It is thought that crying is hardly an activity encouraged by society. Tear, 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 form 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.
Other researchers are investigating the usefulness of tears as a means of diagnosing human ills and monitoring drugs. At Tulane University’s Teat 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.

解析

试题分析：本文主要描述了流眼泪的好处和功能。新的研究表明情感眼泪可能起到减缓压力的作用，也可以诊断病情和指导用药。
小题1:细节理解题。从第一段第二句The shedder of tears (落泪者) is to apologize...及第三句The observer of tears is likely to do everything possible to put an end to the emotional tears. 的信息可得知答案为C。
小题2:排除法。从倒数第二段emotional tears may play a direct role in alleviating stress可排除B项，扩大了范围。 从第三段crying is a way to ask for assistance form others, the shedding of tears is hardly necessary to get help可排除C，根据crying has one or more functions that enhance (increase) survival排除D，表达错误，故选A。
小题3:综合全文，尤其是从文章倒数第二段中心句the new studies suggest that emotional tears may play a direct role in alleviating stress及最后一段中心句the usefulness of tears as a means of diagnosing human ills and monitoring drugs可得知文章主要讲述了流泪的好处和功能，故选择答案B。
