    He Jiang, a postgraduate（研究生）in biology. will become the first Chinese student to give a speech in the commencement(毕业典礼)at Harvard University on May 26, 2016.

    Given the highest honor by the university, He Jiang, who was born in a small village in Hunan province, said, "People in China often believe that it's useless to study and children from the countryside cannot be successful in the future. However, I cannot agree with them. Education can change a person's life. I hope my experience can encourage the students from the countryside to spare no effort in study and make their dreams come true."

    Different from many other families in the village, his parents never thought about finding a job in big cities and leaving their two sons at home without their care. His father was strict about their studies. He and his younger brother studied at home while the other kids in the village played in the fields. Unlike his strict father, his mother took her sons' side when her husband scolded the boys. She preferred to sit with her sons when they studied rather than chat with other women in the village.

    Getting the chance to speak at the commencement is no accident. During his first days in Harvard, it was quite difficult for him to follow the professors in class and he was speechless in campus because of his poor English. Instead of giving up, He Jiang spent all his free time on English. He also made friends with natives to improve his speaking English. One year later, he had little difficulty in class and soon became one of the top students in his class. With the encouragement from Professor Diana Eck. He Jiang decided to apply(申请）for the chance to speak at the commencement.“Few Chinese students had applied before, but I wanted to have a try. I just want to realize my idea of letting more people hear the voice from China and telling them that China is not what it used to be." said He Jiang. After beating three students from Harvard Kennedy School in the third and final round, He Jiang made it to get the chance to speak at the commencement.

    He Jiang will go to Massachusetts Institute of Technology after graduating from Harvard.

    Sydney Fredette has a lot of things to deal with. Not only is she a high school student, but she has also set up her own organization, Beary Merry Christmas. She volunteers to serve poor kids and families in Orange County in California, US.

    To remember her best friend who died of cancer nearly 10 years ago, Fredette decided to serve those in Orange County who are less lucky than she is. She began with the simple idea of collecting donated Build-A-Bears, the popular toy animal that is made by children themselves in the stores' workshops. Fredette then gave them as gifts to the homeless children in California.

    With donations at more than 100 bears a year, Fredette and volunteers in her organization hold activities every year. They not only give out the bears, but also many other things.

    Fredette now also holds other activities for Valentine's Day, Mother's Day and Halloween, providing the chance for her volunteer team to make a difference through the year.

    "I love making relationships with the people I serve." Fredette said. "The thanks they have, hearing their stories and seeing how happy they are, it's so cool."

    Future plans for Fredette include building a public food bank and providing a self-development class for students in her school who will soon attend college. Heading to college herself in the fall, Fredette is looking to stay local and continue to help out in her hometown. In fact, she was regarded as a "Dreamer & Doer" not long ago for her work in improving her community, along with 32 other high school students.

    Mickey is a cheerful boy. No one can make him angry. And he never says anything bad about others. Even his teachers think he is so special.

    One afternoon, Mickey invited his favourite teacher, Mr Anthony, to have a cup of tea at home. On his bedroom door, the teacher was surprised to see hundreds of small colour cards.

    "Some friends at school think I never think badly of anyone," Mickey smiled, "but that's not true at all. In fact, I was easier to get angry than all the other kids years ago. Then my parents helped me start a card collection. With each little card I put on the door, I can easily forget the bad thing." It was true. On these cards, Mr Anthony could read "fool", "pain", "anger" and some other bad things. That day they talked about many other things, but Mr Anthony never forgot the small colour cards on the door.

    From then on, Mr Anthony began his own card collection. He also encouraged his other students to do so.

    Mrs Green lives in a small village. Her husband is dead. But she has a son. He is twenty-one and his name is Jack. He gets work in a town and lives there. Its name is Greensea. It is quite a long way from his mother's village, and she is not happy about this, but Jack says," There isn't any good work for me in the village, mother, and I can get a lot of money in Greensea and give you some every week.

    One day Mrs Green is very angry. She gets on a train and goes to her son's house in Greensea. Then she says to him," Jack, why do you never give me a ring?

    Jack laughs and says," But, mother, you don't have a telephone.

    "No, she says, "I don't have one, but you have one.

Buying clothes in a busy shop can be a bad thing. But shopping online can be a bit hit-and-miss. Sometimes you can't find what you like. So shopping online is not an easy thing. This has led to a number of companies' owners to come up with a new idea—interactive mirrors (互动试衣镜) in shops that let you try on different clothes with different colors and patterns (样式) without putting on or taking off by yourself.

Now the scientists have made the latest interactive mirrors in the USA. The interactive mirror uses a new kind of technique (技术) to show how clothes will fit. It was founded by a person named Salvador Nissi Vilcovsky who was from California. There is a little device (装置) like a computer behind the mirror. First, we should store kinds of clothes including colors and patterns in the mirror. Then, when the customers stand in front of the mirror, the shop assistant only uses hand gestures. Through the gestures, there will be different kinds of pictures in the mirror. The pictures show the right customer in different clothes without any changing. The shop assistant can change different colors, patterns and sizes, and the smart mirror will remember top two best choices, so the customer can compare and contrast. It also lets people see clothes from different angles (角度) without straining (用力拉) their neck or using a wall of mirrors. In 2014, the technology was introduced into Neiman Marcus stores in San Francisco, and later, Texas. It was widely welcomed by the shop owners and the customers. Maybe, we can see one of these interactive mirrors in a shop in China in the near future. 

Do you like watching TV or playing computer games? How long do you use your phone a day? We call the time we spend on TV, computers and mobile phones" screen time".

In a study(研究) in Australia, scientists (科学家) ask 577,000 children how much time they spend on screens, schoolwork and sports every day. They find about 68% of them spend more than(超过) two hours on screens.

Two hours of screen time a day is bad for children's health. The study shows harm starts after 75 minutes of screen time for girls and 105 minutes for boys. Why is that? That's because the study shows that boys take more exercise than girls." In our study, 24% of boys spend an hour a day getting exercise, but only 14% of girls do that," Dr Khan said.

So it is important for children to balance(平衡) their time. Tom Hindhaugh has a" three- time" system for his son Patrick. That is a" go time" for schoolwork,a" slow time" to play computer games or talk with friends on the Internet, and a" green time" for getting exercise." We need to get children to do more exercise. They can walk, ride a bike or play football," he said." Anyway, Patrick is very happy and healthy."
