非谓语动词总结知识点一、动词不定式(Infinitive)动词不定式由“to + 动词原形”构成。
动词不定式在句子中可以作多种成分,具有名词的性质。
下面是动词不定式的主要用法:1. 作主语:To travel around the world is my dream.2. 作宾语:I want to study English.3. 作定语:The best way to learn English is to practice speaking.4. 作表语:My goal is to improve my English.5. 作状语:He goes to the library to study every day.当动词不定式作为宾语补足语时,它可以由动词原形构成(Bare Infinitive)。
例如:I saw him draw a picture yesterday. (我昨天看到他画了一幅画。
)二、动名词(Gerund)动名词是由动词的现在分词形式加上动词-ing构成的。
动名词在句子中可以作多种成分,具有名词的性质。
下面是动名词的主要用法:1. 作主语:Reading is my hobby.2. 作宾语:I enjoy swimming in the ocean.3. 作定语:I like watching movies.4. 作表语:His favorite activity is playing basketball.5. 作状语:He left without saying goodbye.动名词与不定式的区别在于,动名词具有名词的性质,而动词不定式具有动词的性质。
