25、ne the 56 of attraction, researchers paired 164 college classmates and had them talk for 3, 6 or 10 minutes so they could get a sense of each others individuality. Then students were asked to 57 what kind of relationship they were likely to build with their partners. After nine weeks, they reported
26、what happened.As it turned out, their 58 judgments often held true. Students seemed to 59 at an early stage who would best fit into their lives.The 60 KnowsScientists have also turned to nonhumans to increase understanding of attraction. Many animals give off pheromones natural chemicals that can be
27、 detected by, and then can produce a response in, other animals of the same species. Pheromones can signal that an animal is either ready to fight or is feeling 61 to partnerships. In contrast, humans do not seem to be as 62 as other animals at detecting such chemicals. Smell, however, does seem to

33、iar B. plain C. positiveD. irritating【解析】试题分析：古代和现代的人追求不同，现代人追求的是爱，但是科学家依然对爱还不是很清楚。51.A 考查副词以及对语境的理解 Instead 意为相反，Therefore意为因此， Moreover意为此外， Otherwise 意为否则。观察空格前后的句式结构，可以前面用的是you would not detect ,后面用的是you would see ，使用的动词不同，结构相同。由于前面有not，后面没有，所以可知此处表达为意思相反，所以答案为A。52.C 考查形容词以及对语境的理解 romantic意为浪漫的，
34、stressful意为压力的，central意为中心的，artificial 意为人工的。根据上一句话“life for ancient people seemed to center on hunting”及本句的“In modern times, finding love is ”，分析语境，知道这两个句子是把古代和现代的情况进行对比。前一句用了center ,后一句用central, 两者的关系是同根重现。53.B 考查名词以及对语境的理解 priority意为优先权，proof意为证明，possibility意为可能性，principle 意为原则。后两句的意思是：很容易准备一系列的有
35、关爱的现代故事。在当前的流行文化中，无数的故事和电影归类为爱情故事。根据这两句，的意思，结合上下文语境可知道本句的意思就是有很多证明的例子，所以答案为proof. 54.D 考查动词以及对语境的理解 tested 意为测试，imposed意为强加，changed意为改变，created 意为创造。根据本段的最后一句话“One thing is certain: The truth about love is not yet set in stone.确定了一件事情是：爱的真理还不确定”可以知道科学家研究的是爱是否能够创造，而不应该是测试，改变或者是强加。其中set in stone 就像中文里
36、说的“板上钉钉”，表示绝对不变。55.C 考查名词以及对语境的理解 appearances意为外表，virtues意为美德，similarities意为相似，passions 意为激情。根据划线部分前面的连词but 可以判断前后是转折的意思，而opposites意为相反的，所以答案为相似的。56.C 考查名词以及对语境的理解 illustrations意为说明，implications意为含义；暗示；牵连，卷入；可能的结果，影响，ingredients意为成分，intentions 意为意图，目的。根据小标题First Impression （第一印象）以及后面所描述的实验方法、内容和结果，可
37、以知道实验的目的是决定吸引力的成分。57.A 考查动词以及对语境的理解 predict 意为预测，investigate意为调查，diagnose意为诊断， recall 意为回忆。根据58题后面的judgment (判断)，可以知道此处的答案应该是和判断同义的词。又根据该句后面的句子“after nine weeks, they reported what happened.9周之后，报道发生了什么事情？”可以知道这一些是还没有发生的事情，也就是预测到的东西。58.B 考查形容词以及对语境的理解 critical意为批评的，initial意为原始的，random意为随意的，mature 意为
38、成熟的。根据第57题预测的东西，那么预测的东西相对而言就是原始的，最初的判断。59.B 考查动词以及对语境的理解 memorize 意为记忆，distinguish 意为区别，negotiate意为谈判， question意为疑问。根据前一句话的意思“结果证明他们最初的判断是正确的”，该句要表达的意思和前一句相同，也就是说“学生似乎能够在早期区别适合他们的生活人”。65.C 考查形容词以及对语境的理解 familiar意为熟悉，plain 意为普通的，positive意为积极的， irritating 意为无礼的。根据最后一句的表达“Seeing something attractive seems to cause happy thinking.看一些吸引力的事情似乎能够导致快乐的思考。”不能得出答案的表达应该是一种快乐思考，所以答案为positive积极的。【考点定位】 这是一篇说明文，阐述什么是爱？【名师点睛】这是一篇说明文，没有生词，主要是考查上下文理解和单词理解。需要正确理解4个单词的选项，尤其要注意一些一词多义的地方，如test, open, question。也要注意题目与题目直接的关系，如58题和59题；要关注小标题以及段落的开头和结尾。结合上下文，留意那些涉及到重现的题目。
