主谓一致

语法复习二、主谓一致

在英语句子里,谓语受主语支配,其动词必须和主语在人称和数上保持一致,这就叫主谓一致。寻其规律,大致可归纳为三个原则,即语法一致、逻辑意义一致和就近一致原则。

(一)语法一致原则:语法上一致就是谓语动词和主语在单、复数形式上保持一致。

1、以单数名词或代词、动词不定式短语、动名词短语或从句作主语时,谓语动词一般用单数形式;主语为复数时,谓语动词用复数形式。如:His father is working on the farm. / To study English well is not easy. / What he said is very important for us all. / The children were in the classroom two hours ago. / Reading in the sun is bad for your eyes.

注意:由what引导的主语从句,后面的谓语动词多数情况用单数形式,但若表语是复数或what从句是一个带有复数意义的并列结构时,主句的谓语动词用复数形式。如:What I bought were three English books. / What I say and do is (are) helpful to you.

2、由连接词and或both ? and连接起来的合成主语后面,要用复数形式的谓语动词。如:Lucy and Lily are twins. / She and I are classmates. / The boy and the girl were surprised when they heard the news. / Both she and he are Young Pioneers.

注意:① 若and所连接的两个词是指同一个人或物时,它后面的谓语动词就应用单数形式。如:The writer and artist has come.; / ② 由and连接的并列单数主语前如果分别有no, each, every more than a (an) , many a (an)修饰时,其谓语动词要用单数形式。如:Every student and every teacher was in the room.. / No boy and no girl likes it.

3、主语为单数名词或代词,尽管后面跟有with, together with, except, but, like, as well as, rather than, more than, no less than, besides, including等引起的短语,谓语动词仍用单数形式;若主语为复数,谓语用复数形式。如:Mr Green, together with his wife and children, has come to China. / Nobody but Jim and Mike was on the playground. / She, like you and Tom, is very tall.

4、either, neither, each, every 或no +单数名词和由some, any, no, every构成的复合不定代词,都作单数看待。如:Each of us has a new book. / Everything around us is matter.

注意:① 在口语中当either或neither后跟有"of+复数名词(或代词)"作主语时,其谓语动词也可用复数。如:Neither of the texts is (are) interesting. ② 若none of后面的名词是不可数名词,它的谓语动词就要用单数;若它后面的名词是复数,它的谓语动词用单数或复数都可以。如:None of us has (have) been to America.

5、在定语从句时,关系代词that, who, which等作主语时,其谓语动词的数应与句中先行词的数一致。如:He is one of my friends who are working hard. / He is the only one of my friends who is working hard.

6、如果集体名词指的是整个集体,它的谓语动词用单数;如果它指集体的成员,其谓语动词就用复数形式。这些词有family, class, crowd, committee, population, audience等。如:Class Four is on the third floor. / Class Four are unable to agree upon a monitor.

注意:people, police, cattle等名词一般都用作复数。如:The police are looking for the lost child.

7、由"a lot of, lots of, plenty of, the rest of, the majority of + 名词"构成的短语以及由"分数或百分数+名词"构成的短语作主语,其谓语动词的数要根据短语中后面名词的数而定。如:There are a lot of people in the classroom. / The rest of the lecture is wonderful. / 50% of the students in our class are girls.

注意: a number of"许多",作定语修饰复数名词,谓语用复数;the number of"?的数量",主语是number,谓语用单数。

8、在倒装句中,谓语动词的数应与其后的主语一致。如:There comes the bus./ On the wall are many pictures. / Such is the result. / Such are the facts.

(二)逻辑意义一致原则:逻辑意义一致就是谓语动词的数必须和主语的意义一致(因有时主语形式为单数,但意义为复数;有时形式为复数,但意义为单数)。

1、what, who, which, any, more, all等代词可以是单数,也可是复数,主要靠意思来决定。如:Which is your bag? / Which are your bags? / All is going well. / All have gone to Beijing.

2、表示"时间、重量、长度、价值"等的名词的复数作主语时,谓语动词通常用单数形式, 这是由于作主语的名词在概念上是一个整体,如:Thirty minutes is enough for the work.

3、若英语是书名、片名、格言、剧名、报名、国名等的复数形式,其谓语动词通常用单数形式。如: "The Arabian Nights"is an interesting story-book.

