7、同时发生，或者发生在它的后面；I heard her sing. (唱和听见同时发生)I expect to come back next Sunday.(“回来”发生在“预计”之后)2. 不定式完成式：表示的动作发生在谓语动词表示的动作之前；He pretended to have reviewed his lessons.I am glad to have met you before.3. 不定式进行式：表示的动作与谓语动词表示的动作同时发生；She seems to be waiting for somebody.When he came to see me, I happened t

8、o be taking a bath.4. 不定式完成进行式：表示的动作发生在谓语动词表示的动作之前，并延续到那个时候，可能仍在进行；She is said to have been waiting a novel this year.She seemed to have been working on a difficult maths problem.5. 主动语态：一般表示主动的意义，但有时也可以表示被动意义；They began to learn Japanese last winter.Some stars are too far to see.(= to be seen)6. 被动

9、语态：表示被动的意义；The composition contest is to be held next month.She is anxious to be invited to the ball.二、 不定式的句法功能：1. 作主语：一般表示具体的某次动作。1)不定式作主语时，谓语用单数： To do such things is foolish. 2)主系表结构： To see is to believe.3)当主语较长，谓语较短时，常用it做形式主语，将不定式放到谓语的后面。 常用于下列结构中：(1)It is/was +adj.+(of sb.) to do（如 good/ kin

10、d/ nice/ clever/ foolish/ selfish）(2)It is +adj.+(for sb.)+to do（如easy / difficult / hard / / unwise / possible/ necessary）(3)It is +a/an +名词+ to do.（如a pity/ a shame / a pleasure /ones duty / an honor ） (4)It takes (sb.) some time / courage / patience to do(5)It requires courage / patience / hard w

11、ork to do2. 作表语：常表示将来的动作或状态。Her wish is to become a lawyer.3. 作宾语：ask, agree, care, choose, demand, decide, expect, fail, help, hope, learn, manage, offer, plan, prepare, pretend, promise, refuse, want, wish等只能用动词不定式作宾语。注意:1.某些及物动词可用-ing也可用动词不定式作宾语但意义不同stop/ go on/ remember/ forget/ regret/ try/ mea

12、n.2.某些及物动词think, believe, consider, feel, find, make等后常用it作形式宾语。 4作定语：当不定式的逻辑主语是句子的主语时，要用主动表被动。Xiao Li is a very nice person to work with.He wants you to be his assistant. The pen is very nice to write.(用主动表被动)5. 作状语：表示目的、结果、原因和情况，不定式的逻辑主语通常是全句的主语；To make a living, he had to work from morning to til

13、l night. (目的)6. 作宾语补足语：宾语是不定式的逻辑主语，不定式在表示知觉的动词和使役动词后，不用to ，在动词help后to可用可不用。这些动词有see, hear, feel, watch, notice; have, make, let等。但如果句子是被动语态，则to不可省略。He asked me to help him.She usually helped her mother (to) wash clothes on Sundays.7. 同位语: Is this your purpose, to avoid being punished?8. 独立成分: To tel

14、l you the truth, I dont like you. 类似的有：to be frank坦率地说，to cut a long story short 长话短说，等等。三、 不定式的其他用法1. “疑问词+不定式”结构，不定式可以和who, whom, whose, what, which, when, how, where, whether等连用，构成动词不定式短语，在句子中起名词作用，可作主语，宾语，表语等成分。Where to go has not been decided.(主语)We dont know what to do next.（宾语）2. “形容词+不定式”结构，

15、部分形容词可后接不定式，与句子主语在逻辑上构成主谓关系，这类形容词多是表示思想感情的，如，eager, sure, glad, lucky等。I am glad to hear the news.She is sorry to have missed the show. 3. 不定式的省略：1）表示感觉的动词（see, watch, listen to, look at等 ）后作宾语补足语时，to可省略；2）使役动词make, let, have后；3）help后可省，可保留，被动语态要保留to; 4）两个不定式并列时，保留第一个，其余省略；5）had better, would rather

16、 than, cannot but, do nothing but等后可省略to.当堂导练一：用括号中动词不定式的适当形式填空。1. Its an honour for me _(ask) to deliver a speech at the meeting.2. We found them _ (work) hard all the time.3.

