動詞不定式
動詞不定式:(to)+ do,具有名詞、形容詞、副詞的特徵。否定式:not+(to) do
以do為例,動詞不定式的構成如下:
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:
It's nice to meet you.很高興見到你。
He seems to know a lot. 他看起來懂得很多。
We plan to pay a visit. 我們計畫去參觀。
He wants to be an artist. 他想成為一個藝術家。
The patient asked to be operated on at once. 病人要求馬上手術。
The teacher ordered the work to be done. 老師要求完成工作。
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. 男孩假裝工作得很努力。
He seems to be reading in his room. 看起來他正在他的房間裡面讀書。
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 having told a lie. 我後悔我說謊了。
I happened to have seen the film. 我偶然看過這部電影。
He is pleased to have met his friend. 他很高興能遇上他的朋友。
不定式的句法功能:(1)作主語:
To finish the work in ten minutes is very hard. 十分鐘之內完成這項工作是很難的。
To lose your heart means failure. 灰心意味著失敗。
動詞不定式短語作主語時,常用it作形式主語,真正的主語不定式置於句後,例如上面兩句可用如下形式:
It is very hard to finish the work in ten minutes. 十分鐘之內完成這項工作是很難的。
It means failure to lose your heart. 灰心意味著失敗。
常用句式有:1、It+be+名詞+to do。2、It takes sb.+some time+to do。3、It+be+形容詞+of sb +to do。常用careless,,clever,good,foolish,honest,kind,lazy,nice,right,silly,stupid,wise,等表示讚揚或批評的形容詞,不定式前的sb.可作其邏輯主語。
2.作表語:
Her job is to clean the hall. 她的工作是打掃大廳。
He appears to have caught a cold. 他似乎感冒了。
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. 馬克思發現研究俄國的情況是很重要的。
動詞不定式也可充當介詞賓語,如:
I have no choice but to stay here. 我只能留在這裡,別無選擇。
He did nothing last Sunday but repair his bike. 他上周日除了修他的腳踏車什麼也沒幹。
動詞不定式前有時可與疑問詞連用,如:

4.作賓語補足語:
在複合賓語中,動詞不定式可充當賓語補足語,如下動詞常跟這種複合賓語:want,wish,ask,tell,order,beg,permit,help,advise,persuade,allow,prepare,cause,force,call on,wait for,invite.
此外,介詞有時也與這種複合賓語連用,如:
With a lot of work to do,he didn't go to the cinema. 他有很多工作要做,所以沒去電影院。
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. 我看見他橫過公路。
He was seen to cross the road. 他被我看見橫過公路。
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係:
①動賓關係:
I have a meeting to attend. 我有一個會議要出席。
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. 他找到了一個居住的好房子。

What did you open it with? 你用什麼打開它?
如果不定式修飾time,place,way,可以省略介詞:

This is the best way to work out this problem. 這是解決這個問題的最好辦法。
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 be sent? 你有什麼東西需要送嗎?
②說明所修飾名詞的內容:
We have made a plan to finish the work. 我們制定了一個完成工作的計畫。

6.作狀語:
①表目的:

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. 為了省錢,他使出了渾身解數。
wrong:To learn English well,a dictionary is needed.
right:To learn English well,he needs a dictionary. 為了學好英語,他需要一本詞典。
②表結果(往往是與預期願望相反的結果 意料之外):常放在never only後

現在分詞
現在分詞:
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。
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。
現在分詞的句法功能:
1.作定語:現在分詞作定語,當分詞單獨做定語時,放在所修飾的名詞前;如果是分詞短語做定語
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:

⑧與邏輯主語構成獨立主格:

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。

⑨作獨立成分:

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。
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。
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 selected 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)

