如何判断非谓语动词讲解非谓语动词是指在句子中具有动词性质,但不作谓语的动词形式。

常见的非谓语动词形式包括:不定式、现在分词、过去分词。
2. 句法功能:非谓语动词可以作为主语、宾语、定语、表语或状语等句子成分。
根据其在句子中的作用,我们可以判断非谓语动词的句法功能。
3. 语义特征:非谓语动词往往具有较强的动作性或状态性。
根据上下文的语义,我们可以推测非谓语动词所表达的动作或状态的特点。

非谓语动词的句法功能及比较一、作主语(现在分词和过去分词不能作主语)1.不定式与动名词作主语,在表示抽象概念时两者往往可以互换。

It is necessary to read it many times.To finish the task within two weeks is very difficult.◆主语是不定式,表语一般也要用不定式,动名词的情况也是如此。
To see is to believe. Seeing is believing.2.在下列结构中常用动名词(往往表示比较抽象的动作)It is no use doing sth.It is no good doing sth.It is (a) waste of time/money doing sth.There + be + no + doinghave trouble/problem/difficulty (in) doingspend time/money (in) doinghave a good/hard time in doing sth.have fun in doing sth.There is no joking about such matters.There is no denying the fact that the new method is much better.二、作宾语(现在分词和过去分词不能作宾语)1.英语中有个别动词后面带不定式和动名词作宾语意义上无很大的区别。

动词的非谓语形式一非谓语动词的句法功能二分词、不定式作宾补用法要点一、分词、不定式作宾语补足语的区别1.感官动词see, watch, observe, look at, hear, listen to, notice 等和使役动词have 后面的宾补有三种形式,即原形动词(不带to 的不定式)、现在分词和过去分词。
现在分词表主动或正在进行,过去分词表被动或完成,动词原形表主动和完成。
如:I heard her sing an English song just now.刚才我听见她唱了一首英文歌。
I heard her singing and English song when I passed by her room yesterday.昨天经过她房间时,我听见她在唱英文歌。
I heard the English song sung many times.我多次听到有人唱这首英文歌。
注意:不及物动词的过去分词作宾补表完成和状态。
如:I looked down at my neck and found my necklace gone. (状态)I was surprised to find my hometown changed so much. (完成)2.leave 后接三种形式作宾补时,其中的leave 保留了原来之义―留下‖,但表达的确切之义应是―使……处于某种状态)。
leave sb. doing sth. 让某人一直做某事(宾语和宾补之间是主谓关系,表示动作正在进行。
)leave sth. undone 留下某事未做(宾语和宾补之间是动宾关系,表示被动和完成,一般以undone, unfinished, unsettled, untouched 为多)leave sb. to do sth. 留下某人做某事leave sth. to be done 留下某事要做(不定式表示将来的动作。
在句子中充当除谓语以外的各种句子成分的动词形式叫做非谓语动词(the Non-Finite Verbs)。
非谓语动词有三种:不定式(the Infinites)、动名词(the Gerunds)和分词(the Participles)。
动词不定式的时态、语态动词不定式可以作以上各种成分,但它毕竟是动词,所以有动词的属性动词不定式及其短语还可以有自己的宾语、状语,虽然动词不定式在语法上没有表面上的直接主语,但它表达的意义是动作,这一动作一定由使动者发出。
这一使动者我们称之为逻辑主语,其形式如下:主动形式被动形式一般式(not)to make (not)to be made完成式(not)to have made (not)to have been made进行式(not)to be making完成进行式(not)to have been making(1)语态如果动词不定式的逻辑主语是这个不定式所表示的动作的承受者,不定式一般要用被动语态形式。
如:It's a great honour to be invited to Mary's birthday party.(不定式作主语)It was impossible for lost time to be made up.(不定式作主语)I wish to be sent to work in the country.(不定式作宾语)Can you tell me which is the car to be repaired?(不定式作定语)He went to the hospital to be examined.(不定式作状语)在There be结构中,修饰主语的不定式可用被动,也可用主动。
如:There are still many things to take care of (to be taken care of).但有时两种形式表达的意思不同,如:These is nothing to do now.( We have nothing to do now.) There is nothing to be done now.(We can donothing now.)(2)时态1) 现在时:一般现在时表示的动词,有时与谓语动词表示的动作同时发生,有时发生在谓语动词的动作之后。