4、表数量的短语"one and a half"后接复数名词作主语时,其谓语动词可用单数形式(也可用复数。如:One and a half apples is (are) left on the table.

5、算式中表示数目(字)的主语通常作单数看待,其谓语动词采用单数形式。如:Twelve plus eight is twenty. / Fifty-six divided by eight is seven.

6、一些学科名词是以 -ics 结尾,如:mathematics, politics, physics 以及news, works等,都属于形式上是复数的名词,实际意义为单数名词,它们作主语时,其谓语动词要用单数形式。如:The paper works was built in 1990. / I think physics isn't easy to study.

7、trousers, glasses, clothes, shoes, 等词作主语时,谓语用复数,但如果这些名词前有a (the) pair of等量词修饰时,谓语动词用单数。如:My glasses are broken. / The pair of shoes under the bed is his.

8、"定冠词the + 形容词或分词",表示某一类人时,动词用复数。

(三)就近一致原则:在英语句子中,有时谓语动词的人称和数与最近的主语保持一致。

1、当两个主语由either ? or, neither ? nor, whether ? or ?, not only ? but also连接时,谓语动词和邻近的主语一致。如:Either the teacher or the students are our friends. / Neither they nor he is wholly right. / Is neither he nor they wholly right?

2、there be句型be动词单复数取决于其后的主语。如果其后是由and连接的两个主语,则应与靠近的那个主语保持一致。如:There are two chairs and a desk in the room..

注意:Here引导的句子用法同上。

怎样区分英语中的主语，谓语，宾语等

1状语是谓语里的另一个附加成分,它附加在谓语中心语的前面,从情况,时间,处所,方式,条件,对象,肯定,否定,范围和程度等方面对谓语中心进行修饰或限制.

状语与定语相同的地方是,都是前加附加成分;不同的地方是,它是谓语里的附加成分,而定语是主语或宾语里的附加成分.从句子的层次上看,状语是在第二个层次和第三个层次里的成分,有时甚至是更低层次的成分.

2状语的构成

状语的构成经常充当状语的有形容词,副词,时间处所名词,能愿动词,指示代词,以及方位短语,介词短语,动宾短语,谓词性联合短语,谓词性偏正短语,谓词性主谓短语等.

含有动量词的数量短语以及重叠式的数量短语(不论动量,物量)也可以充当状语.

此外,少数名词带上表比况的助词也可以作状语.

3状语的书面标志——"地"

状语的书面标志是结构助词"地".状语后面带或者是不带"地",情况比较复杂.一般讲来,数量短语,主谓短语,动宾短语等作状语时,大都带"地";而介词短语,方位短语,能愿动词,时间处所名词作状语时不能带"地",副词,单音节形容词作状语一般也不带"地".

4多层状语

如果一个中心语前面有好几个状语(多层状语),那就应当注意它们的语序.多层状语的状语个数一般比多层定语的定语个数要少些,其语序也比多层定语的语序要灵活一些.

多层状语的一般语序:

a.表时间的名词或方位短语,介词短语;

b.副词.

c.表处所的介词短语或名词,方位短语;

d.表情态的形容词或谓词短语;

e.表对象的介词短语.

其中副词的位置较为灵活,也可放置在第三项之后.

5一般状语和句首状语

状语在句子中有两种位置:一种是在主语之后,谓语中心之前,如上文所举各例,这是状语的一般位置;另一种是放在主语的前面的,这是状语的特殊位置,这种状语可称"句首状语".

