The thought of holding a fixed grin as the camera performed its magical duties was too much to contemplate, and so a non-committal blank stare became the norm.
在相机施展魔法期间一直保持咧嘴笑的表情，这简直不堪设想，因此不置可否的茫然凝视就成了常态。
One explanation might be the loss of dignity displayed through a cheesy grin.
一种解释可能是，咧嘴假笑会显得有失尊严。
A toothy grin (especially when there were gaps or blackened teeth) lacked class: drunks, tramps, and music hall performers might gurn and grin with a smile as wide as Lewis Carroll’s gum-exposing Cheshire Cat, but it was not a becoming look for properly bred persons.
露齿的笑（尤其是牙齿有缝隙或发黑时）显得缺乏格调：醉汉、流浪汉和杂耍剧场的演员可能会做鬼脸、咧嘴大笑，笑容宽得像刘易斯·卡罗尔笔下露出牙龈的柴郡猫，但对于有良好教养的人来说，这可不是得体的样子。
