单选题When it comes to the slowing economy, Ellen Spero isn't biting her nails just yet. But the 47-year-old manicurist isn't cutting, filling or polishing as nails as she'd like to, either. Most of her clients spend $12 to $50 weekly, but last month two longtime customers suddenly stopped showing up. Spero blames the softening economy. "I'm a good economic indicator," she says, "I provide a service that people can do without when they're concerned about saving some dollars." So Spero is downscaling, shopping at middle-brow Dillard's department store near her suburban Cleveland home, instead of Neiman Marcus, "I don't know it other clients are going to abandon me, too." She says. Even before Alan Greenspan's admission that America's red-hot economy is cooling, lots of working folks had already seen signs of the slowdown themselves. From car dealer-ships to Gap outlets, sales have been lagging for months as shoppers temper their spending. For retailers, who last year took in 24 percent of their revenue between Thanksgiving and Christmas, the cautious approach is coming at a crucial time. Already, experts say, holiday sales are off 7 percent from last year's pace. But don't sound any alarms just yet. Consumers seem only mildly concerned, not panicked, and many say they remain optimistic about the economy's long-term prospects, even as they do some modest belt-tightening. Consumers say they're not in despair because, despite the dreadful headlines, their own fortunes still feel pretty good. Home prices are holding steady in most regions. In Manhattan, "there's a new gold rush happening in the $4 million to $10 million range, predominantly fed by Wall Street bonuses." Says broker Barbara Corcoran. In San Francisco, prices are still rising even as frenzied overbidding quiets. "Instead of 20 to 30 offers, now maybe you only get two or three," says John Tealdi, a Bay Area real-estate broker. And most folks still feel pretty comfortable about their ability to find and keep a job. Many folks see silver linings to this slow-down. Potential home buyers would cheer for lower interest rates. Employers wouldn't mind a little fewer buddles in the job market. Many consumers seem to have been influenced by stock-market swings, which investors now view as a necessary ingredient to a sustained boom. Diners might see an upside, too. Getting a table at Manhattan's hot new Alain Ducasse restaurant used to be impossible. Not anymore. For that, Greenspan & Co. may still be worth toasting.

单选题{{B}}Text 4{{/B}} The Pakistani president, Gen. Pervez Musharraf, announced here today that a delegation of Pakistani officials would fly to the Taliban~ s headquarters in the southern Afghan city of Kandahar Monday to renew demands that the militia surrender Saudi fugitive Osama Bin Laden. U.S. officials have named Bin Laden, who has been given shelter by the Taliban rulers in Afghanistan, as the prime suspect in Tuesday's terrorist attacks in Washington and New York. "We are aware of the gravity of the situation and know that in the lives of nations, such situations do arise that require making important decisions," Musharraf said at a meeting with Pakistani newspaper editors. The Taliban's leader, Mohammad Omar, has refused to give up Bin Laden, claiming he is not responsible for the U.S. attacks. "The Pakistan government is leaning on the Taliban government to hand over Osama to save this entire region from catastrophe," said Najam Sethi, editor of the weekly newspaper Friday Times, who participated in the meeting with Musharraf. "I am not sure whether there is much chance of that happening, but the pressure is on from the Pakistan government." Pakistan has been a key supporter of the Taliban, which controls more than 90 percent of Afghanistan and has enforced a strict interpretation of Islamic law in the country. Omar, the Taliban leader, today convened an emergency meeting of clerics(圣职人员) in the Afghan capital, Kabul. "As regards the possible attack by America on the sacred soil of Afghanistan, veteran honorable clerics should come to Kabul for a sharia decision," Omar said in a statement broadcast on the Taliban's Radio Shariat today. Sharia is Islamic law. Omar, who reportedly left Ms. Kandahar headquarters several days ago in anticipation of a U. S. attack, asked Afghans to pray and read the Koran to meet what he called a "test", according to the statement. He indicated he would not attend the meeting of clerics, though he reportedly met with a small group of senior clerics today. The Pakistan-based Afghan Islamic Press reported today it had received a statement from Bin Laden, dispatched by an aide from an undisclosed location in Afghanistan, in which he denied involvement in last week's attacks on the World Trade Center and the Pentagon. "I am residing in Afghanistan," the statement said, "I have taken an oath of allegiance to Omar which does not allow me to do such things from Afghanistan. We have been blamed in the past, but we were not involved."

单选题King Juan Carlos of Spain once insisted "kings don"t abdicate, they die in their sleep." But embarrassing scandals and the popularity of the republican left in the recent Euro-elections have forced him to eat his words and stand down. So, does the Spanish crisis suggest that monarchy is seeing its last days? Does that mean the writing is on the wall for all European royals, with their magnificent uniforms and majestic lifestyles? The Spanish case provides arguments both for and against monarchy. When public opinion is particularly polarised, as it was following the end of the Franco regime, monarchs can rise above "mere" politics and "embody" a spirit of national unity. It is this apparent transcendence of politics that explains monarchs, continuing popularity as heads of state. And so, the Middle East excepted, Europe is the most monarch-infested region in the world, with 10 kingdoms (not counting Vatican City and Andorra). But unlike their absolutist counterparts in the Gulf and Asia, most royal families have survived because they allow voters to avoid the difficult search for a non-controversial but respected public figure. Even so, kings and queens undoubtedly have a downside. Symbolic of national unity as they claim to be, their very history—and sometimes the way they behave today—embodies outdated and indefensible privileges and inequalities. At a time when Thomes Piketty and other economists are warning of rising inequality and the increasing power of inherited wealth, it is bizarre that wealthy aristocratic families should still be the symbolic heart of modern democratic states. The most successful monarchies strive to abandon or hide their old aristocratic ways. Prince and princesses have day-jobs and ride bicycles, not horses (or helicopters). Even so, these are wealthy families who party with the international 1%, and media intrusiveness makes it increasingly difficult to maintain the right image. While Europe"s monarchies will no doubt be smart enough to survive for some time to come, it is the British royals who have most to fear from the Spanish example. It is only the Queen who has preserved the monarchy"s reputation with her rather ordinary (if well-heeled) granny style. The danger will come with Charles, who has both an expensive taste of lifestyle and a pretty hierarchical view of the world. He has failed to understand that monarchies have largely survived because they provide a service—as non-controversial and non-political heads of state. Charles ought to know that as English history shows, it is kings, not republicans, who are the monarchy"s worst enemies.

单选题When you speak on the telephone, you cannot use your facial expression, eye contact and gestures to help communicate your message. Your voice must do the job. A good voice is pleasant to listen to because it communicates a positive message. Keep in mind the following qualities of a good voice: Speak in a voice neither too loud nor too soft. Speak louder when giving important information. Speak slowly enough so that the listener has a chance to understand your messages without your having to repeat it. Keep in mind that as you speak the other person may be taking notes. Pronunciation is the correct way to say a word. To avoid mispronouncing(读错音)words, you may wish to check the pronunciation of unfamiliar words in the dictionary before you use them. People with an accent unlike yours may not understand your pronunciation of some words. You also may not understand the pronunciation of some of their words. In these cases, careful pronunciation is very important for effective communication. You may need to repeat or spell words that are unusual or easy to be misunderstood.