6状语的分类

状语按其修饰的功能不同可分为八大类：

时间状语，条件状语，原因状语，目的状语，结果状语，让步状语和比较状语

答：

①

主语：

用于说明人或事物执行某一动作，

表明“谁”或“什么”。

常由名

词、代词和数词来担任。如：

I

love

the

book

．

The

book

is

my

friend

．我喜欢这本书。这本书是我的朋友。

（名

词作主语）

②

谓语：

说明主语的动作或状态，

表明“做什么”或“是什么”。

常由实义动词

或系动词加上表语部分来充当。如：

Mother

is

a

teacher

．妈妈是一名教师。

（系表作谓语）

She

likes

music

．她喜欢音乐。

（动词作谓语）

③

宾语是动作、行为的对象，由名词、代词、不定式或相当于名词的词、短语来

担任，它和及物动词一起说明主语做什么，在谓语之后。如：

He

learns

English

well

．他英语学得好。

（作动词宾语）

I'm

interested

in

handwriting

．我对书法很感兴趣。

（作介词宾语）

高考独立主格的语法

一、复数性

“the+形容词”表示一类具有某种特征或特性的人时，通常表示复数意义，若用作主语，谓语要用复数。如。如：

The rich get richer and the poor get poorer. 富者愈富，贫者愈贫。

The injured were carried away on stretchers. 用担架把受伤的人抬走了。

The old are more likely to catch cold than the young. 老年人比年轻人更容易感冒。

二、单数性

“the+形容词”若表示抽象概念，则表示单数意义，用作主语时，谓语要用单数。如。如：

He doesn’t know the right from the wrong. 他不辨是非。

The unknown is always something to be feared. 未知的东西总是一种令人害怕的东西。

The beautiful is not always the good, and the good is not always the true. 美未必是善，善未必是真。

三、单复性

有个别的“the+形容词”结构既表示单数意义，也表示复数意义，若用作主语，谓语动词用单数还是复数需视情况而定。如。如：the good 指“好人”时表复数意义，指“善”时表单数意义；the accused 指一名被告时表单数意义，指多名被告时表复数意义。比较。如：

The accused was acquitted of the charge. 被告被宣告无罪。(指一人)

The accused were acquitted of the charge. 被告均被宣告无罪。(指多人)

四、习惯性

有的表达带有一定的习惯性，如“病人”习惯说成 the sick，而不说 the ill；这类结构习惯上不用于-’s 所有格形式，若语义需要，可考虑用 of 所有格。如。如：

正。如：He is interested in the problems of the poor. 他对穷人的问题感兴趣。

误。如：He is interested in the poor’s problems.

主语从句讲解

一、什么是独立主格结构

所谓独立主格结构就是一个与句子相对独立的带有逻辑主语的结构。

由于这个逻辑主语与它所支配的行为状态表达的是辅助主要句子的另一层独立的意思，加之要用代词和名词的主格形式（现代英语中名词的主格与宾格是一致的）表示，因此这种逻辑主语就称作独立主格。逻辑主语加上它所支配的行为状态就构成了一种语法结构，这种语法结构称为独立主格结构。如下列例句中的括号部分：

* (Everyone being ready), the teacher began his class. 每个人都准备好后，老师开始上课。

独立主格（即逻辑主语）：Everyone

独立主格的行为状态：being ready

起到的辅助作用：表示 the teacher began his class 发生的时间

* (It being National Day today)，the streets are very crowded. 由于今天是国庆节,街上很拥挤。

独立主格：It

独立主格的行为状态：being National Day today

起到的辅助作用：表示 the streets are very crowded 的原因

The manager looks relaxed, (many things settled). 由于许多事情已经处理好了，经理看上去很轻松。

独立主格：many things

独立主格的行为状态：settled

起到的辅助作用：表示 The manager looks relaxed 的原因

二、独立主格结构的构成

独立主格由两部分组成——

1、逻辑主语（即独立主格）：由代词的主格或名词充当独立主格

2、叙述语：用来陈述逻辑主语的行为状态。

其中叙述语是独立主格的重点。

三、能够构成独立主格结构中叙述语的词语

1、现在分词（-ing 非谓语动词）

——用作时间状语

The chairman began the meeting , everyone being seated. 每个人坐好后，主席开始开会。（相当于一个时间状语从句after everyone was seated）

——用作原因状语

Many eyes watching him, he felt a bit nervous. 许多眼睛看着他，他感到有点儿紧张。（相当于一个原因状语从句As many eyes were watching him）

——用作条件状语

Time permitting, we will have a picnic next week. 时间允许的话，我们下星期将进行一次野炊。（相当于一个条件状语从句If time permits)

My health allowing, I will work far into the night. 我的健康许可的话，我愿工作到深夜。（相当于一个条件状语从句If my health allows）

——用作伴随方式的状语

The boy lay on the grass, his eyes looking at the sky. 男孩躺在草地上，眼睛看着天空。（相当于一个并列分句and his eyes were looking at the sky）

2、过去分词（-ed非谓语动词）

* The book written in simple English, English beginners were able to read it. 该书是用简单英语写的，英语初学者也能看懂（原因状语 ， = As the book was written in simple English，English beginners were able to read i）

