一个春节的凌晨5点左右,一位被汽车撞成重伤的少校军官被一位好心的老工人用三轮车送到某市医院急诊室。被请出来的值班医师一见到刚刚苏醒过来的少校问:"带钱了吗?"少校摇了摇头,又赶紧吃力地说:"我是现役军人,能报销……"话未说完又昏迷过去。医生给当地部队打电话,未能搞清伤者身份,于是又回原房间睡觉去了。到早晨交接班时,发现少校军官已死于候诊室外长椅上。事后,某报记者走访了当值医师,他很委屈地说:"我多倒霉呀!白受了个处分。半夜里,他既没钱又没同伴,我怎么能相信他的话呢?医院里病人住院一分钱不交就溜走的还少吗?你去试试,不先交钱就给你看病的医院有哪家?"

Having a husband means an extra seven hours of housework each week for women, according to a new study. For men, getting married saves an hour of housework a week. “It’s a well-known pattern,” said lead researcher Frank Stafford at University of Michigan’s Institute for Social Research. “Men usually work more outside the home, while women take on more of the housework.”

He points out that differences among households (家庭) exist. But in general, marriage means more housework for women and less for men. “And the situation gets worse for women when they have children.” Stafford said.

Overall, times are changing in the American home. In 1976, women busied themselves with 26 weekly hours of sweeping-and-dusting work, compared with 17 hours in 2005. Men are taking on more housework, more than doubling their housework hours from six in 1976 to 13 in 2005.

Single women in their 20s and 30s did the least housework, about 12 weekly hours, while married women in their 60s and 70s did the most – about 21 hours a week.

Men showed a somewhat different pattern, with older men picking up the broom more often than younger men. Single men worked the hardest around the house, more than that of all other age groups of married men.

Having children increases housework even further. With more than three, for example, wives took on more of the extra work, clocking about 28 hours a week compared with husbands’10 hours.
