高考英語(yǔ)第二輪熱點(diǎn)專題復(fù)習(xí)——非謂語(yǔ)動(dòng)詞

1、高考英語(yǔ)第二輪熱點(diǎn)專題復(fù)習(xí)非謂語(yǔ)動(dòng)詞,規(guī)律方法,1考查立意較低，主要考查的是非謂語(yǔ)的一些最基本的用法。但是，題目的設(shè)置注重了情景化和結(jié)構(gòu)復(fù)雜化，加大了考生對(duì)題干句的理解難度。,2設(shè)問的角度呈現(xiàn)出多樣化趨勢(shì)，不僅僅是非謂語(yǔ)間的互相干擾。,命題趨勢(shì)w.w.w.k.s.5.u.c.o.m,不容置疑，高考將繼續(xù)加強(qiáng)對(duì)非謂語(yǔ)動(dòng)詞的考查，試題的特征將繼續(xù)呈現(xiàn)出“情景化”和“設(shè)問角度的多樣化”的趨勢(shì)，但試題的難度將會(huì)有所控制。,突破方法,1非謂語(yǔ)動(dòng)詞的用法是一個(gè)系統(tǒng)性、綜合性很強(qiáng)的語(yǔ)言點(diǎn)，切不可記住幾個(gè)條條框框就去亂套。真正領(lǐng)悟非謂語(yǔ)動(dòng)詞的用法要具備以下基礎(chǔ)知識(shí)：, 具有句子結(jié)構(gòu)的知識(shí)，要分得清簡(jiǎn)單句與復(fù)合

2、句，陳述句與祈使句。, 具有簡(jiǎn)單句最基本的五種句型的知識(shí)，要分得清雙賓語(yǔ)和復(fù)合賓語(yǔ)。, 具有扎實(shí)而豐富的動(dòng)詞知識(shí)，要分得清及物動(dòng)詞和不及物動(dòng)詞，雙賓動(dòng)詞和復(fù)賓動(dòng)詞。一些最基礎(chǔ)最常用的動(dòng)詞的用法應(yīng)當(dāng)爛熟于胸。, 具備各種復(fù)合句的知識(shí)，能夠拆析30詞左右長(zhǎng)度的復(fù)合長(zhǎng)、難句。,2理解分析非謂語(yǔ)動(dòng)詞的句法功能，重點(diǎn)掌握不定式、動(dòng)名詞作賓語(yǔ)的區(qū)別；不定式、分詞作補(bǔ)語(yǔ)的區(qū)別；不定式、分詞作狀語(yǔ)的區(qū)別；獨(dú)立主格的用法；不定式、分詞作定語(yǔ)的區(qū)別。,3解答考查非謂語(yǔ)動(dòng)詞的題目時(shí)，一定要保持頭腦冷靜。一般要遵循以下解題思路：, 解析句子結(jié)構(gòu)，確定設(shè)空在句子中充當(dāng)?shù)墓δ埽ㄈ鐮钫Z(yǔ)、定語(yǔ)或賓補(bǔ)）；, 找準(zhǔn)相關(guān)動(dòng)詞的邏輯

3、主語(yǔ)，確定該動(dòng)詞與邏輯主語(yǔ)是什么關(guān)系（主動(dòng)還是被動(dòng)）；, 搜索句子中相關(guān)的時(shí)間信息，確定非謂語(yǔ)動(dòng)詞的恰當(dāng)形式；, 將該選項(xiàng)置入空中，看是否能夠做到字從意順，或是否能傳達(dá)有效信息、完成交際任務(wù)。,知識(shí)清單,清單一 非謂語(yǔ)動(dòng)詞的句法功能,名稱主語(yǔ)賓語(yǔ)賓語(yǔ)補(bǔ)足語(yǔ)表語(yǔ)定語(yǔ)狀語(yǔ),不定式,動(dòng)名詞,現(xiàn)在分詞,過去分詞,清單二 分詞、不定式作賓補(bǔ)用法要點(diǎn),一、分詞、不定式作賓語(yǔ)補(bǔ)足語(yǔ)的區(qū)別,1感官動(dòng)詞see, watch, observe, look at, hear, listen to, notice 等和使役動(dòng)詞have 后面的賓補(bǔ)有三種形式，即原形動(dòng)詞（不帶to 的不定式）、現(xiàn)在分詞和過去分詞?，F(xiàn)在分

4、詞表主動(dòng)或正在進(jìn)行，過去分詞表被動(dòng)或完成，動(dòng)詞原形表主動(dòng)和完成。如：,I heard her sing an English song just now.,剛才我聽見她唱了一首英文歌。,I heard her singing and English song when I passed by her room yesterday.,昨天經(jīng)過她房間時(shí)，我聽見她在唱英文歌。,I heard the English song sung many times.,我多次聽到有人唱這首英文歌。,注意：不及物動(dòng)詞的過去分詞作賓補(bǔ)表完成和狀態(tài)。如：,I looked down at my neck and f

5、ound my necklace gone. (狀態(tài)),I was surprised to find my hometown changed so much.