* He was listening attentively in class, his eyes fixed on the blackboard. 他上课专心听讲，眼睛紧盯着黑板。（方式状语，= He was listening attentively in class, and his eyes were fixed on the blackboard. ）

* The task completed, he had two months' leave. 任务完成以后，他休了两个月的假（时间状语。=When the task had been completed,he had two months' leave. ）

3、不定式（to do）

* I send you 100 dollars today, the rest to follow in a year. 现寄给你100美元，其余部分将在一年以后再寄。（方式状语，= I send you 100 dollars today, and the rest is to follow in a year.）

* The manager looks worried，many things to be settled. 经理看上去很着急, 有这么多的事情要处理。（原因状语，= The manager looks worried because many things will be settled）

.

4、形容词短语

* He turned to me, his eyes sleepy. 他睡眼惺忪地转向我。（= He turned to me, and his eyes were sleepy.）

* He stood there, his mouth wide open. 他站在那里，嘴张得大大的。（= He stood there, and his mouth was wide open.）

5、小品副词 .

* School over, we all went home. 放学了，我们都回家了。（= School was over, and we all went home.）

* He sat at his desk, his shoes off. 他坐在课桌旁，没穿鞋子。（ = He sat at his desk and his shoes were off.）

6、介词短语

* He is standing in front of the blackboard, his back towards us. 他站在黑板面前，背对着我们。（ = He was standing in front of the blackboard, and his back was towards us.）

* The new teacher came in, a smile on her face. 新老师面带微笑走了进来。（ = The new teacher came in and she had a smile on her face.）

* The teacher came into the classroom，a rule in his hand. 老师走进教室，手里拿着一把直尺。（ = The teacher came in and a ruler was in his hand.）

怎么区分英语中的主语，宾语，谓语，状语，定语等成分

主语从句，即在复合句中充当主语成分的句子。具体讲解如下：

引导主语从句的连词主要有：

1、常规主语从句，即句子在复合句中充当一个主语。主语从句的时态不受主句时态的影响和限制。

例句

（1）Who will be our monitor hasn't been decided yet.

现在还没有决定谁会成为我们的班长。

（2）Whatever you did is right.

你做的任何事都是正确的。

（3）What we need is time.

我们需要的是时间。

2、名词性从句的时态规则：

主句谓语动词是现在或将来时，从句谓语动词可以用任何需要的时态。

I wonder what he is doing now.我想知道他现在在干什么。

Do you know when and where he was born?你知道他在何时何地出身吗？

主句谓语动词是过去时，从句谓语动词一般需用过去时。

（1）从句与主句的谓语动作同时发生，从句用一般过去时或过去进行时。

I thought that he studied hard.我认为他学习很努力。

He told me his son was watching TV.他告诉我他的儿子在看电视。

（2）从句谓语动作在主句谓语动作之后，从句用过去将来时。

He said he would spend his holidays in Qingdao.他告诉我他将在青岛度假。

（3）从句谓语动作在主句谓语动作之前，从句用过去完成时。

They told me they had waited for me half an hour.他们告诉我他们已经等了我半小时了。

（4）从句如果有表示过去某一具体时间的状语，仍用过去时。

She told me her brother died in 1945.她告诉我她的哥哥（弟弟）死于1945年。

从句时态不受下列客观的条件影响。

（1）从句说明的是不受时间限制的事实或真理（客观真理）。

The teacher told us that the earth turns from west to east.老师告诉我们地球自西向东转。

He said Asia is the largest continent.他说亚洲是最大的大陆。

（2）当从句表示的是反复出现的时态不变。

She told me that she gets up at six o'clock every morning.她告诉我她每天早晨6点起床。

He asked me when the train usually starts.他向我询问火车通常何时出发。

（3）当从句的谓语动作仍在继续时，或者表示现在仍在的状态时，时态不变。

She told me the other day that she is only 10.她告诉我那天她只有10岁。

（4）当从句的动作状态还未发生，要用一般式表示。强调与现在的联系。

He said he will wait for me this evening.他说他今晚将等待我。

3、为了防止句子头重脚轻，通常把形式主语it放在句首位置，真正主语搁置于句末

It is certain that he will win the match.他一定会赢得这场比赛的。

It is very likely that they will hold a meeting.他们很有可能会举行一场会议。
