人教版 高三非謂語動詞複習要點

一、 不定式的用法小結：

1、 在句中所擔當的句子成分：主語、表語、賓語（動詞後的賓語和介詞後的賓語）、定語、補語（尤其是不帶to的動詞原形）、狀語

2、 不定式在句中擔當各成分時的難點及重點

⑴在句中作主語：

①在It is adj. for sb. to do sth. 和 It is adj. of sb. to do sth. 句型中。

在前一句型中形容詞是表示事物特徵的客觀性形容詞。如：difficult, hard, easy, necessary, rare, possible, important, dangerous 等。在後一句型中，形容詞是表示人的品質特徵的主觀性形容詞。如：kind, careful, nice, polite, honest, clever, foolish, wise, lazy等。常可以把這類句型進行改變，因爲邏輯主語既是不定式的主語，又與句子的形容詞存在着主表關係。

e.g. It is kind of you to come to see me = you are kind to come to see me.

②有三個形容詞good, wrong, right 的邏輯主語既可以用of 又可以用for, 但表達的意義不同。

e.g. It is good for you to talk a walk after super. (good 爲“對……有好處，益處”)

It is good of you to be always ready to help others. ( good 爲“善心，好意)

⑵在句中作賓語：

① 只接不定式的動詞：agree, fail, arrange, decide, hope, expect, refuse, manage, promise, pretend, wish, afford, attempt, plan 等。

② 不定式可用在介詞but, except, besides, than之後做賓語。在but, except, besides 前有行爲動詞do時，跟不帶to的動詞不定式；無行爲動詞do時，帶to的不定式，但在than之後的不定式常無to。

e.g. I have no choice but/except to accept the fact.

Little Tom had nothing to do except wander about in the street.

What do you like to do besides swim.

They thought that there was no way out than climb the cliff.

他們認爲除爬懸崖之外無路可出。

③ 不定式在下列動詞後常作真正賓語：

make/find/feel/consider/think/believe +it +adj./n.+ to do sth.

⑶在句中作定語：

① 名詞受the last, the very, the only, 序數詞或形容詞的最進階修飾時， 一定用不定式做後置定語。 e.g. He is always the first person to come.

② 在名詞之後做定語表動作時，用不定式。這些名詞有：effort, failure, promise, desire, attempt 。

e.g. Please make an effort to arrive early.

They had little desire to get rich.

His failure to enter the college made him quite disappointed.

③ 不定式作定語用主動表被動的情況：

Ⅰ.不定式的邏輯主語是主句的主語和賓語，名詞與不定式之間又存在動賓關係，常用不定式的主動表被動。

e.g. I have a lot of work to do./ I’ll give you something to read.

Ⅱ.在某些形容詞之後的狀語，又與主語是動賓關係，用不定式的主動表被動。這些形容詞有：heavy, light, hard/difficult, easy, fit, convenient, comfortable, good, dangerous, safe.

e.g. The question is easy to answer.

The room is comfortable to live in.

Ⅲ. 在there be 句型中，不定式的主動和被動都可以，意義基本一致。

There is a lot of work to do/ to be done.

但：There is nothing to do. (譯爲：沒事可做)

There is nothing to be done. (譯爲：沒有辦法)

⑷不定式在句中作賓補的情況：

① 跟不定式作賓補的動詞：get, ask, tell, allow, permit, want, force, invite, persuade, advise, order, cause, encourage, forbid, wish, drive等。

② 不帶to 的動詞不定式作賓補的動詞：五看兩聽一感覺，外加三個使役詞。如：see, watch, observe, notice, look at, hear, listen to, feel, let, make, have。而help是可有可無to 的動詞。

二、 動名詞：

1、 在句中的作用：主語、表語、賓語、定語

2、 動名詞在句中擔當各成分時的難點及重點：

⑴用動名詞作主語的句型：

It’s no good/ no use doing sth..

There is no doing…. (……是不行的，做……是不可能的)

It’s worthwhile doing sth. (做……是值得的)

e.g. There is no joking about their belief. 拿他們的信仰來開玩笑是不行的。

It’s worthwhile taking the trouble to explain a job fully to new employees.

