一个英语部分倒装句.大家帮下忙.

"Never before I such a wonderful feast."
" seen" 动词的拼写(过去完成时)不应改 "see" ,因为前面有 "had' 助动词.
其他例句(倒装句):
(1) "Never before had taxpayers so many changes at once as they had in the Tax Reform Act ."
(2) The most obvious reason for the high,86% voter turnout was that the black
majority had never before a chance to vote,
(3) Never before have so many voters fallen into that category and never before had
so many of them 过去完成时 Democratic...

这是部分倒装 否定词开头的句子用部分倒装。had seen是过去完成时，其中的had为助动词。部分倒装只用把助动词提前。要是原来时态为一般过去时，且谓语动词为行为动词这时候倒装则要借助于助动词 did +主语+原来谓语动词的动词原型。例如：Hardly did he eat this morning....

had done结构不变
