2. The structure of the zero conditional
A conditional is a sentence made up of two clauses. The zero conditional has the following structure:
The order of the two sentences that make up the conditional structure can be changed. If we start with the If condition, we will separate them with a comma. If we start with the sentence that expresses the result, then we won't put a comma.

- The zero conditional is used to express facts which are always true, such as scientific facts or laws, general truths, etc.You get orange if you mix red and yellow.If I eat peanuts, I get ill.
- As well as true facts, the zero conditional can also be used to give instructions. In this case we will use an imperative to express the instruction or warning.If you feel sick, go to the doctor.Don't open the door if someone knocks.
