  答案解析:

  1. 【答案】 A

  【解析】assume 意为“假定,设想”,多用于未证实的假定,根据题意,“早期的科学家,假定非人类动物的社会生活几乎完全是天生的,或是由遗传决定的”,所以A 项为正确答案。B 项adopt 意为“采用,接受” ; C 项believe 意为“相信” ; D 项surmise 意为“猜测,推测”,相当于“guess”。如:She surmised as such . (她如此猜测。)

  2. 【答案】C

  【解析】considerable 意为“相当大(或多)的,值得考虑的,相当可观的”,符合题意。A 项Considerate 意为“体谅的,为别人着想的”; B 项considered 意为“经过考虑的,被尊重的”; D 项considering 意为“就… … 而论”。显然A 、B 、D 三项意思不符。

  3 . 【答案】 D

  【解析】 A 项What ' s more 可表示递进;B 项Hence 意为“因此,所以”,表示因果关系。文中上一段提到“学习是动物的社会生活的一部分”,第二段接着讲“学习发生在动物小时候的印象中期”,两段间不存在递进或因果关系。But 在表转折时一般不与句子分开,所以D 项However 为正确答案。

  4. 【答案】 A

  【解析】A 项clarifies 意为“使清楚,阐明”,如:The government has time and again clarified its position on equal pay for women . (政府已经反复阐明政府对男女同工同酬的立场。)B 项。lassifies 意为“分类,使… … 成为机密”。C 项defines 意为“下定义,界定”。D 项outlines 意为“画轮廓,拟大纲”。根据原文的意思:“一个例证很好地阐明了‘印象’的本质”。所以A 项darifies 为最佳答案。

  5 . 【答案】 A

  【解析】fix on 为固定搭配,意为“选定,确定,决定”。如:We ' ve fixed on the 14th of April for the wedding . (我们决定4 月14 日结婚。)

  6.【答案】 B

  【 解析】 此处可翻译为:“如果在‘印象’发生时,用篮球或公文包代替母鸭,小鸭子也许会跟随它们。”B 项Substituted 意为“替代;调换(常与for 连用),”如:Substituted A fo : B ,意为“用A 代替B”。appropriated 是“拨作(款项等)供专用”,如:The 即vernment appropriated a large sum of money for building schools . (政府拨出一大笔钱修建学校。)assigned 意为“指派” ; distributed 意为“分发,分配”。只有B 选项符合题意,所以B 为正确答案。

  7 .【答案】 D

  【解析】D 项altered 意为“改变,更改”,相当于Change ,符合题意。A 项varied 意为“变化,使不同(强调范围变化)" , vary from … to … “从… … 到… … 不等;在… … 到… … 之间”,如:The temperature varies from time to time . (温度常常变化。)B 项deviated 意为“越出正轨,违反”。C 项differed 意为“使相异”。

  8. 【答案】 A

  【 解析】 fashioned 在这里作动词,意为“构成,做成… … 形状”。如:He fashioned the clay into a jar . (他用豁土做成一个罐子。)B 项modified 意为“更改,修改” ; C 项influenced 意为“影响,改变” ; D 项affected 意为“影响,使感动”。显然,B 、C 、D 选项不符合题意。

  9 . 【答案】 A

  【解析】 by instinct 为固定用法,意为“出于本能”。如:Birds learn to fly by instinct.(鸟儿学飞是出于本能。)

  10. 【答案】B

  【解析】这句话译为:“大猩猩通常会成为很好的母亲。”make 在这里意为“变为,证明为”,如:He will make her a good husband . (他将成为她的好丈夫。)
