English : Zero Conditional

"If the sun sets, it becomes night."

We use the zero conditional when talking about things which are always true, or generally true.

Structure:

If + Simple Present, + Simple Present

Simple Present + If + Simple Present

Examples:

ü If you boil an egg, it becomes solid.

üIf you heat something, it becomes hotter.

üI always listen to music if I jog.

Note:

We can use "when" instead of "if."

Examples:

üWhen I see Karen I always feel better.

üWhen she feels sick she lies in bed.
üHe starts yelling only when he gets really desperate.
