How do you distinguish between the three forms of non predicates? How do you determine when to use w

The form of a non-predicate verb.

1. Verb infinitive: (to) + do, with the characteristics of nouns, adjectives, and adverbs.

2. Gerund: ving, gerund not only has some characteristics of verbs, but also has the syntactic function of nouns.

3. Present participle: -ing form, present participle has some characteristics of verbs, and has the syntactic functions of adjectives and adverbs.

4. Past participle: A regular verb is composed of a verb primitive, ending -ed.

Selection and differentiation of the three forms.

1. The present participle is used to indicate the action that is being carried out now, and the active voice.

2. Past participles indicate actions that have been done or things that have been done, in the passive voice.

3. The infinitive of the verb indicates the action that will take place.

1. Non-predicate verbs are not predicates in sentences. Non-predicate verbs in English are: verb infinitive (to do), present participle (doing), past participle (done), gerund (doing).

2. Verb infinitives, gerunds and participles (including present participles and past participles) can appear in any position in the sentence except the predicate, acting as the subject, object, predicate, definite, adverbial and other components of the sentence, and these verb forms are called non-predicate verbs.

3. General form of verb infinitive: the action represented often occurs after the action of the predicate verb or at the same time as the action indicated by the predicate verb; Verb infinitive progressive: the action indicated is ongoing; Verb infinitive perfect:

The action represented takes place before the action of the predicate verb.

4. The components of a sentence are generally composed of subject, predicate, predicate, object, definite, adverbial, etc. Predicates generally have verbs to serve, and non-predicate verbs cannot serve as predicates independently. But it can serve as other components of the sentence, and here the teacher gives you a brief description as follows:

The infinitive can serve as the subject, object, predicate, object complement, definite, adverbial, etc. Gerunds can act as subjects, predicates, objects, definites, etc. Present and past participles can serve as definite, predicative, object complement, adverbial, etc.

5. For example: He came here to ask for his bikeHe came here to ask for his bike.

Analyze sentence components: he (pronoun) as the subject, came (verb) as the predicate, here (adverb) as the adverb, to ask for his bike (verb inequality phrase) as the purpose adverbial.

For example: hearing the news, he began to cry

Analyze sentence components: hearing the news (non-predicate verb) Now the participle phrase is the adverbial, the he pronoun is the subject, the verb began is the predicate, and the to cry (non-predicate verb) verb inequality is the object.

The common form is a non-predicate split verb, which is a complementary explanation of the predicate. There are three main forms of non-predicate verbs: infinitive, gerund, and participle.

1. Infinitives as expressions:

The infinitive is used to make a predicate to generally indicate a specific action, especially to indicate a future action.

When both the subject and the predicate are infinitives, one denotes the condition and the other denotes the result.

2. Gerunds as predicates:

The gerund is used as a predicate to express an abstract general action.

When a gerund is a predicate, it is the same as the present participle in the progressive tense, but the meaning is different, the participle in the continuous tense indicates that the action is done by the subject, but the gerund is a predicate to explain the nature or situation of the subject.

3. Participle as a predicate:

There are two situations in which a word segment is used as a predicate, one is the present participle as a predicate, and the other is the past participle as a predicate. Verbs that express mental states such as excite, interest, etc. are transitive verbs, and the Chinese meaning of Nalu is not "excited" or "happy", but "to make excited" and "to make happy", so the present participle should be "exciting" and "happy".
