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.

    A new report from the International Bar Association (IBA) suggests machines will mostly likely replace humans in a growing number of occupations. One of the authors of the report, Gerlind Wisskirchen, believes that governments need to introduce human quotas（配额）in some sectors in order to protect jobs.

    The report suggests that the jobs at risk are common ones, such as accountants and lawyers. Financial services are more at risk than legal roles though, as algorithms（计算机程序）are easier for a computer to solve when compared to keeping client relationships and making new laws. Simple physical work is also in the firing line, the authors mention.

    As the world population heads toward 7 to 10 billion, futurist Morris Miselowski says, “I am not sure that this nine-to-five, Monday to Friday work as we understand it, will continue for many of us for the next couple of decades.” He forecasts that the biggest changes will be a shift（转变）away from the traditional work time..

“Artificial intelligence (AI)（人工智能）… and all sorts of new technologies are just about to happen; all of that's going to change where, how and when we do work.”

Ms Wissfikirchen was surprised by how far-reaching the effects of automation（自动化）are.

     “Even though automation began 30 years ago in the blue-collar sector, the new development of artificial intelligence and robotics affects not just the blue-collar sector, but the white-collar sector,” said Ms Wisskirchen.

    Toby Walsh, professor of Artificial Intelligence at UNSW, said there was a ray of hope when it came to technology and the future of jobs.

“It's always good to remember that although technology will take jobs away as they raise in this report, there will also be new jobs created by technology,” he said. “In fact if we look at the history of technology since the Industrial Revolution, more jobs have been created than destroyed.”

    What would you say if we told you that you could learn to speak a new language in only 7 days? Pretty unbelievable right? But how could it be? To find out,we spoke to David-one of our brave Babbel learners—to see how the Babbel app successfully got him speaking Norwegian(挪威语)in just one week.

How much time did you learn each day?

    I didn't need to give my entire life over to learning Norwegian. Each Babbel lesson takes only 15 minutes, and I set myself the achievable aim of finishing three Babbel lessons daily.This took only 45minutes each day.

How did the Babbel app help you learn so quickly?

    The Babbel app has a course plan for beginners that taught me how to make sentences in Norwegian within the first few days. Then I was able to personalize my learning by selecting single-topic lessons on eating, drinking, music, culture, traveling and so on. This allowed me to quickly enlarge my vocabulary!

    This way of learning kept me highly active,and made sure I wasn't bored to tears with grammar practice that we all remember from school!

    “After 7 days I was able to introduce myself in Norwegian,talk about my hobbies and interests, and most importantly,communicating with a native Norwegian speaker in a real conversation and I could even play a joke or two!”

    Would you introduce this app to others?

    Certainly! Babbel has 14 languages to choose from so if you're thinking about brushing up on your German for a business trip, or learning a bit of Portuguese (葡萄牙语) for next year's summer vacation, you'll be happy to hear that you only need an app, 7 days of learning to get you conversational.

For some people, music is no fun at all. About four percent of the population is what scientists call "amusic". People who are amusic are born without the ability to recognize or reproduce musical notes (音调). Amusic people often cannot tell the difference between two-songs. Amusics can only hear the difference between two notes if they are far apart on the musical scale.

As a result, songs sound like noise to an amusic. Many amusics compare the sound of music to pieces of metal hitting each other. Life can be hard for amusics. Their ability to enjoy music sets them apart from others. It can be difficult for other people to identify with their condition. In fact, most people cannot begin to grasp what it feels like to be amusic. Just going to a restaurant or a shopping mall can be uncomfortable or even painful. That is why many amusics intentionally（故意地）stay away from places where there is music. However, this can result in withdrawal and social isolation. "I used to hate parties," says Margaret, a seventy-year-old woman who only recently discovered that she was amusic. By studying people like Margaret, scientists arc finally learning bow to identify this unusual condition.

    Scientists say that the brains of amusics are different from the brains of people who can appreciate music. The difference is complex, and it doesn't involve defective hearing. Amusics can understand other nonmusical sounds well. They also have no problems understanding ordinary speech. Scientists compare amusics to people who just can't sec certain colors.

Many amusics are happy when their condition is finally diagnosed. For years. Margaret felt embarrassed about her problem with music. Now she knows that she is not alone. There is a name for her condition. That makes it easier for her to explain. "When people invite me to a concert, I just say, 'No thanks. I'm amusic,'" says Margaret. "I just wish I had learned to say that when I was seventeen and not seventy."

    When my family moved to the United States from Colombia, I was 9 years old and knew little about English. As time passed, teachers finally knew all of their students and slowly everyone began to head inside, except for me. No one called out my name, and no one seemed to know I existed. I spent the next month in my new classroom quietly. I felt a wave of fear, loneliness and sadness came over me.

    It turned out the school administration never cared that I didn't speak English, but something else was teaching me English. Every morning when my aunt drove me to school and picked me up, she always had 106.7 Light FM on. It was this station that introduced my young ears to the English sounds of R&B, soul, jazz and much more.

Because of Sabrina the Teenage Witch, I learned the difference between "witch" and "which". While watching the TV show South Park, I was attracted by the funny characters. I related "You bastards!” to anger and saved it in my mental word bank. In fact, thanks to pop culture, the world of English became not so hard to me while it was being turned down at school.

    I also learned how to express my emotions thanks to pop culture. One day at school, we were taking a math quiz and the whole class was quiet. Suddenly, the tip of my pencil broke and I yelled, “You bastards!" Everyone held their breath in surprise and I laughed to myself because something at that moment told me I had just learned my first bad word in English.

    Four months passed before the school placed me into an ESL program. By this time, I was speaking broken English and making myself understood. Finally, I learned how to speak and write English at a more advanced level, and I owe it all to pop culture.

    It's difficult to know the exact answer to whether babies dream and what they dream about. However, sleep experts have shown that newborns dream the most in the first two weeks after birth. Babies spend most of their sleeping time in REM(rapid eye movement) stage. As dreaming takes place in a light state of sleep, newborns tend to wake up due to noises, movements and other factors. When dreaming, newborns make a few noises and their eyes move. They may move around the sides or up and down. They may laugh, scream, or cry during the REM sleep. Also, their facial muscles, hands, and legs move, due to which they may wake up. So wrapping a baby in swaddling(裹紧的) clothes can keep the baby's body from moving and help them sleep better. As babies grow, their body movement decreases when dreaming.

    Studies say that the brain activity associated with dreaming is essential for the babies' mental development. During the REM stage, the flow of blood to the brain increases. As a result, certain nerve proteins are produced, which are the building units of the brain. Babies get stimulation from what they see, hear, or feel. The brain processes the information acquired while awake, and stores what is essential to the individual. A study concludes that babies learned while they were dreaming.

    What's the time for babies to start dreaming? Researchers say that before birth, babies start experiencing REM sleep around week 25, and so they may start dreaming at the point. On the contrary, some psychologists believe that children start having dreams when they are about 5 years old. At that age, they start becoming aware of themselves and begin to understand the things around them, which is what dreams are actually made of.
