Sloth may be seen as a sin, but some of history's most accomplished men were fond of lounging around. Leonardo da Vinci enjoyed napping. So did Albert Einstein and Winston Churchill. Richard Buckminster Fuller advocated taking 30-minute naps every six hours. He is reported to have abandoned the practice only because “his schedule conflicted with that of his business associates, who insisted on sleeping like other men.”No one has yet proved a correlation between napping and artistic brilliance or professional success, but an intriguing study published this week in the Archives of Internal Medicine claims to find a link between daytime siestas and good health. A team of researchers led by Androniki Naska of the University of Athens Medical School and Dimitrios Trichopoulos of Harvard's School of Public Health followed over 23,000 Greek patients with no history of coronary disease, cancer or stroke , for an average of six years. Their conclusion: napping just might save your life.
The study found that the group of adults who took siestas(defined as 30-minute naps)at least three times a week had a third fewer deaths from heart disease than anequivalent group who did not sleep at all during the day.
The benefit was greater for men than for women. (Whether women benefited at all was hard to estimate as there were too few deaths among them during the course of the study.) It was also greater for working men than for those who had retired. However, a number of previous studies done in the Mediterranean and in parts of Central America(where siestas remain common)have come up with conflicting results, but Dr Naska and Dr Trichopoulos argue that those studies have often been flawed. The subjects in some, for example, had survived heart attacks and may therefore have benefited more from napping than healthy individuals do.
Given that all of the subjects of this new study were Greek, could the much-celebrated Mediterranean diet deserve credit, rather than the siestas? The firm answer from Dr Trichopoulos is “No”. And he is in a good position to say so, for it was he who did the pioneering research that put olive oil and a plant-based diet on the scientific map in the first place. Unlike some other siesta studies, his was controlled for diet, smoking, exercise and other relevant variables. The earlier findings about the benefits of the Mediterranean diet are confirmed, he says, and napping seems to help on top of that.
Before buying a sofa for the office, however, it might be wise to consider the possibility of selection bias. Dr Trichopoulos concedes that “Type A” personalities, whose hard-working lives may make them prone to heart attacks, are also much less likely to take naps during the day. That bias might be skewing the study's results. Even so, he advises, “Take a nap if you can.”

2. Which of the following is TRUE about taking nap regularly?
A) One's possibility of dying from heart diseases is smaller.
B) One is surely to enjoy a long life with the habit of taking siestas.
C) Whether siestas benefit women is still unknown due to the limited member of women participating the test.
D) A working man usually outlives a working woman of similar age if he has the habit of siestas.

A) sleeping a lot
B) taking a nap every few hours
C) relaxing oneself
D) being lazy
4. Why is Dr Trichopoulos in a good position to deny the benefit from Mediterranean diet in this case?

C) Because Dr Trichopoulos knows nothing about the nutritious value of Mediterranean diet.
D) Because Mediterranean diet is notorious for its unhealthiness
5. Which of the following is TRUE according to the text?
A) The research fails to apply universally because it only studies a limited scope of sample that is short of representativeness
B) Most of those who have great achievements usually have the habit of taking siestas regularly.

主体句式：The study found that…
结构分析：这个句子的主要内容集中于that后面的宾语从句，其中该从句的主体结构为the group of adults had a third fewer deaths than an equivalent group。从句中的第一个who引导的定语从句用来修饰第一组成人的情况，其中注意到括号中的内容是对siestas的概念定义；从句中的第二个who引导的定语从句用来修饰第二组成人的情况。
句子译文：研究表明，那些每周至少午休3次，且每次至少睡30分钟的成人组与日间从不午休的成人组相比，由心脏病致死的几率低了1/3。