給新僱員詳細解釋一下工作要求，費點事也是值得的。

⑵動名詞在句中作賓語：

① 作介詞的賓語

② 只接動名詞作賓語的動詞：enjoy, finish, mind, miss, suggest, advise, appreciate, avoid, imagine, admit, consider, delay, practise, forbid, deny, allow, permit, require, risk, excuse, prevent, complete, resist(抵抗)

③ 只接動名詞的短語動詞：give up, feel like, be worth, be/become/get used to, lead to, look forward to, object to, stick to, be fond of, pay attention to, be engaged in, put off, keep on, prevent/ keep/ stop…from, set about, can’t stand, get through(完成)等。

④ 在可省略的介詞in 之後做賓語：

have difficulty/ trouble/ problem/ fun/ pleasure (in) doing sth.

have a good time/ a hard time (in) doing sth.

spend/waste time/ money (in) doing sth.

be busy (in) doing sth.

There is no use/ no harm/ no hurry/ no point (in) doing sth.

There is no harm in staying up a little later.

⑶動名詞的複合結構在句中的使用：

有時爲了說明動名詞的動作是由誰來執行的，通常用名詞的所有格或形容詞性的物主代詞來做動名詞的邏輯主語。在口語中，動名詞複合結構的邏輯主語也可以用賓格或普通格來做。 如：

Their coming to help us was a great encouragement.

The mother’s worry is her son’s going to bed too late.

Do you mind me opening the door?

但在以下幾種情況通常用普通格來做邏輯主語：

① 邏輯主語是無生命的名詞時，如：Is there any hope of your team winning the game?

② 邏輯主語是不定代詞，指示代詞時，如：

Last night he was waked by someone knocking at the door.

③ 邏輯主語是兩個或兩個以上的單位時：

I still remember you and your father coming to see me many years ago.

三、 分詞：

１、分詞在句中的作用：表語、定語、狀語、補語。

２、分詞在句中作表語

現在分詞在句中作表語，表示主語的性質與特徵，它相當於一個形容詞的作用。過去分詞在句中作表語，表示主語所處的狀態或已完成動作的狀態。

e.g. The film is interesting / moving.

He is well educated.

75% of the surface of the earth is covered with water.

使役動詞所轉變而成的形容詞也常被認爲是分詞作表語。現在分詞形式表某人或某物給別人的感覺；過去分詞形式表說話者的主觀感受。這些使役動詞常有：interest, surprise, frighten, excite, astonish, bore, tire, annoy, encourage, discourage, satisfy, disappoint, inspire, move, please, confuse, amuse, shock, worry, puzzle等。

3、分詞在句中作定語：

⑴ 動詞的現在分詞在句中作前置定語，都表示動作的進行及主動，現在分詞短語作後置定語，相當於一個主動的定語從句。如：

a sleeping boy / the changing world / the rising sun

The teacher talking with the students will give us a report.

Most of the assistants working in this shop are young people.

注意：有時單個的現在分詞也作後置定語，強調動作正在進行。

a cleaning woman ( 一位女清潔工)

a woman cleaning （一位正在打掃的婦女）

a dancing girl 一位舞女(永久性)

a girl dancing 一位正在跳舞的女孩 (暫時性)

⑵不及物動詞的過去分詞作前置定語，表示動作的完成；及物動詞的過去分詞作前置定語，既表動作完成，又表被動。如：

vi. a returned soldier/ retired teachers/ the risen sun/ a sunken ship

vt. the murdered man/ a finished article/ the stolen bike.

但只有及物動詞的過去分詞能在句中作後置定語，相當於一個被動的定語從句。

He is the man loved by all.

Your letter dated March 10 has been received.

注意：現在分詞的完成式和完成被動式不在句中作定語。

4、分詞在句中作賓補：

⑴現在分詞通常在句中做以下動詞的賓補，表主動及動作的正在進行或持續。如：see, watch, observe, notice, look at, hear, listen to, feel, find, want, catch, smell及這些有“使……”的詞，send, leave, set, get, keep, have 等。

e.g. I could smell trouble / danger coming./ His words set me thinking.

He left me lying there alone. / The earthquake sent the glass flying everywhere.

I don’t want people coming in and out all day. ( want一般用於否定句中)

⑵過去分詞通常在句中做以下動詞的賓補，表被動。如：see, watch, observe, hear, listen to, look at, notice, feel, find, make, have, want, leave, get, wish等。

e.g. I want that letter typed by tomorrow.

