Sometimes the expected actions depends on a condition ( like if you hurry… or if you come…, etc). Such clauses are called conditional
clauses. In other words, an event depends on the occurrence of the other event. Conditional clauses occur only when a condition is
concerned. Conditional clauses consist of two sentences. One is a clause that starts with if, which is called as ‘if clause’.
The other is called the Main Clause. Each sentence has a verb. It is important to know which tenses are to be used in these clauses and they
play a big role in determining the meaning of the sentence. There are five kinds of conditional clauses. These are known as type 0, 1, 2, 3, 4.
Shortly:
If clause (condition) + Main clause (result) = Conditional Clauses
If Clauses – Type 0:
The tenses in ‘ If Clauses – Type 0’ are the simple present.
Form of the type 0:
[table]
Type | If Clause (Condition) | Main Clause (Result)
Type 0 | If simple present (Subject + V1) | Simple present (Subject + V1)
[/table]
Using Type 0:
We use the Type Zero (Type-0) when talking about our habits, our typical behaviors, explanations, guidelines, advices, orders and instructions, general truths, Real World and scientific facts,
Notes:
The sentence can begin with an If Clause or a Main Clause. If the sentence begins with an ‘If Clause’, put a comma between the If Clause and the Main Clause.
(If) + (Simple Present) + (,) + (Simple Present)
(Simple Present) + (if) + (Simple Present)
In Zero Conditional Sentences, you can replace “If” with “When“, because both express general truths. The meaning will be unchanged.
