一、动词不定式的语法功能不定式属于非谓语形式,它不随主语的人称、数和时态变化而变化。其基本形式为to+动词原形,有时可以不带to,在句中不能作谓语,但可以作句子的主语、表语、宾语、定语、状语和宾语补语。动词不定式仍保留动词的很多特征,可带有自己的宾语、状语、逻辑主语等。 1. The grammatical function infinitive form of the verb infinitive is a non-predicate form that does not change with the subject’s person, number, and tense. Its basic form is the to + verb prototype. Sometimes it can be used without to, and can not be used as a predicate in a sentence, but can be used as the subject, expression, object, attributive, adverbial, and object complement of a sentence. Verb infinitives still retain many characteristics of verbs, with their own objects, adverbials, logical subjects, and so on.
