neither
1.neither在用作代词或形容词的时候，用于两个人或物。例如：I have two dictionaries, but neither is here. 和I have two dictionaries, but neither book is here. 有时也用于两个以上。例如：I have three dictionaries, but neither is here. 和I have three dictionaries, but neither book is here. 但这种用法不算正当，该避免，该改用none。
但neither（副词或连接词）...nor...用于两个以上可以算得正当。例如：Neither you, (nor) your brother, nor your sister will do.
2.注意In neither case can I agree里用can I，不用I can。
3.neither（代词或形容词）属于单数形式，如Neither is good和Neither book is good。把它当作复数是英美人常有的错误。
4.注意下面各句里的动词：
- Neither he nor you are wrong.
- Neither you nor he is wrong.
- Neither the father nor the sons are wrong.
- Neither the sons nor the father is wrong.
但这种结构一般避免使用，如上面四句可以改作：
- He is not wrong, nor are you.
- You are not wrong, nor is he.
- The father is not wrong, nor are the sons.
- The sons are not wrong, nor is the father.
5.neither...nor...跟both...and...受同样的规则的限制，如可以说neither boys nor girls，也可以说neither with boys nor with girls和with neither boys nor girls，但不可说neither with boys nor girls。参见both 4和either 7
6.注意下面两句里用is he，are you，has he和will he，不用he is，you are，he has和he will：
- Neither is he wrong nor are you.
- Neither has he heard from her yet nor will he do so before long.
7.neither...nor...里的nor决不可改作or。
8.neither用作nor。例如：He is not wrong, neither are you. 前面也可以有and或but。例如：He is not wrong, and neither are you. 和He is not wrong, but neither are you.
9.可以说If he is not wrong, neither are you。
10.下面B说Neither he is而不说Neither is he，因为he就是A所说的he，说Neither is his brother而不说Neither his brother is，因为his brother并不就是he：
A: I don't think he is clever.
B: Neither he is. Neither is his brother.
11.I don't know that neither和He did not give me a single yuan, nor a single fen neither等句子里的neither是副词，现在不很普通，通常用either。参见either 8
