How to identify modal verbs of necessity in a sentence?



Hope you're doing well too! It’s fantastic that Liza is working on modal verbs!
When it comes to choosing between "must" and "have to," here’s a simple way to help her understand the difference:
- "Must" is used when the obligation comes from the speaker's personal opinion or decision. It expresses something that the speaker feels is necessary.
- Example: "You must bring your passport to the interview." (This is something I think is important or necessary.)
- "Have to" is used when the obligation comes from an external source—like rules, laws, or authority figures. It’s a requirement set by someone else, not the speaker.
- Example: "Students have to wear their IDs." (This is a rule imposed by the school, not by the speaker.)
Tips to Remember:
- "Must": Think of it as a personal necessity or strong advice from the speaker.
- "Have to": Use it when talking about rules, regulations, or requirements made by someone else.
She can practice by asking herself: Is this something I think is necessary (must), or is it a rule from someone else (have to)?
Thank you and hope this helps!
