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.

High school does not encourage students to know about the new things in life, but college sets the stage for it. I myself went through this 1process (过程) and found something that has changed my experience at college for the better: I discovered ASL﹣American Sign Language.

I never felt it necessary to learn any sign language before. All of my family members can hear, and so are all my friends. The  2 language was enough. Little by little, I discovered my  3 for ASL.

The 4began during my first week at college. I watched it carefully when the ASL club performed their translation of a song. Both the hand movements and the idea of communicating without speaking attracted me. What I saw was completely different from anything I had experienced in the past. This new form of communication just made me want more.

After that, feeling the need to 5 further, I decided to join one of ASL clubs. I only learned how to express my feelings 6 my hands about the letters that day. Although my process was 7, I wasn't disappointed about it. I then tried my best to take part in those club's meetings and learned all I could.

The following term, I decided to be a member of an ASL class. The professor was deaf and any talking wasn't 8. I soon realized that silence was not unpleasant. 9, if there had been any talking, it would have caused to learn less. Now, I enjoy the silence and the 10 way of communication.

    When I just moved to Los Angeles（洛杉矶）, I didn't have a car.{#blank#}1{#/blank#}, but I wanted to prove（证明）them wrong.

    I asked my neighbor, Mrs. White, to take me to the bus station in the center of the city, so I could try taking the bus home.{#blank#}2{#/blank#}. When I got there, I went inside and got a bus timetable（时刻表）. I looked at the map and worked out that I needed to take three buses to get home.

    I bought the tickets and went outside to wait at the bus stop for the Number 8 bus. {#blank#}3{#/blank#}. I gave my ticket to the bus driver and took a seat. At the right stop I got off. {#blank#}4{#/blank#}. I waited and waited. A man was also waiting for the same bus. He said that it wasn't unusual for the bus to be late. Half an hour later, it finally came. To make the matter worse, the third bus broke down halfway and the driver had to fix it. {#blank#}5{#/blank#}. So when I finally got home, I was very tired. Maybe getting a car in Los Angeles wasn't such a bad idea!

Mother Tongue (语言)

    My name is Jiniku but everyone calls me Joey, including my parents. My father is American but my mother is not. My mother grew up in a country whose name I cannot pronounce correctly. She was educated in French and Latin, Spanish and German.

    My mother wrote all day, but never showed anyone what she wrote. She had notebooks she would write in, and a typewriter to straighten out (整理) the final copy.

    When she had typed (打字) pages, she put them in a box. This box was deep under the bed that she and my father shared.

    There were only two words that she ever said in the real voice, with her real accent (口音), real tongue. I heard her say them only three times in her life. She taught them to me one night as I lay on her legs, sweating (出汗) with fever.

    "Jiniku," she said in a low voice. "Jiniku." I focused (集 中) on her voice through my fever, realizing that something had changed. She was speaking from a part of her that she had not opened for a long time. She took my hand, and placed my palm (掌心) over her heart. "Juriszu." She stared out the window. There was a long silence. I could feel her heartbeat, which was calmer and slower than my own. "My name," she said at last, speaking once more in English, "means „dark ocean (海洋).‟ And you, Jiniku, my baby, yours means „life.‟" She looked out the window again. "„Ji‟ is the word for a happy birth. One where everyone lives and there is little pain. „Ni‟ is a tree that had its roots (根) spread far and whose branches (树枝) shelter (庇护) all. „Ku‟ is spirit. You have this all-encompassing (包罗万象的) life." She placed her hand on my heart. "The first and last letters of our names are the same," she said. "Don‟t forget that, Jiniku."
