2. The simple past tense denotes an action or state that occurred in a certain time in the past; Habitual, regular actions and behaviors in the past. In English grammar, tense refers to the time when an action takes place, and tene refers to the appearance and state of an action.

Second, the usage is different.

It can be in some sentences that start with here, there, to indicate an action that is taking place.

2. The simple past tense indicates that it happened at a specific time in the past, and it can also indicate a habitual and frequent action in the past. Generally, the impact of the action is not emphasized, only the things that are explained. In general, the past is often used in conjunction with a temporal adverbial or clause indicating the past.

Use the past tense when denoting actions that occurred continuously in the past.

When the subject is not the third person singular, the affirmative sentence is subject + verb form + other, and the negative sentence is subject + don't + verb form + other.

2. There is no third-person singular form in the general past tense, the affirmative sentence form is subject + verb past tense + other, and the negative sentence form is subject + didn't + predicate verb primitive form + other.
