的用法
用于连接两个表示选择关系的名词或代词,意为
“
要么
……
要么
”
.如：
He must be either mad or drunk.
他不是疯了就是醉了.
You can go swimming or play tennis.
你可以去游泳也可以去打网球.
Either you or I am wrong.
不是你错了就是我错了.
Are either you or I wrong?
是你错了还是我错了
说明：通常应连接两个相同性质的句子成分,但有时后一成分可能省略与前一成分相同的词.若连接两
个成分作主语,其谓语通常与靠近的主语保持一致.如：
You can either have tea or coffee.
你喝茶也行,喝咖啡也行.
Either you or I am wrong.
不是你错,就是我错.
neither……nor……
neither……nor……表示"既不……也不……".其含义是否定的,可连接任意两个并列的成份.例如：
She likes neither butter nor cheese.她既不喜欢黄油也不喜欢乳酪.此句中neither……nor……连接两个宾语.当neither……nor……连接两个主语时,也应遵循"就近原则".例如：
Neither dad nor mum is at home today.今天父母都不在家.
若将neither……nor……句型变为肯定句,只需把neither……nor……改为both……and……即可,同时谓语动词必须用复数形式.例如：
Both dad and mum are at home today.今天父母都在家.
还可以单独使用neither作主语,表示"两者中没有一个".例如：
Neither of them likes football.他们俩都不喜欢足球.
neither或nor还有另外一种用法,就是当表达一个人没有做某事,另一个人也没做同一类事时,可用neither或nor进行简略回答,其结构为：Neither / Nor+助动词 / 情态动词 / be动词+主语.例如：
He doesn\'t go to school by bike.Neither / Nor do I.他不是骑自行车上学,我也不是.
They didn\'t go to the park yesterday.Neither / Nor did we.昨天他们没去公园,我们也没去.

Joy has been to neither Korea nor Japan.
