Neither用法
1.neither做adv.“也不”，放句首用倒装结构：neither+be 动词/助动词/情态动词+主语，表示前面否定的内容也适用于另外一个人或物，意为“....也不”
Eg. ----She didn’t go to school.----Neither did Tom.
Tom is not good at math and neither is Jack
Jack can’t draw and neither can Peter.
与上述结构相反的用法是，so+be动词/助动词/情态动词+主语,表示前面肯定的内容也适用于另外一个人或物，意为“....也是，....也一样”
Eg. My father likes swimming and so do I.
I will study harder and so will my brother.
2.Neither做pron,”两者都不”，作主语时谓语通常用单数；其反义词是both（两者都），作主语谓语用复数
Eg. Neither of my parents is at home.
Neither answer is right.
Both of them are strong in English.
3.Neither....nor...既不。。。也不。。。，either。。。Or。。。。要么。。要么。。。，或者。。或者。。。
这两个短语连接并列主语时，谓语动词遵循就近原则。
Neither he nor you are right.
Either you or I am right.
