First Conditional
The first conditional structure isn’t rigid because it can vary depending on the sentence. The “if” clause can appear or not in the beginning of the sentence.
If + subject+ Simple Present verb, +subject+ will+ verb+ complement
For example:
If the phone rings, I won't answer it.
If he gets up at 5 o’clock, he will eat breakfast
Or:
Subject+Will+verb+ IF+ present simple+ complement
For example:
I’ll give you ten dollars if you eat lettuce.
My boss will get angry if I arrive late.