Filled with hopes and fears,he entered the cave. 心中充滿了希望與恐懼,他走進山洞。
不定式
1.“to” 是不定式符號還是介詞,下列短語中的to 都是介詞。
agree to object to close to,come to,lead to,refer to,
equal to,familiar to,point to,thank to,devote to,next to,belong to,be used to,look forward to
2.帶to 還是不帶to
I have no choice but to give in
I cannot do anything but give in
I saw him enter the classroom .
( 但是:He was seen to enter the classroom .)
3.動詞不定式邏輯主語是由for作為標記的。但是有時用of。
區別:當使用for時,句中形容詞修飾的是不定式;而用of時,句中形容詞修飾邏輯主語。
It’s necessary for you to study hard .(necessary 修飾 to study hard,表示學習努力是有必要的)
It’s foolish of him to do it .(foolish 修飾邏輯主語him)
與of連用的形容詞有:
good,kind,nice,wise,clever,foolish,right,wrong,careful,careless,polite,…
與for連用的通常是一些表示可能性、難易程度、必要性等含義的形容詞:
possible,impossible,easy,hard,difficult,necessary,…
4.後接不定式作賓語的動詞有:
want,hope,wish,like,begin,try,need,forget,agree,know,promise,teach,refuse,help,arrange,dare,decide,determine,fail,manage,offer,prepare,continue,ask,mean,choose,expect etc.
需要賓語補足語的動詞不能用動詞不定式直接做介詞的賓語,而要用it做形式賓語。例如:通常不說We think to obey the laws is important . 而說We think it important to obey the laws .
5.不定式作賓語補足語時省略to的情況:若不定式前的謂語動詞是使役動詞make,let,have(表示“讓、使”)、感官動詞see,watch,look at,observe, notice,hear,listen to, feel時,不定式符號to可以省略。這些動詞亦可總結為口訣:“三使五看兩聽一感覺”。例如:
Let's(to)go!走吧!
He saw the thief (to)steal a lady’s cellphone.
註:改為被動句時要把to還原,例如:
The thief was seen tosteal a lady’s cellphone.
6.不定式的省略。下列短語中,如果意義明確,常常省略到to。
want to,wish to,hope to,like to,hate to,plan to,try to,love to,have to,ought to,need to,used to,be able to
7.不定式作定語,應注意兩種關係:
1)動賓關係:
He has a lot of meeting to attend .
Please lend me something to write with .
He is looking for a room to live
He is looking for a room to live in .
He has no money and no place
to live ( in ) .
I think the best way to travel ( by ) is on foot .
There is no time to think ( about ) .
2)主謂關係:
She is always the last ( person) to speak at the meeting .
----I’m going to the post office,for I have a letter to post . ( 邏輯主語是I )
-------Thank you. But I have no letters to be posted now ( 邏輯主語不是I )
7.不定式作狀語,可以有以下幾種意義:
1)原因
He is lucky to get here on time .
這種結構中常用的形容詞有:
happy,glad,delighted,pleased,sorry,eager,anxious . lucky,fortunate,proud,angry surprised,frightened,disappointed,ready,clever,foolish,worthy
2)目的
He came to help me with my maths .
3)結果
I hurried to get there only to find him out .
The book is too hard for the boy to read .
He is old enough to go to school .
8.不定式作補足語
I saw him play in the street just now .
能跟不帶to 的不定式作補足語的動詞有:
see,feel,hear,listen to,look at,watch,let,have make,observe,notice
註: 當這些詞為被動式時,不定式要帶to,如:
He was seen to play in the street just now.
典型習題
1.The Olympic Games, ______ in 776 B.C,did’t include women players until 1919.
A.first playing B.to be first played C.first played D.to be first playing
析:根據題乾,必須選表示被動的選項,故排除A、D;因B選項表“將要被舉行”意,不合題乾之用,只有C選項(相當於which was first played)才合用。
2.European football is played in 80 countries, ______ it the most popular sport in the world.
A.making B.makes C.made D.to make
析:B、C是謂語動詞,在此不可用。D項to make或表目的,或表“將要使得”,這都不合題乾情景。只有A.making,可作狀語,表結果。再舉一現在分詞作結果狀語例:
The bus was held up by the snowstorm,causing the delay.公共汽車被大風雪所阻,因而耽誤了。
3.Little Jim should love ______ to the theater this evening.
A.to be taken B.to take C.being taken D.taking
析:根據this evening,應選表示將來義的選項,C、D應排除。Take後無賓語,必然要用被動式,故答案為A。
4.John was made ______ the truck for a week as a punishment.
A.to wash B.washing C.wash D.to be washing
析:根據be made to do sth.句式,可定答案為A。
5.The patient was warned ______ oily food after the operation.
A.to eat not B.eating not C.not to eat D.not eating
析:根據warn sb.(not)to do sth.句式,可排除B、D兩項;又根據非謂語動詞的否定式not總是在首位的規律,又可排除A,而定C。
6.——I usually go there by train. ——Why not ______ by boat for a change?
A.to try going B.trying to go C.to try and go D.try going
析:此題可根據why not後直接跟原形動詞規律而一舉確定正確答案為D。若將B項改為try to go,則要根據其與try going意義之別來確定答案。依據題乾對話內容,乙方是建議甲方嘗試乘船變變花樣,所以答案仍為D。
7.______ a reply,he decided to write again.
A.Not receiving B.Receiving not C.Not having received D.Having not received
析:非謂語動詞的否定式not應置於首位,B、D皆為錯誤形式。A項不能表達先於decided的動作,只有選C項才表沒收到信在先,決定再寫信在後,所以C為正確答案。
8.Charles Babbage is generally considered ______ the first computer.
A.to invent B.inventing C.to have invented D.having mvented
析:consider表“考慮”意時,其後動詞用doing形式,此處不表“考慮”,而表“認為”,這時consider後作賓語補足語或主語補足語多為to do,to have done,to be等形式。據此可排除B、D兩個選項。又因A表“要發明”意,不合題用,只有C表“發明了”意,才合題用,故選C。
9.Most of the artists ______ to the party were from South Africa.
A.invited B.to invite C.being invited D.had been invited
析:“被邀請參加晚會”,應選表被動意的選項,B不可用。D項少引導詞who,也應排除。又因短暫動詞的現在分詞被動式不可作定語,C也應排除,只有A.invited(=who were invited)才是正確答案。
10.The murderer was brought in,with his hands ______ behind his back.
A.being tied B.having tied C.to be tired D.tied
析:B表主動意,應排除。C表“將要被捆綁”,A表“正在被捆綁”都不合題意,只有D項填入空白才能表達“雙手被反綁著”這一意思,符合題乾情景。再看一類似例句: He came in,(with)his head held high.他昂首走了進來。
