neither.nor,either.or,not only ...but.also的用法

neither.nor,either.or,not only ...but.also的用法
连词
1.并列连词.
①both … and, either … or, neither … nor
both … and“双方都”,连接句子的两个主语时,其后谓语动词通常用使用复数形式.either … or与neither … nor注意采取“就近原则”.
②not only … but also, as well as
注意:两者强调对象不同,not only … but also强调的是but also之后部分,而as well as则强调其前面的部分.not only … but also采取“就近原则”,而as well as只是一个插入语,采取“就远原则”.如:
Mr.Smith, as well as his wife and children, has come to Nanjing for a visit.
not only … but also结构中的not only可用于句首,连接两个分句时,第一个从句主谓要倒装.
Not only is he clever ,but also he is hard working.
2.从属连词.
①when、while、as都表示“当……时候”,when引导的从句的动作与主句的动词可同时发生,也可先后发生;
as、while引导的从句则强调主句和从句的动作同时发生.如:
When I go to the station, the train had already left.
He sang merrily as he was working.
②till、until均表示“到……时候止”,肯定句中的谓语必须是延续性动作.如:I worked till late at
night.若主句谓语是终止性动词,则主句要用否定形式,意为动作“到……才……”开始发生.如:
She didn’t get up until her mother came in.
注意:till和until通常情况下可以互换,只是在句首时until比till更常用.
③though、although均引导让步状语从句,意为“虽然……”,although较正式,though最常用.如:
Thouth (Although)he was tired,he kept on working.
注意:though、although引导的从句不能与but、however连用,但可以与yet、still连用.though还可以与别的词结合使用,如even though、
as though,而although则不能这样搭配.
④no sooner … than、hardly … when、as soon as三者都表示“一……就”,“刚刚……就”的意思.(A)as soon as 置于主句前后都可以,而且有备各种时态.如:As soon as she gets here I’ll tell her about
it. Mary left as soon as the finished the work.(B)hardly … when、no sooner … than不能表示将来的事,其主句的谓语动词一般用过去完成时,从句用过去时.若将hardly或no sooner放在句首,句子要倒装.如:No
sooner had he arrived than he went away again.
⑤某些表示时间的名词(词组)也可用作从属连词.它们是:the moment, the minute,the instant, the day, the time, the first(second, third …)time, the spring (summer, autumn,winter),every(each,next,
any) time(day),by the time,都可引导时间状语从句.如:
His mother died the spring he returned.
Call me up the minute he arrives.

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。
