一,二,三,四,五,非謂語動詞是動詞的變體,是為了滿足動詞作除了謂語之外的其他成分而產(chǎn)生的。從該意義上來說,非謂語動詞是動詞的升級版本,彌補了動詞的先天不足。在語法填空和短文改錯題中,這是必考點之一,非常重要。根據(jù)非謂語動詞的類別及功能,該部分涉及的熱點有動詞不定式、現(xiàn)在分詞和過去分詞以及v.-ing等。解決非謂語動詞用法的關(guān)鍵是:一、時態(tài):把握非謂語動詞和謂語動詞的時間關(guān)系;二、語態(tài):把握非謂語動詞和邏輯主語之間的主動或被動關(guān)系;三、句式結(jié)構(gòu):with的復(fù)合結(jié)構(gòu),獨立主格結(jié)構(gòu),獨立結(jié)構(gòu)以及使役動詞的用法等。,一,二,三,四,五,一、非謂語動詞的形式變化,一,二,三,四,五,二、動詞不定式 動詞不定式具有名詞、形容詞和副詞的特征,在句子中可以充當(dāng)除去謂語之外的所有句子成分。 1.不定式作主語 (1)表示具體的某次動作或一件未完成的事或表示目的。如: To lie to your father is wrong.向你父親撒謊是不對的。 (2)it用作形式主語的常見句型: It takes sb.some time to do sth. It is +adj.+for sb.to do sth.(形容詞指某事物的特征、特點) It is +adj.+of sb.to do sth.(形容詞指人的性格、品德)如: Its important for us to keep the water clean. 保持水質(zhì)清潔對我們來說是很重要的。 Its very kind of you to say so. 你這樣說真是太好了。,一,二,三,四,五,2.不定式作表語 (1)表示具體動作,特別是將來的動作或者表示計劃、安排、命令、勸告等。主語常常是表示意向、打算、計劃的詞,如wish,idea,task,purpose,duty,job等。如: My hope is to become a scientist like Einstein. 我的愿望是做一個像愛因斯坦那樣的科學(xué)家。 (2)注意seem,appear的用法。如: They seemed to be eating something when I entered the room. 我進(jìn)入房間時,他們好像在吃東西。 (3)be to blame (責(zé)備),be to let(出租) 常用主動式表示被動。如: You are to blame.你應(yīng)該受到責(zé)備。,一,二,三,四,五,3.不定式作賓語 (1)跟在某些動詞之后,簡單口訣如下: 三個希望兩答應(yīng):hope/wish/want/agree/promise 兩個要求莫拒絕:demand/ask/refuse 設(shè)法學(xué)會做決定:manage/learn/decide 不要假裝在選擇:pretend/choose 如: They managed to escape from the burning building. 他們設(shè)法從著火的大樓逃了出去。,一,二,三,四,五,(2)某些動詞后接“疑問詞+不定式” 常見的有:teach,decide,wonder,show,learn,forget,ask,find out,advise,discuss等。如: I dont know whether to answer the letter. 我不知道是否要回信。 (3)it用作形式賓語來代替不定式的常用句型是:主語+謂語+it(形式賓語)+賓語補足語(形容詞或名詞)+不定式。 常見謂語動詞有:consider,regard,suppose,think,believe,make,feel,find,know等。如: They find it difficult to repay the money. 他們發(fā)現(xiàn)還這筆錢很困難。 We consider it a waste of time and money to go on with the project. 我們認(rèn)為繼續(xù)進(jìn)行這個項目既費時又費錢。,一,二,三,四,五,4.不定式作定語 (1)不定式可用在名詞、代詞、序數(shù)詞、the only和形容詞最高級等后面作定語。不定式作定語常表示將來的動作,而現(xiàn)在分詞作定語表示正在進(jìn)行的或主動的動作,過去分詞作定語表示的則是完成的或被動的動作。常被不定式修飾的名詞有:chance,need,promise,time,opportunity,way等。如: He had no chance to go to school before liberation. 解放前他沒有上學(xué)的機會。 (2)不定式與被修飾的名詞在邏輯上有動賓關(guān)系,如果該不定式是不及物動詞,其后應(yīng)加上必要的介詞。如: She is now looking for a room to live in. 她現(xiàn)在正在找一所房子來居住。,一,二,三,四,五,(3)如果不定式能與主語構(gòu)成邏輯上的主謂關(guān)系,則常用主動式,而不用被動式,否則用被動式。如: Do you have any clothes to be washed?(I will wash them for you.) 你有要洗的衣服嗎? 對比:Do you have any clothes to wash?(You wash the clothes yourself.) 你有衣服要洗嗎? 5.不定式作狀語 (1)不定式作目的狀語往往是高考命題的重點。為了加以強調(diào),有時可把不定式放在句首,或在其前加上in order或so as。用作目的狀語的不定式是一個尚未發(fā)生的將來動作。如: In order to arrive before dark,we started early. 為了在天黑前到達(dá),我們很早就動身了。,一,二,三,四,五,(2)不定式作原因狀語常用在某些表示情感、情緒等的形容詞后面,如happy,kind,surprised,frightened,angry,shocked,glad,delighted,disappointed,sorry等。如: I am so sorry to hear about your failure on business. 聽到關(guān)于你生意失敗的事我很遺憾。 (3)不定式作結(jié)果狀語用于so.as to.,such.as to,enough to.,too.to,only to等結(jié)構(gòu)中(其中only to常表示出乎意料的結(jié)果)。如: He hurried to the booking office only to be told all the tickets had been sold out. 他匆忙去了售票處,結(jié)果被告知所有的票已經(jīng)賣完了。 She was too excited to say a single word. 她太興奮而說不出話來。,一,二,三,四,五,6.不定式作賓語補足語

