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.

    Charlie and his family don't always live in their house. Sometimes they live in a houseboat. There are 4 rooms in the bottom of the boat. One of them is his parents' bedroom. Another one is his bedroom. Then there is a kitchen and a bathroom. Charlie's bedroom is small, but he likes it very much. It has a small window. He doesn't open it because it's under the water. When the boat is in the water, Charlie can look out of his window and see many fish under the water. Once he saw an old car under the water. He thought it was funny to see the fish swim through the car windows.

    In the school year, Charlie's family keep their boat on the bank (岸) of the lake. In summer Charlie and his family often take their boat out to the middle of the lake. They stay on the lake for a few weeks. Then they go fishing for their food. Charlie's mother grows vegetables in pots on the boat, so they also have vegetables to eat. When it is very hot, they jump into the water and go swimming. Charlie thinks a houseboat is the best place to live in.

Dong Lina grew up in a farmer's family in Dalian, Liaoning. She couldn't see clearly when she was a baby. She couldn't see anything when she was only ten years old.

Dong went to a special school for people who can't see or hear. After that, she learned tuina and then found a job. One of her teachers said tuina was her only way out. But Dong didn't think so.

In 2006, 22-year-old Dong took part in a radio host (主持人) programme. Soon she fell in love with broadcasting. It was really difficult for her to learn that, but Dong tried her best and practiced every day. A year later, she got good grades (等级) in the Mandarin Proficiency Test. She could work as a radio host!

In 2015, Dong became the host of a radio programme. And in the same year, she went to learn radio and TV broadcasting in Communication University of China. She also worked as a part-time teacher in her free time.

Last July, Dong finished her study in the university.

She's the first visually impaired master (硕士) of broadcasting in China. She says, "We should always have dreams and work hard for them."

"Oh, dear! It's not good to eat only a 4 for breakfast. You5 to drink some milk too! It's important to eat well. "

Hearing6 words, Cindy laughs（大笑）. She says, "Oh, you mistake(错认）Pisa for pizza（披萨）, Grandma! Here, the Leaning Tower of Pisa(比萨斜塔）is a building(建筑）, not something to 7 ! "

"Haha! That's funny!"Grandma also laughs, "Dear, be sure to take some 8 of it. I'm going to send(发送） them to my friends. Have9 ! Bye!"
