Baby girls make their way to dolls as soon as they can crawl, while boys will head for the toy cars,  a study has shown. The findings, the first to show consistent differences in very young babies, suggest there is a biological basis to their preferences.

    Psychologists Dr Brenda Todd from City University London carried out an experiment involving 90 babies aged nine months to 36 months. They were allowed to choose from seven toys. Some were boys' toys - a car, a digger, a ball and a blue teddy.  The rest were girls' toys: a pink teddy, a doll and a cooking set. They were placed a meter away from the toys, and could pick whichever toy they liked. Their choice and the amount of time they spent playing with each toy were recorded.

    Of the youngest children (nine to 14 months), girls spent much longer playing with the doll than boys, and boys spent much more time with the car and ball than the girls did. Among the two-and three-year-olds, girls spent 50 percent of the time playing with the doll while only two boys briefly touched it. The boys spent almost 90 percent of their time playing with cars, which the girls barely touched. There was no link between the parents' view on which toys were more appropriate for boys or girls, and the children's choice.

    Dr Brenda Todd said: “Children of this age are already exposed to much socialization. Boys may be given ‘toys that go' while girls get toys they can care for, which may help shape their preference. But these findings agree with the former idea that children show natural interests in particular kinds of toys. There could be a biological basis for their choices. Males through evolution have been adapted to prefer moving objects, probably through hunting instincts（本能）, while girls prefer warmer colors such as pink, the color of a newborn baby.”

    Most of the people who appear most often and most gloriously in the history books are great conquerors and generals and soldiers, whereas the people who really helped civilization forward are often never mentioned at all. We do not know who first set a broken leg, or launched a seaworthy boat, or calculated the length of the year, or manured(施肥)a field; but we know all about the killers and destroyers. People think a great deal of them, so much so that on all the highest pillars (纪念柱) in the great cities of the world you will find the figure of a conqueror or a general or a soldier. And I think most people believe that the greatest countries are those that have beaten in battle the greatest number of other countries and ruled over them as conquerors. It is just possible they are, but they are not the most civilized.

    Animals fight; so do savages (野蛮人); hence to be good at fighting is to be good in the way in which an animal or a savage is good, but it is not to be civilized. Even being good at getting other people to fight for you and telling them how to do it most efficiently －this, after all, is what conquerors and generals have done －is not being civilized. People fight to settle quarrels. Fighting means killing, and civilized peoples ought to be able to find some way of settling their disputes other than by seeing which side can kill off the greater number of the other side, and then saying that that side which has killed most has won. And it not only has won, but, because it has won, has been in the right. For that is what going to war means; it means saying that might is right.

    That is what the story of mankind has on the whole been like. Even our own age has fought the two greatest wars in history, in which millions of people were killed or disabled. And while today it is true that people do not fight and kill each other in the streets －while, that is to say, we have got to the stage of keeping the rules and behaving properly to each other in daily life － nations and countries have not learnt to do this yet, and still behave like savages.

    St Moritz, the showiest of Switzerland's Alpine resorts (旅游胜地), is no ordinary ski town. It's responsible for winter tourism as we know it today. It was a small band of English holidaymakers that changed Switzerland forever. In 1864 a bet took place between hotelier Johannes Badrutt and the vacationers on a damp September evening in St Moritz. As they sat around the fire at the Engadiner Kulm Hotel, concerned about returning to the foggy London winter, the Swiss manager saw a golden opportunity.

    “You holiday here in summer,” he challenged them over a bottle of red wine. “Why not enjoy the mountains year-round? Winter is so pleasant that on fine days you can even walk without a jacket.” Attracted by the promise of clean skies against a backdrop of towering peaks, the Englishmen were pleased to accept it; up until then, St Moritz had been a modest hiking destination in July and August. But if Badrutt's promise proved false, the hotelier would pay for their journey and winter-long stay. How could they lose?

    Come mid-December, the group of men returned to Switzerland. Towards the end of their week-long journey, sitting on a horse-pulled sledge and wrapped head-to-toe in furs, they went through the 2,284m Julier Pass in southeastern Switzerland. But by the time of their arrival in St Moritz, the skies had cleared, they were sweating abundantly, and Badrutt, jacketless and with his shirt sleeves rolled up, was there to greet them.

    Of course, Badrutt won the bet. Word quickly spread throughout Britain about St Moritz's distinctive climate—dry and sunny with a high degree of snow certainty. Year-round tourism landed the Alpine town of St Moritz.

    That Badrutt almost single-handedly marketed this undeveloped winter wonderland is a little unbelievable. The first tourist office in Switzerland had been established in the same year as the bet. Other resorts like the ones in Davos and Grindelwald were also popping up then. The story of St Moritz is, in some ways, also a tale of social transformation. But what Badrutt did made the Swiss mountains accessible in a way that no one else had done before, so his role as pioneer cannot be downplayed.

    Parents often believe that they have a good relationship with their teenagers. But last summer, Joanna and Henry noticed a change in their older son. Suddenly he seemed to be talking far more to his friends than to his parents. "The door to his room is always shut." Joanna noted.

    Tina and Mark noticed similar changes in their 14-year-old daughter. "She used to sit in my arms on the sofa and talk with me," said Mark. "Now we joke that she does this only when she wants something. Sometimes she wants to be treated like a little girl and sometimes like a young lady. The problem is figuring out which time is which."

    Before age 11, children like to tell their parents what's on their minds. "In fact, parents are first on the list." said Michael Riera, author of Uncommon Sense for Parents with Teenagers. "This completely changes during the teen years." Riera explained. "They talk to their friends first, then maybe their teachers, and their parents last."

    Parents who know what's going on in their teenagers' lives are in the best position to help them. To break down the wall of silence, parents should create chances to understand what their children want to say, and try to find ways to talk and write to them. And they must give their children a mental (思想的) break, for children also need freedom, though young. Another thing parents should remember is that to be a friend, not a manager, with their children is a better way to know them.

    At a comedy night at Johns Hopkins Univerity in Maryland, members of the school's comedy(喜剧) club bring lots of laughter to their classmates with funny speeches and humorous body movements. These college student comedian's humour entertains busy, young people and eases their stress.

    Yet the club member Arella Shua says comedy is serious work. Every comedy starts as an individual project-- each member writes their own material. Then they try it out in weekly club meetings where all club members read the material, going joke by joke and seeing what works and what doesnt. Nothing unsatisfactory will be compromised(妥协). In this way comes a satisfying comedy.

    Ariella joined the club last year. Now she does not go anywhere without bringing something on which she can take notes. "Whenever I just have a thought in my head or when I see something or overhear someone saying something in the library, I just put it down, "Arielae explained. "when I'm trying to write my own set, I go through that……to see if there is anything in there that I can use."

    Club president Nicholas Scandura finds writng one of the many skills he has developed since joining the club."Writing jokes takes a lot of critical thinking." he said. The club gives its members a sense of community. When they meet, they share funny experiences. tell jokes and laugh.

    Harry Kuperstein discovered the club was a natural fit. Noticing the funny qualities of different situations improved his way of looking at the world. Becoming an active member also helped him work on the future skills he'll need as a medical doctor. "Having jokes ready to go might help smooth these interactions and make you a better public speaker, " he said.
