台湾籍旅美老师今天交给我们的句子是：
Victorians were not constantly miserable -- they just usually got serious when they thought a portrait was being taken. As cameras became more common and photography improved, aesthetics changed and smiles returned.
维多利亚时期的人们并非过得很凄惨，他们只是通常会在拍照时，板着一张脸。自从相机变得越来越普遍且摄影技术越来越进步后，审美观就改变了，相片中人们的笑容也回来了。
