英語中有一種特殊的動詞,它們沒有人稱和數(shù)的變化,在句子中不能作謂語,我們把這種不能作謂語的動詞稱為非謂語動詞。非謂語動詞主要有動詞不定式、動名詞和分詞三種形式。
1.動詞不定式與動名詞作主語的用法區(qū)別
動詞不定式和動名詞都可在句子中作主語,使用時要注意以下幾點:
(1)動詞不定式表示具體的、特定的行為;而動名詞表示抽象的、一般的行為。如:
To complete the program needs much effort.完成這項計劃需要很大的努力。
Reading is really fun.讀書很有趣。
(2)在疑問句中,只用動名詞的復合結構作主語而不用動詞不定式。如:
Is his speaking reasonable?他的發(fā)言有道理嗎?
(3)在某些句型中通常要用動名詞短語作主語,而不可用不定式代替。如:
It is no use doing .../It is no good doing .../It is useless doing .../It is worthwhile doing ...等。如:
It is no use talking your trouble to a man like him.跟他那樣的人談你的煩惱沒有用。
(4)一般說來,作主語和表語的非謂語動詞形式應一致,即:表語為不定式時,主語也用不定式;表語為動名詞,主語也用動名詞形式。如:
Seeing is believing.眼見為實。
但是,在現(xiàn)代英語中,當表語用來說明主語的特定意義或具體內(nèi)容時,主語和表語的非謂語動詞的形式可以不一致,即,主語用動名詞,而表語用動詞不定式。如:
Waving your hand is to say “Good-bye”.揮手就是說“再見”。
Nodding your head is to say “Yes”.點頭就是說“對,是的”。
2.動詞不定式與動名詞作賓語的用法區(qū)別
動詞不定式和動名詞都可以作及物動詞的賓語,它們往往受到謂語動詞的限制。有些動詞只接動詞不定式作賓語;有些動詞只接動名詞作賓語;還有一些動詞既可以接動詞不定式作賓語,也可以接動名詞作賓語,但意義有差別。
(1)只接動詞不定式作賓語的動詞
后只跟動詞不定式作賓語的常用動詞有:want,decide,ask,offer,promise,hope,wish,help,learn,refuse,expect,plan,agree,prepare等。如:
I want to go swimming this afternoon.今天下午我想要去游泳。
They decided to build a bridge over the river.他們決定在河上面建一座橋。
The letter asked people to give up nuclear weapons.這封信請求人們放棄核武器。
Her parents are planning to have their second child.她父母正計劃要第二個孩子。
I hope to go with you.我希望和你一起去。
My mother refused to go there with us.我媽媽拒絕和我們一起去那里。
My English teacher promised to lend some books to me.我的英語老師答應借給我一些書。
(2)只接動名詞作賓語的動詞及動詞短語
后只跟動名詞作賓語的常用動詞有:finish,enjoy,spend,mind,keep,suggest,practice,admit,advise,allow,avoid,consider,discuss,escape,imagine,mention,miss,prevent,put off,give up,insist on,be worth,keep on,look forward to,can't help,be/get used to,can't stand,feel like 等。如:
You shouldn't keep thinking about it.你不應老想著這事。
Would you mind opening the window?打開窗好嗎?
Everyone in my class enjoys playing football.我班人人喜歡踢足球。
We only missed seeing each other by five minutes.我們只因差五分鐘而未能見面。
I advise waiting a few more days.我建議再等幾天。
I admit breaking the window.我承認窗子是我打破的。
These books are well worth reading.這些書值得讀。
My mother couldn't help smiling when she heard the good news.聽到那好消息,我媽媽情不自禁地笑起來。
My father has given up smoking.我父親戒煙了。
Do you feel like taking a walk?你要不要去散步?
