1. Overview:
The First Conditional is a way to talk about real and possible situations in the future. We use it when we think something might happen if a certain condition is met.
Structure:
If + present simple, will + base form of the verb
2. Cases of Usage:
Case 1: To express a possible future action or event.
Example: If it rains, I will stay home.
Case 2: To make promises or offers.
Example: If you help me, I will buy you lunch.
Case 3: To give warnings or advice.
Example: If you don't study, you will fail the test.
3. Exceptions or Things to Pay Attention To:
The First Conditional is used only for real and possible situations. It does not work for things that are impossible or very unlikely.
4. Additional Notes:
Remember to use "if" with a present simple verb in the condition part (e.g., "If it rains") and "will" with a base verb in the result part (e.g., "I will stay"). Common mistakes include mixing tenses or using "would" instead of "will" in the result part.
