  三、非謂語動詞 不定式(to + V)

  動名詞

  分詞-ing

  分詞-ed

  (一)動詞不定式(to+動詞原形)轉自環 球 網 校edu24ol.com

  動詞不定式的語法功能

  可以做除謂語動詞以外的任何句子成分。

  1)作主語

  不定式或不定式短語作主語時,謂語動詞用第三人稱單數。如:

  To serve the people well is our duty.

  動詞不定式短語作主語時,往往放在謂語動詞的后面,用引導詞it作形式主語。上述句子也可改為:

  It is our duty to serve the people well.

  類似這樣不定式做主語的句型有:

  It is + n.+ to do

  It takes sb.+ some time + to do

  It is +adj.+ for sb.+ to do

  It is + adj.+ of sb.+ to do

  例如:

  It is our duty to help them.

  It will take you quite a long time to finish it.

  It is easy for us to answer this question.

  It is kind of you to help me.

  注:

  1)for sb.常用于表示事物的特征特點,表示客觀形式的形容詞,如easy, hard, difficult, interesting, impossible等:

  2)of sb.的句型一般表示人物的性格,品德,表示主觀感情或態度的形容詞,如good, kind, nice, clever, foolish, right等。

  2)作賓語

  We hope to have more opportunities to talk with native speakers.

  注意:

  如果不定式作賓語而又跟有補語,這時,通常要用"it"作形式賓語,而將不定式放到補語后面去。

  例如:

  他們發現提前把一切都準備好是不可能的。

  ×They found to get everything ready in advance impossible.

  賓語 賓補

  ×They found to get everything ready in advance is impossible.

  √They found it impossible to get everything ready in

  賓補 賓語

  advance.

  再看下面的兩個例句:

  I consider it my duty to point out their shortcomings.

  Robert doesn't think it advisable for Mary to be on a diet.

  三級出題方式:

  I _____ to point out their shortcomings.

  A.consider it my duty

  B.consider it is my duty

  3)作定語

  This is the best way to solve the problem.

  注意:

  ①用不定式作定語時,它與它所修飾的詞有時是動賓關系,所以如果不定式是不及物動詞,其后面應跟上必要的介詞。

  例如:

  Mary needs a friend to play with.

  There is nothing to worry about.

  Because air pollution has been greatly reduced, this city is still _____ .

  A.a good place to live

  B.a good place for living in

  C.a good place to be lived in

  D.a good place to live in

  答案:D

  ②不定式作定語,如果與他所修飾的詞是動賓關系,則不定式后面不能再帶賓語。

  例如:

  ×Here is a letter for you to type it.

  √Here is a letter for you to type.

  ×The smell tells the bees what kind of flowers to look for them.

  √The smell tells the bees what kind of flowers to look for.

  同時要注意:在這類結構中,常用不定式的主動式代替被動式。

  4)作狀語

  In order to overcome difficulties, we must work hard.

  注意:轉自環 球 網 校edu24ol.com

  ①不定式能夠修飾作表語或賓語補足語的形容詞,在句中作狀語,這時不定式不能再帶賓語。

  例如:

  √The water is unfit to drink.

  ×The water is unfit to drink it.

  √They found Mr.Jones' lecture hard to understand.

  ×They found Mr.Jones' lecture hard to understand it.

  同時要注意:在這類結構中,常用不定式的主動式代替被動式。

  ②作狀語的不定式的邏輯主語必須與句子主語一致。

  例如:

  ×To save money, the bus was taken instead of plane.

  √To save money, we took the bus instead of plane.

  讓我們看一道2005年11月份的三級試題:

  To succeed in a scientific experiment,______.

  A.one needs being patient person.

  B.patience is to need.

  C.one needs to be patient.

  D.patience is what needed.

  答案:C

  2.不定式的邏輯主語

  如要表明不定式或不定式的動作發出者(即邏輯主語),就要在不定式前用for+名詞(或代詞的賓格)。如:

  Is the road wide enough for two cars to pass?

  The conference is too important for you to miss.

  3.不定式的時態和語態

  不定式有一般、完成、進行等幾種常用的形式,也有主動和被動語態的區別。以study為例:

  主動/被動一般式to study; to be studied

  進行式to be studying

  完成式to have studied; to have been studied

  1)不定式的時態

  不定式的一般式(to do)所表示的動作與謂語動詞所表示的動作是同時發生,或是在其后發生的。如:

  Thousands of young people are learning to ski.

  不定式的進行式(to be doing)所表示的動作與謂語動詞的動作是同時進行的,而且是正在進行的。如:

  They seemed to be getting along quite well.

  不定式的完成進行時(to have done)表示限于謂語動詞之前發生的動作或狀態,to have + V-ed 表示動作,to have been 表示狀態。如:

  She seems to have finished her work.

  不定式的完成進行時表示動作在謂語動詞之前發生,而且一直進行著。如:

  She was happy to have been staying with her aunt.

  2)不定式的語態

  每個不定式都有其邏輯主語,如果邏輯主語是動作的發出者,不定式用主動式,如果其邏輯主語是動作的承受者,不定式用被動式。如:

  The doctor recommended him to air the room.

  醫生建議他打掃房間。

  The doctor recommended the room to be aired.

  醫生建議打掃房間。

  考試重點:使用不帶to的不定式的幾種情況

  (1)在口語中,以why開頭的簡單問句中。例如:

  Why do it that way?

  Why not go out for a walk?

  (2)某些使役動詞,如make, let,have等后面跟動詞不定時作賓語補足語時,用省略to的不定式。如:

  Let him do it.讓他做吧。

  I would have you know that I am ill.我想要你知道我病了。

  (3)表示生理感覺的動詞后接不定時作賓語補足語時,不定式不帶to.這類詞有:

  feel 覺得 observe 注意到,看到 hear聽到

  watch注視 listen to聽 perceive察覺,感知

  notice注意 see看見 look at看]

  注意:

  表示 "感覺"的動詞,既可以用不帶to 的不定式作賓語補足語,又可以用現在分詞作賓語補足語,但兩者有含義上的差別。現在分詞作這些動詞的賓語補足語,表示動作的進行,以不帶to的不定式作這些動詞的賓語補足語,表示動作的完成。

  例如:

  I heard her playing the violin.

  我聽到她在拉小提琴.

  I don't see the ball break the window.

  我沒有看到球砸壞玻璃.

  注意:

  上述使役動詞與感覺動詞轉換為被動結構時,其后的不定式需帶to,如:

  He was seen to come.

  The boy was made to go to bed early.

  (4)在do nothing/anything/everything but(except)結構中。例如:

  Last night I did nothing but watch TV.

  昨天晚上,除了看電視,我什么也沒干。

  但是,如果謂語動詞不是"do nothing,anything,everything",那么but(except)所跟的不定式則仍須帶to.

  The doctor told him nothing but to stop smoking.

  醫生除了讓他戒煙,其它什么都沒有說。

  There was nothing for them to do but remain silent.

  除了保持沉默以外,他們沒有別的辦法。

  記憶口訣:

  前面有do,后面省to,前面無do,后面帶to.

  (5)下面這些詞組是不定式的習慣用法,只能用省to的不定式形式。

  can not help but do(不得不)

  can not but do(不得不)

  cannot choose but do(只能)

  have no choice but do (只能)

  had better do(最好
