什么是限定动词和非限定动词?
英语上根据动词在句法上是否受到主语的限定,英语动词有可以分为限定动词(Finite Forms of Verbs)和非限定动词(Non-Finite Forms of Verbs).
限定动词又叫谓语动词,在句中充当谓语,在人称和数上必须和主语保持一致,同时还表现出时态、语态和语气的变化.如：
I play basketball.
He plays basketball.
They played basketball yesterday.
The cars are made in China.
非限定动词,又叫非谓语动词,在句中不能单独充当谓语（但可以和情态动词或助动词一起充当谓语）,它们不受主语的限定,没有人称和数的变化,具有名词、形容词和副词的特征,在句中可以充当主语、宾语、表语、定语、状语、补足语等.同时非限定动词也保留了动词的部分特征,有时态和语态的变化,也可以有自己的宾语、表语、状语等,构成非限定动词短语,在逻辑意义上也有其动作的执行者或承受者,叫非限定动词的逻辑主语(Logical Subjects).
