文檔簡(jiǎn)介
1、文檔供參考,可復(fù)制、編制,期待您的好評(píng)與關(guān)注! 非謂語(yǔ)動(dòng)詞不定式的句法功能:動(dòng)詞不定式除了不能單獨(dú)作謂語(yǔ)外,幾乎能充當(dāng)句子中所有的句子成分。1.不定式做主語(yǔ):(1) To finish the work in ten minutes is very hard. 動(dòng)詞不定式(短語(yǔ))作主語(yǔ)時(shí),常用it代替它作形式主語(yǔ): It is very hard to finish the work in ten minutes. (2)不定式和動(dòng)名詞做主語(yǔ)的區(qū)別: 動(dòng)名詞做主語(yǔ)往往表示普通的、一般的行為,在意義上是比較抽象的、一般的,時(shí)間概念不強(qiáng),不是指某一次的動(dòng)作;不定式做主語(yǔ)常表示某次具體的行為。 例如
2、: Doing sports is good for peoples health. To do too much exercise is not good for him as he has a heart illness.2.不定式作表語(yǔ)(1)表示主語(yǔ)的具體內(nèi)容。The duty of a postman is to deliver letters and newspapers.注意:主語(yǔ)部分有實(shí)義動(dòng)詞do 時(shí),表語(yǔ)中可以省略to。 What he did first was (to) walk up to his friend and hug him. (2)“be to do”還可以表
3、示不同的情態(tài)意義。 Children are not to smoke. (禁止)They are to marry next week. (安排)You must be patient and persistent if you are to succeed. (愿望) Man is to live a better life in the next century. (事態(tài)發(fā)展或預(yù)期的結(jié)果)注意:有幾個(gè)不定式作表語(yǔ),需用主動(dòng)表被動(dòng):Parents are to blame if their children do not have good manners. 3.不定式做賓語(yǔ)(1)接不定式
4、做賓語(yǔ)的常見(jiàn)動(dòng)詞:afford, agree, aim, appear, arrange, begin, choose, come, dare, decide, demand, desire, determine, expect, fail, happen, help, hope, learn, long, manage, offer, plan, prepare, pretend, promise, refuse, seem, tend, want, wish 注意: demand/hope只能接to do 不能接sb to do。 (2)一些動(dòng)詞要用疑問(wèn)詞+不定式作賓語(yǔ)。 常見(jiàn)的動(dòng)詞有:d
5、ecide, know, learn, wonder, find out, remember, see 等。 I dont know how to do it. I havent decided whether to sell it or not. (3)feel, find, judge, make, think, believe, consider等動(dòng)詞后如果是不定式作賓語(yǔ),補(bǔ)語(yǔ)是形容詞(間或是名詞),常用it 作形式賓語(yǔ),把不定式后移。I thought it a great pity not to have invited her. I find it hard to work wit
6、h him. (4)在表示“希望、打算”等動(dòng)詞(如hope, expect, intend, mean, want等)的過(guò)去式后,可接動(dòng)詞不定式的完成式來(lái)表示沒(méi)有實(shí)現(xiàn)的動(dòng)作。 We meant to have stayed there a week. (= We had meant to stay there a week.)(5)在介詞but 和except后的動(dòng)詞形式:在這種句式中,如介詞前有實(shí)義動(dòng)詞do, 后面接不帶to的不定式;如果是其他動(dòng)詞, 則接帶to不定式。 On that rainy night I had nothing to do but stay in my car. H
7、e didnt say a word but to listen. (6)作形容詞的賓語(yǔ)句子的主語(yǔ)是不定式的邏輯主語(yǔ)。 John was happy to be given the job.句子的主語(yǔ)是不定式的邏輯賓語(yǔ)。 This problem is easy to solve.She is hard/difficult to get along with.The chair is comfortable to sit on. He is pleasant to work with.
8、 即在easy, hard, difficult, pleasant, interesting等形容詞后的不定式用主動(dòng)形式表示被動(dòng)含義。4.不定式作賓語(yǔ)補(bǔ)足語(yǔ)(1)v.+ sb.+ to do 常見(jiàn)動(dòng)詞:allow, ask, advise, beg, cause, encourage, expect, forbid, force, get, order, permit, persuade, teach, tell, want, warn, wish(2) v.+sb./sth.+ to bebelieve, consider, find, feel, imagine, judge, know
9、, prove, think, suppose, understandHe judged her to be a thief. (3) v.+ sb./sth. + do 感覺(jué)動(dòng)詞和使役動(dòng)詞與不帶to的不定式連用, 但這種句式在變?yōu)楸粍?dòng)語(yǔ)態(tài)時(shí)應(yīng)帶to。如see, watch, notice, hear, make, have, let等。Though he had often made his little sister cry, today he was made to cry by his little sister.(4) help sb. (to) do Id like to help
10、 him ( to ) work out the problem. 5.不定式作定語(yǔ)(1)不定式可以修飾作主語(yǔ)的名詞,相當(dāng)于一個(gè)定語(yǔ)從句,表明動(dòng)作即將發(fā)生。The conference to take place next month will certainly be a great success. (= The conference which will take place)(2)動(dòng)詞不定式作定語(yǔ),放在所修飾的名詞或代詞后。與所修飾詞有如下關(guān)系:動(dòng)賓關(guān)系。I have much to do. I have a question to ask. 如果該不定式是不及物動(dòng)詞,其后應(yīng)有必要的介
11、詞。She has a big house to live in. The lonely man has no one to talk to. 但:She has no place to live.主謂關(guān)系。此時(shí)被修飾詞常為:the first, the second, the last, the best, the only thing 等常跟不定式作定語(yǔ)。He is always the first to come. He is the only one to pass the exam. 同位關(guān)系。表示被修飾詞的具體內(nèi)容。 I lost the opportunity to give m
