How to use the indefinite tense of a verb? How to use the infinitive

The infinitive can only be followed by the verb form.

The verb is infinitive, which is a non-predicate verb. In the grammar of the English Wheel, the infinitive refers to a form of a verb that does not have a conjugation and does not indicate the person, quantity, or tense. It is called an infinitive because the verb is not limited, or rather not limited by the part of speech.

The infinitive belongs to the non-predicate verb form.

However, in some languages (e.g. Portuguese), there are infinitive forms that are influenced by tense, person, and quantity. There are also languages that have no infinitives at all, such as Arabic, Bulgarian, and Modern Greek.

In English language courses, the infinitive form is called "dictionary word" because it is generally used as the prefix of the verb in the dictionary.

The infinitive can be used as any sentence component of the sentence except the predicate in the sentence, but it is a verb after all, so it has the attribute of a verb.

The infinitive and its phrase can also have its own object, adverbial, although the infinitive does not have a direct subject on the surface grammatically, but the meaning it expresses is an action, and this action must be made by the mover (the user of the verb). This mover (the user of the verb) we call the logical subject.

Usage of the infinitive Infinitive The infinitive has various functions in a sentence and can generally be classified into three basic usages: as a noun, as an adjective, and as an adverb. (1) The usage of the infinitive as a noun The infinitive plays the role of a noun and acts as the subject, predicate, object and object complement in the sentence.

As the subject The noun usage is the same as the noun and can be used as the subject of the sentence.

2.As a predicate Infinitive, like a noun, can be deprecated to be placed after the verb be to form a predicate.

3.The infinitive as an object is used after the transitive verb. Commonly used transitive verbs are:

want, wish, hope, like, begin, start, help, agree, refuse, promise, learn, forget, know, need, try, etc.

4.Be an object complement.

It depends on the language.

In English, the infinitive is a variation of a verb.

Verbs are predicates in sentences. However, when the verb has other components, the verb conjugation is used, i.e., the non-predicate verb.

Non-predicate verbs are divided into three categories: doing, done, to do

This third type is the infinitive you are asking.

1 When a verb is the subject of a sentence, the infinitive can be used: to study grammar is difficult for meHere the verb "learn grammar" is the subject, so the infinitive is used.

2 In the same way, it is also possible to be an object. The common ones are want to do or need to do (in this case, need is a real verb, not a modal verb) and so on, not so much a fixed collocation. It's better to analyze scientifically, in fact, the infinitive is the object of words like want or need!

3 Affirmatives, yes, there is wood? When to do is used as a definite, it is postpositioned, that is, it is placed after the modified word. ).
