全真模拟习题Unit 3-Passage3
In a world where sight and sound seem to reign supreme, all it takes is a cursory glance at the size of the perfume industry to realise that smell matters quite a lot, too. Odours are known to regulate moods, thoughts and even dating decisions, which is why any serious romantic will throw on the eau de toilette before going out for a night on the town. Yet in all these cases, those affected are aware of what they are smelling. Unlike the media of sight and sound, in which subliminal messages have been studied carefully, the potential power of subliminal smells has been neglected.
Wen Li and her colleagues at Northwestern University in Chicago are now changing that. In particular, they are investigating smells so faint that people say they cannot detect them. The idea is to see whether such smells can nevertheless change the way that people behave towards others.
Dr Li's experiment, the results of which have just been published in Psychological Science, employed 31 volunteers. These people were exposed to three different odours at low concentration. One was the fresh lemon scent of citral. The second was the neutral ethereal perfume of anisole. The third was the foul sweaty smell of valeric acid. And the concentrations really were low. In the case of valeric acid, for example, that concentration was seven parts per trillion—a level only just detectable by bloodhounds. As a control, Dr Li used a mineral oil that has no detectable smell at any concentration.
The participants were asked to sniff a jar containing either one of the three odours or the scentless oil, and then press a button to indicate whether they thought the jar smelled of anything. Immediately after that, a picture of a face would appear on a screen in front of them for just over a second. Each participant was asked to rate the face's “likeability”.
Dr Li found that the odours helped shape people's judgments about the faces when their responses indicated that they had not smelled anything. When someone had been exposed to valeric acid, for example, he tended to react negatively to a face. Exposure to citral, by contrast, made that face seem, on average, more friendly. (Obviously, the same face was not shown to any given participant more than once.) Even more intriguing, however, was that when participants did consciously perceive a smell, its effect on face-perception disappeared.
What is going on is unclear. If smells can carry useful information about personality (which is possible), then the effect would be expected to be the same whether or not the chemical in question is detected subliminally. If they do not carry such information, then it is hard to see what use the subliminal reaction is. Nevertheless, it is there.
The findings do, however, demonstrate what might be a powerful method of manipulation. Indeed, Dr Li considers the potential uses to be vast. Business meetings might be made more pleasant by releasing appropriate fragrances into the air in unsmellable amounts. Conversely, fights might be started by putting people in the presence of a faint foul odour. Advertising hoardings might benefit from a little olfactory tweaking and cinema audiences could be reduced to floods of tears at the appropriate moment. The sweet smell of success might, in other words, actually be undetectable.

题目分析：
1. Dr. Li is carrying out such an investigation in order to _____1. 李博士进行这项试验是为了_____
[A] find out how smells regulate moods in a subtle and nuanced way.[A] 探索气味是如何以一种细小微妙的方式调节人的情绪的。
[B] prove that smell plays an equally important role in daily life as that of sight and sound.[B]证明气味在人的生活中与人们的视觉、听觉一样起到了重要的作用。
[C] find out if people are sensitive to faint smells.[C] 探索人们是否对微弱的气味敏感。
