, have been experimenting with teaching to a global population online.

    The Harvard-MIT program will be monitored by a not-for-profit（非盈利的）organization based in Cambridge, to be owned equally by the two universities. Both MIT and Harvard have provided $30 million to start the program. They also plan to use the edX platform to research how students learn and which teaching methods and tools are most successful.

    Jack Ma is the founder and CEO of Alibaba Group. He was one of the 100 global "future leaders" of the 2001 World Economic Forum and the "commercial leader" of 2001 elected by US Commercial Association of Asia.

    Born in the city of Hangzhou, Zhejiang Province, Ma graduated from Hangzhou Teachers Institute in 1988 (he failed the entrance exam twice) and became a lecturer in English and International Trade.

    In 1985, a one-month visit to see an Australian pen pal he had met in Hangzhou changed his life. "Everything I'd learned in China was that China was the richest country in the world," he said. "When I arrived in Australia, I realized it's totally different. I started to think you have to use your own mind to judge, to think." After his return, Ma became the chairman of the Students' Union of the whole city.

    Jack Ma founded Alibaba.com in 1999, a China based business to business marketplace site. In 2003, Alibaba launched Taobao.com, a consumer to consumer auction (消费者拍卖) website similar to eBay.

    Ma said that he got most of his ideas while taking very long, hot showers. He likes to spend time walking his four dogs and playing chess and poker. He said, "I've learned a lot of business philosophy by playing poker."

    Looking ahead, Ma said that he dreamed of using his group's resources to improve the lives of all Chinese people, especially the 900 million farmers. "There must be some way of using our experience, our know-how, and make their life easier," he said.

    My grandfather grew up in war-torn Europe. When German soldiers occupied his hometown, the thriving city of Tarow, Poland, he refused to obey them and eventually joined the Soviet army to fight for his country's freedom. “Stand straight, stand tall,” he told himself.

    After the war, in 1947, he boarded a boat for Manhattan. He was hungry and suffering from seasickness. All alone in a new country, he was frightened about his future. Still, he marched head-on into the hustle of the streets of New York. Soon he met other European immigrants, each of them trying to find his or her own way. If they could do it, why couldn't he? “Stand straight, stand tall,” he would remind himself.

    Thanks to the help of a loyal and trusting friend, my grandfather gained a jewelry booth on Canal Street, New York City. He once told me how nervous he was on that first day of work. He was not only trying to learn this tough new business, but also a new language.

    To his surprise, the men in neighboring booths－who could have taken advantage of him－offered their help and advice. Within months, my grandfather was commanding his spot behind the counter, selling diamonds and cultured pearls as if he'd been doing it his whole life.

    Stand straight and stand tall.

    In later years, my grandfather would take both my mother and her sister down the aisle at their weddings. As he stood with each of them, he thought about their new beginnings, and of the adventures and journeys they would experience together. He also thought about the children who would one day carry on his family name.

    I am so proud to be one of those children. Listening to my grandfather's remarkable experiences has changed the way I view my own life.

    We're often reminded of the importance of preserving the planet as we see it for future generations—and children at St Oswald's Primary School in Chester certainly agree.

    Nine-year-old Isobel Kelleher from the school's Hummingbirds class thinks adults need to take note. “Sometimes they can be busy and I don't think they think they can make a difference，but if everyone does a little bit it all adds up，” she tells HuffPost UK.“ We started looking at plastic pollution in our oceans and the things like plastic bags and broken down pieces of plastic that are polluting them.” she says.“ Fish can eat the plastic and they can die，or we might even eat the fish ourselves.”

    Mr Timms，Isobel's teacher，has been spearheading a new project at the school which lets children loose creatively to raise awareness of the need to be more environmentally friendly. The entire Hummingbirds class，which is made up of 9 and 10-year-old pupils，has been busy writing poems and creating online video adverts to warn adults about the serious situation of our oceans and wildlife.

    Mr Timms thinks children have an important role to play in teaching us how to take care of the things around us. We sometimes overlook how much we can really learn from children.” he says.“ It has been really hard to believe having parents come in saying that their children have been asking them to stop using plastic，and to recycle more，and even stopping them using plastic straws.”

    Mr Timms is proud of his Hummingbirds class.“ The message that they would like to send to the world is simple stopping this isn't someone else's job，and it won't be OK if we just leave it.”

    My favourite book is The Adventure of Tom Sawyer by Mark Twain. Tom lives with his aunt Polly in a quiet street of St. Petersburg, Missouri. He's a lively and clever young boy, and he finds himself in many exciting adventures. He runs away with his two friends, Huck Finn and Joe, to an island in the middle of the Mississippi River for several days. With Huck he goes looking for treasure, with Becky he gets lost in a cave. And finally, they find a box of gold.

    My favourite scene in the book is when everyone thinks Tom is dead. He decides to go to his own funeral. He hides and watches for a time and then suddenly he appears. Everyone is astonished to see him but they're also pleased to see him alive.

    Tom is the hero of the story, but there are other important characters. Huck is an outsider and everyone is afraid of him. Becky is pretty with fair hair, Joe is Tom's best friend. And Injun Joe is the bad man of the story.

    The theme of the story is about children growing up. It describes how strangers are seen in small towns of America. Finally, it talks about freedom, social rules and how people are punished for bad behaviour.

    Why do I think The Adventure of Tom Sawyer is a great book? Mark Twain wrote the story in 1876, but it's still read and loved by people all over the world today. And although it's only a story, Twain wrote it in the everyday English of the southern states of America in the 19th century, so it sounds very real. Today it's thought to be one of the greatest books in American literature. Go on—read it! I know you'll enjoy it, too.

    It was at least two months before Christmas when nine-year-old Rose told her father and me that she wanted a new bicycle.

As Christmas drew nearer, her desire for a bicycle seemed to fade—or so we thought, as she didn't mention it again. We bought the latest fashionable Baby Sitter's Club dolls, a holiday dress and some beautiful story books. Then, much to our surprise, on December 23rd, she proudly announced that she "really wanted a bike more than anything else."

    It was just too late, what with all the details of preparing Christmas dinner and buying last-minute gifts. We could only think of the bicycle and the disappointment of our child. "What if I make a little bicycle out of clay and write a note that she could trade the clay model in for a real bike?" Her dad asked. The theory, of course, being that since that is a high-ticket item and she is "such a big girl", it would be much better for her to pick it out. So he spent the next five hours painstakingly working with clay to make a tiny bike.

    Three hours later, on Christmas morning, we were excited for Rose to open the little heart-shaped package with the beautiful red and white clay bike and the note. Finally, she opened it and read the note aloud.

    She looked at me and then at her dad and said, "so does this mean that I trade in this bike that Daddy made me for a real one?"

    Beaming, I said, "Yes."

    Rose had tears in her eyes when she replied, "I could never trade in this beautiful bicycle that Daddy made me. I'd rather keep this than get a real bike."

    At that moment, we would have moved heaven and earth to buy her every bicycle on the planet!
