First Conditional Sentences

First conditional sentences are used to talk about possible future situations and their likely outcomes. In these sentences, the condition is something that might happen in the future, and the result is something that will happen if the condition is met.

Structure of First Conditional Sentences: The structure of a first conditional sentence is:

If + present tense, will + base verb.

Example Sentences:

If it rains, we will stay home.
If you study, you will pass the test.
If they call, I will answer the phone.

Rules and Usage of First Conditional Sentences

1. Present tense is used in the condition (after “if”), and future tense is used in the result (main clause). This shows that the result depends on the condition being met in the future.

Example:

If you work hard, you will succeed.

2. First conditional sentences are used for possible situations that may happen in the future and their likely results.

Example:

If she applies, she will get the job.

3. The condition is in the present tense because we are talking about something that might happen in the future, and the result is in the future tense because it’s what will happen if the condition is met.

Example:

If I have time, I will help you.

4. The word “if” can be replaced with “when” if we are sure the condition will happen, but in the first conditional, “if” is more common because we’re talking about possible conditions.

Example:

If the train comes on time, we will reach the city by 7 PM.

Usage of First Conditional Sentences

First conditional sentences are used to talk about real and possible situations in the future. They are very useful for expressing predictions, warnings, offers, and promises. We use them when we believe the condition has a chance of happening, and if it does, the result is certain to happen.

Examples of Usage:

Prediction:

If it rains tomorrow, we will cancel the picnic.

Warning:

If you don’t study, you will fail the exam.

Offer:

If you need help, I will give you a hand.

Promise:

If I finish my work early, I will call you.
