We were on the way from Hutchinson to Chicago for a short spring break. For many years I had wanted to take my family on the train. We all had been to Chicago four years ago, and the kids loved it. Chicago is one of my favorite cities, too, so the thought struck me again last fall to ride the train to Chicago. Of course, flying would have been faster. But I don't think flying is easier, especially these days, with all the security and waiting in lines at airports.

    Though we were tired in the middle of the night, the kids got on the train with the exhilaration of this adventure. “We're moving,” my son William shouted happily with big eyes as the train began to pull away from the Hutchinson station.

    I removed my shoes and lay down to try to finish my night's sleep. The sleeper car would have better enabled that, but the ordinary train seats were not too bad. An airline flight is a more miserable experience for me: not enough room, two hours of pain with my knees almost touching my chin, the hard seatback in front cracking my kneecaps (膝盖) with every move of the body planted in front of me. On the train I could almost outstretch all of my 6-foot-2-plus body in the generous legroom.

    The journey didn't feel at all as long as it was. We all found the train ride a joy. The car ride would have felt every minute of 13 hours. But on the train you are free to walk around, sit in the observation carriage for a while and enjoy the scenery out the windows, have a nice meal in the dining car, read a book, or play a board game.

    In short, the train is all about enjoying the trip, which isn't something I do so much when traveling by airline or by car, when the trip seems more of a mission (任务) to get there than an experience to enjoy along the way.

    Chicago offers much to do for a family. This time, getting there was half the fun.

    Dr. Sasaki knew the first-night effect probably has something to do with how humans evolved.

    The puzzle was what benefit would be gained from it when performance might be affected the following day. She also knew from previous work conducted on birds and dolphins that these animals put half of their brains to sleep at a time so that they can rest while remaining alert enough to avoid predators (捕食者). This led her to wonder if people might be doing the same thing. To take a closer look, her team studied 35 healthy people as they slept in the unfamiliar environment of the university's Department of Psychological Sciences. The participants each slept in the department for two nights and were carefully monitored with techniques that looked at the activity of their brains. Dr. Sasaki found, as expected, the participants slept less well on their first night than they did on their second, taking more than twice as long to fall asleep and sleeping less overall. During deep sleep, the participants' brains behaved in a similar manner seen in birds and dolphins. On the first night only, the left hemispheres (半球) of their brains did not sleep nearly as deeply as their right hemispheres did.

    Curious if the left hemispheres were indeed remaining awake to process information detected in the surrounding environment, Dr. Sasaki re-ran the experiment while presenting the sleeping participants with a mix of regularly timed beeps (蜂鸣声) of the same tone and irregular beeps of a different tone during the night. She worked out that, if the left hemisphere was staying alert to keep guard in a strange environment, then it would react to the irregular beeps by stirring people from sleep and would ignore the regularly timed ones. This is precisely what she found.

    It's a sadness shared by many business start-ups: why did my company fail, while so many others seem to be profiting from the “golden age of entrepreneurship (创业精神）”？

    Some people argue that opportunities and good fortune are the secrets to success. But Innovation Works CEO Kaifu Lee believes that entrepreneurs need to have certain qualities to help them face the difficulties of starting a business. At a recent LinkedIn conference, Lee mentioned some of these qualities.

    “Even though we're now in a golden period for innovation and start-ups, not everyone is meant to be an entrepre- neur. Entrepreneurs share the same qualities — they are confident, communicative and focused. They don't fear losing, and they are good at learning,”he said.

    Lee explained that he often meets young people who are irresolute about setting up a business.“ If that's the case for you then don't do so,” he said at the conference. The bottom line, he said, is that entrepreneurs should be determined and passionate.

    Passion is vital to entrepreneurs since it typically relates to self-motivation, according to Li Jun, 26, founder of Wuhan Lushenglin Plant Wall Co Ltd. “Entrepreneurs often need to work around the clock. It's easier for people to put up with the difficult schedule if they're passionate about what they're doing,” he said.

    Entrepreneurs are also generally thought of as risk-takers. But Yu Xiuhong, general secretary of the Bright China foundation, warns that young entrepreneurs should not take too many risks. “Successful entrepreneurs rarely take risks blindly or jump at opportunities others avoid. Before launching a business, it's advisable to do market research, evaluate yourself and your opponents,” she said.

