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.

    Do you know how it is when you see someone yawn and you start yawning too? Or how hard it is to be among people laughing and not laugh yourself? Well, apparently it's because we have mirror neurons (神经元）in our brains.

    Put simply, the existence of mirror neurons suggests that every time we see someone else do something, our brains imitate (模仿)it，whether or not we actually perform the same action. This explains a great deal about how we learn to smile, talk, walk, dance or play sports. But the idea goes further： mirror neurons not only appear to explain physical actions _y they also tell us that there is a biological basis for the way we understand other people.

    Mirror neurons can undoubtedly be found all over our brains, but especially in the areas which relate to our ability to use languages, and to understand how other people feel. Researchers have found that mirror neurons relate strongly to language. A group of researchers discovered that if they gave people sentences to listen to ( for example ："The hand took hold of the ball" ) , the same mirror neurons were triggered as when the action was actually performed (in this example, actually taking hold of a ball).

    Any problems with mirror neurons may well result in problems with behavior. Much researeh suggests that people with social and behavioral problems have mirror neurons which are not fully functioning. However, it is not yet known exactly how these discoveries might help find treatments for social disorders.

    Research into mirror neurons seems to provide us with ever more information concerning how humans behave and interact(互动）.Indeed, it may turn out to be the equivalent (相等物）for ncurosciencc of what Einstein's theory of relativity was for physics. And the next time you feel the urge to cough in the cinema when someone else does--well，perhaps you'll understand why.

    Books are for reading, but man must bring to their reading a desire to learn and a power of absorbing. Reading should be active, not passive.

    When students first go to a library, they may be at a loss as to what to read of all the different subjects. Well, Bacon tells you to “look at weak places in your armor(盔甲)”, and shows you how to fill up the blanks in your knowledge. On the other hand, it is no good just trying to fill your mind with knowledge. Knowledge in itself is often useless. A mind filled with too much knowledge is like a room too full of furniture; a man cannot walk about freely in it, and look out of the windows. It is much better to concentrate on a few subjects which interest you and to deal lightly with the others than to march heavily through the whole range(范围) of learning, like a silly tourist going through a museum and not missing a single object. If you try to master every subject you may become very wise, but you will be very lonely and you will probably lose all your friends. So you must learn to pick and choose, and you must also learn to look here and there in a library like a camel eating grass on the grassland. If you watch it eating, you will see that although he is supposed to be one of the most stupid animals in the world, he has at least one of the qualities of the cultured man, the power to pick and choose. A student looking for mental food in a library should take the camel as his model.

    There is an old style out there of young girls talking endlessly on the phone with one another. It's an idea that is far from untrue in many families. I remember being a twelve-year-old and spending some quality time on the phone with my girl-friends, even though we'd seen each other at school. I didn't really have anything to talk about, I guess, but I think I was just happy to have someone else to talk to and that someone wanted to talk to me.

    We call this phenomenon (现象) of girls going on forever over the regular phone “girl talk”. And these days, girl talk has spread far beyond the old phone-teens communicate with each other pretty much nonstop through cell phone, texting，online chat. Is girl talk a good thing? According to experts, it can be-in limited quantities.

    Girl talk has its place. But too much of it, especially the kind during which problems are talked about endlessly can be not such a good thing. Psychologists (心理学家) think that too much of that kind of talking can lead to emotional problems such as depression (沮丧) and anxiety. Girls, much more so than boys, will always think of a problem and get worried, making the problem worse other than solving it. The best way is to try to guide the conversation toward something positive, or to do something about the problem rather than sit around and chat about it endlessly.

    Shyness May Be Partly Inherited(遗传)

    About 92 million Americans are shy, and according to recent research about half of them inherited the trait.

    The studies were discussed at the American Psychological Convention.

    One study, by Harvard University, was of babies 21- 48 months old. It concluded that these babies had a high heart rate when shown unfamiliar people or different toys.

    Although shyness is not new, it has only recently become of interest to researchers. The first study on the genetic connection was in 1979.

    According to Warren Jones of the University of Tulsa, social relations these days are more complex. "With less ritual(仪式) and more complex situations," he said, "shyness is a national concern."

    Not all shy people are anxious and fearful, according to another study. Evidence shows that only half of shy people are tense, worried, and fearful in social situations.

    Many men use shyness as an excuse for failing in social situations, according to C.R. Snyder of the University of Kansas. "This is not true of females. Perhaps, American men are pressured to be assertive(自信的) and successful. So they would rather say they're shy than admit they're incompetent."

    Shy people may do very well socially after the first meeting with someone. In fact, shy people tend to be more stable.

    The psychologists said shyness seems to be cultural. Japan has the highest rating. China and Israel have the lowest rating. The United States rated in the middle.
