1、非謂語動詞一、基本分類非謂語動詞分為三類：分詞（ 現在分詞和過去分詞 ）、動名詞和動詞不定式。它們具有名詞和形容詞的某些特征，因而可以作主語、表語、賓語、定語和狀語。1分詞（1）感官動詞或使役動詞后的現在分詞作補語表示動作正在進行，不定式作補語表示動作發 生的全過程。I saw him walking across the road.（ 正在穿過馬路 ） I saw him walk across the road. （ 看到過了馬 路的全過程 ）及物動詞的過去分詞（do ne）與現在分詞的一般被動式 （bei ng don e）都有被動意義，前者表示 動作完成，后者表示動作正在進行。The

2、picture fixed on the wall was presented by afriend.（ 已經被釘在墻上了 ）The picture being fixed on the wall was presented by a friend.（ 正被釘在墻上 ）注意： 不定式有表將來之意。The picture to be fixed on the wall was presented by a friend.（將要被釘在墻上 ）（3）分詞的獨立主格結構：如果分詞短語的邏輯主語與句子的主語不一致，需用一個獨立結 構（即保留分詞的邏輯主語 ）或者由一個 with / without 引導

3、的介詞短語表達。 Time permitting, we'll do another two exercises.His work finished, he prepared to go home. With his work finished, he prepared to go home.2動名詞（1）動名詞作定語表所修飾詞的用途，而現在分詞表動作或狀態、特征。（2）動名詞的復合結構作賓語，動名詞的邏輯主語可用賓格代詞或不帶所有格。但作主語不 行。Do you mind my / me / Tom smoking here? My / Tom's smoking here

4、annoyed her.（3）動名詞作主語還可用于“ There be no +動名詞”結構和布告形式的省略中。There is no knowing what he will do next.No smoking.3動詞不定式（1）不定式作介詞賓語時，如前面有實義動詞do（各種形式），則不定式不帶to;否則不能省to。He did nothing all the morning but watch TV . He said nothing but to sleep.(2) 不定式作定語時，如果不定式與所修飾的名詞有邏輯上的動賓關系，且不定式的動詞是 不及物動詞，不能漏掉介詞。I want a

5、 small room to live in. I need a nice pen to write with.(3) 不定式作感官動詞和部分使役動詞(let, make)的賓補，動詞不定式不帶to,但句子變成被動語態時，要帶 to。I saw him go into the room. He was seen to go into the room.二、過去分詞過去分詞是非謂語動詞一種重要形式,它在句中可作定語、狀語、表語和賓語補足語。1過去分詞作定語作用相當于一個定語從句。What's the language (that is) spoken in that area? 那個地區

6、講的是什么語言？The book, (which was) written in 1957, tells the struggle of the miners. 這本書寫于 1957年,講 的是關于礦工斗爭的故事。2過去分詞作狀語可以表示原因、時間、條件、方式和伴隨情況。Given advice by the famous detective,the young lady was no longer afraid. 有了著名的偵探的指點 年輕的女士不再害怕了。When heated, water can be changed into steam. 水加熱后可以變成蒸氣。Given more

7、attention, the cabbages could have grown better. 如果多注意一些,這些大白菜還可 以長得更好。The hunter left his house, followed by his dog. 獵人離開了屋子,后面跟著他的狗。He rushed into the room, his face covered with sweat. 他滿臉是汗地沖進屋。三、 動詞不定式1 .省略"to ”的動詞不定式to 是動詞不定式常常帶有的小品詞, 是動詞不定式的標志。 但在下列情況下它常常被省略掉：(1) 作感官動詞 see, watch, hear,

8、 feel, notice 等的賓語補足語時。 We felt the house shake. 我們感到房屋搖晃。 作使役動詞 make, let, have等的賓語補足語時。She lets us meet her at the station.她讓我們去車站接她。(3) help后的賓語補足語前可帶to也可不帶to。She helped her mother (to) prepare for Christmas. 她幫助母親為圣誕節做準備。2. 疑問詞動詞不定式疑問詞 what， which ，how，where，when 等可以和動詞不定式連用，構成不定式短語。 “疑 問詞動詞不定式”

