『叄』 英語中非謂語是什麼意思有什麼形式

非謂語動詞主要包括不定式、動名詞和現在分詞。為了區分這三種不同的非謂語動詞的用法和含義，我們將分別從三種非謂語動詞在句子中做主語、賓語、賓語補足語、定語、狀語、表語以及一些特殊結構句型等角度來區分其用法和細微含義。

1．不定式和動名詞作主語的區別

（1）動名詞作主語通常表示抽象動作；而不定式作主語表示具體動作。 Smoking is prohibited(禁止)here．這里禁止抽煙。(抽象)

It is not very good for you to smoke so much．你抽這么多煙對你身體很不好。(具體)

（2）動名詞作主語時，通常用以表示一件已知的事或經驗。 不定式短語通常用來表示一件未完成的事或目的。

Climbing mountains is interesting．爬山很有趣。(經驗)

Driving a car ring the rush hour is tiring．在高峰時刻開車令人厭煩。(經驗)

（3）不定式做主語，一般用it當形式主語，把作主語的不定式短語後置。 It took me only five minutes to finish the job.

2．不定式、動名詞和分詞作表語的區別

（1）不定式作表語

1)不定式作表語一般表示具體動作，特別是表示將來的動作。

To do two things at a time is to do neither．--次做兩件事等於未做。 What I would suggest is to start work at once.我的建議是立刻開始干。

（2）如果主語是不定式（表示條件），表語也是不定式（表示結果）。 To see is to believe.百聞不如一見。

To work means to earn a living．工作就是為了生活。

（3）如果主語是以aim， ty， hope， idea， happiness， job， plan， problem， purpose， thing， wish等為中心的名詞，或以what引導的名詞性從句，不定式作表語是對主語起補充說明 作用。

His wish is to buy a luxurious car in the near future．他的希望是在不遠的將來買一輛豪華轎車。

The function of Louis Sullivan's architecture was to provide large uninterrupted floor areas and to allow ample light into the interior.

The most important thing is to negotiate with them about the future of the plant．

（2）動名詞作表語：動名詞作表語，表示抽象的一般性的行為。 Our work is serving the people．我們的工作是為人民服務。 His hobby is collecting stamps．他的愛好是集郵。註：動名詞作表語時與進行時態中的現在分詞形式相同，但其所屬結構迥異，進行時態說明動作是由主語完成的。動名詞做表語，說明主語的性質或情況。

People cannot but feel puzzled， for they simply cannot understand how he could have made such a stupid mistake.

His victory in the final was no more convincing than I had expected．

（3）分詞作表語

分詞做表語有兩種情況，一種是現在分詞做表語，一種是過去分詞做表語，這兩者區別是考試中經常考到的地方。一般來說，表示心理狀態的動詞如excite， interest等都是及物動詞，漢語意思不是「激動」，「高興」，而是「使激動」、「使高興」，因而現在分詞應該是「令人激動的」、「令人高興的」，過去分詞則是「感到激動的」和「感到高興的」。所以，凡表示「令人……的」都是-ing形式，凡是表示「感到……」都用-ed形式。換句話說，若人對……感興趣，就是somebody is interested in...,若人/物本身有興趣時，就是說sb./sth. is interesting.

『肆』 英語非謂語

第一個空 enjoy是謂語所以後面要用非謂語，固定搭配加ing
第二個空，what his sister enjoys 是主語，翻譯成他的妹妹享受的是，缺謂語 ，is做謂語，to dance表目的

『伍』 英語中非謂語動詞

都可以
跟這個結構無關
如果及物動詞就可以接名詞
否則就單獨一個do動詞就可以

『陸』 英語，非謂語。

第一題是從說話人的角度考慮，所以用ing表主動，你可以這樣理解
his age,I think he did very well.consider這個動作是主語I發出來的
第六題中what用來引導動詞do的賓語從句，同時在從句中充當賓語成分，that不能這么用的

『柒』 英語中非謂語該如何使用

在英語中，不作句子謂語，而具有除謂語外其他語法功能的動詞，叫做非謂語動詞。非謂語動詞有動詞不定式（the Infinitive）；動名詞（the Gerund）；現在分詞（the Present Participle）；過去分詞（the Past Participle）。

1．非謂語動詞與謂語動詞的相同點有：

（1）如果是及物動詞都可與賓語連用，例如：

They built a garden.