We are looking forward to coming to China.我們期待著來中國。
(3)既可以接動詞不定式也可以接動名詞作賓語的動詞,分為以下幾種情況:
①后跟動詞不定式和動名詞作賓語意思相同,使用上無多大差別的動詞有:begin,start,continue等。如:
We began learning/to learn English when we came to junior middle school.我們來初中時才開始學習英語。
注意:
①begin,start 用于進行時態(tài)時,后面的非謂語動詞只用動詞不定式而不用動名詞。如:
He is beginning to work in that company.他即將開始去那個公司工作。
②begin,start后面的非謂語動詞如果是表示心理活動方面的動詞know,love,like,understand,hate,enjoy等時,只用動詞不定式,而不用動名詞。如:
After the talk with his English teacher,he began to like English.跟英語老師談話之后,他開始喜歡英語了。
②forget,remember,regret等動詞,后跟動詞不定式作賓語表示“要干某事”,動詞不定式所做的事情還沒做;后跟動名詞作賓語表示“干過某事”,即動名詞所做的事情為過去所為。如:
I forgot to tell you about it.我忘記要告訴你那件事了。
I remembered giving the book to Li Lei,but he said I didn't.我記得我把書給李雷了,但是他說我沒有給。
③hate,like,love,prefer等動詞,接不定式作賓語時通常表示一次性或具體動作;接動名詞作賓語時,通常表示一般性或習慣性的動作。但在現(xiàn)代英語中,通常不加區(qū)別地混用。如:
I hate to go boating today.今天我不想去劃船。
I hate going boating.我討厭劃船。
④動詞mean接不定式作賓語時,表示一種意圖,意為“打算做,想要做”;接動名詞作賓語時表示解釋,意為“意味著,意思是”。如:
I didn't mean to bother you.我本不想打擾你。
What he said means going there by air.他說的話意思就是坐飛機去那兒。
⑤try后接不定式作賓語時,表示一種決心,意為“設法做;盡力做”;后接動名詞作賓語時,表示沒有把握,意為“試著做”。如:
I'll try to catch up with my class this term.這一學期我將盡力趕上同學們。
Why didn't you try riding a bike to go to school?為什么不試著騎車去學校呢?
⑥stop,go on等,后接不定式作賓語時表示一種目的,表示停下來或繼續(xù)的目的是要去干另一件事;接動名詞作賓語時,表示停止或繼續(xù)所做的事情,意為“停止干某事或繼續(xù)干某事”。如:
Now stop to listen to me,please.現(xiàn)在請停下來聽我講。
Now stop writing,please.現(xiàn)在請停止寫字。
⑦need,require,want等動詞,后接不定式作賓語時,非謂語動詞的動作為句子的主語所發(fā)出,即句子的主語與非謂語動詞有邏輯上的主謂關系;接動名詞作賓語時,非謂語動詞的動作為句子的主語所承受,即句子的主語與非謂語動詞在邏輯上是動賓關系,有被動的意味。如:
I need to water the flowers every day.我需要每天給花澆水。
The flowers need watering every day.=The flowers need to be watered every day.花兒需要每天澆水。
⑧can't help后接不定式作賓語時,意為“不能幫忙干”;接動名詞作賓語時,意為“禁不住干,情不自禁干”。如:
I'm very busy now,so I can't help (to)clean the room.我現(xiàn)在很忙,因此不能幫助打掃房間了。
The girl couldn't help crying when she saw her mother again.當小女孩再次看到母親時,她情不自禁地哭了起來。
⑨be used to后接不定式時,意為“被用來做某事”;接動名詞作賓語時,意為“已習慣于做某事”。如:
The wood will be used to make paper.這些木材將被用來造紙。
My parents are used to getting up early.我父母已習慣于早起床。
3.動詞不定式、動名詞、分詞作表語的用法區(qū)別
(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;動名詞作表語,表示抽象的一般性的行為。
What I would suggest is to start work at once.我的建議是立刻開始干。
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。
