We use conditionals when we want to talk about things that are true now or that may be true in the future. These conditionals usually begin with ‘if’ (less certain) or ‘when’ (more certain). There are different forms of conditional, depending on what you want to say.
Zero Conditional
The simplest is called the zero conditional and we use it to talk about something that is true now or is usually true. We make the zero conditional this way: If/When + PRESENT TENSE, PRESENT TENSE. For example:
If it is warm, I open my windows.
If I am waiting for someone, I look at my watch.
When my alarm goes off, I wake up.
When I am sitting on the sofa, the cat sits on my lap.
First Conditional
We also have the first conditional and it is used for things which may be true in the future, but we are not certain of. We make the first conditional this way: If + PRESENT TENSE, MODAL VERB + INFINITIVE VERB. For example:
If I have time, I will write an email to you.
If I see Bob, I will tell him you are looking for him.
If I drink more coffee, I could get a headache.
