Topic: Tenses
Tenses tell us when an action happens: past, present, or future.
They also show how long something lasts or whether it’s completed.

| Present Continuous | S + am/is/are + verb‑ing |

Tip:
• Use Simple Present for facts, routines, and general truths.
• Use Continuous when the action is in progress at a specific moment.
• Use Perfect to link a past action to another past or present moment.
2. Key Points
| Point | What to Remember |
|---|---|
| Subject–Verb Agreement | Singular subjects take -s/-es in Simple Present (e.g., he runs). |
| Verb Forms | Regular verbs add -ed; irregular verbs have unique past/past‑participle forms. |
| Continuous Forms | Always pair with am/is/are or was/were. |
| Perfect Forms | have/has/had + past participle (e.g., have seen, had gone). |
| Future with “will” | Standard for predictions, promises, or decisions made at the moment of speaking. |
| Conditional Sentences | 1st: real future possibility; 2nd: unreal present/future; 3rd (not listed) for unreal past. |
| Time Expressions | always, usually, often, sometimes, never → Simple Present. |
now, at the moment, currently → Present Continuous. |
|
since, for, already, yet → Perfect tenses. |
|
| Negative and Interrogative Forms | Add not after auxiliary (is not, have not). Questions use auxiliary inversion (Is she?). |
