Zero Conditional

Zero Conditional

1. Definition:The zero conditional is a grammatical structure used in English to express universal truths, scientific facts, and situations that are always true. It describes a cause-and-effect relationship where a certain condition consistently guarantees the same result.

   • Rules: 1:The condition is always or generally true, not a future possibility.
     • Rules: 2:You can replace "if" with "when" and the sentence will mean the exact same thing.
       • Question Word +Do/Does + Subject + Verb + if/when +Subject + Verb
         • Examples : Do you get thirsty if you eat salty food? Does the machine start if you press that button?
     • Rules 3: If the "if" clause comes first, separate the clauses with a comma. If the main clause comes first, do not use a comma.
     • Structure: If + Presente Simple,Presente Simple
       • Examples : 1 If the sun goes down , it gets dark. 2 It gets dark if the sun goes down.
       • If + subject + don't / doesn't + verb, subject + don't / doesn't + verb.
         • Examples:1 If you don't water plants, they don't grow. If it doesn't rain, the grass stays dry.
