Answer:
All the tenses in English talk about time.
Explanation:
In the simple present, you talk about daily routines, facts or habits. e.g. Laura plays basketball once a week.
In the present continuous, you talk about activities happening at the moment or future plans. e.g. Kelly is studying for a test now/Kelly is working next week.
In the past simple, you talk about punctual and finished actions in the past. e.g. Juan read a great book last week.
In the present perfect, you talk about actions that started in the past but they have a continuity until the present or indefinite actions. e.g. I have visited Miami three times before.
In the past continuous, you talk about a past action that had a conitnuity for a certain time in the past. e.g. I was washing the dishes last night.
In the future (WILL/GOING TO), you talk about future short-term or long-term plans. e.g. The world will end in 50 years/Ana is going to have breakfast with her mother next Monday.
As you can see, all tenses in English make reference to times in the past, present or future and what you have to do is just to practice them and know how to use them correcly.
