     It is thought that 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 (落泪者)

is likely to apologize, even when a great tragedy was the cause. The observer of tears is likely to do everything

possible to put an end to the emotional tears. But judging from recent studies of crying behavior, both those

responses to tears are often inappropriate and may even be counterproductive (适得其反).

     Humans are the only animals clearly known to shed emotional tears. Since evolution has given rise to few

purposeless physiological responses, it is logical to assume that crying has one or more functions that enhance

(increase) survival.

     Although some observers have suggested that crying is a way to ask for assistance from others (as a crying

baby might from its mother), the shedding of tears is hardly necessary to get help. Loud 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 reducing stress. University of

Minnesota researchers who are studying the chemical composition of tears have recently separated 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. 

     Other researchers are mvestigating the usefulness of tears as a means of making a careful examination of

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, to study the causes of "dry eye" syndrome (综合

症) and the effects of eye surgery, and perhaps even to measure exposure to environmental pollutants.
