both, either, neither用法各不同

both, either, neither这三个词都能够作代词及形容词,在考试中几回亮相,许多同窗都容易将他们混淆,现将它们的用法归纳如下,让大伙儿看个明白,轻轻松松把握它们的词义、词性及用法。

简表说明:

一、Both用法浅谈

Both可作形容词、代词或副词用,意思是“两个”、“两边”、“两个都”。在句中可作主语、宾语或同位语。

如:Both are right.二者都对。(主语) I like both.两个我都喜爱。(宾语)

Both可参与组成名词词组,也可和动词连用,还可与and组成并列连词。在使历时,要注意以下几点:

一、Both和both of后都可接复数名词,组成名词词组。但Both后的名词前可有定冠词、指示代词或物主代词作修饰限定,也可没有;both of后的名词前却必然要有定冠词、指示代词或物主代词作修饰限定。

如:能够说both(the these,her) children;也能够说both of the(these,her)children;但一样不说both of children。

Both of后可接人称代词宾格,both后那么不可;但人称代词宾格后可接both。能够说both

of us(you,them),一样不说both us(you,them),但能够说us(you,them)both。

二、Both与动词连历时,大多数放在系动词be以后,其它动词之前。

如:His parents are both workers. They both enjoy reading.

3、Both可与and组成并列连词,连接两个性质相同并在句中作相同成份的并行结构。

如:Both he and his brother are good at English. (连接两个主语)

She can both dance and sing. (连接两个谓语动词)

Mary is both kind and beautiful. (连接两个表语) 4、含both的句子变成否按时,是将both改成neither。

如:当确信句为Both of the boys are clever.(两个男孩都伶俐)时,否定句当为Neither of

the boys are clever.(两个男孩都不伶俐)。Both后接复数名词,neither后接单数名词,动词的人称和数也要随之转变。假设把句子变成Both of the boys are not clever,那么是不完全否定。意思是:并非是两个男孩都伶俐(一个伶俐一个愚笨)。

五、含both…and…的句子变成否定句时,将both…and…改成neither…nor..,连接的两个部份假设是名词,能够是单数,也能够是复数。

如:I know both the man and the woman. 我既熟悉那男子,也熟悉那妇女。

说明:作为关联并列连词,它通常应连接两个相同性质的句子成份,但有时后一成份可能省略与前一成份相同的词。另外,假设连接两个成份作主语,谓语老是用复数。如:

Both she and I are good at English. 她和我都擅长英语。

Both teaching and research work are making great strides. 教学与科研都在大踏步前进。

二、either...or...

...or...意为"或……或……;不是……确实是……"之意。表示二者之一,连接句子中两个并列的成份。例如:

When the girl is happy, she either sings or dances. 那个女孩快乐时,不是唱确实是跳。(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维持一致,这确实是咱们通常说的"就近原那么"。例如:

Either you or I am going there tomorrow. 明天要么你去那里,要么我去那里。

2.注意:假设是把上句变成一样疑问句,助动词形式与主语you维持一致,因此要用are提问,而不是am。例如:

Are either you or I going there tomorrow? 明天是你仍是我去那里? Either you or he has lunch at school. 其一样疑问句应为:Do either you or he have

lunch at school? 是你仍是他在学校吃午饭?

3. 假设要对either...or...句型进行否按时,只需把either...or...换成neither...nor...即可。例如:

Either you or she is good at drawing. 变成否定句应为:Neither you nor she is

good at drawing. 你和她都不擅长绘画。

4. 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. 假设是你不去那里,我也不去。

三、neither...nor...

1. neither...nor...表示"既不……也不……"。其含义是不是定的,可连接任意两个并列的成份。例如:

She likes neither butter nor cheese. 她既不喜爱黄油也不喜爱乳酪。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"就近原那么"。例如:

Neither dad nor mum is at home today. 今天父母都不在家。

2.假设将neither...nor...句型变成确信句,只需把neither...nor...改成both...and...即可,同时谓语动词必需用复数形式。例如:

Both dad and mum are at home today. 今天父母都在家。

还能够单独利用neither作主语,表示"二者中没有一个"。例如:

Neither of them likes football. 他们俩都不喜爱足球。

3. neither或nor还有另外一种用法,确实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,咱们也没去。

四 、either of ,neither of, both of 和all of 的用法

先来一个总结,再给例子 :either of (二者其一) ;neither of(二者都不)

这两个后+单数 ;both of (二者都),后+复数 ;all of (三者或三者以上都是) none of (三者或三者以上都不是)

of 是指“二者有其一......” Either of us speaks English. (注意“speaks“)

of是指“二者都不...” 用于否定句 Neither of us speaks English. (注意“speaks“)

both of是指二者都...... 用于确信句 Both the boys are clever. 两个男孩都很伶俐。

of与both of 注意区别二者的意思,不同的意思,单复数不一样.

① There are two apples on the table; you can take either of them. 桌上有两只苹果,随你拿哪一只。

② There are two apples on the table; you can take both of them. 桌上有两只苹果,你能够把两只都拿去。

③ There are trees on either side of the street. 街的两边(每一边)绿树成荫。

④ There are trees on both sides of the street. 街的两边绿树成荫。

of是指所有人(或物)都...(超过两个)

All of the Chinese students are Young Pioneers.所有中国学生都是少先队员。

否定式:Not all of,意思是“不尽是” (万万不要误以为是“全数都不是”。)

Not all of us went to school yesterday.昨天咱们不全都来上学。

对照:All of us went to school yesterday.昨天咱们全都来上学.

of 是指“所有人(或物)都不...”全数否定(超过三个)

以None of 开头的句子,谓语动词用单数或复数都可。

None of ...作主语,强调个体时,谓语动词用单数;假设强调整体时,谓语动词那么用复数。 None of us speaks English. (注意“speaks“)

He likes none of these books.这些书他一本也不喜爱

None of the money is mine. 这笔钱没有一点是我的.

None of these cars is [are] new.这些汽车没有一辆是新的.
