这句话的语法结构是什么?
It would have been entirely unremarkable had it not been full to the brim with dancing blue-white flames.来自 哈利波特与火焰杯 第十六章

Answer 1

这是个含有与过去事实相反的虚拟条件句,由于条件句中的if 省略了,所以将从句中的had助动词提前,用了倒装语序.这个句子的正常语序是：
It would have been entirely unremarkable it hd not been full to the brim with dancing blue-white flames
或者
If it hd not been full to the brim with dancing blue-white flames,it would have been entirely unremarkable
再比如：
Were it to rain tomorrow,we would put off the sports meet.
Should it rain tomorrow,we would put off the sports meet.
虚拟句中可以倒装的就这三个词had,were和should
PS:1.你任意百度一下虚拟语气,即可见到这种用法（在虚拟条件句中找这个相关内容）：
2.也可以百度倒装句语法,一样能找到这样的结构.
