1、第 8 讲 非谓语动词1. Bats are surprisingly longlived creatures, some _ a life span of around 20 years. (2011浙江卷) A. having B. had C. have D. to have 【答案及解析】1. A考查独立主格结构。句意为“令人惊讶的是,蝙蝠是长寿的动物,有些能活20年左右。”had和have是谓语动词形式,题中没有连词,无法并存两个句子。to have表将来;having表伴随。2. Even the best writers sometimes find themselves _ f
2、or words. (2011浙江卷) A. lose B. lost C. to lose D. having lost【答案及解析】2. B考查非谓语动词。句意为“甚至最优秀的作家有时也会发现他们难以用文字表达自己。”lose是及物动词,A、C、D项都是主动式,空格后没有lose的宾语,故用过去分词lost当形容词用,作find themselves的宾语补足语。3.

3、1浙江卷) A. being cheered B. be cheered C. to be cheered D. were cheered【答案及解析】3. C考查非谓语动词。句意为“如果他们赢了今晚的决赛,队员们将会巡游全城,接受热心支持者的欢呼。”A项being cheered正在进行;B项be cheered是谓语原形;D项were cheered也是谓语,但句中已有谓语are going to;C项to be cheered表示将来,同时也表示被动。4.

4、ly, can improve our health. (2010浙江卷) A. being carried out B. carrying out C. carried out D. to carry out 【答案及解析】4. C考查if条件句的省略。【答案及解析】本句的主语是the experiment,谓语动词是shows, that引导宾语从句,宾语从句的主干是:proper amounts of exercise can improve our health, if _ regularly是插入的条件从句,其完整形式是:if it is carried out regularly,
5、省略了it is。整个句意为:这项实验表明,适当的运动,如果有规律地进行,有利于我们的身体健康。 5. The traffic rule says young children under the age of four and _ less than 40 pounds must be in a child safety seat. (2010浙江卷) A. being weighed B. to weigh C. weighed D. weighing【答案及解析】5. D考查非谓语动词。宾语从句中的主干为:young children must be in a child safety
6、seat。under the age of four and _ less than 40 pounds用于修饰宾语从句主语children。【答案及解析】动词weigh与名词children是主动关系,所以选择weighing。句意:交通法则规定4岁以下并且体重不超过40磅的幼儿必须坐在幼儿安全座上。6. There is a great deal of evidence _ that music activities engage different parts of the brain. (2009浙江卷) A. indicate B. indicating C. to indicate
7、 D. to be indicating【答案及解析】6. B考查非谓语动词。此处是indicating 短语作evidence的后置定语,其中that music activitiesthe brain是动语indicate的宾语从句。动词不定式、分词(现在分词,过去分词)和动名词统称为非谓语动词。现代英语将现在分词和动名词合为一大类叫做v.ing形式。动词不定式、过去分词及v.ing形式在句中均不能作谓语用,所以叫做非谓语动词。非谓语动词形式多样,应用广泛,且在句中起着很活跃的作用,也是语法项目中的重点和难点。动词不定式的要点1动词不定式的形式变化 2.动词不定式的基本用法(1)作主语:T
8、o help each other is good. 动词不定式能起名词、形容词和副词的作用,可在句中作主语、表语、宾语补足语、定语和状语用。(动词不定式作主语时,一般可用it作形式主语,而将作主语的动词不定式置于句末),如:It is good to help each other. (2)作表语:My job is to drive them to the power station every day. (3)作宾语:作及物动词的宾语,如:She wishes to be a musician. 作某些形容词的宾语:这类形容词一般有glad, sorry, afraid, pleased
9、, determined, willing, eager, anxious, ready, sure等,如:I am determined to give up smoking. 当动词不定式之前有疑问词时,就可作介词的宾语,如:Can you give us some advice on what to do next? (4)作宾语补足语,如:Tell the children not to play on the street. 如果句中的谓语动词为see, hear, watch, notice, have, make, let等,作宾语补足语的动词不定式须将to省去,如:I saw
10、a little girl run across the street. (5)作定语:须位于被其修饰的名词或代词之后,如:Is this the best way to help him?(6)作状语:目的状语: Every morning he gets up very early to read English. 结果状语:They lived to see the liberation of their home town. 他们活到亲眼见到了他们家乡的解放。动词ing形式的要点1ing的形式2.ing形式的基本用法(1)作主语:Seeing is believing. 眼见为实。(2
