Zero Conditional Exercise

Zero and first conditionals are types of conditional sentences used to describe actions or events that are dependent on a certain condition being met.

The zero conditional is formed by using the present simple tense in both the `if` clause and the main clause. For example, `If it rains, the ground gets wet.`

The first conditional is formed by using the present simple tense in the `if` clause and the future simple tense (using `will`) in the main clause. For example, `If it rains, I will stay at home.`

The zero conditional is used to describe actions or events that are always true when a certain condition is met, while the first conditional is used to describe actions or events that are likely to happen in the future if a certain condition is met.

Yes, the order of the clauses can be changed in the zero and first conditional, but a comma must be used to separate the clauses. For example, `The ground gets wet if it rains` (zero conditional) or `I will stay at home if it rains` (first conditional).
