单选题Like most people, I was brought up to look upon life as a process of getting. It was not until in my late thirties that I made this important discovery: giving-away makes life so much more exciting. One discovery I made about giving-away is that it is almost impossible to give away anything in this world without getting something back, though the return often comes in an unexpected form. One Sunday morning the local post office delivered an important special delivery letter to my home, though it was addressed to me at my office. I wrote the postmaster a note of appreciation. More than a year later I peeded a post-office box for a new business I was starting. I was told at the window that there were no boxes left, and that my name would have to go on a long waiting list. As I was about to leave, the postmaster appeared in the doorway. He had overheard our conversation. "Wasn't it you that wrote us that letter a year ago about delivering a special delivery to your home?" I said it was. "Well, you certainly are going to have a box in this post office if we have to make one for you. You don't know what a letter like that means to us. We usually get nothing but complaints. "

单选题1. As the U. S. economy tries to fight off a recession, has it found a way to avoid a knockout? So far, strength in many service industries is delivering a powerful counterpunch to hits from homebuilding, autos, and other goods-producing businesses. Despite the economy's tepid 0.6% growth rate last quarter, its service sector advanced a sturdy 3.5%. Consumer spending on goods plunged 2. 6% , but outlays for housing, medical care, and other services rose 3. 4%. Heading into the second quarter, while overall April payrolls shrunk by 20, 000 jobs, services added 90, 000. And in contrast to the weakness in manufacturing, the Institute for Supply Management says April service-sector activity continued to grow. 2. There's no denying the sector 's increasing impact on economic trends. Services make up almost 60% of gross domestic product, up from 55% a decade ago and 52% the decade before that. However, despite that growing influence, the more important engines of the business cycle have always been the goods-producing sector and construction, and they are taking an unusually heavy pounding. 3. This sharp divergence reflects the unique set of forces affecting the economy, especially consumers. The mix of tighter credit, the double hit to buying power from fewer jobs and higher prices for energy and food, and shrinking household wealth are killing demand for big-ticket consumer goods such as homes, cars, and other discretionary purchases. 4. Even as credit is drying up, jobs and incomes are shrinking. Since payrolls peaked in December, service employment through April is up 98, 000, but goods-producing jobs have plunged 358, 000. Overall, more people are having trouble finding full-time work. This year's rise in the number of people forced to work part-time is the fastest since the 2001 recession. Total hours worked began the second quarter well below their first-quarter level, and with hourly pay slowing, income growth, almost all of which has been eaten up by inflation over the past year, began the quarter on a weak note. 5. So far, despite consumers' weaker incomes, their savings rate remains close to the near-zero level of the past two years, implying they are spending about the same proportion of their earnings. That means factors other than income have not yet had a negative impact on spending, but that trend will be put to the test this quarter. 6. As household wealth, which had helped to make up for low savings, falls, along with credit availability and consumer confidence, consumers may soon be forced to save more of their incomes. There's a good chance the tax rebates will be either squirreled away or used to pay down credit cards. A shift to greater saving would tend to hit outlays for both goods and services. 7. On balance, recession forces appear to be getting stronger this quarter, not weaker. That will put even more pressure on the goods sector. And while the service sector's resilience may help to keep the recession mild, it won't necessarily be able to prevent one.

单选题A study released a little over a week ago, which found that eldest children end up, on average, with slightly higher IQ's than younger siblings, was a reminder that the fight for self- definition starts much earlier than freshman year. Families, whatever the relative intelligence of their members, often treat the firstborn as if he or she were the most academic, and the younger siblings fill in other niches: the wild one, the flirt. These imposed caricatures, in combination with the other labels that accumulate from the sandbox through adolescence, can seem over time like a miserable entourage of identities that can be silenced only with hours of therapy. But there's another way to see these alternate identities: as challenges that can sharpen psychological skills. In a country where reinvention is considered a birthright, many people seem to treat old identities the way Houdini treated padlocked boxes: something to wriggle free from, before being dragged down. And psychological research suggests that this ability can be a sign of mental resilience, of taking control of your own story rather than being trapped by it. The late-night bull sessions in college or at backyard barbecues are at some level like out-of-body experiences, allowing a re-coloring of past experience to connect with new acquaintances. A more obvious outlet to expand identity--and one that's available to those who have not or cannot escape the family and community where they're known and labeled-- is the Internet. Admittedly, a lot of the role-playing on the Internet can have a deviant quality. But researchers have found that many people who play life-simulation games, for example, set up the kind of families they would like to have had, even script alternate versions of their own role in the family or in a peer group. Decades ago the psychologist Erik Erickson conceived of middle age as a stage of life defined by a tension between stagnation and generativity-a healthy sense of guiding and nourishing the next generation, of helping the community. Ina series of studies, the Northwestern psychologist Dan P. McAdams has found that adults in their 40s and 50s whose lives show this generous quality - who often volunteer, who have a sense of accomplishment - tell very similar stories about how they came to be who they are. Whether they grew up in rural poverty or with views of Central Park, they told their life stories as series of redemptive lessons. When they failed a grade, they found a wonderful tutor, and later made the honor roll; when fired from a good job, they were forced to start their own business. This similarity in narrative constructions most likely reflects some agency, a willful reshaping and re-imagining of the past that informs the present. These are people who, whether pegged as nerds or rebels or plodders, have taken control of the stories that form their identities. In conversation, people are often willing to hand out thumbnail descriptions of themselves: "I'm kind of a hermit. " Or a talker, a practical joker, a striver, a snob, a morning person. But they are more likely to wince when someone else describes them so authoritatively. Maybe that's because they have come too far, shaken off enough old labels already. Like escape artists with a lifetime's experience slipping through chains, they don't want or need any additional work. Because while most people can leave their family niches, schoolyard nicknames and high school reputations behind, they don't ever entirely forget them.
