大学英语语法系列讲座--非谓语动词1

非谓语动词讲解(超全)非谓语动词是指动词的非限定形式，不可以独立作谓语。

它可以由动词原形、现在分词和过去分词构成，常见的形式有不定式、动名词和分词。

一、不定式：不定式是动词的一种非限定形式，常常在句中作主语、宾语、表语或定语。

它的构成方式为"to + 动词原形"。

例句：1. To learn a foreign language is not easy.（作主语）2. She wants to go shopping.（作宾语）3. The best way to learn English well is to practice every day.（作表语）4. He has a lot of work to finish.（作定语）不定式也具有进行时态、完成时态和被动语态的形式：进行时态：to be + 动词的现在分词完成时态：to have + 动词的过去分词被动语态：to be + 动词过去分词例句：1. He seems to be sleeping.（不定式进行时态）2. You should have told me earlier.（不定式完成时态）3. The car needs to be repaired.（不定式被动语态）二、动名词：动名词是指动词的-ing形式，它可以作主语、宾语、表语、定语或状语。

在句中的位置和用法与名词相似。

例句：1. Reading is my favorite hobby.（作主语）2. I enjoy swimming in the summer.（作宾语）3. Her dream is becoming a famous singer.（作表语）4. The girl standing over there is my sister.（作定语）5. He went to the party without saying goodbye.（作状语）动名词与不定式的区别在于动名词具有进行时态和被动语态，而不定式没有。

非谓语动词包括动词不定式、动名词和分词。

本文将对这三种非谓语动词进行详细的讲解，帮助读者更好地理解和运用。

专题十 非谓语动词知识摘要非谓语动词包括动词不定式、动名词和分词（现在分词和过去分词）三类，它们没有人称和数的变化，但根据发生的时间、状态及主被动关系有形式上的变化，还可以有自己的宾语和状语。

考点梳理一、非谓语动词的肯定形式二、非谓语动词与逻辑主语构成复合结构形式1. 动名词的复合结构就是在动名词前加上它的逻辑主语。

其形式为：名词所有格/ 形容词性物主代词 + 动名词。

当动名词的复合结构作宾语时，还可用名词的普通格或代词的宾格作逻辑主语。

His not coming to my birthday party made me a little anxious.他没来我的生日聚会使我有点担心。

I remember Jane’s/ Jane going there. 我记得简去过那里。

2. 不定式的复合结构为：for sb./ sth. + 不定式。

It is a must for us to have a good command of English.我们熟练掌握英语是必要的。

3. 非谓语动词的否定式是在非谓语动词前加not 。

I warned him not to come late again.我警告过他不要再迟到。

三、非谓语动词的句法功能考点一、非谓语动词作状语一、不定式、分词作状语的基本原则不定式、分词作状语时，不定式、分词的逻辑主语必须与句子的主语保持一致，即不定式、分词作状语必须和句中主语含有逻辑上的主动或被动关系，否则一般不能使用不定式、分词作状语。

二、不定式作状语1.不定式作目的状语不定式作目的状语的情况较多，如果强调目的性时，不定式前还可加in order 或so as，构成“in order to do”或“so as to do”结构。

“in order to do”结构作目的状语时，可以放在句首也可以放在句中；“so as to do”结构只能放在句中。

“in order to do”和“so as to do”结构置于句中时，不能用逗号隔开。

非谓语动词语法讲解一、非谓语动词的概念动词的基本用法是作谓语。

当句中已经有了谓语动词了，要选或要填的动词就只能用非谓语形式了。

非谓语形式有三种：1、动词不定式：to do 2、动词的ing : doing 3、动词的过去分词：done二、三种形式的含义（基本用法）不定式：表示目的和将来；动词的ing：表示主动和进行；过去分词：表示被动和完成。

三、非谓语动词的时态和语态一般式完成式进行式不定式主动to do to have done to be doing被动to be done to have beendoneing 形式主动doing having done 被动being done having beendone过去分词被动done四、非谓语动词的否定形式在非谓语动词前加not, never. 即 not / never to do, not / never doing五、非谓语动词的复合结构不定式的复合结构：for / of sb. to do sth.动词 ing 形式的复合结构：宾格或所有格+doing (-ing 形式作主语时，用的所有格＋doing)六、非谓语动词的做题步骤1、判定是否用非谓语形式。