12、y opinion on it.Some children had no chance to go to school. 6.不定式做狀語(yǔ)(1) 表示目的。不定式作目的狀語(yǔ)時(shí),其動(dòng)作發(fā)生在謂語(yǔ)動(dòng)詞所表示的動(dòng)作之后,一般放在句子后部。但如要表示強(qiáng)調(diào),也可以位于句首,前面可加in order, 但不能用so as。其否定式不能用not + to do, 必須用in order not + to do 或so as not to do。I opened the window to let some fresh air in. In order to catch the train, they too
13、k a taxi. Lets hurry so as not to be late for the meeting.注意:在英語(yǔ)中,目的一般用不定式表示,不用for + doing這一形式。We eat to live. (不用for doing)(2) 作結(jié)果狀語(yǔ)。What have I said to make you so angry?不定式表示結(jié)果常見(jiàn)于下列句型:only to do; so as to do; such as to do; enough to do; too to do。 The news reporters hurried to the airport, only
14、to be told the film stars had left. (表示該結(jié)果出乎意料)Would you be so kind as to help me carry the big bag for me?下列形容詞是對(duì)人進(jìn)行表?yè)P(yáng)或批評(píng)的,后面常接不定式表示結(jié)果: nice, polite, generous,kind, selfish, silly等。 You were silly not to have locked your car.He is generous to lend us a large sum of money.(3)表示原因。常表示引發(fā)某種情緒的原因。 Im ha
15、ppy to see that. We were surprised to hear the news. (4)表明說(shuō)話(huà)人的態(tài)度,在句中作獨(dú)立成分。To tell you the truth, I dont like the way he talked.三、動(dòng)詞不定式的邏輯主語(yǔ)1.句子的主語(yǔ)就是不定式的邏輯主語(yǔ)。 I have much to do. 2.當(dāng)句子的主語(yǔ)不是不定式的邏輯主語(yǔ)時(shí),需要加上邏輯主語(yǔ)。在Its + adj. + for sb. to do sth.結(jié)構(gòu)中,形容詞往往表示事物的性質(zhì)。It is important for us to study English. It i
16、s easy for us to get the latest information. 在 Its + adj. + of sb. + to do sth.結(jié)構(gòu)中,形容詞通常表示人物的性格和特征。Its nice of you to give me so much help. (=You are nice to give me so much help.) 四、補(bǔ)充句型1.主語(yǔ)+ be said/reported/believed/thought/considered+to do He is said to have traveled to many countries. (= It is
17、said that he has travelled to many countries.)This pop group is believed to be the best of this year. (= It is believed that this pop group is the best of this year.) 2.

18、e plane to Mexico, so he escaped being killed in the plane crash.完成式:having done / having been doneHaving studied computer is an important qualification for the job.否定式:not + 動(dòng)名詞二、動(dòng)名詞的句法功能動(dòng)名詞具有名詞詞性, 在句子中可以作主語(yǔ)、賓語(yǔ)、表語(yǔ)和定語(yǔ)。1.作主語(yǔ)Shaking ones head means “no” and nodding means “yes”.動(dòng)名詞作主語(yǔ),有時(shí)也會(huì)用it 作形式主語(yǔ):Its
19、 no use crying over spilt milk. Its no good drinking too much alcohol. 2.作表語(yǔ) My job is teaching. Your task is learning English well. 一般,主語(yǔ)與表語(yǔ)可互換。Teaching is my job.Learning English well is your task.3.作賓語(yǔ)(1) 動(dòng)詞賓語(yǔ):有些動(dòng)詞后加動(dòng)詞的動(dòng)名詞形式作賓語(yǔ)。 常見(jiàn)動(dòng)詞包括:admit, advise, allow, appreciate, avoid, consider, delay , de
20、ny, enjoy, escape, encourage, finish, forbid, imagine, keep, mention, mind, miss, practice, permit, resist, risk, suggest, understand 等,其中有些可用sb./sth. doing 結(jié)構(gòu)。注意其中advise, allow, forbid, encourage, permit可用不定式作賓語(yǔ)補(bǔ)足語(yǔ)。We dont allow smoking in the office.We dont allow them to smoke in the office.主語(yǔ)+nee
21、d/want/require doing , 意思是 “主語(yǔ)需要被” The flowers want watering. ( =The flowers want to be watered.)Our house needs repairing. ( = Our house needs to be repaired.)有些動(dòng)詞后面既可以接動(dòng)名詞,也可以接不定式作賓語(yǔ)。意義基本相同的: begin, continue, start, love, like, hate, prefer, stand意義不同的:forget, remember, regret, stop, go on, try, m
22、ean, cant help(2)動(dòng)詞短語(yǔ)的賓語(yǔ)be busy, be worth,cant help, end up,feel like, give up等。(3)介詞短語(yǔ) spend time (in) doing sth, have difficulty/ trouble (in) doing sth, have a hard time (in) doing sth注意:下列短語(yǔ)中的to是介詞,而不是動(dòng)詞不定式符號(hào),因此后面要接動(dòng)詞的動(dòng)名詞形式。 be used to, devote oneself to, get down to, lead to, look forward to, m
23、ake a contribution to, object to, pay attention to, prefer doing to doing ,stick toMrs. Wang devoted herself to protecting wildlife.Im looking forward to hearing from you.4.作定語(yǔ)表示被修飾詞的用途a walking stick, a washing machine, a waiting room, a dressing mirror三、動(dòng)名詞的邏輯主語(yǔ)1. 當(dāng)動(dòng)名詞作主語(yǔ)時(shí),其邏輯主語(yǔ)應(yīng)為所有格形式。Toms/His co
