问题 Passage 2
For centuries in Spain and Latin America, heading home for lunch and a snooze with the familywas some thing like a national right, but with global capitalism standardizing work hours, this idyllichabit is fast becoming an endangered pleasure. Ironically, all this is happening just as researchers arebeginning to note the health benefits of the afternoon nap.
According to a nationwide survey, less than 25 percent of Spaniards still enjoy siestas. And likeSpain, much of Latin America has adopted Americanized work schedules, too, with shortened lunchtimes and more rigid work hours. Last year the Mexican government passed a law limiting lunchbreaks to one hour and requiring its employees to work their eight-hour shift between 7 a.m. and 6 p.m.
Before the mandate, workers would break up the shift--going home midday for a long break withthe family and returning to work until about 9 or 10 p.m. The idea of siesta is changing in Greece,Italy and Portugal, too, as they rush to join their more "industrious" counterparts in the globalmarket.
Most Americans I know covet sleep, but the idea of taking a nap mid-afternoon equates withlaziness, un employment and general sneakiness. Yet according to a National Sleep Survey poll,65percent of adults do not get enough sleep. Numerous scientific studies document the benefits of naptaking, including one 1997 study on the deleterious effects of sleep deprivation in the journal Inter-nal Medicine. The researchers found that fatigue harms not only marital and social relations butworker productivity.
According to Mark Rosekind, a former NASA scientist and founder of Solutions in Cupertino,Calif., which educates businesses about the advantages of sanctioning naps, we′ re biologically pro-grammed to get sleepy between 3 and 5 p.m. and 3 and 5 a.m. Our internal timekeeper--called thecircadian clock--operates on a 24-hour rotation and every 12 hours there′s a dip. In accordancewith these natural sleep rhythms, Rosekind recommends that naps be either for 40 minutes or for twohours. Latin American countries, asserts Rosekind, have had it right all along. They′ ve been in syncwith their clocks; we haven′t.
Since most of the world is sleep-deprived, getting well under the recommended eight hours anight (adults get an average of 6.5 hours nightly), we usually operate on a kind of idle midday. Napsare even more useful now that most of us forfeit sleep because of insane work schedules, longercommute times and stress, In a study published last April, Brazilian medical researchers noted thatblood pressure and arterial blood pressure dropped during a siesta.
In the second sentence of Paragraph 1, "all this" refers to __________.

选项 A.the habit of napping

B.the standardizing of work hours

C.the decline of the siesta tradition

D.the growth of global capitalism

答案C

解析指代题。“all this”所在的上下文的大意是:几百年来,西班牙人和拉丁美洲人一直把回家吃午饭、午睡当成一种国民权利,但是随着资本主义全球化的进程使工作时间标准化.这种田园般的生活习惯正迅速演变成一种岌岌可危的享受。具有讽刺意味的是:所有这一切(all this)发生的同时,研究人员也开始注意到午睡对于身体健康的种种好处。由此可见all this指的是上文中的this idyllic habit is fast becoming anendangered pleasure,其中idyllic habit、endangered分别对应C项中的siesta tradition(午睡习惯)和decline(衰退)。因此.C项正确。
