试题解析

慢性阻塞性肺疾病

慢性阻塞性肺疾病是一种具有气流阻塞特征的慢性支气管炎和(或)肺气肿,可进一步发展为肺心病和呼吸衰竭的常见慢性疾病。与有害气体及有害颗粒的异常炎症反应有关,致残率和病死率很高,全球40岁以上发病率已高达9%~10%。慢性阻塞性肺疾病(chronic obstructive pulmonary disease,COPD)是一种常见的以持续气流受限为特征的可以预防和治疗的疾病,气流受限进行性发展,与气道和肺脏对有毒颗粒或气体的慢性炎性反应增强有关。

呼吸衰竭

呼吸衰竭是各种原因引起的肺通气和(或)换气功能严重障碍,以致不能进行有效的气体交换,导致缺氧伴(或不伴)二氧化碳潴留,从而引起一系列生理功能和代谢紊乱的临床综合征。在海平大气压下,于静息条件下呼吸室内空气,并排除心内解剖分流和原发于心排血量降低等情况后,动脉血氧分压(PaO2)低于8kPa(60mmHg),或伴有二氧化碳分压(PaCO2)高于6.65kPa(50mmHg),即为呼吸衰竭(简称呼衰)。

Questions 26 to 30 are based on the following passage. Exercise is one of the few factors with a positive role in long-term maintenance of body weight. Unfortunately, that message has not gotten through to the average American, who would rather try switching to “light” beer and low-calorie bread than increase physical exertion. The Centers for Disease Control, for example, found that fewer than one-fourth of overweight adults who were trying to shed pounds said they were combining exercise with their diet. In rejecting exercise, some people may be discouraged too much by caloric-expenditure charts: for example, one would have to briskly walk three miles just to work off the 275 calories in one delicious Danish pastry (小甜饼). Even exercise professionals concede half a point here. “Exercise by itself is a very tough way to lose weight,” says York Onnen, program director of the President’s Council on Physical Fitness and Sports. Still, exercise’s supporting role in weight reduction is vital. A study at the Boston University Medical Center of overweight police officers and other public employees confirmed that those who dieted without exercise regained almost all their old weight, while those who worked exercise into their daily routine maintained their new weight. If you have been sedentary (极少活动的) and decide to start walking one mile a day, the added exercise could burn an extra 100 calories daily. In a year’s time, assuming no increase in food intake, you could lose ten pounds. By increasing the distance of your walks gradually and making other dietary adjustments, you may lose even more weight. “Even exercise professionals concede half a point here” (Line 3, Para. 2) means “They ()”.