8、sth. done 還表示“使遭受”之意。如,Tom had his leg broken while playing football.,Mr. Smith had his house broken into while he was away on holiday., have sb. / sth. doing 使/讓某人/物持續(xù)地做某事（現(xiàn)在分詞表示主動(dòng)，正在進(jìn)行）,get sb. / sth. doing 使某人/物開始行動(dòng)起來,如：The peasants had the tractor working day and night at the harvest time.,農(nóng)忙時(shí)，農(nóng)

13、語(yǔ)補(bǔ)足語(yǔ)。如：,At that time, I found him crying in the street.,He was caught stealing. w.w.w.k.s.5.u.c.o.m,Im sorry to have kept you waiting for such a long time.,The missing boys were last seen playing near the river.,清單三 不定式、分詞作定語(yǔ)用法要點(diǎn),一、不定式作定語(yǔ),1作定語(yǔ)的不定式如果是不及物動(dòng)詞，或者不定式所修飾的名詞或代詞是不定式動(dòng)作的地點(diǎn)、工具等，不定式后面須有相應(yīng)的介詞。如：,

14、The Browns have a comfortable house to live in.,There is nothing to worry about.,Please give me a knife to cut with.,Here is some paper for you to write on.,但是，不定式所修飾的名詞如果是time, place 或way時(shí)，不定式后面的介詞習(xí)慣上省去。如：,He had no money and no place to live (in).,We found a way to solve this problem (in).,2當(dāng)作定語(yǔ)的不

15、定式所修飾的名詞或代詞是不定式動(dòng)作的承受者時(shí)，不定式既可以用主動(dòng)語(yǔ)態(tài)，也可用被動(dòng)語(yǔ)態(tài)，但其含義有所不同。試比較：,Have you anything to send ? 你有什么東西要寄嗎？,（不定式to send 的動(dòng)作執(zhí)行者是“你”）,Have you anything to be sent ? 你有什么要（我或別人）寄的東西嗎？,（不定式to be sent 的動(dòng)作執(zhí)行者是“我”或“別人”）,3用不定式作定語(yǔ)的幾種情況：,不定式表將來：,I borrowed some books to read during my holiday.,用來修飾被序數(shù)詞、最高級(jí)或no, all, any 等

16、限定的中心詞。如：,He was the best man to do the job.,She was the first woman to sin the gold medal in the Olympic Games.,Women and children were the first to get into the lifeboats.,用來修飾的詞是抽象名詞時(shí)，常見的有：ability, chance, idea, fact, excuse, promise, answer, reply, attempt, belief, way, reason, moment, time 等。如：

17、,Do you have the ability to read and write English ?,I have to chance to go sight seeing.,二、分詞作定語(yǔ),1作定語(yǔ)的及物動(dòng)詞分詞形式為：V ing; being + 過去分詞；過去分刻畫 。當(dāng)被修飾的名詞與分詞為主動(dòng)關(guān)系時(shí)，用V ing；當(dāng)被修飾的名詞與分詞為被動(dòng)關(guān)系且表正在進(jìn)行時(shí)，用being + 過去分詞；當(dāng)被修飾的名詞與分詞為被動(dòng)關(guān)系且表完成時(shí)，用過去分詞。例如：,The houses being built are for the teachers.,The broken glass is Tom

18、s.,I have never seen a more moving movie.,2作定語(yǔ)的不及物動(dòng)詞分詞形式為：V ing 和過去分詞。V ing 表示正在進(jìn)行；過去分詞表示已經(jīng)完成。如：,falling leaves 正落的葉子 fallen leaves 落下的葉子,boiling water 正沸騰的水 boiled water 沸騰過的水（白開水）,三、不定式、過去分詞和現(xiàn)在分詞被動(dòng)式作定語(yǔ)的區(qū)別,這三種形式作定語(yǔ)，主要是體現(xiàn)在動(dòng)作的發(fā)生時(shí)間上。過去分詞表示的動(dòng)作或是在謂語(yǔ)所表示的動(dòng)作之前發(fā)生，或是沒有一定的時(shí)間性。如：,Have you read the novel writte

19、n by Dickens ?,He is man loved and respected by all.,Dont use words, expressions, or phrases known only to people with specific knowledge.,現(xiàn)在分詞的被動(dòng)式作定語(yǔ)時(shí)表示的動(dòng)作正在發(fā)生或是與謂語(yǔ)動(dòng)詞所表示的動(dòng)作同時(shí)發(fā)生。如：,Listen !