9、可以作主語、賓語、表語等。When to start off hasn't been decided yet. （ 作主語 ） 什么時候出發還沒決定。The question is which bus to take. （ 作表語 ）問題是乘哪輛公共汽車。四、動詞 ing 形式 動詞 ing 形式 （包括現在分詞和動名詞 ）有一般時和完成時兩種 形式，并且也都有被動語態，在句中可以作主語、賓語、狀語和補語等成分。 高考英語試題中對動詞 ing 形式考查主要集中在以下幾個方面：1動詞 ing 形式作賓語在某些 finish, enjoy, appreciate, avoid, sugge

10、st, consider, imagine, stand, excuse, delay, escape, risk, miss,admit, permit, allow 動詞的后面只能接動詞 ing 形式作賓語。My brother is now considering changing his present job. The bird was very lucky because it missed being shot by the hunter.2動詞 ing 形式作賓語時和不定式的區別在 forget, remember, regret 等動詞后接動詞 ing 形式和不定式作賓語在含

11、義上有區別。Remember to put the book on the desk when you leave the room.（ 記得去做某事 ）I remember putting the book on the desk, but it's gone now.（ 記得做過某事 ）3動詞 ing 形式作狀語動詞 ing 形式可以作時間狀語、伴隨狀語、原因狀語等?！?We can't go out in this weather ，” said Bob, looking out of the window.The secretary stayed up late las

12、t night, preparing a report for the manager.4動詞 ing 形式作賓補動詞 ing 形式作補語時和前面的名詞有邏輯上的主謂關系。It is generally considered bad manners to sit with your feet pointing to others.You will be fired if you are found smoking in the kitchen.5動詞 ing 形式的完成時和語態動詞ing形式的被動式由"being + done”構成，它作定語時表示正在進行或和謂語動詞 同時發生的被動

13、的動作；動詞一 ing形式的完成時由"having + done”構成，表示發生在謂 語動詞之前的動作。The stadium being built can hold 50,000 people when completed.Having being shown around the lab, the visitors were taken to the playground. 縱觀近年的高考題，考查點是非謂語動詞作定語、賓語補足語和狀語的區別。一、非謂語動詞作定語時的區別現在分詞 (doing) 作定語，表示一個主動的或正在進行的動作；現在分詞的被動語態(being done)

14、表示一個被動的、 正在進行的動作； 不定式 (to do) 作定語表示一個將要發生的 動作。The meeting (which is) being held now is very important. 正在召開的這個會議很重要。The meeting (which was) held yesterday is very important. 昨天召開的會議很重要。The meeting which will be held tomorrow is very important. 明天將要召開的會議很重要。二、非謂語動詞作賓語補足語的區別不定式與賓語的邏輯關系是主謂關系， 強調動作將發生或已

15、經完成； 現在分詞與賓語 的邏輯關系是主謂關系，強調動作正在進行， 尚未完成； 過去分詞與賓語的邏輯關系是動賓關系， 表示動作已經完成， 多強調狀態。I expect them to win the game. 我期盼他們贏得這場比賽。 I found her listening to the radio. 我 發現她正在聽收音機。I heard him call me several times. 我聽見他給我打了幾次了。三、非謂語動詞作狀語的區別過去分詞表示被動和動作完成；現在分詞表示主動和動作正在進行；不定式表示目的。Discussed (Having been discussed) m

16、any times, the problems were settled at last. 在討論了多次之 后，問題終于解決了。Having finished his work, he went out to play. 完成了工作后，他出去玩了。To catch the first bus, he got up early. 為了趕上早班車，他起得很早。 高考英語非謂語動詞綜合練習1.
