谁能具体讲一下neither、、、nor和either、、、or的用法多举几个例子,

楼上的说的很好,但是注意当他们在主语中,注意谓语的就近原则,这是考试中长考的

neither...nor... 既不……也不……
Neither he nor I know.他和我都不知道。
either...or... 或者...或者..., 不论...还是...
Either you come in person, or you entrust someone with the matter. 你要么自己来,要么就托人办理这件事。

neither...nor是既不..又不.e.g.i am neither hungry nor thirsty.我既不渴也不饿.e.g.——which one do you prefer,orange or apple?你喜欢哪一个?苹果还是橘子?——neither (of them).i like pears.都不喜欢.我喜...

neither/nor:两者都不...
either...or:两者之一,或者...或者...
either用于否定句中,表示"也".如
I don't like dancing,he doesn't like it either.
both and: 两者都...
举几个例子:
1.Neither of us can speak Japanese.
2.I can't speak Japanese.Neither/Nor can him.
3.I don't know what language he knows,either English or Japanese.
4.He can speak both English and Japanese.
