主,谓,宾的结构,一个句子中的主,谓,宾有什么固定搭配

希望对你有用！！

望采纳======

主谓宾结构:本结构是由主语+及物的谓语我们相信他是有罪的。动词+宾语构成。宾语成分的多样化使得这一结构异常复杂。

如：1. Tom made a hole in the wall.

2. I don’t know if he can come tomorrow.

3. They hen’t decided where to go next.

4. She stopped teaching English two years ago.

什么是主语？主语是一句话中所要介绍描述说明的主体对象，可以是人，物，事情。

什么是谓语？谓语是一句话中1.主体对象所发出或承受的动作行为;由行为动词承担。或者2.是对主体对象的介绍﹑描写或判断部分。

主语和谓语动词（种谓语）的关系：主语是谓语的施事或受事。

什么是宾语？宾语是动作的对象，可以是人，物，事情。

谓语和宾语的关系：宾语是谓语的受事。

据语言学家研究，人类的各种语言主谓关系大体是一致的，英语和汉语也不例外。

汉语有时主语、谓语和宾语的关系字面表达非常清楚；有时把主语隐藏起来，需要通过上下文辨识出主语所指；有时没有主语；谓语可以由各种词类承担。

英语的句子结构，主谓宾的逻辑关系文字表达清晰，动作与施事或受事之间的关系明白无误；除了祈使句主语可以省略之外，其他所有句子一定有主语；谓语由动词承担。

一．英汉主语的区别。

主语可以指人、物、事情。指人、物时用名词或代词，这一点英汉两种语言相同，其中的区别是英语的名词有单复数之变形，还涉及冠词的配合，代词也有变化，可以参考词类部分讲解，在此不再重复。

（一）当主语指人、物时，还需要注意以下问题：

1．汉语有时看似有主语，如：

现在正下着毛毛雨。

全市到处在兴建新工厂。

生活中没有失败只有成功。

观察划线词，放在谓语动词的前面，看似主语，但分析与动词的逻辑关系，与动作没有施事或者受事的关系，从主谓的定义来说，就不是主语。从语义来看，这些词其实是修饰动作的，表示的是动作发生的时间或地点意义，这种句式在英语中要么是用受事做主语，要么就是it或there来做主语.

It’s drizzling at the moment.

New factories are being built all over the city.

There are no failures in life, but only results.

2．有些动词汉语用人做主语，英语是事物做施事主语，人作受事宾语。

你出什么事啦？

What has happened to you?

3．汉语可以没有主语，也可以变换主语并予以隐含。

发现了错误，一定要改正。

他有个女儿，在工作，已经打电话去了，听说明天就能回来。

种情况汉语主语不明，在英语中用受事宾语做主语；第二种情况主语通过上下文可以推论出来的，在英语中需要清楚地用文字表示。

Wrongs must be righted when they are discovered.

He has a daughter, who works in Beijing. Someone has phoned her and it is said that she will be back tomorrow.

4．汉语的受事宾语在英语中是施事主语。

出现问题了。

Problems arose.

他们下月举行婚礼。

Their wedding will take place next month.

（二）当主语指一件事情或者活动的时候，英语需要用that/wher/who/what/which/how/ where/when/why 的一个句子来表示或者是用to+动词或动词+ing 来表示。

1．指事情，用句子。

我们所需要的是更多的时间。

这孩子能否上大学还是个问题。

That he was ungrateful cut her to the heart.

What we need is more time.

Wher my child is able to go to college remains a problem.

2．指事情或活动，相当于汉语“(对某人来说)做某某事情是…”的意思, 英语常用It is +adj. + (for ) to+动词原形或（物主代词/某人’s+）动词+ing来表示。

（1）用形容词或名词use, good, pity, fun, worth, worthwhile等来描述说明这件事情/活动时，用动词+ing.

你喝这么多酒对身体不好。

Your drinking so much wine is not good for health.

利安娜来这儿能帮大忙。

Liana’s coming here will be a great .

翻书弄出好响的声音。

Turning pages makes a lot of noise.

（2）用其它形容词或名词的时候则用（conj.+）to+动词原形。

怎样使我们活得更长是个大问题。

How to make our life longer is a big problem.

人们为钱而结婚是错4、beg和begfor意为“请求”时，比ask和ask for语气要重。当用boon，four，lee，pardon，forgiveness和permission等词和施舍物时，多与beg搭配；误的。

做这样的事是违反我的原则的。

It is against my principles to do such a thing.