They suggested building a garden.

（2）都可以被狀語修飾：

The suit fits him very well.

The suit used to fit him very well.

（3）都有主動與被動, 「體」式（一般式；進行式；完成式）的變化。例如：

He was punished by his parents.（謂語動詞被動語態）

He avoided being punished by his parents.（動名詞的被動式）

We have written the composition.（謂語動詞的完成時）

Having written the composition, we handed it in.（現在分詞的完成式）

（4）都可以有邏輯主語

They started the work at once.（謂語動詞的邏輯主語）

The boss ordered them to start the work.（動詞不定式的邏輯主語）

We are League members.（謂語動詞的主語）

We being League member, the work was well done.

（現在分詞的邏輯主語）

2、非謂語動詞與謂語動詞的不同點有：

（1）非謂語動詞可以有名詞作用（如動詞不定式和動名詞），在句中做主語、賓語、表語。

（2）非謂語動詞可以有形容詞作用（如動詞不定式和分詞），在句中做定語、表語或賓語補足語。

（3）非謂語動詞可以有副詞作用（如動詞不定式和分詞），在句中作狀語。

（二）非謂語動詞的句法功能：

二、非謂語動詞用法：

（一）動詞不定式：（to）+do，具有名詞、形容詞、副詞的特徵。

1．不定式的形式：（以動詞write為例）

否定式：not + (to) do

（1）一般式：不定式的一般式所表示的動作與謂語動詞動作同時發生或發生在謂語動詞動作之後，
例如：

I'm glad to meet you.

He seems to know a lot.

We plan to pay a visit.

He wants to be an artist.

The patient asked to be operated on at once.

The teacher ordered the work to be done.

（2）進行式：不定式的進行式所表示的動作與謂語動詞動作同時發生，例如：

The boy pretended to be working hard.

He seems to be reading in his room.

（3）完成式：不定式的完成式表示的動作發生在謂語動詞動作之前，例如：

I regretted to have told a lie.

I happened to have seen the film.

He is pleased to have met his friend.

2．不定式的句法功能：

（1）作主語：

To finish the work in ten minutes is very hard.

To lose your heart means failure.

動詞不定式短語作主語時，常用it作形式主語，例如上面兩句可用如下形式：

It is very hard to finish the work in ten minutes.

It means failure to lose your heart.

（2）作表語：

Her job is to clean the hall.

He appears to have caught a cold.

（3）作賓語：

常與不定式做賓語連用的動詞有：want, hope, wish, offer, fail, plan, learn, pretend, refuse, manage, help, agree, promise, prefer, 如果不定式（賓語）後面有賓語補足語，則用it作形式賓語，真正的賓語（不定式）後置，放在賓語補足語後面，例如：

Marx found it important to study the situation in Russia.

動詞不定式也可充當介詞賓語，如：

I have no choice but to stay here.

He did nothing last Sunday but repair his bike.

動詞不定式前有時可與疑問詞連用，如：

He gave us some advice on how to learn English.

（4）作賓語補足語：

在復合賓語中，動詞不定式可充當賓語補足語，如下動詞常跟這種復合賓語：want, wish, ask, tell, order, beg, permit, help, advise, persuade, allow, prepare, cause, force, call on, wait for, invite.

此外，介詞有時也與這種復合賓語連用，如：

With a lot of work to do, he didn't go to the cinema．

有些動詞如make, let, see, watch, hear, feel, have等與不帶有to的不定式連用，但改為被動語態時，不定式要加to, 如：

I saw him cross the road.

He was seen to cross the road.

（5）作定語：

動詞不定式作定語，放在所修飾的名詞或代詞後。與所修飾名詞有如下關系：

①動賓關系：

I have a meeting to attend.

