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 dealerships 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 slowdown. Potential home buyers would cheer for lower interest rates. Employers wouldn't mind a little fewer bubbles 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.
By "Ellen Spero isn't biting her nails just yet" (Line , Para. ), the author means ______ .
听力原文： Captain Joseph Mackey's airplane was flying over the ocean on its way to Great Britain when engine trouble started. He turned back and made a crash landing at night in the deep snow of Newfoundland. All the men in the plane were killed except Captain Mackey, who was badly hurt.
Captain Mackey waited .all the next morning for an airplane to come in search of him. In the afternoon he set out to find help. He went about a mile but found that he was too weak to go on through the snow. Half walking and half crawling, he made his way back to the plane.
The second day many planes passed above him, but none of the pilots saw him. The third day Captain Mackey heard a plane coming nearer and nearer, flying very slowly. It flew right over him and passed on. Then he gave up hope of being found. In a few minutes the plane returned, and the pi lot dipped one wing to get a clearer view.
The pilot came down closer for a better look, and then he saw Captain Mackey waving his arms. The pilot quickly climbed higher and sent a radio message. In a short time a plane came and dropped a sleeping bag, food, medicine, and tools for Captain Mackey.
