【解析】细节理解题。根据最后一段中的“However,.Elfenbein notes that positive affectivepresence isn't naturally good.Psychopaths(精神变态者)are infamously charming,and maywell use their positive affective presence for calculating ends.Neither is negative affectivepresence necessarily always a bad thing in a leader”以及上文可知，故答案选B.35.A【解析】主旨大意题。根据第一段中的“A small body of psychology research supports theidea that the way a person tends to make others feel is a consistent and measurable part of hispersonality.Researchers call it“affective presence.”可得出本文话题是affective presence。下文围绕这个概念，解释了概念发现的背景，分析对立的两种affective presence的影响和优缺点。第二节36-40 FDBGC【文章导读】本文介绍了历史上奴隶制度的开始与结束。36.F【解析】由上下文中的三个动作seized;taken away from their homes和transported可知选项F中的shipped是最恰当的。37.D【解析】D选项中的aboard正好与下文介绍奴隶在船上的非人待遇相吻合。38.B【解析】B选项中的by crew表明是与海运有关系，另外to starve themselves也可以与上文的恐惧相对应。39.G【解析】G选项中的“the government allowed this unjust treatment of innocent people”与上文中的提到的“the people they could make use of for economic gain”以及下文中提到的“Because the slave trade was legal”皆相符。40.C【解析】此空需与前后句信息一致，故而只有C项符合。第三部分语言运用第一节【篇章导读】本文是一篇夹叙夹议的文章，主要讲述了作者在10岁的时候决定成为一名教师。通过观察自己的任课教师和自己成人后的从教经历，作者对教师这一职业有了更深的感悟。41-45 BDADB46-50 CCBDA51-55 ABDAC41.B英语参考答案第3页（共11页）
