Zero Conditional

If+Present Simple-Zero Conditional |
Present Simple |
Conditional Clauses consist of two parts: the If -Clause (hypothesis) and the main Clause (result). When the If Clause comes before the main clause the two sentences are seperated by a comma. We don’t use a comma when the If Clause follows the main clause. We use Zero Conditional to talk about cause and effect when statement is generally true. | |
“If” is used for things that can happen “When” for definite things that always or normally happen | We use the Present Simple in both parts of the sentence. |
If we don’t sleep enough, When spring comes, If the clouds become too heavy, When winter comes, If you heat ice, |
we get a headache. it gets warmer. it rains. birds fly to hot countries. it melts. |
