11、r teenagers (青少年 ). 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 .” Joanns noted . Tina and Mark noticed similar changes in their 14-year-old daughter . “S

12、he used to cuddle up (蜷伏)with me on the sofa and talk ,” 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 t

13、o tell their parents whats 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 th

14、eir parents last .”Parents who know whats going on in their teenagers lives are in the best position to help them . To break down the wall of silence , parents should crate chances to understand what their children want to say , and try to find ways to talk and write to them . And they must give the

Scientists have studied consumer behavior recently and found that the look of the package has a great effect on the “quality” of the product and on how well it sells, because “Consumers generally cannot tell between a product a

21、nd its package. Many products are packages and many packages are products,” as Louis Cheskin, the first social scientist studying consumers feeling for packaging, noticed.Colors are one of the best tools in packaging.
