Haiyan is 7 years old. Her parents gave her an iPad as a gift for her birthday. A month later，her eyesight（视力）dropped to 300 degrees. This is serious for such a young child.

    Many children in China are facing the same problem: iPad using is bringing problems to their eyesight. The problem is so common that newspapers even call the iPad the "No. 1 killer of children's eyesight!"

    "There are about 30 shortsighted children coming every day, "said Hu Dali, an eye doctor at Guiyang Aier Eye Hospital. "Half of those children have poor eyesight because they have played with phones and iPads for too long. "

    Doctors and scientists say children's vision（视觉）is not yet fully developed and their eyes get tired more easily. The screen of an iPad uses very bright（明亮的）LED backlight. If children look at an iPad screen for a long time, their eyes do not have time to rest. This will make their eyesight worse over time.

    Doctors advise that users should hold their iPads between 40-60 centimeters（厘米）away from them. The brightness of the screen should be comfortable for children. Parents should also stop their children from using an iPad for more than one hour every day.

    Do you know something about the holiday camps in Hong Kong? In the past, the students in Hong Kong usually join an English holiday camp in their holidays. And their parents didn't go with them, though they were very young.

    Now they still enjoy joining many kinds of holiday camps without their parents. Many parents let their children join some kinds of holiday camps in order to learn some useful knowledge in the life and also learn some knowledge about living skills, science, reading, writing and so on. The most important thing for the children to join the holiday camps is to learn to look after themselves.

    Holiday camps in Hong Kong are not so expensive. Most families can afford to sent their children there for study or for making their bodies strong.

    It is said that students in Hong Kong have much knowledge about many things. Perhaps it has something to do with all kinds of holiday camps.

I was walking along a busy road when I noticed a young man standing near the crossing selling toys.1I would hurry past such sellers. But I found this young man was 2, so I stood for some time without crossing the street. I wanted to see how he sold his things.

Soon, a young mother with a little girl came by and the child set 3 eyes on one of the teddy bears. The mother asked the 4 and it was only one dollar. She 5 out a 10­dollar note from her handbag and told the young man that she was giving him 10 dollars and wanted the 6 back. I was wondering how he was going to do it. He told the young mother to put the money in the bag 7 around his neck and take out her change.

I realized that this young man depended on believing people would not cheat him. There was no way for him to know 8 someone took out more than they should have done. I was so 9. I bought a car model from him that I did not need. As I walked down the street, I gave the car model to a kid walking with his father.

I kept thinking that the world would be a better place if we could all learn to 10others more, like the young blind street seller.

27- year- old Pei Haozheng is skilled in creating artworks by using paper. In his eyes, a single piece of paper can make a big difference. He can fold it into anything, from daily objects to ancient people. 

Born in Nanjing, Jiangsu Province, Pei started folding paper when he was a little kid, because paper was cheap and easy to get. At first, he learned folding from his friends and parents, and later he copied the style from books. From cranes to planes, he was fascinated by（着迷于） the magic world made by paper. Every day, he spent hours folding paper. 

In order to improve his folding skills, Pei taught himself through origami（折纸工艺） books. As the number of his works grew, so did the quality. His hard work paid off（得到回报） and then Pei began to create more complex（复杂的） designs. 

Pei won the International Origami Internet Olympiad in 2017, combining the art with Chinese cultural ideas. For the event's final task, he folded an ancient Chinese woman holding a mirror from a piece of hand made xuanzhi, a kind of rice paper. The artwork caught the judges'（裁判的） eye with its special shape and Eastern style. In September2022, Pei even set the Guinness World Record for most origami flowers made from a single piece of paper. 

Although people might be amazed at the complexity of the designs and skills needed to produce the artworks, Pei is always willing to keep trying new artworks. He said, "I get inspiration from Chinese culture and of course, I want to help Chinese culture go global（走向世界）. "