注意：不定式為不及物動詞時，所修飾的名詞如果是地點、工具等，應有必要的介詞，如：

He found a good house to live in.

The child has nothing to worry about.

What did you open it with?

如果不定式修飾time, place, way，可以省略介詞：

He has no place to live.

This is the best way to work out this problem.

如果不定式所修飾名詞是不定式動作承受者，不定式可用主動式也可用被動式：

Have you got anything to send?

Have you got anything to be sent?

②說明所修飾名詞的內容：

We have made a plan to finish the work.

③被修飾名詞是不定式邏輯主語：

He is the first to get here.

（6）作狀語：

①表目的：

He worked day and night to get the money.

She sold her hair to buy the watch chain.

注意不定式放句首時，邏輯主語與句子主語要一致：

wrong：To save money, every means has been tried.

right：To save money, he has tried every means.

wrong：To learn English well, a dictionary is needed.

right：To learn English well, he needs a dictionary.

②表結果：

He arrived late to find the train gone.

常用only放在不定式前表示強調：

I visited him only to find him out.

③表原因：

They were very sad to hear the news.

④表程度：

It's too dark for us to see anything.

The question is simple for him to answer.

（7）作獨立成分：

To tell you the truth, I don't like the way he talked.

（8）不定式的省略：保留to省略do動詞。

If you don't want to do it, you don't need to.

（9）不定式的並列：第二個不定式可省略to。

He wished to study medicine and become a doctor.

（二）動名詞：

動名詞既具有動詞的一些特徵，又具有名詞的句法功能。

1．動名詞的形式：

否定式：not + 動名詞

（1）一般式：

Seeing is believing. 眼見為實。

（2）被動式：

He came to the party without being invited．他未被邀請就來到了晚會。

他不懂英語給他帶來許多麻煩。

2．動名詞的句法功能：

（1）作主語：

Reading aloud is very helpful. 朗讀是很有好處的。

Collecting stamps is interesting. 集郵很有趣。

當動名詞短語作主語時常用it作形式主語。

It's no use quarrelling.爭吵是沒用的。

在螞蟻王國，蟻後的工作是產卵。

（3）作賓語：

We have to prevent the air from being polluted.

我們必須阻止空氣被污染。

注意動名詞既可作動詞賓語也可作介詞賓語，如上面兩個例句。此外，動名詞作賓語時，若跟有賓語補足語，則常用形式賓語it，例如：

We found it no good making fun of others. 我們發現取笑他人不好。

要記住如下動詞及短語只跟動名詞作賓語：

enjoy, finish, suggest, avoid（避免）, excuse ,delay, imagine, keep, miss, consider, admit（承認），deny（否認）, mind, permit, forbid, practise, risk（冒險）, appreciate（感激）, be busy, be worth, feel like, can't stand, can't help（情不自禁地）, think of, dream of, be fond of, prevent…(from),keep …from, stop…（from）,protect…from, set about, be engaged in, spend…(in), succeed in, be used to, look forward to, object to, pay attention to, insist on, feel like

現在分詞既具有動詞的一些特徵，又具有形容詞和副詞的句法功能。

1、現在分詞的形式：

否定式：not + 現在分詞

（1）現在分詞的主動語態：現在分詞主動語態的一般式表示與謂語動詞所表示的動作同時發生，完成
式表示的動作在謂語動詞所表示的動作之前發生，常作狀語。例如：

They went to the park, singing and talking. 他們邊唱邊說向公園走去。

Having done his homework, he played basket-ball. 做完作業，他開始打籃球。

（2）現在分詞的被動語態：一般式表示與謂語動詞同時發生的被動的動作，完成式表示發生在謂語動
詞之前的被動的動作。

The problem being discussed is very important. 正在被討論的問題很重要。

Having been told many times, the naughty boy made the same mistake.

被告訴了好幾遍，這個淘氣的孩子又犯了同一個錯誤。

2．現在分詞的句法功能：

放在名詞後。

In the following years he worked even harder.

在後來的幾年中，他學習更努力了。

The man speaking to the teacher is our monitor's father.

