1、2022年高二英語 M5U1 動詞不定式教案 牛津譯林版 一．不定式的五種基本形式 主動 被動 一般式 to do to be done 完成式 to have done to have been done 進行式 to be doing 不定式的否定形式：not to do/ not to have done / not to be doing/ not to be done/ not to have been done 不定式的進行式、完成式和被動式 ①不定式的進行式由to be + V-ing構(gòu)成，用來表示謂語動詞動作發(fā)生時，不定式的動作正在進行。

2、eg. Some students pretended ____________ (read) English when the teacher came in. ②不定式完成式由to have + V-ed構(gòu)成，用來表示動作發(fā)生在謂語動作之前。 eg. --- Is Bob still performing? --- I’m afraid not. He is said __________ (leave) the stage already as he has bee an official. ③不定式的被動式分為一般式被動to be V-ed和完成式被動to have be

3、en V-ed。當不定式的邏輯主語是不定式所表示的動作的承受者時，不定式要用被動語態(tài)。 eg. It is an honour for me_____________ (invite) to the party. The book is said _______________________ (translate) into many languages. All these gifts must be mailed immediately _____ in time for Christmas. A. in order to have received

4、 B. in order to receive C. so as to be received D. so as to be receiving 二. 不定式句法功能 1. 作主語： To find a true friend is difficult. 不定式短語作主語時，可以直接放在句首，但在很多情況下，尤其是在疑問句和感嘆句中，往往放在謂語之后，而用先行代詞it作形式主語 It is difficult to find a true friend. Is it difficult to find a true frie

5、nd? How difficult it is to find a true friend! 不定式作主語常見句型： a) It is + adj. (easy, important, difficult…) + to do sth. b) It is + n. (a pity, a pleasure, one’s duty, a shame) + to do sth. eg. It’s a pleasure to go shopping at weekends. c) It takes/needs/requires + some time (hours, mont

6、hs, days, patience…) + to do sth. eg. It requires patience to be a good teacher. 2. 作表語： 當句子的主語是aim, idea, policy, question, suggestion, wish, task, duty, job, purpose等或者主語是what引導(dǎo)的名詞性從句時，后面可以用不定式做表語，用以說明主語所包含內(nèi)容。 eg. Our most important task now is to make a plan. 注：作表語的不定式都帶to，但當主語部分有實義動詞do時，to可

7、以省略。 eg. The only thing we can do now is wait and see. 3.作賓語 The teacher said “Remember to bring the book tomorrow!” a) 可以直接用不定式作賓語的動詞很多，常見的有：agree, afford, tend, ask, decide, determine, expect, fail, hope, learn, intend, manage, offer, plan, promise, refuse, want, wish等 當復(fù)合賓語中的賓語是不定式時，先用形式賓語i

8、t代替不定式，把不定式置于補語之后，即：主語＋動 詞＋it＋補語＋to do句式,常用動詞有feel, think, find, believe, consider, make等。 如: He feels it his duty to help the poor. I think it difficult to find a true friend. b) 不定式一般不作介詞的賓語，只有少數(shù)介詞如but, except等后面可以跟不定式作賓語。一般情況下作介詞賓語的不定式都帶to，如果but或except前面有do, does, did, to do時，通常省略to。 eg. The

9、 bus hadn’t e. We had no choice but to wait. = We could do nothing but wait. 4. 賓語補足語 在主語+謂語+賓語+賓補句型中，許多動詞都可以接不定式作賓語補足語。 a) 通常作賓語補語的不定式要帶to，常用于以下動詞之后：ask, tell, advise, allow, permit, enable, expect, force, get, like, order, teach, want, invite, wish, beg等 You should get them to help you. 在謂語動

10、詞believe, find, think, feel, consider, suppose, imagine, prove等后面跟to be…作賓補，不跟to do, 有時to be可省略 ??? ①We all believe John (to be) honest. ??? ②I consider him (to be) one of the best teachers of No. 1 Middle School. ??? 但當不定式是完成式時，to不能省略，如：We consider him to have been foolish. b) 以下兩類動詞后跟不定式作賓補時

11、不能帶to ①使役動詞，如：let, have, make等 ②感官動詞，如： see, watch, notice, look at ,listen to ,hear, feel,等 Don’t let the children trouble you. I heard someone open the door. 但當這兩類動詞為被動態(tài)時，不定式就成了主補。作主補的不定式必須加上to His father made him go to bed early. →He was made to go to bed early by his father. 動詞不定式省略to的情況

12、還有： a) would rather, had better, why not do I would rather go swimming. You had better tidy your bedroom. Why not visit your cousin in Japan? b)當兩個動詞不定式由and, or, except, but, than, rather than相連接時，通常情況下第二個to要省略 Do you want to go shopping or watch a film? I decided to write rather than phone.

