neither...nor怎么用?
neither...nor怎么用?

neither...nor怎么用?
either...or...与 neither...nor...
一、either...or...
either...or...意为"或者……或者……;不是……就是……"之意.表示两者之一,连接句子中两个并列的成分.例如:
When the girl is happy,she either sings or dances.那个女孩高兴时,不是唱就是跳.(此句中either...or...连接两个动词,因为主语是单数第三人称,谓语动词要用其相应的形式.)
either...or...连接两个主语时,其谓语动词应与最近的一个主语在人称和数上保持一致,这就是我们通常说的"就近原则".例如:
Either you or I am going there tomorrow.明天要么你去那里,要么我去那里.
注意:如果把上句变成一般疑问句,助动词形式与主语you保持一致,所以要用are提问,而不是am.例如:
Are either you or I going there tomorrow?明天是你还是我去那里?
Either you or he has lunch at school.其一般疑问句应为:Do either you or he have lunch at school?是你还是他在学校吃午饭?
若要对either...or...句型进行否定时,只需把either...or...换成neither...nor...即可.例如:
Either you or she is good at drawing.变为否定句应为:Neither you nor she is good at drawing.你和她都不擅长绘画.
我们还可以单独使用either,其意为"两者中的任何一个".例如:
There are many shops on either side of the street.街道两边有许多商店.这个句子也可以这样表达:There are many shops on both sides of the street.在街道两边有许多商店.
either用在否定句的句末,表示"也"的意思.例如:
If you don\'t go there.I won\'t,either.如果你不去那里,我也不去.
二、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.

用于否定句,可以说是Both……and的反义词
For example:Neither you nor me is a student.=Both you and me are not students.

用于否定句
既不...也不...
