Question

12．People laugh and people cry．But it is thought that emotions such as anger，grief 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 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．Vo-cal （出聲的） cries would have been quite enough，more likely than tears to gain attention．So，it appears that there must be something special about tears themselves．
  Indeed，the new studies suggest that emotional tears may play a direct role in easing 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 looking into 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 r eport 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．
64．What does the phrase"both those responses"in Paragraph 1 refer to？D
A．Crying out of sorrow and shedding tears for happiness．
B．The embarrassment and unpleasant feelings of the observers．
C．Linking illness with crying and finding the chemical composition of tears．
D．The tear shedder's apology and the observer's effort to stop the crying．
65．It is known from the first paragraph thatA．
A．shedding tears gives unpleasant feelings to Americans
B．crying may often result in tragedy
C．crying usually wins sympathy from other people
D．one who sheds tears in public will be blamed
66．From the passage we can infer thatB．
A．it is unnatural for people to shed tears
B．we can reduce our stress by shedding tears
C．shedders of tears can't get help by crying loudly
D．unlike animals，humans can shed tears for survival．

Answer 1

分析 本文是一篇科教類閱讀，人開懷大笑，人們哭，但是人們認為的情緒，如憤怒、悲傷或喜悅，通常讓美國人感到不安和尷尬．本文以此展開，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．

解答 64．答案：D．細節(jié)理解題．根據(jù)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．可知，這些反應(yīng)指的是落淚者的道歉和觀察者的努力使其停止哭．故選D．
65．答案：A．細節(jié)理解題 根據(jù)第一段第二句But it is thought that emotions such as anger，or joy，typically make Americans feel uncomfortable and embarrassed．不管是出于悲傷，憤怒，快樂，眼淚通常讓美國人覺得尷尬不安．故選A．
66．答案：B．細節(jié)理解題 根據(jù)倒數(shù)第二段第一句emotional tears may play a direct role in alleviating stress．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 increase survival排除D．故選B．

點評 本文是一篇科教類閱讀，題目涉及多道細節(jié)理解題．做題時學(xué)生應(yīng)仔細閱讀原文，把握文章主要內(nèi)容，聯(lián)系文章上下文內(nèi)容并結(jié)合所給選項含義，從中選出正確答案，一定要做到有理有據(jù)，切忌胡亂猜測．
