Conditional Type Zero is used to express a general truth or fact that always happens in the present. It is also used to talk about actions that are always true, regardless of the circumstances.
In this lesson, we will learn how to form and use the Zero Conditional.
Form:
The Zero Conditional is formed by using the present simple tense in both the if-clause and the main clause. The if-clause usually begins with the word "if", but it can also begin with "when" or "unless".
If + present simple, present simple
When + present simple, present simple
Unless + present simple, present simple
Examples:
- If you heat water to 100 degrees Celsius, it boils.
- When it rains, the ground gets wet.
- Unless you study hard, you won't pass the exam.
The Zero Conditional is used to express a cause-and-effect relationship between two things that always happen. We use it to talk about things that are true in general, rather than specific situations.
Examples:
- If you don't water plants, they die.
- If you touch fire, you get burned.
- If you eat too much junk food, you gain weight.