    Also she advises that young people thoroughly calculate their expenses in advance. Take Li Dongjin as an example, 35-year-old long-term entrepreneur disappeared a week ago after his O2O car washing company failed disastrously. He had gotten an initial investment of 5 million yuan but wasted it all on allowance and publicity.

    John is a mechanic, but he lost his job a few months ago. He has good heart, but always feared applying for a new job.

    One day, he gathered up all his strength and decided to attend a job interview. His appointment was at 10 am and it was already 8:30. While waiting for a bus to the office where he was supposed to be interviewed, he saw an elderly man wildly kicking the tyre(轮胎) of his car. Obviously there was something wrong with the car. John immediately went up to lend him a hand. When John finished working on the car, the old man asked him how much he should pay for the service. John said there was no need to pay him; he just helped someone in need, and he had to rush for an interview. Then the old man said, "Well, I could take you to the office for your interview. It's the least I could do. Please. I insist." John agreed.

    Upon arrival, John found a long line of applications waiting to be interviewed. John still had some grease(油脂) on him after the car repair, but he did not have much time to wash it off or have a change of shirt. One by one, the applicants left the interviewer's office with disappointed look on their faces. Finally his name was called. The interviewer was sitting on a large chair facing the office window. Rocking the chair back and forth, he asked, "Do you really need to be interviewed?" John's heart sank. "With the way I look now, how could I possibly pass this interview?" he thought to himself.

    Then the interviewer turned the chair and to John's surprise, it was the old man he helped earlier in the morning. It turned out he was the General Manager of the company.

    "Sorry I had to keep you waiting, but I was pretty sure I made the right decision to have you as part of our workforce before you even stepped into the office. I just know you'd be a trustworthy worker. Congratulations!" John sat down and they shared a cup of well-deserved coffee as he landed himself a new job.

    Paris is the city of dreams; the city of love. If you are thinking of heading to Paris for a study period, then perhaps a little reality check is in order. But my experience was a romantic one.

    I paved my path to Paris through an exchange program. On arrival in Paris, I was constantly reminded of the official processes I was required to complete — forms to be filled in, meetings to attend, the list seemed endless. Perhaps it was due to my well organizational habit, but somehow this endless list of to do's was completed in little more than a week.

    Then the real work began. Once classes were underway, I found myself volunteering to do oral presentations and assignments first, rather than last. This method turned out to be very helpful.

    Once I had finished class for the week, I had an ever-increasing list of museums to visit, neighborhoods to explore, cafés to sit in, and parks to run around. Read as many books about Paris as you can. Talk to as many locals and other foreigners living there as you can. The one thing that reading a book or talking to someone cannot do is to provide you with the experience of wandering Paris on foot. I discovered some of my favorite places in Paris by wandering. The people watching, the sounds of the city, the colors as the seasons change, they all add to the ecstasy that is experiencing Paris as an exchange student.

    After spending five months wandering through the charming neighborhoods, I fell in love with the atmosphere that came out from every open door, and with every spoken word. There is something comforting about walking to the market each Sunday to be faced with the beautiful display of fruits, vegetables and dairy products. There is warmth in saying bonjour to the man across the hall.

    On my last day in Paris, I confidently said, “Bonjour Monsieur,” as I passed the little store down the street. I guess no matter how hard I tried I was always going to be an outsider, a tourist. The best part about going on exchange in Paris is falling in love with the city in your own unique way. Everyone's experience of Paris is different. I know mine is unique and special to me, my own little pieces of Paris.

    Hip-hop dancing(街舞) is popular with many young people today. They like it because they can invent their own moves. They use this dance to show their love for life. It also shows that they are not afraid of problems.

    Hip-hop dancing has a history of more than 20 years. It first began in the 1980s in the US. In early times, it was seen in New York and Los Angeles. At that time, many young black people often danced to the music in the streets. They used their legs, arms, heads and even shoulders to dance. Many young people still use most of these moves today.

    Hip-hop dancing became popular all over the world because of the 1983 movie Flash dance. Some people performed Hip-hop dancing in the movie. People enjoyed their performance. They began to dance like them. Then it became popular. There are two kinds of Hip-hop dancing: new school and old school. More and more young people are learning Hip-hop dancing. People believe that it is a good way to exercise their bodies, and that it is good for their health.
