非謂語動詞是指分詞（包括現在分詞和過去分詞）、不定式、動名詞等三種形式，即：

doing , done , to do , doing 。當然它們有各自不同的變化形式，如：

現在分詞 doing : 有being done（被動式） ; having done （完成式）; having been do

ne （完成被動式）

不定式 to do : 有to be done （被動式）; to have done （完成式）; to be doing（進行式）

動名詞 doing : 有having done（完成式）; being done（被動式） ;

非謂語動詞的特點： 三種非謂語動詞都具有動詞的特征，雖然它們沒有人稱和數的變化，但是它們都能帶自己的狀語或有時跟賓語。它們都有各自的特征：分詞具有形容詞和副詞的特征；動名詞具有名詞的特征；不定式具有名詞、形容詞和副詞的特征。具體來講：分詞在句子中可以做定語、表語、狀語或補足語等；動名詞在句子中可以做主語、賓語、表語等；不定式在句子中可以做主語、賓語、表語、補足語或狀語。

下面分別對三種非謂語動詞進行講解：

一． 動詞不定式

先看幾個例句，判斷不定式在句中的成分。

1．To learn a foreign language is difficult .

2． His wish is to be a driver .

3．Tom wanted to have a cup of beer .

4．The teacher told us to do morning exercises .

5．I have nothing to say .

6．They went to see their aunt .

7．It’s easy to see their aunt.

8．I don’t know what to do next .

9．I heard them make a noise .

說明：1．動詞不定式作主語, 2.動詞不定式作表語,3.動詞不定式作賓語,4．動詞不定式作賓語補足語，5．動詞不定式作定語,6．動詞不定式作目的狀語,7．動詞不定式作真正主語，it 代替動詞不定式，作形式主語。8．帶有連接代詞的動詞不定式作賓語,9．不帶to 的動詞不定式作賓語補足語。

掌握動詞不定式應注意的幾個問題：

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 .

It’s necessary for you to study hard .

It’s foolish of him to do it .

與of 連用的形容詞有：

good, kind , nice , wise ,clever , foolish , right , wrong , careful , careless , polite , possible

4．后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 , o

ught to , need to , used to , be able to

6．不定式作定語，應注意兩種關系：

1）動賓關系：

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）主謂關系：

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

注: 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.

二．動名詞

Learning English is very difficult .

學英語非常困難。

His job is driving a bus .

他的工作是開車。

I enjoy dancing .

我喜歡跳舞。

I have got used to living in the country .

我已經習慣了住農村。

Take some sleeping tablets , and you will soon fall asleep .

吃點安眠藥，你很快就會入睡。

注意以下幾種結構：

1．There’s no telling what will happen .

=It’s impossible to tell what will happen .

= No one can tell what will happen .

2．It’s no use talking with him .

It’s no good speaking to them like that .

3．There’s some difficulty ( in ) doing …

在此句型中,difficulty 可以由以下單詞替換:

trouble , problem , fun , pleasure , a good time , a hard time

注意以下幾個問題：

1．下列動詞后跟不定式與跟動名詞作賓語意義有區別，

forget to do … 忘記要做某事

forget doing… 忘記做了某事

remember to do…記住要做某事

remember doing …記著做了某事

mean to do … 有意要做某事

mean doing … 意味著做了某事

regret to do … 對要做的事表示后悔

regret doing … 對做過去的事后悔

can’t help to do…不能幫助做某事

can’t help doing … 情不自禁做某事

try to do … 盡力去做某事

try doing 試著做某事

learn to do … 學著去做某事

learn doing … 學會做某事

stop to do … 停下來去做（另一件事）

stop doing … 停止做某事

go on to do … 接著做（另外一件事）

go on doing … 繼續做某事

used to do … 過去做某事

be used to doing … 習慣做某事

2．動名詞作定語與現在分詞作定語意義有區別

動名詞作定語表達 n+ for doing 的含義

現在分詞作定語表達 n+which(who) be doing的含義

如：a sleeping car = a car for sleeping

a running horse = a horse which is running

前者是動名詞 ， 后者是現在分詞

又如： drinking water , walking stick running water , sleeping boy

3． 動名詞的邏輯主語：

動名詞的邏輯主語為代詞或名詞的所有格形式。

例如：His coming made us very happy .