方法：看看句子中是否已有了谓语动词了2、找非谓语动词的逻辑主语。

方法：非谓语动词的逻辑主语一般是句子的主语。

3、判断主被动关系。

方法：非谓语动词与其逻辑主语的主动还是被动关系。

4、判断时间关系。

方法：分析句子，看看非谓语动词所表示的动作发生在谓语动作之前、之后还是同时。

之前常用 done; 之后常用to do; 同时常用doing.学习非谓语形式时，建议把三种形式一起来比较学习，会更加有效一些。

七、非谓语动词作主语和表语的比较1、不定式和动名词作主语和表语a. 不定式表示一次性的、具体的动词。

动词ing 常表示一般的、泛指的或习惯性的动作。

如：________ is a good form of exercise for both young and old.A. The walkB. WalkingC. To walkD. Walk(分析) a good form 暗示泛指一般的行为，用动名词作主语，选 Bb. 不定式作主语时，常用it 作形式主语，即用句型：It is + adj. / n. + (for / of sb. ) to do sth.It’s important for us to learn English well.It’s kind of you to help us.注意：下面几个句型是用动名词：It’s no good / use doing sth.It’s usel ess doing sth.There is no need to do sth.2、不定式、动名词、分词作表语的比较1、不定式、动名词作表语，.表示主语的内容。

非谓语动词讲解(超全非谓语动词是指动词的非谓语形式，包括动词不定式、动名词和现在分词。

与主谓结构不同，非谓语动词可在句子中作状语、定语或表语。

在英语中，非谓语动词的形式是相对固定的，但在不同的语法环境中所表示的意义和用法有所差异。

1. 动词不定式（to-infinitive）动词不定式由“to + 动词原形”构成，常常用作动词的宾语、主语、状语或定语。

）- 状语：He went to the store to buy some groceries.（他去商店买了些杂货。

）- 定语：She needs a pen to write her essay.（她需要一支笔来写作文。

）2. 动名词（gerund）动名词是将动词加上-ing构成，常常用作动词的宾语、主语、状语或定语。

例如：- 宾语：I enjoy reading books in my spare time.（我闲暇时喜欢读书。

）- 主语：Swimming is good exercise.（游泳是很好的锻炼。

）- 状语：She left the party early, feeling tired.（她因为感觉累了，所以提前离开了聚会。

）- 定语：The crying baby woke up the whole neighborhood.（哭闹的婴儿把整个邻居都吵醒了。

非谓语动词精讲概述在大学英语四六级考试的词汇和语法部分中，年年必考的一项语法就是非谓语动词(Non-finite Verb)。

非谓语动词分为三类：不定式(infinitive)、动名词(gerund)和分词(participle)。

其特点是：1．不定式、动名词和分词可以做很多句子成分，但就是不能单独做谓语，这也是它们被称为"非谓语动词"的原因。

2．它们具有各种形态：原形、主动态、被动态、进行态和完成态。

3．不定式和动名词可以做主语、宾语、表语、补语等。

但不管起什么作用，它们都具有动词的功能，但无语法上的动词性质，这一点可以通过它们不受主语的人称和数的限制体现出来。

4．分词起形容词和副词作用，可做表语、定语、状语和复合结构中的复合宾语，但不能做主语和宾语。

它也不受主语人称和数的限制。

不定式1．结构不定式的主动态是 to do，其否定式是 not to do，被动态是 to be done，进行态是 to be doing，完成态是 to have done 。

例： 1996 年 6 月四级第 24 题Sir Denis, who is 78, has made it known that much of his collection _ _____to the nation.A) has left B) is to leave C) leaves D) is to be left 结合选项来看，全句的意思： "78 岁的丹尼斯爵士已经向众人宣布他的许多收藏品将留给国家"。

收藏品是"被留给国家"，因此需要一个被动式做宾语，所以答案是 D) is to be left 。

2．不定式做主语例： 1995 年 1 月四级第 55 题It is not unusual for workers in that region _________.A) to be paid more than a month later B) to be paid later than more a monthC) to pay later than a month more D) to pay later more than a monthit 在句中作形式主语。

非谓语动词前言：非谓语动词的用法是一个系统性、综合性很强的一个语言点，不能只记几个条条框框就去乱套，真正领悟非谓语动词的用法需要具备一下基础知识：(1）具有句子结构的基本知识，要分得清简单向与复合句(2）具有简单句最基本的五种句型知识，要分得清双宾语(3）要分得清及物劲词和不及物动词复习内容：简单句的五种基本结构，及物动词和不及物动词，主，表，宾，定，状，补，语。

非谓语动词定义在句子中不是谓语的动词，形式：不定式、动名词和分词（现在分词和过去分词）作用：在句子中充当主语、宾语、状语等。

特点：1.非谓语动词可以有名词作用（如动词不定式和动名词），在句中做主语、宾语、表语。
