5．Researchers in the psychology department at the University of California at Los Angeles （UCLA） have discovered a major difference in the way men and women respond to stress．This difference may explain why men are more likely to suffer from stress related disorders．
Until now，psychological research has maintained that both men and women have the same"fight or flight"reaction to stress．In other words，individuals either react with aggressive behavior，such as verbal or physical conflict （"fight"），or they react by withdrawing from the stressful situation （"flight"）．However，the UCLA research team found that men and women have quite different biological and behavioral responses to stress．While men often react to stress in the fight or flight response，women often have another kind of reaction which could be called"tend and befriend．"That is，they often react to stressful conditions by protecting and nurturing their young （"tend"），and by looking for social contact and support from others-especially other females （"befriend"）．
Scientists have long known that in the fight or flight reaction to stress，an important role is played by certain hormones（激素） released by the body．The UCLA research team suggests that the female tend or befriend response is also based on a hormone．This hormone，called oxytocin，has been studied in the context of childbirth，but now it is being studied for its role in the response of both men and women to stress．The principal investigator，Dr．Shelley E．Taylor，explained that"animals and people with high levels of oxytocin are calmer，more relaxed，more social，and less anxious．"While men also secrete（分泌） oxytocin，its effects are reduced by male hormones．
In terms of everyday behavior，the UCLA study found that women are far more likely than men to seek social contact when they are feeling stressed．They may phone relatives or friends，or ask directions if they are lost．
The study also showed how fathers and mothers responded differently when they came home to their family after a stressful day at work．The typical father wanted to be left alone to enjoy some peace and quiet．For a typical mother，coping with a bad day at work meant focusing her attention on her children and their needs．
The differences in responding to stress may explain the fact that women have lower frequency of stress related disorders such as high blood pressure or aggressive behavior．The tend and befriend regulatory（調(diào)節(jié)的） system may protect women against stress，and this may explain why women on average live longer than men．

分析 本文是一篇科技調(diào)查報(bào)告．本文主要介紹男女對(duì)壓力反應(yīng)的區(qū)別和原因以及如何克服壓力．
解答 32-35 CDCA
32．答案C．推理判斷題．根據(jù)第二段"men often react to stress in the fight-or-flight response"和"they react by withdrawing from the stressful situation （"flight"）"可判斷男人更可能從現(xiàn)實(shí)中逃脫出來．故選C．
33．答案D．推理判斷題．根據(jù)第三段 an important role is played by certain hormones（激素） released by the body和men also secrete（分泌）oxytocin，its effects are reduced by male hormones可判斷，激素扮演重要角色，但是男人也分泌oxytocin，但受男性荷爾蒙的影響，它的作用降低了．故選D．
34．答案C．主旨大意題．根據(jù)第一段的中心句：a major difference in the way men and women respond to stress．可知：本文由介紹男女對(duì)壓力反應(yīng)的區(qū)別和原因然后主要談男女如何克服壓力．
35．答案A．主旨大意題．本文是一篇科技調(diào)查報(bào)告．本文主要介紹男女對(duì)壓力反應(yīng)的區(qū)別和原因以及如何克服壓力．故選A．
