What’s the coolest kind of transportation(交通) for middle school students back from winter holidays？ A racing bike？ A car？ No, it’s a special kind of shoes called Heelys(暴走鞋). Heelys look just like common sports shoes, but they have a wheel(轮子) hidden(藏) in the heel(鞋跟). So instead of walking, kids can “fly” around in them. “Wearing Heelys is fun and cool!” said Wu Peng, a boy who wore them on his first day back at No. 6 Middle School in Beijing. Wu Peng said he loves the shoes so much that he wears them to go here and there. Sometimes he even follows his parents’ car to the supermarket in his Heelys! Other students also think they are very cool, but some aren’t so lucky with their Heelys. It’s said that some children fell down and got hurt while wearing these shoes. “Heelys wheels are in the heels of the shoes, so it’s easy to fall,” said Liu Rui, a doctor at the Hong Kong International Medical Clinic, Beijing.

The United States does have one explicit family policy, the Family and Medical Leave Act, passed in 1993. It entitles workers to as much as 12 weeks' unpaid leave for care of a newborn or dealing with a family medical problem. Despite the modesty of the benefit, the Chamber of Commerce and other business groups fought it bitterly, describing it as "government-run personnel management" and a "dangerous precedent". In fact, every step of the way, as (usually) Democratic leaders have tried to introduce work-family balance measures into the law, business groups have been strongly opposed. As Yale law professor Anne Alstott argues, justifying parental support depends on defining the family as a social good that, in some sense, society must pay for. In her book No Exit: What Parents Owe Their Children and What Society Owes Parents, she argues that parents are burdened in many ways in their lives: there is "no exit" when it comes to children. "Society expects—and needs—parents to provide their children with continuity of care, meaning the intensive, intimate care that human beings need to develop their intellectual, emotional and moral capabilities. And society expects—and needs—parents to persist in their roles for 18 years, or longer if needed." While most parents do this out of love, there are public penalties for not providing care. What parents do, in other words, is of deep concern to the state, for the obvious reason that caring for children is not only morally urgent but essential for the future of society. The state recognizes this in the large body of family laws that govern children' welfare, yet parents receive little help in meeting the life-changing obligations society imposes. To classify parenting as a personal choice for which there is no collective responsibility is not merely to ignore the social benefits of good parenting; really, it is to steal those benefits because they accrue (不断积累) to the whole of society as today's children become tomorrow's productive citizenry (公民). In fact, by some estimates, the value of parental investments in children, investments of time and money (including lost wages), is equal to 20-30% of gross domestic product. If these investments generate huge social benefits—as they clearly do—the benefits of providing more social support for the family should be that much clearer. 注意：此部分试题请在答题卡2上作答。 What do we learn about paid family leave from the first paragraph？ A．America is now the only developed country without the policy. B．It has now become a hot topic in the United States. C．It came as a surprise when Australia adopted the policy. D．Its meaning was clarified when it was established in Australia.
