英语中的动词有哪几种形式?
1.从定义上区分:
(1)可以充当句子谓语的动词称为谓语动词。
例如:He wants to go home.他想回家。
主语:He
谓语:wants
宾语:to go home (不定式作宾语,不定式属于4种非谓语动词中的其中一种)
(备注:作谓语动词为wants, 因此为谓语动词)
(备注:不是作谓语而是作宾语的动词to go home,因此为非谓语动词)
(2)不能单独充当句子谓语或者完全不能充当句子谓语动词称为非谓语动词。
例如:She likes watching TV.她喜欢看电视。
主语:She
谓语:likes
宾语:watching TV(动名词作宾语,动名词属于4种非谓语动词中的其中一种)
(备注:作谓语动词为likes, 因此为谓语动词)
(备注:不是作谓语而是作宾语的动词watching TV,因此为非谓语动词)
2.从形式上区分:
(1)如果动词是以:现在分词/过去分词/不定式/动名词形式存在于句子中则为非谓语动词。
