Question

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 (落淚者) 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 (適得其反).
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（綜合癥）and the effects of eye surgery, and perhaps even to measure exposure to environmental pollutants.

Answer 1

小題1:C
小題2:A
小題3:B

試題分析：本文主要描述了流眼淚的好處和功能。新的研究表明情感眼淚可能起到減緩壓力的作用，也可以診斷病情和指導(dǎo)用藥。
小題1:細(xì)節(jié)理解題。從第一段第二句The shedder of tears (落淚者) 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. 的信息可得知答案為C。
小題2:排除法。從倒數(shù)第二段emotional tears may play a direct role in alleviating stress可排除B項(xiàng)，擴(kuò)大了范圍。 從第三段crying is a way to ask for assistance form others, the shedding of tears is hardly necessary to get help可排除C，根據(jù)crying has one or more functions that enhance (increase) survival排除D，表達(dá)錯(cuò)誤，故選A。
小題3:綜合全文，尤其是從文章倒數(shù)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可得知文章主要講述了流淚的好處和功能，故選擇答案B。
