I remember my mother as a strong woman. She came to America when she was 12—old enough to remember her language, she achieved scores and grades high enough to be admitted to Duke University. With a degree in computer science, she finally became the manager of a company in New York. My mother could give fluent speeches, say “wolves” correctly.

    It was my mother who always stressed the importance of language. From the time I was born, I was read to. I would fall asleep to the sounds of my parents' voices, whether it was my dad's softly accented, or my mother's clear English. The flow of language was unbroken, and whether in Chinese or English, the stream of communication flowed through our house.

    One October morning in sixth grade, after my mother had left to catch the train to the city, I left the house for the bus stop. I was surprised when I saw our car, the door hanging open. As I drew closer, I saw my mother lying on the ground.

    In the hospital, it was hard to believe that the lady who lay before me was my mom. My mother could not remember my name. As the leaves changed colors, it became clear that the stroke had created a wall between my mothers mind and mouth: her mind was not any less dear, but the words she spoke were not what she meant.

    The battle my mother faced taught me the importance of language. Without it, identity does not exist; relationships cannot be formed; stories cannot be told; directions cannot be given, and knowing anything about anyone is impossible. Without language, communication cannot take place. Without language, one cannot express the beauty of a sunset or the kindness of a stranger. The world would pass us by in silence.

    In today's Internet age, the demand for online games continues to grow. Online computer game centers exist in many cities and towns throughout Asia. Facing the pressures of school and life, people turn to the virtual world, expecting a diversion from these problems. Too often, however, they can lead to problems and unhealthy addictions.

    This is most clearly seen in the example of South Korea. The country has the world's highest percentage of high-speed Internet services. It also has a high number of online game players and related problems. In 2013, a young man collapsed and died while playing online games. He had been playing almost nonstop for 86 hours at an Internet cafe. Another young man killed his sister after becoming confused between the online world and real life. A 12-year-old boy stole US $ 16,000 from his father and ran away from home. He did this to continue his obsession with an online game. Such problems, however, don't just happen in South Korea. They are spreading to other parts of Asia, as well.

    What kinds of people develop online game addiction? What does the problem look like? Dr. SueHuei Chen, a clinical psychologist, researches Internet addiction. She discovered some signs of at-risk individuals such as lack friendships and good social skills. Those problem individuals feel it so compulsive to play online games that they could sacrifice things such as school or family. They feel the need to spend more and more time online. And they become upset if anyone tries to limit their online game playing.

    How many problem game players are there? In mainland China, the potential number of problem online gamers is alarming. In 2014, the China Daily reported that China had 13.8 million online game players. Furthermore, it stated that 80 percent of these were under 25 and had signs of addiction. Such numbers point toward a growing problem among Chinese youth.

Make sure to keep control over your online game playing. If you don't control it, it can get control of you.

    As a young girl growing up in the 1930s, I always wanted to fly a plane, but back then it was almost unheard of for a woman to do that. I got a taste of that dream in 2001, when my husband arranged for me to ride in a hot air balloon for my birthday. But the experience turned out to be very dull. Around that time, I told my husband that I wanted to skydive. So when our retirement community announced that they were having an essay competition and the topic was an experience of a lifetime that you wanted to have, I decided to write about my dream.

    In the essay, I wrote about my desire to skydive, stating George Brush Sr. did age 80. Why not me? I was just 84 and in pretty good health. A year went by and I heard nothing. But then at a community party in late April 2009, they announced that l was one of the winners. I just couldn't believe it. Inspired by this, I decided to realize my dream, even though some of my family members and my doctor were against it.

    One June 11, 2009, nearly 40 of my family and friends gathered in the area close to where I would land while I headed up in the airplane. My instructor, Jay, guided me through the experience. The plane was the noisiest one I had ever been in, but I wasn't frightened－I was really just looking forward to the experience. When we reached 13,000 feet, Jay instructed me to throw myself out of the plane. When we first hit the air, the wind was so strong that I could hardly breathe. For a second I thought, “What have I gotten myself into?” But then everything got calmer. We were in a free fall for about a minute before Jay opened the parachute （降落伞）, then we just floated downward for about five minutes. Being up in the clouds and looking at the view below was unlike anything I have ever felt－much better than the hot air balloon. I was just enjoying it.

