Baby girls make their way directly for 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 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 infants aged nine months to 36 months. The babies were allowed to choose from seven toys. Some were stereotypically 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 significantly 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.”

Scott Langteau has this message for kids：spend less time playing video games.

It’s a message that many a mom and dad have tried to impress upon many a youngster (and some not?so?youngsters) who spend perhaps a bit too much time with game controllers in hand.

But the 40?year?old Langteau isn’t a parent.He’s a veteran (老手) of the video game industry—one who played producer on three “Medal of Honor” games and cofounded his own game development company.

Langteau has just published a children’s books called Sofa Boy，which tells the story of a kid who spends too much time sitting on the couch with controller clutched in hand and the rather terrible consequences that follow.

It’s a fairy tale plucked straight from Langteau’s own experiences as a lad with a fondness for video games and his own bouts with a bit of game addiction.But first，Langteau would like to make one thing clear，“I’m not saying that you shouldn’t play video games.I think video games are great.I think they do great things for kids.”Instead，Langteau says his book is all about a little something called moderation (克制)．

“It’s about being well rounded，” he says.“Just like with anything else，we all need to make sure that there’s a variety in what we do.”

Video gamers can be rather bad?tempered when it comes to accepting criticism about their favorite entertainment.And understandably so.After all，most people who go around talking about the dangers of playing video games tend to be outsiders—people who don’t play video games and certainly don’t understand that they can be a valuable and healthy form of entertainment.

But Langteau and Sofa Boy seem to be in a? unique position to deliver a message of gaming moderation that the young game masses might actually listen to.After all，this is a man who understands what it means to be a kid with a passion for games.His early experience has taught him a lesson.

When I wake up on summer mornings, I know I am going to my favorite place to volunteer and make a difference in someone's life just by being with him or her -- a summer school for autistic (患孤独症的)children.

      By helping the kids read or do math, I am not only teaching important skills but also helping them feel like any other kid. There are many wrong ideas about autism. The kids I work with can think and feel. They need help only in certain areas. 

      Of course, each kid is special. For example, some kids like to draw, and others like to sing.

      At the school, the kids learn through about 20 activities. These activities can help them learn skills they will need later in life.

      The very first day I volunteered, a boy came up to me, put his hand on my shoulder, and said “Hello”. From then on, I knew I could make a difference.

      Another boy loved to have me read books that can help him learn to read. Sometimes he could be encouraged to read a few words or sentences. Finally, one day during reading practice, he read nearly 220 words himself!

      Summer school is also a time for fun, Last summer, bagpipe(风箱)players came to perform. Most of us had our hands over our ears because they were so loud. When they asked for a volunteer from the audience, one girl raised her hand as high as she could, got up on stage, and even tried the bagpipes in front of everyone.

      Through these experiences, I realize that the challenges these kids face do not stop them from doing many amazing things. I'm teaching them, but they are teaching me more.
