v 完形填空原文
Trust is a tricky business. On the one hand,it’s a necessary condition for many worthwhile things: child care,friendships,etc. On the other hand,putting your faith in the wrong place often carries a high price.
Then,why do we trust at all? Well,because it feels good. When people place their trust in an individual or an institution,their brains release oxytocin,a hormone that produces pleasurable feelings and triggers the herding instinct that prompts humans to connect with one another. Scientists have found that exposure to this hormone puts us in a trusting mood. In a Swiss study,researchers sprayed oxytocin into a nose of half the subjects; those subjects were ready to lend significantly higher amounts of money to strangers than were their counterparts who inhaled something else.
Lucky for us,we also have a sixth sense for dishonesty that may protect us. A Canadian study found that children as young as 14 months can differentiate between a credible person and a dishonest one. Sixty toddlers were each introduced to an adult tester holding a plastic container. The tester would ask,‘what’s in here?’ before looking into the container,smiling,and exclaiming,‘Wow!’ Each subject was then invited to look inside. Half of them found a toy,the other half discovered the container was empty and realized the tester had fooled them.
Among the children who had not been tricked,the majoring were willing to cooperate with the tester in learning a new skill,demonstrating that they trusted his leadership. In contrast,only five of the 30 children paired with the unreliable tester participated in a follow-up activity.

v 全文参考翻译
信任是一件复杂的事情。一方面，它是许多有价值的事情的必要条件：儿童看护，友谊等等。另一方面，把你的信任放在错误的地方往往会付出高昂的代价。
那么，我们究竟为什么要信任呢?因为这样感觉很好。当人们信任一个人或一个机构时，他们的大脑会释放催产素，这是一种能产生愉悦感并触发群居本能的荷尔蒙，它促使人们相互联系。科学家们发现，暴露在这种荷尔蒙中会让我们产生信任的情绪。在瑞士的一项研究中，研究人员将催产素喷洒到一半受试者的鼻子里;这些人愿意借给陌生人的钱数比吸入其他东西的人要多得多。
幸运的是，我们对不诚实也有第六感，这可能会保护我们。加拿大的一项研究发现，14个月大的孩子就能区分一个可信的人和一个不诚实的人。60个蹒跚学步的孩子每人被引导给一个拿着塑料容器的成人测试员。测试员会问：这里面是什么?，然后朝容器里看了看，微笑着惊叫道：哇!然后，每个被试都被邀请去看里面。其中一半的人找到了一个玩具，另一半人发现盒子是空的，并意识到测试者愚弄了他们。
在没有被骗的孩子中，大部分孩子愿意与测试者合作学习一项新技能，这表明他们信任测试者的领导能力。相反的是，30个与不可靠的测试者配对的孩子中只有5个参加了后续活动。
v 文章结构分析
本文第一段引出主题：信任。并且提到了信任的好处和坏处。
第二段介绍信任的原因及背后的科学依据，并举出了瑞士的一项研究来佐证。
第三段介绍对不诚实的防御机制，详细介绍了加拿大的一项研究。并在第四段介绍了这项研究的实验结果。
本篇完型填空采取总分结构，脉络清晰，向我们介绍了关于信任的这个科学研究。考研英语中不乏心理学相关的话题，同学们感兴趣的话可以多了解一下相关话题。当然如果没有时间也不用担心，即使考察到的话题我们没有太多相关背景知识，但只要掌握了完型文章的特点和做题方法一样也可以自如应对。
