According to a study by researchers at the University of Wisconsin Madison, feeling anxious can make typically neutral smells seem repugnant.
根据威斯康星麦迪逊大学研究人员的一份报告显示，焦虑的心情能够让典型的中性气味变得刺鼻。
The study involved a dozen volunteers who rated a panel of neutral smells.
该项研究邀请了12名志愿者并让他们辨别一组中性气味。
Then, while inside an MRI machine, subjects were made to feel anxious with disturbing images of car crashes and grisly war scenes.
然后通过向他们播放撞车和可怕的战争场景图像来使他们产生焦虑的情绪，并用核磁共振仪进行观察。
They were then once again asked to rank the panels of neutral smells.
接着，志愿者们被要求再次对这组中性气味进行辨别。
But now, after having been made anxious by the images, they described some of the smells as negative. So, what's going on?
但是由于之前看到的影片产生了焦虑感，他们这次则表示闻到的气体是刺鼻的。那会发生什么呢？
