Past, present and future
Does it happen before now, now, or later?
Znaczenie
A speaker can place an event or state before now, in the present, or later. This helps the listener separate earlier events, current situations, and future events. Many languages use tense, a choice of verb form that marks time. Other languages, such as Mandarin, have no tense forms and use time words and context. When and how long gives a more precise time or duration; How an event unfolds tells us whether an event is in progress, complete, repeated, or connected to another time.

Ask whether the event or state belongs before now, in the present, or later. Look for verb forms, helper words, time expressions, or context that give you that answer.
W języku nauki
English has present tense and past tense verb forms; the past is often marked by -ed, but many common verbs use a different form. A present tense form can describe habits and states, while present tense be plus an -ing form often describes an action happening now. Future time is commonly expressed with will, be going to, or a present tense form supported by context.
We walked home yesterday.
The ending marks past tense.
Lena works at a cafe.
A present tense form describes a regular activity; with he, she or it, it ends in -s.
Maya is cooking right now.
A present form of be with an -ing verb form describes an action in progress now.
I will call you tonight.
Our train leaves at six tomorrow.
A present tense form describes a scheduled future event.
Learners whose language leaves verbs unchanged for time may keep a present form in a past sentence, as in *Yesterday we walk home. Learners whose language uses one main future form may overuse will where a present form is usual, such as in a timetable.
