动词不定式、V-ing形式、过去分词是中学英语中比较难掌握并且在应用中难于区分的几种常用词汇形式。它们不但发生了词形变化、词类转化,而且还存在着同形异义、同义不同形等方面的应用难题;再者,由于这三者都是不受主语限制的,统称为非限定性动词,可以作主语、表语、宾语、宾语补足语、定语、状语等,因此,我们对这三种动词形式的作用进行比较具有非常重要的意义。 Verb infinitives, V-ing forms, and past participles are commonly used vocabulary forms that are harder to master in middle school English and difficult to distinguish in applications. Not only have they changed their form and part of speech, but they also have applied problems such as homomorphism, synonymy, etc. Moreover, since all three are not restricted by the subject, they are collectively called non-limitative verbs. Can be used as subject, predicative, object, object complement, attributive, adverbial, etc. Therefore, we have a very important significance in the comparison of the effects of these three forms of verbs.
