The traditional rule requires thatnor be used following neither in expressions in which the negation is carried over to the second element:He is neither able nor (not or ) willing to go. Noris likewise required when a negation is carried over into the second of two independent clauses, in which caseit also triggers inversion of the subject and the auxiliary verb in the second clause:
传统规则要求nor 用于 neither 后面， 在这种表达中，否定放在第二个部分：他既不能也 （不用 or ) 不愿走。 Nor在当两个独立句子中的第二个也被否时被用， 在这种用法中，它也引起第二个句子主语和助动词的转变：
例句：
He cannot find anyone now, nor does he expect to find anyone in the future;
现在他找不到任何人，以后也别梦想找到任何人 ；

例句：
Jane will never compromise with Bill, nor will Bill compromise with Jane.
简决不会同比尔和解，而比尔也决不会同简和解。

When the first negative is expressed bynot or never, however, and when the second conjoined element is a verb phrase,the use ofnor is often optional:
然而当第一个否定词用not 或 never 表达， 且当第二个连结部分是动词短语时，nor 的用法通常可选择：
例句：
He will not permit the change, or (or nor ) even consider it.
他决不会容许改变，或者（或者用 nor ） 甚至考虑它。
