1.Both (the)instruments are valuable to this process.(定语)这两个仪器对这个过程都是很有价值的.

2.Both (the)student have made a good few experiments on electricity.(定语)这两个学生都做了不少电学实验.

二、代词both作“两人”、“两者”

4.He and I are both from Tianjin.(both作同位语.注意both在本句中的词序和上两句不同.)他和我都是天津人.

三、“both…and…”起连接词作用,作“两者都”、“又……又”、“不但……而且”

注意:“both…and…”能连接各种并列成分,甚至两个句子.

1.Both copper and silver are good conductors of electricity.(连接两个主语)铜和银都是良好的电导体.

2.Both of the books are not helpful.这两本书并非都是有益的.

如果要将上述两句改成全部否定,则就应写成:

2.Neither of the books is helpful.(=Eit

her of the books is not helpful.=Either

neither、either、both的用法区别

一、neither、either、both的用法

1、Neither的用法

1)代词。意为“两者中任何一方都不”both的反义词,作主语时谓语动词用单数。

Neither of the books is mine.

这两本书没有一本是我的。

2)形容词。修饰名词时,名词使用单数。

Neither boy can swim.

两个男孩都不会游泳。

3)连词。Neither与nor连用:neither—nor— 意为“既不——也不——”连接两个并列的句子成分(连接主语时,谓语动词就近选择)

Neither he nor I am a teacher.

他和我都不是老师。

2、Either的用法

1)代词。意为“两者中的任何一个”谓语动词用单数。

Either of us is a student.

2)形容词。修饰名词时,名次使用单数。

Either boy can swim.

两个男孩中有一个会游泳。

3)连词。与or连用:either…or….意为“不是—就是—,要么—要么—,或者—或者—”连接两个并列的句子成分(连接主语时,谓语动词就近选择)用在否定句中和意思与neither nor 一样。

Either you or I am wrong.不是你错了就是我错了。

He doesn't know Germen or French.=He knows neither German nor French.

3、Both的用法

1)代词。意为“两者都”和谓语动词连用时,放在行为动词前,语法词之后。与of 连用作主语时,谓语动词用复数。

We must both study English well.

Both of us are from America.=We are both Americans.

2)形容词。修饰名词时,名次使用单数。

There are many trees on the both sides of the road.

3)连词。both and连用。意为“——两者都——”连接主语时谓语动词用复数。

Both my brother and I are football players.

这些词都可用作代词或形容词。其位置都在be 动词之后,行为动词之前或第一助动词之后。

二、neither、either、both的区别

neither、either、both的区别有以下几种情况:

1、 both (两者都),either(两者中任何一个), neither (两者都不)。以上词使用范围为两个人或物。

Neither of the two boys is clever. 两个男孩都不聪明。

2、both,either

both与复数连用,either与单数连用。

Both the boys are clever. 两个男孩都很聪明。

Either of the two boys is clever. 两个男孩都很聪明。

There are flowers on both sides of the street.(两岸)

There are flowers on either side of the street.(岸的两边)

路边长满了野花。

3、either指两者中的任何一个,neither指两者都不。作代词时,either, neither一般接单数动词。作限定词时,一般加单数名词。

例:

Either of them will be appointed Minister of Finance.Neither of the two speaks English well.You must not favor either side in the dispute.In neither case can I agree with you.

4、either…or表示两个或多个选择中的一项。neither…nor表示“既不,也不”。either…or, neither…nor连接的两个名词或代词作主语时,谓语动词与最靠近它的主语一致。

例:

He neither knows nor cares what has happened.Neither he nor I have met such a beautiful girl before.He must be either mad or drunk.Either she or you are to be blamed for what has happened.

5、either表示也不,用于否定句。(too表示“也”,用于肯定句。)

例:

I don't like the yellow shirt, I don't like the green one, either.

6、neither可以引导倒装句,表示和前面的情况一致,而且前面为否定句。

例:

The organization had broken no rules, but______had it acted responsibly.

A) neither

B) so

C) either

D) both

neither引导倒装句,表示和前面的否定情况一致。so引导倒装句,表示和前面的肯定情况一致。either表示两者中的一个,both表示两者都。答案为A.

Neither nor的用法及就近原则

一、Neither nor的用法

具体Neither nor的用法有以下几种:

1、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。

2、当neither…nor…连接两个主语时,也应遵循"Neither nor就近原则"。例如:

Neither dad nor mum is at home today.

今天父母都不在家。

3、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。

4、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。

二、Neither nor就近原则

Neither nor就近原则的知识点称为主谓一致

主谓一致分为两大类:就近一致原则和意义一致原则.

就近一致原则指的是,以靠近谓语动词的,作主语的名词作为人称和数的参考标准.

不仅仅是Nether nor遵循就近原则,其他连词比如:not only…but also/ or/ either…or/ not…but都遵循就近原则。

例如:

Neither he nor they are wholly right.

他和他们,谁都不是完全对的

Not only the students but also the teacher is enjoying the film.

不仅学生而且老师都在津津乐道地看着电影.

Neither the students nor the teacher knows anything about it.

同学们和老师对此都一无所知.

Either he or I am right.