I must get the work finished before Sunday.

Who left the door unlocked?

注意：現在分詞的完成式和完成被動式及being done結構不在句中作賓補。

5、分詞在句中作狀語：

⑴分詞在句中作狀語時，其邏輯主語必須與主句主語保持一致。如果不一致時，就必須分詞加上自己的邏輯主語，構成分詞的獨立主格結構。如：

The weather being fine, we decided to go for an outing.

`Winter coming, the mountain is covered by snow.

There being no bus, we had to go home on foot.

The telephone number given, we called him at once.

Everything considered, the plan is practical.

⑵現在分詞在句中作狀語，表主動；過去分詞表被動。being done 結構通常不在句中作狀語。

⑶現在分詞的完成式在句中作狀語時，既表主動，又表先於主句謂語動作發生的動作或已完成動作；現在分詞的完成被動式作狀語，既表被動，又表先於主句謂語動作發生的動作。

⑷否定詞not要加於分詞之前。

e.g.. Having a written examination, I am forced to study hard.

The visiting Minister expressed his satisfaction with the talks, adding that he had enjoyed his stay here.

Seen from a spaceship, the earth looks just like a big blue water ball.

Not having seen her for years, we could hardly recognize her.

Having been hit by the big boy on the nose, the little boy began to cry.

⑸分詞的獨立形式，即分詞作狀語，沒有邏輯主語，而是修飾整個句子。如：generally/ frankly/strictly/ honestly speaking, judging from/by, compared to/with.

e.g. Generally speaking, he is fit for the position.

Judging from his accent, he is from the south.

Compared with other companies, our staff turnover(人員流動率) is low.

四、 不定式、動名詞和分詞用法的比較：

1、 不定式與動名詞作主語的區別：

⑴不定式作主語常表示一次性具體行爲，動名詞通常表示習慣性、經常性的動作。

⑵主語用不定式，表語用不定式；主語用動名詞，表語用動名詞。

e.g. To do this work is very difficult./ Teaching English is my job.

To see is to believe. / Seeing is believing.（這兩個句子的主表位置不能交換）

2、 不定式與動名詞作賓語的區別：

⑴ like/ love/ continue/ begin/ start 後接to do 和 doing的區別不大，但在以下幾種情況時多用不定式（to do ）.

① would like / would love + to do sth.

② start/ begin 的主語爲it 或物質名詞時，用不定式。

e.g. It began to rain./ The ice began to melt.

③ start/ begin 本身爲進行時, 用不定式。

e.g.. I’m beginning to talk about it.

④ 當start/ begin後接某些表感覺或心理活動的動詞時，用不定式。如：understand, see, realize, feel, find, know，believe等。

e.g. I began to understand the meaning which begins to be clear.

⑵有一些動詞接to do 與doing 有明顯的區別。

to do 要去做的事

forget/ remember 忘記/記住

doing 已做了的事

to do 遺憾未做的事 to do 設法去做，努力地去做

regret try

doing 後悔做了的事 doing 試着做

to do 打算去做 to do 學會做（已會做）

mean learn

doing工意味着 doing 學習做（不一定會）

to do 繼續做另一件事 to do 不能幫助去做

go on can’t help

doing 繼續做同一件事 doing禁不住，忍不住做

to do sth. 害怕而不敢做

be afraid

of doing sth. 擔心……，害怕做……

to do 停下來做另一事 to do 離開去做另一件事

stop leave off

doing 停止正在做的事 doing 停止正在做的事

to do

need/want/ deserve 需要/ 值得去做

require/ be worth +doing (主動表被動)

3、不定式、動名詞和分詞作表語的區別：

⑴ 不定式與動名詞在句中作表語的異同。

不定式與動名詞作表語都是爲了說明主語的內容。它們作表語時，都能與主語換位，其邏輯意義不變。但不定式側重表示具體的動作或表未發生的動作，動名詞則表習慣性、經常性動作。回答 what的提問。

e.g. Our plan is to train the students’ speaking ability.

His wish is to become a famous teacher.

Its full-time job is laying eggs.

⑵現在分詞作表語表主語的性質、特徵。回答how 的問題；過去分詞表狀態或已完成動作的狀態。

e.g. The problem is puzzling./ The joke is amusing.

