例句：Neither of the books is interesting．I won't buy either of them
这两本书都不吸引人，我不会买其中的任何一个．
neither意思是"两者都不"
neither of 后面跟复数名词时，谓语动词要用单数either意思是"两者之中的任何一个"．又根据"I won't buy ________ of them"由于两者都不吸引人，我不会买这两本书中的任何一本．
neither of.作主语谓语动词必须用单数.
如：Neither of them is right.
both... and...作主语谓语动词必须用复数
如：Both Lily and Lucy are students.
类似的还有either...or...， not only ... but also...这两个作主语时谓语动词的单复数由第二个主语来决定.

Not only you but also he is a student