13、 We had nothing to do but watch TV. =we had no choice but to watch TV. (注：一般情況下作介詞but, except后接to do，但是如果but或except前面有do, does, did, to do時，通常省略to。) 5. 作定語 不定式可以在句子充當后置定語，修飾名詞。 以下幾類情況常用不定式作定語： ①能帶不定式作賓語的動詞，其同源名詞可以帶不定式作定語。常見的有attempt, decision, promise, plan等 eg. He hasn’t kept his promise to

14、 write to his parents regularly. ②常與不定式搭配的形容詞，其同源名詞一般可以用不定式作定語。常見的有ability, determination, anxiety, eagerness等 eg. His eagerness to finish his homework was quite clear. ③序數(shù)詞、形容詞最高級或被only, last, next等修飾的名詞可以用不定式作定語： She was the only person to survive after the earthquake. （Tips: 不定式在作定語時，有時與被修飾的

15、名詞有意義上的主謂關(guān)系、同位關(guān)系、動賓關(guān)系，如果該不定式是不及物動詞，它后面需要加上適當介詞。） Eg. He’s always the first to e and the last to leave. 主謂關(guān)系 I’ve no time to listen to your excuse. 同位關(guān)系 She has a meeting to attend. （動賓關(guān)系=attend a meeting） There’s nothing to worry about. (動賓關(guān)系=worry about nothing) 6. 作狀語 ⒈作目的狀語 ??? (

16、1) ①I stayed there to see what would happen. ??? ②Henry has decided to go to the hospital to be examined by the doctor. ??? (2)有時為了強調(diào)，不定式前可加in order或so as。如： ??? Bob took down my telephone number so as (in order) not to forget it. ??? 有時為強調(diào)目的狀語可把in order to或不定式置于句首，但so as to不能這樣用。在這種句式中不定

17、式部分可轉(zhuǎn)換為so that, in order that,成為目的狀語從句，如： I stayed there in order (so as) to see what would happen. =I stayed there so that (in order that) I could see what would happen. ???⒉作原因狀語 在部分表示感情色彩的形容詞、過去分詞或動詞之后可接不定式，如：astonished, glad, happy, laugh, pleased, sad, smile, sorry, surprised等。 ??? ①We

18、are glad to hear the news. ??? ②I was surprised to see that a three-year-old baby could write so well. ??? 在部分形容詞后接不定式，用主動形式表示被動意義，這種句型中的主語是不定式的邏輯賓語 如：The question raised by the student is difficult to answer. ??? The room is really fortable to live in. ??? 常這樣用的形容詞有: easy, difficult, heav

19、y, light, fortable, fit, impossible等。 ???⒊ 作結(jié)果狀語 ??? We came home after our holiday to find our garden neat and tidy. ??? 不定式作結(jié)果狀語還常用在下列句式中。如： ??? ①so…as to; such…as to ??? I'm not so stupid (a fool) as to put it in writing.我不至于愚蠢到會把它寫下來。 ??? I'm not such a stupid fool as to put it in wri

20、ting. ??? ②enough…to ??? The boy isn’t old enough to go to school. = The boy is too young to go to school. ??? ③only to 用于表示意想不到的結(jié)果 ??? Jane hurried back only to find her mother dying in the hospital. ??? ④too…to ??? I'm too tired to stay up longer. ??? 但在下列結(jié)構(gòu)中，too…to并非是“太……而不能……”之意

21、。如： ??? ①I'm only too glad to have passed the exam.考試及格我太高興了。（too修飾glad to have…，相當 于very） ??? ②We have too much to learn.我們要學(xué)的太多了（不定式作定語）。 ??? 4. 不定式短語還可作獨立成分，用于句首、句中或句末。如： ??? To tell the truth, the play was a great disappointment tome. ??? 常見的短語有to be exact（確切地說），to begin with（首先），to do

22、 him justice（說句對他公道的話），to be sure（真的）等等。 Eg. To tell you the truth, I dislike you. 7. 作同位語 eg. The order to start the general attack soon came. 不定式的復(fù)合結(jié)構(gòu)，以it為形式主語或形式賓語引導(dǎo)的復(fù)合結(jié)構(gòu)，如果其前的形容詞是指行為的性質(zhì)就用：for sb. to do sth.這種復(fù)合結(jié)構(gòu)在句中可作主語、表語、賓語、定語、狀語等。 It is necessary for me to learn English well. 如果該形容詞是指

23、行為的性質(zhì)，同時又指行為的人，則用of sb. to do sth.。這種句式中的常用形容詞有：right, wrong, brave, careful, careless, clever, wise, stupid, cruel, foolish, good, honest, kind, nice, silly等。 eg. It’s very kind of you to e to see me. 連接代（副）詞+不定式（包括whether, what, which, whom, where, when, how, 不包括why），在句中起名詞的作用，通常跟在諸如tell, know,

24、show, decide, learn, wonder, explain等動詞后作賓語,也可作主語或表語。 eg. No one can tell me where to find John. When to start the exam is still unknown. The problem is how to get enough money. 動詞不定式鞏固練習(xí) 1. I've worked with children before, so I know what ________in my new job. A．expected B．to expect　　C
