Zero Conditional
Introduction
The zipper qualified is a structure use for talking about general truths â€" things which always happen under(a) certain conditions. This page will explain how the zero qualified is formed, and when to use it.

1. The structure of a zero qualified time
A zero conditional sentence consists of 2 articles, an if clause and a main clause (In most zero conditional sentences you can use when or if and the meaning will stick around the alike(p).):
if clause| main clause |
If you heat water to hundred degrees,| it boils.|
If the if clause comes primary, a comma is usually used. If the if clause comes second, on that point is no need for a comma:
main clause | if clause|
Water boils| if you heat it to 100 degrees,|
We use the same verb form in each part of a zero conditional: the unsophisticated wassail tense:
if clause| if + substance + simple present verb |
main clause | subject + simple present verb|
2. Using the zero conditional
The zero conditional is used to talk about things which are always truthful â€" such as scientific facts and general truths:
Example | business relationship|
If you cross an international date line, the time changes.| This always happens â€" any time you cross a date line. |
If it rains, the grass gets wet.



| This is fundamentally always true â€" the rain makes the grass wet.|
Wood doesnt burn down if there is no melodic line.| This is a scientific fact â€" woods needs air in run to burn. No air = no fire.|
