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 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 Deadly, 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 need to be impossible. Not anymore. For that, Greenspan & Co. may still be worth toasting. 第51题:By “Ellen Spero isn’t biting her nails just yet”(Line 1, Paragraph 1), the author means

[考点] 左心衰竭的早期症状与体征
[分析] 室性奔马律是舒张期的一种额外心音,它的产生机制一般认为是在心肌收缩力减退、心室壁顺应性减退情况下,在舒张早期心房血液快速注入左心室时引起已过度充盈的心室壁产生振动所致,从血流动力学角度看,它反映左室充盈压、左房压、肺毛细血管楔嵌压明显升高,是反映左室功能不全的一个体征。
左心衰竭最早出现的临床症状是劳力性呼吸困难,因进行体力活动时,回心血量增加,左心房压上升,肺淤血加重,所以出现呼吸困难。随着心功能不全的加重,患者可出现夜间阵发性呼吸困难、端坐呼吸以及心源性哮喘。
97.答案:E
[考点] 十二指肠溃疡手术适应证
[分析] 十二指肠溃疡手术适应证为:①严格内科治疗无效;②发生出血、梗阻、穿孑L等并发症者。为避免过度延长内科治疗时间而增加严重并发症的危险,现手术适应证放宽到:①溃疡病史长,发作频繁,症状严重;②纤维胃镜见溃疡深大,X线钡餐检查龛影较深;③既往有溃疡穿孔史,大出血或反复出血史,而溃疡仍呈活动性。十二指肠恶变率极低,因此,不应把预防十二指肠恶变作为手术指征。
