同一时间，同一地点，前程百利小编又来了。今天为大家准备的是昂贵药物对人们心理作用的影响，一般人会认为越是昂贵的药物疗效就越好。下面托福听力小编给大家整理了一篇关于这方面的研究，快来围观积累托福听力背景材料吧！
We often equate quality with cost. Even when it comes to healthcare. The more pricey a drug, the better it must be.
我们总是将质量和成本等同起来。即使是医疗保健。药价越昂贵，疗效就越好。
And now a study finds that we even extend such financial assessment to placebos—people with Parkinson’s disease derived more benefits from a salt solution they were told was an expensive drug than from the same solution when it was described as being cheap medication.
最近一项研究表明，我们甚至扩大这种金融评估安慰剂—患有帕金森病的人，从盐溶液中的到了许多好处，他们被告知便宜的药物和昂贵的药物是同样的药效。
The placebo effect is well documented: people who think they’re receiving a real drug often improve, even when the treatment is just a sham. But why do placebos do anything, and why would one placebo have a greater effect than a different one?
安慰剂的效果非常可靠：即使非常不可靠，接受药物的人们感觉他们的到了改善。但是为什么安慰剂可以做一切事情，为什么安慰剂比另一个有更大的影响？
To examine whether the perceived cost could be a factor, researchers told 12 people with Parkinson’s that they would be receiving two formulations of a new medication. The patients believed that one version of the drug cost $100 a dose, while the other one cost 15 times as much.
为了检查成本是否会是一种因素，研究者告诉12个患有帕金森病的人，他们将会得到两个药物的新配方。病人相信这种药物会消费100美元一剂，而另一个会花费15美元。
The results? Participants who started with the supposedly high-priced drug showed 28 percent greater improvement in motor skills than those who got the cheaper placebo first.
结果呢？吃了所谓高价钱药的人感觉他们得到的比那些吃便宜药的人在动作机能方面多改善了28%。
The findings could point the way toward strategies that enhance the effectiveness of any drug regimen…by making us think that the treatment we’re getting is the best that money can buy.
这项发现在提高药效方面找出了新的方式。通过这种方式让他们认为这是通过金钱可以的到最好的治疗。
