Definition:
Activity refers to verbs. For example, eating, raising, cleaning, etc. are all verbs.
Object refers to the object. In a phrase or sentence, the component following a verb or adjective is called an object, and the object is usually a noun. Such as rice, opinions, etc.
The verb-object structure is the phrase or sentence in which these two components are combined. For example, eating rice, giving opinions, cleaning the classroom, etc.
Extended information:
The verb-object composed of the part of speech of the word after the verb:
1. Nouns, pronouns or noun phrases are generally used as objects . Therefore, if the verb is followed by these words or phrases, it usually forms a verb-object phrase. For example, "eat dinner", "praise them", "learn Lei Feng's spirit", etc. are all verb-object phrases.
2. Quantifiers placed after the verb can be used as objects or complements. Generally speaking, the quantifier composed of object quantifiers is placed after the verb as an object. For example, "come in", "put it in order", "stand at the school gate", etc. are all verb-complementary phrases.
3. The quantifier expressing time is placed after the verb, sometimes as an object, sometimes as a complement. The quantifier indicating time after the verb is moved to the front of the verb as the subject, which makes sense as a verb-object phrase. For example, "li", "pian", and "jin" in phrases such as "run five miles", "read a few articles", "weigh a jin", etc. are all object quantifiers, so these phrases are all verb-object phrases
