Use the verb type tense to form affirmative sentences

The gerund is a pure short-term definite that only expresses a nature or state, and has nothing to do with the tense. For example: a waiking stick, a crutch, where wa king means to assist in walking, there is no question of any wild tense.

Methods of changing declarative sentences into negative sentences:

There are verbs in sentences like be ( am , is , are , was , were), modal verbs (can could , may , must , will , would , etc.), auxiliary verbs (such as has had in the perfect tense), and add not directly after these words when changing negative sentences; Otherwise, the auxiliary verb do should be added, does (the third person singular of the subject), did (simple past tense), and the original verb should be restored; Such as he goes to school-he doesn't go to school.

In addition, some in the sentence is generally changed to any, if there is and should be changed to or, (because the juxtaposition in the negative sentence should be changed to or) already changed to yet (and placed at the end of the sentence); The negative sentence of the imperative sentence is to add don't directly at the beginning of the sentence; Such as open the doo r, please .-don’t open the door ,please .The negative sentence of the infinitive is to add not before the infinitive, as in she asks the boy not to play in the street

Have a happy holiday season and make progress in your studies! If you don't understand this question, please ask again;

Add do not in front of the verb, and if the verb is a be verb, add not directly

i like you---i do not like you

this is a car---this is not a car

Well, what is a predicate is generally the original form of the verb or the verb with a modal verb, which can be used as a predicate for non-predicate words that are infinitive gerunds, this line.

Only verbs have tense conjugations in English.

In English, German, French, and Russian, only verbs have tense changes, while in Japanese and Korean Chinese, verbs, adjectives, and adjectives have tense changes.

Tense is a grammatical category that is a form of verb (including adjectives and adjectives in Japanese and Chinese) used to indicate various ways of time and occurrence.

Time has four main parts, namely the present, past, future, and past future. There are also four kinds, namely, General, Complete, Performed, and Completed Progressive. Combining these temporal and action aspects constitutes 16 tenses.

Each of the four methods has its own characteristics, which are described as follows:

1) General way.

To narrate a simple fact, the time can be unspecific.

The general aspect of a dynamic verb often indicates that the action is completed.

2) How it is done.

It is used to indicate that an action has been completed.

Spanning two times. The action takes place at the previous time, but the speaker's interest is generally at the later time.

3) How to proceed.

It means that the action is carried out in a period of time, and the speaker's interest is generally not in when the action begins and when it ends, but in the time he is concerned about.

It often presents a kind of scene, so it is highly descriptive and vivid.

4) Complete the way it is carried out.

It has the characteristics of both completion and progress.

It also spans two times, but the two are often not far apart, indicating that the action has continued from the past to the present.
