Non-predicate verbs, also known as non-predicate verbs, refer to verbs that are not predicates in sentences, mainly including infinitives, gerunds and participles (present participles and past participles), that is, the non-predicate forms of verbs. Non-predicate verbs can not only act as predicates independently, but also carry other components of the sentence.

Three forms of non-predicate:
Now participle/gerund: -ing
Past participle: -ed
Infinitive-do
Therefore, how to distinguish predicate verbs can start from the following two points:
1, verbs other than the above three distinct non-predicate verbs are predicate verbs;
2. If there is a difference between the past and the future (tense can be said), or a modal verb opens the way, or a prototype (except for the special verb-object complement structure), it must be a predicate verb.
However, the -ed form of verbs can be either past tense or past participle. Discrimination: very simple, the rules are as follows: if it is an intransitive verb, the ed form is the predicate; If it is a transitive verb, the ed form with an object is a predicate, and the one without an object is a non-predicate.
