- Example: “You should drink more water to stay healthy.”
This sentence implies a suggestion for better health practices.
When should I use “must” instead of “should”?

Model verbs are generally followed by the base form of the main verb, but they can be used with different tenses, particularly when discussing past or future actions.
- Example in future tense with “will”: “I will call you tomorrow.”

In these examples, “will” refers to a future action, and “should have” refers to a past action that was advisable but not done.
What is the role of “would” in polite requests?
“Would” is commonly used to make polite requests or express hypothetical situations. It softens the tone, making the request sound more courteous.
