📘 Phases Rules & Uses

1. What are Phases?

Phases describe the stage or time of an action. Understanding phases helps in identifying **tense, progression, or completion** of a verb.

2. Types of Phases

• Simple Phase: The action is general or habitual. Example: “He eats breakfast.”
• Progressive Phase: The action is ongoing. Example: “He is eating breakfast.”
• Perfect Phase: The action is completed. Example: “He has eaten breakfast.”
• Perfect Progressive Phase: The action is ongoing but started in the past and continues. Example: “He has been eating breakfast for 10 minutes.”

3. Rules for Phases

• Use **helping verbs** correctly: is/are/was/were, has/have/had, will/shall.
• Progressive phase always uses the **-ing form** of main verb.
• Perfect phase uses **past participle** with has/have/had.
• Perfect progressive phase combines **has/have/had + been + verb-ing**.
• Always check **subject-verb agreement** in all phases.
• Use time markers: for, since, already, just, etc. for clarity in perfect and perfect progressive.

4. Examples for Practice

• Simple: “She walks to school.”
• Progressive: “She is walking to school.”
• Perfect: “She has walked to school.”
• Perfect Progressive: “She has been walking to school for 20 minutes.”
