第2篇 Youth Emancipation in Spain


The Spanish Government is so worried about the number of young adults still living with their parents that it has decided to help them leave the nest.
Around 55 percent of people aged 18--34 in Spain still sleep in their parents’ homes, says the latest report from the country’s state-run Institute of Youth.
To coax (劝诱) young people from their homes, the institute started a "Youth Emancipation (解放)" programme this month. The programme offers guidance in finding rooms and jobs.
Economists blame young people’s family dependence on the precarious (不稳定的) labour market and increasing housing prices. Housing prices have risen 17 percent a year since 2000.
Cultural reasons also contribute to the problem, say sociologists. Family ties in south Europe -- Italy, Portugal and Greece -- are per than those in middle and north Europe, said Spanish sociologist Almudena Moreno Minguez in her report "The Late Emancipation of Spanish Youth: Keys for Understanding".
"In general, young people in Spain firmly believe in the family as the main body around which their private life is organized," said Minguez.
In Spain -- especially in the countryside, it is not uncommon to find entire groups of aunts, uncles, cousins, nieces and nephews (外甥/侄子) all living on the same street. They regularly get together for Sunday dinner.
Parents’ tolerance (宽容) is another factor. Spanish parents accept late-night partying and are wary of setting bedtime rules.
"A child can arrive home at whatever time he wants. If parents complain he’ll put up a big fight and call the father a Fascist," said Jose Antonio Gomez Yanez, a sociologist at Carlos Ⅲ University in Madrid.
Mothers’ willingness to do children’s household chores worsens the problem. Dioni-sio Masso, a 60-year-old in Madrid, has three children in their 20s. The eldest, 28, has a girlfriend and a job. But life with mum is good.
"His mum does the wash and cooks for him; in the end, he lives well," Masso said.

The "Youth Emancipation" programme aims at helping young people ______.

A.fight for freedom

B.live in an independent way

C.fight against social injustice

D.get rid of family responsibilities
