We can make mistakes at any age. Some mistakes we make are about money. But most mistakes are about people. "Did Jerry really care when I broken up with Helen?" "When I got that great job did Jim really feel good about it, as a friend?" "Or did be envy my luck?" "And Paul-- why didn't I pick up that he was friendly just because I had a car?" When we look back, doubts like these can make us feel bad. But when we look back, it's too late.
Why do we go wrong about our friends or our enemies? Sometimes what people say hides their real meaning. And if we don't really listen, we miss the feeling behind the words. Suppose someone tells you, "You're a lucky dog." Is he really on your side? If he says, "You're a lucky guy" or "You're a lucky gal," that's being friendly. But "lucky dog" ? There's a bit of envy in those words. Maybe he doesn't see it himself. But bringing in the "dog" bit puts you down a little. What be may be saying is that be doesn't think you deserve your luck.
"Just think of all the things you have to be thankful for" is another noise that says one thing and means another. It could mean that the speaker is trying to get you to see your problem as part of you life as a whole. But is he? Wrapped up in this phrase is the thought that your problem isn't important. It's telling you to think of all the starving people in the world when you haven't got a date for Saturday night.
How can you tell the real meaning behind someone's words? One way is to take a good look at the person talking. Do his words fit the way he looks? Does what he says square with the tone of voice? His posture? The look in his eyes? Stop and think. The minute you spend thinking about the real meaning of what people say to you may save another mistake.
Note: guy = boy; gal = girl
In paragraph 1, when the writer recalls some things that happened between him and his friends, ______.
A.he feels happy, thinking of how nice his friends were to him.
B.he feels he may not have "read" his friends' true feelings correctly.
C.he thinks it was a mistake to have broken up with his girlfriend.
D.he is sorry that his friends let him down.

Only two countries in the advanced world provide no guarantee for paid leave from work to care for a newborn child. Last spring one of the two, Australia, gave up the dubious distinction by establishing paid family leave starting in 2011. I wasn't surprised when this didn't make the news here in the United States—we're now the only wealthy country without such a policy.
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.
