nor
1.注意下面各句里用is she，does he和must we，不用she is，he does和we must：
- He is not unkind to her, nor is she to him.
- He does not do it, nor does he try to.
- All that is true, nor must we forget about it.
nor前面也可以有and。例如：
- You cannot do that, and nor can I.
- I didn't see it, and nor did you.
但and nor远不及nor普通。
偶尔在nor前面用but。例如：I didn't see it, but nor did you.
2.He can neither read nor write里当然用nor，不可用or，He cannot either read or write里当然用or，不可用nor。He cannot read (n)or wirte里用or或nor都可以，现在用or比用nor普通。但He cannot read, nor write （read后面有逗号）和He does not ride, nor shoot, nor fish, nor swim （ride，shoot和fish后面都有逗号）里的nor都不可改作or。注意下面每组里的两句：
- Jack had no tea or coffee.(没有逗号)
Jack had no tea,nor coffee.(有逗号) - He has never heard of her or of her sister.(没有逗号)
He has never heard of her, nor of her sister.(有逗号)
“他不曾去，也不会去”可以说He did not go，nor will be或He did not come and will not，不可说He did not come or will not。
3.下面B说Nor he is而不说Nor is he，因为he就是A所说的he，说Nor is his brother而不说Nor his brother is，因为his brother并不就是he：
A: I don't think he is clever.
B: Nor he is. Nor is his brother.
