1.neither ...nor ...就近一直原则(在如not..but...;either..or ...：not only..but also...)
Neither I nor he is right
Neither Jim nor his parents are here.
2.every A and every B
each A and each B
many a A and many a B
以上三个短语做主语时,谓语动词用单数.
Every boy and (every)girl has a wonderful tool.
Many a boy and many a girl is singing.
需要指出的一点是:几个网友说的与B一致是不严密的.一般情况下是这样的,极少数的情况下为疑问句时就和A一致.所以说就近一致.
