People are living longer than ever, but for some reason, women are living longer than men. A baby boy born in the United States in 2003 can expect to live to be about 73; a baby girl, about 79. This is indeed a wide gap, and no one really knows why it exists. The greater longevity (长寿) of woman, however, has been known for centuries. It was, for example, described in the seventeenth century. However, the difference was smaller then—the gap is growing.
A number of reasons have been proposed to account for the differences. The gap is greatest in industrialized societies, so it has been suggested that woman are less susceptible to work strains that may raise the risk of heart disease and alcoholism. Sociologists also tell us that woman are encouraged to be less adventurous than men (and this may be why they are more careful drivers, involved in fewer accidents).
Even smoking has been implicated in the age discrepancy. It was once suggested that working women are more likely to smoke and as more women entered the work force, the age gap would begin to close, because smoking is related to earlier deaths. Now, however, we see more women smoking and they still tend to live longer although their lung cancer rate is climbing sharply.
One puzzling aspect of the problem is that women do not appear to be as health as men. That is, they report far more illness. But when a man reports an illness, it is more likely to be serious.
Some researches have suggested that men may die earlier because their health is more strongly related to their emotions. For example, men tend to die sooner after losing a spouse than women do. Men even seem to be more weakened by loss of a job. (Both of these are linked with a marked decrease in the effectiveness of the immune system.) Among men, death follows retirement with an alarming promptness.
Perhaps we are searching for the answers too close to the surface of the problem. Perhaps the answers lie deeper in our biological heritage. After all, the phenomenon is not isolated to humans. Females have the edge among virtually all mammalian (哺乳动物的) species, in that they generally live longer. Furthermore, in many of these species the differences begin at the moment of conception; there are more male miscarriages (流产) . In humans, after birth, more baby boys than baby girls die.
The word "edge" in Paragraph 6 means "_____."
选项
A、margin
B、side
C、quality
D、advantage
答案
D
解析
margin利润,余裕:side方面:quality质量;advantage优势,利益。通篇都在谈论女性比男性在寿命方面更有优势,由此优势类推到几乎所有的哺乳动物中,雌性都活得更长些。故答案选D。
