单选题 Milan has prohibited the consumption and sale of alcohol to young teenagers in an effort to curb binge-drinking(抑制狂欢饮酒).
Parents of children under the age of 16 caught drinking wine or spirits will be liable to heavy fine(罚款) of up to 500 Euros($700).
A third of 11-year-olds in the city have alcohol related problems.
In a country where for centuries wine has been part of local culture the prohibition has comes as a shock.
But the authorities are deeply concerned about the increase in consumption of alcohol by children as young as 11 in the country"s industrial and financial capital.
So as an experiment, supplying alcohol-either wine or spirits-to youths under the age of 16 in bars, restaurants and liquor stores will be prohibited.
Heavy fines will be imposed on the parents of offending children and on shopkeepers or bar owners who serve them.
A national law prohibiting the sale of alcohol to under-16s is only loosely enforced(执行)，as Italian families are used to sometimes giving young children a teaspoon of wine as a family party treat.
In the past centuries, Italian children would sometimes even be given wine to drink in preference to water which was often polluted.
There has been a storm of protest by bar owners who refuse to act as alcohol police for young people.
But more Italians have realized that their old easy-going attitudes towards consumption of alcohol will have to change.