    Skydiving was really one of the greatest experiences of my life. I hope other people will look at me and realize that you don't stop living just because you are 84 years old. If there's something you want to experience, look into it. If it's something that is possible, make it happen.

    For more than fifty years, a worker was forced to sit on the back of a truck and slowly drop plastic barriers（障碍） to set out lanes（车道）on the Golden Gate Bridge in San Francisco. Every day, their direction changes to control the traffic, meaning an employee had to go through the difficult task every twenty-four hours.

    But a new piece of machinery means the work can be completed in a matter of minutes. A new “zipper truck” has been introduced. The vehicle lays and moves a lane barrier as it drives over the bridge. Last weekend, the bridge was closed so the new safety barrier, designed to reduce the dangers of head-on crashes, could be set up.

    For the longest period in its nearly eighty-year history, the bridge was closed early Saturday to all but walkers, cyclists and buses to set up the barriers on the 1.7-mile bridge. A survivor of a 2008 head-on crash on the bridge spoke Sunday from a wheelchair to help introduce the new barrier, made of steel-clad concrete（铜包混凝土）blocks that can move across the bridge's six lanes to meet traffic needs.

    Gr. Grace Dammann pushed for a safer barrier since becoming unable to walk after the accident. She said she decided to drive near the middle of the bridge, which was called the “suicide（自杀）lane”, because she and her daughter were running late. Brian Clark, who was driving in the opposite direction, had just learned his father had cancer. “He suddenly lost control of the wheel, crossed over and hit my car,” Dammann said.

    She said she and Clark became friends as they persuaded（说服）the government to use the MYM30 million barrier. “I am so thankful,” said Dammann, who came to the ceremony with Clark.

    “Clark and I thank you.”

    "Dreams may be more important than sleep. We all need to dream," some scientists say. Dreams take up about one quarter of our sleeping time. People have several dreams each night. Dreams are like short films. They are usually in colour. Some dreams are like old films. They come to us over and over again. That may be because the dreamer is worrying about something. Dreaming may be a way of trying to find an answer. Some people get new ideas about their work from dreams. They may have been thinking about their work all day. These thoughts can carry over into dreams.
    Sometimes we wake up with a good feeling from a dream. But often we can't remember the dream. Dreams can disappear quickly from memory. Too much dreaming can be harmful. The more we sleep, the longer we dream. The mind is hard at work when we dream. That is why we may have a long sleep and still wake up tired.

    Languages have been coming and going for thousands of years, but in recent times there has been less coming and a lot more going. When the world was still populated by hunter-gatherers, small, tightly knit(联系) groups developed their own patterns of speech, independent of each other. Some language experts believe that 10,000 years ago, when the world had just five to ten million people, they spoke perhaps 12,000 languages between them.

    Soon afterwards, many of those people started settling down to become farmers, and their languages too became more settled and fewer in number. In recent centuries, trade, industrialization, the development of the nation-state and the spread of universal compulsory education, especially globalization and better communications in the past few decades, all have caused many languages to disappear, and dominant languages such as English, Spanish and Chinese are increasingly taking over.

    At present, the world has about 6,800 languages. The distribution of these languages is hugely uneven. The general rule is that mild zones have fewer languages spoken by many people while hot, wet zones have more, often spoken by small numbers. Europe has only around 200 Languages: the Americas about 1,000, Africa 2,400; and Asia and the Pacific perhaps 3,200, of which New Guinea alone accounts for well over 800. The median number(中位数) of speakers is a mere 6,000, which means that half the world's languages are spoken by fewer people than that.

    Now over 400 of the total of 6,800 languages are close to extinction(消亡), with only a few elderly speakers left. None of these seems to have chances of survival.
