Of London's estimated (估计) 75,000 homeless people, a high percentage (百分率) are between the ages
of seventeen and twenty-five. Every year in Britain, over 5,000 young people leave home. Most of these
young people are over sixteen but some are even younger. Most of them are escaping (逃走、逃脱) from
an unhappy home life but a few of them just want the bright lights of a big city and a chance to earn (赚、挣)
some money. When their money runs out, some start begging or busking (街头卖艺) to earn money. They
start living on the streets and sleeping in doorways or in squats (蹲踞). Many of them return home after a
few months but the rest stay. Some say they prefer the freedom (自由) of the streets to life at home.
