这类现象英文短语可以用 "placebo effect" 来表示。
Placebo effect 来源于拉丁语，意思是 "I shall please"。在医学领域，它指的是某种没有明显生理作用的治疗方法或药物对患者症状的疗效。这种疗效并不是由药物本身所致，而是患者对药物的期望作用所引起的。
下面是一些英文例句及其中文翻译：
The patient's symptoms improved after taking the placebo, suggesting that the placebo effect was at work. (患者服用安慰剂后症状有所改善，这表明安慰剂效应在起作用。)
Some studies have shown that the placebo effect can be just as powerful as traditional treatments for certain conditions. (一些研究表明，对于某些病症，安慰剂效应可能和传统治疗方法一样有效。)
The placebo effect can be influenced by various factors, such as the patient's expectations and the doctor's demeanor. (安慰剂效应可能受到多种因素的影响，比如患者的期望和医生的态度。)
