1.Halfway across the room, a small pistol in his hand, stood a man.
结构：全句只有1个谓语动词：stood.本句是完全倒装结构，按正常语序应该是：A small pistol in his hand, a man stood halfway across the room. 其中，a small pistol in his hand 是一个独立主格结构，修饰主语a man.
翻译：一名男子站在屋子中间，手里拿着一支枪。
2.They do not seem to like one another very much, neither are they too keen on conventional people.
结构：全句有2个谓语动词：do和are.本句的后半部分是一个主谓倒装的单句，按正常语序应该是：They are neither too keen on conventional people. 注意neither指的是一个都不。
翻译：他们看起来不太喜欢彼此。他们也都不怎么喜欢传统的人。
3.Down came the white only notices in buses, hotels, trains, restaurants, sporting events, rest rooms and on park benches that once could be found everywhere throughout the South.
结构：全句有2个谓语动词：came，could be.其中主句的是：came.按照正常语序句子主干应该是：The white only notices came down. Notices后面的介词短语，作为后置定语修饰notices.介词短语后面还有一个that引导的定语从句修饰notices.为了避免主语部分过于冗长，因而将主谓倒装。
