Crying is hardly an activity encouraged by society. Tears, whether they are of sorrow, anger, or joy, typically make Americans feel uncomfortable and embarrassed. The shedder of tears is likely to apologize, even when a devastating tragedy was the provocation. The observer of tears is likely to do everything possible to put an end to the emotional outpouring. But judging from recent studies of crying behavior, links between illness and crying and the chemical composition of tears,
both those responses to tears
are often inappropriate and may even be
counterproductive
.
Humans are the only animals definitely known to shed emotiomal tears. Since evolution has given rise to few, if any, purposeless physiological responses, it is logical to assume that crying has one or more functions that enhance survival.
Although some observers have suggested that crying is a way to elicit assistance from others(as a crying baby might from its mother), the shedding of tears is hardly necessary to get help. Vocal cries would have been quite enough, more likely than tears to gain attention. So, it appears, there must be something special about tears themselves.
Indeed, the new studies suggest that emotional tears may play a direct role in alleviating stress. University of Minnesota researchers who are studying the chemical composition of tears have recently isolated two important chemicals from emotional tears. Both chemicals are found only in tears that are shed in response to emotion. Tears shed because of exposure to cut onion would contain no such substance.
Researchers at several other institutions are investigating the usefulness of tears as a means of diagnosing human ills and monitoring drugs.
At Tulane University’s Tear Analysis Laboratory Dr. Peter Kastl and his colleagues report that they can use tears to detect drug abuse and exposure to medication, to determine whether a contact lens fits properly of why it may be uncomfortable, to study the causes of "dry eye" syndrome and the effects of eye surgery, and perhaps even to measure exposure to environmental pollutants.
At Columbia University Dt. Liasy Faris and colleagues are studying tears for clues to the diagnosis of diseases away from the eyes. Tears can be obtained painlessly without invading the body and only tiny amounts are needed to perform highly refined analyses.
What does the author say about crying?
选项
A、It must have a role to play in man’ s survival.
B、It is a pointless physiological response to the environment.
C、It is meant to get attention and assistance.
D、It usually produces the desired effect.
答案
A
解析
细节题。按照出题顺序寻找至第二段,根据最后一句可知A项It must have a role to play in man’s survival(哭泣在人类生存中起一定作用)是对it is logical to assume that crying has one or more functions that enhance survival(认为哭泣有利于生存是符合逻辑的)的同义转述。
