The private automobile (私家车）has long played an important role in the United States. In fact, it has become a necessary and important part of the American way of life. In 1986, sixty-nine percent of American families owned at least one car, and thirty-eight percent had more than one. By giving workers rapid transportation, the automobile has freed them from having to live near their place of work. This has encouraged the growth of the cities, but it has also led to traffic problems.

    For farm families the automobile is very helpful. It has made it possible for them to travel to town very often for business and for pleasure, and also to transport their children to distant schools.

    Family life has been affected（影响）in various ways. The car helps to keep families together when it is used for picnics, outings, and other shared experiences. However, when teenage children have the use of the car, their parents can't keep an eye on them. There is a great danger if the driver has been drinking alcohol or taking drugs, or showing off by speeding or breaking down traffic laws. Mothers of victims（受害者）of such accidents have formed an organization called MADD (Mothers Against Drunk Driving). These women want to prevent further tragedies (悲剧）. They have worked to encourage the government to limit the youngest drinking age. Students have formed a similar organization, SADD (Students Against Drunk Driving) and are spreading the same message among their friends.

    For many Americans the automobile is a necessity. But for some, it is also a mark of social position and for young people, a sign of becoming an adult. Altogether, cars mean very much to Americans.

    My family lived in a motel for two years. Like most families living there, we stayed in a two- bedroom suite. We were living from paycheck to paycheck, so when Christmas approached, we didn't know if we could be able to purchase gifts for our children.

    A few days before Christmas someone dropped off presents for all the kids that lived in the motel. It brought so much joy to all the children, most of whom knew that they wouldn't be receiving anything.

Five years ago, we moved out of the motel. After that, my husband and I were working hard at the Joe's Crab Shack to support our family. A few days before Christmas, I was working a “big top” and a single table. The man at my table could see that the large table was taking most of my time, but I was very patient and friendly. Between drinks and food I was able to chat with him about his family and mine. He left me $10, then walked out. About 10 minutes later, I turned around and there he was again. He gave me a hug, and put something in the side of my coat, telling me “Have a Merry Christmas”. I reached into my coat and pulled out $800.

    I was so moved by his generosity that I burst into tears. He had given me more than enough money to help my family catch up on our bills. After discussing what we should do with the money we had left over, we decided to buy presents for the families living at the motel, so we could pass on the blessing that we had received. Since then, it has been a tradition for us to give Christmas gift to the families in need.

    Last year we were able to give presents each of the 80 children at a school in our community, and throw a Christmas party for them. This year our goal is to add at least 20 children.

    After the examination, the doctor told my parents my sight would get worse and that I would lose my sight finally. On the way home from hospital, no one said a word. One day, would I only imagine the scenery beyond the glass rather than see it?

    That September, I entered middle school. Most nights I had homework that included an armful of books to read. To keep up with other children, I took great trouble to finish the task. With my nose a couple of inches from the page, I was tired easily. What's worse, after I had read several pages on my own, the words slipped off the page into inky pools.

    However, then I did not have audio books and electric devices like kids do now. Instead, Mum volunteered to read out loud. Mum worked part-time, cleaned the house, cooked and spent time with Grandma. In spite of being so busy, she showed up in my room like clockwork. She put on her reading glasses. Mum always thought those glasses made her look old. To me, she looked like a teacher.

    In my room, Mum's voice raced with the ticking of the clock. Being forced to focus on listening, I found a way to keep my marks up and compete with the other kids. When the teacher asked a question, I raised my hand with confidence. Teachers praised me for having a good memory. Reading removed my fear for my failing sight, reading also made me curious about other people's challenges and how they managed. Though I could not use my eyes to fix on each passage, my mind lit up with every new book.

    True to what the doctor said, the worst came, but thanks to Mum, my sense of hearing now allows me to “see”. This was the most precious gift from a mother to her child.

    Teenagers in America know that they'll possibly need technical skills to find good jobs, but a new survey reveals that interest in technology-related careers may be decreasing.

The percentage of boys aged 13 to 17 who are interested in science, technology, engineering and math —or STEM —careers dropped from 36 percent in 2017 to 24 percent this year, according to a survey by Junior Achievement USA. The amount of girls interested in STEM careers stayed unchanged at II percent.