upon,long for,wait for等。,一,二,三,四,五,(2)接不帶to的不定式作賓語補足語的動詞(短語)有:make,have,let等使役動詞以及see,watch,notice,observe,look at,feel,hear,listen to等感官動詞。如果這些動詞或短語用于被動語態(tài),則to不可省略。動詞help后的不定式符號to可以省略,也可以保留。如: I wont have you say such things. 我可不允許你說這樣的話。 She was seen to enter the managers office ten minutes ago. 十分鐘前有人看見她進(jìn)了經(jīng)理辦公室。 注意:使役動詞leave和get后的賓語補足語用帶to的不定式形式。 (3)用在with/without的復(fù)合結(jié)構(gòu)中,不定式表示將來的動作。如: With many tough problems to settle,the newly-elected president is having a hard time. 有很多棘手的問題要解決,這位新當(dāng)選的總統(tǒng)日子不好過。,一,二,三,四,五,三、v.-ing的用法 v.-ing具有動詞和名詞的特點:動詞的特點體現(xiàn)在可以有自己的賓語、狀語和補足語,有時態(tài)和語態(tài)的變化;名詞的特點體現(xiàn)在可以作主語、賓語、表語和定語。 1.v.-ing作主語 (1)v.-ing作主語可放在句首,謂語動詞用單數(shù),通常用來表示抽象動作或反復(fù)發(fā)生的動作或表示一件已知的事或已有的經(jīng)驗。如: Reading good books makes us happy. 讀好書使我們快樂。,一,二,三,四,五,(2)it用作形式主語的常見句型:It is no good/no use/useless/worthwhile/fun/a waste of time+v.-ing。如: Its no use crying over spilt milk. 覆水難收。 注意:“There is no +v.-ing”表示“不可能,無法做”。如: There is no getting along with him. 簡直無法同他相處。 (3)可以有自己的邏輯主語,當(dāng)作主語時,其邏輯主語常使用名詞所有格或形容詞性物主代詞。如: Toms coming is what we have expected. 湯姆的到來在我們的預(yù)料之中。 His leaving is a great loss. 他的離去是一個巨大的損失。,一,二,三,四,五,2.v.-ing作表語 v.-ing作表語時,句子主語常是表示無生命事物的名詞或what引導(dǎo)的名詞性從句。作表語的v.-ing與主語通常是對等的關(guān)系,表示主語的內(nèi)容,主語、表語可互換位置。如: His favorite sport is swimming.=Swimming is his favorite sport. 他最喜歡的運動是游泳。,一,二,三,四,五,3.v.-ing作賓語 (1)常見后接v.-ing作賓語的動詞(短語)有:consider,suggest/advise,excuse/pardon,admit,delay/put off,fancy,avoid,miss,keep/keep

that train. 我可不敢冒誤了那趟火車的風(fēng)險。,一,二,三,四,五,(2)有些動詞接不定式或v.-ing作賓語皆可,但是意義區(qū)別較大。如: remember to do sth.記住要去做某事 remember doing sth.記得曾做過某事 forget to do sth.忘記要做某事 forget doing sth.忘記做過某事 regret to do sth.很抱歉或遺憾地要去做某事 regret doing sth.后悔做了某事 mean to do sth.打算做,想要去做 mean doing sth.意味著,一,二,三,四,五,(3)作介詞的賓語,也常用于固定短語和句型中。如:be/get used to,devote.to.,look forward to,pay attention to,get down to,think

use等。如: I find it useless advising him to change his mind. 我發(fā)現(xiàn)勸說他改變主意是沒有用的。,一,二,三,四,五,(5)v.-ing和不定式作賓語的轉(zhuǎn)化:want,need,require,deserve等動詞以物作主語時,其后的賓語用主動式表示被動含義或用不定式的被動式。如: Those young trees need watering/to be watered. 那些小樹需要澆水了。 4.v.-ing作定語 只能放在名詞前面,說明該名詞的性能或用途,不用來表示動作。如: Youd better take some sleeping pills before going to bed. 睡覺前你最好服用些安眠藥。,一,二,三,四,五,四、分詞的用法 分詞可分為現(xiàn)在分詞和過去分詞兩種,在句中可作狀語、定語、表語和補語等。 1.分詞作狀語 (1)分詞在句中可作時間、原因、結(jié)果、條件、方式、伴隨狀語,其邏輯主語必須與句子的主語一致。現(xiàn)在分詞表示主動的動作,過去分詞表示被動或完成的動作。其中,分詞作時間、條件、原因、讓步等狀語時,可以和狀語從句替換。如: Having waited in the queue for

(4)分詞在句中作狀語時,其邏輯主語必須與句子的主語一致;如果不一致,必須用獨立主格結(jié)構(gòu)來表示,即在分詞形式前加上它的邏輯主語。如: So many people being absent,we decided to put off the meeting. 這么多人缺席,我們決定將會議延期。,一,二,三,四,五,2.分詞作定語
