非谓语动词讲解和练习(附答案)

非谓语动词讲解和练习(附答案)

非谓语动词非谓语动词是英语语法中的一个重要概念,指的是在句子中不能单独作谓语,但又具有动词特征的动词形式。

一、种类非谓语动词主要包括三种形式:不定式(Infinitive)、动名词(Gerund)和分词(Participle)。

1.不定式基本形式是“to + 动词原形”(有时可省略to),例如“to study”、“to play”等。

它具有名词、形容词和副词的特征,可在句中充当主语、宾语、表语、定语、状语和补足语等成分。

To see is to believe.(作主语和表语)I want to learn English.(作宾语)2.动名词形式上是动词原形加-ing,和现在分词的形式一样,如“swimming”、“reading”等。

动名词在句中主要起名词的作用,可充当主语、宾语、表语和定语。

Swimming is my favorite sport.(作主语)I enjoy reading books.(作宾语)3.分词现在分词:也是动词原形加-ing,它既有动词特征,又有形容词和副词特征,可作定语、状语、表语和补足语。

The running boy is my brother.(作定语)Hearing the news, she couldn’t help crying.(作状语)过去分词:通常是动词原形加-ed(规则变化)或有其特殊的不规则变化形式,如“broken”、“written”等。

过去分词常表示被动或完成的意义,同样能充当定语、状语、表语和补足语等成分。

The broken cup is on the table.(作定语)Given more time, I can do it better.(作状语)二、用法区别1.作主语时不定式作主语常表示具体的某一次动作或行为,常用“It + be + 形容词+ (for/of sb.) + to do sth.”这样的结构,It is important for us to learn English well.动名词作主语往往表示抽象的、一般性的行为或概念。