    But the 1, 000 survey participants still named technology as one of two key skills that will be necessary to prepare them for their future careers.

    "Kids don' t understand how technology can be applied to careers in addition to computers, and maybe robotics, "said Tammera L. Holmes, president of aviation consulting firm AeroStar Consulting （航空资询公司）.“That's all they know, so they can't really translate that interest to career pathways."

    When Holmes was in high school, her mom sent her to an event that featured (以......为专题)the pilots from World War II. One of the pilots took her for a ride and let her take the wheel immediately that was the career for me." she said.

    Women remain outnumbered(超过) by men in fields like technology. For people working to increase the number of women in these areas, the lack of growth in girls interest in STEM careers is concerning.

    Teenage girls are more interested than their male classmates in running after careers in which they can help others, said Ed Grocholski from Junior Achievement. Even with all the programs aimed at increasing girls' interest in STEM, "I don't think we really talk that much about how we improve people's lives through STEM," Grocholski said.

    Society needs to do better at making those connections for kids, said Katherine Latham, founder of an engineering firm. She used civil engineering as an example of a career that will continue to be important.

    However, the fact that students know they will need tech skills in their future careers is encouraging.

    The second skill they said they need is relationship-building.

    "That's going to be the new type of engineers," Latham said.

    A while back I caught a news report on something called -couch surfing‖ and the network of trusting souls who make this phenomenon possible. They offer to put up travelers free of charge and help them on their ways. At first, it sounded unbelievable. I mean, inviting strangers into one's home for one or two nights? Give me a break.

    However, I was intrigued. I decided to investigate. The only way to truly learn about this phenomenon was to dive in. So I planned a trip to Finland, a country I've always wanted to explore. I would couch surf at every stop there.

    If ever any anxiety existed when stepping into the unknown, it disappeared when my first host met me at the train station. Ari looked like my idea of a typical Finn: tall and blue-eyed. Finns were also supposed to be famously reserved (寡言少语的). Ari was anything but. He was a live wire, giving me an enthusiastic welcome and hiking with me to his apartment, where he showed me the sleeper sofa, served me tea, and engaged me in warm conversations. He also handed me a key to come and go as I pleased.

    If this was what couch surfing was all about－trust and friendship－then I had gotten off to a good start. As I boarded my next train to continue my journey, I began to think about this couch-surfing idea. What urged these people to open their homes to strangers? I concluded that there was a desire to lend a hand to like-minded folks who might enrich their own lives.

    Seven cities in 14 days. Seven hosts. Seven new friends. If couch surfing taught me anything, it's this: Most people are good and generous. Where will couch surfing take me next? Who knows? But I can't wait to find out.

In 1835, William Talbot finally succeeded in producing a photograph of his country house. He declared that his was the first house ever known to have drawn its own picture. The drawing was formed "by the action of light upon sensitive paper." Photography offered nature a "pencil" to paint herself through optical （光学的） and chemical means alone.

By the mid-nineteenth century, people no longer needed to hire a draftsman to draw detailed images because the process could be completed instantly with a camera. Advocates for the technology stated that not only was it more precise than the human hand-it was faster and cheaper.

The removal of human fallibility in the creating process was one of photography's biggest selling points, but this also started debates about the new medium's implications for visual culture. Could images made largely by a machine be considered art? If so, where did human creativity, fit in this process?

As the twenty-first century becomes increasingly automated （自动化的）, more and more people attempt to identify where human agency exists in the technologically driven world. Images generated with artificial intelligence by companies like OpenAI are stimulating questions like those that emerged with the coming of the photograph. By typing a sentence, users can generate "new" images composed from images collected across the internet. The result has been a flood of Al-generated images in places that are previously unique to human authors. Painting competitions, commercial graphic design and the fashion of portraiture（肖像） have all since collided with the technology in troubling ways.

The fine arts were thought to be a final hold-out of human creativity, but the surprisingly high quality of Al-generated images is producing deeper questions about the nature of originality. If the history of photography tells us anything, it's that the debate won't be settled quickly; straightforwardly or by the institutions we typically associate with cultural gate-keeping.
