U.S. airlines are seeing a major interruption because of hundreds of flights canceled due to the ash cloud from the Icelandic volcano, but European flight companies will face the biggest losses.
The airline business has been tough: The decline dramatically slowed traffic; February heavy snow forced U.S. airlines to cancel thousands of flights; and now the ashes from the volcano stopped all traffic in and out of northern Europe for days.
"For U.S. flight companies, it'll be a relatively short-term hit," said Michael Boyd, president of Boyd Group International, an aviation (航空学) consulting firm. "We think right now they're down about $80 million in terms of lost income, and they're down domestically about 80,000 passengers that would have been flying domestically but aren't because they can't get here."
Delta announced that volcano-related interruption grounded about 400 flights until Monday at a cost of $20 million in lost revenues. But compare that to the recent snowstorms, when the airline canceled 7,000 flights and lost $65 million in revenue.
The disruption has created uncertainty for customers, but analysts say U.S. airlines won't face as many costs as you might think. They are not flying in extra planes to handle the passengers in trouble because, airline analyst Robert Mann said, companies simply don't have them.
"Airlines run a very lean operation now," Mann said. "So, since there are no spare aircraft or crews, the airlines will attempt to maximize loads on every one of their aircraft that do fly. But it may take days, or in some cases a week or so, to get some of these customers to where they want to go."

Dear Economist,
My newly-wedded wife and I are deeply in love. There is, however, one issue that threatens the happiness of our marriage. I absolutely insist on shopping at Walmart. My wife, meanwhile, would rather avoid Walmart at all costs.
　　I have recently tried to convince her that not only does Walmart offer the lowest prices known to man, but that the chain is also a force for good―lower prices mean better standards of living for all consumers, increased global trade means a tighter-knit(紧密团结的) international community, and efficient operations translate into higher productivity growth for the economy. My wife complains about poor labour policies, the “fact” that Walmart squeezes suppliers, and that it puts local shops out of business.
　　Who is right? Will our marriage survive?
　　                                                                                                                                                  Brian Gee
Dear Brian,
I have to agree with you about Walmart. Jason Furman, then an economist at New York University, now an adviser to President Obama, famously argued in 2005 that Walmart was unwittingly (不知不觉地) a progressive success story. The chain’s prices don’t much affect me (I prefer Whole Foods) but Furman estimated that they benefited low-and-middle-income Americans to the sum of around $250 billion a year.
　　Walmart does not pay much, so it may depress wages. Then again, it may increase wages by offering jobs to the otherwise-unemployed. Either way, the benefits of low prices to Walmart shoppers far outweigh any seemingly reasonable costs to Walmart employees. And while it is true that Walmart employees tend to be poor, the same is true of Walmart shoppers.
　　Armed with this information you can face your wife with confidence. You are sure to win the conversation. The divorce is likely to be more argued.

II. 完形填空（共20小题，每小题1分，满分20分）
A while ago my family and I went sledding(滑雪橇) and as I watched my children climbing up the slope I started thinking.
Many people are convinced that most of today’s   26    problems are because of the “me” generation. Youngsters are just out for themselves and pay no   27   to others or their needs. Indeed, a common belief is that today’s youngsters won’t do anything   28  there is something in it for them.
Yet, while sledding, I saw a   29  side. I watched my two oldest children (then five and four) take my youngest(then two years old)by the hand to help her up the slippery slope  30   they went up. They would have been   31  without her, but not once did they try to sneak （溜掉）by her without helping. And when the sled  32  my two daughters was aimed toward the edge, it was my five year old son who ran to them to  33  them from falling and hurting themselves.
These children sometimes   34  among themselves and, on occasion, behave horribly. But I can  35  them shopping and know that they won’t ask for anything, I can talk to them about tsunami or hurricane victims and know that they will offer to  36  some of their own money to the cause, and I can ask them to play with those children  37  on the sideline(作为旁观者) and know that they will befriend（照顾）them.
Perhaps, therefore, the “me” generation is to blame  38   much of society’s problems—not the youngsters who want everything,   39  the adults who have taught themselves.
Most adults have been   41  at some time or another, sadly, many   42  that disappointment down to their children. Then the children learn to put themselves first!
Most young children want to help. We can  43  that feeling by teaching the lesson my children learned while sledding: Life is a slippery slope with  44  of bumps(撞伤) and bruises(擦伤), but we can all make it to the  45  if we remember to help those who need it.

三、阅读理解：
It is natural for young people to be critical of their parents at times and to blame them for most of the misunderstandings between them. They have always complained, more or less justly, that their parents are out of touch with modern ways; that they are possessive and dominant; that they do not trust their children to deal with crises; that they talk too much about certain problems and that they have no sense of humor, at least in parent-child relationships.
I think it is true that parents often underestimate their teenage children and also forget how they themselves felt when young.
Young people often irritate their parents with their choices in clothes and hairstyles, in entertainers and music. This is not their motive. They feel cut off from the adult world into which they have not yet been accepted. So they create a culture and society of their own. Then, if it turns out that their music or entertainers or vocabulary or clothes or hairstyles irritate their parents, this gives them additional enjoyment. They feel they are superior, at least in a small way, and that they are superior, at least in a small way, and that they are leaders in style and taste.
Sometimes you are resistant and proud because you do not want your parents to approve of what you do. If they did approve, it looks as if you are betraying your own age group. But in that case, you are assuming that you are the underdog: you can’t win but at least you can keep your honor. This is a passive way of looking at things. It is natural enough after long years of childhood, when you were completely under your parents’ control. But it ignores the fact that you are now beginning to be responsible for yourself.
If you plan to control your life, co-operation can be part of that plan. You can charm others, especially parents, into doing things the way you want. You can impress others with your sense of responsibility and initiative, so that they will give you the authority to do what you want to do.

How Much to Tip
You’re out to dinner. The food is delicious and the service is fine. You decide to leave a big fat tip. Why? The answer may not be as simple as you think.
Tipping, psychologists have found, is not just about service. Instead, studies have shown that tipping can be affected by psychological reactions to a series of different factors from the waiter’s choice of words, to how they carry themselves while taking orders, to the bill’s total. Even how much waiters remind customers of themselves can determine how much change they pocket by the end of the night.
“Studies before have shown that mimicry (模仿) brings into positive feelings for the mimicker,” wrote Rick van Baaren, a social psychology professor. “These studies show that people who are being mimicked become more generous toward the person who mimics them.”
So Rick van Baaren divided 59 waiters into two groups. He requested that half serve with a phrase such as, “Coming up!” Those in the other half were instructed to repeat the orders and preferences back to the customers. Rick van Baaren then compared their take-home. The results were clear — it pays to mimic your customer. The copycat(模仿者) waiters earned almost double the amount of tips to the other group.
Leonard Green and Joel Myerson, psychologists at Washington University in St. Louis, found the generosity of a tipper may be limited by his bill. After research on the 1,000 tips left for waiters, cabdrivers, hair stylists, they found tip percentages in these three areas dropped as customers’ bills went up. In fact, tip percentages appear to plateau (达到稳定水平) when bills topped $100 and a bill for $200 made the worker gain no bigger percentage tip than a bill for $100.
“That’s also a point of tipping,” Green says. “You have to give a little extra to the cab driver for being there to pick you up and something to the waiter for being there to serve you. If they weren’t there, you’d never get any service. So part of the idea of a tip is for just being there.”
【小题1】 Apart from service, how many other factors affecting the customers’ tipping are mentioned in the passage?