4．動名詞的語態和時態

5． 動名詞主動形式表被動的情況：

need doing , want doing , require doing

例如： This room needs painting . 這個房間需要粉刷。

6．只能跟動名詞作賓語的動詞：

admit , avoid , advise , consider , delay , deny , enjoy , escape , excuse , fancy , finish , complete , forbid , imagine , mind , miss , permit . practise , require , suggest , risk , keep, take to , look forward to , get down to , feel like , can’t help , can’t stand , be used to ,insist on , succeed in , set about, give up , include ,

三． 分詞

1 The story is interesting . I’m interested in it .

這個故事有興趣，我對這個故事感興趣。

2 . This is a moving film .

這是一部動人的電影。

3. The secretary worked late into the night , preparing a long speech for the president .

秘書工作到深夜，為主席準備一篇長篇演講稿。

4. Given more time , I’ll do it well .

如果給我多一點時間，我會做的更好。

When he passed the back of the street , he saw the thief stealing some money from the bank .

當他后街時，看到小偷正從銀行偷錢。

應注意的幾個問題：

1．現在分詞與過去分詞的區別

Do you know the woman talking to Tom ?

= Do you know the woman who is talking to Tom ?

The soldier wounded in the war has become a doctor.

= The soldier who was wounded in the war has become a doctor.

China is a developing country and America is a developed country.

2．分詞作表語

The news sounds encouraging .

They got very excited .

1）現在分詞與過去分詞作表語的區別：

The news is interesting .

He is interested in the news .

doing 作表語，主語與表語是主謂關系 ；done 作表語，主語與表語是動賓關系。

2）表語與被動式的區別：

The blackboard was broken by Xiao Ming .（強調動作）

The blackboard is broken . You’d better have it repaired.（強調狀態）

3）常作表語的過去分詞：

amused , injured , covered , known , dressed , lost , broken , gone , delighted, excited , pleased , satisfied , married , worried , surprised , interested , burnt , shut , crowded , wounded , drank , done

3．現在分詞、動名詞 現在進行時的區別

The situation in our country is encouraging . (表語)

The situation in our country is encouraging the people . ( 現在進行時)

My job is looking after the little baby . (動名詞)

能回答how-question 的是現在分詞，能回答what-question 的動名詞，即不能回答how-question 也不能回答what-question 的是現在進行時。

例如： How is the situation in our country ? It is encouraging .

What is your job ? My job is looking after the little baby .

4．注意的四種結構：

have something to do 有某事要做

have something done 使某事被做

have somebody do something 使某人做某事

have something doing 讓某事一直做著

5． 需要跟反身代詞作賓語的動詞：

seat , prepare , hide , dress

如：I seated myself on the chair .

I was seated on the chair .

6．分詞做狀語與不定式的區別：

分詞做狀語表示時間、原因、讓步、 條件、方式、伴隨等；而不定式表示目的和結果。

Having finished the homework , I went home . （ 時間）

Being a Party member , I should work hard . （原因）

Given more time ,I can do my work better . （ 條件 ）

He ran out of the classroom ,shouting at the boy. （ 伴隨）

To get more knowledge , we must work harder and harder . ( 目的 )

He is old enough to join the army . （ 結果）

7．分詞、動名詞和不定式作定語的區別

a running horse 現在分詞 = a horse that is running

a fallen leaf 過去分詞 = a leaf that has already fallen

a walking stick 動名詞 = a stick for walking

something to do 不定式 = something that I should do

8．不定式被動式、分詞的被動式和過去分詞的區別：

I have a problem to be discussed at the meeting . ( 將來)

The building being built on the river is the Science Museum . （正在進行）

The building completed three years ago is now in bad conditions . （ 過去）

9．分詞做狀語需要注意的一個問題：

分詞與句子主語的邏輯關系

Seeing from the hill , the city looks beautiful .( 錯誤 )

Seen from the hill , the city looks beautiful . （ 正確）

Seeing 與the city 不是主謂關系；seen 與city 是動賓關系
