英语中1又4分之一等大于1小于2个物体做主语,谓语动词用单数还是复数?分数做主语时

one.做主语时,谓语动词是单数还是复数

意为“一个人\其中一个”时,one为名词,可做主语谓语动词用单数:There are 2 children in the yard.One is running , and the other one is chasing behind him.因为主谓语单复数形式要一致

而one作数词修饰名词时就另当别论,路more than one+单\复数名词,需要的话我会进行补充

那些单词作主语谓语动词用单数?

谓语动词为单数,那么根据主谓一致原则,主语必为单数或不可数。于是,单数第一人称I、单数第三人称he/she/it、可数名词单数以及不可数名词作主语,谓语动词用单数。

啥作主语谓语动词用单数

英语语法--主谓一致

主谓一致是指:

1) 语法形式上要一致,即单复数形式与谓语要一致。

2) 意义上要一致,即主语意义上的单复数要与谓语的单复数形式一致。

3) 就近原则,即谓语动词的单复形式取决于最靠近它的词语,

一般来说,不可数名词用动词单数,可数名词复数用动词复数。

There is much water in the thermos.

但当不可数名词前有表示数量的复数名词时,谓语动词用复数形式。

Ten thousand tons of coal were produced last year.

1 并列结构作主语时谓语用复数

Reading and writing are very important.

注意: 当主语由and连结时,如果它表示一个单一的概念,即指同一人或同一物时,谓语动词用单数,and 此时连接的两个词前只有一个冠词。

The iron and steel industry is very important to our life.

典型例题

The League secretary and monitor ___ asked to make a speech at the meeting.

A. is B. was C. are D. were

答案B. 注: 先从时态上考虑。这是过去发生的事情应用过去时,先排除A.,C.。本题易误选D,因为The

League secretary and monitor 好象是两个人,但仔细辨别, monitor 前没有the,在英语中,当一人兼数职时只在第一个职务前加定冠词。后面的职务用and 相连。这样本题主语为一个人,所以应选B。

2 主谓一致中的靠近原则

1)当there be 句型的主语是一系列事物时,谓语应与最邻近的主语保持一致。

There is a pen, a knife and several books on the desk..

There are twenty boy-students and twenty-three girl-students in the class.

2)当either… or… 与neither… nor, 连接两个主语时,谓语动词与最邻近的主语保持一致。 如果句子是由here, there引导,而主语又不止一个时,谓语通常也和最邻近的主语一致。

Either you or she is to go.

Here is a pen, a few envelops and some paper for you.

3 谓语动词与前面的主语一致

当主语后面跟有with, together with, like, except, but, no less than, as well as 等词引起的短语时,谓语动词与前面的主语一致。

The teacher together with some students is visiting the factory.

He as well as I wants to go boating.

4 谓语需用单数

1) 代词each和由every, some, no, any等构成的复合代词作主语,或主语中含有each, every, 谓语需用单数。

Each of us has a tape-recorder.

There is something wrong with my watch.

2) 当主语是一本书或一条格言时,谓语动词常用单数。

The Arabian Night is a book known to lovers of English.

<<天方夜谭>>是英语爱好者熟悉的一本好书。

3) 表示金钱,时间,价格或度量衡的复合名词作主语 时,通常把这些名词看作一个整体,谓语一般用单数。(用复数也可,意思不变。)

Three weeks was allowed for making the necessary preparations.

Ten yuan is enough.

5 指代意义决定谓语的单复数

1) 在代词what, which, who, none, some, any, more, most, all等词的单复数由其指代的词的单复数决定。

All is right. (一切顺利。)

All are present. (所有人都到齐了。)

2) 集体名词作主语时,谓语的数要根据主语的意思来决定。如family, audience, crew, crowd, class,

company, committee等词后用复数形式时,意为这个集体中的各个成员,用单数时表示该个集体。

His family isn't very large. 他家不是一个大家庭。

His family are music lovers. 他的家人都是音乐爱好者。

但集合名词people, police, cattle, poultry等在任何情况下都用复数形式。

Are there any police around?

3)有些名词,如variety, number, population, proportion, majority 等有时看作单数,有时看作复数。

A number of +名词复数+复数动词。

The number of +名词复数+单数动词。

A number of books have lent out.

The majority of the students like English.

6 与后接名词或代词保持一致

1) 用half of, part of, most of, a portion of 等词引起主语时,动词通常与of后面的名词,代词保持一致。

Most of his money is spent on books.

Most of the students are taking an active part in sports.

2) 在一些短语,如 many a 或 more than one 所修饰的词作主语时,谓语动词多用单数形式。但由

more than… of 作主语时,动词应与其后的名词或代词保持一致。

Many a person has read the novel. 许多人都读过这本书。

四分之一的英文可以是one-fourth吗 为什么又可以是a quarter是不是分数也有很多种表达方法的吖

嗯,可以这么用,只是四分之一啊,百分之一啊之类的有特殊说法,其余见下:

语分数的表示法:

一、用“基数词+序数词”表示

分数在英语中通常是借助于基数词和序数词来共同表达的。其中基数词表示分子,序数词表示分母。

如:

1.The centimeter is one-tenth of the decimeter or one-hundredth of the meter.厘米是分米的十分之一,或者说是米的百分之一。

2.However,the number of boys will bea third or less than the girls in the class.但是,班里男生的人数将比女生少三分之一或更少。

从以上例子可以看出:分子除用one外,也可用a;如果分子大于1,分母要用复数形式。但是,1/2不能说a(one)second,而要说a(one)half。例如:

3.The sum of one half,one third and one fourth of a certain number is 13.某数的1/2,1/3和1/4的和是13。

1/4和3/4可以说a(one)fourth和three fourths,但常用a quarter和three quarters表示。应该注意的是,分数修饰名词时,若该名词是不可数名词只能用单数;若是可数名词,用单数或复数均可。但是,若它们在句子中作主语,则谓语动词是用单数还是复数取决于名词,即与分数所修饰的名词保持一致。例如:

4.Only one-fifth of air consists of oxygen.氧气只占空气的1/5。

5.About two thirds of the students attendthe meeting.大约2/3的学生都参加了会议。

带分数也是常见的英语数词表达。所谓带分数,实际上是“整数+分数”,表达时分而述之,只是整数部分与分数部分要用连词 and连接。当带分数修饰名词时,该名词通常是复数,但若名词置于整数one或a之后,则用单数。“带分数+名词”作主语时,谓语动词根据临近原则要用复数。例如:

6.You should finish the work within one and a fourth hours.你应在1.25小时内完成工作。

7.The atom breaks up in a minute and a quarter.原子在1.25分钟内裂变。

二、用per cent等表示

表示百分之一可以说one(a)hundredth,但更常用one percent或per cent,即用百分数表示法来表达。例如:

8.Our bodies are 65percent water.我们人体含65%水分。

9.Seventy-five percent of the earth'ssur- face is covered by water.地球表面的75%被水覆盖着。

10.Eighty-five percent of the students in English department are girls.英语系85%的学生是女生。
