neither和either的区别
1) either指两者中的任何一个，neither指两者都不。作代词时，either, neither一般接单数动词。作限定词时，一般加单数名词。
【例如】
Either of them will be appointed Minister of Finance.Neither of the two speaks English well.You must not favor either side in the dispute.In neither case can I agree with you.
2) either...or表示两个或多个选择中的一项。neither...nor表示“既不，也不”。either...or, neither...nor连接的两个名词或代词作主语时，谓语动词与最靠近它的主语一致。
【例如】
He neither knows nor cares what has happened.Neither he nor I have met such a beautiful girl before.He must be either mad or drunk.Either she or you are to be blamed for what has happened.
3) either表示也不，用于否定句。(too表示“也”，用于肯定句。)
【例如】
I don't like the yellow shirt, I don't like the green one, either.
4) neither可以引导倒装句，表示和前面的情况一致，而且前面为否定句。
【例如】
The organization had broken no rules, but______had it acted responsibly. (CET-4 1996,1)A) neither B) so C) either D) bothneither引导倒装句，表示和前面的否定情况一致。so引导倒装句，表示和前面的肯定情况一致。either表示两者中的一个，both表示两者都。答案为A.
