The smooth landing of shuttle(航天飞机)Discovery ended a flight that was successful in almost every respect but one: the dislodging of a big chunk of foam, like the one that doomed the Columbia. This flight was supposed to vault the shuttle fleet back into space after a prolonged grounding for repairs. But given the repeat of the very problem that two years of retooling was supposed to resolve ,the verdict is necessarily mixed. (1)Once again, the space agency has been forced to put off the flight until it can find a solution to the problem, and no one seems willing to guess how that may take.The Discovery astronauts performed superbly during their two-week mission, and the shuttle looked better than ever in some respects. (2)Space officials were justifiably happy that so much had gone well, despite daily worries over possible risks. the flight clearly achieved its prime objectives.The astronauts transferred tons of cargo to the international space station, which has been limping along overhead with a reduced crew and limited supplies carried up on smaller Russian spacecraft. (3)They replaced a broken device .repaired another and carted away a load of rubbish that had been left on the station,  showing the shuttle can bring full loads back down from space.This was the most scrutinized shuttle flight ever. with the vehicle undergoing close inspection while still in orbit. (4)New sensing and photographic equipment to look for potentially dangerous damage to the sensitive external skin proved valuable.  A new back flip maneuver allowed station astronauts to photograph the shuttle‘s underbelly, and an extra-long robotic arm enabled astronauts see parts of the shuttle that were previously out of sight.(5)The flood of images and the openness in discussing its uncertainties about potential hazards sometimes made it appear that the shuttle was about to fall apart,In the end the damage was clearly tolerable. A much-touted spacewalk to repair the shuttle's skin the first of its kind moved an astronaut close enough to pluck out some protruding material with his hand Preliminary evidence indicates that Discovery has far fewer nicks and gouges than shuttles on previous flights, perhaps showing that improvements to reduce the shedding of debris from the external fuel tank have had some success.

“The word ‘protection’ is no longer taboo (禁忌语)”. This short sentence, uttered by French President Nicolas Sarkozy last month, may have launched a new era in economic history. Why? For decades, Western leaders have believed that lowering trade barriers and tariffs was a natural good. Doing so, they reasoned, would lead to greater economic efficiency and productivity, which in turn would improve human welfare. Championing free trade thus became a moral, not just an economic, cause.These leaders, of course, weren’t acting out of unselfishness. They knew their economies were the most competitive, so they’d profit most from liberalization. And developing countries feared that their economies would be swamped by superior Western productivity. Today, however, the tables have turned—though few acknowledge it. The West continues to preach free trade, but practices it less and less. Asian, meanwhile, continues to plead for special protection but practices more and more free trade.That’s why Sarkozy’s words were so important: he finally injected some honesty into the trade debates. The truth is that large parts of the West are losing faith in tree trade, though few leaders admit it. Some economists are more honest. Paul Krugman is one of the few willing to acknowledge that protectionist arguments are returning. In the short run, there will be winners and losers under free trade. This, of course, is what capitalism is all about. But more and more of these losers will be in the West, Economists in the developed world used to love quoting Jonoph Schumpeter, who said that ‘creative destruction” was an essential part of capitalist growth. But they always assumed that destruction would happen over there. When Western workers began losing jobs, suddenly their leaders began to lose faith in their principles, Things have yet to reverse completely. But there’s clearly a negative trend in a Western theory and practice.A little hypocrisy (虚伪) is not in itself a serious problem. The real problem is that Western governments continue to insist that they retain control of the key global economic and financial institutions while drifting away from global liberalization. Lock at what’s happening at the IMF (International Monetary Fund). The Europeans have demanded that they keep the post of managing director. But all too often, Western officials put their own interests above everyone else’s when they dominate these global institutions.The time has therefore come for the Asians-who are clearly the new winners in today’s global economy-to provide more intellectual leadership in supporting free trade: Sadly, they have yet to do so. Unless Asians speak out, however, there’s a real danger that Adam Smith’s principles, which have brought so much good to the world, could gradually die. And that would leave all of us, worse off, in one way or another.1.It can be inferred that “protection” (Line 1, Para.1) means(  ).2.The Western leaders preach free trade because (  ).  3.By “the tables have turned” (Line 3-4, Para. 2) the author implies that (  ).  4.The Western economies used to like the idea of “creative destruction” because it (  ).  5.The author uses “IMF” was an example to illustrate the point that(  ).

For thousands of Canadians, bad service is neither make-believe nor amusing. It is an aggravating and worsening real-life phenomenon that encompasses behavior ranging from indifference and rudeness to naked hostility and even physical violence. Across the country, better business bureaus report a lengthening litany of complaints about contractors, car dealers, repair shops, moving companies, airlines and department stores. There is almost an adversarial feeling between businesses and consumers.Experts say there are several explanations for ill feeling in the marketplace. One is that customer service was an early and inevitable casualty when retailers responded to brutal competition by replacing employees with technology such as 1~800 numbers and voice mail. Another factor is that business generally has begun placing more emphasis on getting customers than on keeping them. Still another is that strident, frustrated and impatient shoppers vex shop owners and make them even less hospitable—especially at busier times of the year like Christmas. On both sides, simple courtesy has gone by the board. And for a multitude of consumers, service went with it.The Better Business Bureau at Vancouver gets 250 complaints a week, twice as many as five years ago. The bureau then had one complaints counsellor and now has four. People complain about being insulted, having their intelligence and integrity questioned, and being threatened. One will hear about people being hauled almost bodily out the door by somebody saying things like “I don’t have to serve you!” or “this is private property, get out and don’t come back!” What can customers do? If the bureau’s arbitration process fails to settle a dispute, a customer’s only recourse is to sue in small claims court. But because of the costs and time it takes, relatively few ever do.There is a lot of support for the notion that service has, in part, fallen victim to generational change. Many young people regard retailing “as just a dead-end job that you’re just going to do temporarily on your way to a real job”. Young clerks often lack both knowledge and civility. Employers are having to train young people in simple manners because that is not being done at home. Salespeople today, especially the younger ones, have grown up in a television-computer society where they’ve interacted largely with machines. One of the biggest complaints from businesses about graduates is the lack of interpersonal skills.What customers really want is access. They want to get through when they call, they don’t want busy signals, they don’t want interactive systems telling them to push one for this and two for that—they don’t want voice mail. And if customers do not get what they want, they defect. Some people go back to local small businesses: the Asian greengrocer, a Greek baker and a Greek fishmonger. They don’t wear name tags, but one gets to know them, all by name.46. At a business place of bad service, the worst one can get is ______.47. One of the reasons for such ill feeling in the marketplace is that ______.48. What has changed at Vancouver Beler Service Burcau in the past five years?49. Young clerks often lack interpersonal skills chiefly because they ______.50. The author’s attitude towards businesses and bad service is ______ them.
