"Yes…But what hot little hands you've got…That's because you're excited, Varya…What have you got for our supper to-night?" "Chicken and salad…It's a chicken just big enough for two…Then there is the salmon and sardines that were sent from town." The moon as though she had taken a pinch of snuff hid her face behind a cloud. Human happiness reminded her of her own loneliness, of her solitary couch beyond the hills and dales.

请问老师：

The moon as though she had taken a pinch of snuff hid her face behind a cloud.

1 这句话我的翻译直译：月亮把脸藏在云后，仿佛吸了一撮鼻烟。翻译对吗？还是有别的含义？

2 as though she had taken a pinch of snuff 是as though引导方式状语从句插入主谓之间吗，为什么会这样使用呢？