正與老師談話的那個人是我們班長的父親。

現在分詞作定語相當於一個定語從句的句法功能，如：in the following years也可用in the years that followed; the man speaking to the teacher可改為the man who is speaking to the teacher.

（2）現在分詞作表語：

The film being shown in the cinema is exciting. 正在這家上演的電影很棒。

The present situation is inspiring. 當前的形勢鼓舞人心。

be + doing既可能表示現在進行時，也可能是現在分詞做表語，它們的區別在於be + doing表示進行的動作是進行時，而表示特徵時是系動詞be與現在分詞構成系表結構。

（3）作賓語補足語：

如下動詞後可跟現在分詞作賓語補足語：

see, watch, hear, feel, find, get, keep, notice, observe, listen to, look at, leave, catch等。例如：

Can you hear her singing the song in the next room? 你能聽見她在隔壁唱歌嗎？

He kept the car waiting at the gate. 他讓小汽車在門口等著。

（4）現在分詞作狀語：

①作時間狀語：

(While) Working in the factory, he was an advanced worker.

在工廠工作時，他是一名先進工人。

Being a League member, he is always helping others. 由於是共青團員，他經常幫助他人。

He stayed at home, cleaning and washing. 他呆在家裡，又擦又洗。

⑦作讓步狀語：

Though raining heavily, it cleared up very soon.

雖然雨下得很大，但不久天就晴了。

⑧與邏輯主語構成獨立主格：

I waiting for the bus, a bird fell on my heard．

我等汽車時，一隻鳥落到我頭上。

All the tickets having been sold out, they went away disappointedly.

所有的票已經賣光了，他們失望地離開了。

Time permitting, we'll do another two exercises.

如果時間允許，我們將做另兩個練習。

有時也可用with (without) +名詞（代詞賓格）+分詞形式

With the lights burning, he fell asleep. 他點著燈睡著了。

⑨作獨立成分：

udging from(by) his appearance, he must be an actor.

從外表看，他一定是個演員。

Generally speaking, girls are more careful. 一般說來，女孩子更細心。

（四）過去分詞：

過去分詞只有一種形式：規則動詞由動詞原形加詞尾-ed構成。不規則動詞的過去分詞沒有統一的規則要求，要一一記住。

過去分詞的句法功能：

1．過去分詞作定語：

Our class went on an organized trip last Monday. 上周一我們班開展了一次有組織的旅行。

Those elected as committee members will attend the meeting. 當選為委員的人將出席這次會。

注意當過去分詞是單詞時，一般用於名詞前，如果是過去分詞短語，就放在名詞的後面。過去分詞做定語相當於一個被動語態的定語從句。

2．過去分詞作表語：

The window is broken. 窗戶破了。

They were frightened at the sad sight. 他們對眼前悲慘的景象感到很害怕。

注意：be + 過去分詞，如果表示狀態是系表結構，如果表示被動的動作是被動語態。區別：

The window is broken.（系表）

The window was broken by the boy.（被動）

有些過去分詞是不及物動詞構成的，不表示被動，只表示完成。如：

boiled water（開水） fallen leaves（落葉）

newly arrived goods（新到的貨） the risen sun（升起的太陽）

the changed world（變了的世界）

這類過去分詞有：gone, come, fallen, risen, changed, arrived, returned, passed等。

3．過去分詞作賓語補足語：

I heard the song sung several times last week.

上周我聽見這首歌被唱了好幾次。

有時過去分詞做with短語中的賓語補足語：

With the work done, they went out to play. 工作做完了，他們出去玩去了。

4．過去分詞作狀語：

Praised by the neighbours, he became the pride of his parents.

受到鄰居們的表揚，他成為父母的驕傲。（表示原因）

Once seen, it can never be forgotten.

一旦它被看見，人們就忘不了。（表示時間）

Given more time, I'll be able to do it better.

如果給予更多的時間，我能做得更好。（表示條件）

Though told of the danger, he still risked his life to save the boy.

雖然被告之有危險，他仍然冒生命危險去救那個孩子。（表示讓步）
