Barbie(芭比娃娃),believe it or not,is 50 this year and she's still as popular as ever.A doll is a doll,but Barbie illustrates how,over the last five decades,women have become a standard for judging what freedom really means. How women are treated in different countries tells you a lot about the politics and culture of where they live.

The doll that every little girl wants enables young children to test their possibilities in role playing,giving them a glimpse of what they might be when they grow up,whether to be frivolous or serious (or both).

But in many countries that's not an option. In Saudi Arabia,where woman can't drive or go out publicly unless covered,Barbie is banned. They think Barbie dolls are offensive to Islam(伊斯兰教) and a threat to morality.

In America,she represents the swiftly changing roles of women. Barbie is fun to tease but she's as American as miniskirts_and_pantsuits in her flexible identities and her “growth” from model to astronaut.

Barbie inspired a doll­revolution movement. When a Teen Talk Barbie was programmed electronically to say “Math class is tough”,she was criticized by a national women's group and was regarded as a bad stereotype. Some of her critics also say she's a bad influence because she's too thin and encourages anorexia,that she has run through too many stereotypes(固定模式),and that she lends too much significance to the fantasy stages of child's play.

In some Muslim countries, substitute Barbie dolls have been developed that promote traditional values,with their modest clothing and pro­family backgrounds. They are widely seen as an effort to resist the American dolls that have flooded the market.

Toy seller Masoumeh Rahimi welcomed the dolls,saying Barbie was “foreign to Muslim culture” because some of the dolls have little clothing. She said young girls who play with Barbie,could grow into women who reject Muslim values. “I think every Barbie doll is more harmful than an American missile,”Ms. Rahimi said.
