動詞不定式用法小結(jié)

1、    動詞不定式用法 動詞不定式?jīng)]有人稱和數(shù)的變化，在句中不能獨立作謂語。但動詞不定式具有名詞、形容詞和副詞特征，在句中可以作主語、賓語、賓語補足語、定語、表語和狀語等多種成分。另外，動詞不定式具有動詞特點，可以有自己的賓語和狀語，組成動詞不定式短語。動詞不定式的肯定形式是todo；其否定形式是not todo。 下面以動詞不定式在句中的作用來予以詳細說明。 1作主語 可以直接作主語。如： To see is to believe 但在英語中，常用it作形式主語，真正的主語即動詞不定式放在后面。如： It's wrong to play tricks o

2、n other people It's our duty to keep our environment clean and tidy 點擊規(guī)律：動詞不定式在句中作主語時，常放在It is adj（形容詞）to do sth或 It is n（名詞）to do sth句型中，it僅作形式主語。 2作賓語 awant，decide ，agree等動詞后面跟并且只能跟不定式。如： We agreed to start early She wants to be a doctor blove，like ，begin，start，hate ，prefer等詞后面可以接不定式。 點擊規(guī)律：上述動

3、詞后面除接不定式外，還可以接動名詞，意思無很大區(qū)別。 提示板：like doing指經(jīng)常性動作，而like to do指一次性的動作。如： I like swimming，but I don't like to swim now我喜歡游泳，但我現(xiàn)在不想游。 cstop，forget，remember，go on ，try等詞或短語后面可以接不定式。 點擊規(guī)律：上述動詞后面接不定式和接動名詞意思大不相同。 提示板： 1）stop to do sth：停止一件事，去做另一件事。 stop doing sth：停止正在做的事。 例句：When the teacher came in，the

4、students stopped talking；when he came out，the students stopped to talk 當老師走進來時，學生們停止說話；當老師走出去時，學生們又開始說話。 2）思考：forget，remember，go on，try等詞或短語后面接不定式和動名詞用法有何區(qū)別？ d在findfeelitadjto do sth句型中，it是形式賓語，真正的賓語是后面的動詞不定式。如： The man downstairs found it difficult to get to sleep I feel it easy to recite the text

5、點擊規(guī)律：某些動詞或短語后面既可以接動詞不定式作賓語，又可接動名詞作賓語，二者用法上的區(qū)別可以通過造句子加以區(qū)分，如上面stop例句。 3作賓語補足語 atell，ask，want，order，teach，invite，warn，wish，help，get，wish，help等詞后面常接不定式作賓補。如： I tell him not to go there by bus Edison's mother taught him to read and write blet，make，have，see，hear，feel，watch， notice后面接不帶to的不定式作賓補。如： The

6、 boss makes them work 16 hours a day I heard her sing in the next room 提示板：若變成被動語態(tài)，在上述結(jié)構(gòu)中，不定式符號to要加上。如： They are made to work 16 hours a day by the boss She was heard to sing in the next room 4作定語：放在被修飾的名詞、代詞后面 例句：I have a lot of work to do The doctor said he could do nothing to help the boy 點擊規(guī)律：動詞

7、不定式若在句中作定語，常放在被修飾的名詞、代詞之后。 提示板：如果動詞不定式和前面所修飾的詞構(gòu)成動賓關(guān)系，若動詞是不及物動詞，切記不要忘掉介詞。如： I have a small bedroom to live in Have you got some pens to write with？ 5表語：放在連系動詞be后面 例句：His wish is to become a scientist The first important thing is to save the soldiers' lives 當務之急是搶救戰(zhàn)士們的生命。 點擊規(guī)律：動詞不定式在句中作表語時，通常對連系動詞

8、前面的名詞進行詮釋說明。 6作狀語 a目的狀語：放在go，come，use，live，in order等詞后面。如： I come to see you He runs fast in order to get there in time b原因狀語：放在sorry，glad，surprised， disappointed，excited等詞后面。如： I am glad to see you here I am sorry to trouble you c作結(jié)果狀語。如： Some of the apples are hard to reach The room is large enoug

9、h to hold 1000 people 7與what，who，whose，when，where， how等疑問詞連用，作賓語、賓語補足語、主語等。 如： I don't know what to do next（賓語） He taught us how to use the computer（賓語補足語） It's still a question how to get there（主語）    【模擬試題】（答題時間：30分鐘）    一. 選擇填空：    1. He asked me _
