今天的句子：
“There is no experimental evidence to support the idea that people get asthma or exacerbated asthma from exposure to fragrances,” says Wolkoff, who suspects psychology is at work instead.

参考译文：
Wolkoff说，“没有实验证据支持暴露于香气中会让人得哮喘或加重哮喘这一观点”，相反他怀疑起作用的是心理。芳香实验的一大问题在于，对于置身其中的人来说，盲法几乎是不可能的：实验对象知道他们正在闻一种气味，这会影响他们的反应。
