Rupert Isaacson was born in Africa, and grew up in London and in the English countryside, where he discovered his love of horses. Because he grew up hearing so many fascinating memories about Africa from his parents, he went there and lived with the people called The Bushmen of the Kalahari Desert.

    By the year 2000, Rupert was already working as a reporter, writing articles and guidebooks about Africa and India. He met his wife Kristin in India. Today, they live with their son, Rowan, in the US. But Rupert faced the greatest challenge of his life when, at the age of two, Rowan was

diagnosed (诊断) with an illness that influenced his ability to communicate with others.

    Rupert discovered that spending time with horses and riding them was helping Rowan. But unluckily, the Bushmen of the Kalahari do not have horses. So the family set out for Mongolia, where horses have been important for long. Rupert has written about this journey to help his son in his book Horse Boy, and he has produced a documentary of the same name. In the film, people have the chances to see the family travelling in Mongolia, riding horses and meeting healers (治疗师) in order to help Rowan.

    Because working with horses has helped Rowan, Rupert set up The Horse Boy Foundation on his farm in Texas. It is a school that teaches people how to use horses for healing. Besides writing another book, The Long Ride Home, about travelling with Rowan to Africa, Australia and Arizona in the US, Rupert has also produced the documentary Endangerous, with Rowan as host, about dangerous animals that are endangered. Rupert Isaacson has managed to discover the secret of turning one challenge into many achievements.

    For years I went to school by bus, so I met many "familiar" strangers. We took the same bus but didn't know each other's names. I used to think it was impossible for us to be true friends. How wrong I was! Smiles from the "nameless" people have changed my thought.

    The first time on the bus, I saw different faces. As days went on, we hatted like old friends.

    But I felt it a pity that I was unable to set up the same friendship with a silent girl in the front of the bus. Her old clothing suggested that she didn't have much money, but she always took a cup of water for the driver. I guessed she was a kind girl. But why did she sit in silence instead of talking with us? Why did she never reply to our friendly greetings? Couldn't she smile?

    Then, one evening, I got the answer. I walked to the park nearby and found the girl sitting alone under a tree, lonely and sad. I greeted her with the same warm smile that had shown to her all these months, but this time her face turned red, then a shy smile appeared. As soon as she began her first words, I understood why she hadn't spoken to us before. Talking was hard for her.

    I heard her story. Her parents worked hard somewhere. She lived with her disabled grandparents. She said, "I can't express myself very well. Most of the time, I can't say what I want to say I have no friends but. You always smile at me like an angel… so I also want to smile." That evening, we exchanged our names and we said goodbye like old friends.

    The smile is the key to opening the door of heart; it can break the cold walls in front of us.

    Do you know the astronaut Chen Dong? He and another astronaut Jing Haipeng stayed in space for more than 30 days from October to November in 2016. During the days, they, did some experiments in space. For example, they tried to plant vegetables there.

    Chen Dong was born in Henan Province in 1978. When he was a child, he wasn't a good student. When he was in Grade 3, he made the vegetables at school dirty for fun. The vegetables were a gift to the teachers from the school, He was very afraid after that. However, his teacher wasn't angry with him. "You have to think about others when you do such things," the teacher only said.

    After that, Chen became a good student. He later became the class monitor, In 1997, he joined the PLA Air Force(中国人民解放军空军). With a safe flight record of 1,500 hours as a pilot, Chen became a member of the Shenzhou-11 mission(任务) in June, 2016.

    Before flying to space, Chen told his twin sons, "Dad is going out. When you look up at the sky and see a shining star, I am probably there, and say hi to me."
