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.

    Not many years ago, a wealthy and rather strange old man named Johnson lived alone in a village in the south of England. He had made a lot of money in trading with foreign countries. When he was 75, he gave ￡12,000 to the village school to buy land and equipment for a children's playground.

As a result of his kindness, many people came to visit him. Among them was a newspaperman. During their talk, Johnson remarked that he was 75 and expected to live to be 100, and the newspaperman asked him how he managed to be healthy at 75. Johnson had a sense of humor. He liked whisky and drank some each day. "I have an injection (注射) in my neck each evening", he told the newspaperman, thinking of his evening glass of whisky.

The newspaperman did not understand what Johnson meant. In his newspaper he reported that Johnson was 75 and had a daily injection in his neck. Within a week, Johnson received thousands of letters from all over Britain, asking him for the secret of his daily injection.

A man was walking in a forest. He was holding an axe (斧子) in his hand. A little tree stopped him and said, "Please use your axe to 1 those tall trees, my friend. Because of them, the sunlight cannot fall on me, and I have no room at all to spread myself. Without them, I'll be the tallest tree in the forest."

The man 2 to help the little tree. He used his 3 to cut down the trees. Then the little tree had 4 room. The little tree felt happy and said 5 to the man. When the Sun came out, the little tree lost water and it became very 6 . Later when a storm came, the little tree 7 all its leaves and branches. "Oh, poor little tree!" a bird said 8 "You shouldn't ask the man to cut down the trees. The tall trees protected you so that you didn't worry about heat or wind or rain. Time went by and you would 9 . When you get tall and 10 , you can have enough strength to fight against the Sun and the storms. So I don't think you should do that." After hearing the words of the bird, the little tree felt regretful (后悔的).

Our community library decided to offer a painting class. I told my friend Ella, and we both signed up.

On the big day, our first 1 was to paint a white vase of cheerful yellow sunflowers against a blue background.

We were asked to paint our canvas (画布) 2 . It was easy to follow the instructor to move the brush. Although I had never painted before, I could tell I was a 3 . I started thinking about where I would hang my new masterpiece.

Immediately after that, however, I began to run into 4 . The first curved (弯曲的) line of my vase looked perfect, but when I painted the line on the opposite side, my hand slipped (打滑). I tried to 5 that white streak (条痕) with blue paint, but it didn't work.

While I was busy fixing my messy painting, the instructor explained how to paint the sunflower leaves. Things went downhill fast after that. My leaves looked like fat, green caterpillars (毛毛虫). When I failed to clean my paintbrush, I accidentally made the sunflowers green. I felt 6 when I saw how good everyone else's paintings looked.

Ella sweetly praised my sunflowers, perhaps feeling sorry for me. When I said that hers were much better, she looked surprised. "No, they're not. I messed up in at least five places." After a few seconds, she asked, "Want to 7 paintings?"

Until that moment, I had felt only dislike for my painting. And yet for some reason, giving it away felt wrong. It wasn't a perfect painting, but it was mine—the first one I had ever created. I knew Ella must have realized that she felt the same way when she suddenly shook her head and said. "Never mind."

My sunflower painting still hangs directly above my bed. I often look at it. Every time I look at it. I 8 . It always brightens my day and brings warmth to my room. I really like it now.

I took a trip to Shanghai with my mother during the seven-day holiday. It took {#blank#}1{#/blank#} more than two hours to drive to Shanghai from my home in Haimen. Shanghai is a busy and large city. Its population is over 24 {#blank#}2{#/blank#} . That's {#blank#}3{#/blank#}than the population of many other cities in China. 

On the first day, I just {#blank#}4{#/blank#} in the hotel and rested. On the {#blank#}5{#/blank#}day, my mother and I went to Nanjing Road. It is the busiest street in Shanghai. When we got there, there were lots of people. We walked from one shop to {#blank#}6{#/blank#}. I bought two T-shirts and two {#blank#}7{#/blank#} of trousers for the coming summer. The T-shirts and trousers I bought are all white because white is my {#blank#}8{#/blank#} colour. My mother also bought some clothes. On the third day, my mother took me to Shanghai Disney Resort. It was full of people. I took many{#blank#}9{#/blank#} there. I had a good time. 

For the other days, I went to some other interesting places, such as the Oriental Pearl TV Tower, the Huangpu River and the Shanghai International Convention Centre. I didn't forget to {#blank#}10{#/blank#} my homework in the evening. I had a full and happy holiday.