(2)表示心理狀態(tài)的及物動詞如excite,interest,bore,surprise,frighten,disappoint等,當主語是表示人的名詞時,用分詞形容詞即-ed形容詞作表語;當主語是表示事物的名詞時,用-ing形式作表語。
The boy was excited at the news.那個男孩為這個消息感到興奮。
The activity is very exciting.那項活動令人興奮。
I'm interested in collecting all kinds of concert tickets.我對收集各種各樣的音樂會門票感興趣。
The film is so interesting.這部電影如此有趣。
4.動詞不定式、動名詞、分詞作賓語補足語的用法區(qū)別
(1)動詞不定式作賓語補足語,強調(diào)動作的全過程,表明動作已經(jīng)結束或即將發(fā)生;動名詞作賓語補足語,強調(diào)動作正在進行;過去分詞作賓語補足語時,及物動詞的過去分詞表示完成和被動,不及物動詞的過去分詞只表示完成。如:
I often see him go to the cinema.我經(jīng)??匆娝タ措娪?。
I found a strange person walking nearby our shop all day.我發(fā)現(xiàn)一個陌生人整天在我們商店附近走動。
He spoke slowly to make himself understood better.他說得很慢,讓自己更好地被人理解。
(2)下列動詞只用動詞不定式作賓語補足語,組成“動詞+sb.+to do”結構,而不用動名詞或分詞作賓語補足語。
ask sb.to do sth.要求某人干某事 tell sb.to do sth.告訴某人干某事
advise sb.to do sth.建議某人干某事 allow sb.to do sth.允許某人干某事
encourage sb.to do sth.鼓勵某人干某事 expect sb.to do sth.期望某人干某事
help sb.to do sth.幫助某人干某事 wish sb.to do sth.希望某人干某事

My parents don't allow me to swim in the river.我父母不允許我在河里游泳。
Father encourages me to do what I like.父親鼓勵我做我所喜歡的事情。
注意:
動詞不定式作賓語補足語時,在動詞make,let,have,see,notice,hear,watch,feel等后面要省略不定式符號to;help后的動詞不定式作賓語補足語時,不定式符號to可加可不加。如:
The teacher made him do the exercises again.老師讓他再做一次練習。
He often helps me (to)study English in his spare time.他經(jīng)常在課余時間幫我學英語。
5.動詞不定式、動名詞、分詞作定語的用法區(qū)別
動詞不定式、動詞的-ing形式和動詞的-ed形式皆可作定語,用法和意義差別較大。
動詞不定式作定語,只能置于被修飾詞的后面,往往表示未發(fā)生的情況;形容詞性的-ing形式作定語置于被修飾的名詞或代詞前,單個的動作性-ing形式常放在被修飾的名詞前,動作性的-ing形式的短語常置于被修飾的名詞后,往往表示正在進行的行為;單個的-ed形式作定語常置于被修飾詞前,-ed修飾的短語常置于被修飾詞之后,表示被動和完成。
動詞不定式作定語時,當所修飾的名詞指人時,不定式與它所修飾的名詞之間有邏輯上的主謂關系;當不定式所修飾的名詞指物時,不定式與它所修飾的名詞之間有邏輯上的動賓關系;動名詞作定語時,動名詞與它所修飾的名詞之間沒有邏輯上的主謂關系,只表示被修飾名詞的一般用途;現(xiàn)在分詞作定語時,現(xiàn)在分詞與它所修飾的名詞之間有邏輯上的主謂關系,表示所修飾名詞的特征;
I have a meeting to attend .我有一個會議要出席。
There is a swimming pool in our school.在我們學校有一個游泳池。
Listen to the singing bird.聽那只鳥在唱歌。
Who is the boy running towards us?朝我們跑來的那個男孩是誰?
The worried mother has been ill for days.憂心忡忡的媽媽病了好幾天了。
Most of the people invited to the party were famous scientists.大多數(shù)應邀參加這次晚會的人是著名的科學家。
6.動詞不定式、動名詞、分詞作狀語的用法區(qū)別
動詞不定式作狀語通常表示目的、原因和結果;動詞的-ing形式和-ed形式作狀語主要表示原因、時間、結果、條件、方式、讓步及伴隨情況。如:
He went to the library to borrow a book.他去圖書館借了一本書。(表目的)
The boy sat at the desk reading a book.那個男孩坐在課桌旁看書。(表伴隨情況)
Seen from the top of the hill,the park looks more beautiful.從山頂上看去,這個公園顯得更加美麗。(表方式)
