问题：关于否定意义的副词提前的倒装句,谢谢您的回答!1:neverwo 
1: never would he know what she had suffer.2: Hardly had John arrived home when he beganhis homework.3: seldom have I seen such brutality.问题1: 这3句话中的would had have是情态动词吗? 如果还原这3句话, 是不是这几个情态动词都该在never, hardly和seldom的前面呢? 当否定意义的副词提前的, 必须把情态动词提前且放到在副词的后面吗?never before1: never would he know what she had suffer.2: Hardly had John arrived home when he beganhis homework.3: seldom have I seen such brutality.问题1: 这3句话中的would had have是情态动词吗? 如果还原这3句话, 是不是这几个情态动词都该在never, hardly和seldom的前面呢? 当否定意义的副词提前的, 必须把情态动词提前且放到在副词的后面吗?never before has such a high standard been achieved.问题2: 还原后是不是Such a high standard has never been achieved before? 倒装的语序是必须把before提前到never的后面和情态动词has的前面吗?这里的has是助动词吗?before是状语吗?不好意思, 才疏学浅, 让您见笑了. 谢谢您的耐心解答, 我会尽快采纳答案的!
回答：1、（1）would、had、have可以看作助动词，would构成过去将来时、had构成过去完成时、have构成现在完成时。（2）还原时这几个词在副词前是因为副词在句中的位置决定的：副词位于句中时通常放在第一个助动词之后；如果没有助动词时一般放在行为动词前。（3）否定意义的副词在句子开头时句子要部分倒装，那么副词一定在前面就不用说了；部分倒装的方法简单说就是初中学习的变一般疑问句的方法：把系动词或助动词提前。这样一来，你的第三个问题就不言自明了吧。
2、还原后的句子就是你的句子；倒装时的另一种说法：Never has such a high stardard been achieved before.倒装的关键是never这个否定副词必须开头，before只是个时间状语，不一定非得提前。原句before提前是因为强调这个时间状语。has是构成现在完成时的助动词。
