It was enough to make anyone say Hullo! The incredible was visible to them all. The lamp hung upside down in the air, burning quietly with its flame pointing down.
Mr. Fotheringay stood with a forefinger stretched out and the troubled face of one expecting a terrible crash.
the troubled face of one expecting a terrible crash如何理解？of one =of a person字面意思是一个人的烦恼表情？of介词的意思是？关于吗？expecting a terrible crash修饰one。一个生活怕摔碎的烦恼表情？
the troubled face of one expecting a terrible crash.
the face of 后面的宾语应该是某人，而不是某件事。因此one expecting a terrible crash不是动名词复合结构，而是不定代词后接目前分词短语作定语。