[D] find out if faint smells could influence people’s judgement of others.[D]探索微弱的气味是否可以影响人们对他人的判断。
[答案]D
[难度系数] ☆☆☆
[分析] 推理题。文章介绍了李博士的实验，可以看出，该实验的对象是微弱的、人们靠嗅觉闻不到的气味。主要研究这种气味能否影响人们对于他人的行为，从试验详细描述来看，主要是人们对于他人的印象和判断。其中文章的第一段和第二段分别谈到“和视觉和声音媒介不同的是，它们其中微小的讯息已经被仔细研究过了，而细微的气味潜在的力量却被人们忽略了”、“特别的是，他们现在研究的气味非常微弱，人们都说他们感觉不到这些气味。他们想看看这些气味是不是也可以影响人们对他人的行为”等都说明了所有答案中D最为吻合文章的意思。
2.The mineral oil is used in Dr. Li’s experiment to _____2. 李博士的实验中矿物油是用来_____
[A] control the concentration of odours in a slightly detectable degree.[A] 在一个基本上很难察觉的程度上控制气味的浓度。
[B] act as a group of comparison with that of the other smells.[B] 作为和其他气味比较的一个对照组。
[C] regulate the participants’ moods by decreasing the smell’s concentration.[C] 通过降低气味的浓度来调节试验参与者的情绪。
[D] protect the participants from losing sense of smell.[D] 保证试验参与者不会丧失嗅觉。
[答案] B
[难度系数] ☆☆
[分析] 推理题。文章第三段指出，李博士在实验中用一种完全没有气味的矿物油作为control， 这里control的意思是在对照实验中被用作对照标准的一个或一组物体。不过这个意思比较生僻，考生可能不知道。那么可以根据实验中它的作用推断出来，它是绝对无味的，可以和其他的气味的实验结果对照。如果考生拥有足够的常识，也会知道在一般的科学实验中，为了保证试验结果的有效性，通常需要设置一个对照组。那么，选项B最为符合题意。
3. The word “likeability” (Line 4, Paragraph 4) most probably means_____3. “likeability” (第四段第四行)意思最可能指_____
[A] similarity.[A] 类似性。
[B] likeness.[B] 相似性。
[C] loveliness.[C] 可爱。
[D] likelihood.[D] 相似性，可能性。
[答案] C
[难度系数] ☆☆☆
[分析] 猜词题。根据上下文来判断该词的意思，试验要求参与者给看到的脸做一个判定，判定的内容可以根据实验结果看出来，是让参与者判断所看到的脸是否“可亲”，因此，可以断定这个词的意思是C。
4. When the participants conciously smelt the valeric acid, they tended to_____4.当参与者意识到自己闻到了颉草酸时，他们
趋向于____
[A] make negative judgement to a face.[A] 对看到的脸给以否定的判断。
[B] make positive judgement to a face.[B] 对看到的脸给以肯定的判断。
[C] make biased judgement to a face.[C] 对看到的脸给以偏颇的判断。
[D] make fair judgement to a face.[D] 对看到的脸给以公平的判断。
[答案]D
[难度系数] ☆☆☆
[分析]推理题。第五段提到很让人费解的是，当参与者意识到自己闻到了一种气味，那么对脸的判断的影响就消失了。实验中参与者在没有意识地闻到这种草酸味时，他会对脸有一种否定的判断，但是当他意识到自己闻到时，这种影响就没有了。那么可以推断，他对脸的判断就比较公允了，选项D最为符合。
5. From Dr. Li’s experiment, it can be infered that_____5. 由李博士的实验可以推断出_____
[A] one’s reaction to subliminal smells reflect useful information about his or her personality.[A]一个人对细微的气味的反应显示了有关于其个性的有用的信息。
[B] subliminal smells can influence people’s interaction with each other.[B] 细微的气味可以影响人们与他人的交往。
[C] subliminal smells have no effect on people’s conscious face-perception.[C] 细微的气味不能影响人们有意识地对脸的判断。
[D] subliminal smells turn out to be a means of powerful manipulation in terms of business success.[D] 细微的气味在商业成功的意义上来说是一种非常有利的控制手段。
[答案]B
[难度系数] ☆☆☆☆
[分析] 推理题。李博士的实验主要是为了看看细微的气味能否影响人们对他人的看法和印象,根据实验结果,参与者在闻了细微气味后会对看到的脸产生一定的反应,因此,可以得出结论,细微的气味能够影响对他人的行为。选项A，文章中提到有可能有这种可能，但是还没有证实。C不是该实验的一个主要结论，且该论点也没有得到证实。D选项的相关内容在文章的最后一段有所涉及，但是这只是对前景的推测，结论还没有得到证实。因此，答案应该选B选项。
参考译文：
在一个视觉和声音占绝对上风的世界里，我们只需随便看一下香水行业的规模就能明白气味也占有很重要的地位。大家知道，气味可以调节人的情绪、想法，甚至是约会决定，这也就是为什么人们晚上在城里赴约时总要喷上点香水。但是在所有的这些事例中，那些受影响的人都意识到自己闻到的是什么的。视觉和声音媒介中那些微小的讯息已经被仔细研究过了，而微弱气味潜在的力量却被人们忽略了。
李文和她在芝加哥西北大学的同事们现在就在改变这种状况。特别需要指出的是，他们现在研究的气味都极其微弱，以至于人们都说他们感觉不到这些气味。他们想看看这些气味是不是也可以影响人们对他人的行为。
李博士的实验结果刚刚发表在《心理科学》上，该实验有31名志愿者。这些志愿者身处三种低浓度的气味中，一种是新鲜柠檬的柠檬醛气味，第二种是茴香醚的中性轻香味，第三种是缬草酸的汗臭味。这三种气味的浓度都很低。比如，缬草酸的汗臭味浓度为万亿分之七，这种浓度只有警犬才能发觉。李博士在每种浓度中都用了一种矿物油作为对照，这种矿物油的气味是察觉不到的。
这些志愿者都被要求嗅装有某一种气味或无味的油罐子，然后再按下按钮表示自己是否闻到什么了。闻完后马上会在他们面前的屏幕上出现一张脸的图像，只显示一秒钟。然后每个人都会被要求断定这张脸的“可爱程度”。
李博士发现当人们认为自己没有闻到任何气味时，气味其实会影响人们对脸的评价。比如某人闻到缬草酸时，他对看到的脸就会有不好的反应。相反，闻到柠檬酸的味道一般会让脸看起来更友好些。(当然，每张脸只给同一个人看一次。)但是，更奇怪的是当参与者意识到自己闻到了某种味道时，上述影响就消失了。
这到底是怎么回事还不清楚。如果气味带有个性信息(这是有可能的)，那么不管这种化学是否可以被潜意识感觉到，其反应应当是一样的。如果不带有这种信息，就很难看出这种潜意识的反应有什么用了。但不管怎样，事实摆在我们面前。
但是这些发现展现出一些可能的强有力的控制方法。实际上，李博士认为这种潜力是巨大的。如果在喷洒些适当的人们闻不到的香味，商业会议会让人感觉更加舒适。相反，让人们在很微弱的臭味中，就可能发生争斗。广告牌可以受益于一点气味调节，而在适当时候为电影观众加些气味可能会使他们泪如泉涌。换句话说，胜利的甜蜜气味是无法觉察的。
文章剖析：
这篇文章介绍了细微气味对人们的影响。文章第一段讲述虽然气味在人们生活中占有重要地位，但是细微气味的潜在力量却为人所忽视;第二段讲述李博士正在进行研究细微气味的试验;第三、四、五段讲述了李博士试验的具体情况;第六段讲述还有待研究的问题;第七段讲述这个发现的意义和作用。