二．谓语英汉对比。

从谓语的定义，我们可以看到，谓语部分可以分为两种情况：1.主体对象所发出或承受的动作行为，由行为动词承担。 2.是对主体对象的介绍﹑描写或判断部分。

种谓语由动词承担，这一点英汉是一样的，只要有相应的词汇就能表达，此处不多叙述。其中也有不同点，那就是：英语的谓语动词需要根据不同的时间意义变化词形，我们将在后面章节叙述。

第二种谓语英汉则有较大别。

先看下列汉语例句，将谓语划分出来。

房间干干净净。

今天星期五。

他们在楼上。

汉语这类谓语复杂多样，可以由名词、形容词、数词、副词、介词短语来承担。

英语的谓语在这种情况下，则由动词be+名词、形容词、数词、介词短语来承担。be有时相当于汉语的“是”字，多数时候是没有对等的汉语意义的，所以常常被我们所忽略，一定要特别注意。Be 的词形也要随时间意义的不同而变化。

将上述汉语例句译为英文：

The room is neat and tidy.

Today is Friday.

This box weighs eighty pounds.

They are upstairs.

仔细阅读下面的句子，把谓语部分划出来，并译为汉语。

They are birds of a feather.

I called on him; but he wasn’t in.

I don’t think that I’m wrong.

The little girl is 12 years old.

China is determined to catch up with the other aanced countries in the world.

I am at a loss what to do next.

We are all ears in class.

The light was on the whole night.

Visits are down at least 40%.

他们是一丘之貉。

我去拜访他，但他不在家。

她还活着吗？

我认为我没错。

这个小女孩儿12岁。

决心赶上世界发达。

我不知道下一步怎么办。

我们上课都专心听讲。

灯开了一夜。

参观次数少了至少40%。

从上述例子还可以看到，英语的谓语“be+ 副词/介词短语”的形式往往等于汉语某个动词/词组作谓语的意思，这是在英汉两种语言结构转换时也应当多多注意的地方。

三．英汉宾语对比。

宾语是行为动词的动作对象，指人、物时用名词或代词，这一点英汉两种语言相同，其中的区别是英语的名词有单复数之变形，还涉及冠词的配合，代词也有变化，可以参考词类部分讲解，在此不再重复。

我们来重点看看当宾语指事时，英汉ask, beg, choose, expect , hate, intend like, love, need prefer, prepare, promise, want, wish…的区别。

I’m absoluy sure I locked the door. I clearly remember locking it.

I remembered to lock the door when I left but I forgot to shut the windows.

I’ll do the shopping when I’ve finished cleaning the flat.

He tried to oid answering my question.

He yo considered going to live in another country?

It was late, so we decided to take a taxi home.

Simon was in a difficult situation, so I agreed to lend him some money.

I pretended to be reading the news.

Ask Jack. He’ll l you what to do.

I don't want there to be another mistake.

从上述例句我们不难看出，当宾语是一件事或者说是一个活动的时候，英语需要用that/wher/who/what/which/how/ where/when/why 的一个句子或to+动词或动词+ing 来表示。跟句子的情况与汉语词序类似，连接词的用法可参考主语部分内容，此处不多说。跟动词的情况是什么样的呢？这是词语搭配的问题，是由谓语动词及时间意义来决定动宾搭配的。

1．跟to +动词作宾语的常用动词。

agree , ask , attempt , afford, appear , choose , claim, decide, decline, dare , dislike, expect, fail happen , hate , hesitate, hope, intend ,learn , ma , offer, promise, plan, prepare , pretend refuse , seek , want, wish, etc.

有一种现象需注意：feel, find, make, think, consider 等动词后如果是to +动词作宾语带形容词/名词作补足语，常用 it作形式宾语，把to+动词后移，即verb+it+adj/n+to do结构.

I find it difficult to work with him. He thought it a great pity not to he invited her.

She made it a rule to get up at five

2．跟动词+ing 作宾语的常用动词。

Admit, stand, oid, consider, deny, enjoy, escape, finish, keep, mind, tpone, pract, prnt, quit, resist, suggest, aise, acknowledge, ban, prohibit, etc.

3．可以跟to+ 动词,也可以跟动词+ing, 但意义不同的常用动词。

Stop, remember, regret, try, want, mean, go on, etc.

I remember ting the letter. (寄了)

Please remember to t the letter. （要寄）

I now regret saying what I said. I shouldn’t he said it. （后悔）

We regret to rm you that we are unable to offer you the job. （遗憾）

What do you mean to do? （打算）

His words mean refusing us. （意味着）

They want to repair the house. (想要)

The house wants repairing. （需要）

I found him lying on the ground.

I found it important to learn.

I found that to learn English is important.

典型例题:

The next morning she found the man ___ in bed，dead.

