What are the verb tenses? What do they all mean?

In English, actions or states that occur at different times and in ways are represented by different forms of predicate verbs, and the verb forms that indicate when and how actions or states occur are called verb tenses. Verbs are words used to describe or express various actions. Basically, every complete sentence has a verb, and when it comes to representing the second action, it can be connected by indefinite words, gerunds, equivalent conjunctions, subordinate conjunctions, or adding clauses.

In English, verbs are divided into various tenses according to time and type of action. Tense is made up of "tense" and "tense". "Tense" has 4 main parts, namely present, past, future, and past-future; There are also 4 types of "states", namely, general, progressive, complete, and complete.

Combining the 4 "hours" and the 4 "tenses" together is the type of tense, and there are 16 types of tenses. In middle and high school, it is generally not necessary to master the six tenses of raising in the lower right corner.

1. Definition of tense:

In EnglishActions or states that occur at different times and in different ways are usedDifferent forms of predicate verbsThis form of the verb that indicates when and how the action or state takes place is calledVerb tense

In English, actions are discussed in two aspects: one is "time", which means the time when the action occurs; The other is "state", which is used to indicate the extent to which the action has been carried out. This is known as the "tense".

"Posture" is further divided into four degrees of action: general action, performing action, completing action, and completing progressive action.

2. As can be seen from the above, the full name of "tense" is "verb tense", so it must depend on "the form of the predicate verb". Therefore, when speaking of tense, verbs cannot be missing.

3. Time can see when the action occurred, but it can't see whether the action is completed.

For example: he finished homework yesterdayHe finished his homework yesterday. (I did it yesterday in the past.) ）

he had worked yesterday.He finished his homework by yesterday. (I did it yesterday before this point in time.) ）

Conclusion: Time alone is not enough, time can indicate the state of the action, but it cannot determine the state of the action. The time and state of the action are determined by the form of the predicate verb, and time can play the role of a hint.

4.There are 5 basic sentence patterns for simple sentences in English:

1) Subject + predicate.

things change.Things are changing.

2) Subject + conjunctive verb + predicate.

mr. turner is an artist.Mr. Turner is a painter.

3) Subject + Predicate + Object.

we never beat children.We never hit our children.

4) Subject + predicate + (indirect) object + (direct) object.

i'll write you a long letter.I will write you a long letter.

5) Subject + Predicate + Object + Complement.

i found the book easy.I found this book not difficult. (adjective easy as a complement).

i'll let him go.I'm going to let him go. (The infinitive go is used as a complement).

Because in mind, verbs can be reflected. The time when the action takes place, so. Tense. changes. It is reflected by the verb. The structure of the verb determines the tense. form.