(修飾全句，獨(dú)立成分),二、分詞作狀語(yǔ),1分詞作狀語(yǔ)形式的選擇,形式意義,V + ing (doing)與句中主語(yǔ)構(gòu)成邏輯上的主謂關(guān)系，與句中謂語(yǔ)動(dòng)詞同時(shí)發(fā)生，或基本上同時(shí)發(fā)生。,having + V + ed,(having done)與句中主語(yǔ)構(gòu)成邏輯上的主謂關(guān)系，先于謂語(yǔ)動(dòng)詞發(fā)生。,V + e

37、d (done)與句中主語(yǔ)構(gòu)成邏輯上的動(dòng)賓關(guān)系。,being + V + ed,(being done)與句中主語(yǔ)構(gòu)成邏輯上的動(dòng)賓關(guān)系，且與謂語(yǔ)動(dòng)詞同時(shí)發(fā)生，一般作原因狀語(yǔ)置于句首。,having been + V +ed,(having been done)與句中主語(yǔ)構(gòu)成邏輯上的動(dòng)賓關(guān)系，且先于謂語(yǔ)動(dòng)詞發(fā)生。,2分詞作狀語(yǔ)的基本原則,分詞作狀語(yǔ)時(shí)，分詞的邏輯主語(yǔ)必須與句子的主語(yǔ)保持一致。,分詞作狀語(yǔ)必須和句中主語(yǔ)含有邏輯上的主謂或動(dòng)賓關(guān)系，否則不能使用分詞作狀語(yǔ)。,3分詞作狀語(yǔ)的句法功能,分詞或分詞短語(yǔ)作狀語(yǔ)時(shí)，可以表時(shí)間、原因、結(jié)果、條件、讓步、行為方式、伴隨狀況等。表示時(shí)間關(guān)系的分詞短語(yǔ)

38、有時(shí)可由連詞while 或when 引出。如：,Hearing the news, they got excited. (時(shí)間),Be careful while / when crossing the street. (時(shí)間),Having been bitten by a snake, she was frightened at it.

40、who, which, when, where, how, what等）+ 不定式，這個(gè)結(jié)構(gòu)在句中起名詞作用，可充當(dāng)主語(yǔ)、表語(yǔ)、賓語(yǔ)。如：高.考.資.源.網(wǎng),I didnt know what to do. (賓語(yǔ)),When to hold the meeting is not known yet. (主語(yǔ)),My question was how to get so many books. (表語(yǔ)),注意句型：Why not do sth. ? Why do sth. ?,二、不定式的主動(dòng)和被動(dòng),1不定式修飾的名詞或代詞和不定式邏輯上構(gòu)成主謂關(guān)系時(shí)，不定式往往用主動(dòng)形式。如：,Do you

41、 have a knife to cut the watermelon ?,(A knife cuts the watermelon.),2不定式和它前面被修飾的名詞或代詞構(gòu)成邏輯上的動(dòng)賓關(guān)系，又和該句主語(yǔ)構(gòu)成邏輯上的主謂關(guān)系時(shí)，不定式常用主動(dòng)形式。如：,She has a sister to look after. (She looks after her sister.),I know what to do. (I do what.),3不定式作表語(yǔ)形容詞的關(guān)語(yǔ)，和句中主語(yǔ)構(gòu)成邏輯上的動(dòng)賓關(guān)系時(shí)，不定式多用主動(dòng)形式，這是因?yàn)槿藗兺J(rèn)為形容詞后省去了for sb. 。如：,This boo

42、k is difficult to understand.,This kind of fish is nice to eat.,4在there be 結(jié)構(gòu)中，當(dāng)說話人考慮的是必須有人去完成某件事時(shí)，不定式用主動(dòng)形式；如果說話人強(qiáng)調(diào)的事情本身必須被完成，則用被動(dòng)形式。如：,There is a lot of work to do. (Someone has to do the work. ),There is a lot of work to be done. (The work has to be done. ),請(qǐng)注意下面兩個(gè)句子的含義的不同點(diǎn)：,There is nothing to do

43、. (無事可做，感到十分乏味。),There is nothing to be done. (某東西壞了，無法使之恢復(fù)正常。),三、不定式符號(hào)to 的保留問題,有時(shí)為了避免重復(fù)，可以用to 來代替前面的不定式，這種情況出現(xiàn)在下列動(dòng)詞之后：expect, hope, wish, mean, prefer, care, forget, want, try；或出現(xiàn)在be glad / happy, would like / love 等的后面。,如果在省略的不定式結(jié)構(gòu)中含有：be, have, have been，這些詞要保留。如：,I havent been to Hong Kong, but I