A. lying B. lie C. lay D. laying

2）of 的句型一般用表示人物的性格，品德，表示主观感情或态度的形容词，如good, kind, n, clr, foolish, right。

It’s very n of you to me. 你来帮助我，你真是太好了。

for 与of 的辨别方法：

用介词后面的代词作主语，用介词前边的形容词作表语，造个句子。如果道理上通顺用of，不通则用for。如：

You are n. (通顺，所以应用of)。

He is hard. (人是困难的，不通，因此应用for。)

7.5 不定式作表语

7 go on to do go on doing

8 afraid to do afraid doing

10 mean to do mean doing

11 begin/ start to do begin/ start doing

与allow用法相似的词

It is wrong for people to marry for money.

allow的同义词如下：

7.1 不定式作宾语

1."允许;同意"释义下的同义词

admit let permit grant consent

2."承认"释义下的同义词

acknowledge concede recognize

其他释义下的同义词

concede consent recognize tolerate lnse render accede sanction grant let permit admit acknowledge

allow的基础像义

vt. 允许; 承认; 给予; 准许（做某事）;

vi.To 容许; 考虑;

beg的用法 可用作不及物动词

What time is it? It’s ten sharp. 几点啦？十点啦。

1、beg的基本意思是指谦卑地、甚至低三下四地“乞求”“恳求”,可乞求生活必需品如饭、钱等,也可恳求其他非物质的东西,也可表示“祈求”某事物。

2、beg可用作不及物动词,也可用作及物动词。用作及物动词时可接名词、代词、动词不定式(短语)或that从句作宾语,也可接以动词It’s so n to hear your vo.不定式充当补足语的复合宾语。

3、beg后不可用于“beg++sth”句型。表物宾语可用介词for引出; 表人宾语则可用介词of引出。

5、可以存在Shebegged him to...，Shebegged of him to...或Shebegged that..3。宾语补足语。.等表达方式；

6、beg(lee) to state，beg(lee) to acknowledge，beg(lee) to rm等词都是较为礼貌的用法，一般作为商业信函中的客套语，在普通信函中尽量少用；

7、beg指“向某人乞求”，在被请求的人前面用of或from。

一些语法问题？

11 begin/ start to do begin/ start doing

如果完整话为This might not be right,but school-leers who fail to acknowledge as much risk the wrong decision about going to university. 那么，关系如下：

submit to

but是转折词。

decide, know, consider forget, learn, remember, show, understand, see, wonder, hear, find out, explain, lthe school-leers，是主语，也是定语从句的先行词。

risk是句子的谓语。...结尾是动名词短语作宾语。

who...as muc，定语从句。其中who是主语，fail谓语，to acknowledge.是不定式短语作宾语。as much是程度副词。

整个意思是，这样做可能不对，但缺乏足够意识的离校者在上大学问题上冒有做出错误决策的风险。

苹果用法语怎么读？香蕉用法语怎么读？西瓜用法语到底怎么读呢？还有水果用法语怎么读？水用法语怎么读？牛肉用法语怎么读？汤法语怎么读？添加视频的法语怎么读？

3)表原因

I'm glad to see you.

The chair looks rather hard, but in fact it is very comfortable to ___.

It's good to see you again.动词不定式to see you again做真正的主语，形式主语是it。

To speak is to practise.动词不定式分别做主语和表语。

动词不定式的基本形式是“to＋动词原形”，有时可以不带to。动词不定式（或不定式短语）没有人称和数的变化，在句子中不能作谓语。动词不定式仍保留动词的特点，即可以有自己的宾语和状语。动词不定式同它的宾语或状语构成不定式短语。

动词不定式具有名词、形容词和副词的特征，因此在句子中可以作主语、宾语、表语、宾语补足语、定语和状语。

1．作主语

作主语用的动词不定式常常用it替代，动词不定式（或短语）放在后面。例如：

It is terrible to see the ship sinking into the sea．目睹轮船沉入大海，真是太可怕了。

2．作宾语

Indians like to eat hot food．印度人喜欢吃辣味食品。

They need to look at a map．他们需要查看地图。

有的动词不定式在作带有补足语的宾语时，前面往往带有形式宾语it。例如：

Do you think it necessary for us to learn to wait？你认为学会等待对我们来说很必要吗？

They improved the software to make it easier for people to use comrs．他们改进了软件，使人们使用计算机更简便了。

3．作表语

It seems to be an interesting book．它看起来是本有趣的书。

The old man's job is to take care of the flowers in the garden．这位老人的工作是照料花园里的花。

4．作宾语补足语

Who taught you to play the music？谁教你弹这支曲子的？

5．作定语

动词不定式作定语时，要放在它所修饰的名词或代词后面。例如：

In his third year，he left Harvard to work for a company called Microsoft．在三年级时，他为了去微软公司工作而离开了哈佛大学。

（2）表示结果

动词不定式作状语表示结果时常与副词too或enough连用。例如：

The Californian ship arrived too late to se more people．加利福尼亚号来得太晚，没能挽救更多的人。

7．和某些形容词连用

和动词不定式经常连用的形容词有sure，ready，happy，sorry，afraid等。例如：