11、)作表语:Her job is washing and cooking. (3)作宾语:作及物动词的宾语。She likes drawing very much.作某些短语动词的宾语。Mary is thinking of going back to New York. do限定词(my, some, any, the等)v.ing,表示“做事”之意,如:do some cleaning打扫卫生do some shopping购物作介词的宾语:Her sister is good at learning physics.作形容词worth, busy等的宾语:This book is well
12、 worth reading. (4)作定语:The sleeping child is only five years old. (5)作宾语补足语:We can see steam rising from the wet clothes. 可以带有这种复合宾语的动词有see, watch, hear, observe, feel, find, have, keep等。 (6)作状语:时间状语:Seeing Tom, I couldnt help thinking of his brother. 分词在句中作时间状语时,其前一般可加when或while,如:When crossing str
13、eet, you must be careful. 原因状语:Being ill, he didnt go to school yesterday. 方式或伴随状语:Mary stood at the school gate waiting for Betty. 过去分词的要点1. 作定语:如果是一个单词,就位于其修饰的名词之前;如果是分词短语,就位于其修饰的名词之后。如:The stolen car was found by the police last week. 2. 作表语:表示其逻辑主语所处的状态,其逻辑主语就是句中的主语,如:The glass is broken. 3. 作宾语
14、补足语:过去分词作宾语补足语时,句中的宾语就是其逻辑主语,如:When I opened the door, I found the ground covered by fallen leaves. 4. 作状语:相当于一个状语从句,该结构的逻辑主语一般都是主句的主语,是过去分词所表示意义的逻辑宾语。为了使作状语的过去分词意义更加明确,常在分词前加when, if, while, though, as等连词,如:Given more time/ If given more time, we could have done it better. (we是该结构的逻辑主语,是give的逻辑宾语。)
15、 易错易混点1疑问词 动词不定式:疑问代词和疑问副词后可加动词不定式构成不定式短语,在句中可作主语、表语或宾语,如: How_to_prevent_them_from_swimming_in_this_river is a problem. 2动词不定式的否定式:由not 动词不定式构成,如: Its wrong of you not_to_attend the meeting. 3v.ing形式与动词不定式在句中作主语、表语、宾语时的区别。 ving形式:表示抽象或泛指的动作。 不定式:表示具体某一次的动作。 She likes playing the piano, but she does
16、nt want to_play it today. 4v.ing形式与动词不定式在句中作定语的区别。ving形式:动作与谓语动词所表示的动作同时发生。 不定式:动作发生在谓语动词所表示的动作之后。 The girl writing_a_letter_there can speak English very well. I have three letters to_write. 5v.ing形式与动词不定式在作宾语补足语时的区别。 (1)不定式作宾补时,其动作一般发生在谓语动词所表示的动作之后,如: I have told them to_come again tomorrow. (2)在se
17、e, watch, hear, feel等之后,如果用v.ing形式作宾补,表示其动作正在进行中,而用不带to的不定式作宾补时,不定式所表示的动作是一个动作的过程,如:I hear her singing in the room. 我听见她正在屋里唱歌。 I hear her sing in the room. 我听见她在屋里唱过歌。6v.ing形式与动词不定式在句中作状语的区别。 ving形式:表示时间、原因、方式或伴随情况。 不定式:作目的或结果状语。 Not_receiving his letter, I wrote to him again. I looked into the win
18、dow to_see what was going on inside. 7v.ing形式与过去分词的区别: (1)语态不同:v.ing形式表示主动概念,及物动词的过去分词表示被动概念。 an inspiring speech鼓舞人心的演说; the inspired audience受鼓舞的听众 (2)时间关系不同:现在分词所表示的动作一般是正在进行中的动作,而过去分词所表示的动作,往往是已经完成的动作,如: the changing world正在变化的世界 the changed world已经变化了的世界8独立主格结构:有时v.ing和过去分词在句中也有自己的独立的主语,这种独立的主语
19、一般为名词或代词,和v.ing还有过去分词构成独立主格结构。该结构在句中一般只作状语。 独立主格中是使用v.ing还是过去分词,则要根据它们的主语和其所表示的动作的主动或被动关系来定,如: The_bell_ringing,_we all stopped talking. . 注意:独立结构中的being或having been常可省去,如: The_meeting_(being)_over,_all left the room. 作伴随状语的独立结构常可用with短语来代替, 如: She read the letter, tears rolling down her cheeks. She read the letter with_tears_rolling_down her cheeks.
