First Conditional

IF | Condition | Result |
present simple | WILL + base verb | |
If | it snows | I will not take the bus. |
In the example above we are thinking about something in the future that you will do based on an event. In this case you will use the present simple tense of the verb for the possibility of the condition happening in the future. We then use WILL + the base verb for the future result that we think will happen. With the first conditionals the possibility of the condition happening is very real. Here are some more examples:
IF | Condition | Result |
present simple | WILL + base verb | |
If | you go home tomorrow | Mom will be happy. |
If | he does his homework early | he will have time to play. |
If | you don’t review tonight | you will fail the test. |
If | it snows tomorrow | will you miss work? |
If | it floods tomorrow | where will you go? |
The words shall, can or may can substitute the word will in some cases. For example: If you do your homework early tonight, you may have time to play.
Also, you can switch the order of the clauses(result and condition) along with the if statement:
Result | IF | Condition |
WILL + base verb | present simple | |
Mom will be happy | if | I go home tomorrow. |
He will have time to play | if | he does his homework early. |
You will fail the test | if | you don’t review tomorrow. |
You will miss work | if | it snows tomorrow. |
Where will you go | if | it floods tomorrow? |