21、去分词一般式fallen三 分词的句法功能1） 作表语：相当于形容词，表示性质或状态（不同于进行时和被动语态中的分词，其中的分词是谓语的一部分，表示具体的动作）The invention is encouraging.(The machine is working.)She is unmarried.(The window was broken.)2) 作定语：单个分词通常作前置定语，有时也可放在后面；分词短语作后置定语，其作用相当于定语从句She told us an exciting story.His spoken English is very good.These are the c

22、olor TV sets made in Shanghai.3) 作状语：表示时间、原因，条件、结果、伴随情况与方式等，有时分词前可用when, while等连词，分词作状语的逻辑主语必须和主句的主语保持一致。Hearing the news, she jumped with joy.(时间)While working in the countryside, we learned a lot from the peasants.（时间）Not knowing how to get there, he had to go by taxi.（原因）If working without playin

29、词构成特征具有名词的特征，也具有动词的某些特征，可以带宾语或由状语修饰，动名词和宾语或状语一起构成动名词短语二、 动名词的形式时态语态动词性质及物动词不及物动词主动语态被动语态主动语态一般式praisingbeing praisedcoming完成式having praisedhaving been praisedhaving come三、 动名词的句法作用1. 作主语：为保持句子平衡，可用it作形式主语，而将动名词短语放在句末，其逻辑主语泛指人们。Working all day made her tired.Its no use crying over spilt milk.2. 作宾语：可

30、作及物动词的宾语、作介词宾语、作形容词worth和busy的宾语，有时可用it作形式宾语(think，find，consider等)，其逻辑主语一般特指，有时也可泛指。Would you mind my smoking here?I am looking forward to hearing from my father.The teacher considers it no good reading without understanding.3. 作表语：不要和进行时混淆，进行时说明谓语动作是由主语完成的，但动名词只是说明主语的内容，往往是无生命的名词或由what引导的名词性从句。My j

31、ob is teaching English.He is driving a car.(现在进行时)His job is driving a car.(动名词)4. 作定语：动名词作定语起修饰作用，用于说明名词的用途和目的，且只能放于所修饰词的前面。It is important to use a good learning method.(a method of learning)The man sitting at the working desk(a desk for writing) is a young writer.四、 动名词与现在分词的区别1. 作定语时：动名词作定语修饰主语，

32、用以说明主语的性质、用途及目的，与主语之间没有逻辑上的主谓关系；而现在分词作定语，表示主语的动作或状态，两者之间存在逻辑上的主谓关系。This is a dancing hall.(动名词)China is a developing socialist country.(现在分词)2. 作表语时：动名词作表语，具有名词性质，说明主语的内容或情况；分词作表语，相当于形容词，表示性质和状态。His hobby is fishing.(动名词)His speech was inspiring.(现在分词)After class：Step5: 自辅落实I.改正下列句中的错误。1.

38、izing考查动名词作主语。所填词表示主动关系和一般概念，故填动名词的一般主动式。2.the考查冠词。上文已出现过a text，故此处表示特指，所以用定冠词the。3.it考查代词。此处用it代替前面的the whole text。4.what考查宾语从句。working out后的从句是宾语从句，从句中缺少主语，所填词表示“什么”，故填what。5.are told考查时态和语态。tell与you为动宾关系，所以要用被动语态，且文章的时态基调是一般现在时，故填are told。6.which/that考查定语从句。空处所填词引导限制性定语从句并在从句中作主语，先行词是information，故用which/that。7.like考查介词。此处是在举例，故用like(像)。8.more考查比较级。由后面的than可知，此处要用many的比较级形式，故填more。9.definitely考查副词。修饰谓语动词应该用副词，故填definitely。10.if考查条件状语从句。if表示“如果”，在此引导条件状语从句。Step6:课后反思【精品文档】第 8 页