The sun is set in the west./ Her necklace was gone.

4、不定式、動名詞和分詞作定語的區別：

⑴動詞不定式常常放在名詞或不定代詞後面作後置定語，其邏輯主語往往是句子的主語，故動詞不定式作定語時往往用主動式；如果動詞不定式的邏輯主語不是句子的主語，該動詞不定式要用被動式。動詞不定式作定語往往表示尚未發生的動作。如果動作已發生或正在發生，一般用現在分詞作後置定語。如果是動作已經完成且又與名詞是被動關係時，就用過去分詞作後置定語。動名詞不作後置定語。例如：

e.g. Do you have anything to do tonight? 你今晚有什麼事要做嗎?

I am going to Shanghai tomorrow. Do you have anything to be taken there? 明天我要去上海。你有什麼東西要捎去的嗎?

I have no pen to write with．我沒有鋼筆寫字。

Please tell me the subjects to be discussed at the next meeting.

Have you read any short stories written by Luxun?

The professor being talked will come here tomorrow.

⑵動名詞與現在分詞作前置定語的區別：

動名詞作定語表示它所修飾名詞的目的、用途、性能或作用，二者無邏輯上的主謂關係，但可以變成for引導的介詞短語；而現在分詞作定語表示它所修飾名詞的動作或狀態，二者是邏輯上的主謂關係。如：

a sleeping boy = a boy who is sleeping

a sleeping car = a car for sleeping

a dancing girl = a girl who is dancing

a dancing hall = a hall for dancing

⑶既能用不定式又能用of +動名詞來修飾的名詞：

of + doing

way/pleasure/chance/power

to do

e.g I have no chance of speaking to him/ to speak to him.

5、過去分詞、現在分詞、和不定式作賓補的區別。

現在分詞作賓補：賓語和補語之間是主謂關係。其動作正在進行或持續也可使動作具有描寫色彩。過去分詞作賓補：賓語和補語之間是被動的關係。不定式作賓補：　表一個已完成的動作的全過程或一次性動作也可表事實。

e.g: I saw him open the window. /I saw him opening the window. / I saw the window opened.

I heard the song sung in English. / I heard her sing the song in English.

We saw the sun rise./ We saw the sun rising behind the trees.

6、不定式與現在分詞作狀語的區別：

⑴作原因狀語的區別：

不定式作原因狀語，常放在某些表示人的感情的動詞或形容詞之後，不能置於句首，也不能換成原因狀語從句。不定式所表示的動作一般發生在謂語動作之前。現在分詞作原因相當於一個原因狀語從句，常置於句首，常用表狀態的動詞，偶爾也表動作的動詞。如：

e.g. We laughed to see the new book.

We are proud to be young people of New China.

She look happy to hear the good news.

Being ill, he was unable to go to school.

Not knowing her address, we couldn′t find her.

Having seen the film before, I didn′t go to see it last week.

⑵作結果狀語的區別：

不定式作結果狀語，表意想不到的結果，現在分詞作結果狀語，表自然而然的結果。

e.g. He lifted a rock only to drop it on his own feet.

He arrived at the station to be told the train had gone.

Tom fell from a tree, breaking his arm.

They open the fire , killing one of our villages.

⑶不定式在句中作狀語，通常表目的、結果或原因；分詞作狀語可表時間、條件、伴隨、讓步、方式、結果、原因等。

五、 動名詞、現在分詞和進行時的區別：

這三種在形式上完全相同，都是be+ving的結構，但在意義上是完全不同的。動名詞作表語都是爲了說明主語的內容，能與主語換位，其邏輯意義不變。現在分詞作表語表主語的性質、特徵。而進行時態，則是強調主語的動作，且不能與主語換位。如：

e.g. His purpose is serving the people.= Serving the people is his purpose.

He is serving the people.

“The Internationale”（國際歌） is inspiring.

“The Internationale” is inspiring the workers of the whole world.

六、 過去分詞與被動語態的區別：

過去分詞作表語表示主語所處的狀態或完成某動作的狀態。而被動語態表示主語所承受的動作。

e.g.. The window was broken by his brother. (被動語態)

The window was broken. （系表關係）

He is well educated. （系表關係）

He has been educated in this college for three years. （被動語態）
